Description

Technical Field

[0001] The utility model relates to the technical field of thin film evaporators, in particular to a thin film evaporator heating device. Background Art

[0002] Thin film evaporator is a type of evaporator, characterized by the material liquid flowing in a film-like manner along the heating tube wall to transfer heat and evaporate. The advantages are high heat transfer efficiency, fast evaporation speed, and short material residence time. Therefore, it is particularly suitable for the evaporation of heat-sensitive substances. The thin film evaporator unit consists of three parts: evaporator, vapor-liquid separator, preheater and a simple separator. The evaporator is a rising film shell and tube heat exchanger. The evaporator has the characteristics of large production capacity, high efficiency, and short material heating time. It is suitable for the concentration of dilute solutions in the pharmaceutical, food, chemical and other industries;
