Lime: lime quality requirements. The so-called active ultra-fine lime powder, lime and water refers to the ability to respond. It refers to the degree of activity: a certain amount, a certain size range Henan ultrafine lime lime powder, mixed with water having a temperature and an amount of ultra-fine lime powder after Tianjin, lime and water to dissolve the reaction speed. The main reaction limestone wet desulphurization processes: wet limestone desulfurization process is typical of gas chemical absorption process, the occurrence of complex chemical reactions in flue gas cleaning process. Removal of SO2 from flue gas process is carried out in the gas, liquid and solid, the occurrence of gas - liquid reaction and liquid - solid reaction.
