Ammonia calcium desulfurization regeneration cycle ammonia byproduct active calcium system

A system for regenerating circulating ammonia byproduct active calcium through ammonia-calcium desulfurization adopts a two-stage desulfurization tower and a scrubber tower as a main line of the system to form a unit for preparing relatively pure ammonium sulfate by an aeration oxidizer and a coal ash filter, a unit for preparing relatively pure lime milk by an ash reactor and an ash milk refiner, and a unit for regenerating relatively pure ammonia water by a calcium removal reactor and a calcium carbonate filter. A complete closed-loop ammonia balance regeneration desulfurization and by-product active calcium system is formed by using a preparation tank and a carbonization tank to prepare an active calcium unit and the like, so that flue gas ultra-clean emission can be realized while efficient desulfurization is implemented, waste is turned into wealth while near-zero emission of waste water and waste residues is realized, and relatively high economic benefits are obtained. 一种氨钙脱硫再生循环氨副产活性钙的系统，以两级脱硫塔加洗气塔为系统主
