experiment example

[0059] The paint mist treatment equipment provided in the present invention includes three paint mist treatment stages.

[0060] The first treatment stage: inside the paint mist catalytic chamber 1 in the water curtain spray booth, the interior of the catalytic chamber 1 is provided with a filter 1.1, a wet filter 1.2, a dehydrator 1.3 and an activated carbon filter bag 1.4 in sequence along the airflow; the paint mist passes through first. The filter 1.1 is used for filtering, and the airflow passes through the space between the Venturi filter tube 1.1.2 and the casing 1.1.4 to form a space that can accommodate the paint mist, and the filtered paint mist forms a spiral in the space to precipitate a part of impurities. The preferred filter housing 1.1.4 can be stacked in two layers, and a two-layer space that can accommodate paint mist is formed between the two layers of Venturi filter tubes 1.1.2 and the two layers of housing 1.1.4, which can separate impurities from the filte...

Abstract

The invention discloses a fire resisting damper used for treating paint mist. The fire resisting damper comprises a body, shutters, rotating shafts and rotating shaft control valves. The rotating shafts are transversely arranged in the body at equal intervals. The shutters are fixed to the rotating shafts. The rotating shaft control valves are arranged at one ends of the rotating shafts and used for controlling the rotating shafts to move. The rotating shaft control valves are smoke control valves and/or temperature control valves. The rotating shafts are hollow pipes. Water inlet valves are arranged at the other ends of the rotating shafts. Water outlet holes are uniformly formed in the rotating shafts. The fire resisting damper has the advantages that when fires occur, the rotating shaft control valves control the rotating shafts to rotate, the rotating shafts drive the shutters to rotate to enable the fire resisting damper to be in a closed state as in the picture, airflow in a desorption bin or a catalyzing bin is cut off to enable the desorption bin or the catalyzing bin to be in closed space, the situation of combustible gas entering is reduced, and flames are prevented from entering the desorption bin at the same time; meanwhile, the water inlet valves are opened, and water enters or exits from the bin through the water outlet holes to achieve the extinguishment effect.

Description

technical field [0001] The invention belongs to the field of production tail gas treatment, in particular to a fire damper used for paint mist treatment. Background technique [0002] At present, the water curtain spray booth suitable for painting in furniture, aviation, automobile, ship, container, hardware and electrical appliances, and electronics industry is a wet treatment equipment. The front of the equipment is a water curtain plate, the top of the water curtain plate is an overflow tank, and the back of the water curtain plate It is a multi-stage water curtain filter. When spraying paint, the paint mist entering the spray booth first meets the water curtain and is washed into the water tank. The remaining paint mist is completely intercepted in the water when it passes through the multi-stage water curtain filter. The water in the water tank is lifted by the water pump to the overflow tank on the top of the water curtain and multi-stage water curtain filter, and ov...
