Hydroxide removal system for removing acid gas absorbent

The utility model relates to a hydroxide removal system for removing an acid gas absorbent, which comprises a storage tank for storing the acid gas absorbent and a reaction tank for removing hydroxide in the acid gas absorbent, the storage tank is connected with a first circulating pump, the liquid inlet end of the first circulating pump is connected with the storage tank through a pipeline, and the liquid outlet end of the first circulating pump is connected with the reaction tank through a pipeline. The liquid outlet end of the first circulating pump is connected with the reaction tank through a pipeline; the reaction tank is connected with a feeding device for adding an acidic agent into the reaction tank, and a stirring device for stirring liquid in the reaction tank and a cooling device for cooling the reaction tank are also arranged in the reaction tank. The acid-base reaction device has the beneficial effects that the gas absorbent is introduced into the reaction tank to react with the acid medicament,
