Description

Technical Field

[0001] This application relates to the field of dry quenching technology, and more specifically, to a fully dry quenching system. Background Technology

[0002] Currently, most independent coking plants use tamping coke ovens. In the early stages of plant construction, environmental regulations were relatively lenient, and wet quenching was employed. However, with the introduction of environmental regulations and increased energy management requirements, the advantages of dry quenching in terms of pollutant emissions, energy recovery, and coke quality have gradually become apparent. Coking plants using wet quenching have already completed their first round of technological upgrades, adding a dry quenching oven to their existing wet quenching units. The wet quenching unit is used during the annual inspection of the dry quenching oven. The layout of this scheme is as follows: Figure 1 As shown, a wet quenching device 2 is located at one end of the tamping coke oven 1, and a dry quenching coke oven 3 is arranged at the other end of the coke oven. The coke car runs back and forth between the tamping coke oven 1, the wet quenching device 2 and the dry quenching coke oven 3 to complete the quenching task.

[0003] With advancements in advanced coking technology and increasingly stringent environmental regulations, some provinces have mandated that newly built coke ovens adopt a fully dry quenching process, and required existing coking enterprises to complete their dry quenching upgrades within a specified timeframe. For coking enterprises that have already completed the first round of dry quenching upgrades, this means abandoning their existing wet quenching methods and installing a new dry quenching coke oven along with supporting auxiliary and coke processing equipment, interconnecting it with their existing systems. Compared to the first round of upgrades, the challenges in terms of coke transportation methods, existing site layout, construction period, and system operational stability have significantly increased.

[0004] The choice between top-charging and stamped coke ovens requires comprehensive consideration of various factors, including investment and operating costs, market demand, and the company's own development plans. Due to changes in coking technology, customer needs, and coal blending costs, some independent coking enterprises using stamped coke ovens are seeking transformation and upgrading, maintaining stable production with their existing stamped coke ovens while constructing a new set of top-charging coke ovens to produce top-charged coke and expand into the top-charged coke market.

[0005] Using two sets of coke ovens, one top-loading and one tamping coke oven, in the same site and achieving complete dry quenching of coke will face problems such as narrow site, high investment and complex coke transportation system. For upgrade and renovation projects, the transformation is difficult and the original production system will face a long period of shutdown, affecting the service life of the original coke ovens.

[0006] To achieve complete dry quenching, two sets of coke ovens typically employ two layout configurations: a collinear arrangement and a parallel arrangement. However, due to site constraints, the two sets of coke ovens cannot use the conventional collinear arrangement and must instead use the parallel arrangement. Figure 2As shown, the tamping coke oven group 11 and the top-loading coke oven group 12 are each two independent coke oven systems. Each coke oven system contains two dry quenching coke ovens 3. This arrangement is suitable for plots with limited coke oven space. The dry quenching systems are used independently, eliminating the need for switching between top-loading and tamping dry quenching systems. However, this arrangement has high investment costs, and the two dry quenching coke ovens 3 serve as backups for each other, resulting in low operating loads, both below 50%.

[0007] Therefore, how to reduce equipment investment and improve the utilization efficiency of dry quenching coke ovens has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the purpose of this application is to provide a fully dry quenching coke treatment system to reduce equipment investment and improve the utilization efficiency of dry quenching coke ovens.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] A fully dry quenching coke treatment system includes a coke oven group and a dry quenching coke oven. The coke oven group includes a first coke oven group and a second coke oven group. A first quenching car track is provided on one side of the first coke oven group, and a second quenching car track is provided on one side of the second coke oven group. The first quenching car track and the second quenching car track are arranged in parallel and both are equipped with coke tank transport vehicles.

[0011] The dry quenching coke oven includes a first dry quenching coke oven, a second dry quenching coke oven and a third dry quenching coke oven. The first dry quenching coke oven is located at one end of the first quenching car track. The second dry quenching coke oven and the third dry quenching coke oven are arranged in a co-line manner and are located at one end of the second quenching car track.

[0012] A first hoist derrick is installed between the first dry quenching coke oven and the first quenching car track; a second hoist derrick is installed between the second dry quenching coke oven and the second quenching car track; and a third hoist derrick is installed between the third dry quenching coke oven and the first quenching car track. The third hoist derrick spans the first and second quenching car tracks. Hoists are installed on the first, second, and third hoist derricks.

[0013] The first dry quenching coke oven is equipped with a first conveyor belt group, and the second and third dry quenching coke ovens are equipped with a second conveyor belt group. At least one of the two conveyor belts in the first belt unit of the second conveyor belt group can run in reverse, and the conveyor belt that can run in reverse is connected to the first conveyor belt group.

