5等高价态易于被吸收的化合物。然后在后段的脱硫塔被吸收下来,达到脱除目的。但是,臭氧与烟气反应过程中,由于气流从进口管道进入反应器时,流道面积突然扩大,导致反应器截面上气流分布极不均匀,反应器中心部位和反应器边缘的气体流量不一致,使一部分烟气与臭氧发生充分反应,而另一部分烟气几乎不发生反应。因此,需要一种含有臭氧混合板的臭氧投加均布器,使得烟气与臭氧能够充分混合发生反应。
Ozone denitration technology utilizes the advanced oxidation of active groups. The main component of ozone is a strong oxidant, which can easily oxidize NO to high-valent compounds such as NO 2 , NO 3 , and N 2 O 5 that are easily absorbed. Then the desulfurization tower in the later stage is absorbed to achieve the purpose of removal. However, during the reaction between ozone and flue gas, due to the sudden expansion of the flow channel area when the airflow enters the reactor from the inlet pipe, the airflow distribution on the cross section of the reactor is extremely uneven, and the gas flow at the center of the reactor and the edge of the reactor are inconsistent. A part of the flue gas is fully reacted with the ozone, while the other part of the flue gas is hardly reacted. Therefore, there is a need for an ozone dosing uniformizer containing an ozone mixing plate, so that the flue gas and ozone can be sufficiently mixed to react.

The steel plates are vertically connected end to end. The distribution plate includes a mother pipe, a distribution pipe, and a dosing unit. The mother pipe is fixed on the shell. The distribution pipe is vertically and cross-connected to the mother pipe. The connection points are fixed and communicated by flanges. Although this ozone head dosing device uses a multi-point gas distribution method to make the ozone and the mixture along it uniform, but because the ozone is discharged from the air outlet of the dosing unit and then mixed with it, it needs to wait for a certain time before contacting The full contact of the flue gas leads to a longer oxidation process, so there is room for improvement.
