According to sintering equipment described in the utility model, wherein the combustion gas injection tube 5 is sealing round tube, axial to hang down
Directly in trolley movement direction, and the semi circular surface of the combustion gas injection tube 5 towards trolley is equipped with fine pores.Further preferably
Ground, in order to make gas be uniformly dispersed, the fine pores number close to the air inlet section of combustion gas injection tube 5 is less than far from air inlet section
Fine pores number.
According to sintering equipment described in the utility model, wherein preferably, the combustion gas supervisor 1 and combustion gas disperser 3 it
Between be provided with flow control valve 2.
According to sintering equipment described in the utility model, wherein described device further includes igniter 4 and distributing device 12, institute
It states distributing device 12 to be placed in above pallet at pan feeding, the igniter 4 is placed in above pallet after distributing device 12.
Further, the pallet sealed bottom and it is equipped with air outlet, the air outlet connects blower 13.
It is this feature of cooling procedure that the utility model, which is based on sintering exhausting process, is mixed into combustion gas when being sintered exhausting, makes
The mixture of coal gas and wind burns in sinter bed, to expand the burning zone of sintering, and when extending the maintenance of sintering liquid phase
Between, infiltrate sintering liquid phase sufficiently with solid phase, to improve the intensity of sinter.On the other hand, it is mixed that sintering can suitably be reduced
The mixed carbon comtent in material is closed, Fossil fuel consumption is reduced, increases the clean gas energy and uses, be also to have very much to pollutant emission is reduced
It helps.
The utility model has the advantage of solving can not drop under the premise of improving sinter quality in sintering production process
The technical problem of low solid fuel consumption.It is used by assisted gas, improves sinter quality, while sinter can also be reduced
Solid fuel consumption reduces Fossil fuel consumption, increases the clean gas energy and uses, is also to have very much side to pollutant emission is reduced
It helps.
