Description

Technical Field

[0002] There are two main types of flue gas denitrification technology: dry method and wet method. Compared with wet flue gas denitrification technology, the main advantages of dry flue gas denitrification technology are: low basic investment, simple equipment and process, high efficiency of removing NOX, no wastewater and waste treatment, not easy to cause secondary pollution, the process of removing nitrogen oxides from combustion flue gas, the importance of preventing environmental pollution, flue gas denitrification refers to reducing the generated NOX to N2, thereby removing NOX from the flue gas. According to the treatment process, it can be divided into wet denitrification and dry denitrification. Some domestic and foreign researchers have also developed a method for treating NOX waste gas with microorganisms. Since more than 90% of NOx in the flue gas discharged from the combustion system is NO, and NO is difficult to dissolve in water, the wet treatment of NOx cannot be treated by simple washing method. The principle of flue gas denitrification is to oxidize NO into NO2 with an oxidant, and the generated NO2 is then absorbed by water or alkaline solution to achieve denitrification.

[0003] In the prior art, when detecting the denitrification of flue gas concentration, since the flue gas is always in a flowing state, the existing detection device cannot fix it in one place, making it inconvenient to detect it, resulting in errors in the detection results. Utility Model Content
