Tower top condenser for producing dimethylacetamide

The utility model discloses an overhead condenser for dimethylacetamide production, which comprises a tower body and a plurality of groups of condenser pipes arranged in an inner cavity of the tower body, the plurality of groups of condenser pipes are circumferentially distributed in the tower body by taking the central point of the tower body as a circle center, and the top of the tower body is fixedly connected with a plurality of groups of connecting pipes corresponding to the condenser pipes. The tower top condenser solves the problems that in the long-term use process of the tower top condenser, dimethylacetamide is prone to scaling on the inner walls of the tube nests, scaling on the inner walls of the tube nests is difficult to thoroughly remove in a washing mode, on one hand, the heat exchange efficiency of the tube nests is seriously affected, and on the other hand, the heat exchange efficiency of the tube nests is greatly improved. The problems that on the other hand, tube cracking is caused due to
