Circulating dechlorination reaction device

The utility model provides a circulating dechlorination reaction device. Relates to the field of dechlorination equipment, and aims to solve the problem that the current dechlorination equipment is difficult to meet the requirements of continuous wastewater treatment and convenient regeneration of a dechlorination agent, a reaction tube and a baffling channel are arranged in a tank body, and wastewater can react with the dechlorination agent in the reaction tube when flowing through the reaction tube, so that chloride ions in the wastewater are removed; comprising a tank body, partition plates, reaction tubes and baffle plates, the partition plates are installed in an inner cavity of the tank body, the partition plates sequentially divide the cavity into a first cavity, a second cavity and a third cavity, one end of each reaction tube is communicated with the first cavity, the other end of each reaction tube penetrates through the second cavity and then is communicated with the third cavity, and the at least
