Description

Technical field

[0001] An invention belongs to the heating engineering devices, in particular to the devices for heating the liquid and generating steam which can be used for heat supply.

Background

[0002] For heating the houses and different industrial buildings there already have been used for a long time the heating engineering devices in which the heating of liquid and, at a necessity, generating of steam, is carried out by the transmission of heat from a hot working medium to the liquid. Thus the obligatory condition of such process is a necessity to have a working medium with a temperature more than temperature to which it is necessary to warm a liquid. The use of gases of incineration of fuel such, for example, as natural gas or fuel oil is most widespread for such working medium. The basic lack of the use of such heating engineering devices is a low coefficient of efficiency (CE), which in the best devices does not exceed 40 percents, and in most cases in the conditions of production the real CE makes only 20-25 percents. Gases of incineration of fuel after the use have a temperature far less than temperature of surrounding environments, and this heat is seldom used, the warm gases are simply thrown out in an atmosphere.

[0003] In addition, the use of gases of incineration of fuel creates an ecological problem - these gases contain the harmful oxides of nitrogen, sulphur, carbon, and the emission of unrefined gases results in contamination of atmosphere. Application of facilities and equipment for cleaning of gases of incineration of fuel complicates the installation of heat supply and increases charges for the heat supply.

[0004] As an alternative to the heating engineering devices with a hot working medium there are devices in which the warming of liquid takes place at the terms of creation of motion of liquid with certain hydrodynamic parameters, thus the kinetic energy of motion of liquid changes into thermal energy and the liquid is heated.

[0005] There are known devices for heating liquids, in which a liquid is heated, when it passes through the device, in which there is an immobile element (stator) and mobile element which is revolved (rotor). In literature such devices are often called the heat-generators. And, there is a known device for heating the liquid (the patent of the USA of US 6823820 B2, F22B 3/06, is published 30.11.2004), in which a liquid is heated when it passes through a gap between the internal walls of the housing of stator and external walls of the housing of rotor. The housing of stator consists of two housing elements - the front and back ones, which are united with each other. The axial openings are made in the housing elements through which the shift of a cylinder form passes. The front housing element has an external form o a cylinder with two walls - butt end and lateral. The internal surface of the butt end wall has a form of a ring and the internal surface of lateral wall has a form of a truncated cone. The back housing element has a form of cylinder in which one of surfaces of wall in form of a ring is internal.

[0006] At connection of the housing elements the butt end wall of front the housing element a wall of back the housing element is spatially opposite, the lateral wall of front the housing element is located between them, here an internal surface of butt end wall of front the housing element and internal surface of wall of back the housing element is perpendicular to the conditional longitudinal ax of billow. In the collected housing there is a chamber the volume of which is limited to the internal surfaces of three walls of the housing elements, and which has a form of a truncated cone.

[0007] On the shaft a rotor is fastened which is located in a chamber. A rotor is made with three walls and has a form of a truncated cone, the external surfaces of walls of which are conjugate with a gap in accordance with the internal surfaces of walls of the housing. In the housing of rotor there is the through axial channel made accordingly to the longitudinal axis of the rotor the openings of which go out to two opposite walls of the frame of rotor. The shaft passes through an axial channel in the housing of the rotor. The external surface of the walls of the housing of the rotor is made smooth.

[0008] The two channels are made in the walls of front housing element of stator for an input and output of liquid - the channel of input of stream of liquid passes through the lateral wall of the front housing element, the channel of output of liquid passes through the butt end wall of the front housing element. A liquid which enters in a device under pressure gets in gaps between the internal surfaces of walls of the housing of stator and external surfaces of walls of the housing of rotor. The flow of the liquid at a contact with the walls of rotor which is revolved begins to move in the turbulent mode. On the surface of walls of stator the motion of part of stream of liquid is decelerated and the kinetic energy of motion of liquid changes into thermal energy and the liquid is heated. The efficiency of heating the liquid in a device depends on the degree of turbulence of stream of liquid and degree of decelerating of stream of liquid - the higher degrees of turbulence and decelerating of stream of liquid in the device the more the liquid is heated.

[0009] The lack of the known device is low efficiency of heating the liquid. It is related to the structural features of device: the external surface of basic walls of rotor is made smooth and has a small area - that is why for achievement of the certain value of turbulence of stream of liquid the considerable speeds of rotation of rotor are needed, and accordingly considerable charges of energy are needed; the enter of stream of liquid to the rotor through one channel results in the unevenness of turbulence in the volume of stream of liquid and decline of degree of turbulence stream of liquid; a device can work only in the small range of volume of speed of stream of liquid - with change of volume speed of stream of liquid the time of contact of stream of liquid with the surface of walls of rotor at the turbulence of stream of liquid and degree of turbulence of stream of liquid which results in diminishing of degree of turbulence of stream of liquid and decline of temperature of heating the liquid.

