Patent ID: 7059591

Claim:
Apparatus for producing a micro-dispersed gas-liquid mixture, comprising a cylindrical housing having a cylindrical surface with bottom and top covers, which in turn incorporate: a gas-liquid ejector unit consisting of said bottom cover of said cylindrical housing, a first part of said cylindrical surface of said housing, an inlet for gas connected to a gas injection line, an inlet nozzle for liquid connected to an injection liquid line and a first partition of said cylindrical housing, said inlet nozzle having has both outside and inner surfaces to adapt a conical orifice of said first partition to provide a required flow-rate of an ejected gas through said gas inlet; a cavitation unit communicating through said first partition with said gas-liquid ejector unit, said cavitation unit comprising said first partition, a second part of said cylindrical surface of said housing, a hollow cylindrical cavitation chamber having at least one tangential inlet allowing a gas-liquid mixture from said gas-liquid ejector unit to flow inside the hollow cylindrical cavitation chamber and a second partition having an orifice connected to said hollow cylindrical cavitation chamber; a jet dispersing unit communicating though said second partition orifice with said cavitation unit comprising said second partition, a third part of said cylindrical surface of said cylindrical housing, a hollow cylindrical dispersing chamber attached to said second partition, said top cover of said cylindrical housing and an outlet connected to an injection well, said hollow cylindrical dispersing chamber includes at least one outlet channel and a hollow dip at the bottom of said hollow cylindrical dispersing chamber, said outlet channel communicates with said outlet connected to said injection well.
