Abstract (en)

[origin: EP0561351A1] In the case of known paint spray booths, the exhaust air is removed by means of venturi scrubbing installations arranged under said booths. Frequently occurring disruptions to the production flow caused by clogging, a high noise level and elaborate dirt separating installations, and also by deposits in the water feed pipes, have disadvantageous effects. The novel arrangement is intended to reduce considerably or even eliminate the disadvantages mentioned. For this purpose, underneath sloping trickle plates (3, 3', 4, 5) of the venturi scrubbing installation there are arranged specifically the scrubbing nozzle (11) vertically, the scrubbing nozzle itself (11) and a following system of knocking-down bars (12) off-centrally and an exhaust air duct (15) is conducted inside the basic dimensions of the paint spray booth. The bottom plate (B) of the water distributer channel (R) runs over its entire length at a slope to the plates of the scrubber (W) and directly joins the bottom pan (BW), forming a water through-flow gap (SP) with respect to the neighbouring channel side (RS1). The circulating water feed pipes (ZR) open out in the head region (RK) of the channel (R) into the latter and arranged in the region between the feed pipes (ZR) and the water through-flow gap (SP) are baffle plates or distributor plates (VT) for making the water flow more uniform. <IMAGE>