Information which confirms the possibility of realization of invention

[0025] On figures 1-8, shown as examples, is one of possible variants of implementation of heat-generator for heating the liquid, one of possible variants of implementation of the shaft for this heat-generator and one of possible variants of implementation of stator for this heat-generator.

[0026] The heat-generator for heating the liquid (Fig.1) contains stator 1, the housing of which has three walls - the first wall 2, the second wall 3 and the third wall 4. The first and second walls of the housing of stator are spatially opposite. The third wall of the housing of stator is located between the first and the second walls of the housing of stator. The housing of stator is located on a supporting plate 5.

[0027] The first and the second walls of stator are executed with the axial openings 6 and 7, through which the shaft 8 passes.

[0028] The housing of the shaft has a form of cylinder (Fig.1,2) and is executed with an axial channel 9, that ends with opening 10 on one of the butt ends of the shaft. In the housing of the shaft a few radial channels 11 are also executed, which walk away from an axial channel and go out on the external surface of the housing of the shaft. Radial channels can be executed in such way that axes of channels can be perpendicular or sloping in relation to the conditional axis 12 of rotation of the shaft. On Fig.2 the variant of implementation of radial channels is shown with sloping in relation to the conditional axis of rotation of the shaft. In an axial channel an element 13 is located for the turbulence of stream of liquid. The shaft is connected with walls of stator by bearings 14 and 15, located in the axial openings in walls of stator. One end 16 of the shaft goes out outside and it is connected with an engine (not shown) by which is carried out the rotation of the shaft. As an engine can be used any known engines, for example, electric motors or engines of internal combustion.

[0029] The first and the second walls of the housing of stator are executed with internal surfaces 17 and 18 (Fig.1), that have a form of a truncated cone and identical direction of tapering of internal surfaces of walls. The third wall of the housing of stator is executed with an internal surface 19 that has a cylinder form. In the third wall of the housing of stator a channel 20 is also executed for the passage-way of liquid (Fig.3). The internal surfaces of walls of the housing of stator limit the volume of chamber into the housing of stator.

[0030] In the volume of chamber a rotor 21 is locate (Fig.1,2), the housing of which is firmly connected with the shaft. The housing of rotor contains three walls - the first 22, the second 23 and the third 24 (Fig.2). The walls of the housing of the rotor are executed in such way that external surfaces of the first, second and third walls of the housing of the rotor are conjugated with a gap accordingly with the internal surfaces of the first, second and third walls of the housing of stator. In the first wall of the housing of rotor a few internal channels 25 are executed, through which the stream of liquid passes. The internal channels of the first wall of the housing of rotor are executed so that entrances to the internal channels were in places nearest to the conditional axis of rotation of the shaft, and exits from internal channels on the external surface of the first wall of the housing of rotor were in places most remote from the conditional axis of rotation of the shaft. The flow of liquid gets to the internal channels of the first wall of the housing of rotor through radial channels in the housing of the shaft.

[0031] On one of walls of the housing of stator, which has the axial opening, is located spirulate to the axial opening of wall of the housing of stator and the shaft entrance branch pipe 26 for a liquid (Fig.1).

[0032] The heat-generator works as follows. An engine drives the shaft of heat-generator and rotor of heat-generator into rotation. Liquid, for example, water, is given by a pump to the entrance branch pipe for a liquid. By passing through the entrance branch pipe the flow of liquid gets in the axial channel of the shaft. There is the first stage of turbulence of stream of liquid in the axial channel of the shaft - when an element influences the stream of liquid for the turbulence of stream of liquid. Then the general stream of liquid is distributed into few even streams and passes through radial channels in the housing of the shaft, whereupon streams get in the internal channels of the first wall of the housing of rotor. A presence of axial channel and radial channels in the housing of the shaft allows distributing the flow of liquid evenly on the plane of rotor, and a presence of element for the turbulence of stream of liquid in the axial channel of the shaft increases the degree of turbulence of stream of liquid in the heat-generator.

[0033] The streams of liquid move in internal channels in direction from the conditional axis of rotation of the shaft. Because of the rotation of rotor the streams of liquid in internal channels get an additional centrifugal acceleration, due to that there is an increase of speed of streams of liquid and the degree of turbulence of streams of liquid rises. Presence of internal channels in the first wall of the housing of rotor and implementation of the first wall of the housing of rotor in form of a truncated cone allows to increase length of internal channels in a wall and accordingly to get greater speed of streams of liquid and greater degree of turbulence of streams of liquid.

[0034] After passing the internal channels of the first wall of the housing of rotor the streams of liquid go out on the external surface of the first wall and get in a gap between the external surface of the first wall of the housing of rotor and internal surface of the first wall of the housing of stator, where on the walls of stator there is decelerating of part of stream of liquid and heating of the liquid. The implementations of conjugating external surface of the first wall of the housing of rotor and internal surface of the first wall of the housing of stator in form of the truncated cones increases surface with which it contacts and at which the stream of liquid is decelerated and accordingly a part of stream of liquid which will be decelerated is increased.