[0014] Optionally, in the above-mentioned dry quenching system, the first coke oven group is a tamping coke oven group, and the second coke oven group is a top-loading coke oven group.

[0015] Optionally, in the above-mentioned dry quenching system, the first and second conveyor belt groups are connected by a third conveyor belt group.

[0016] Optionally, in the above-mentioned dry quenching system, the second conveyor belt group includes several conveyor belt units, and each conveyor belt unit includes two conveyor belts.

[0017] Optionally, in the above-mentioned dry quenching system, a first transfer station is provided between the first belt unit and the third conveyor belt group, and the conveyor belt that can run in reverse is connected to the first transfer station.

[0018] Optionally, in the above-mentioned dry quenching system, the first transfer station is equipped with a chute and a dust removal assembly, with the chute located between the first belt unit and the third conveyor belt group.

[0019] Optionally, in the above-mentioned dry quenching system, a second transfer station and a third transfer station are provided between the third conveyor belt group and the first conveyor belt group, and a fourth transfer station is provided between two adjacent conveyor belt units of the second conveyor belt group.

[0020] Dust removal components are installed at the second, third, and fourth transfer stations.

[0021] Optionally, in the above-mentioned dry quenching system, both conveyor belts in the first belt unit can run in reverse, and both conveyor belts are connected to the first transfer station.

[0022] Optionally, in the above-described dry quenching system, the first conveyor belt group includes one or two conveyor belts; and / or,

[0023] The third conveyor belt group consists of one or two conveyor belts.

[0024] Optionally, in the above-mentioned dry quenching system, the first conveyor belt group, the second conveyor belt group, and the third conveyor belt group are all equipped with sealed corridors.

[0025] As can be seen from the above scheme, the fully dry quenching coke processing system disclosed in this application has three dry quenching coke ovens in the first and second coke oven groups, which share a third dry quenching coke oven. Compared with the scheme of setting four dry quenching coke ovens, this reduces the number of dry quenching coke ovens to be built, reduces equipment investment, and saves construction costs. The three dry quenching coke ovens serve as backups for each other, which, compared with the scheme of setting four dry quenching coke ovens, can fully utilize the processing capacity of each dry quenching coke oven and improve the utilization efficiency of the dry quenching coke ovens. This system can be used for dry quenching coke from the same type of coke oven group, and the setting of the first conveyor belt group and the second conveyor belt group can be used as backups for each other to ensure the stable operation of the system. This system can also be used for dry quenching coke from different types of coke oven groups, ensuring that different types of coke enter their respective processing units and that coke is not mixed during the production process. This system can be used for new coking projects as well as for upgrading and transforming coking projects. Attached Figure Description

Detailed Implementation

[0046] Explanation of related terms:

[0047] Top-charged coke ovens and tamped coke ovens: These are two types of coke ovens with different coal charging methods and different coal blending schemes, resulting in differences in the quality of the produced coke. Top-charged coke ovens are mostly found in integrated iron and steel enterprises, where coal blending costs are higher, and the produced coke is suitable for large blast furnaces.

[0048] Wet quenching: Water is sprayed over hot coke to cool the coke and extinguish the flame using steam.

[0049] Dry quenching: Inert circulating gas is used to cool high-temperature coke, recover the sensible heat of the red coke, and release the heat in the boiler to produce high-temperature and high-pressure steam for power generation.

[0050] Dry quenching: Multiple dry quenching ovens are set up. During normal production, all dry quenching ovens are in use. When one dry quenching oven is under maintenance or in an accident, the remaining dry quenching ovens can meet the normal production operation of the coke oven.

[0051] The core of this application is to disclose a fully dry quenching coke oven system to reduce equipment investment and improve the utilization efficiency of dry quenching coke ovens.

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] like Figure 3 As shown in the figure, this application discloses a fully dry quenching coke treatment system, including a coke oven group and a dry quenching coke oven 3.

[0054] The coke oven group includes a first coke oven group 11 and a second coke oven group 12. The first coke oven group 11 includes two stamping coke ovens or two top-loading coke ovens, and the second coke oven group 12 includes two stamping coke ovens or two top-loading coke ovens. A first quenching car track 21 is provided on one side of the first coke oven group 11, and a second quenching car track 22 is provided on one side of the second coke oven group 12. The first quenching car track 21 and the second quenching car track 22 are arranged in parallel and are both equipped with coke tank transport cars. The coke tank transport cars are used to transport the red coke produced by the coke oven group to the corresponding dry quenching coke oven 3, and the dry quenching coke oven 3 performs dry quenching treatment on the red coke.

