For the current catalytic combustion exhaust gas treatment, the shell ends are designed as connection points, featuring an inlet and outlet. Inside the shell, there's an activated carbon filter chamber, a plasma chamber, and a photocatalytic chamber. These are connected to an adjusting device on the side of the connection points. The activated carbon filter chamber is welded with baffles, while the activated carbon filter unit is connected to the filter chamber. The plasma generator is installed within the plasma chamber, and the equipment is placed in the photocatalytic chamber. The baffles are welded to the stainless steel filter chamber's plates, and the stainless steel filter unit is installed within the filter chamber. Currently, the system boasts excellent exhaust gas purification and filtering effects.
