Desulfurization is aimed at the characteristics of industrial furnace flue gas concentration of component temperature and so on, by acid and alkali neutralization method, to remove the acid gas in the flue gas at present there are wet by way of semi-dry desulfurization is stitch and dry wet desulfurization is one of the common technology, through the efficient atomization nozzle spray the lye to the reaction tower, the smoke and fog alkaline layer containing acidic gas contact one method to remove the acid components, according to the situation can be added in the reaction tower packing layer to improve the efficiency of reaction semi-dry and dry process was developed by our company on the basis of wet desulfurization method, adaptive targetedAnd the efficiency is more prominent and improved

Dry desulfurization and wet desulfurization.Wet desulfurization is the most studied and applied method in many countries.This method USES liquid absorbent such as water or alkali solution to wash flue gas desulfurization method, which can be divided into two categories. SO2 is removed by absorption.The equipment used in wet desulfurization is simple, easy to operate and has high desulfurization efficiency.However, the flue gas temperature after desulfurization is low, which is unfavorable for chimney smoke diffusion.It is used because different absorbent can obtain different by-products.
Basic principle:
Reduced desulfurizer + sO2= sulfites (absorption process)
Sulfites +O2= sulfate (oxidation process)
The alkaline desulfurizer absorbs SO2 and reacts to form sulfites, which are oxidized to a stable sulfate and then processed into the desired product.So any
Flue gas desulfurization is a chemical process.
