METHOD OF AND DEVICE FOR VORTEX ENERGY SEPARATION OF FLOW Russian patent published in 2004 - IPC

FIELD: gas industry. SUBSTANCE: invention relates to vortex converters of pressure differential energy on gas-distributing stations of trunks. According to proposed method, compressed gas is delivered into separating chamber of vortex pipe through pulsator and tangential multinozzle input where it is divided into near-axis and peripheral flows and is brought out through diaphragm and diffuser with swirler, respectively. Additional flow of compressed gas is delivered through second pulsator into near-axis zone of separating chamber at f₁ = 0,4-4kHz. Recirculated part of peripheral flow is ejected by means of pulsating flow in separation chamber. Volume oscillations at frequency of f₂ - 8-32 kHz are created in pulsator of main gas flow and preset temperature and frequency of volume oscillations of main flow and those of additional flow swirler flow ω₁ is set as multiple to speed of rotation ω₂ of near- axis main flow, and external energy of additional flow is subsequently depleted in one or more stages of ejector by adding gas of additional flow. EFFECT: improved efficiency of vortex energy divider.
