In the painting process of large-scale telescopic mobile spray booths, waste gas is inevitably generated, which not only pollutes the environment but also harms human health. Therefore, it is crucial to treat this waste gas. The main methods for waste gas treatment in spray booths include: water spraying method, combustion method, absorption method, condensation method, plasma low-temperature catalytic oxidation method, and adsorption method. Among them, the most commonly used are the water spraying method and the adsorption method.

Among them, water spraying and adsorption are the most commonly used methods.
Today, the mobile spray booth manufacturer will introduce the adsorption method through Large-scale retractable mobile spray booth waste gas treatment methods. Taking the automotive spray booth as an example, this is because the waste gas generated by the automotive spray booth is quite special.
This waste gas is a type of spray paint waste gas, mainly composed of two parts: liquid paint mist and gaseous VOCs. For liquid paint mist, a device for removing paint mist is needed. However, for insoluble water volatile organic compounds, the mature industrial technology should still be an "activated carbon adsorption desorption device".
Large-scale retractable mobile spray booth Activated carbon adsorption is a common waste gas treatment method. The adsorption method uses porous activated carbon, silicon bath soil, smokeless coal, etc., to adsorb organic gas molecules onto the surface to purify them. Advantages of activated carbon adsorption desorption device: high purification rate (up to 99% activated carbon adsorption), practicality, simple operation, and low investment. Disadvantages: large system wind pressure loss, high energy consumption, difficult to grasp the adsorption agent saturation point, limited adsorption agent capacity, and large operating volume. Activated carbon is a very good adsorbent. It uses charcoal, various nut shells, and high-quality coal as raw materials. It uses physical and chemical methods to crush, screen, activate catalysts, rinse, dry, and screen raw materials, and is manufactured through a series of processes.
