Evaporators are classified into three types based on operating pressure: atmospheric, pressurized, and vacuum. Based on the movement of the solution in the evaporator, there are: ① Circulating type. The boiling solution passes multiple times through the heating surface in the heating chamber, such as in central circulation tubular, suspended basket, external heating, Levene, and forced circulation types. ②One-way type. In the heating chamber, the boiling solution passes through the heating surface once only, without circulating; the concentrated liquid is then discharged, as in cases such as rising-film, falling-film, stirred-film, and centrifugal-film processes. ③Direct contact type. The heating medium is in direct contact with the solution for heat transfer, such as in submersion combustion evaporators. During operation, evaporation units consume a large amount of heating steam. To save this steam, multi-effect evaporation units and steam recompression evaporators can be used. Evaporators are widely used in industries such as chemicals and light industry.

Have you used it? What is it used for? Is it about dealing with wastewater? Special equipment for the evaporation and concentration of fermented liquid, as well as high-concentration organic or chemical wastewater. It has advantages such as energy efficiency, short heating time, suitability for evaporating and concentrating materials with high viscosity, and a high concentration ratio; it also enables the production of high-quality deionized water to meet the needs of industrial boilers. And they can be combined to form two-effect, three-effect, four-effect, and five-effect evaporation systems. It is also possible to use the waste steam at the top of tube bundles or tray dryers, as well as other heat sources with low calorific value (such as condensed water vapor), as heat sources for evaporators, thereby turning them into waste-heat evaporators. This approach can significantly reduce the amount of steam required, achieving the greatest energy-saving effects. When there is an adequate supply of waste heat steam, raw steam can be completely eliminated, resulting in significant economic benefits. Working principle: The material is evenly distributed into each evaporator tube via a distributor. Under the influence of gravity and the secondary steam generated by self-evaporation, the material forms a spiral film that flows from top to bottom; at the same time, heat exchange occurs between this material film and the steam on the outer wall of the tubes, causing the water in the material to evaporate. A stable temperature difference and heat transfer area ensure a consistent rate of water evaporation. The secondary steam produced by the evaporated water is reused multiple times, thereby making maximum use of thermal energy and reducing steam consumption – this is the design principle behind multiple evaporation stages.
