Circulating type deodorization system

The utility model discloses a circulating deodorization system and belongs to the technical field of deodorization devices. Comprising a tower body, a gas storage disc is arranged in the tower body, a plurality of vertical pipes are arranged at the top of the gas storage disc, a plurality of gas outlet discs are arranged on the circumferential outer walls of the vertical pipes, and a plurality of gas outlet holes are formed in the tops of the gas outlet discs. The vertical pipe with the gas outlet disc is arranged on the gas storage disc and is matched with the activated carbon filling block to adsorb odor and then is matched with the deodorization liquid to spray, so that the odor in gas is removed, and the problem that a common deodorization system is poor in deodorization effect due to the fact that a simple structure is used is solved; the deodorization capability of the deodorization system is improved; by arranging the U-shaped pipe and the liquid storage tank which are communicated with the mixing tank
