Description

Technical Field

[0001] This utility model relates to the field of yellow phosphorus production technology, and in particular to a device for purifying and recycling yellow phosphorus production wastewater. Background Technology

[0002] China is a major producer of yellow phosphorus, but the yellow phosphorus industry remains a high-energy-consuming and highly polluting sector. The electric furnace method for producing yellow phosphorus involves feeding a mixed charge into an electric furnace through a feed pipe. Under electrothermal heating, a reduction reaction occurs. The phosphorus-containing furnace gas is first subjected to multi-stage condensation and washing to obtain crude phosphorus, and then further refined and separated through multi-stage processes to obtain the finished phosphorus. This production process generates large amounts of wastewater and phosphorus sludge, causing severe environmental pollution and high treatment costs. This production route is complex, the phosphorus-containing furnace gas has a complex composition and high particulate matter concentration, and its performance is greatly affected by raw materials and operational factors. The comprehensive utilization level of raw materials is low, resulting in a low yellow phosphorus recovery rate.

[0003] The production of yellow phosphorus requires the treatment of wastewater generated during production. However, most wastewater treatment devices are currently designed as a single unit, making it difficult to clean the inside after wastewater treatment, which increases the difficulty of cleaning the device.
