Nitrogen oxide catalytic reaction net

Abstract

The invention discloses a nitrogen oxide catalytic reaction net, which comprises a reaction net body, wherein the reaction net body is formed by interweaving a plurality of wires, the top portion andthe bottom portion of the reaction net body are respectively provided with a plurality of outward flanges, the outer edges of the flanges contact the inner wall of a reaction pipe, and the wire comprises the following components by mass: 0.02-0.04 part of carbon, 0.3-0.5 part of silicon, 0.1-0.2 part of manganese, 0.0035-0.006 part of sulfur, 56.3-59.2 parts of nickel, 21.2-23.5 parts of chromium,0.15-0.3 part of titanium, 1.23-1.66 parts of aluminum, 0.014-0.031 part of calcium, 0.0003-0.0008 part of boron, and 16.223-16.665 parts of iron. According to the present invention, by improving thestructure and the components of the reaction net, the nitrogen oxide catalytic reaction net has functions of high-temperature resistance, rapid reaction and effectiveness.

Description

technical field [0001] The invention relates to the technical field of reaction nets, in particular to a nitrogen oxide catalytic reaction net. Background technique [0002] Nitrogen oxides, which include compounds such as nitrous oxide (N2O), nitrogen monoxide (NO), nitrogen dioxide (NO2), dinitrogen trioxide (N2O3), dinitrogen tetroxide (N2O4), and dinitrogen pentoxide Nitrogen (N2O5), etc. Except for nitrogen dioxide, other nitrogen oxides are extremely unstable, and turn into nitrogen dioxide and nitric oxide when exposed to light, humidity or heat, and nitrogen monoxide turns into nitrogen dioxide. Exposure in occupational environments is therefore a mixture of several gases commonly referred to as gunpowder (gas), mainly nitric oxide and nitrogen dioxide, with nitrogen dioxide predominating. Nitrogen oxides are toxic to varying degrees. [0003] At present, companies have different treatment methods for nitrogen oxides. At present, there are catalytic reaction nets ...

AI Technical Summary

Problems solved by technology

[0003] At present, companies have different treatment methods for nitrogen oxides. At present, there are catalytic reaction nets to deal with nitrogen oxides, but because this catalytic reaction net cannot withstand high temperatures above 1200°C, at the same time, due to the catalytic The limitation of the structure of the reaction network leads to the distance between it and the flame. The above two disadvantages are not conducive to the progress of the reaction, resulting in low reaction efficiency.
