Problems solved by technology

However, practice has shown that due to the incomplete oxidation of nitric oxide and the low absorption rate of nitrogen oxides in the existing technology, the tail gas emission of nitrogen oxide waste gas treatment is still difficult to meet the standard. Therefore, the wet treatment of nitrogen oxides Process improvement still requires further efforts by researchers to explore

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figures 1 to 2 As shown, the structure of the exhaust gas treatment system containing nitrogen oxides in this embodiment is mainly composed of a first-stage scrubber 1, a second-stage scrubber 2, a third-stage scrubber 3, and a fan 4 connected in series. The air inlet at the bottom of the first-stage scrubber 1 enters, and the fan 4 is connected with the exhaust port of the third-stage scrubber 3, forming a certain negative pressure in each stage of the scrubber, and at the inlet of the first-stage scrubber 1, the exhaust gas at 5×10 5 It enters the treatment system under Pa pressure, and the treated waste gas tail gas is discharged into the atmosphere through the vent pipe 5 connected with the fan 4 after being tested to meet the discharge standard.

[0025]In this embodiment, the internal structures of the washing towers at...

Abstract

The invention relates to a nitrogen oxide waste gas treatment method and a treatment system thereof. The method includes: introducing nitrogen oxide containing waste gas into a first stage washing tower to conduct oxidation treatment to oxidize nitric oxide into nitrogen dioxide, introducing waste gas mainly containing nitrogen dioxide into a second stage washing tower to conduct reduction treatment to convert nitrogen dioxide into nitrogen, finally introducing the treated waste gas into a third stage washing tower, spraying a sodium hydroxide test solution to absorb the residual nitrogen dioxide gas in the waste gas, performing defogging treatment and then conducting emptying. The method and the system provided by the invention employs three-stage washing towers to treat nitrogen oxide waste gas, effectively improve the treatment efficiency of waste gas, and reduce the treatment cost.

Description

technical field [0001] The invention relates to a nitrogen oxide waste gas treatment method and a treatment system for realizing the method. Background technique [0002] Nitrogen oxides mainly include nitric oxide (NO) and nitrogen dioxide (NO 2 ), was recognized as one of the main pollutants of the atmosphere in the 1960s. The treatment of nitrogen oxides refers to the control, recovery or utilization of nitrogen oxides (NOx) in the exhaust gas by improving the combustion process and equipment or using catalytic reduction, absorption, adsorption and other exhaust gas denitrification methods. 2 ), or the purpose of harmless treatment of nitrogen oxides. The treatment methods mainly include flue gas denitrification and controlling the production of nitrogen oxides. [0003] At present, the flue gas denitrification methods mainly include dry method and wet method. Dry treatment technologies include catalytic reduction, adsorption and so on. The catalytic reduction method...
