Abstract
The invention relates to an air distribution and deslagging device of a fluidized bed boiler and the fluidized bed boiler. The air distribution and deslagging device comprises a plurality of horizontally arranged air pipes, wherein a plurality of open pores for exhausting air are formed in each air pipe along the length direction of the air pipe; each open pore is provided with an air cap; and at least one ash hopper is arranged below the plurality of air pipes. After the air distribution and deslagging device is improved, a large object can automatically fall from the ash hopper, accumulation is not caused, and poking slag by operating personnel is not needed, so that the labor intensity of the operating personnel is relieved, and the scald accident caused by poking the slag is avoided. No accumulation on the bed surface can be caused, the fluidization of the boiler is normal, and the added fuel coal is reduced, so that the consumption of coal is greatly reduced, and more than 5000 tons of coal can be saved by each boiler every year. No accumulation is generated by the boiler, and the operation period is prolonged, so that the starting/stopping frequency of the boiler is reduced, the starting/stopping expense of the boiler is reduced, and the cost is greatly reduced.
Description
Technical field
The present invention relates to cloth wind slag-draining device and the fluidized-bed combustion boiler of a kind of fluidized-bed combustion boiler.
Background technology
In the prior art, the bed surface of fluidized-bed combustion boiler is made up of air distribution plate and blast cap, air distribution plate
On be provided with multiple slag-discharge pipe, generally by 3 slag-discharge pipes, foreign material bigger in operation not can from
Dynamic discharge, will pile up for a long time, causes boiler fluidisation bad, is forced blowing out and processes.Significantly
Shorten the cycle of operation of boiler.Technological deficiency causes the boiler operatiopn cycle short, the most at present
Blowing out the foreign material such as bed surface iron wire will be cleared up more than 30 days.
Summary of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, it is provided that Yi Zhongliu
The cloth wind slag-draining device of fluidized bed boiler and fluidized-bed combustion boiler.
For solving above technical problem, the present invention adopts the following technical scheme that:
A kind of cloth wind slag-draining device of fluidized-bed combustion boiler, it includes the airduct of multiple horizontal arrangement,
On each described airduct, the length direction along airduct is provided with the multiple perforates for air draft, institute
It is provided with blast cap in the perforate stated, below described multiple airducts, is provided with at least one ash that falls
Bucket.
Preferably, described multiple wind-distributing pipes extend longitudinally, and multiple wind-distributing pipe is arranged in parallel.
Preferably, described ash dropping hopper has upper opening and lower openings, described ash dropping hopper
The funnel-form that big lower openings is little in upper opening.
Preferably, the valve that can control to open or close it is provided with at described lower openings.
Preferably, the airduct described in each two is arranged with an ash dropping hopper, described ash dropping hopper
Upper opening the downside of described airduct is covered.
Preferably, many 8 wind-distributing pipes arranged in parallel and setting on described cloth wind slag-draining device
4 ash dropping hoppers under wind-distributing pipe.
The present invention also provides for a kind of fluidized-bed combustion boiler, and described boiler includes described cloth wind row
Slag device, described cloth wind slag-draining device is arranged on the downside of the combustion chamber of described boiler.
Due to the employing of above technical scheme, the present invention compared with prior art has the most excellent
Point:
After transforming burner hearth, big object can drop voluntarily from ash dropping hopper, does not produce accumulation,
Need not operations staff and disclose slag, alleviate the labour intensity of operations staff, it is to avoid disclose slag and scald
Accident occur.Bed surface will not produce accumulation, and boiler fluidisation is normal, adds fire coal and reduces, greatly
Reducing greatly coal consumption amount, every stove can save coal more than 5000 tons every year.Boiler is not
Producing and pile up, the cycle of operation extends, and reduces boiler start/ stop number of times, decreases boiler start/ stop expense
With, it is greatly saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cloth wind slag-draining device of fluidized-bed combustion boiler of the present invention,
1, ash dropping hopper；2, wind-distributing pipe；3, blast cap.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further details.Should be understood that this
A little embodiments are for the general principle of the present invention, principal character and advantage are described, and the present invention
Do not limited by the scope of following example.The implementation condition used in embodiment can be according to specifically
Adjustment further is done in requirement, and not marked implementation condition is usually the condition in normal experiment.
It is illustrated in figure 1 the cloth wind slag-draining device of a kind of fluidized-bed combustion boiler described herein, it
Including the airduct of multiple horizontal arrangements, on each described airduct, the length direction along airduct is arranged
There are the multiple perforates for air draft, described perforate is provided with blast cap 3, described multiple wind
At least one ash dropping hopper 1 it is provided with below pipe.Described multiple wind-distributing pipes 2 extend longitudinally,
And multiple wind-distributing pipe 2 is arranged in parallel.Described ash dropping hopper 1 has upper opening and lower openings,
Described ash dropping hopper 1 funnel-form that big lower openings is little in upper opening.Described lower openings
Place is provided with the valve that can control to open or close.Airduct described in each two is arranged with one
Ash dropping hopper 1, the downside of described airduct is covered by the upper opening of described ash dropping hopper 1.Institute
Many 8 wind-distributing pipes 2 arranged in parallel and be arranged on wind-distributing pipe 2 on the cloth wind slag-draining device stated
Under 4 ash dropping hoppers 1.The present invention also provides for a kind of fluidized-bed combustion boiler, and described boiler includes
