    摘要: An apparatus for crystallization, which contains a crystallization vessel, a seed supplying device, a feed solution supplying device and a tube baffle disposed within the crystallization vessel. The tube baffle is provided with a crystallization portion in an inner area and a lower area thereof, and the tube baffle and the crystallization vessel define a classification portion there between. The apparatus further contains an agitating fan for agitating the seed crystals and the feed solution, and a plurality of plate baffles disposed within the classification portion which define a buffer portion and a gravitational settling portion. The apparatus further contains a device for generating a rising velocity of a slurry containing fine crystals in the gravitational settling portion by discharging the slurry so that the rising velocity of the slurry is greater than a settling velocity of the fine crystals and an outlet for discharging the crystallized material.
