The invention discloses a byproduct recycling system applied to an SDA desulfurization process, and is used for solving the problem that SDA desulfurization byproducts cannot be recycled in the existing spray drying flue gas desulfurization technology. The system comprises a desulfurizing tower, a crusher, a grinder, a mixing device, a screw feeder, a surge bin, a pneumatic conveying device, a circulating ash bin, a circulating pulping tank, a conveying pump, a top tank and a rotary atomizer. Byproducts conveyed by the pneumatic conveying device enter the circulating ash bin through the control valve or are recycled by comprehensively utilizing the ash bin; the circulating ash bin is connected with the circulating pulping tank; the circulating pulping tank is connected with the top tank through the conveying pump; the top tank is connected with the rotary atomizer through a pipeline, the byproducts reaching the circulating ash bin return to the circulating pulping system of the original desulfurization system, after pulping is completed in the circulating pulping tank, the slurry is conveyed to the top tank through the conveying pump, the slurry is conveyed into the rotary atomizerthrough the top tank, and the slurry is atomized to be used for desulfurization reaction of the desulfurizing tower.
Description
technical field [0001] The invention relates to the technical field of by-product recycling of SDA desulfurization process, in particular to a by-product recycling system applied to SDA desulfurization process. Background technique [0002] Spray drying flue gas desulfurization technology (SDA) is a spray drying absorption process, which belongs to the semi-dry desulfurization process. Since the advent of the rotary spray desulfurization process, this technology has been widely accepted and applied by various countries in the world for its outstanding technical advantages and good performance characteristics. The SDA desulfurization process has the advantages of high desulfurization efficiency, simple system operation, low operating cost, no waste water generation, no equipment corrosion, etc., and is widely used in various fields. When the SDA desulfurization system is working, a large amount of by-products will be produced, and some of the by-products will accumulate at t...
