摘要 介绍软锰矿、菱锰矿吸收SO2烟气制取硫酸锰的新方法和新技术,在热电分厂锅炉排放烟气综合治理中的应用研究。通过吸收塔的循环吸收、压力过滤、净化、热结晶、离心分离和干燥等工艺过程,该技术不仅可使除尘效率≥90%,SO2吸收率≥92%,实现SO2和烟尘的达标排放,而且还可获得质量达到工业二级品的脱硫副产品硫酸锰。 The new technology is characterized by SO2 in flue gas being absorbed by the slurry of pyrolusite and manganese spar in a circulating absorbing tower with MnSO4 as a by-product.This paper provided the process flow chart,design parameters and major equipment,and analyzed cost/effectiveness of the technology.
