ARRANGEMENT FOR CLEANING VENTILATION AIR POLLUTED WITH PAINT PARTICLES

摘要

An arrangement for cleaning ventilation air coming from a spray booth (1) for painting e.g. car bodies (2), and polluted with paint particles comprises a duct (7) which is located downstream of the spray booth and in which means (8) for separating the paint particles of the ventilation air is so arranged as to be located immediately underneath the floor (5) of the spray booth (1). The means (8) consists of at least one discharge electrode (10) serving as ion source, and at least one movable gas-permeable collecting electrode (12). Further, the collecting electrode is arranged transversely of the direction of flow of the ventilation air through the duct (7).
