Where is the customized OSLO evaporation crystallizer mainly used? The extraction of industrial production raw materials is mostly obtained by evaporation crystallization process or freeze crystallization process. In order to obtain higher quality, raw materials with uniform concentration, dryness and particle size, various types of crystallizer equipment are required. Customized OSLO evaporation crystallizer is one of them.
1. The basic components of the equipment
Customized OSLO evaporation crystallizer is generally regarded as a complete set of devices, not only OSLO crystallizer components, but its components include heat exchanger, crystallization separation chamber, condenser, circulating pump set, vacuum pump, control system and so on.
2. The flow direction of the solution in OSLO
The customized OSLO evaporation crystallizer is a mother liquor type circulating equipment. The circulating mother liquor is heated by a heater and then enters the evaporation separation chamber for evaporation. After the solution reaches the saturated concentration, the crystal liquid enters the suspension bed through the vertical pipe in the evaporation separation chamber. Crystals can grow into full grains. During the crystallization process, the ascending mother liquor in the OSLO has the effect of elutriation and classification on the crystals, the crystals with large particles descend, and the crystals with small particles float up.
3. Application areas
The customized OSLO evaporation crystallizer with crystal particle classification function is more used to produce large particle products. It has a clarifying area with a larger diameter. After eliminating the supersaturation, it is directly sucked away by the pump group, which reduces the probability of secondary nucleation and is more conducive to For cultivating large-particle crystals, the equipment can also complete continuous production, flexibly control the output size, and have the characteristics of low labor intensity. It is widely used in low temperature freezing crystallization projects with low viscosity of mother liquor such as sodium sulfate decahydrate, ammonium chloride, sodium nitrate, persulfate, carbonate and oxalate.
