TREATING GAS FROM SPRAY BOOTH

摘要

A spray booth has an intermediate grating type floor (20) through which air is circulated. The air passes through a cleaning liquid nozzle (A) and entrains and atomises cleaning liquid derived from an overflow trough (30) with weirs (46,48). A spent air channel (24) is enclosed by a cover (28) located at least 20 cm from a flow off edge (28a) of the cover. The cover may itself form part of the washing-liquid feed device. A guide channel leads from weir (40) to the upper edge of a slot (34) forming the orifice of liquid nozzle (A). The cover (28) shields the working area of the booth from the noise generated by the nozzle (A).
