Description

The invention relates to a device for generating thermal energy by utilizing excess gas pressure at gas distribution stations (gas distribution stations) and gas distribution points (hydraulic fracturing).

Closest to the invention is a device for heating the coolant according to the patent of the Russian Federation for utility model No. 49960, IPC ⁷ F24H 4/00, F24D 3/02.

The device comprises a gas turbine with a nozzle apparatus and an impeller located in a casing of a gas pipe connected to a gas pipeline, an apparatus for heating a heat carrier (water) using the cavitation effect.

The disadvantage of this device is low efficiency and power.

The objective of the invention is to increase efficiency and power, expand the functionality of the use of the resulting heat energy.

The task is carried out by the fact that in a turbo-plasma hydraulic heater containing a turbine with a nozzle apparatus and an impeller located inside the housing from a gas pipe connected to the gas pipeline, an apparatus for heating the liquid, an electric generator is additionally installed inside the housing, the rotor of which is cantilever mounted on the turbine impeller shaft and a plasma pulse generator (tasitron) is placed outside the housing, while the apparatus for heating the liquid is immersed in a reservoir with a liquid is a transducer of electromagnetic waves coming from a plasma generator into ultrasonic vibrations, moreover, an electric current generated by an electric generator is used to start the plasma generator.

Figure 1 shows a diagram of a turboplasma hydraulic heater.

Figure 2 - design of the device (without apparatus for heating the liquid).

Figure 3 is an electrical diagram of a pulse generator on a tacitron.

Figure 4 - diagram of the apparatus for heating the liquid.

The turbo-plasma fluid hydraulic heater includes a turbine 1, consisting of a nozzle apparatus 2 and an impeller 3, mounted cantilever on the rotor shaft of the electric generator 4. The turbine 1, the electric generator 4 is placed in the housing 5 from a gas pipe connected to the gas pipeline 6. The electric generator 4 is electrically connected through built-in rectifier (not shown in the drawing) with a plasma electromagnetic pulse generator (tasitron) 7 located outside the housing 6. Through an electric cable, the plasma generator 7 is connected n apparatus with electrodes for heating the fluid 8.

The device operates as follows. Gas from the main pipeline 6 enters the nozzle apparatus 2 of the turbine 1. The kinetic energy of the gas exiting the nozzle apparatus 2 is converted into the mechanical energy of rotation of the impeller 3 of the turbine 1 and the rotor of the generator 4. The induction current arising in the stator winding of the generator 4 through the built-in generator 4, the rectifier is fed to the electrodes of the plasma pulse generator 7, which is a tacitron (see figure 3). From the unit for generating the driving pulses (not shown in the diagram), which is also supplied with power from the electric generator 4, the voltage is supplied to the tacitron grid, as a result of which a low-temperature (less than 3000 K) plasma arc is formed between the thyratron electrodes - the tasitron is ignited ", and the cable receives a signal at the electrodes of the apparatus for heating the liquid 8.

A tacitron having a perforated grid design generates electromagnetic pulses with a frequency of up to 300 kHz and a voltage of up to 100 kV.

The apparatus for heating the fluid 8 (see figure 4) is a transducer of electromagnetic waves coming from the thyratron, in ultrasonic (ultrasound). In this case, the ultrasonic transducer is a ferrite plate “sandwiched” between the electrodes and immersed in a reservoir with liquid (water). When ultrasound is generated in water, a cavitation process occurs, which is accompanied by an increase in water temperature near the emitter. By changing the frequency of the control pulses on the thyratron grid, one can also change the ultrasonic frequency and obtain a relaxation process in the liquid (dispersion absorption of ultrasonic in the liquid), i.e. maximum installation efficiency.

Thermal heating of the liquid (water) in the tank can be used for a water supply system, and the steam discharged from the tank can be fed to a steam power plant to generate electricity. The plant efficiency reaches 90%, power - 1 MW.
