Sodium bicarbonate (baking soda) dry desulfurization special crusher
The dry desulphurization process is a complete set of grinding and powder spraying device with the combination of the grinder and the conveying fan with its own classification system. The fine powder of sodium bicarbonate after grinding is layered or porous structure, the particle size is uniform and has good dispersion, and then the solid ultrafine powder is sprayed directly into the furnace or the reaction tower through multiple nozzles. It can effectively remove more than 95% of SO2 and HCI in the exhaust gas, and the removal rate can even reach 99%.
Sodium bicarbonate (baking soda, NaHCO3) can be used as an adsorbent for flue gas desulfurization. It removes acid pollutants from flue gas by chemisorption, and at the same time, it can also remove some inorganic and organic trace substances by physical adsorption. In this process, sodium bicarbonate fine powder is directly injected into the high temperature flue gas of 140-250℃. At high temperatures, sodium bicarbonate decomposes to form sodium carbonate Na2CO3, H2O, and CO2.
The newly produced sodium carbonate Na2CO3 has a high degree of reactivity at the moment of formation, and can spontaneously react with acidic pollutants in the flue gas in the following ways:
2NaHCO3 → Na2CO3+H2O+CO2↑
Na2CO3+2SO2+H2O → CO2↑+2NaHSO3
Na2CO3+SO2+H2O → H2O+CO2↑+Na2SO3
- 01 Cost SavingsIt can not only meet the harsh requirements of environmental protection, but also effectively reduce investment and operating costs compared with other flue gas purification methods.
- 02 Dry Process Desulfurization TreatmentDry process desulfurization can effectively remove more than 95% of SO₂ and 99% of HCl in the tail gas.
- 03 Clean and Environmentally FriendlyThe crushing system is closed, less dust, low noise, and the production process is clean and environmentally friendly.
- 04 Easy OperationIntelligent control system, can be operated with one click, at any time to monitor sulfur dioxide concentration, system air volume, feeding volume, grinding temperature and other key parameters.
