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.
Falling Film Tube
Falling Film Tube
The single tubular falling film tube manufactured by our company is specially used for heat exchange of caustic soda under high concentration. The concentration of NaOH can reach 99.3%. This product is used to concentrate lye, mainly composed of inner and outer double-layer tubes. The lye enters the inner wall of the inner tube from the top of the falling film tube, and the high temperature molten salt enters the inner wall of the outer tube from the bottom of the falling film tube. The concentration of lye is further increased by heat exchange. In order to improve the service life of falling film tube in high temperature and strong alkali environment, the material used for contacting with alkali is Military Grade N4.
