Purified spray booth

Abstract

The invention relates to a paint spraying room allowing purification. The paint spraying room comprises a paint spraying room body. The paint spraying room body comprises a personnel operation shop, a paint spraying shop, a steam and water separation shop and a paint slag purifying shop. A water screen plate is arranged on the inner wall of the paint spraying shop, the bottom face of the paint spraying shop is an inclined face, the lower end of the inclined face at the bottom of the paint spraying shop is communicated with the steam and water separation shop through a double atomizing paint mist catching structure, the steam and water separation shop is connected with the paint slag purifying shop through a pipeline, and a mist removing wheel is arranged in the middle of the steam and water separation shop. The paint spraying room is simple in structure, scientific and reasonable in design, low in cost, high in paint mist catching efficiency and capable of effectively reducing the follow-up environment protection load.

Description

technical field [0001] The invention belongs to the field of spray paint booths, in particular to a paint spray booth capable of purification treatment. Background technique [0002] The spray booth is widely used, and the main fields include automobile, furniture, packaging and other industries. Various parts are sprayed in the spray booth, and the formed paint mist and volatile industrial organic pollutants need follow-up procedures. In order to meet the requirements of environmental protection, In the spray booth, circulating water containing chemicals will be used to capture excess spray paint to separate VOC from paint mist, so as to carry out effective environmental protection treatment respectively. The structure used to capture paint mist in the existing spray booth is mainly through vertical water curtains , the water curtain is formed on the surface of the vertical water curtain to catch the excess paint mist of spray paint, but the structure has limited capture ab...

[0002] The spray booth is widely used, and the main fields include automobile, furniture, packaging and other industries. Various parts are sprayed in the spray booth, and the formed paint mist and volatile industrial organic pollutants need follow-up procedures. In order to meet the requirements of environmental protection, In the spray booth, circulating water containing chemicals will be used to capture excess spray paint to separate VOC from paint mist, so as to carry out effective environmental protection treatment respectively. The structure used to capture paint mist in the existing spray booth is mainly through vertical water curtains , the water curtain is formed on the surface of the vertical water curtain to catch the excess paint mist of spray paint, but the structure has limited capture ability and the capture rate is low. The rate is relatively low, because the paint mist is brought into the subsequent organic waste gas environmental protection treatment unit by the gas, resulting in an increase in its operating load. In addition, the chemical water that has captured the paint mist in the prior art is directly collected into the sewage treatment tank for treatment. The existence of paint slag, directly discharged into the sewage treatment tank will bring a huge processing load to the sewage treatment tank, and the treatment is difficult
