Title: Demister for paint spray booths - having irrigated wall followed by rising entrainment pipes to centrifugal separator
Inventor: HERING MANFRED
IPC: B05B14/46
Filed: 1975-12-05
Abstract: Device for wet washing of the exhaust air from a spray broth contg. paint mist involves pulling the air up a rising tube with entrained water droplets. A centrifugal fan unit at the top is used for this. The droplets of paint coagulate in the lower press. space to form a mixt. with the water. The mixt. then flows down the booth wall. The low press. spare is a horizontal tangential separator into which the rising tubes feed tangentially. The inlet end of the fan is mounted at one end of the separator. It consists of a sheet vessel of cylindrical shape with a conical reducer between it and the fan inlet. Device is for use with paint spray booths to prevent atmospheric pollution. The problem with existing wet cleaners is that either they require large contact chambers with significant draught or they give inadequate scrubbing. Large chambers require walls of considerable rigidity to withstand the differential pressure on them. The system claimed allows good separation in a relatively small contact space.
