1. After melting, clarification and high-efficiency filtration, the sulfur is added to the sulfur incinerator by the sulfur pump.
2. After compression, drying and purification, the air is passed to the sulfur incinerator, and SO2 gas (furnace gas) is generated by sulfur incineration.
3. The furnace gas is cooled by the waste pot to recover steam, and then enters the sulfur removal reactor to remove the subliated sulfur in the gas to obtain pure SO2 content of 20.5%(volume) gas, which enters the absorption tower.
4, soda ash with a certain concentration of lye, and sulfur dioxide gas reaction to obtain sodium bisulfite solution.
5. Sodium hydrogen sulfite solution is neutralized by caustic soda to obtain sodium sulfite solution.
6. The sodium sulfite solution enters the concentrator and adopts a double-effect continuous concentration process. The water was distilled off to obtain a suspension containing sodium sulfite crystals.
7. Put the qualified materials of the concentrator into the centrifuge to realize solid-liquid separation. The solid (wet sodium sulfite) enters the air dryer and is dried by hot air to obtain the finished product.
8. The mother liquor is recycled to the alkali distribution tank for recycling.
