VACUUM DEGASIFIER Russian patent published in 1995 - IPC

FIELD: suspensions and emulsion vacuum degassing. SUBSTANCE: vacuum degasifier has cylindrical body with collecting pipeline, gas removing branch pipe, located inside body gas separation joint made in the form of set of conical disks, branch pipe to remove liquid medium or solution, purified from gas with valve joint and pumping out pump. Valve joint is made in the form of floating hollow member with transfer holes in its lower part, that is coaxially mounted on collecting pipeline with capability of axial motion. Gas removing branch pipe is located under lower conical plate of gas separation joint. Pumping out pump is made as injection vacuum pump connected to branch pipe of gas removal. In the case both pumps have common drive. Degasifier provides increase of degassing effectiveness and operational reliability, automated maintaining vacuum value at inlet in working chamber and level of solution in it, decrease of mass and dimensions of apparatus, simplification of its structure. EFFECT: increased degassing effectiveness and operational reliability. 1 dwg
