[0044] The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0045] See figure 1 The low-energy sintering flue gas nitrogen oxide emission reduction system of the present invention is mainly composed of a circulating fume hood 1, a circulating fan 2, a circulating flue gas dust collector 3, a mixing valve 4, a mixing air regulating pipe 5, a circulating pipe 6, Baffle valve 7, denitrification dust collector 8, denitrification device 9, dust collector 10, desulfurization device 11, main exhaust fan 12, exhaust chimney 13, high nitrogen oxide concentration area wind box A and low nitrogen oxide concentration area wind box B.
[0046] According to the concentration of nitrogen oxides, this system divides all the exhaust boxes at the lower part of the sintering machine trolley into a high concentration area and a low concentration area. The denitrification dust collector 8 is connected to the wind box A in the high concentration are...
