forced circulation vacuun wastewater evaporator

Name: Three effect Evaporation and crystallizer

Project: Potassium dihydrogen phosphate solutionsevaporation and crystallization

Evaporating Rate: 100-----30000kg(L)/h

Applicable range:

An evaporator is a industrial device to concentrate solutions, especially with heat sensitive components. The device is applicable for dairy products,pharmacy,glucose,starch,chemical industry,xylose,citric acid,ammonium sulfate,biological engineering,environmental engineering and waste liquid recovery and treatment,etc.

System components:

Composed of evaporators of various effects, separators or crystallizer of various effects, condenser, hot pressure pump,

sterilizer, heat preservation tube, vacuum and drainage system, materials converting pumps of various stages, branch cylinder,

operation platform, electric meter control cabinet, valve, pipe etc.

Equipment Characteristics:

The forced circulation evaporator is used to prevent scaling or crystallization caused by boiled products on the heating surface. Therefore, velocity of flow in the pipe must be big enough.

The circulating liquid is heated when passing the heat exchanger. Then part of material liquid evaporates when pressure drops in the separator, so that the liquid is cooled down to the boiling point temperature corresponding to this pressure. For the reason of circulating pump, operation of the evaporator basically has nothing to do with temperature difference. The recycling speed of material can be precisely adjusted. Set the evaporative velocity within definite range. In its application in the part of crystallization, the crystal can be separated from circulating crystallized slurry through adjusting the speed of circulating flow and adopting special design of separator.
