With increasingly stringent environmental regulations, traditional open-air spraying has been banned due to pollution problems, making retractable spray booths essential equipment in industrial spraying. It realizes clean production of spraying operations through scientific air flow design, multi-stage filtration system and advanced waste gas purification technology. The core working principles are as follows:
1. Intelligent Air Circulation System
The retractable spray booth adopts negative pressure air flow control technology. Fans generate stable downward air flow at the speed of 0.2~0.5 m/s to quickly guide paint mist and harmful gas to the treatment area and prevent ambient diffusion. The fully enclosed structure together with top vertical air curtain further isolates paint mist pollution and protects operators' health.
2. Multi-stage Filtration and Purification of Paint Mist
Primary filter layer intercepts large particulate dust such as metal scraps and fibers with a filtration efficiency above 85%.High-efficiency filter cotton captures paint mist particles larger than 4μm with a purification rate over 98%.The wet treatment module uses water curtain equipment to flush residual paint mist into circulating water tank, where paint slag automatically agglutinates and separates to greatly reduce solid waste discharge.
3. In-depth Treatment of VOCs Waste Gas
Volatile organic compounds generated during spraying are treated by RCO catalytic combustion or activated carbon adsorption.For catalytic combustion, VOCs are decomposed into carbon dioxide and water at low temperature of 200~400℃ with the help of catalyst, achieving purification efficiency no less than 95%.In activated carbon adsorption process, waste gas is purified up to standard after adsorption. Saturated carbon materials can be regenerated by high temperature desorption to cut operation and maintenance costs.
4. Energy Saving and Intelligent Control
Modern retractable spray booths are equipped with temperature control system and automatic monitoring modules.In baking mode, the hot air circulation system maintains constant temperature at 55~60℃, reducing energy consumption by 40%.It monitors VOCs concentration and equipment operating status in real time to ensure emissions comply with Integrated Emission Standard of Air Pollutants GB 16297.
