摘　　要：对白云石碳化法生产水合碱式碳酸镁、工业氧化镁、超细含镁碳酸钙（简称两镁一钙）工业装置中，白云灰乳同含ＣＯ２窑气进行碳酸化反应时的鼓泡塔进行了数学模拟。白云灰乳先经喷雾碳化塔，Ｃａ（ＯＨ）２基本反应完全，再经鼓泡碳化塔，Ｍｇ（ＯＨ）２继续进行反应，采用Ｍｇ（ＯＨ）２同ＣＯ２反应为拟一级反应，建立了数学模型，并进行了数学模拟计算，得出了较为实用的、能满足工业生产需要的计算模型和数据。The mathematical simulation of the bubbling column in dolomite carbonation process is introduced.The carbonation of Ca(OH) 2 in dolomite mortar is nearly finished in the spraying column,and the carbonation of Mg(OH) 2 is carried out in the bubbling column.The reaction of Mg(OH) 2 and CO 2 is taken as quasi-first order reaction,thus,the mathematical model of the bubbling column is obtained.The results show that it is satisfied with industrial production.
