experiment example

[0057] The paint mist treatment equipment provided in the present invention includes three paint mist treatment stages.

[0058] 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 for paint mist treatment. The fire resisting damper comprises a body, shutters, rotary shafts and rotary shaft control valves; the rotary shafts are transversely arranged inside the body at equal intervals; the shutters are fixed to the rotary shafts; the rotary shaft control valves are arranged at one ends of the rotary shafts and used for controlling movement of the rotary shafts; the rotary shaft control valves are smoke control valves and / or temperature control valves. The fire resisting damper for paint mist treatment has the beneficial effects that when a fire happens, the rotary shaft control valves control the rotary shafts to rotate, and the rotary shafts drive the shutters to rotate, so that the fire resisting damper is in a closed state as shown in the figure (a), airflow in a desorption bin or a catalytic bin is cut off, the desorption bin or the catalytic bin is made to be located in a closed space, flammable gas entering the bin is reduced, and meanwhile flames are prevented from entering the desorption bin.

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...
