Description

Technical Field

[0001] The utility model belongs to the technical field of evaporators, and in particular relates to a liquid film forced induction energy-saving evaporator. Background Art

[0002] Liquid film evaporator is a long vertical tube evaporator. It consists of a number of long heating tubes to form a heating chamber and a separation chamber with a large heat transfer surface. The liquid level of the evaporator is kept very low, generally accounting for 1 / 5-1 / 4 of the tube length. When the solution boils in the tube, it is mainly heated by secondary steam to form foam in the solution, and at the same time, a suction effect is generated, so that the solution forms a film on the tube wall and rises or falls rapidly. The center of the tube is the steam that rises or falls continuously.

[0003] In the existing evaporator, materials cannot be dispersed well after being transported into the evaporator during operation. Materials are easily piled up, and it is difficult for the accumulated materials to quickly evaporate the internal moisture, thereby reducing the operating efficiency. In addition, there is no effective deodorization mechanism when the moisture is evaporated and discharged, and the odor in the gas will be directly discharged, affecting the working environment.
