The utility model provides an evaporative condensing unit, which comprises a material storage tank, a film evaporator, a high-fraction storage tank and a low-fraction storage tank. A liquid discharging port of the film evaporator is connected with the high-fraction storage tank, a heat exchanger is arranged between the material storage tank and the film evaporator, the material storage tank is connected with a feeding port of the heat exchanger, a discharging port of the heat exchanger is connected with a feeding port of the film evaporator, a gas discharging port of the film evaporator is connected with a gas inlet of the heat exchanger, and a gas outlet of the heat exchanger is connected with the low-fraction storage tank. The evaporative condensing unit has the advantages that heat of high-temperature low-fraction materials discharged from the film evaporator is made full use of, materials needing evaporation are preheated, the material evaporating cost of the film evaporator is reduced, the condensing cos
