Working solution regeneration tower

A working solution regeneration tower relates to the technical field of material detection equipment and comprises a tower body, a catalyst bed arranged in the tower body, a catalyst arranged in the catalyst bed, a working solution inlet arranged at the bottom of the tower body, a working solution outlet arranged at the top of the tower body, a steam inlet arranged on the side wall of the tower body, a steam pipe arranged in the steam inlet and extending into the catalyst bed. The steam pipe is communicated with a gas distribution pipe, the gas distribution pipe is laid in the catalyst bed, and gas distribution holes are formed in the gas distribution pipe. According to the utility model, the gas distribution pipe is laid inside the catalyst bed, the steam is introduced into the catalyst bed, the catalyst is purged by the steam, and the catalyst is purged from the inside, so that the contact area between the steam and the catalyst is enlarged, and the purge effect of the catalyst is improved. 一种工作液再生塔，涉及物料检测设
