Description

The invention relates to heat engineering, namely to heat generators, and can be used for primary and backup heating of premises for any purpose, for the prompt restoration of the conditions of life support in emergency situations in the absence of all types of energy supply.

Known cavitation-vortex heat generator (see application RU No. 2002119773 from 07.22.2002, IPC F24J 3/00, publ. BIPM No. 9, 03/03/03), adopted as a prototype. The heat generator comprises a housing having nozzles for supplying a heated fluid and removing heated fluid, located inside the housing, a perforated stator consisting of one or more annular disks, and a rotor made in the form of two coaxial disks installed with a gap relative to each other, an injection pump, rotor drive. In this case, the rotor disks are mounted on independent shafts having independent independent drives, and rotate towards each other.

The disadvantages of the prototype are the need for stationary installation of the heat generator during its operation, its narrow functionality, which limits the scope of the device, large heat losses during operation.

The proposed invention solves the problem: ensuring mobility, autonomy, environmental friendliness, increasing the efficiency of heat-generating devices of cavitation-vortex type.

The technical result obtained by carrying out the invention is multifunctionality, in reducing heat loss during operation.

The specified technical result is achieved in that in a mobile multifunctional thermal station (MMTS) containing a stator housing having nozzles for supplying a heated fluid and removing a heated fluid, a rotor made in the form of two coaxial disks, a discharge pump, and a rotor drive are new that the stator housing is made of two-chamber, one of the disks is placed in the first chamber with the possibility of rotation by an electric motor, and the other is placed in the second chamber with the possibility of rotation of the power plant (diesel or gasoline engine), connected to an electric generator, which ensures the operation of auxiliary units and electrical equipment of MMTS in the absence of electricity. The outlet pipes of the working chambers are connected to heat-insulated boiler-accumulators, which are connected to the unit for connecting to the consumption system, and the cooling system of the power unit is connected to a heat exchanger placed in the boiler-accumulator, and all station elements are rigidly installed in the mobile transportation container. The regulation of heat production is performed due to the possibility of changing the number of revolutions of the electric motor associated with the frequency converter, or by changing the number of revolutions of the power plant. MMTS is equipped with a heat exchanger and an exhaust gas neutralizer.

The execution of the stator housing of the heat-generating unit with two chambers is due to the need to ensure both separate and joint operation of two independent drives operating from different energy sources, which allows you to organize the operation of a mobile multifunctional heat station under various conditions of power supply during emergencies in heat and hot systems water supply, as well as to provide thermal energy to structures during the construction period.

The disk, placed in the first chamber on the shaft, is driven by an electric motor connected to this shaft by means of a coupling. When pumping liquid under pressure from a discharge pump through a chamber with a disk rotating inside, it is heated. The operation of the first chamber driven by an electric motor is carried out in the presence of electric energy at the facility. In this case, the rapid deployment of MMTS is possible, its connection to the heat consumption system and the operational start of operation.

The disk located in the second chamber is driven in rotation from the power take-off shaft of the power plant (diesel or gasoline engine). The processes of heat generation in the second chamber are similar to the processes occurring in the first chamber. The operation of the second chamber with a drive from the power plant is carried out in the absence of electric energy at the facility or, if necessary, obtaining the maximum amount of thermal energy due to the involvement of both drives. In any case, the operational deployment of MMTS is ensured.

If necessary, the power plant in conjunction with the electric generator can provide the operation of auxiliary units necessary for emergency and construction work, such as a pump for emergency pumping of water, a drill, a jackhammer, etc. The generator is also used for backup power supply of MMTS electrical equipment in the absence of electricity at the facility.

In order to utilize the thermal energy of the cooling system and the exhaust system of the power plant in useful work, the cooling system is connected to the heat exchanger located in the boiler-accumulator through the exhaust heat exchanger, which minimizes heat loss.

All elements of MMTS: heat generating unit, electric motor, power plant, electric generator, boiler-accumulators that are connected to the unit for connecting to the consumption system, control cabinet, forced ventilation system mounted if necessary, are rigidly installed in the mobile transportation container. This allows you to quickly deliver MMTS to the place of deployment, as soon as possible to make its connection to the heating systems of the facility. Operation MMTS occurs autonomously.

Regulation of heat production by changing the number of revolutions of the electric motor using a frequency converter located in the control cabinet, as well as by changing the number of revolutions of the power plant is due to the need to optimize the heat transfer mode in the heat consumption system.

Technical solutions with features distinguishing the claimed solution from the prototype are not known and do not follow explicitly from the prior art. This suggests that the claimed solution is new and has an inventive step.

The invention is illustrated by drawings, where figure 1 shows a General diagram of a mobile multifunctional thermal station; figure 2 is a General diagram of a heat generating unit.

