Multiple air-intaking channel and supersonic speed whirl-flow separator and its back pressure device

A multi-port supersonic cyclonic fluid separator and the back pressure device comprises a flow chamber and flow chamber communicating with the nozzle and cyclone separation stage, cyclone separation stage back pressure outlet communicating, in further provided between the back section and the cyclone separator pressure annular liquid discharge port, is provided on the back pressure has an adjustable positioner gap discharge port, uniform distribution of said plurality of nozzles of the nozzle, and the nozzle and the angle between the inner surface of the cyclone separator segment 78-90 degrees, the angle between the axis of the nozzle and the separation section is a cyclone 40-62 degrees. The present invention is implemented using a multi-nozzle air moisture condensing the saturated gas separation supersonic, air evenly into the flow chamber so that the nozzle; the flow of air nozzle a high growth rate, moisture condensation temperature is lowered to the desired degree of supercooling or less ; cyclone separation stage in the gas-liquid two-phase high-speed rotation of the separation chamber, to achieve gas-liquid separation; liquid film flow discharge port and away from the wall surface of the cyclone separation chamber; back pressure allows the dry gas after further back pressure, achieve deceleration and heated.
