Struvite fluidization and crystallization device

The invention discloses a struvite fluidization and crystallization device. The device consists of four parts, i.e., a reaction system, a water feeding and chemical dosing system, a product collection system and an automatic control system, wherein a fluidization and crystallization pipe of the reaction system is a single cylindrical straight pipe without stepped pipe diameter change; grouped porous water feeding components are adopted by the water feeding and chemical dosing system, so that burst nucleation caused by local supersaturation can be effectively reduced, the total phosphorus removal rate of the device and the particle sizes of granular products are improved, and an external precipitation device is not needed. The device has the characteristics of being simple in structure, easy in processing, small in occupied area, high in total phosphorus removal rate, uniform in crystal grain sizes, convenient to adjust and control and convenient to manage; furthermore, an obtained crystal product is high in q
