Heat recovery device for producing methyl ethyl carbonate by transesterification method

The utility model relates to a heat recovery device for producing methyl ethyl carbonate by a transesterification method. The heat recovery device comprises an outer tank body, and a premixing tank, a conveying pipeline, a reaction tank and a discharging pipeline which are arranged in the outer tank body and are sequentially connected from top to bottom, and the section, positioned between the reaction tank and the outer tank body, of the discharge pipeline is a first heat exchange pipeline. When materials which are subjected to ester exchange reaction in the reaction tank are discharged, heat energy in the reaction tank is recovered by adopting a mode that the reaction tank, the rotating shaft, the heat-conducting plate, the heat-conducting seat and the premixing tank are sequentially subjected to heat transfer, and heat energy of reaction products is recovered by adopting a mode that cooling liquid exchanges heat with the first heat exchange pipeline and the cooling liquid is heated; the heat energy is util
