Fixed source flue gas refers to harmful gases emitted by fixed pollution sources. In order to avoid air pollution caused by fixed source flue gas, it is necessary to treat the flue gas through an integrated desulfurization and denitrification device.

[0003] For example, the invention patent: "Integrated dust removal, denitrification and desulfurization device", with the announcement number "CN104606994B", allows the gas to contact with the desulfurization liquid sprayed from the desulfurization liquid spray device, and the sulfur dioxide in the gas reacts chemically with the desulfurization liquid. The reaction product flows into the lower desulfurization liquid storage tank with the desulfurization liquid, which can effectively purify the waste gas rich in dust, nitrogen oxides and sulfur dioxide. However, in the implementation of this patent, the flue gas is only contacted with the desulfurization liquid by spraying, which makes it difficult for the flue gas to fully contact and react with the desulfurization liquid, and it is not easy to fully purify the sulfur dioxide in the flue gas, and the purification effect is poor. Therefore, the present invention provides a fixed source flue gas desulfurization and denitrification integrated device for solving the above problems. Utility Model Content
