Applications

Production Process

First, the sulfur is crushed into powder, and sent into the combustion furnace with compressed air for combustion at 600 ~ 800℃. The amount of air added is about 2 times of the theoretical amount, and the concentration of gas SO2 is 10-13.
Second, after cooling, dust removal and filtration, the sublimated sulfur and other impurities are removed, and the gas temperature is reduced to about 0℃, and it is passed into the series reactor
The third stage reactor is slowly added with mother liquor and soda soda solution for neutralization reaction, the reaction formula is as follows:
2NaHSO4+ Na2CO3 — 2Na2SO4 + CO2+ H2O
The resulting sodium sulfite suspension is successively passed through the second stage and the first stage reactor for absorption reaction with SO2 to form the crystallization of sodium metabisulfite.
