The utility model discloses mainly be applied to crude benzol ethylene top of the tower heat recovery technical field, in particular to crude benzol ethylene top of tower heat reclamation device, including crude benzol ethylene tower, crude benzol ethylene top of the tower portion connects the overhead condenser, and the tube coupling compressor is passed through at the overhead condenser top, and tube coupling ethylbenzene / water azeotropy evaporimeter is passed through to the bottom, and top and the ethylbenzene recovery tower that crude benzol ethylene tower is connected respectively to the pipeline is passed through to the lower part of one side, and the compressor export sets up ethylbenzene / water azeotropic mixture vaporization pipeline through the one side on tube coupling ethylbenzene / water azeotropy evaporimeter upper portion, ethylbenzene / water azeotropy evaporimeter top, and the bottom sets up ethylbenzene / water azeotropic mixture pan feeding pipe. Thoroughly broken away from the compression ratio that traditional heat pump technique need improve the compressor greatly and could realize having saved investment and energy consumption for the difficult problem of bottoms material heating, made heat pump application of optimization enable.
