Working Principle
- The Air Classifier Mill, Feeding system and draft Fan form a complete system. The grinding zone is formed by high-speed rotating grinding disc and gear ring, the material is grinded by the superposition of friction, shearing, collision and other grinding forces in the grinding zone, the grinded material moves to classifying area with rising airflow under the action of the fan pulling force.
- In the classifying area, under the strong centrifugal force generated by the high-speed rotating classifying impeller, the coarse and fine materials are separated, the fine particle which meeting the particle size requirements could across classifier impeller and then enter flue gas pipeline, the coarse particle fall to grinding zone to continue grinding.
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.
