This invention discloses a leather processing waste gas adsorption and purification device, belonging to the field of industrial waste gas treatment technology. The device includes a purification chamber, an exhaust fan, an inlet pipe, an outlet pipe, a clamping assembly, an activated carbon group, a receiving cavity, an outlet branch pipe, an inlet branch pipe, and an exhaust branch pipe. Because the diameter of the outlet pipe is smaller than that of the inlet pipe, the waste gas entering through the inlet pipe cannot be completely discharged through the outlet pipe. As a result, the air enters the interior of the outlet branch pipe through the receiving cavity, then enters the interior of the inlet branch pipe and contacts the activated carbon group again for purification and adsorption. Subsequently, it enters the interior of the outlet pipe through the exhaust branch pipe and is discharged outward. The waste gas discharged directly through the outlet pipe can undergo two adsorptions and purifications by the activated carbon groups on both sides, thereby increasing the residence time of the waste gas. Furthermore, waste gases from different paths can undergo two adsorptions and purifications by the activated carbon groups, resulting in better adsorption and purification effects.
