AI Technical Summary
Existing activated carbon adsorption devices require the activated carbon to be removed during desorption, which is inconvenient, and the waste gas only flows through one adsorption layer, resulting in poor adsorption effect.
A multi-layer activated carbon adsorption layer structure was designed, with multiple channels formed by baffles and deflectors inside the shell, allowing the exhaust gas to pass through the multi-layer adsorption layer in sequence. Desorption inlet and outlet are set at the bottom of the shell, and online desorption is performed using heated gas.
It enables desorption treatment without removing activated carbon, improving work efficiency, and significantly enhances the purification effect of waste gas through multi-layer adsorption.
