Abstract
The present invention pertains to the field of jet technology and essentially relates to a multi-nozzle liquid-gas ejector having nozzles and mixing chambers placed in alignment to each of the nozzles. The distance between the outlet section of each nozzle and the inlet section of the appropriate corresponding mixing chamber is determined from the following formula: where L—distance between the outlet section of the nozzle and the inlet section of the corresponding mixing chambers; k—design factor ranging from 0.001 to 0.3; Fc area of the minimal cross-section of the nozzle; Fk area of the minimal cross-section of the mixing chamber; P—liquid pressure at the nozzle inlet; g—acceleration of gravity; &ggr;—density of the liquid fed into the nozzle.
