[0001] The invention relates to a compact, high-temperature-protected smoke or air dilution
and diffusion device intended for resisting high-temperature flue gases consisting
of heat-protection spaces located in a pipe that uses to advantage the full capacity
of the ventilator medium to create a fixed predefined draw or sub-atmospheric pressure
at the top of chimney stacks and ventilation systems with simultaneous dilution, ejection
and dissipation of high-temperature smoke or contaminated air without ingress of fallen-down
atmospheric precipitation in connected functional applications.
[0002] The device is of the kind that, mounted at the top of or within chimney stacks and
ventilation systems, consists of a pipe of a diameter corresponding approximately
to the outer dimension or size of a chimney stack or ventilation system, straight
or curved, material, shape and colour and being internally lined with a thin temperature-resistant,
dampening material, wherein a double-cooled, heat-protected ventilator part is arranged.
[0003] US 4,344,379 Smith et al. teaches a device for roof-mounting, dilution and discharge of contaminated air and
gases at high velocity as an alternative to an industrial stack intended for discharging
contaminated air, and, by means of adjustable dampers for generating an adjustable
draw, adapted to the volume of contaminated air in a ventilation system, and wherein
an electric motor is provided on whose shaft is mounted a combination ventilator blade
consisting of a primary ventilator blade with fan blades that are interconnected with
an auxiliary ventilator blade for cooling of the motor with influent external air,
and means for impelling contaminated air in a specified direction, wherein cooling
air is used, in addition to providing cooling of the electric motor, for diluting
contaminated air. That known device cannot solve the tasks that the present application
has taken on to solve. The device known from
US 4,344,370 is, according to the description, constructed to process contaminated air generated
during industrial processing operations and is not intended for processing of high-temperature
flue gas and contaminated air originating from combustion processes. The concept "chimney"
covers, in the
US 4,344,370 terminology, a ventilation system from industrial processing operations, but terminologically
it does not cover a conventional chimney which, based on choice of materials and requirements,
is constructed to receive ventilation from high-temperature flue gases and contaminated
air generated in combustion-generating or the like high-temperature generating applications.
The device known from
US 4,344,370 is, according to the description, intended for being mounted directly on a roof surface
and is dimensionally too big for being mounted on a conventional chimney or ventilation
system. It will not be able to draw out high-temperature flue gases since the motor
is provided only with conventional cooling for motors in closed spaces. The cooling
blade is not protected against accumulation of soot and tar particles which, during
brief use, sticks to the blades with ensuing considerably reduced cooling function.
[0004] The construction provides a cheaper and more attractive discharge or ventilation
system than a conventional ventilation system of a corresponding height. It is not
allowed in the Scandinavian countries, EU, USA, Canada, and Australia to couple solid-fuel-fired
fireplaces to that kind of device in replacement of a chimney, the construction being
a direct fire and poisoning hazard.
US 4,344,370 focuses on discharge rate of contaminated air to compensate for the height from a
ventilation system as opposed to the present application that focuses on heat protection
of the device and dilution of high-temperature flue gas or contaminated air.
[0005] From Exodraft RSV, a velocity-regulating device is known which is, however, associated
with the drawback that a fixed, pre-determined draw, utilisation of the full capacity
of the device for diluting or diffusing smoke or contaminated air are not obtained
when the device is configured for random regulation of the velocity according to the
user's needs. It is also a distinct drawback that the device known from Exodraft RSV
is mounted on a mineral wool batt arranged between the device and the top of the ventilation
system which prevents air from penetrating below the device for diluting high-temperature
flue gases. It is also a distinct drawback that the device known from Exodraft RSV
is, on its own, not configured for creating a fixed pre-determined draw without coupling
of external equipment in the form of a measurement and control unit for regulating
the draw. It is a distinct drawback that dilution cannot take place without accessory
equipment being mounted in the form of a subsequently fitted flange at the top of
the ventilation system and mounting of spacer bolts to the effect that false air is
introduced below the device. It is also a distinct drawback that, when the velocity
and hence the draw in the ventilation system are regulated downwards, Exodraft RSV
cannot use to advantage the full capacity of the axial blade to create the most comprehensive
cooling, dilution and diffusion possible.
