GAS DISTRIBUTION STATION Russian patent published in 2012 - IPC F17D1/04 

FIELD: machine building.

SUBSTANCE: gas distribution station comprises control unit, service unit with low- and high-pressure gas pipelines, and gas condensate collection tank communicated with high-pressure gas line and, via shutoff valve with low-pressure pipeline. Ejector and vortex tube are arranged at high-pressure pipeline. Ejector outlet is communicated with vortex tube inlet while tube hot flow outlet communicates with heat exchanger inlet. Note here that heat exchanger outlet is communicated with ejector mixing chamber. Note also that heat exchanger inlet represents converging nozzle with helical grooves on inner surface groove generator is directed clockwise. Note also that heat exchanger inlet represents diverging nozzle with helical grooves on inner surface groove generator is directed counter clockwise. Heat exchanger is arranged on gas station internal heating system pipeline. Note here that vortex tube is furnished with thermoelectric generator made up of housing with flow channels for hot and cold flows. It comprises also the set of differential chambers with their cold ends located in cold flow channel of gas vortex tube. Hot ends are arranged in hot flow channel. Cold flow channel communicates via inlet with tube cold flow inlet and, via outlet and hot-well, with condensate collection tank. Hot flow channel inlet communicates with vortex tube hot flow outlet while its outlet communicates with heat exchanger inlet.

EFFECT: electric power production for emergency lighting, higher station efficiency.
