Paint spray booth with high-efficiency demisting ability

Abstract

The invention relates to a paint spray booth with a high-efficiency defogging capacity, which comprises a paint spray booth, the paint spray booth comprises a personnel operation chamber and a paint spray chamber which are sequentially connected, a water curtain plate is arranged on the wall surface of the paint spray chamber, a steam-water separation chamber is arranged in the paint spray chamber on the back of the water curtain plate, the steam-water separation chamber is connected with a deslagging chamber, an air feeder is arranged above the personnel operation chamber and the paint spray chamber, an induced draft fan is arranged above the steam-water separation chamber, a baseplate diversion structure and a main serration plate are arranged below the paint spray booth, the water curtain plate is arranged above the baseplate diversion structure, the main serration plate is fully fixedly arranged at the bottom end of the water curtain plate, the bottom end of the water curtain plate is provided with an arc lifting section, a diversion serration plate is arranged on the side wall of the water curtain plate at the upper end of the arc lifting section, the diversion serration plate integrally extends so as to form an arc diversion surface, and the steam-water separation chamber is connected with the deslagging chamber by a bottom pipeline. The paint spray booth disclosed by the invention is simple in structure, scientific and reasonable in design, low in cost, and high in paint fog capture efficiency, and effectively reduces the subsequent environmental processing load.

Description

technical field [0001] The invention belongs to the field of spray booths, in particular to a spray booth with high-efficiency defogging capability. Background technique [0002] The painting process in the automobile, furniture, packaging and other industries is one of the important process steps in industrial production. The painting is generally carried out in the spray booth. In order to meet the requirements of environmental protection, the excess spray paint will be captured by circulating water containing chemicals in the spray booth. , to realize the separation of VOC and 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 the vertical water curtain plate, and the water curtain formed on the surface of the vertical water curtain plate catches the excess of spray paint. paint mist, but the structure has limited capture ability and low capture ra...

[0002] The painting process in the automobile, furniture, packaging and other industries is one of the important process steps in industrial production. The painting is generally carried out in the spray booth. In order to meet the requirements of environmental protection, the excess spray paint will be captured by circulating water containing chemicals in the spray booth. , to realize the separation of VOC and 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 the vertical water curtain plate, and the water curtain formed on the surface of the vertical water curtain plate catches the excess of spray paint. paint mist, but the structure has limited capture ability and low capture rate. The reason is that the surface area of ​​the water curtain is small, and the capture rate is relatively low on the limited water curtain plate. The load in the environmental protection treatment of organic waste gas is relatively large. 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. Due to the existence of paint residue, directly discharged into the sewage treatment tank will bring huge processing load, processing difficulty
