Abstract

An improved, environmentally sound method and cost effective handling and indirect cooling system is provided for coke as it is pushed out of the coke oven (103), indirectly cooled in a coke box (8) and discharged at a receiving station (105). The system uses a coke box (8) having approximately the same internal size and shape of the coke oven (103). The box (8) which is effectively sealed at the coke oven (103) during the push is covered by flowing water during the push and during the cooling cycle. A carrier (100) moves the box (8) to a cooling rack (104) and places the box (8) into the rack. The carrier (100) then moves to an adjacent cooled box (8), removes it from the cooling rack (104), transports the box (8) to an environmentally sound receiving station (105) and discharges the coke from the box (8) in substantially its original 'cake' form into the receiving station. When space is not available near existing ovens for cooling racks (104), the hot coke can be pushed from the box into the receiving station and dumped or the hot coke may be pushed into a receiving chute (58) or directly onto a wharf (109) or pit and wet quenched with water. The method and apparatus of the invention are environmentally friendly, improve the quality of the coke, improve the yield of each push, and increase the size of the coke which is also an advantage. The coke cooling and handling method and apparatus also have the potential to reduce the time the coke needs to spend in the oven thereby increasing the productivity of the ovens. There is also a potential of treating the coke as it is cooled in the box (8) to further improve the quality of the coke.

Description

The method and apparatus of processing and indirectly cooling coke

FIELD OF THE INVENTION

The present invention relates generally to a system that handles coke with mode favourable on the environment, it can eliminate the discharging between promotion and cold snap basically, especially relate to a coke box and carrier, it receives hot coke from stove, coke is transported to an indirect cooling station and when cooling off, with mode favourable on the cost coke briquette is transported to the receiving station of an environmentally safe, and discharges coke at this station.

The background of invention

In traditional pit kiln, coal is heated to about 2000 °F. and about 20～40 hours, to discharge all volatilization gas and other material, they accounted for about 30% of coal weight.Then will be still heat and from stove, release at the incendiary coke, making it quenching cools off, and is placed on the load/unload stations, to transport with suitable transportation equipment.In the process of promotion and quenching, unsteered discharging is very deleterious and very disadvantageous to environment, and should eliminate as much as possible.It is also recognized that traditionally promotion emission control and quenching emission control all are systems independently, and can have one and do not have another.In fact, because the life-span of pit kiln and the great expense of this facility still do not have the coml dry quenching system that has effective environment control at north America region.In Europe, most of pit kiln need have all new stove STRENGTH ON COKE of dry quenching system and worldwide consideration must utilize dry quenching.

In the typical coking system of aforesaid North America institute type of service, the coke of heat is transported on the rail vehicle or other suitable carrier of a wet quenching station by the coke of releasing from stove and dropping to heat.To understand particularly dropping of hot coke, also produce further burning, extinguished by quenching up to coke with producing a large amount of particulate matter and coke.Wet quenching uses thousands of gallons water, and most of water is converted into steam and disappears in atmosphere immediately.Steam takes up many chemical substances of being harmful to environment and they is discharged in the atmosphere.

One substitute mode of wet quenching is dry quenching and recently has been used and/or is essential in some country.In dry quenching, a rail vehicle loads a box, and it collects the coke that falls from stove.Accommodate heat and still the box of incendiary coke be brought to a high silo place then, be thus lifted to the top of silo and again coke fallen, be to fall in the silo at this moment.Then by in silo, carrying rare gas element to come cooling coke through coke.Heat from rare gas element is recovered and is used as other purpose in some cases.But the value of the heat of recovery seldom can be repaid the high fund cost and the operation overhead of this dry quenching system.

Another major defect of this dry quenching system can be worn and torn during to the bottom dropped out of silo from the top of silo by deadweight when coke itself.This can reduce the output of useful coke.Must be the form of bulk for steel-making and the useful coke of foundary industry.Seldom valuable by the physical operations of coke in process of cooling with small-particle or coke " slag " that decomposition is produced.

