The operation process of a water curtain painting booth:

The water curtain paint spray booth intercepts the paint mist-laden air for the first time after passing through the water curtain, then enters the "boiling mixing channel." As the airflow sweeps over the water surface below the channel, the high-speed action lifts the water into the channel. When the airflow reaches the top of the channel and the speed decreases, some of the lifted water falls back due to gravity, creating a collision with the water that continues to be lifted, forming a boiling effect. The water droplets in this boiling state are thoroughly mixed with the airflow, ensuring that particles are completely washed into the water, achieving the goal of cleaning and purifying the paint mist particles.

Part of the water mentioned is carried by the air flow into the air collection box, where it is separated from the air through a分流格栅. The purified air is then exhausted outdoors by the exhaust fan, while the separated water settles at the bottom of the collection box, collects in the overflow channel, and overflows onto the water curtain panel to form a recirculating water curtain, effectively removing paint mist particles from the air and providing the operators with a clean working environment.

In environments with high benzene-based paint mist, it is recommended to use an activated carbon purifier in conjunction for filtration. Multiple adsorptions are required to achieve purification. Paint mist particle purification efficiency: ≥98%.

■ Regularly adding a specialized paint mist flocculant to the water tank will cause the paint mist particles in the water to coagulate into sludge and float to the surface, making them easy to retrieve. This also helps alter the adhesion of the paint mist, preventing sludge from adhering to the interior of the equipment, thereby reducing maintenance work. The water curtain paint booth is widely used in industries such as machinery, automotive, aviation, aerospace, rail, electrical motors, pumps, machine tools, furniture, and more for the painting of complete machines or components.
