Air Classifier Mill Pulverizer Working Principle
Use of Sodium Bicarbonate
Sodium bicarbonate (NaHCO3), used as an adsorbent for flue gas desulfurization, is sprayed into high-temperature flue gas directly, sodium bicarbonate decomposes at high temperature to form sodium carbonate Na2CO3, H2O and CO2. The newly produced sodium carbonate Na2CO3 has a high reactivity at the moment of formation, can efficiently react with acidic substances in the flue gas, remove more than 95% of SO2; the removal rate of HCl can reach 99%.
Principle of chemical reaction of sodium bicarbonate
NaHCO3 + HCl → NaCl + H2O + CO2
2NaHCO3 + SO2 + ½ O2 → Na2SO4 + H2O + 2 CO2
NaHCO3 + HF → NaF + H2O + CO2
Characteristics of Sodium Bicarbonate Flue Gas Treatment
The process is simple and reliable;
The auxiliary (sodium bicarbonate) and the residue are non-irritating and non-toxic;
The residue is dry solid with a small amount;
Could adjust sodium bicarbonate input with the concentration of harmful substances;
Auxiliary costs are higher, but processing costs are low.
In the fields of ultrafine grinding and classification in the pharmaceutical, food, chemical, mineral, new materials, solid waste treatment and other industries, ALPA has mature and fully customized solutions and helps you design the ideal system to meet your needs.