A mobile multifunctional thermal station consists of a container 1 for mobile transportation (a car trailer of the Kung type, etc.), on the basis of which a heat generating unit 3, an electric motor 4, a power unit 5 (diesel or gas engine), an electric generator are installed on a single frame 2 6, the discharge pump 7. The power plant 5 and the electric generator 6 can be made as a single product - a benzoelectric or diesel-electric unit.

The heat generating unit 3 consists of a stator housing 8 with two chambers 9, 10, inside of which disks 12 are rigidly mounted on the shafts 11 and are rotatably mounted on the shafts 11. The shafts 11 are mounted in bearing bearings 13 and sealed by mechanical seals 14 located in the chambers 15. On the internal end rows of non-through holes 16 are made on the surfaces of the stator housing 8 and the end and cylindrical surfaces of the disks 16. On the disks 12, through holes 17 are made in the immediate vicinity of the shafts 17. In the partition of the stator housing 8 coaxially to the shafts 11 Fuss aperture 18. Branch pipes for supplying heated fluid 19 through the chamber 15 to set the end seals 14 are associated with the cameras 9, 10, and pipes for discharging the heated liquid 20 are mounted on the cylindrical surface of the stator body 8.

The motor shaft 4 and the power take-off shaft of the power unit 5 are connected to the shafts 11 of the heat generating unit 3 by couplings 21, 22. The nozzles for supplying the heated fluid 19 and the nozzles for draining the heated fluid 20 are connected to the storage boilers 23, hoses rigidly mounted on the base of the container 1 high pressure 24. Boilers-accumulators 23, in turn, with similar sleeves 24 are connected to the block connecting 25 to the consumption system. The inlet of the injection pump 7 through the collector 26 is connected to the outlet pipes of the boiler-accumulators 23. The output of the injection pump 7 through the collector 26 is connected to the pipes for supplying the heated fluid 19 of the heat generating unit 3. The operation of the MMTS is carried out by means of a control cabinet 27. Connection block 25 to the heat consumption system and the control cabinet 27 are rigidly mounted in the container 1.

The cooling system of the power plant 5 through a heat exchanger 28 is connected to a heat exchanger 29 located in the boiler-accumulator 23. The exhaust gases cooled in the heat exchanger 28 enter the exhaust gas neutralizer 30 (purification system).

If necessary, a forced ventilation system 31 can be installed in the mobile transportation container 1.

Mobile multifunctional thermal station operates as follows. After prompt delivery to the place of operation, the direct and return pipelines of the heat consumption or hot water supply system must be connected to the connection unit 25. If there is an electric power source at the facility, the control cabinet 27 must be connected. After filling the heat consumption system, boilers-accumulators 23, heat-generating unit 3 with liquid, it is necessary to start pressure pump 7. Access of the liquid to the heat consumption system in the connection block 25 is blocked. When normal fluid circulation is reached between the heat-generating unit 3 and the boiler-accumulators 21, the electric motor 4 is turned on, and then, if necessary, the power unit 5 is started. It is possible to start both in the reverse order and only one of the drives. After reaching a liquid temperature of 60-80 ° C, the circulation pump of the heat consumption system is turned on and the process of heat transfer from the consumer occurs.

During the operation of the power plant, the electricity generated by the electric generator 6, if necessary, can be used to connect auxiliary devices necessary during the operation, as well as to power the MMTS electrical equipment in the absence of electricity at the facility.

The operation of the heat generating unit 3 is as follows. The liquid from the injection pump 7 is supplied under pressure through the manifold 26 to the nozzles for supplying the heated fluid 19 and then through the chambers 15 into the chambers 9, 10. Due to the friction forces between the inner surfaces of the stator housing 8 and the end and cylindrical surfaces of the disks 12, due to the discontinuity of the continuous flow of a liquid medium in the zones of vortex formations in the regions of through holes 16 heat release processes occur. The through holes 17 serve to ensure the flow of the heated fluid into the gap between the partition wall of the stator housing 8 and the end surface of the disk 12. The hole 18 serves to redistribute the fluid in the chambers 9, 10 when they are used simultaneously. Through the nozzles for draining the heated fluid 20 and the sleeve 24, the heated fluid enters the boiler-accumulators 23 and returns to the inlet of the discharge pump 7.

The exhaust system of the power unit 5 through an independent circuit cooling system in the heat exchanger 28 is connected to the converter 30. Next, the cleaned exhaust gases enter the atmosphere. The liquid of the cooling system, additionally heated by the exhaust gases in the heat exchanger 28, gives off its thermal energy in the heat exchanger 29 of the boiler-accumulator 23.
