System and method for continuously operating crude phosphorus purification in yellow phosphorus production process

The invention relates to a system and a method for continuously operating crude phosphorus purification in the yellow phosphorus production process, and belongs to the field of chemical engineering devices. The method adopts a continuous sedimentation technology, so enough standing time of crude phosphorus is ensured in the continuous overflow process from a refining tank A to a refining tank C during sedimentation of the crude phosphorus in order to achieve the sedimentation effect, so continuous operation can be achieved in the process production process; and compared with existing batch operation methods, the method of the invention has the advantages of high automation degree, high device utilization rate, and reduction of the device operation frequency. 本发明涉及一种黄磷生产过程中粗磷净化连续操作系统及方法，属于化工装置领域。该方法采用连续沉降的工艺，在粗磷沉降过程中，从精制槽A至C槽连续溢流过程中，保证粗磷有足够的停留时间，达到沉降效果，工艺生产过程中可实现连续操作；与现有间隙操作工艺相比自动化程度、设备利用率更高，减少设备操作频率。
