Problems solved by technology
[0007] In order to solve the above technical problems, the present invention provides an integrated device for improving flue gas forced oxidation, desulfurization and denitrification to solve the problem that the existing device has a low contact efficiency between liquid and flue gas during the desulfurization and denitrification process, and cannot pass through Structural improvement enables the sprayed liquid to fully contact with the flue gas; moreover, when the existing device replaces the spray liquid, it cannot realize height-adjustable liquid discharge according to the thickness of the residue in the barrel, resulting in waste of liquid phenomenon; lastly, the existing device cannot realize the separation of gas during desulfurization and denitrification, and has realized gas dispersion, and then realized the problem of sufficient contact with the spray liquid

The invention provides an integrated device for improving forced oxidation desulfurization and denitrification of flue gas, relates to the technical field of oxidation devices, and solves the problemthat sprayed liquid cannot be in full contact with the flue gas through structural improvement. The height-adjustable liquid discharge cannot be realized according to the thickness of residues in thebarrel body, so that the liquid waste phenomenon is caused; the separation of gas cannot be realized, the gas dispersion is realized, and the sufficient contact with the spraying liquid is further realized. The invention discloses an integrated device for improving forced oxidation desulfurization and denitrification of flue gas. The integrated device comprises a box body, and a blocking structureis arranged in the box body. Through the arrangement of the first extension structure, the protrusions A are welded to the top end face of the rectangular plate A in a rectangular array shape, and the protrusions A and the through holes B are arranged in a staggered mode; the protrusions A are of a triangular prism structure and are aligned with the spraying holes in position, so that liquid sprayed out of the spraying holes is sputtered after making contact with the protrusions A, and then the contact efficiency of gas and purified liquid is improved.
Description
technical field [0001] The invention belongs to the technical field of oxidation devices, and more specifically relates to an integrated device for improving forced oxidation, desulfurization and denitrification of flue gas. Background technique [0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied to the chemical industry where nitrogen oxides and sulfur oxides are generated. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. The benefits of ambient air purification are numerous. [0003] For example, the application number: CN201910882141.3, the present invention discloses an oxidation device for industrial denitrification and desulfurization environmental protection flue gas treatment, specifically relates to the field of oxidation devices, including a treatment box, the inner top of the treatment box is fixedly installed with a first inner box, The inside of the processing box i...
