含有低浓度VOCs的废气通过蜂窝状沸石时，VOCs成分被吸附在沸石中，净化后的气体排放***大气中，或排放***室内进行循环处理，通过循环处理，回收热能。此时，已吸附VOCs的蜂窝沸石连续旋转，利用少量的加热空气在解吸附模块进行吸附再生，此过程中，能够从低浓度的废气中得到高浓缩气体。

When the exhaust gas containing low concentration VOCs passes through the honeycomb-shaped zeolite, the VOCs component is adsorbed in the zeolite, and the purified gas is discharged into the atmosphere, discharged into the room for circulation treatment, and recycled to recover the heat energy. At this time, the honeycomb zeolite adsorbed with VOCs is continuously rotated and adsorbed and regenerated by a small amount of heated air in the desorption module, and a highly concentrated gas can be obtained from the low concentration
