Embodiment 2

[0018] A circulating crystallizer, except that the mother liquor return tank pipeline communicates with the intermediate tank, the other structures are exactly the same as the first embodiment.

[0019] See attached figure 2 :

[0020] During work, the initial crystallization solution is placed in the head tank 9, cooled by the condenser 10 when flowing through the circulation pipeline, and then sent into the crystallization tank 1, under the action of the stirring rod 4 in the crystallization tank 1, there is constantly A small amount of crystallization and mother liquor flow into the intermediate tank 8 from the liquid outlet 6, and the lower layer of the intermediate tank 8 gathers crystals, but the overflow port 7 continuously has the mother liquor flowing out and passing into the circulation pipeline. After a certain time interval, the crystallization solution is fully mixed in the crystallization tank 1, and more and more crystals are deposited at the bottom of the cry...

Abstract

A circulating crystallizer, comprising a crystallization tank, a cooling interlayer arranged around the crystallization tank, a stirring bar is arranged in the crystallization tank, a liquid inlet and a liquid outlet are arranged on the crystallization tank, and the liquid outlet and the A circulation pipeline is arranged between the liquid inlets, and an intermediate pool with an overflow is arranged in sequence on the circulation pipeline, a high-level tank and a condenser for storing the initial solution of crystallization, and the circulation pipeline is also equipped with a circulation Mercury, the crystallization tank is also provided with a crystallization liquid outlet below the crystallization tank, and the crystallization liquid outlet is connected with the crystallization tank. vacuum pump. The circulating crystallizer mother liquid is circulated back to the crystallization tank, which has high efficiency and low energy consumption.

Description

(1) Technical field [0001] The invention relates to a circulating crystallizer. (2) Background technology [0002] In the existing crystallizer, the highly concentrated solution is placed in a crystallization tank with a liquid inlet and outlet, and a cooling interlayer is arranged around the crystallization tank. A coil for cooling medium circulation is arranged in the cooling interlayer, and a stirring rod is arranged in the crystallization tank. Stir the highly concentrated solution with a rod while cooling it. After the highly concentrated solution is cooled, the highly concentrated solution crystallizes at the bottom of the crystallization tank. Pour out the mother liquor above to take out the crystallization. In this way, it is inconvenient to take crystallization, slow heat transfer, serious scab, long crystallization time, low efficiency, high energy consumption, sharp cooling of high-concentration solution, large fluctuations in solution supersaturation, and initial...
