CLOSED-CYCLE POWER PLANT OF AUTONOMOUS POWER SUPPLY SYSTEM OF SPECIAL FACILITIES Russian patent published in 2024 - IPC F02G1/04 B01D53/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely to air-independent power plants with internal combustion engines operating in a closed cycle without atmospheric air access, and can be used when creating a system of autonomous power supply of special objects, operating in conditions of anomalous state of the atmosphere. Power plant of a closed cycle of a system of autonomous power supply of special objects includes: a heat engine, an automatic control system, an inlet system, in-series installed cooler of waste gases, moisture separator filter, recirculation control valve, by its outputs connected to the mixer and to the exhaust gas removal system compressor, a cryogenic tank for storing the liquid oxidizer, heat-insulated pipelines with fittings, including automatic valves, which are connected to the automatic control system by means of control connections, closed gas circuit, including utilization thermal gas turbine engine with compressor and turbine, gas-water cooler and gas-gas heater of utilization gas, it differs by the fact that the diesel generator is additionally introduced as the primary heat engine, the mixer, the separator-divider, the artificial gas mixture heater and the artificial gas mixture receiver, installed in series and forming the intake system, wherein the gas chamber of the waste gases of the artificial gas mixture heater is connected to the output of the diesel generator and to the gas chamber of the waste gases of the gas-gas heater of utilization gas, and the gas chamber of the artificial gas mixture is connected to the separator-divider and to the receiver of the artificial gas mixture, the boiler-additional heater of utilization gas installed in the closed gas circuit, into combustion chamber of which by compressor of exhaust gas removal system part of exhaust gases of diesel generator is supplied and then removed through gas-air paths, at that, the utilization gas boiler-additional heater is connected to the output of the utilization thermal gas turbine engine compressor through the gas chamber of utilization gas of the gas-gas heater of utilization gas and to the inlet of the utilization thermal gas turbine engine, the outlet of which is connected to the inlet of the compressor through the gas chamber of the gas-water cooler of the utilization gas, oxygen gasification and supply system, made in the form of a closed circuit with an intermediate heat carrier, formed, in turn, by successively installed pump, heat exchanger, evaporator-gasifier, the latter is connected by its inlet to cryogenic tank for storage of liquid oxidizer, and by its outlet to gasified oxygen receiver, which in its turn is connected to mixer via pressure reducing valve.

EFFECT: development of the present invention is aimed at increasing the efficiency and reliability of the closed-cycle power plant, stabilizing the pressure in its gas circuit, reduction of energy consumption for own needs and volumes occupied by the equipment, possibility of instantaneous changeover of the power plant to the closed cycle operation mode.