In all above-mentioned situations, suppress to drop and move to the cost of another local time produced pollution from a place very high when coke.In the past, the pushing emission control system that has proposed many types suppresses this pollution.But, still have a large amount of this systems to be substituted, because they can not satisfy the environmental requirement of increasingly stringent.Really, the many systems in usefulness do not satisfy environmental standard at present, but still allow its operation, will have serious negative commercial impact of a potential because close them.In addition,, unnecessarily reduced, therefore need have been replaced with more favourable on the environment and reliable standard in suitable local environment standard because the getable technology of institute is limited at present.In addition, in fact the installation of all existing systems and operation are all very expensive.

The pit kiln that it is also recognized that commercial operation must have coke is transported to another local backup device from a place, even their environmental control system is inoperative or just repaired.This is because stove itself must be operated constantly, controls even without the environment that suitably moves and handles and cooling coke.This also is negative influence to environment certainly.

The general introduction and the purpose of invention

The improved method and apparatus of treatment in accordance with the present invention and indirectly cooling coke has been eliminated the existing all problems of other system basically, and its method only is such problem that do not produce at the very start.But, hot coke never is exposed to atmosphere, never is subjected to physical interference, and primary " bulk " form when always keeping as it in stove, even its be dried the cooling and be placed on the coke load/unload stations then after, still keep its primary " bulk " form.Be understandable that coke disposal of the present invention and indirect cooling system will have a substantial gain on investments, and other system needs very big fund, does not have the refundment ability, has very high running cost, and does not have desirable reliability.In addition, traditional system is because it is tending towards reducing output, although therefore legacy system can bring income, also will continue to reduce it and use, but and system of the present invention desired display goes out very positive economical effectiveness.

Improved environmentally safe of the present invention with cost on effectively coke disposal and indirect cooling system use a coke box, this coke box has an inside of the size and shape that is roughly pit kiln.This box that is sealed to effectively in pushing course on the pit kiln is preferably covered by mobile water in the process of promotion and refrigeration cycle.One carrier moves to box on one cooling frame and with box and is placed in the shelf.Carrier is shifted to an adjacent chilled box then, and it is removed from cooling frame, box is transported to the receiving station of an environmentally safe and coke is discharged on the receiving station from box.Method and apparatus of the present invention is favourable on environment, can improve the quality of coke, improves the output of each promotion and increases the size of coke, and this also is an advantage.The present invention also has the potentiality that reduce coke spent time in stove, thereby increases the output of pit kiln.In addition, also has the potential possibility of when at the box internal cooling, handling coke, with the further quality of improving coke.

It is also recognized that many existing stoves are in the zone of unusual limitation and are not used in the space of a cooling frame of preferred type, essential use wet quenching in these situations.The present invention is a huge improvement for existing promotion blowdown system, and wherein existing systems may need big bagroom, big vacuum fan, big gas exhaust duct and be used for the special service valve of each stove.All very expensive and their the own generation pollutions of the construction of all these systems and maintenance.In addition, when promoting, these systems are effective on environment like that not as system of the present invention.In addition, more reliable at this disclosed vote.For example, system of the present invention is not a fixed system.It provides extra carrier and coke box to carry out the off-line repair and maintenance, and fixed system does not then have, and makes can not operate when the needs repair and maintenance.System of the present invention also produces higher output, because the coke of heat is not abandon.On the contrary, it will be to slide, and this just greatly touches on the receiving surface and reduces the discharging of particulate matter thus widely.In order further to reduce these dischargings, can increase by one and receive chute.In addition, even the coke loss that is caused by burning is when the needs wet quenching, with the sub-fraction that is the loss that had with traditional promotion blowdown system.

Even under impossible those situations of dry cooling slowly, and wet quenching is when becoming unique selection, coke that also can " lentamente " wet quenching heat.On the contrary, use the quenching of heating of a traditional quench tower only to finish in 1 or 2 minute, because keep the quenching car of hot coke must continue circulation and turn back to pit kiln apace.As a result, may suppress steam and corresponding pollutent by thousands of gallons the enormous amount that water produced hardly, wherein these water are to be used for the hot coke of quenching apace.But, coke box of the application of the invention and carrier are transported to hot coke a receiving station that has two load/unload stations, wherein each side at receiving box has a load/unload stations, can obtain the hot coke of " lentamente " wet quenching and reach 20 minutes, and still keep 10 minutes promotion cycle from stove.Like this, provide " slowly " wet quenching hot coke, will suppress a very high per-cent of traditional quenching pollutant, even dry slowly indirectly when cooling is not optional object when what have all attendant advantages of the present invention up to 10 minutes.

