APPARATUS FOR DEGASSING LIQUID Russian patent published in 1999 - IPC

FIELD: liquid degassing systems, possibly systems with hydraulic drive. SUBSTANCE: apparatus for degassing liquid includes housing with inlet and outlet branch pipes, acoustic irradiator in the form of toroidal elastic envelope apertured in its lower portion by radiant cutouts with formation of springy sectors. Envelope is joined with deflector and nozzle portion of inlet branch pipe having lengthwise different-length cuts and joined with inlet branch pipe by means of bellows. Deflector is cone one, it has additional spreading surface in the form of discs mutually secured with formation of inner cavity. Upper disc is apertured in its peripheral portion with formation of flow-through windows. EFFECT: increased degassing degree, vibration-acoustic treatment of liquid without special acoustic generators with additional power source, possibility of automatic control of optimal mode of degassing at changing liquid flowrate. 6 cl, 4 dwg
