To produce baking soda suitable for removing more than 95% of SO2 and 99% of HCl from exhaust gas
The Sodium Bicarbonate Air Classifying Mill is capable of removing sulphur dioxide (SO2), hydrogen chloride (HCl) and other pollutants from municipal, hazardous, and sludge incineration processes, as well as cement plants, glass factories, steel mills and coke ovens.
Sodium bicarbonate (baking soda) raw material is uniformly fed into the chamber through a quantitative feeder at the lower part of the silo, which grinds raw material into a particle size of D90:20μm, allowing to adjust particle size according to specific requirements. The high-pressure fan then conveys the powders into the pipeline and sprays it directly into the flue gas, quickly reacting with acid gases and decomposing them into sodium carbonate (Na2CO3), H2O, and CO2 at high temperatures. Newly generated sodium carbonate has an incredibly high reaction activity that efficiently reacts with acidic substances in the flue gas.
NaHCO3 HCl → NaCl H2O CO2
2NaHCO3 SO2 ½ O2 → Na2SO4 H2O 2CO2
NaHCO3 HF → NaF H2O CO2
- Dry process desulfurization Desulfurization by dry process can remove more than 95% of SO2 and 99% of HCl in the tail gas.
- Easy to disassemble and wash Compact structure, easy to disassemble and wash. Cleaning In Place (CIP) optional, reducing downtime by removing stucked material.
