description The utility model provides a desorption tower for producing 4, 4-dichloromethyl biphenyl, which relates to the technical field of desorption towers and comprises a desorption tower body, and an oil inlet and an exhaust port are arranged at the top of the desorption tower body; an oil outlet and a steam inlet are formed in the bottom of the desorption tower body; an oil distribution device, a first filler layer, a heating device and a second filler layer are sequentially arranged in the desorption tower body from top to bottom. Through the arrangement of the oil distribution device, rich oil enters the desorption tower body, is dispersed and sprayed on the packing layer, and is in countercurrent full contact with high-temperature steam passing through the tower from bottom to top on the packing layer; the heating device heats the tower body from the inner part and the outer part of the tower body, so that the temperature in the desorption tower body is further ensured. And the analysis efficiency is high and t
