Product Description
aluminum sulphate evaporator the traditional method use single reactor to evaporate at atmospheric pressure. the new method is to use tri-effect countcurrent forced circulation evaporator,the operation temperature must higher than 120 degree and the material must use titanium. Forced circulation type evaporative crystallizer it is a kind of crystal mush circulation type continuous crystallizer. during the operation, the feed liquid is fed from the bottom of the circulating tube. after mixed with crystal mush that has left the bottom of the crystallizing chamber, it is sent to the heating chamber by the pump. when crystal mush is heated (generally 2~6) in the heating chamber, no evaporation occurs. the hot crystal mush will boil after it enters the crystallizing chamber, so that the solution reaches the status of supersaturation. then some solute will deposit on the surface of suspended crystal grains to make the crystal grow. the crystal mush as a product is discharged from the top of the circulating tube. the forced circulation type evaporative crystallizer has high production capacity, but the granularity distribution of products is wider.
