METHOD FOR VORTEX ENERGY SEPARATION OF GAS FLOW AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2003 - IPC

FIELD: gas industry branch. SUBSTANCE: method comprises steps of supplying compressed gas through pulsator and tangential multinozzle inlet into separating chamber of vortex pipe where compressed gas is separated by near-axial and peripheral flows and it is discharged through diaphragm and diffuser with member for suppressing vortex, respectively; supplying additional flow of compressed gas through second pulsator to near-axial zone of separating chamber with frequency oscillation 0.2 - 2 kHz; ejecting recycled portion of peripheral flow by means of pulsating flow in separating chamber; creating in pulsator for main gas flow volume oscillations of pressure with frequency 4 - 20 kHz and tuning predetermined frequency of said oscillations according to oscillation frequency of additional flow; setting revolution number of additional flow in such a way that it does not coincide with revolution umber of main near-axial flow and setting rotation direction of additional flow in such a way that it is different from rotation direction of main flow. Relation of flowrate values of additional and main flows may be in range 0.01 - 0.05. Relation of flowrate values of near-axial and peripheral gas flows in vortex type energy separator may be in range 0.4 - 0.7. EFFECT: improved thermodynamic efficiency of vortex type energy separator of gas flow. 18 cl, 6 dwg
