Evaporator
Evaporator

       The evaporator manufactured by our company is mainly tubular falling film evaporator, which is used for evaporation of caustic soda of 32%-73%. The heating fluid is steam, and the materials are pure nickel, 316L, 310S, etc.

       The evaporator is the key equipment for the evaporation of solid caustic soda which is consisted of heating chamber and evaporation chamber. The lye enters through the top of the chamber, then enters into the heat exchange tubes through the film maker to form a film, and gradually increases lye concentration in the process of heat exchange with steam. The lye enters the evaporation chamber, and the secondary vapour generated by the increase of concentration enters the secondary pipeline through the demister, while the lye discharges from the bottom of the evaporation chamber. In order to ensure the uniformity of alkali film formation in heat exchange tubes, the equipment adopts three-layer self-conducting film technology (patent) to improve the film formation effect.