By the following description that the reference accompanying drawing is read a preferred embodiment of the present invention, these and other feature of the present invention and advantage will be more apparent.

Detailed description of preferred embodiment

Now more specifically with reference to accompanying drawing, the present invention includes a carrier 100, it comprises a body frame structure 1 that is bearing on the rail wheel 2, and described rail wheel 2 rolls on ground rail 3, before wherein ground rail 3 accurately is arranged on a coke oven battery 103.Track 3 also is used for the coke box 8 on the carrier 100 is moved and navigate to one of pit kiln 103, a cooling frame 104 and a receiving station 105 fronts.Ground rail 3 keeps carriers 100 from the suitable height and distance of stove 103.The horizontal position of carrier 100 is by the control of other suitable device, with along the mobile selectively carrier of track 3.Those of ordinary skill in the art should be understood that coke is pushed in the box 8 from stove before, in Fig. 1 by 18 illustrate the face of land to show a mechanism be used for taking off door and the door that after pushing, closes again from pit kiln 103.No matter the present invention is the door mechanism 18 that adopts or do not adopt as an integral part of carrier 100, all can work.

As what Figure 4 and 5 illustrated best, body frame structure 1 is loaded a big water tank 5, the vertical tube 6 that this water tank has a pump and leads to the top of the skeleton construction 1 on box 8.Pipe 6 is connected on the horizontal pipe 7, and this horizontal pipe is dispensing water on the top of the coke box 8 of heat, and water is run down on the box 8, the coke inside of cooling box and heat.Water is expelled back in the chest 5 and is recycled then.

Coke box 8 has two doors.In the front of box 8 are dropping doors 10, and are a swing door 11 in the back.When closing, two

doors

10 and 11 all closely are sealed on the respective front ends and rear end of box 8.Door 11 at box 8 rear portions preferably has a unidirectional outlet 12, is discharged and is lighted by the still releasable volatile gases of coke in the time of its permission some cycles after promotion.Be to be understood that the perfect combustion basically of the gas lighted, thereby environmental sound.In addition, because not discharging meeting effusion in pushing course, and in box, can proceed some coking, therefore can utilize the output that reduces to increase stove of the time of coke in stove.

Dropping door 10 in box 8 fronts is opened and closed by the actuator arm 38 that is connected on the body frame 1, and by cylinder 39 controls.Dropping door 10 preferably includes locating slot 49, and when box 8 moves to the position of post 36 by oven door jamb 22 or receiving box, door actuating arm 38 will guide whereabouts gate slot 49 with the suitable locator protrusions on corresponding door jamb.Can open and close door 10 then as required.In the time of in coke box 8 is withdrawn into body frame 1, actuator arm 38 is by the enough degree of revolution, to avoid a mechanism 18 when travelling on the track 3 of carrier before stove 103.

As shown in Figure 3A, coke box 8 preferably has 4 groups of rail wheels.Outer group 13 and interior group 14 both allow box 8 to drive front and back free movement on the pair of tracks 4 carrier framework 1 under the effect of cylinder 15 (referring to Fig. 2 A) being arranged at one under the box 8.As previously mentioned, wish that carrier 100 can cross the door mechanism 18 on microscler 19 that is positioned at before the stove 103.So at least six feet places must push back box 8 on distance stove 103 surfaces.

When " an imperial tongue " 20 that constitutes by object 16,17,24,25,26,40 and 41 during selectively to arbitrary the advancing of the stove shown in Fig. 1 103, cooling frame 104 or receiving station 105, perhaps when the reception chute 58 of the modification shown in Figure 10 advances, group wheel 13 is arranged on outside the supporting member of body frame case track 4 outside preceding on box 8.But " imperial tongue " 20 is not a vertical load that is designed to support the shell ground operation that passes in and out carrier 100.Therefore, interior group of wheel 14 needs supporting box 8.

