Abstract
A method of eliminating liquid foam appearing on the surface of a liquid tent in a reaction vessel is characterized by employing a liquid particle diffusion device with a liquid ejecting nozzle element and a liquid diffusing element for radially diffusing the liquid circulated from the reaction vessel in the form of liquid particles having kinetic energy. The liquid particles hit and break the foam thereby eliminating the foam.
Claims6
A method of eliminating foam appearing on a surface of a fixed amount of liquid content received within a reaction vessel which retains a free inner space left above said surface of said liquid content comprising:
- locating a liquid ejecting nozzle member and a subsequent diffusing member at a position within said free inner space of said reaction vessel and away from said surface of said liquid content, said diffusing member being spaced at a preselected distance from said nozzle member such that the liquid particles ejected at a wide angle from said nozzle member impinge upon said diffusing member;
- retracting a partial amount of said liquid content from said vessel through a conduit means;
- sending said partial amount of said liquid content to said liquid ejecting nozzle member through a second conduit means under a predetermined pressure exerted by a liquid pumping means, and;
- diffusing said partial amount of said liquid content through said diffusing member in the form of said liquid particles having therein kinetic energy against said foam thereby causing said foam on said surface of said liquid content to collapse and vanish.
