Embodiment 1
[0075] (1) Configure desulfurization liquid and inject it into the desulfurization device
[0076] The desulfurization catalyst (production batch number 20200410) developed by Sichuan Binghui Environmental Protection Technology Co., Ltd. is selected. It is composed of a solid catalyst and a liquid auxiliary catalyst. First, the solid catalyst F is dropped into the first dissolving tank 19, and then the fresh water H is used to dissolve and then added to the regeneration chamber 52 with the pump 21; the liquid auxiliary catalyst G is dropped into the second dissolving tank 20, and then fresh water H is used to dissolve The water H is properly diluted and added to the regeneration chamber 52 with the pump 22 . Finally, add fresh water H to the entire desulfurization device until it is higher than the partition 6 of the regeneration tank.
