FIELD: machine building.SUBSTANCE: compressor plant includes compressor, waste heat exchanger, aftercooler and air receiver, which are installed in a pressure line and connected to each other by means of the main and additional pipelines, which are equipped with valves electrically connected to a control unit, and air mains. Compressor is connected by means of suction pipeline to air filter representing a housing with a cover plate and a conical bottom. A float-condenser is installed in lower part of filter. Upper part of the housing is provided with a device made in the form of a convergent nozzle, to the inlet opening of which a net is attached, and after its outlet opening a deflecting baffle is installed. Suction pipeline is connected to the filter housing cover plate. In addition, housing of the filter is equipped with a jacket forming a cavity to be filled with hot compressed air. The cavity in lower part of conical bottom is connected by means of a valve and an additional pipeline to a discharge line, and in upper part of the housing - to the convergent nozzle. A thermoelectric generator is installed in the discharge line connected via additional pipelines to the compressor. Thermoelectric generator is made in the form of a housing with a through channel for compressed hot air and a set of differential thermocouples. Hot ends of thermocouples are located in the through channel for compressed hot air, and their cold ends are fixed on external surface of housing of thermoelectric generator far from the through channel for compressed hot air. Inlet of the through channel for compressed hot air is connected to the compressor discharge line, and outlet of the through channel for compressed hot air is connected to the cavity of lower part of conical bottom of the air filter.EFFECT: reduction of power consumption for production of compressed air by reducing power consumption for lighting of a room, by generating the electric energy with a thermoelectric generator using a thermal potential of compressed hot air.2 dwg |
