Design scheme：

The waste gas containing VOCs undergoes pre-treatment to remove large particles and harmful substances to the zeolite wheel, and then enters the zeolite wheel concentration device. After the VOCs components are adsorbed by the zeolite, they are discharged into the atmosphere up to standard. The desorption fan draws a portion of the exhaust gas from the runner to the desorption section, during which it exchanges heat with the hot gas from the heat exchanger. The temperature reaches 150-180 ℃, and VOCs are desorbed from the zeolite runner. They then enter the RTO device, where they are heated to above 800 ℃, oxidized to CO2 and H2O, and discharged into the atmosphere.

Acceptance status：

The project began operation in March 2019, during which the purification effect was very good. After third-party testing, the concentration of VOCs was 5.72mg/m 3， The removal efficiency is above 98.5%, far lower than the emission standard of volatile organic compounds in the surface coating industry in Shandong Province.
