Abstract
The present invention pertains to the field of jet technology and more essentially to a liquid-gas ejector having a nozzle and a mixing chamber. The area of the minimal cross-section of the mixing chamber of the liquid-gas ejector is determined from the following formula: where F—area of the minimal cross-section of the mixing chamber; k—design factor; Q—volumetric flow rate of a liquid through the nozzle; g—acceleration of gravity; y—density of the liquid fed into the nozzle; Pc—liquid pressure at the nozzle inlet; and where the k factor has a value ranging from 1.6 to 60 when the ratio of the liquid pressure at the nozzle inlet to the pressure of a liquid-gas mixture at the mixing chamber outlet is from 1.4 to 25 and the k factor has a value ranging from 60 to 2200 when the ratio of the liquid pressure at the nozzle inlet to the pressure of a liquid-gas mixture at the mixing chamber outlet is from 25 to 5000. A liquid-gas ejector having an area of the minimal cross-section of its mixing chamber calculated according to the above-mentioned formula exhibits an improved efficiency factor.
