Background technique

Spray booths are widely used in automobiles, furniture, packaging and other industries. In the process of painting, in order to meet the requirements of environmental protection, circulating water containing chemicals will be used to capture excess spray paint in the spray booth to achieve the separation of VOC and paint mist. To carry out effective environmental protection treatment, the structure used to capture paint mist in the existing paint spraying room mainly passes through the vertical water curtain plate, and uses circulating water to form a water curtain on the surface of the vertical water curtain plate to capture the excess paint mist of spray painting, but the capture ability of this structure is limited , the capture rate is low. The reason is that the surface area of the water curtain is small, and the capture rate on the limited water curtain plate is relatively low. Since the paint mist is carried out by the gas, the load in the subsequent environmental protection treatment of organic waste gas is relatively large. In addition, the bottom surface of the existing spray booth is flat, and the paint mist is captured by the chemical water to form paint slag, which will be deposited on the bottom surface of the spray booth after a long time, which is difficult to remove and takes time and effort.

The weak points of water unevenness and structural deformation under the pressure of strong winds in the room-level water curtain cloth simplify the support structure and manufacturing difficulty of the water curtain. The absence of longitudinal seams in the water curtain plate does not affect the horizontal uniform distribution of the water curtain.

2. The high-efficiency atomization and capture spray booth includes a spray booth, which includes a personnel operation room, a paint spray room, and a steam-water separation room connected in sequence. The inner wall of the spray booth is provided with a water curtain. The bottom surface of the room is a slope, and the lower end of the slope at the bottom of the spray booth is connected to the steam-water separation room through a double-atomized paint mist capture structure. A defogging wheel is set in the middle of the steam-water separation room. The excellent dynamic water surface overcomes the problem of accumulation of paint slag at the bottom of the tank in the long-term operation of the original spray booth.

The diversion section forms a spatial fit with the main sawtooth plate and the diversion sawtooth plate. The uncaptured paint mist enters from the first-level paint mist inlet and passes through the highest point of the arc surface lifting section, which is the second-level paint mist inlet. It is formed due to space extrusion. As the airflow changes, the chemical water is sucked into the second vortex atomization space by the airflow for more complete atomization, so as to better capture the remaining paint mist, and enter the gas mist separation port through the arc-shaped diversion surface, and the gas and the bottom plate diversion structure After contacting the extended bottom surface, it turns back and rises to enter the organic waste gas treatment system from the gas outlet, and the liquid part contacts with the extended bottom surface of the diversion structure, dissolves into the liquid on the bottom surface, and is discharged from the liquid outlet into the liquid treatment system.

5. The utility model adopts the overflow tank structure on the side of the water curtain above the main sawtooth plate to realize the uniform distribution of the liquid surface on the surface of the water curtain and better capture of paint mist. The front bottom surface of the protruding diversion section of the bottom plate diversion structure is The inclined surface can make the chemical water on the bottom surface flow, prevent the deposition of paint slag, and help the primary paint mist inlet to inhale and atomize the chemical water.

6. The utility model uses pins to install a diversion sawtooth plate on the side wall of the water curtain plate at the upper end of the arc surface section. The pins can facilitate the installation and disassembly of the diversion sawtooth plate, and the maintenance is more convenient and quick.

7. The utility model has the advantages of simple structure, scientific and reasonable design, low cost, high paint mist capture efficiency, and effectively reduces the subsequent environmental protection treatment load.