[0006] On the device known from Exodraft RSV, axial blade and motor part are separated by
a plate whose purpose it is to prevent superheating of the motor from the rising hot
flue gas, and to shield the motor in a motor housing which is cooled directly by external
air through small openings in the sides. The size of the plate covers an area larger
than the area of the axial blades just above the flow of smoke or air. The location
of the plate above the axial blades brings about a comparatively large capacity loss.
The axial blades are made as a heavy construction, weight-wise, which entails comparatively
high demands to motor power. If it is taken into consideration that, to provide a
requisite capacity to obtain both draw, dilution and diffusion, and that, for the
sake of driving a weight-wise heavy axial blade, it is necessary to use a device with
a motor larger than foreseen, it is distinct drawback that it entails a multiplication
of the energy consumption.
[0007] By the identical devices known from Kützer und Weber, Injekt and Termatech that apply
the ejector principle to eject smoke up into the air, it is a distinct drawback that
the construction is, by virtue of the open top, not configured for being mounted on
chimneys or ventilation systems where fallen-down precipitation is not allowed to
penetrate into connected functional applications. Taking into consideration that a
large number of users of the connected functional applications are precisely connected
directly to the bottom of a ventilation system, it is a distinct drawback that fallen-down
precipitation may cause damage to parts of the functional application. However, retro-fittable
accessories are available in the form of a rain cover that is arranged over the top
of the device to the effect that down-fallen precipitation does not penetrate into
the connected functional application, but it is a distinct drawback that thus the
device cannot at the same time use the ejector principle of vertical ejection since
the rain cover, by being placed over the top, prevents the intended ejector effect
of the device. By the velocity-regulating device known from Kützner und Weber, Injekt
and Termatech it is a distinct drawback that a fixed, predetermined draw and utilisation
of the full capacity of the device for dilution or dissipation cannot be obtained
when the speed of the motor is regulated arbitrarily subject to user's needs.
Thus, there is a need for a device which is state-of-the-art in respect of fixed draw,
dilution, vertical dissipation, fallen-down precipitation and utilisation of energy
for using to advantage the full effect of the motor and in particular for resisting
high-temperature flue gases and contaminated air which complies with environmental
requirements, service value and requirements to safety and design.
[0008] US 3 199 774 discloses a device according to the preamble of claim 1, having a fan arrangement
within a duct to produce forced flow therein, and particularly pertains to a fan assembly
for installation entirely within a duct. In a typical application of the invention,
the fan assembly is located within a vertical duct of an air conditioner cooling tower
system. Also
DE 844498 and
WO 2012/031295 A1 disclose related devices of the prior art. Thus, the invention relates to a mechanical
double-cooled device for high-temperature flue gas and contaminated air intended for
generating a determined normative or variable draw in chimney stacks and ventilation
systems, wherein draw or sub-atmospheric pressure is instable/poor, and, in operation,
for generating an admixture of air/high-temperature smoke or contaminated air, and
dissipating them upwardly into the atmosphere, axially in the longitudinal direction
of the pipe, for a chimney or a ventilation system, which unit comprises a pipe in
which there is mounted a double-acting cooling unit with a ventilator part, in the
following designated cooling unit/ventilator part, and which is protected against
high temperatures and particles.
[0009] The device according to the invention can be mounted on the top of, or be built integrally
with, chimney stacks or ventilation systems, and consists of a double-cooled ventilator
part arranged interiorly of a pipe of a size approximately corresponding to the outer
dimension, the material, curved or straight, shape and colour of a chimney or a ventilation
system, and which is lined interiorly with a thin resonance-dampening, high-temperature-resistant
material.
