Nitrogen oxide oxidation apparatus used for environment quality analysis

Abstract

The invention discloses a nitrogen oxide oxidation apparatus used for environment quality analysis. The nitrogen oxide oxidation apparatus comprises an apparatus body; the apparatus body is mainly composed of an air inlet, an air outlet, an air inlet pipe and a filling layer, the air inlet pipe is arranged in the apparatus body, the air inlet pipe is communicated with the air inlet, and the air inlet pipe is extended to the bottom in the apparatus body, a slide plate is arranged on the surface of the filling layer, a sealing ring is fixedly connected with the side edge of the slide plate, the sealing ring abuts the inner wall of the apparatus body, a bearing pedestal is arranged at the intermediate part of the slide plate, the air inlet pipe passes through the bearing pedestal and is connected with the bearing pedestal through a silicon seal in a sealing mode; a spring is arranged at top of the bearing pedestal, a communicating pipe is arranged on the side wall at the left side of the apparatus body, and two ends of the communicating pipe are communicated with the apparatus body. The oxidation apparatus greatly prolongs the stay time of air in the apparatus, nitric oxide gas in nitrogen oxide can fully oxidized to nitrogen dioxide, oxidation efficiency is high, and real effectiveness of environment quality detection data is greatly increased.

Description

technical field [0001] The invention relates to an environmental quality analysis instrument, in particular to a nitrogen oxide oxidation device for environmental quality analysis. Background technique [0002] With the rapid development of my country's economy and the acceleration of industrialization, the degree of environmental pollution in our country is becoming more and more serious. Now most of our country has smog weather and acid rain, which shows that our country's environmental pollution It has become more and more serious. [0003] In environmental quality testing, the use of environmental quality analyzers is more common, and environmental quality analyzers can detect various components in the air, such as nitrogen oxides, sulfur dioxide, dust, etc. [0004] When the existing nitrogen oxides are detected, since the nitrogen oxides are mainly composed of nitrogen monoxide and nitrogen dioxide, and the absorption liquid can only absorb nitrogen dioxide, it is nece...

Problems solved by technology

[0005] However, at present, nitrogen oxides are oxidized by nitrogen oxides through the oxidizer tube. The residence time of the gas in the oxidizer tube is short, and the reaction of nitrogen oxides is not complete enough, so that the detected nitrogen oxides are too small and cannot be truly reacted.
