Product overview

Adsorption concentration unit is a new generation of VOCs treatment equipment independently developed by Huashijie. It is a method that organically combines the adsorption concentration unit and the thermal oxidation unit. It is mainly aimed at the organic waste gas with large air volume and low concentration. After adsorption purification and desorption, it is converted into organic waste gas with small air volume and high concentration for thermal oxidation treatment, and the heat released by organic matter combustion is effectively utilized.
