The invention relates to a flue gas treatment system in a coking production process, and relates to the technical field of coking flue gas treatment. An atomization device is arranged in a desulfurization and denitrification system, a desulfurization agent is atomized through the atomization device so as to desulfurize the flue gas, and the denitrification agent is added into the denitrification device, so that the desulfurized flue gas is denitrified; the desulfurized flue gas and the denitrated flue gas are detected through a sulfur dioxide detector and a nitrogen detector in the desulfurization and denitration process, and the atomization amount of an atomization mechanism in the desulfurization device is adjusted when the flue gas is judged to be unqualified according to a comparison result with a preset value, so that desulfurization is accelerated; and when the desulfurized flue gas is controlled to be denitrified, the rotating speed of a third fan for conveying the desulfurized flue gas is adjusted according to a judgment result, so that the control precision of the desulfurization and denitrification process of the whole desulfurization and denitrification device is improved, and the flue gas treatment efficiency is further improved.
Description
technical field [0001] The invention relates to the technical field of coking flue gas treatment, in particular to a flue gas treatment system in a coking production process. Background technique [0002] Flue gas treatment in the coking process is the most important link in steel production. The current desulfurization process can be divided into pre-combustion, combustion and post-combustion desulfurization. It can reduce the corrosion of pipelines and equipment during gas transportation, improve production safety, and produce better economic benefits. However, the current coking process flue gas treatment systems on the market still have the following problems: [0003] In the existing coking process flue gas treatment system, during the reaction process of spraying liquid and gas, due to the intense molecular activity of gas, the contact between gas and liquid is not sufficient, and the reaction is not complete; [0004] The conventional flue gas treatment system in the...
