The device is intended for use as a heating system for an individual building (cottage) and in heating devices for various purposes. The autonomous heating system contains a closed hydraulic circuit with a gas cushion, a pump connected to a hydrodynamic cavitation type heat generator through a pressure connection with a flow rate regulator, and heat exchangers. In this case, the heat generator is made in the form of a sealed container located in the upper part of the hydraulic circuit and filled with liquid above three-fourths of its height to form said gas cushion in the upper part. The cavitation device is made in the form of at least one jet nozzle and one blade turbine wheel immersed in the liquid of the container. The injector is connected to the liquid flow regulator, and the turbine wheel is located opposite the injector and connected to the energy consumer. This design of the heating system allows for economical heating of the building, while it is possible to carry out the heating process without the use of non-renewable energy sources and without connection to a centralized power network.
DESCRIPTION OF THE INVENTION
The invention relates to the field of heat power engineering and can be used both in heating systems and in heating devices for various purposes.
A device for heating a fluid is known, comprising a heat generator with a liquid accelerator, a heat exchanger, a pump with an electric drive connected to a heat generator through a pressure pipe, and a regulator mounted on a conduit connecting the heat generator to the heat exchanger. The heat generator comprises at least one additional liquid accelerator, a spatial distribution system in which parallel liquid channels are installed with different degrees of reduction in the flow section and a flat grid installed behind the distribution system downstream of the fluid. In this case, the internal cavity of the heat generator before the grid is communicated with the expansion tank (see patent of the Russian Federation No. 2132025 C1, IPC 7 F 24 D 15/02, 20.06.1999).
This device allows you to achieve a temperature increase due to the occurrence in the heating system of the cavitation process, but has a complex design and requires constant supply of electrical energy from a centralized power network.
The closest analogue to the claimed invention is a method of heat generation in a liquid and an apparatus for carrying it out, comprising an electric motor pump, a hydraulic circuit on which the expansion vessel is successively mounted with a piston provided with a device for its movement, a charging nozzle and a centrifugal type cavitator (for example, Multichannel centrifugal nozzle). After the cavitator, a heat exchanger is installed in the hydraulic circuit to transfer heat to the consumer. The hydraulic circuit is equipped with a throttle, temperature and pressure sensors. The expansion tank, in turn, contains a drain valve (see patent of the Russian Federation No. 2061195 C1, IPC 7 F 24 J 3/00, May 27, 1996).
In a closed loop with a liquid, gas inclusions can be formed only if there is a volume in the circuit that is free of liquid. An increase in the total volume of gas inclusions and the gradient of the change in the velocity of the liquid is realized by the organization of a vortex flow of a liquid. In this case, the bubbles are formed mainly in the thickness of the liquid, which ensures the safety of the walls of the hydraulic circuit and, accordingly, increases the reliability of work and increases the durability. The present invention makes it possible to provide the heat release process by achieving an autooscillating cavitation mode. However, it is rather difficult to achieve optimal management of this process and, as the complainant himself points out, computer support is required for successful implementation, and a constant supply of electrical energy from a centralized power network is required.

The invention is illustrated by a graphical material, wherein in FIG. 1 shows a general view of an autonomous heating system, and FIG. 2 is a top view of a cavitation device.
The autonomous heating system comprises a closed hydraulic circuit 1 with a gas cushion 2, a pump 3 connected to a hydrodynamic cavitational type heat generator via a pressure connection 4 with a liquid flow regulator 5 and heat exchangers 6 and 7, the heat generator being in the form of a sealed container 8 located in The upper part of the hydraulic circuit 1 and the filled liquid above three quarters of its height to form said gas cushion 2 in the upper part. The cavitation device is made in the form of at least one jet nozzle 9 and one blade turbine wheel 10 immersed in the liquid of the container 8, the nozzle 9 is connected to the liquid flow controller 5 and the blade turbine wheel 10 is located opposite the nozzle 9 and is connected to the consumer Energy 11. A motor 12 and / or a wind turbine 13 and / or a diesel engine (not shown in FIGURE 1) connected to the pump 3 via couplings 14 can be used as the pump drive 3. The pump drive motor 3 12 can be configured as Reversible electric machine connected to the battery 15.
The final heat exchanger 7 can be located in the well 16 with groundwater located in the basement of the building or outside. In this case, an overflow valve 17 can be installed in front of the heat exchanger 17 to supply the working fluid through the additional line 18 to the pump 3, bypassing the heat exchanger 7. The well 16 can be provided with a line 19 for collecting groundwater through the filter 20, and as a pump used for its For example, said consumer 11. In addition, the container 8 is provided with a temperature sensor, a charging nozzle, a drain valve and a water tube (not shown in FIG.
HEATING SYSTEM OPERATION IS FOLLOWED AS FOLLOWS:
A closed loop 1 is filled with a working fluid, for example water, through the filling connection of the container 8. The container 8, located in the upper part of the circuit 1, is filled with liquid above three-fourths of its height. In this case, the jet nozzle 9 and the blade turbine wheel 10 must be immersed under the water level of the container 8, and in the upper part of the container 8, a gas cushion 2 is necessary to saturate the water with air and ensure the flow of the cavitation process.
When the pump 3 is turned on, water circulates through the closed circuit 1, with the help of the liquid flow regulator 5, a cavitation process is created in the vessel 8, the intensity of which is judged by the temperature sensor. In order to increase the power of the heating system, several jet nozzles 9 and opposite blade turbine wheels 10 fixed to one power take-off shaft with a blade shift of each wheel relative to each other can be installed, wherein the power take-off shaft is connected to the energy consumer 11, An electric generator, a pump, or other mechanism requiring a drive may be used.
The heat generated by the heat exchangers 6 and 7 can be used both for heating the building itself and for heating groundwater in the well 16, which can be used, for example, by a pump (an energy consumer 11), a pipeline 19 and a filter 20 Needs. If there is no need for water from the well 16, water can be circulated through the bypass tap 17 and the pipeline 18 bypassing the last heat exchanger 7.
The drive of the pump 3 is oriented more towards the use of wind energy, which, by means of a windmill (windmill 13), can drive both the pump 3 directly and the reversible electric machine 12 which operates in the generator mode and supplies the battery 15 , The energy of which can be used by the same electric machine 12 operating in the driving mode and driving the pump 3 in the absence of wind. However, pump 3 can operate in emergency situations from the diesel and from a centralized electrical network.
