Description
Technical field
The utility model relates to employed coke dry quenching furnace in the steel industry coking production, refers to a kind of fork-shaped chute of coke dry quenching furnace disposable dust remover particularly.
Background technology
Dry coke quenching is crucial link in the steel industry coke making process, and it has the incomparable advantage of conventional wet quenching at aspects such as improving coke quality, the recycling energy and protection environment.China begins to introduce Dry Quenching Technology from the eighties in 20th century, and this technology is comprehensively applied at present.Dry coke quenching is meant and adopts rare gas element with a kind of method of red burnt cooling refrigerative.Put out in the process dried, red Jiao packs into from the dry coke quenching furnace roof, the low temperature rare gas element is blasted by recirculation blower and absorbs red burnt sensible heat in the coke dry quenching furnace, cooled coke is discharged from the coke dry quenching furnace bottom, carry out heat exchange from the high temperature inert gas that coke dry quenching furnace annular flue comes out to coke dry quenching boiler, boiler produces steam, and cooled rare gas element blasts coke dry quenching furnace again by recirculation blower, and rare gas element uses at system's internal recycle of sealing.
The principle of work of coke dry quenching furnace disposable dust remover is a gravitational dust collection, and purpose is the coarse particles coke powder of removing in the recycle gas, prevents the wearing and tearing of recycle gas to system device and pipeline thereof, the protection generator tube.Be about 10～12g/m through recycle gas dustiness behind the one-time dedusting
3
The fork-shaped chute of coke dry quenching furnace disposable dust remover is trapezium-shaped, and the bottom is connected with water cold sleeve.The coke powder temperature is cooled to discharge below 200 ℃ by the temperature of water cold sleeve with coke powder about 900 ℃ in the fork-shaped chute.Under the effect of recirculation blower, recycle gas is flow at high speed in coke dry quenching furnace, drives coke powder high speed rotating in the fork-shaped chute of disposable dust remover, produces very big frictional force.At present, the inner-wall surface of this fork-shaped chute adopts two-layer refractory casting material (and CL-80) to come heat insulating successively, earlier in the thick CL-80 mould material of internal layer spraying 30mm, again in the thick ZCH-010 mould material of skin spraying 70mm.But in actual production, this fork-shaped chute ubiquity inner lining material comes off, burns phenomenon, brings great difficulty for the steady running of coke dry quenching furnace.There are data to show: after coke dry quenching furnace is put two months into operation, the refractory casting material of fork-shaped chute inner-wall spraying begins to come off under the washing away of high temperature and coke powder, fork-shaped chute outside surface local temperature is up to more than 500 ℃, it is outside that steel plate is very fast is burnt, because of this zone is a negative pressuren zone, a large amount of air enter in the dry coke quenching recycle system and the coke powder burning from burning the position, cause fork-shaped chute interior temperature to rise suddenly, form vicious cycle, add the thick steel plate of weldering 20mm and can not resist washing away of coke powder.And fork-shaped chute outside adds the welding steel plate, the internal spray mould material all needs coke dry quenching furnace stopping production decrease temperature and pressure, also can only guarantee the ordinary production about month after the processing.
Summary of the invention
The purpose of this utility model is exactly that the fork-shaped chute that a kind of Stability Analysis of Structures is reliable, can significantly improve the coke dry quenching furnace disposable dust remover of work-ing life, the steady running of assurance dry quenching system will be provided.
For achieving the above object, the fork-shaped chute of the coke dry quenching furnace disposable dust remover that the utility model is designed, comprise fork-shaped chute body, be coated with one deck refractory lining on the inwall of described fork-shaped chute body, built one deck fireclay brick on the surface of described refractory lining by laying bricks or stones.Described refractory lining adopts the aluminosilicate fiberboard liner, and it is the clay brick of QN53 that described fireclay brick adopts model.
Further, the splayed inclined-plane inwall of described fork-shaped chute body is provided with and institute's fireclay brick of building by laying bricks or stones Γ shape stainless steel stay hook one to one, and a side of the fireclay brick of building by laying bricks or stones is processed with and the described Γ shape stainless steel stay hook groove of hook cooperation mutually.Means are built in hook effect combination by Γ shape stainless steel stay hook by laying bricks or stones, fireclay brick can be arranged in securely the refractory lining outside on the fork-shaped chute inner body wall.
Advantage of the present utility model is: designed be coated on the fork-shaped chute inner body wall refractory lining particularly the aluminosilicate fiberboard refractory lining have fabulous heat-proof quality, designed fireclay brick of building by laying bricks or stones in the refractory lining outside possesses very strong wear resisting property and rapid heat cycle performance, both organically are combined into one, act synergistically mutually, efficiency overcomes the defective that conventional fork shaped chute inner liner abrasive resistant poor performance, the coke powder of unable to bearing are washed away, significantly strengthen the structural stability of fork-shaped chute, thereby significantly improve the stability of dry quenching system operation.Simultaneously, the utility model is simple in structure, construction is easy, easy to maintenance, have a great promotional value.Facts have proved that the utility model trial run nothing more than 2 years comes off and disrepair phenomenon, fork-shaped chute surface temperature is the highest to be no more than 100 ℃, satisfies fully and produces needs, estimates more than 4 years its work-ing life.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The fork-shaped chute of the coke dry quenching furnace disposable dust remover shown in the figure comprises fork-shaped chute body 3, is coated with one deck refractory lining 7 on the inwall of fork-shaped chute body 3, and it is the aluminosilicate fiberboard liner of 30mm that refractory lining 7 adopts thickness.Built one deck fireclay brick 5 on the surface of refractory lining 7 by laying bricks or stones, fireclay brick 5 employing thickness are that the model of 65mm is the clay brick of QN53.According to the difference in orientation all around, the interior wall construction of fork-shaped chute body 3 is also different, for vertical walls and herringbone inclined-plane, builds fireclay brick 5 by laying bricks or stones and does not have any problem.And for the splayed inclined-plane of fork-shaped chute body 3, the place that fireclay brick 5 is not taken root, influenced easily by deadweight comes off downwards, therefore on the splayed inclined-plane of fork-shaped chute body 3 inwall, be welded with and the institute fireclay brick of building by laying bricks or stones 5 Γ shape stainless steel stay hook 6 one to one, one side of the fireclay brick of building by laying bricks or stones 5 is processed with and Γ shape stainless steel stay hook 6 groove that cooperates of hook mutually, fireclay brick 5 can be built securely by laying bricks or stones refractory lining 7 outsides on fork-shaped chute body 3 inwalls like this.
Show through field experiment and measuring and calculating: the utility model can greatly improve the production efficiency of coke dry quenching furnace, can make fork-shaped chute life cycle extend to 5 years by 1 year, artificial, the spare part expense of changing the fork-shaped chute are 50,000 yuan, and year saving spare part and maintenance consume about 40,000 yuan.Needed 4 hours to handle fork-shaped chute inner lining material by every month, 1 year 48 hours maintenance time, dry coke quenching is 76 tons of producing steams per hour, 70 yuan of steam per ton, ten thousand yuan of about 48 * 76 * 70=25 of the benefit of annual voluminous steam.By influence dry coke quenching generating 4 hours in every month, dry coke quenching 4000 degree that per hour generate electricity, ten thousand yuan of annual multiple electric about 12 * 4 * 4000=19 of benefit.
