【摘要】：总结了矿浆在烟气脱硫及资源化的应用,全面综述了磷矿浆、锰矿浆、镁矿浆、赤泥浆、锌矿浆、铜矿浆、镍矿浆7种不同类型矿浆烟气脱硫及资源化,从矿渣的数量、赋存形态、烟气脱硫机理、影响因素、工艺路线、操作参数、应用案例等进行论述,并对比分析各自优点和缺点。总结出矿渣或贫矿与水配制矿浆作为新型脱硫剂可以高效脱除烟气中低浓度二氧化硫,同时综合利用矿渣中金属资源,达到"以废治废"目的。指出虽然矿浆烟气脱硫技术可行、运行成本低、副产物量大,可为烟气脱硫及资源化工业应用提供新思路,但是依然存在污染物同时治理研究较少、脱硫产物高效分离成本较高等问题,今后应加强多污染同时脱除、脱硫副产物分离及资源化利用途径的研究。
[Abstract]:The application of pulp in flue gas desulphurization and resource utilization is summarized. The desulphurization and resource utilization of seven different types of pulp, such as phosphate slurry, manganese slurry, magnesium slurry, red mud, zinc slurry, copper pulp and nickel pulp, are summarized. Occurrence form, flue gas desulphurization mechanism, influencing factors, technological route, operation parameters, application cases and so on are discussed, and their respective advantages and disadvantages are compared and analyzed. It is concluded that slag or slurry prepared with lean ore and water as a new desulfurization agent can effectively remove sulfur dioxide in flue gas with low concentration of sulfur dioxide and make comprehensive use of metal resources in slag to achieve the purpose of "treating waste by waste". It is pointed out that although the technology of flue gas desulfurization with slurry is feasible, the operation cost is low, and the amount of by-products is large, it can provide a new idea for the industrial application of flue gas desulfurization and resource utilization, but there is still less research on simultaneous treatment of pollutants. The high efficiency separation cost of desulphurization products is very high. In the future, we should strengthen the research of multi-pollution simultaneous removal, desulphurization by-product separation and utilization of resources.
