Method of and apparatus for separating liquid from solids entrained therein

摘要

The invention relates to a method of and apparatus for separating liquid from solids entrained therein, which solids, preferably paint particles emanating from a paint spray booth are capable of floating on the liquid. The liquid and solids are entrained in a collector which is open to atmosphere and in which a Coanda - type flow prevails so that the solids are collected as a skin on the surface of the liquid. In one embodiment the level of the liquid is raised so that the skin slips over a lip and out of the collector, leaving the liquid behind; in another embodiment the skin is collected behind a restraining device which is moved to allow the skin to flow through an outlet therefor, again leaving the liquid behind.
