Description
Technical field
Present invention relates particularly to a kind of fine coal pressurization fluidization conveying device.
Background technology
, it is necessary to carry out Geldart-D particle to coal dust in gasifying powder coal device.The method of existing Geldart-D particle is by coal dust
It is sent to by normal pressure storehouse via transformation storehouse in the cylindrical Pulverized Coal Bin of high pressure.Treat that the coal dust material in high pressure Pulverized Coal Bin reaches high charge level
When, stop charging.Coal dust amount and the nozzle quantity put into operation according to needed for gasification furnace, open corresponding fluidized wind manage-style control valve door
And corresponding discharging control valve, fluidized wind through fluidize airduct enter each independent air compartment, through air distribution plate after to the coal in material issuing tank
Powder is fluidized, and the coal dust after being fluidized is conveyed under the pressure-driven of pressurising wind along discharge nozzle.Introduce supplement wind defeated to adjust
Send solid-gas ratio.Fluidized wind, pressurising wind and supplement wind are directed to, fluidized wind is usually to be passed through in the bottom of high pressure Pulverized Coal Bin,
Coal dust is fluidized, pressurising wind is passed through at the top of high pressure coal bunker, supplement wind is passed through in the side of high pressure coal bunker.Due to three
The pressure of kind of wind is different, be passed through that position is not equal, improves the complexity of powder fluidized system.And in high pressure Pulverized Coal Bin
The amount of coal dust is larger, at the same substantial amounts of coal dust is fluidized, high-pressure delivery when, the requirement to fluidized wind and high-pressure blast is higher,
And it is difficult to even fluidizing and uniform high-pressure delivery.
The content of the invention
Needs are conveyed according to coal dust, attempt to be provided with online pressurization fluidizer, it fluidizes internals using powder sintered
Belong to material, the material is formed by powder sintered, form small through hole, air-flow is passed through from outside, fine coal is fluidized into inner side
Pressurized delivered, the material hardness is high, plasticity is low, fragility is big, due to air-flow differential and gas pressure oscillation, through transporting after a while
There is fragmentation in the row pressurization powder sintered metal internals of fluidizer, and the sintered part of fragmentation is conveyed into fine coal in the presence of air-flow
Pipeline, causes pipeline to block, fine coal supply stops, and ultimately causes system shutdown.
In order to solve technical problem present in above-mentioned prior art, it is an object of the invention to provide a kind of fine coal pressurized stream
Change conveying device, the pressurization fluidizer can realize the online fluidisation of fine coal, fluidized in fine coal course of conveying, fluidized gas is same
When provide fine coal conveying pressure, simplify the structure of air-transport system, and improve fluid effect.And convection current is disguised
