(54) Device for physical waste treatment


(57) The device for physical waste treatment consists of the grounded Faraday cage placed in a transparent box with a transparent wall opening in which the carrier bridge (9) generators (1,2,3,4,5) of the force fields are placed, at the bottom of the box is the loosely placed stool of an electrically non-conductive material with very high ohmic resistances, which the plastic container (6) lies on for the insertion of the sample (7) for the exposure, while the bottom of the container is made of a thick layer of plastic with a very high ohmic resistance and which is loosely placed on the electrically conductive metal mesh (10) that is connected through an electric wire (12b) with an electrostatic field generator (5) of cold plasma. Above the tank is an electrically conductive metal mesh (11) of the upper plate of the electrostatic field of cold plasma, which is also associated with high voltage electric wire (12a) with the cold plasma generator (5) which is either embedded in the sample or freely suspended above the sample. Carrier bridge (9) is equipped with an electric drive with the possibility of adjusting the speed of movement in two stages.




Description

Technical Fields



[0001] The technical solution relates to the device for the physical treatment of materials (in particular of solid waste matrices) through the effect of force fields.

Background Arts



[0002] Currently there are commercially available devices or the descriptions of the individual units of force fields are known but each of these devices separate. The effects of multiple force fields on the reference object is therefore difficult. Commercially available devices are specialized for a very specific purpose, which usually prevents versatility. A device for a controlled and adjustable electrostatic discharge for exposing the samples does not exist. The conversion of commercially available sources is difficult and their use is quite limited. Only the source of UV radiation is commercially available and usable for variable use (e.g. for hygienisation of infectious waste waters). Other force field generators had to be individually assembled from components suitable for their intended use. The earlier solutions had the already mentioned negative effects of a solo construction, which does not allow for the collective effect of several force fields simultaneously. Another disadvantage is the specific focus of individual units for a single purpose and the necessary processing using only some of the essential parts for the objective pursued. The current technology does not allow superposition force field phenomena - meaning that the simultaneous effect of several force fields in a single matrix in the given (time) period of monitoring the combined effects of the exposed subject, but a gradual shifting of the effects of force fields (one at a time) in the timeline of the exposure, which leads to quite different results.

[0003] Large quantities of waste material without prior treatment must be diverted to a landfill. The appropriate treatment of waste materials reduces their negative characteristics and extends the range of options for recycling, reuse of materials or energy. For instance the slurry from municipal waste water treatment plants are still being, to a large extent, diverted to landfills. The well chosen pre-treatment can be combined with other wastes chosen to use as fuel or fertilisers (e.g. through certified products).

Disclosure of Invention



[0004] The device for physical waste treatment eliminates the listed shortcomings according to this technical solution, the essence of which lies in the fact that it consists of a grounded Faraday cage placed in a transparent box with a transparent wall opening, in which the power generator is located. On the bottom of the box is a loosely placed stool of an electrically non-conductive material with very high ohmic resistance, which the plastic container lies on - the tub for the insertion of the reference matrixes for the exposure of the samples. The bottom of the container is made of a thick layer of plastic with a very high ohmic resistance and is loosely placed on the electrically conductive metal mesh. The mesh is connected through an electric wire with an electrostatic field generator of cold plasma. Above the tank (according to the variant of experiments) is an electrically conductive metal mesh of the upper plate of the electrostatic field of cold plasma, which is also associated with high voltage electric wire with the cold plasma generator either embedded in the sample or freely suspended above the sample. The carrier bridge is equipped with an electric drive with the possibility of adjusting the speed of movement in two stages. The movement is in two directions forward and reverse with an automatic switch of direction in range with the aid of end range adjusting switches. The range of travel is mechanically adjustable (optional placement of the range). For standby electric spark discharge, it is necessary to replace the upper metal grid with the spark gap, which is located on the carrier bridge together with the carrier wheel generator for high voltage electrical discharge; simultaneously, the lower grid must be moved into the container (i.e. in the sample); the wire is then connected to the high voltage generator. Force field generators can operate simultaneously or in various combinations or alone with the exception of the combined effects of the cold plasma force field generator and the high voltage generator electrical discharge generator, which cannot be utilised together due to the connection and mutual interference (damage to the GPS electronics by an electrical discharge) therefore either one or the other separately may be used.
The presented technical solution combines the advantages of variable formations of the force fields and while it also enables the use of solo use of a single field for exposure of matrices.
The technical solution allows the possibility of monitoring the effects of individual effects on the material, but it also allows monitoring either in sub-combinations or globally such as the UV radiation, low temperature plasma, effect of electric discharge and the effect of the electrostatic field on the materials that are being examined.

