Summary of the invention
The invention provides one for problem above and both improved raw meal powder dispersion effect, improve the heat exchange of pre-heating system
Efficiency, reduces again the preheater multiple spot blanking system of collapse material, putty situation.
In order to solve above technical problem, the invention provides a kind of preheater multiple spot blanking system, including tremie pipe, under
Material pipe includes main pipeline and n the subtube being connected on main pipeline, wherein n >=2；On m subtube, set the most successively
Having weight flap valve, expansion joint, spreading case, spreading case is connected with gas passage, wherein 1≤m≤n；
Remaining n-m subtube, is sequentially provided with slide valve, weight flap valve, expansion joint, spreading case from top to bottom, spreads
Hopper is connected with gas passage；Now the joining place at main pipeline and subtube is provided with material distributing valve；Tremie pipe and cyclone cylinder tapering
Being connected, spreading case is arranged in short transverse same level.
Described spreading case can be evenly arranged on the circumferencial direction of gas passage, it is also possible to nonuniform mutation operator, but is
The material dispersion effect that guarantee is optimal, is evenly arranged as best mode, material dispersion can be made more uniform, with gas passage
Air-flow heat exchange the most from below to up is more abundant, is greatly improved the heat exchange efficiency of preheater decomposition furnace system.
As a modification of the present invention, described subtube centrage is more than or equal to 40 ° of (materials with the angle of horizontal plane
Natural packing angle), preferably 60 ° can further be improved blocking-proof result, and blocking-proof result is good, and are conducive to setting of this system
Count, manufacture and install.
Described material distributing valve can use electro-hydraulic ejector half material distributing valve, or air-driven type material distributing valve, or type hand material distributing valve.
As a modification of the present invention, be provided with high temperature resistant castable at main pipeline and subtube inwall, main pipeline and point
The part (such as the axle etc. of weight flap valve) that castable that pipeline is high temperature resistant can not be protected uses heat resisting steel material, uses high temperature resistant
Castable and heat-resisting steels mass-energy effectively extend pipeline and conduit component (such as material distributing valve, slide valve, weight flap valve, expansion
Joint and spreading case) service life.
The material come from whirlwind cone subordinate passes sequentially through tremie pipe, weight flap valve, expansion joint and spreading from top to bottom
Case enters gas passage, mixes with air-flow from bottom to up in gas passage；Or pass sequentially through tremie pipe, material distributing valve, flashboard
Valve, weight flap valve, expansion joint and spreading case enter gas passage, mix with air-flow from bottom to up in gas passage.
Slide valve is arranged on the lower section of material distributing valve, and the effect as material distributing valve supplements, and material distributing valve can be played guarantor
Protect effect；Weight flap valve is arranged on the lower section of slide valve, and when there being material to pass through, the valve plate of weight flap valve is opened, and is not having
When having material to pass through, the valve plate of weight flap valve is closed, and stops hot blast to pass through from bottom to up, plays air locking function；Expansion joint sets
Put the below or above at weight flap valve, be used for compensating system expanded by heating.
Present system is multiple spot blanking, by several subtubes, the material in tremie pipe is carried out blanking respectively, simultaneously
Under on the diverse location of gas passage circumferencial direction, thus improve the technological operation to preheater decomposition furnace system and heat exchange
Efficiency, and decrease the material that collapses, the generation of putty phenomenon.
