Abstract
The invention relates to a totally-enclosed cold slag bucket of large boiler. The prior cold-slag bucket technique has two types of water slag bucket and dry slag bucket, wherein (1) the water slag bucket is that when the boiler is normally running, the flameout water is stored in the slag bucket and the hot furnace slag drops to the cold slag bucket slot through the furnace bottom water-sealing system and the red slag is output by bailing machine after quenching and corning of water, (2) the dry slag bucket is that when the boiler is normally running, hot furnace slag drops directly to the conveying steel-band of the steel-band slag conveyer in the cold slag bucket and cooled down by cool air with the slow moving of the conveying steel-band, and the cool air is heated while heat exchanging and conveyed to the furnace, the furnace slag is conveyed out by steel-band slag conveyer. The product comprises a casing 1 with a group of sealing plates 2 with blocks 3 and a group of tracks 4, the block 3 roll in the track 4, and one end of the sealing plate is connected with power device 5. The product is applicable to the boiler of coal-fired power plant and the similar boilers.
Description
Technical field:
The present invention relates to a kind of large-sized boiler totally-enclosed slag cooling bucket, be used for the boiler of coal-fired power plant.
Background technology:
Existing slag cooling bucket technology has grain slag bucket and dried slag bucket dual mode: (1). and the grain slag bucket is that boiler is when normally moving; the completely flame-out water of storage in the grain slag bucket; hot slag is in the furnace bottom seal water system falls into the cell body of slag cooling bucket, and red slag is exported by dragveyer after the quenching granulation of water.Its shortcoming is: (2). dried slag bucket is that boiler is when normally moving, hot slag is directly fallen on the conveying steel band of the steel band type slag conveyer in the slag cooling bucket, along with moving by cold air, cools off gradually the low speed of carrying steel band, cold air enters burner hearth after being heated in this heat transfer process, slag is sent through the steel band slag conveyer.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly can make sealing plate pull in housing, finish the large-sized boiler totally-enclosed slag cooling bucket of boiler bottom sealing and deslagging.
Above-mentioned purpose realizes by following technical scheme:
Large-sized boiler totally-enclosed slag cooling bucket, its composition comprises: housing, the sealing plate of one group of band pulley is housed in the described housing, and be fixed with one group of slideway in the described housing, described pulley rolls in described slideway, and described sealing plate one end is connected with power set.
Above-mentioned large-sized boiler totally-enclosed slag cooling bucket is fixed with the sealing plate slag scraper in the described housing, described sealing plate lower end is fixed with the slideway slag removing spade.
Above-mentioned large-sized boiler totally-enclosed slag cooling bucket, described housing outside is provided with seal, and described housing outer wall and described seal constitute tank.
This technical scheme has following beneficial effect:
1. one group of sealing plate has been installed in the enclosure, the hot lime-ash that falls after the boiler combustion all can be undertaken on the sealing plate of upper strata, and make the heat of lime-ash itself under without the state that cools off, obtain more effective recycling continuing heating on the sealing plate of upper strata, and can seal burner hearth bottom fully and remain the temperature of boiler slag-cooling bucket identical with the temperature of lime-ash.Lower floor's sealing plate can be accepted the lime-ash that the upper strata sealing plate falls, and keeps burner hearth not contact with extraneous low-temperature receiver before the playback of upper strata sealing plate, guarantees the sealing fully of boiler bottom.
2. the present invention can be converted to thermal source with the low-temperature receiver of boiler, reclaims the rudimental energy of warm sludge, reduce simultaneously boiler leak out a little and during boiler slag removal to the disturbance of boiler combustion generation, the stability of boiler combustion is improved, coa consumption rate obtains descending, and it is energy-conservation to have realized economizing on coal, and improves power plant's benefit.

The specific embodiment:
Embodiment 1:
Large-sized boiler totally-enclosed slag cooling bucket, its composition comprises: housing 1, the sealing plate 2 of one group of band pulley 3 is housed in the described housing 1, and be fixed with one group of slideway 4 in the described housing 1, described pulley 3 rolls in described slideway 4, and described sealing plate 2 one ends are connected with power set 5.
Embodiment 2:
Above-mentioned large-sized boiler totally-enclosed slag cooling bucket is fixed with sealing plate slag scraper 7 in the described housing 1, and described sealing plate 2 lower ends are fixed with slideway slag removing spade 6.
Embodiment 3:
Above-mentioned large-sized boiler totally-enclosed slag cooling bucket, described housing 1 outside is provided with seal 8, and described housing 1 outer wall and described seal 8 constitute tank 9.
The course of work is described:
Above-mentioned large-sized boiler totally-enclosed slag cooling bucket, the tank 9 on this machine top is connected with the annular water seal opotism 10 of boiler furnace bottom, and this machine bottom is connected with boiler slag removal device 11.When boiler normally moved, upper strata sealing plate and lower floor's sealing plate all were in closed state, and as shown in Figure 4, the hot lime-ash in the stove is directly fallen on the upper strata sealing plate of this machine; (or set when reaching the time of setting by the time) upper strata sealing plate is extracted out when the hot lime-ash on the sealing plate of upper strata reaches a certain amount of, and the hot lime-ash on the sealing plate of upper strata is scraping under the effect of sealing plate slag scraper on lower floor's sealing plate, as shown in Figure 5; After the hot lime-ash on the sealing plate of upper strata falls to the greatest extent, be returned to sealing state, wait for the fall accumulation once more of slag of boiler, as shown in Figure 6; After the upper strata sealing plate was returned to sealing state fully, lower floor's sealing plate was extracted out, as shown in Figure 7, makes the hot lime-ash on it fall to falling once more in the disintegrating slag slag-draining device 11.Lower floor's sealing plate is returned to sealing state and waits for that the lime-ash on the sealing plate of upper strata falls once more after the lime-ash on lower floor's sealing plate falls to the greatest extent, as shown in Figure 4.Upper and lower layer sealing plate is in the state that replaces the slag that falls all the time, and perhaps upper and lower layer sealing plate all is in closed state, and perhaps upper and lower layer sealing plate has one to be in the extraction state.When boiler was in exceptional operating conditions, upper and lower layer sealing plate can be in the extraction state simultaneously, as shown in Figure 8, boiler furnace 12 and disintegrating slag slag-draining device 11 directly is communicated with.