Drive cylinder 15 and preferably be connected on the drives structure 17, this structure comprises a lock-up cylinder 40 and the locking box lock 16 to the box 8.When box lock 16 is on the throne, actuator 15 control boxes 8 seesawing with respect to body frame 1.Receiving and discharging in the process of coke, when box lock 16 was on the throne, " imperial tongue " 20 also was used for transmitting horizontal forces to driving cylinder 15.

Should be appreciated that the position that when box lock 16 is on the throne, has three basic boxes 8.The first, when driving cylinder l5 withdrew fully, box 8 was drawn in the carrier 100.When carrier 100 motions, use this position and allow box 8 and carrier 100 freely to cross a mechanism 18.Second position makes box 8 and its corresponding box sealing member abut to tightly on the oven door jamb 22, is in the position of reception from the coke of stove 103 releases.When box 8 abuts on the other post 36 of receiving station, also use this position.When upholding fully, cylinder 15 produces the 3rd position when driving.This is positioned at box 8 on the cooling frame 104, and a lifting cylinder 25 overcomes a cooling frame reaction plate 55 and upholds herein, thereby forces a head roll 24 to abut on the box 8.Separate then and unblank 16, and a CD-ROM drive motor 26 and cylinder 24 drive forwards box 8 and enter in the support 104.When the box 8 that is cooled was in support 104 is withdrawn into carrier 100, operating process was opposite.In order to support " imperial tongue " 20, and unexpectedly support the weight of box 8, two series cylinders 35 be arranged on body frame 1 the end and with " imperial tongue " 20 on the opposite side engagement of a supporting track 41.On cooling frame 104, be provided with supporting track 37.

When receiving station, two

doors

10 and 11 all open and the refrigerative coke can be released from either direction by a push rod 28.The parts of push rod 28 or the carrier 100 shown in Fig. 1,3～5 and 8～10, or shown in Fig. 6,7 and 11 independently and be positioned at the parts of the arbitrary end of carrier.In a preferred embodiment, push rod 28 rear portion and the coke that are connected to carrier 100 can be released easily in any position.Be to be understood that if push rod 28 is fixed on the carrier 100 rigidly, the length of carrier 100 and operation carrier required area difference seldom increased be twice.According to the present invention, by body frame 1 rotating push-rod 28 and push rod drives structure 2990 degree or bigger with respect to carrier 100, can cancel this overwork space, wherein push rod drives structure 29 comprises push rod idler pulley 48, a push rod CD-ROM drive motor 51, tooth bar 52, pinion(gear) 53 and 90 degree drive pinions 54, and carrier 1 then has a ram drive structure rotating cylinder 42.

Further according to the present invention, when push rod drives structure 29 was rotated, it preferably opened the hermatic door 11 on the box behind.This is to finish by two push arms 30 that are installed in rotationally on the push rod drives structure 29.Push arm 30 and then contact and promotion are installed in two spring-loaded arms 31 on the box that loads back door 11.When push rod drives structure 29 is rotated, just overcome the spring 33 that door is closed tightly.Two spring-loaded arms 31 remain on two door central authorities with door 11 and install on the bearing 32, and one of them is at the top, and another is in the bottom, and when door was closed the rear portion of box 8, these bearings applied power equably to door 11.Certainly can understand, transformable is that door 11 also available independent device are opened, and when independently push rod 28 being installed shown in Fig. 6,7 and 11, will provide this independent device.

At receiving station 105,, open Qianmen 10 as mentioned above along with from stove 103, releasing coke.Then when push rod 28 is positioned at position shown in Fig. 4, can promote heat or the refrigerative coke briquette enter in the receiving box 34.Push rod 28 is withdrawn and turn-off as shown in Figure 5 then, and spring 33 is closed door 11.When carrier 100 during to 103 operations of next stove, Qianmen 10 can stay open, to receive the initiate hot coke of releasing from stove.

