This invention discloses an integrated
crystallization device for absorption and mixing. The water-distributing
crystal vortex shell includes an outer shell, an inner shell concentrically located outside the inner shell, and a bottom cover plate and a top cover plate fixedly covering the upper and lower ends of the annular gap formed by the outer shell and the inner shell. The inner shell has several perforations spaced apart on its side wall. A water inlet
pipe supplies water to the closed annular interlayer space formed by the outer shell, the inner shell, the bottom cover plate, and the top cover plate. A
seed crystal conveying
pipe communicates with the inside of the inner shell and
spins and conveys seed crystals into the inner shell. A precipitant dosing
pipe extending into the inner shell at its lower end can deliver precipitant into the inner shell. A guide
barrel fixedly inserted into the lower end of the inner shell forms an annular
discharge port for
crystal downward flow between the outer side of the upper end and the inner side of the lower end of the inner shell. A
water flow driver fixed to the inner side of the lower end of the guide
barrel can provide downward flow power for the mixed liquid inside the inner shell of the water-distributing
crystal vortex shell. This invention does not require the introduction of an additional return water pump, thus solving the problem of
high energy consumption in fluidized reaction crystallizers.
