Desulfurization system for co-producing active calcium by combining ammonia and calcium with regenerated ammonia water

The utility model relates to a desulfurization system for co-producing active calcium by combining ammonia and calcium with regenerated ammonia water, belonging to the technical field of atmospheric control. The ammonia-process primary incomplete desulfurization tower and the calcium hydroxide dry-process secondary complete desulfurization tower are used for replacing a primary desulfurization tower, a secondary desulfurization tower and a scrubbing recovery tower in the prior art, so that ammonia escape is effectively controlled, and ammonia regeneration and flue gas resource utilization are realized among desulfurization products; aerosol and moisture in the flue gas are adsorbed through dry desulfurization, clean emission of dry flue gas is achieved, and a material balance closed-loop circulation system which does not generate solid waste and waste water is formed. 一种氨钙联合再生氨水联产活性钙的脱硫系统，属于大气治理技术领域。本实用新型以氨法一级不完全脱硫塔和氢氧化钙干法二级完全脱硫塔取代了现有技术一级脱硫塔、二级脱硫塔及洗气回收塔，不仅有效地控制了氨逃逸，还在脱硫产物间实现氨再生及烟气资源化利用同时，通过干法脱硫吸附了烟气中的气溶胶及水分，实