After receiving the refrigerative coke, rotate load/unload stations receiving box 34, and still for the cooling coke 27 of " bulk " form just skids off on the coke load/unload stations 43, and will keep its bulk form effectively.This process has an additional advantage.Analyze cooling coke 27 with suitable optics or other test set then, this can show how each stove 103 and each zone of cooling frame 104 operate.When promoting, receiving box 34 can be turned to opposite side next time, with the ability that provides additional cargo handling productivity and the coke that the opposite side with corresponding stove 103 and cooling frame 104 is contacted to analyze.In the example shown, load/unload stations receiving box 34 usefulness cylinders 45 are installed in the front portion, its intermediate roll 45 usefulness one roller frame shelf structure 46 supportings.Rearward, its bearing 47 of installing with central authorities supports, and described bearing 47 bears vertical and horizontal power.Preferably, load/unload stations receiving box 34 can rotate 120 degree or more in each direction by two inclined cylinders 44 that are installed on the load/unload stations 43, perhaps also can rotate with other power-actuated wheelwork.

In the situation with the particular surroundings that can benefit from this layout, being independent of coke box carrier 100 installations one push rod 28 also is the intent of the present invention.A kind of interchangeable layout like this is illustrated in Fig. 6 and 7, wherein push rod 28 is installed in by independently on transport establishment or the carrier 107 of track meshing wheel 110 supporting, described track meshing wheel is ridden and is leaned against on the pair of tracks 106 that is parallel to track 3 settings, and its middle orbit 3 supporting coke close carrier 100.And, having coke when must be discharged on the load/unload stations 109, this load/unload stations 109 will allow to be picked up coke and be placed into it on haulage truck rather than be placed on the other conveying belt of load/unload stations by a shovel loader.This wants and can not be undertaken by a push rod 28 that is installed on the carrier 100, and can not be undertaken by the push rod that is installed in independently on the transfer mechanism 107, and wherein transfer mechanism is independently travelling on the track 106.Fig. 6 is illustrated in the position of releasing push rod 28 before the coke from box, and Fig. 7 represents to stretch into basically in the coke box coke is released the push rod 28 on the load/unload stations 109.

Also may need or wish in some cases to replenish or even replace the indirect cooling of STRENGTH ON COKE in cooling frame 104 with the lip-deep coke of wet quenching coke load/unload stations 43.For this reason, can go into to be provided with a plurality of water jets 50 at the concave surface of load/unload stations 8 as shown in Figure 8, upwards to penetrate coke " piece " 27 ground shower cooling water as shown in Figure 9.In addition, also as shown here, the upper surface of coke " piece " also can be with a plurality of water jet 52 shower cooling water, and wherein water jet 52 is supplied with water by the pipe or the manifold 51 that are installed on the load/unload stations 43.

Because the physical layout of coking facility and other space constraint may be wished to discharge coke " piece " 57 from coke box 8, and coke " piece " 57 be converted to the orientation of an approximate horizontal from the position of its approximate vertical.As shown in Figure 10, the present invention realizes such discharge by a transition chute 58 that is fixed on the coke box 8, thereby receive the coke " piece " 57 released by push rod 28 and will about 90 degree of " piece " 57 conversions, thereby its approximate horizontal ground is from outlet end 56 discharges of chute 58.It will be appreciated that such discharge chute 58 can be used for readjusting coke " piece " in cooling frame 104 after coke " piece " is cooled, perhaps interchangeablely be, coke can come wet quenching by the suitable water jet 54 that is installed on the transfer manifold on the coke " piece " 57, and wherein coke " piece " 57 is positioned on the opening slipper 56 of discharging chute 58.

By an aforementioned novel method and the device that is used to handle with indirectly cooling coke that provide as can be seen, it can reach aforesaid purpose.When needing, can use wet quenching to replenish or replace indirect cooling frame owing to the consideration on the space.Except specifically illustrating herein and describing, various other modifications of embodiment are conspicuous for the person of ordinary skill of the art, especially when according to instruction of the present invention.The present invention should not be construed as limited to shown here go out and describe have an embodiment, but also should comprise such substitute mode.
