Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to a horizontal flue gas desulfurization treatment device. Background Art

[0002] Flue gas desulfurization refers to the process of removing sulfur dioxide (SO2) from flue gas through a series of processes and equipment. Sulfur dioxide is one of the main pollutants produced by burning fuels (such as coal, oil, etc.), which is harmful to the environment and human health. Therefore, flue gas desulfurization is one of the very important environmental protection measures in the industrial and energy industries. The main methods of flue gas desulfurization include wet desulfurization and dry desulfurization. Wet desulfurization is to bring flue gas into contact with a desulfurizer (such as limestone slurry, ammonia water, etc.) so that sulfur dioxide is absorbed into the desulfurizer to form sulfates and other substances, ultimately achieving the purpose of reducing sulfur dioxide emissions.

[0003] Chinese patent CN218422010U discloses a flue gas desulfurization treatment device, in which a delivery pipe is bolted to one side of the outer wall of the machine body, a fixing frame is screwed to the inner wall of the machine body, an exhaust pipe is welded to the inner wall of the fixing frame, the exhaust pipe and the delivery pipe are connected to each other through pipes, and a refinement head is threadedly connected to the outer wall of the bottom end of the exhaust pipe. When the flue gas passes through the delivery pipe, the waste heat of the flue gas is first recovered through a perforated pipe. After the waste heat is recovered, the flue gas is refined in the machine body through the refinement head, and the refined flue gas is desulfurized by a solution. The treated flue gas is secondary desulfurized by an atomizing nozzle and finally discharged after a fan. During the discharge process, it is finally filtered through a filter bucket, which solves the problem of incomplete flue gas purification when the flue gas is not refined and fully contacts the solution.

[0004] The above patent improves the shortcomings of the flue gas desulfurization treatment device in the prior art, which has no flue gas refinement structure and cannot make the flue gas fully contact with the solution. When the flue gas is not refined and fully contacted with the solution, it will cause incomplete flue gas purification. This embodiment provides another implementation plan for the problems raised in the above patent. Utility Model Content
