Recycling system and recycling method of waste zinc oxide desulfurizer

The invention discloses a recycling system and a recycling method of a waste zinc oxide desulfurizer, and belongs to the technical field of desulfurizers. A recycling system of a waste zinc oxide desulfurizer comprises a high-temperature oxidizing roasting device, an acid leaching device, a synthetic reaction device and a low-temperature calcining device, the system further comprises a flue gas dust removal device, a desulfurization device, a high-temperature flue gas exhaust line, a roasting material bypass line, a desulfurization material return line, a roasting flue gas return line, a dust removal flue gas return line and a dust removal flue gas waste heat utilization line. By means of the system, secondary pollution caused by sulfur emission in the waste desulfurizing agent regeneration process is reduced, zinc loss is reduced, waste desulfurizing agent substances are completely recycled, the regeneration rate is increased, and energy consumption is reduced. 一种废氧化锌脱硫剂的再生利用系统及再生利用方法，属于脱硫剂技术领域。一种废氧化锌脱硫剂的再生利
