Abstract
The utility model discloses a clear stifled device of thermal power factory high pressure air water coal bunker, including establish nozzle on the coal bunker inner wall, with the nozzle pass through the pipe connection compress air system and water under high pressure system, with the PLC of compress air system and water under high pressure headtotail. The utility model discloses can realize full automation, the operation is safe simple, combination application through high -pressure air water, clear stifled to become initiative defence formula clear stifled by passive the qing dynasty with the coal bunker, can improve the stifled effect of the qing dynasty of coal bunker greatly, and thoroughly the high -efficient thermal power plant's coal bunker of solving blocks up, realizes that the most genuine coal bunker is settleed to block up.
Description
Technical field
The utility model belongs to thermal power plant's BABBbBBvvlockage clearing device for coal bunker, is specifically related to a kind of thermal powerplant high-pressure air-water BABBbBBvvlockage clearing device for coal bunker.
Background technology
In thermal powerplant production run, due to humidity and the granularity problem of feed coal, often can cause silo blockage, take the phenomenons such as arch, and then cause the faults such as coal of breaking to coal mill, impact is normally produced, and seriously can cause unit chaser.For thermal power plant's coal bunker blockage problem, but a lot of power plant takes various method block clearing less effective, major cause is the operating mode of coal dust in coal bunker is a dynamic operation condition, position and the order of severity of blocking of blocking are also different, therefore need to carry out block clearing by the even chemical way cooperation of physics.
The Method of blockage removal of current routine has the means such as manpower block clearing, vibrator, air bubble, respectively has merits and faults: manpower block clearing is exactly that coal is disclosed in coal hole, sledgehammer knocks chute blockage position etc. and carrys out broken block disclosing.Manpower block clearing can only as expedient, and block clearing effect is passable, but the well damage to equipment, there is potential safety hazard.Vibrator, and manually impact substantially identical, the coal be bonded on coal bunker wall is departed from gradually, to reach broken block object by shaking.Because coal bunker blocking position is uncertain, vibrator role is just very limited, and a lot of Installation in Plant vibrator is not dealt with problems later, even occurs that vibrator causes bulkhead to damage, as coal bunker wall shatters.Air bubble power plant use many, utilize the effect of pressurized air momentary pulse directly to impact block part in coal bunker, coal dust flowed under gravity again.Weak point exactly when air bubble be in blocking arch upward position time coal can be made to rush more closely knit and more closely knit.
Utility model content
The purpose of this utility model is to provide a kind of thermal powerplant high-pressure air-water BABBbBBvvlockage clearing device for coal bunker of good blocking cleaning effect.
The thermal powerplant high-pressure air-water BABBbBBvvlockage clearing device for coal bunker that the utility model provides, the PLC comprise the nozzle be located on coal bunker inwall, the compressed air system be connected by pipeline with nozzle and high pressure water system, being connected with compressed air system and high pressure water system.
Described compressed air system comprises storage tank and compressed air regulating valve, and described PLC is connected with described compressed air regulating valve.
Described high pressure water system comprises reserve tank, high-pressure hydraulic pump and high pressure water control cock, and described PLC is connected with high-pressure hydraulic pump and high pressure water control cock.
The beneficial effects of the utility model:
1, thoroughly can efficiently solve thermal power plant's coal bunker blocking, realize coal bunker block clearing truly;
2, can realize full automation, safety of operation is simple;
3, by the united application of high-pressure air-water, coal bunker block clearing is become the block clearing of Initiative Defense formula by passive block clearing, greatly can improve the block clearing effect of coal bunker.
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Thermal powerplant high-pressure air-water BABBbBBvvlockage clearing device for coal bunker as shown in Figure 1, comprise the nozzle 1 of the easy generation block part be located on coal bunker a inwall, 10, nozzle 1, 10 are connected with compressed air system and high pressure water system respectively by pipeline 11, the compressed air regulating valve 2 that compressed air system comprises storage tank 8 and is connected with storage tank 8, 9, high pressure water system comprises reserve tank 4, the high-pressure hydraulic pump 5 be connected with reserve tank 4, 6 and with high-pressure hydraulic pump 5, the 6 high pressure water control cocks 3 connected, 7, compressed air regulating valve 2, 9, high-pressure hydraulic pump 5, 6 and high pressure water control cock 3, 7 are all connected with PLC.
When the situation of blocking knot arch appears in coal bunker, PLC can send instruction, first opens compressed air regulating valve 2,9, compressed-air actuated pressure is 2-10MPa, and impulse rate is 60 times/min, carries out pulsed piping and druming cutting, destroy the leakproofness of bottleneck area, impel coal dust in coal bunker to recover flowing and conveying; After the fixed time of interval, PLC sends instructions and starts high-pressure hydraulic pump 5,6 and open high pressure water control cock 3,7, and hydraulic pressure is 0.8-1.5MPa, and high pressure water carries out impact drainage to coal dust in coal bunker, impels the coal dust of coal bunker under the effect of high pressure water, recover flowing and conveying.Also the susceptible to plugging position of wall can be easily stained with by coal dust in the orderly piping and druming coal bunker of high pressure gas, high pressure water when normal operation, make coal dust to be stained with may dropping to of wall minimum, becoming passive brings down stocks as initiatively bringing down stocks, ensure the normal smooth delivery of power of coal dust, thus actv. ensures the safe and efficient production of power plant.
