Abstract
The present invention provides a kind of circle fluidized-bed gasification furnace air distribution plate, belongs to the special-purpose member of coal gasification apparatus.It is that air distribution plate is made of nonmetallic exotic material, and underside shape is fovea superior hollow spherical crown.Air distribution plate is provided with several passages, and passage is set to epimere vertical holes, stage casing lateral aperture, hypomere vertical holes, and stage casing lateral aperture is sealing cap.Gasifying agent in air chamber enters the furnace chamber of circle fluidized-bed gasification furnace along passage hypomere vertical holes, stage casing sealing cap, epimere vertical holes, and the blast cap in passage stage casing carries precipitum in furnace chamber, and the precipitum circulation in blast cap is blown into furnace chamber.The present invention makes air distribution plate using nonmetallic exotic material, solves the problems, such as that traditional air distribution plate is involved great expense using refractory metal material；The lateral aperture that passage stage casing is set instead of traditional blast cap, overcome to the problem that solid-phase material is leaked into air chamber.
Description
Technical field
The present invention relates to a kind of circle fluidized-bed gasification furnace air distribution plate, and in particular to what a kind of nonmetallic materials made is provided with
The air distribution plate of built-in sealing cap, more particularly to sealing cap are arranged on the air distribution plate in vent cap.Belong to the special portion of coal gasification apparatus
Part.
Background technology
Air distribution plate is one of important component of circle fluidized-bed gasification furnace, and it is the base plate of gasification furnace burner hearth, and its top is
Burner hearth, bottom is connected with air compartment.The effect of air distribution plate is to support the material in gasification furnace burner hearth, while making the gas in the air compartment of bottom
Body is flowed uniformly across from the whole region of air distribution plate, into burner hearth.People generally use and set substantial amounts of in air distribution plate outlet side
Then blast cap, the gas allowed in air chamber spray from the aperture of blast cap and enter gasification furnace burner hearth again even into blast cap, realizes
Resistance is small in gas flow, the good purpose of cloth wind uniformity.But there is a problem of that leakage ash is serious, i.e., particle diameter is smaller in burner hearth
Solid-phase material easily propagate through aperture and leak into air chamber.On the one hand the loss of solid-phase material is caused, is on the other hand also easy to cause wind
The abrasion in locular wall face, when serious, air compartment is blocked full and forces gasification furnace out of service.To find out its cause, being setting for grid plate hood
Put mode and there is more serious deficiency, be first because being interfered with each other between grid plate hood stomata, solid formation being blown into other side
Stomata and enter air inlet chamber, second be grid plate hood ad hoc structure cause solid-phase material to be moved in air distribution plate stomata can not be inverse
To.Therefore design it is a kind of can lift the ventilative uniformity of air distribution plate, solid-phase material is leaked into preventing fluid bed burner hearth again
The air distribution plate of air chamber is the crux for solving the above problems.
The content of the invention
In order to overcome in background technology, solid-phase material enters the scarce limit of air inlet chamber through air distribution plate in furnace chamber, and the present invention proposes one
Plant circle fluidized-bed gasification furnace air distribution plate.The present invention prevents furnace chamber while realizing that cloth wind is uniform, gas flow resistance is small
Interior solid-phase material leaks into air chamber.
The present invention is implemented using following technical scheme, gasification furnace, air chamber, air distribution plate, and gasification furnace top is furnace chamber, and middle part sets
There is air distribution plate, bottom is provided with air chamber, and the air distribution plate uses nonmetallic exotic material, and underside shape is fovea superior hollow ball
Hat, air distribution plate is provided with several passages, and passage is set to three sections, its epimere be vertical holes, stage casing be lateral aperture, under
Section is vertical holes, and passage stage casing lateral aperture is sealing cap, and the blast cap in passage stage casing carries precipitum in furnace chamber, in air chamber
Gas enter furnace chamber through the passage of air distribution plate from the hollow spherical crown of the lower surface fovea superior of air distribution plate, and by the sedimentation in blast cap
Thing circulation is blown into furnace chamber；
The air distribution plate is one overall with gasification furnace furnace wall；
The air distribution plate is split independent mutually with gasification furnace furnace wall, and with each other using bonding；
The passage is arranged to labyrinth；
The passage stage casing is arranged to oblique.
The present invention makes air distribution plate using nonmetallic exotic material, solves traditional air distribution plate using refractory metal material
The problem that material involves great expense；The lateral aperture that passage stage casing is set instead of traditional blast cap, that is, be designed to built-in sealing cap, overcome
Traditional blast cap is to the problem that solid-phase material is leaked into air chamber.
