Continuous Evaporation Crystallizer

Crystal slurry circulating continuous crystallizer. During operation liquid from the lower circulation pipe to join and leave the crystal room at the bottom of the crystal slurry mixture sent to the heating chamber by the pump. Crystal slurry temperature in heating room (usually 2~6°C), but evaporation dose not occur. Hot plasma into the Crystal Room Crystal after boiling, the solution had reached saturation,so part of the solute in the suspened sediment grain surface,the crystals grow. As the product of the crystal slurry discharged from the upper circular tube.Although forced circulation evaporation crystallizers have high production capacity, the particle size distribution of the product is relatively wide.

DTB Evaporator Crystallizer

The draft tube-mold baffle evaporation. but also a crystal slurry circulating mold Elutriation device then there is the lower column, the device features a draft  tube and the cylindrical baffle, operation,saturated liquid heat circulation  pipe added to the lower part of a continuous, circular tube with a small crystal mother liquor entrained mixture pumped to the heater. The heating of the solution near the bottom of the draft tube into the mold by slowly rotating propellers sent along the draft tube surface. Solution in the liquid cooling, up to over saturation,some of which solute particles in the suspension deposited on the surface, so that the crystal growth.  Outside the ring bezel and a Settlement area. Settlement of large particles in the settlement area, while the small particles into the circulation pipe is with the mother liquor and heated to dissolve. Crystal at the bottom of the mold into the elutriation column. To crystallize the product size as even as possible part of the settlement area to the mother liquor added to the bottom of the elutiation column.the use of hydraulic grade effect in that the return flow of small particles with the mold, and mold products discharged from the lower part of elutriation column Out.
