Embodiment Construction
[0036] The following is attached Figure 1-5 The application is described in further detail.
[0037] The embodiment of the present application discloses a high-efficiency denitrification system. refer to figure 1 , figure 2 , the high-efficiency denitrification system includes an air preheater 1 and an SCR reactor 3, wherein the air preheater 1 includes a shell 14 and a plurality of air pipes 16 placed in the shell 14, and the shell 14 is divided by a partition 15 There are three high-temperature zones 11, medium-temperature zone 12 and low-temperature zone 13 arranged in sequence. The flue gas is distributed in each temperature zone, and the air duct 16 is filled with cold air to cool down the flue gas in each temperature zone.
[0038] like figure 1 As shown, the entrance of the high temperature zone 11 is connected with a flue gas input channel 51, the high temperature zone 11 communicates with the medium temperature zone 12 through the through hole 17, and the outlet...

Description
technical field [0001] This application relates to the field of flue gas denitrification technology, in particular to a high-efficiency denitrification system. Background technique [0002] China is rich in coal resources, and most of them are used by direct combustion methods, such as thermal power generation. In the combustion of coal, a large amount of nitrogen oxides NOx will be produced. If this gas is directly discharged into the atmosphere, it will produce highly corrosive acid rain. nitrogen) treatment. [0003] Among the existing denitrification methods, there are selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR). A selective reduction reaction is produced, and finally non-polluting nitrogen and water vapor are produced. The difference between the two methods is that SNCR is generally carried out in a boiler with a higher temperature (800-1200°C) because it does not have the help of a catalyst; while SCR uses a catalyst in the flue,...
