Description
Technical field
The present invention relates to energy-saving and emission-reducing technique in a kind of steel enterprise sintering process, specially a kind of sintering pallet side
Sealing and end seal.
Background technique
Currently, steel enterprise sintering process smoke gas treatment is the most important thing as environmental requirement is more and more tighter.But due to existing
Some sintering process leak out seriously, so that the sintering flue gas amount that need to be handled is huge, greatly improve control expense and the following environmental protection
The operating cost of facility.The patent No. " CN102997667B " " sintering machine side seal device " carries out wiping using band metal plate
Formula sealing, the disadvantage is that: former existing sintering machine trip plate sealing is identical, in the process of running, will generate between the close plate envelope of wiping
Gap leaks into air.The patent No. " CN202869242U " " sintering machine head end tail sealing device " is pacified on roller using roller side by side
It fills ceramic packing to be sealed, but since the trolley supporting beam gap of sintering machine is larger, and the furnace of supporting beam bottom and trolley
Row's depth is larger, and short circuit phenomenon can occur for flue gas, therefore sealing effect is general.A kind of sealing device applied to sintering machine sealing
" CN201721848593 " acts only on the sealing of trolley sideboard, sliding can not be prevented to leak out, and trolley sideboard was producing
Cheng Zhong is influenced by the continually changing temperature of mineral aggregate, will deform, influence sealing effect." CN201110277244 " " sintering
Pusher side portion sealing device ", due to being sealed using sealing plate, in trolley operational process, the sealing plate of trolley is by mine in trolley
Expect that the influence of temperature change, sealing analysis will deform, causes sealing face contact bad, the effect of sealing is poor.Patent
Number " CN201820125109 " " sintering pallet flexible seal device " being slidingly sealed for sealed sintering machine trolley bottom, no
The side and end face of the trolley of energy sealed sintering machine." CN201711082906 " " a kind of seal device of sintering machine pallet and sealing
The same patent No. of method " " CN201820125109 ", is only used for being slidingly sealed for sealed sintering machine trolley bottom.
" a kind of continuous pallettype sintering machine self-lubricating side-sealing device " of " CN201520414262 ", the same to patent No. " CN201820125109 ",
It is only used for being slidingly sealed for sealed sintering machine trolley bottom." the side seal device of sintering machine " patent No.
" CN201110277244 " though being side seal, the sealing of side sealing plate sealing plate in the process of running, not only can due to trolley
It moves left and right, and occurs that temperature distortion occurs due to temperature change, thus cause sealing effect poor, it is more serious
It is the end (trolley disengaging position) of side seal cover, can not be sealed, therefore this sealing device, it cannot be effectively to sintering board
Vehicle is effectively sealed." sealing mechanism with the path formula end seal section " patent No. " CN201220024908 " is to sintering locomotive
It is sealed at wheel, but since, as structure, when wheel passes through diaphragm, diaphragm will be deformed using diaphragm, wheel can not be close to,
To cause to leak out, in practice, the time is not grown, and plastic deformation will occur for diaphragm, to can not seal.It is existing in a word
Technology still have a very big defect to sintering pallet sealing, air leak rate of air curtain is still very serious.The oxygen content in sintering flue gas exists at present
15.5% or more.
