Description
Technical field
The utility model belongs to boiler slag removal technical field, more particularly to a kind of to control deslagging and prevent from spraying slag device.
Background technology
CFBB typically uses low-grade coal, and 0~13mm of coal particle size, ash content is high, and this make it that the grey quantity of slag is larger, ash
About 900 DEG C of slag discharge temperature.Currently, CFBB typically sets slag-drip opening in bottom or side, and lime-ash falls into rolling
Cylinder slag cooler is cooled to 150 DEG C or so deslagginves.At present for the boiler using roller slag cooler, change is usually taken in letting cinder control
Drum rotation speed controls bed drain purge, but often because the change to coal particle size, pressure in the burner hearth can not realize controllable deslagging, part
Often there is spray slag and from flow phenomenon in boiler of power plant.With the increase of CFBB capacity, for Large Copacity recycle stream
Fluidized bed boiler, realizes the performance driving economy important of safety, automatic discharge to boiler.Due to CFBB combustion
With ature of coal and the difference of granularity, hot deslagging mobility is big, flow be difficult to easily cause in effective control, production process deslagging it is not smooth or
Person sprays slag phenomenon, jeopardizes safety in production.Mainly there are Pneumatic type and machinery for the slag-draining device of CFBB both at home and abroad
The class of formula two, the quantity of slag regulation performance of Pneumatic type control device is poor；Easily by slag in tradition machinery formula control device (gate valve) operation
Block is stuck to occur stifled slag and deformation, and operation maintenance is difficult, and the mechanical device design having in addition is unreasonable, finds exist among operation
Lime-ash flows automatically, or even spray slag phenomenon.
The content of the invention
In order to overcome the defect of above-mentioned prior art, it is an object of the invention to provide a kind of slag discharge control device, to solve
Certainly boiler slag removal is discontinuous in the prior art and sprays slag problem.
In order to achieve the above object, the present invention is adopted the following technical scheme that：
Set in a kind of slag discharge control device, including slag inlet 1, the housing 9 connected with slag inlet 1, the housing 9 heat-resisting
Abrasion-resistant blade 7, the drive disk assembly being connected with heat-resistant antifriction blade 7 and motor 4, are arranged on the slag notch 8 of the bottom of housing 9, slag input
The slope for preventing grey slag muck plug from causing lamina idle-run before heat-resistant antifriction blade 7 is done on passage, drive disk assembly and motor 4 are controlled
The rotation of heat-resistant antifriction blade 7, will be scraped to slag notch 8, the structure of heat-resistant antifriction blade 7 is in from the boiler slag removal that slope is slipped into
Hypomere blade is rotatable in the characteristics of now big-and-middle area of area is small up and down, rotary course scrapes lime-ash, when the abnormal lime-ash of deslagging
When flow is big, epimere blade can increase deslagging resistance, prevent boiler spray slag phenomenon, bulk lime-ash can be from upper-lower section blade
Space by avoiding stifled slag, the rotatable parts of drive disk assembly and motor 4 pass through cooling water temperature, it is to avoid equipment overheat is deformed.
Maintenance slide valve 3 and accident slag tap 2 are installed on the slag inlet 1.
During deslagging bite, drive disk assembly and motor 4 can drive heat-resistant antifriction blade 7 to invert, and dredge deslagging pipeline.
Heat-resistant antifriction blade 7 selects ZGCr25Ni20 heat-resisting steels, in 1150 DEG C of continuous work of temperature, with water inlet pipe 10
Device is cooled down with outlet pipe 11, cooling jacket is carried on drive disk assembly and motor 4, is connected with water inlet pipe 10 and outlet pipe 11
Connect.
The top of the housing 9, which is set, is equipped with heat-insulating and sealing part 5 on end cap 6, drive disk assembly and motor 4.
The beneficial effects of the utility model：
1) slag discharge control device can realize effective control to boiler slag removal amount, and the special tectonic of heat-resistant antifriction blade is kept away
Boiler high temperature ash spray slag phenomenon is exempted from, plant and equipment health is obviously improved, and protects operation and the inherently safe of maintainer.
2) apparatus structure that the utility model is related to is simple, will not block up slag, and operation maintenance is convenient.
Brief description of the drawings
Fig. 1 is the side view of the utility model device.
Fig. 2 is the top view of the utility model device.
Wherein：1- slag inlets, 2- accident slag tap, 3- maintenance slide valves, 4- drive disk assemblies and motor, 5- heat-insulating and sealings
Part, 6- end caps, 7- heat-resistant antifriction blades, 8- slag notches, 9- housings, 10- water inlet pipes, 11- outlet pipes.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
As illustrated in fig. 1 and 2, a kind of slag discharge control device, including slag inlet 1, the deslagging of CFBB is from slag input
Mouth 1 enters slag discharge control device, is slided into by slope between heat-resistant antifriction blade 7, in drive disk assembly and the control housing 9 of motor 4
Heat-resistant antifriction blade 7 is rotated, and boiler slag removal is scraped to slag notch 8 and is discharged into again in slag cooler, by adjusting drive disk assembly and electricity
The rotating speed of machine 4 realizes effective control of boiler slag removal amount.Above and below the material selection ZGCr25Ni20 steel of heat-resistant antifriction blade 7, blade