The ventilator medium/the cooling unit may, as a separate part, be built into existing
or other chimney/ventilation systems and functional applications. The pipe is made
of metal or other suitable material. The pipe may have a shape that is approximately
round or edged, curved or straight to the effect that the unit can be adapted to all
chimneys and ventilation systems.
[0010] At the top of the pipe, a cooling unit/ventilator part is arranged wherein a motor
is mounted in independently cooled heat-protection cups. In the cooling unit/the ventilator
medium outlying cooling pipes are arranged that, in the outwardly facing end, protrude
outside or are flush with the pipe, and, in the inwardly facing end, in the cooling
unit/ventilator part, end in an air intake above, below, or at the motor. The motor
is secured in an interior cooling cup through which the shaft from the motor is caused
to extend out through a cooling hole at the bottom of the interior cooling cup. Below
the interior cooling cup, the shaft is provided with a ventilator medium of a dimension
corresponding approximately to the diameter of the bottom of the interior cooling
cup, and a height corresponding approximately to the ventilator medium plus requisite
work clearance between top and bottom of interior and exterior cooling cup. The interior
cooling cup containing motor, and blade arranged exteriorly, is arranged down in an
exterior cooling cup of a size that allows optimal amount of cooling air to pass between
bottom and sides of interior and exterior cooling cup, and out through the top of
the exterior cooling cup via a space below the top flange of the interior cooling
cup and the exterior cooling cup. Below the exterior cooling cup, through a hole at
the bottom for the shaft, there is, at the end of the shaft, on an adaptor, mounted
a ventilator medium.
[0011] Below the cooling unit/the ventilator medium a safety grid is arranged or one or
more baffle plates, eg in the form of a set of round, inwardly upwardly oriented rings
having an internal diameter corresponding to the internal dimension of a chimney or
ventilation system, and an external diameter corresponding to the outer dimension
of the pipe on the device. The rings are upwardly oriented with varying inclinations
relative to the performance, but will preferably be about 45°.
[0012] Below the ventilator medium, a heat-protection shield is mounted, arranged in braces
that rest in adjustable or fixed holders on the inside of the pipe, on the flange
or on the rings. The pipe is mounted on a fixed or exchangeable precipitation-deflecting
flange on which a downwardly oriented pipe is mounted of a dimension which, by means
of adaptor rings or adaptor holders, can be conveyed down into all of the current
chimney interiors or ventilation systems. The hole in the flange can be adjusted to
the effect that the draw in the chimney or the ventilation system can be adjusted
as needed. The heat protection shield serves the purpose of forming first heat protection
barrier to protect the motor unit and to divert particles from the hot flue gas or
contaminated air, and to deflect fallen-down precipitation to prevent it from penetrating
further down into the chimney or the ventilation system.
[0013] By the invention is provided a device that, from a design point of view, in size,
shape, and colour, partakes as a natural part of, or is within, a steel chimney, or,
as a less visible part, partakes in size, shape, and colour as a natural part on or
in a brick-built chimney or a ventilation system, which device creates a determined
draw or sub-atmospheric pressure from the requirements made by a manufacturer or authority
to chimneys and ventilation systems connected to the functional application. High-temperature
flue gas or contaminated air is diluted and are aired out at the top for higher degree
of dissipation in the atmosphere. Owing to construction and choice of intelligent
motor control, the energy consumption is very low. Down-fallen rainwater cannot penetrate
down into the chimney or the ventilation system and cause damage to connected functional
applications. By the high-temperature flue gas or contaminated air admixed with air,
the temperature around the cooling unit/ventilator unit is decreased, and, due to
the construction of the cooling unit/ventilator medium with heat protection spaces,
the temperature of the motor is further reduced to an operation level which is, in
respect of the motor, acceptable. To avoid excessive heating of the motor in case
of non-occurrence of manual start-up, one or more sensors is/are arranged as motor
protection in the cooling unit/ventilator medium that starts/start the motor when
the temperature exceeds a given temperature.
