DTB crystallizer

< . Crystallizer: < . B< . The crystallizer is a high-efficiency crystallization equipment. The material temperature is controlled by < . < . Its unique structure and working principle determine that it has high heat transfer efficiency. , simple configuration, convenient operation and control, and good operating environment. It is widely used in crystallization operations in chemical, pharmaceutical, pesticide, and other industries. : ' '. Working principle: There is a guide tube in the middle and a cylindrical baffle around the guide tube. There is a propeller (which can also be regarded as an internal circulation axial flow pump) near the lower part of the guide tube, rotating at a lower speed. Driven by the propeller, the suspension rises to the surface of the liquid in the tube, then turns downward, flows along the annular channel between the guide tube and the baffle to the bottom of the device, and is sucked into the lower end of the guide tube again, and the cycle continues. , forming close to good mixing conditions. The cylindrical baffle divides the crystallizer into a crystal growth area and a clarification area. The annular gap between the baffle and the wall is the clarification zone, where the influence of stirring has actually disappeared, allowing the crystals to settle and separate from the mother liquor. Only excess microcrystals can be discharged out of the vessel with the mother liquor at the top of the clarification zone, thus achieving Control of the amount of microcrystals.
