Draft Tube Baffle Crystallizer

Draft Tube Baffle Crystallizer(DTB) crystallizer is a highly effective crystallizer. DTB crystallizer is in the form of an internal guide streaming cylinder. Under the action of stirring and mandatory circulating pumps, the way to control the overall stream of the crystallizer. Achieve crystalline effect. DTB is widely adopted in industries such as the chemical industry, food, pharmaceuticals, etc. After years of operation practice, this type of crystallizer has good performance and can produce uniform and larger grains (granularity can reach 600 to 1200 µm). The production intensity is Higher, so it is not easy to crystallize scars in the device. It has become one of the main forms of continuous crystallizers, which can be used for the crystalline operation of the vacuum cooling method, an evaporation method, direct contact with the freezing method, and a reaction method. The D.T.B. type crystallizer is a widely used continuous crystallizer. It is a slurry circulating mixing suspension type and is usually suitable for vacuum or evaporation crystallization. The equipment is of vacuum type, with a baffle inside, and a crystal settling and grading area is formed between the baffle and the outer wall. Inside the baffle is a guide tube. Blender included. The feed is fed from the bottom, mixed with the circulating suspension, and then ascends through the guide tube. The denominator liquid is discharged from the crystal sedimentation zone, and there is an upward liquid flow in the sedimentation zone. The fine crystals overflow together with the mother liquor, while the large crystals settle down and merge with the circulating liquid in the guide tube. Therefore, a large slurry density can be maintained and the generation of crystals can be controlled.