[0014] The same sensor(s) start(s) the motor when the smoke or air diluter is, in case of
powerful impact by the sun, heated to a given temperature to the effect that critical
motor parts outside normal operation are cooled to acceptable temperature level, which
prolongs the longevity of the motor.
[0015] According to the invention, this is obtained by using, from a design perspective
and from a construction perspective, materials, size, shape and colour that are approximately
adapted to the chimney or the ventilation system to or in which the device is to be
mounted. From a functional point of view, the invention is characterised, on the one
hand, in that there is arranged, at the top of the pipe, mounted in a top ring, a
shield device that prevents birds from falling down into the pipe and prevents contact
with rotating parts. The top ring with shield may be provided with a short chain or
wire that is secured to the outside of the pipe in which the top ring with grid can
be suspended during servicing.
[0016] Below the top ring, cooling unit/ventilator part can be secured on the pipe with
heat-resistant, vibration-dampening absorbers secured to the pipe, or cooling unit/ventilator
part is secured to the shield which is arranged suspended at the top of the pipe.
The electric cable from the motor part is provided with a multiple outlet enabling
connection of one or more control, measurement or sensor units in the cooling unit/ventilator
medium. The control, measurement or sensor units are arranged on one or more critical
or strategic places in the cooling unit/ventilator medium. The electric cable is conveyed
out through a cooling pipe and down along the pipe to a safety switch that switches
off the motor when the device needs cleaning or maintenance or is conveyed to connectors
at the end of one or more cooling pipes whose purpose it is to disconnect power when
cooling unit/ventilator part is lifted clear of the connectors in the context of servicing
or has been conveyed directly to a control box. Below the cooling unit in the ventilation
openings, a safety grid is secured, or baffle plates, in the form of adapted, inwardly
upwardly oriented rings having an internal diameter approximately corresponding to
the inner dimension of the ventilation pipe, and an external diameter corresponding
approximately to the outer dimension of the pipe, larger than or equal to. The rings
transport the dilution air into the column of smoke or contaminated air that comes
from the top of the chimney or the ventilation system and upwards to the ventilator
medium, and conduct down-fallen rainwater away. The device is secured on a fixed or
exchangeable flange with outward inclination to deflect precipitation and provided
with a downwardly oriented pipe of a dimension which, by means of adaptor rings, can
be conveyed down into all current sizes of chimneys or ventilation systems. Below
the device that abuts on the top of the chimney or ventilation system, a vibration
dampening material/sealing ring is provided that reduces resonance, vibrations and
ingress of precipitation.
[0017] Functionally, the invention is characterised, on the one hand, in that the cooling
air of the cooling unit is drawn in through one or more outlying cooling pipes and
into an air intake mounted on the interior cooling cup in which the upper part of
the motor housing is located. The cooling air cools the motor housing, is then forced
downwards between the external sides of the motor housing and the wall of the interior
cooling cup. The cooling air is conveyed onwards down below the motor housing, out
through an opening at the bottom of interior cooling cup, and out into exterior cooling
cup where the cooling air ventilator medium mounted to the motor shaft forces the
cooling air out into the space underneath the bottom of interior cooling cup and the
bottom of exterior cooling cup, and up the sides between the external walls of interior
and exterior cooling cups. The cooling air then debouches horizontally into the space
between interior and exterior cooling cups' top flange at the top below the air intake
and out into the admixed atmospheric air/high-temperature smoke or contaminated air
that comes from the ventilator medium below the cooling unit/ventilator medium. The
particular construction of the cooling unit/ventilator medium and choice of intelligent
motor type enables adaptation of the cooling unit/ventilator medium to different sizes
of pipes and hence modification of the capacity and energy consumption of the overall
unit merely by elongation of cooling pipe and modification of the dimension of the
ventilator medium in response to the requirements to size/function for chimneys and
ventilation and/or requirements to connected functional applications.
