The utility model provides a deacidification device in a chlorobenzene preparation process, and belongs to the technical field of chlorobenzene preparation. The deacidification device in the chlorobenzene preparation process comprises a tower body, double layers of fillers are arranged in the tower body, a gas phase circulation port is formed in the tower body and used for being externally connected with a tower kettle reboiler, a distributor is arranged above each filler, and chlorobenzene raw materials enter the tower body through the distributors above. In the application, a chlorobenzene raw material is uniformly sprayed onto the filler through the distributor, and high-temperature steam entering from the gas-phase circulation port and the chlorobenzene raw material covering the filler are subjected to heat transfer, so that hydrogen chloride gas dissolved in the chlorobenzene raw material is volatilized; and meanwhile, steam generated by vaporization of the material is used as a medium to blow off the di
