Embodiment 1
[0049] figure 1 It is a partial top view of the integrated sintering flue gas external circulation system near the flue gas splitter mixer, as shown in figure 1 As shown, the flue gas diversion pipeline includes a ring-cooled flue gas diversion pipeline 16 and a sintering flue gas diversion pipeline 13, and a plurality of flue gas inlet branches are arranged on the two inlet pipelines, and the top of the sintering machine trolley 12 along its A plurality of flue gas splitter mixers 14 are arranged in the direction of travel. For the flue gas splitter mixer 14, a square trumpet-shaped flue gas hood 32 is provided at the lower part, and the first inlet 24 and the second inlet 30 at the upper part are respectively arranged in the flue gas splitter. The number of two opposite sides of the mixer 14 casing increases or decreases according to the actual needs on the spot. The sintering flue gas pipeline 13 and the ring-cooled flue gas pipeline 16 are respectively connected to the ...
Embodiment 2
[0068] In this embodiment 2, the sintering flue gas with high temperature, low sulfur content and relatively high oxygen content is selected to pass into the first inlet 24, and the ring-cooled flue gas with low temperature but high oxygen content is passed into the first inlet 24. 2 entrance 30. The sintering flue gas enters the upper flue gas chamber 26 through the first inlet 24, and then enters the flue gas splitting pipe 27 through the through hole connected to the flue gas splitting pipe 27 on the No. Then enter the positive grid 34, and then enter the lower flue gas chamber 36 through the male grid 34; the ring-cooled flue gas enters the middle flue gas chamber 25 through the second entrance 30 and then enters the negative grid 33, and is decomposed into multiple small airflows Finally, it enters the lower flue gas chamber 36; finally, the ring-cooled flue gas decomposed into multiple small airflows and the sintering flue gas are fully mixed in the lower flue gas chambe...
Embodiment 3
[0081] In this embodiment 3, the annular cooling flue gas with lower temperature but high oxygen content is selected to be passed into the first inlet 24, and five groups of sintered flue gases with high temperature, low sulfur content and relatively high oxygen content at different flow rates are selected. The flue gas enters the second inlet 30, and the five sets of flow velocities are respectively 10m / s, 15m / s, 20m / s, 25m / s, and 30m / s, and the flow velocities increase linearly in turn. The ring-cooled flue gas enters the upper flue gas chamber 26 through the first inlet 24, and then enters the flue gas splitting pipe 27 through the through hole connected to the flue gas splitting pipe 27 on the No. The air flow enters the positive grid 34, and then enters the lower flue gas chamber 36 through the male grid 34; the sintering flue gas enters the middle flue gas chamber 25 through the second inlet 30 and then enters the negative grid 33, where it is decomposed into multiple sma...
