Introduction

        Falling film evaporation is to add the material liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into the heat exchange tubes through the liquid distribution and film forming device. Under the action of gravity, vacuum induction and air flow, it becomes a uniform film. Flow from top to bottom. During the flow process, it is heated and vaporized by the heating medium in the shell side, and the generated vapor and liquid phase enter the separation chamber of the evaporator together. After the vapor and liquid are fully separated, the vapor enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator as Heat the medium to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber

Equipment composition

   Each effect heating evaporator, each effect separator, condenser, heat pressure pump, sterilizer, insulation pipe, vacuum system, each effect material liquid transfer pump, condensate drainage pump, operating platform, electrical instrument control cabinet and valves, pipelines And other system composition.

Scope of application

        Falling film evaporators are widely used in the evaporation and concentration of water or organic solvent solutions in medicine, food, chemical, light industry and other industries, and can be widely used in waste liquid treatment in the above industries. It is especially suitable for heat-sensitive materials. The equipment is continuously operated under vacuum and low temperature conditions. It has high evaporation capacity, energy saving and consumption reduction, low operating costs, and can ensure the invariance of materials during the evaporation process.
