Background
Flue Gas Desulfurization (FGD) is an efficient desulfurization method for large-scale application in the industrial industry. The desulfurization technology can be classified into a dry method, a semi-dry method and a wet method according to the forms of the sulfide absorbent and the by-products. The dry desulfurizing process mainly utilizes solid absorbent to remove SO2 in flue gas, limestone fine powder is generally sprayed into a hearth to be heated and decomposed into CaO, SO2 in the flue gas is absorbed to generate CaSO3, and the CaSO3 and fly ash are collected in a dust remover or discharged through a chimney. The wet flue gas desulfurization adopts the gas-liquid reaction of a liquid absorbent under the ionic condition to further remove SO2 in the flue gas, and the system has the advantages of simple equipment, stable and reliable operation and high desulfurization efficiency. The dry desulfurization method has the advantages that no waste water and waste acid are discharged during treatment, and secondary pollution is reduced; the disadvantages are low desulfurization efficiency and large equipment.