[0035] Then the flow of liquid passes through the area of gap between the external surface of the third wall of the housing of rotor and internal surface of the third wall of the housing of stator, whereupon the heated liquid goes out from heat-generator through a channel in the third wall of the housing of stator. In a gap between the external surface of the third wall of the housing of rotor and internal surface of the third wall of the housing of stator there is additional turbulence and additional decelerating of stream of liquid which results in the increase of heating the liquid.

[0036] As a variant, in the housing of necessity of generation of steam, it is shown in Fig.3 a possibility of implementation in the second wall of the housing of stator of another channel 27 for the output of steam.

[0037] A little part of stream of liquid gets in a gap between the external surface of the second wall of the housing of rotor and the internal surface of the second wall of the housing of stator which also brings in a certain contribution to efficiency of heating the liquid and increases the temperature of liquid at the exit from the heat-generator.

[0038] As one of possible variants in the heat-generator there can be used stator according to the item of formula 4-10, which contains the first housing element 28, the second housing element 29 and the third housing element 30. The first and second housing elements of stator are executed with the axial openings 31 and 32.

[0039] The first housing element contains a basic wall 33 and the butt end wall 34. The basic wall of the first housing element is executed with an internal surface 35 in form of the truncated cone. The butt end wall of the first housing element is executed with an internal surface 36 in form of a ring.

[0040] The second housing element contains a basic wall 37 and the butt end wall 38. The basic wall of the second housing element is executed with an internal surface 39 in form of the truncated cone. The butt end wall of the second housing element is executed with an internal surface 40 in form of a ring.

[0041] The third housing element contains the wall 41, which is executed with an internal surface 42 of a cylinder form. In the wall of the third housing element there is a channel for the passage-way of liquid.

[0042] The housing elements of stator are united between them so that the third housing element is located between the first and second housing elements, and the basic walls of the first and second housing elements have an identical orientation of tapering of internal surfaces of the walls.

[0043] In addition, there on the internal surface of basic wall of the first housing element additionally can be executed a few rows of the first blind openings 43 (Fig.4,5) so that the first blind openings are spatially located in every row on identical and certain distance for every row from the conditional longitudinal axis of stator. The presence of the first blind openings increases the area of surface of stator, with which the stream of liquid contacts and the degree of decelerating of stream of liquid is accordingly increased.

[0044] On the internal surface of the butt end wall of the first housing element there additionally can be executed a row of the second blind openings 44 (Fig.4,5) so that the longitudinal axes of all of the second blind openings are located on identical distance from the conditional longitudinal axis 45 of stator. The presence of the second blind openings increases the area of surface of stator, with which the stream of liquid contacts and the degree of decelerating of stream of liquid is accordingly increased.

[0045] On the internal surface of the butt end wall of the first housing element additionally the flange 46 of a ring form can be executed (Fig. 4,6), and surface 47 of the flange, that faces the conditional longitudinal axis of stator, it has a form of continuous wave with the regular reiteration of fallows and combs. Presence of the flange of a ring form and the form of surface of this flange increases the area of surface of stator, with which the stream of liquid contacts and the degree of decelerating of stream of liquid is accordingly increased.

[0046] On the internal surface of the third housing element additionally there can be executed a few rows of the third blind openings 48 (Fig.7,8), all of the rows have an identical amount of the third blind openings, and the third blind openings in every row are located so that the axes of the third blind openings are in the plane of conditional circle at the identical distance to each other and are displaced in relation to the axes of the third blind openings in nearby rows at a certain step. The presence of the third blind openings increases the area of surface of stator, with which the stream of liquid contacts and the degree of decelerating of stream of liquid is accordingly increased.

[0047] On the internal surface of basic wall of the second housing element additionally there can be executed a few rows of the fourth blind openings so that in every row the fourth blind openings are spatially located at identical and certain distance from the conditional longitudinal axis of stator for every row. These rows of the fourth blind openings are executed like to the rows of the first blind openings 43 on the internal surface of basic wall of the first housing element and that is why not shown on drafts. The presence of the fourth blind openings increases the area of surface of stator, with which the stream of liquid contacts and the degree of decelerating of stream of liquid is accordingly increased.

[0048] On the internal surface of the butt end wall of the second housing element additionally there can be executed a row of the fifth blind openings so that the longitudinal axes of all of the fifth blind openings are located at identical distance from the conditional longitudinal axis of stator. This row of the fifth blind openings is executed alike to the row of the second blind openings 44 on the internal surface of the butt end wall of the first housing element and that is why it is not shown on drafts. The presence of the fifth blind openings increases the area of surface of stator, with which the stream of liquid contacts and the degree of decelerating of stream of liquid is accordingly increased.

[0049] Examples only illustrate the group of inventions but they do not limit it.
