DTB crystallizerIs a high efficiency crystallization equipment, PLC control material temperature, its unique structure and working principle determines that it has high heat transfer efficiency, simple configuration, high production intensity, equipment is not easy to scar, convenient operation control, good operating environment and other characteristics, widely used in chemical, pharmaceutical, pesticide, and other industries of crystallization operations.
Working principle:DTB type crystallizer belongs to the typical crystal slurry circulation crystallizer. It has a diversion tube in the middle, and a cylindrical baffle around the diversion tube. There is a propeller (also can be seen as an internal circulation axial flow pump) in the lower short part of the diversion cylinder, which rotates at a lower speed. Driven by the propeller, the suspension rises to the surface of the liquid in the cylinder, then turns downward, flows to the bottom of the device along the annular channel between the guide cylinder and the baffle, and is sucked into the lower end of the guide cylinder again, thus circulating endlessly, forming a close to good mixing condition. A cylindrical baffle separates the crystallizer into a crystal growth zone and a fining zone. The annular gap between the baffle and the vessel wall is a clarification zone in which the effect of agitation is virtually eliminated, allowing the crystals to sedimented from the mother liquor, and only excess crystallites can follow the mother liquor out of the top discharge vessel of the clarification zone, thereby achieving control of the amount of crystallites.
