Performance characteristics of DTB draft tube baffle crystallizer

- Jan 03, 2019 -

The DTB draft tube baffle crystallizer exhibits a large internal flow velocity and a small external circulation flow rate in the application, which can reduce secondary nucleation due to external fluid flow, and is therefore mainly used for producing larger particle size. Crystal. The DTB draft tube baffle crystallizer has a diameter ranging from 0.5 m to 10 m and can produce crystals in the range of 0.5 to 1.5 mm.

In use, the DTB guide tube baffle crystallizer belongs to a typical crystallizer internal circulation type crystallizer. The crystal residence time is generally 3 to 4 hours, and the crystal density can be as high as 25% to meet the crystallization requirements of various materials. . Due to the special configuration of the special propeller, high-efficiency internal circulation is achieved, and the secondary crystal nucleus is hardly present, and the crusting of the inner wall is rarely observed.

Moreover, the quality of the products obtained by using the DTB guide tube baffle crystallizer is reliable, the supersaturation of the crystal slurry is uniform, the particle size distribution is good, and the production operation with high efficiency and low energy consumption is realized. Users can install panning legs as needed to achieve continuous production operations. The crystallizer can be cooled and crystallized, and can also be used for vacuum evaporation and cooling crystallization, and has strong applicability, reliable operation and less failure.
