GAS-LIQUID EJECTOR

摘要

The present invention pertains to the field of jet-generation techniques and essentially relates to a gas-liquid ejector which comprises a mixing chamber having a surface area at the smallest flow section determined by the mathematical relation (I) where F is the surface area at the smallest flow section of the mixing chamber, k is the design factor, Q is the volumetric flow-rate of the liquid medium through the nozzle, g is the acceleration of the gravity force, y is the density of the liquid medium fed into the nozzle and Pc is the pressure of the liquid medium at the nozzle inlet. The factor k has a value ranging from 1.6 to 60 when the ratio between the pressure of the liquid at the nozzle inlet and the pressure of the medium mixture at the outlet of the mixing chamber ranges from 1.4 to 25. The same factor k has a value ranging from 60 and 2200 when the ratio between the pressure of the liquid at the nozzle inlet and the pressure of the medium mixture at the outlet of the mixing chamber ranges from 25 to 5000. A gas-liquid ejector having a surface area at the smallest flow section calculated according to the above-mentioned mathematical relation exhibits an improve efficiency factor.
