[0002] The current process for producing acid from yellow phosphorus involves spontaneous combustion of phosphorus sludge in a furnace to produce phosphorus pentoxide, which is then absorbed with water to produce phosphoric acid. The temperature difference between the lean and rich phosphorus sludge production processes is significant. Traditional graphite spray tower nozzles are made of spiral plastic, and the high-temperature phosphorus pentoxide vapor easily melts the nozzles. This results in poor absorption efficiency and high exhaust temperatures, severely impacting subsequent absorption processes. The subsequent plastic PP tower is not heat-resistant, creating limitations and hindering production increases. Summary of the Invention
