Abstract
The invention relates to a coke-removing device for coke dry quenching. The coke-removing device comprises a gate valve (2) and a feeder (4). The coke-removing device is characterized in that a chute (3) is arranged between the gate valve (2) and the feeder (4); the chute (3) is provided with a pipe (6) connected with a secondary dust remover inlet of the coke dry quenching; the pipe (6) is preferably provided with a regulating valve (7) and a settling chamber (8); the feeder (4) is preferably provided with a dust removal pipe (9). According to the coke-removing device, recycle gas released from the chute (3) is absorbed back to a circulatory system through the pipe (6) by virtue of negative pressure at the secondary dust remover inlet, so that the recycle gas can not be leaked to the air; and occasionally leaked recycle gas is sucked away by the dust removal pipe (9) on the feeder (4). By omitting a rotary sealing valve in a conventional coke-removing device, the coke-removing device provided by the invention reduces construction cost and is simple in structure and low in failure rate, thereby reducing maintenance workload and cost.
Description
Technical field the present invention relates to a kind of discharging device for coke of dry coke quenching, i.e. coke discharger in coke-oven plant's dry quenching(of coke) device.
Coke discharger in the current coke-oven plant of background technology dry quenching(of coke) device has generally adopted the mode of the continuous coke discharging of rotary seal valve, its equipment mainly comprises: slide valve, vibratory feeder, rotary seal valve etc., the dry coke put out in stove leans on gravity fall, enter the rotary seal valve through slide valve, vibratory feeder, then be discharged on conveying belt, the dry malleation recycle gas put out in stove mainly seals by the rotary seal valve.In day-to-day operation, the rotary seal valve often can not be turned round by too much coke or the foreign matter block entered once in a while, need to shut down to process, thereby this kind of coke discharging mode failure rate is higher.In addition, the rotary seal valve is expensive, also needs regularly to return factory maintenance, thus laid down cost and the later maintenance expense all very high.
Summary of the invention the purpose of this invention is to provide a kind of discharging device for coke of dry coke quenching, and this device has been cancelled the rotary seal valve, thus just eliminated the machine halt trouble caused because of rotary seal valve blocking, and greatly reduced laid down cost and later maintenance expense.The object of the present invention is achieved like this: between slide valve and coke discharging material feeder, be provided with chute, chute is provided with pipeline and is connected with the secondary filter entrance of dry coke quenching, on this pipeline, variable valve and settling pocket can also be set, can also be provided with cleaning shaft and be connected with fly-ash separator on material feeder.This device relies on the negative pressure of secondary filter ingress that the recycle gas leaked out in chute is sucked back in the recycle system, makes that recycle gas is unlikely to be leaked in atmosphere, has guaranteed sealing effectiveness.The effect of variable valve is the suction pressure of regulating in pipeline, and the pressure that makes the material feeder place is zero.The effect of settling pocket is that ducted large grain coke powder is settled down, and prevents its blocking pipe or enters secondary filter.In order to collect once in a while the recycle gas that leaks and the dust of discharging point, also be provided with cleaning shaft and be connected with the environmental dust removal device on material feeder.This device is due to the rotary seal valve of having cancelled in traditional discharging device for coke, thus not only reduced laid down cost, and simple in structure, failure rate is low, reduced maintenance workload and expense.
Appended drawings is the principle schematic (broken section) of the embodiment of proposition according to the present invention.In figure, (1) is the dry stove that puts out, and (2) are slide valves, and (3) are chutes, (4) be material feeder, (5) are conveying belt, and (6) are the pipelines be connected with the secondary filter entrance, (7) be variable valve, (8) are settling pockets, and (9) are cleaning shafts.
Embodiment in the present embodiment, slide valve (2) is arranged at dry bottom of putting out stove (1), be provided with chute (3) between slide valve (2) and material feeder (4), chute (3) is provided with the pipeline (6) be connected with the secondary filter entrance of dry coke quenching, pipeline (6) is provided with variable valve (7) and settling pocket (8), also is provided with the cleaning shaft (9) be connected with the environmental dust removal device on material feeder (4).Secondary filter and environmental dust removal device are all the major equipment in the dry quenching(of coke) device, not shown in FIG..During normal operation, coke enters into chute (3) from dry bottom of putting out stove (1) through slide valve (2), then passes through material feeder (4) and be discharged on conveying belt (5) and transport.The dry recycle gas put out in stove (1) is malleation, must be from chute (3) in the gap of coke toward external leakage, but because the pipeline (6) be connected with the secondary filter entrance is negative pressure, so the gas of the inner leakage of chute (3) will be sucked back in secondary filter by pipeline (6), then enters the recycle system.In order to regulate easily pressure, be provided with variable valve (7) on pipeline (6).In order to prevent large grain coke powder blocking pipe or to enter secondary filter, also be provided with settling pocket (8) on pipeline (6).In order to collect once in a while the recycle gas that leaks and the dust of discharging point, also be provided with cleaning shaft (9) and be connected with the environmental dust removal device on material feeder (4).In order to prevent that large lump coke is inhaled in pipeline (6), can install fence or woven wire (not shown in FIG.) between chute (3) and pipeline (6).
Chute in the present embodiment (3) is in operation and has been full of coke always, the inhibition of coke has slowed down leaking of recycle gas, and the most of recycle gas leaked is inhaled into secondary filter by pipeline (6), the recycle gas that leaks into once in a while material feeder (4) is collected by cleaning shaft (9) by the environmental dust removal device.So the present embodiment has omitted the rotary seal valve in traditional discharging device for coke, not only greatly reduces laid down cost, and simple in structure, failure rate is low, has reduced maintenance workload and expense.