[0018] According to one embodiment, the top of the device is configured to be narrowing
like a nozzle for increasing the velocity of the ejection approximately as an ejector
effect.
[0019] According to a further embodiment, the ventilation openings in the pipe for dilution
air below ventilator part/cooling unit are enlarged by a separate part consisting
of a network, grid or a set of inwardly facing, upwardly oriented rings having an
internal diameter approximately corresponding to the inner dimension of the chimney
pipe or the ventilation system, and an external diameter approximately corresponding
to the outer dimension of the device, larger than or equal to.
[0020] According to a third embodiment, the cooling unit/ventilator medium is arranged underneath
the suspension (facing upwards), wherein the motor part is secured in a single- or
double-cooled cooling unit/ventilator part with cooling pipes that simultaneously
act as legs arranged on/at the flange or suspended from the pipe.
[0021] According to a fourth embodiment, the upwardly oriented rings below the ventilator
medium is secured on the outer side of the pipe with an internal diameter corresponding
to the outer dimension of the pipe and an external diameter corresponding to the outer
dimension of the pipe is larger than or equal to.
[0022] According to a fifth embodiment there is, before and/or after the ventilator medium,
arranged a filter device serving the purpose of purifying the flue gas or the contaminated
air of undesired objects. The filter device is made of metal, ceramic material or
of polymeric material suitable for the purpose. Likewise, the pore or mesh size of
the filter may be varied depending of the purpose, and, likewise, an immersion bath,
an electrostatic or ion-exchange application may partake as a filter.
[0023] According to a sixth embodiment, there is provided, in the unit, two ventilators
between which a filter device is arranged whose purpose it is to purify the flue gas
or the contaminated air of objects.
[0024] According to a seventh embodiment there are mounted sensor- and metrological applications
for control, registration, reporting, safety, logging, and communication.
[0025] The invention will be described in further detail in the following with reference
to figure 1:
Sectional view of cooling unit/ventilator part: Cooling pipe 9 mounted inserted in
cooling top 12 which, on threaded spacer element 13 with welded exterior cooling cup
5, fixates both interior cooling cup 4 and exterior cooling cup 5. Motor 1 is mounted
in interior cooling cup 4 by means of spacer thread 7 attached to motor 1 and at bottom
of interior cooling cup 4 by means of screws. The motor shaft is conveyed through
a larger circular opening at the bottom of interior cooling cup 4 of a dimension that
allows cooling air to pass underneath the motor 1 and further out through the opening
to exterior cooling cup 5. Between the bottom of interior cooling cup 4, and exterior
cooling cup 5, there is, on the motor shaft, securely mounted a cooling medium 8.
The cooling medium 8 draws the cooling air through the interior cooling cup 4 in which
the motor 1 is arranged, and presses the cooling air on down through the opening at
the bottom of the interior cooling cup 4 and out into the space between the internal
cooling cup 4 and the external cooling cup 5 to the cooling medium 8 that is arranged
on the through-going motor shaft in the space of the interior cooling cup 4 and the
exterior cooling cup 5. The cooling air is pressed, via the cooling medium 8, on into
the space between interior cooling cup 4 and exterior cooling cup 5, and up along
the sides between the walls of interior cooling cup 4 and exterior cooling cup 5.
Then the cooling air debouches into the space between interior cooling cup 4 and exterior
cooling cop 5, at the top below cooling top 12, and out into the admixed atmospheric
air/smoke or contaminated air. The motor shaft is caused to continue through a hole
at the bottom of exterior cooling cup 5, on which shaft there is, at the end, mounted
a ventilation medium holder 11 by which the ventilator medium 3 is secured by means
of a screw that has been conveyed through the centres of the ventilator medium 3 and
the ventilator medium holder 11 and up into an internal thread in the motor shaft.
The top of the unit may be provided with a shield device. In the unit, before and/or
after ventilator medium 3, a filter device may be provided.
