Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to a flue gas desulfurization tower for petroleum processing. Background Art

[0002] The main chemical elements of petroleum are carbon, hydrogen, sulfur, nitrogen and oxygen. Among them, sulfur and nitrogen are non-hydrocarbon components. During the petroleum processing, they will form sulfur and nitrogen oxides and be discharged into the atmosphere with the flue gas from the chimney, causing environmental pollution. In order to protect the environment in today's society, the exhaust gas from the chimney needs to be purified by the flue gas desulfurization device.

[0003] Prior art CN206965484U A flue gas desulfurization device and a flue gas desulfurization dust removal system. The utility model relates to a flue gas desulfurization device and a flue gas desulfurization dust removal system. The flue gas desulfurization device comprises a desulfurization tower. A primary desulfurization spray device and a secondary desulfurization packing structure are sequentially arranged from bottom to top between the flue gas inlet and the flue gas outlet in the desulfurization tower. The primary desulfurization spray device is used to spray a desulfurization agent for wet desulfurization into the desulfurization tower for primary desulfurization; the secondary desulfurization packing structure comprises a desulfurization packing layer and a secondary desulfurization injection device, wherein the secondary desulfurization injection device is used for continuously injecting a sodium-based or potassium-based desulfurizer onto the desulfurization filler layer to form a desulfurizer liquid film on the filler surface for secondary desulfurization. The flue gas desulfurization device has a compact structure; the desulfurization filler layer serves as a special reaction area for secondary desulfurization, the contact time between the desulfurizer and the flue gas is long, the contact area is large, the utilization rate of the desulfurizer is high, and the overall efficiency of deep removal of sulfur oxides is high; and the secondary desulfurization does not require a special desulfurizer circulation recovery system, so the initial investment is small and the operating cost is low.

[0004] A flue gas desulfurization device and a flue gas desulfurization and dust removal system in the prior art first react with a primary desulfurization spray device, and then the flue gas enters the desulfurization packing layer, and is discharged from the flue gas outlet after continuous reaction with a secondary desulfurization injection device. During this process, the desulfurization packing layer needs to be cleaned and maintained regularly, but the existing flue gas desulfurization device and the packing layer are an integrated structure. Such a design increases the difficulty of maintaining the packing layer in the later stage. Utility Model Content
