Description
Technical field
The present invention relates to a kind of deashing device, particularly relate to a kind of tubular air preheater impulse dust remover.
Background technology
Giant easily causes air preheater pipeline secondary injury owing to hydraulic pressure is higher, and compressed air is to blocking relatively
Light pipeline has preferable effect, for blocking more serious pipeline DeGrain.Punching is we have invented in conjunction with above 2
Dynamic formula tubular air preheater dust remover.Owing to flue gas cold air outer with stove at air preheater carries out sufficient heat exchange, empty
Air preheater porch flue gas is warm is down to less than 70 DEG C, and easily condensation formation black dirt gathers at this, and long-play is easy
Cause air preheater plugging, have resulted in blocking when economizer is revealed, affect boiler operatiopn, boiler breakdowns time serious, can be caused
Blowing out.Most of power plant use giant or compressed air to clear up.Giant easily causes sky owing to hydraulic pressure is higher
Air preheater pipeline secondary injury, and compressed air has preferable effect to the lighter pipeline of blocking, more serious for blocking
Pipeline DeGrain.
Summary of the invention
It is an object of the invention to provide a kind of it can be avoided that to preheater tube injury, ash-removal effect good tubular air preheating
Device impulse dust remover.
For achieving the above object, the technical solution used in the present invention is: a kind of tubular air preheater impulse dust remover,
Including airduct, airduct two ends are fixedly connected with baffle plate, it is characterized in that: in airduct, cross-under has water pipe, and water pipe is fixing with baffle plate to be connected,
The left end of water pipe is fixedly connected with water pipe head, and the right-hand member of water pipe is fixedly connected with aqueduct shower nozzle, and airduct left part is designed with air intake
Mouthful, airduct right part has gas port, and the right part of airduct is connected by bearing rotating ring, rotating ring and described gas port
Corresponding, the periphery of rotating ring has reaction spray orifice, the right-hand member of rotating ring is fixedly connected with blade, and the right-hand member of blade leads to
Crossing the fixing connection of fixed disc, rotating ring is designed with bleeder port with the left end junction of airduct.
In this structure, described reaction spray orifice is angling hole.
Advantages of the present invention effect is: due to this structure of the present invention, the invention have the advantages that so using, 1,
Extend the service life of air preheater, use giant to clear up in the past, every time cleaning rear section air preheater
Pipeline wall thickness 1.5mm is damaged, and black dirt is only moistened by this device with a small amount of low setting-out, does not has any injury to pipeline；
2, wet blasting is in hgher efficiency, and black dirt is under the washing away of water, and intensity step-down, cleaning efficiency is higher.3, compressed air cleaning is permissible
The surrounding dust stratification cleaning making tube wall is more thorough, and the mixture of water and air forms bubbling in air preheater pipe, can be in time
Outside discharge pipe；4, operation is more laborsaving, and the external force produced wind and water due to dust remover self is balanced, it is simple to worker is on-the-spot
Operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the A direction view of Fig. 1；
Fig. 3 is the B-B sectional view of Fig. 1.
In accompanying drawing: 1, water pipe head；2, air inlet；3, airduct；4, bleeder port；5, reaction spray orifice；6, gas port；7, axle
Hold；8, aqueduct shower nozzle；9, blade；10, fixed disc；11, annulus is turned；12, water pipe.
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings:
As shown in Figure 1, 2, 3, a kind of tubular air preheater impulse dust remover, including airduct 3, airduct 3 liang for the present invention
End is fixedly connected with baffle plate, it is characterized in that: in airduct 3, cross-under has water pipe 12, and water pipe 12 is fixing with baffle plate to be connected, a left side for water pipe 12
End is fixedly connected with water pipe head 1, and the right-hand member of water pipe 12 is fixedly connected with aqueduct shower nozzle 8, and airduct 3 left part is designed with air inlet 2,
Airduct 3 right part has gas port 6, and the right part of airduct 3 is connected by bearing 7 rotating ring 11, and rotating ring 11 is with described
Gas port 6 is corresponding, and the periphery of rotating ring 11 has reaction spray orifice 5, and the right-hand member of rotating ring 11 is fixedly connected with blade
9, the right-hand member of blade 9 connects by fixed disc 10 is fixing, and rotating ring 11 is designed with bleeder port with the left end junction of airduct 3
4.In the present embodiment, described reaction spray orifice 5 is angling hole.
When using the present invention, the present invention is placed in preheater tube, connects wind regime at air inlet, connect water in water pipe head
Source, source pressure is less than 0.2Mpa, and compressed air pressure is less than 0.3Mpa, and such water is sprayed from aqueduct shower nozzle by water pipe head
Water, the black dirt softening, cutting in moistening tubular air preheater, another road compressed air is in air inlet enters airduct, so
After enter rotating room through gas port, by the effect of reaction spray orifice drive the bearing that is fixed on airduct be rotated annulus and
The assembly of blade rotates together with, and the recoil discharging spout generation from water pipe can be filled by the air simultaneously discharged from bleeder port
Divide and offset.
After water moistens black dirt, utilize the compressed air rotating ring that is fixed on tube wall of impulsion drive on front side of blade rotate
On the one hand the black dirt after cleaning is moistening, on the other hand can arrange the unnecessary black dirt after cleaning, the mixture of water and air in time
Go out, the tube wall of air preheater can be cleaned from reaction spray orifice simultaneously.From the bleeder port between airduct and rotating ring
The recoil that expellant gas produces after balancing pipeline ejection water.In the process the pressure of water need not the highest can be right
Tube wall is protected, and does not results in secondary injury.
Existing two 75t/h CFBB JG 75/5.3 MQ of Gangue Power Plant and 130 t/h spoil and
CFBB JG 130/5.3 MQ of coal slime multifuel combustion is tubular air preheater, after blowing out in deashing process
The impulse tubular air preheater dust remover working time is used to be shortened to 4 hours by original 16 hours, air preheater
Service life was extended for present 6 year by original 3 years, and during deashing accomplished air preheater during shutdown maintenance
Zero injury, after deashing, the plugging rate of air preheater is substantially reduced, and boiler negative pressure keeps preferably, and boiler operatiopn is stable, and boiler is born
Lotus keeps specified operation for a long time.
