Falling film evaporator range

It is widely used in the evaporation, concentration and concentration of water or organic solvent solutions in the pharmaceutical, food, chemical, light industry and other industries, and can be widely used in the waste liquid treatment of the above industries. Especially suitable for heat sensitive materials, the equipment is continuously operated under vacuum and low temperature conditions, with high evaporation capacity, energy saving, low operating cost, and can ensure the material is invariable during evaporation.

Falling film evaporator works

Falling film evaporation is to add the liquid to the upper tube of the heating chamber of the falling film evaporator. Through the liquid distribution and film forming device, it is evenly distributed into the heat exchange tubes. Under the action of gravity and vacuum induction and air flow, it forms a uniform film. Flow from top to bottom. During the flow, it is heated and vaporized by the shell-side heating medium, and the generated steam and the liquid phase enter the separation chamber of the evaporator. The vapor-liquid is sufficiently separated, and the steam enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator. The medium is heated to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber.https://www.heczb.com/