Made for Carrying out the Invention



[0006] Force filled generators 1, 2, 3, 4, 5 are located in the box inside the Faraday cage 8, which is grounded by a separate copper wire outside the building connected to the ground pin of galvanized steel.

[0007] The cage (8) is made of transparent polycarbonate with an internal metal mesh (Faraday Cage) provided with a front sliding handling wall which is also made of transparent polycarbonate.
The front door is equipped with a main power switch so in the event of an accidental sliding the circuit is automatically and safely disconnected. The main system power switch is located outside the box; individual force field generators I, 2, 3, 4, 5, including mechanical switches are placed inside the box, Furthermore, there is also a drive (including its switches and circuit breakers) of the carrier bridge (9) with the carrier generators 1, 2, 3, 4, 5.

[0008] On the bottom of the box is the loosely placed stool of an electrically non-conductive material with very high ohmic resistance, which the plastic container lies on - the tub (6) for the insertion of the reference sample (7). The bottom of the container is made of a thick layer of plastic with a very high ohmic resistance, loosely placed on the electrically conductive metal mesh (10). The mesh (10) is connected through an electric wire (12b) with the generator (5) of cold plasma. Above the tank (6) (according to the variant of experiments) is an electrically conductive metal mesh (11) of the upper plate of the electrostatic field of cold plasma, which is also associated with the high voltage electric wire (12a) with the cold plasma generator (5) which is either embedded in the sample (7) or freely suspended above the sample (7).

[0009] The carrier bridge (9) is equipped with an electric drive with the possibility of adjusting the speed of movement in two stages. The movement is in two directions forward and reverse with an automatic switch of direction in range with the aid of end range adjusting switches. The range of travel is mechanically adjustable (optional placement of the range). For standby electric spark discharges, it is necessary to replace the upper metal mesh (11) with the spark gap, which is located on the carrier bridge together with the carrier wheel generator (1) for high voltage electrical discharge; simultaneously, the lower mesh (10) must be moved into the container (i.e. in the sample (7)); the wire (12b) is then connected to the high voltage generator (1). Force field generators 2 and 3 can operate simultaneously or in various combinations or alone with the exception of the combined effects of the cold plasma force field generator (5) and the high voltage generator electrical discharge generator (1), which cannot be utilised together due to the connection and mutual interference resulting in damage to the electronics of the generator (5) by an electrical discharge. Therefore either one or the other may be used separately.

Industrial Use



[0010] In practice, it provides several ways of use and utilisation:

Monitoring of the effects of the "aging" of materials due to the effects of force fields;

Degradation of toxic substances in order to determine the most appropriate technology for the commercial use of force fields;

Direct use for decontamination, detoxification and disinfection of hygienisation of materials, matrices, objects, etc.;

Monitoring of the force fields on objects and substances for the purpose of discovering new properties of exposed materials (change properties);

Measurement and quantification of energy of the force fields supplied to the reference materials depending on the expected changes in the properties.



[0011] There is also the possibility of using electronic testing equipment for tracking resistance to the harmful effects of common force fields, depending on the function to determine safe exposure times in which there is no disruption to electronic equipment.

[0012] In practice, the device can be used to monitor the effects of thermal electrical discharge plasma through the effects of electrostatic fields, UV radiation and superposition effects on the material.

[0013] The device can be directly used for the hygienisation of various materials and objects, depending on the nature of contamination and the characteristics of treated subjects.

[0014] The device can be modularly expanded via components by connecting additional generators such as the microwave field, ultrasonic generator or a laser, in different environments (in the atmosphere of variable composition), thus further expanding the use in the research of the influence of force fields and environments in order to study new properties - resistance of materials , their cleaning, sanitation and disinfection - or "aging" and fatigue due to the affect of various fields and different environments.
