Welcome: Yiwu Weihao Machinery Equipment Company
DTB Crystallizer (Draft Tube Baffle Crystallizer)
As a leading manufacturer of industrial crystallization equipment, Yiwu Weihao Machinery Equipment Company specializes in designing and manufacturing high-efficiency DTB crystallizers (Draft Tube Baffle Crystallizers), a core equipment for continuous industrial crystallization. Our DTB crystallizers adopt the classic draft tube baffle structure, integrating crystallization, circulation, and crystal classification in one unit, ensuring uniform crystal particle size, high product purity, and stable continuous operation, widely used in chemical, salt production, metallurgy, and environmental protection industries.
The DTB crystallizer is characterized by its built-in draft tube and baffle, which divide the crystallizer into a crystallization zone and a clarification zone. The working process is as follows: 1. The feed liquid is continuously fed into the crystallizer, and the circulation pump drives the liquid to flow upward through the draft tube at a stable speed. 2. In the draft tube, the liquid is fully mixed with the crystal slurry, and the solute reaches supersaturation under the action of evaporation or cooling, forming new crystal nuclei and promoting the growth of existing crystals. 3. The baffle separates the crystal slurry: large-grain crystals settle to the bottom of the crystallizer for discharge, while small-grain crystals are circulated back to the draft tube to continue growing. 4. The clear mother liquor in the clarification zone is recycled or discharged, ensuring continuous and efficient crystallization operation.
Classic DTB Structure: Integrates draft tube and baffle, realizing crystallization, circulation, and crystal classification in one unit, compact layout and small footprint.
Uniform Crystal Particle Size: The unique circulation design ensures uniform mixing of feed liquid and crystal slurry, avoiding crystal agglomeration, and producing high-quality crystals with consistent particle size.
High Separation Efficiency: Stable circulation velocity prevents crystal deposition and scaling, ensuring continuous operation and high crystallization efficiency.
High Product Purity: Closed-loop operation and effective crystal classification reduce impurities in the final product, purity up to 99.5% or more, meeting industrial standards.
Strong Adaptability: Suitable for various solutes, including chemical salts, industrial salt, and high-salt wastewater crystallization; compatible with evaporative and cooling crystallization processes.
Stable & Reliable: Made of 304/316L stainless steel or duplex stainless steel, corrosion-resistant and wear-resistant; PLC automatic control system ensures stable operation and easy maintenance.
Customizable Design: According to customer’s feed liquid properties, crystal particle size requirements, and production capacity, customize the size and configuration of the DTB crystallizer; support modular integration with evaporation systems.
Our DTB crystallizers are widely used in various industrial fields that require continuous, high-efficiency crystallization, providing reliable solutions for enterprises, including but not limited to:
Chemical Industry: Crystallization of sodium chloride, sodium sulfate, ammonium chloride, potassium nitrate, and other chemical salts; purification of chemical intermediates and organic compounds.
