Description

Ozone uniform distribution device

Technical field

The present application relates to the technical field of environmental treatment, for example, to an ozone uniform distribution device.

Background technique

The prevention and control of air pollution is not only a major livelihood issue, but also an important starting point for economic upgrading. The focus of prevention and control work is to reduce pollutant emissions in order to accelerate the transformation of desulfurization, denitration and dust removal in key industries, strictly control new capacity in high energy consumption and high pollution industries, complete the elimination of backward production capacity in steel and other industries, and vigorously promote clean production. The NO _x (Nitrogen Oxides) in the sintering process of iron and steel plants is mainly derived from the combustion of fuel during the sintering process, and the concentration of NO _x is usually about 300 mg / Nm ³ . The nitrogen oxides produced during the combustion process are mainly NO (Nitric Oxide) and NO ₂ (Nitrogen Dioxide, Nitrogen Dioxide). Experiments show that the main component of nitrogen oxides in exhaust gas is NO. In general, NO _x accounts for more than 95% and NO _{2 is} less than 5%.

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 applicant previously applied for a patent with a publication number of CN201711182415.5, which discloses an ozone dosing and spreading device, which adopts a multi-point balanced gas distribution method, which includes a shell and a distribution plate. 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.
