VORTEX TUBE Russian patent published in 2003 - IPC

FIELD: hydropneumatic automation; natural gas pressure control at outlet of gas-distribution stations. SUBSTANCE: control center for feeding compressed gas to energy separation chamber is made in the form of slide valve displaced in longitudinal direction by means of servodrive and mounted at inlet of nozzle-type intake. Hot stream discharge pipe provided at chamber outlet has same diameter as chamber and forms, together with end of the latter, annular slit for condensate outlet through radial scroll case enclosing this slit. Chamber and discharge pipe edges are set at acute angle to hot stream. Outlet of hot stream discharge pipe is connected downstream of annular slit past vortex generator to inlet of vortex utilizing ejector mounted downstream of diaphragm at cold end of vortex tube. Ejector and nozzle-type intake are similar devices provided with common slide valve; actuating mechanism connected to pilot device or booster using part of hot stream taken off upstream of utilizing ejector as impulse gas may be chosen to function as servodrive. EFFECT: enhanced efficiency of gas cleaning from condensate; enlarged functional capabilities of vortex tube. 2 cl, 1 dwg
