Sds Desulfurization Ash Recovery Technology

SDS Desulfurization Ash Recovery Technology targets solid waste desulfurization ash generated from SDS flue gas desulfurization of various types. Based on pollution source analysis and following the principles of source reduction, resource recycling and advanced treatment, our company has developed a complete set of technologies for the synergistic purification and conversion of multi-component waste salts with full-process control. The core technologies include "enhanced high-efficiency purification pretreatment of desulfurization ash", "multi-path regeneration of desulfurizers" and "enhanced ammonium sulfate separation". We have also developed key equipment such as desulfurization ash reaction and separation units, desulfurizer reaction and regeneration systems, and ammonium sulfate separation units for complex systems. This sds desulfurization ash recovery technology solves the key challenges of difficult separation and purification control of complex multi-component waste salts, severe scaling, clogging and corrosion of equipment, and difficulty in ammonium sulfate crystallization. It achieves over 95% sodium resource recycling rate in SDS desulfurization ash, over 90% desulfurization ash recycling rate, with the regenerated desulfurizer sodium bicarbonate purity exceeding 98% and ammonium sulfate purity exceeding 98.5%.
