EJECTOR AND METHOD OF ITS OPERATION

摘要

FIELD: liquid and gas ejectors; processes pertaining to contact of gases with liquids. SUBSTANCE: proposed ejector has cylindrical receiving chamber with gas supply branch pipe and liquid supply tube mounted along axis of chamber; said tube is provided with multi-nozzle attachment at outlet; ejector is also provided with contraction, mixing chamber and diffuser. Provision is made for optimal geometric and gas-dynamic parameters. Proposed method includes delivery of liquid under pressure ensuring required rate of delivery which exceeds sound velocity in two-phase mixture by at least 25% at maintenance of mass ratio of gas medium and liquid not exceeding 0.01. Proposed supersonic liquid-and-gas ejector ensures supersonic flow of gas and liquid through shock-wave zones and mixing of liquid and gas at submicron level. EFFECT: enhanced efficiency. 10 cl, 5 dwg
