【摘要】：探究了氫氧化鎂乳液的制備工藝,并采用鼓泡式反應(yīng)裝置對(duì)氫氧化鎂脫硫反應(yīng)特性進(jìn)行了研究。結(jié)果表明,氫氧化鎂的粒徑中值隨反應(yīng)物濃度的增大而增大,粒徑中值460~490 nm、濃度0.7 g/L的氫氧化鎂脫硫效果較佳;氫氧化鎂脫硫效率隨著其濃度的增大、鼓泡深度的提高而顯著增大,隨著SO_2濃度及煙氣流量的增高,脫硫效率降低,而且在SO_2濃度為2 500 mg/m~3、吸收液溫度低于50℃時(shí),脫硫效率達(dá)到95%以上;SO_2在氫氧化鎂顆粒表面的接觸、反應(yīng)過程分為快速區(qū)、過渡區(qū)和穩(wěn)定區(qū)三個(gè)階段。
[Abstract]:The preparation process of magnesium hydroxide emulsion was studied, and the reaction characteristics of magnesium hydroxide desulfurization were studied by bubbling reaction device. The results show that the median particle size of magnesium hydroxide increases with the increase of reactant concentration, and the desulfurization efficiency of magnesium hydroxide increases with the increase of the concentration of magnesium hydroxide at the concentration of 0.7 g / L, and the median particle size increases with the increase of reactant concentration. With the increase of SO_2 concentration and flue gas flow rate, the desulfurization efficiency decreased, and when the SO_2 concentration was 2 500 mg / m ~ (3), the temperature of the absorbent solution was lower than 50 鈩，
