GAS-DISTRIBUTING STATION Russian patent published in 2016 - IPC F17D1/04 

FIELD: gas appliances.

SUBSTANCE: invention relates to gas engineering, particularly to gas-distributing stations (GDS) to reduce gas pressure in a gas line. Technical result is reduction of power consumption of a GDS operation due to using thermal potential of the vortex pipe in production of electric potential in the thermoelectric generator. GDS includes a control unit, a process unit with high and low pressure gas lines, a condensate accumulation vessel connected with the HP gas line and through a shutoff member to the LP gas line, an ejector, a vortex pipe installed on the high pressure gas line, herewith the vortex pipe is equipped with a thermoelectric generator including a housing with a channel for the hot flow and a channel for the cold flow, as well as a set of differential thermocouples, herewith “hot” ends of the differential thermocouples are secured inside the hot flow channel, while “cold” ends of the differential thermocouples are secured inside the cold flow channel.

EFFECT: technical result is reduction of power consumption for a GDS operation.
