Hallmark
It is the region of supersaturation and crystal growth area respectively in two places of the crystallizer, the crystals are fluidized and suspended in the circulating mother liquor for the crystal graded clear liquid circulation type: the main thing is to control the circulating pump pumping is basically crystal-free clear solution, and then transported to the heater to go to the cooling and warming up, and the supersaturation in the circulating mother liquor is increased through the warming up. The lower part of the crystallization grower is mainly to make the supersaturated solution through the central descending tube straight into the bottom of the grower, and then slowly through the fluidization of the crystal bed layer, so as to disappear the phenomenon of supersaturation, and the crystals will gradually grow. According to the size of the particle size automatically from the bottom to the top of the hierarchical arrangement, and the concentration of the crystal slurry is also from the bottom to the top of the gradual decline, rising to the circulating pump near the inlet has become clear liquid. Classification of the operation method so that the bottom of the grains and the upper part of the grain size has not grown to the product separated from each other, take out the tube is inserted in the bottom, so the product is taken out of the uniform spherical large-grained crystals, which is its biggest advantage. But the circulation pump delivery in the whole crystallizer is a certain amount, which causes the crystallizer grain fluidization of the terminal velocity and slurry concentration (that is, the size of the void rate) of the limitations, which will inevitably bring about two shortcomings: the first is a larger degree of supersaturation, but the safe supersaturation in the middle of the stabilization zone or a little bit on the side. So the elasticity of production capacity is very small. The second disadvantage is that due to the existence of the above phenomenon, resulting in the same diameter of the equipment than the crystal slurry cycle operation of the production capacity is several times lower.
Characteristics of system
- Lowest energy consumption and operation cost, electricity consumption of one ton water's evaporation is 2.2kw/℃.
- Temperature difference is small, heating is gentle, the loss of product is less.
- Compact structure and lower building cost; plant area is 50% less than that of traditional evaporator.
- Surrounding is friendly, no gas and no steam.
- Good adaptability in low loading condition, flexibility of operation is good and has a longer service life.
- Consumption of circular water is low and energy saving is obvious.
- No fresh steam is needed.
- Evaporation can be carried out under 40℃ and equipment need not to be frozen, specially suitable for thermal activity products.
