This invention proposes an activated carbon wet desulfurization device, belonging to the field of wet desulfurization technology. It solves the problems of high operating costs, easy scaling, and difficult byproduct disposal in traditional wet desulfurization devices. The device comprises a box-type structure, including a shell with a horizontally arranged dividing wall plate inside, dividing the interior into upper and lower regions. The lower region is the primary desulfurization zone, and the upper region is the secondary desulfurization zone. An inlet pipe is inserted into the inlet pipe interface. A primary activated carbon assembly is installed in the primary desulfurization zone, located above the inlet pipe. A primary hanger is installed at the lower part of the dividing wall plate, connected to a primary spray pipe. A secondary activated carbon assembly is installed in the secondary desulfurization zone. A secondary hanger is installed on the inner wall of the top of the shell, connected to a secondary spray pipe. An outlet pipe is located at the top of the shell, communicating with the secondary desulfurization zone. It is mainly used for activated carbon wet desulfurization of acidic gases.
