Existing fluidized-bed combustion boiler bottom plenum deslagging all uses the direct deslagging of Residue extraction pipeline.In actual operation, because of rubbish
Rubbish type is more, and larger sundries is difficult to be automatically drained out by gravity.The process of direct deslagging be easy because not into
Row classification and cause to burn it is uneven, in clinker solid particle it is uneven and generate block up slag phenomenon shortened so as to cause blowing out
The cycle of operation of boiler.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of for fluidizing to provide
The air pipe device of bed boiler.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of air pipe device for fluidized-bed combustion boiler includes the ventilation duct on the outside of Residue extraction pipeline, it is characterised in that：
The ventilation duct includes entering the wind transverse tube and mounted on transverse tube both ends are entered the wind and relatively parallel guide duct, entering the wind transverse tube lower end and open
There is air inlet；The guide duct is equipped with the one's intention as revealed in what one says of leading of several equidistant arrangements, and each air guide hole is equipped with deslagging air hose, deslagging wind
Pipe includes epimere pipe and the hypomere pipe being connected with epimere pipe, and epimere pipe one end is provided with gas outlet, hypomere pipe one end and air guide hole
It is fixedly connected, epimere pipe is mounted on Residue extraction pipeline and gas outlet is located in Residue extraction pipeline.
Further, the deslagging air hose on a guide duct is staggered and phase with the deslagging air hose on another guide duct
To setting.Staggered deslagging air hose can increase the utilization rate to air draft, accelerate that while slag slagging channel can be made
It is interior that lime-ash keeps fluidized state, it prevents from blocking slagging channel because particle deposits.
Further, angle is in 75 ° between the epimere pipe and hypomere pipe.75 ° of angles enable gas outlet along level side
To downward but not vertical ventilation, so that air draft is blown into deslagging air hose with better angle, air draft is made to be come into full contact with clinker,
Improve slag efficiency.
Compared to the prior art the utility model, has the following advantages and effect：It is simple in structure, it is easy for installation, pass through volume
Air draft is added on the basis of original gravity deslagging in the air pipe device of outer setting, accelerates slag；Both sides deslagging air hose hands over air draft
Mistake is blown into slagging channel, the lime-ash in slagging channel can be made to keep fluidized state, to prevent blocking row because particle deposits
Slag channel improves the cycle of operation of boiler.

Attached drawing described herein is used for providing further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please do not constitute the improper restriction to the application for explaining the application.
Specific implementation mode
It is understandable in order to enable the above objects, features, and advantages of the utility model to become apparent, it is right below in conjunction with the accompanying drawings
Specific embodiment of the present utility model is described in detail.
Embodiment.
As shown in Figs. 1-3, the present embodiment includes being located at 1 outside of Residue extraction pipeline in fluidized-bed combustion boiler and surrounding Residue extraction pipeline 1
Ventilation duct 2, ventilation duct 2 includes air inlet transverse tube 3 and guide duct 4.Air inlet transverse tube 3 is located at 1 one end of Residue extraction pipeline, enters the wind transverse tube
3 lower ends are provided with air inlet 31, and air inlet 31 connects with external exhaust apparatus 6.External exhaust apparatus 6 passes through air inlet after making wind
Air draft is sent into air pipe device by mouth 31.
Two guide ducts 4, which are mounted on, enters the wind 3 both ends of transverse tube, parallel between two guide ducts 4.It is provided on each guide duct 4
Several equidistant arrangements lead one's intention as revealed in what one says 41, and each air guide hole 41 is equipped with a deslagging air hose 5.Deslagging air hose 5 include epimere pipe 51 with
And hypomere pipe 52.52 one end of hypomere pipe is fixedly connected with air guide hole 41.51 one end of epimere pipe is fixedly connected with hypomere pipe 52, another
End is provided with gas outlet 53.Epimere pipe 51 is mounted on Residue extraction pipeline 1, and 51 front end of epimere pipe is located in the cavity of Residue extraction pipeline 1.Its
In, angle is in 75 ° between epimere pipe 51 and hypomere pipe 52, and set 75 ° of angles enable 535 certain angle of gas outlet to send downwards
Wind rather than vertical ventilation or horizontal blast, are enable air draft to be blown into Residue extraction pipeline 1 with better angle, make air draft and clinker
It comes into full contact with, improves slag efficiency.
In the present embodiment, the deslagging air hose 5 on one end guide duct 4 and phase between the deslagging air hose 5 on other end guide duct 4