[0055] The dry quenching oven 3 includes a first dry quenching oven 31, a second dry quenching oven 32, and a third dry quenching oven 33. The first dry quenching oven 31 is located at one end of the first quenching car track 21 and performs dry quenching treatment on the red-hot coke produced by the first coke oven group 11. The second dry quenching oven 32 and the third dry quenching oven 33 are arranged in a collinear manner and located at the same end of the second quenching car track 22. The second dry quenching oven 32 and the third dry quenching oven 33 perform dry quenching treatment on the red-hot coke produced by the second coke oven group 12.

[0056] A first hoist derrick is installed between the first dry quenching oven 31 and the first quenching car track 21. A second hoist derrick 41 is installed between the second dry quenching oven 32 and the second quenching car track 22. A third hoist derrick 42 is installed between the third dry quenching oven 33 and the first quenching car track 21. The third hoist derrick 42 spans the first quenching car track 21 and the second quenching car track 22. Hoists are installed on the first hoist derrick, the second hoist derrick 41, and the third hoist derrick 42. The hoists can lift the coke cans on the coke can transport cars and transport them to the top of the corresponding dry quenching oven 3. The opening mechanism opens the valve on the coke can, and the red coke falls into the dry quenching oven 3. Then, the empty coke can is transported to the coke can transport car, and the coke can transport car returns to the coke oven group to continue the above operation.

[0057] The first dry quenching coke oven 31 is equipped with a first conveyor belt group 51 capable of transporting the dry quenched coke produced by the first coke oven group 11 to the coke processing device. The second dry quenching coke oven 32 and the third dry quenching coke oven 33 are equipped with second conveyor belt groups 52 capable of transporting the dry quenched coke produced by the second coke oven group 12 to the coke processing device. The first belt unit 521 of the second conveyor belt group 52 includes two conveyor belts, at least one of which is reversible and connected to the first conveyor belt group 51. Figure 11 As shown, for ease of explanation, the first belt unit 521 includes a first transport belt 521A and a second transport belt 521B, and the second transport belt 521B is defined to be reversible.

[0058] like Figure 11 As shown, when the first dry quenching coke oven 31, the second dry quenching coke oven 32, and the third dry quenching coke oven 33 are operating simultaneously, the red coke produced by the first coke oven group 11 enters the first dry quenching coke oven 31 for dry quenching treatment. The dry quenched coke produced after dry quenching is transported to the corresponding coke processing device via the first conveyor belt group 51. The red coke produced by the second coke oven group 12 enters the second dry quenching coke oven 32 and the third dry quenching coke oven 33 for dry quenching treatment. The dry quenched coke produced after dry quenching is transported to the corresponding coke processing device via the second conveyor belt group 52. At this time, one or both of the first conveyor belt 521A and the second conveyor belt 521B can be operated simultaneously, preferably one of them, with the other as a backup. If the first coke oven group 11 and the second coke oven group 12 are of the same type, the dry-quenched coke produced by the second dry-quenching coke oven 32 and the third dry-quenching coke oven 33 can be discharged onto the second conveyor belt 521B. The transport direction of the second conveyor belt 521B can be changed, and the second conveyor belt 521B runs to the left and is transported to the coke processing device via the first conveyor belt group 51. Except for the operation of the second conveyor belt 521B, the second conveyor belt group 52 does not operate and is used as a standby.

[0059] like Figure 3 and Figure 12 As shown, when the first dry quenching coke oven 31 is under maintenance, the red-hot coke produced by the first coke oven group 11 is transported by a coke can carrier to the area below the third hoist derrick 42. The hoist lifts the coke can and transports it to the area above the third dry quenching coke oven 33. The opening mechanism then opens the valve at the bottom of the coke can, allowing the red-hot coke to fall into the third dry quenching coke oven 33 for dry quenching. The red-hot coke produced by the second coke oven group 12 enters the second dry quenching coke oven 32 for dry quenching. The dry-quenched coke produced by the second dry quenching coke oven 32 is transported to the corresponding coke processing device via the second conveyor belt group 52. If the first coke oven group 11 and the second coke oven group 12 are of the same type, the transport direction of the second conveyor belt 521B can be changed. The second conveyor belt 521B runs to the left, and the dry-quenched coke produced by the second dry quenching coke oven 32 is discharged onto the second conveyor belt 521B and transported to the coke processing device via the first conveyor belt group 51. Except for the operation of the second conveyor belt 521B, the second conveyor belt group 52 is not in operation and serves as a standby.

[0060] like Figure 11 As shown, when one of the second dry quenching coke oven 32 and the third dry quenching coke oven 33 is under maintenance, the red-hot coke produced by the first coke oven group 11 enters the first dry quenching coke oven 31 for dry quenching treatment, and the resulting dry-quenched coke is transported to the corresponding coke processing device via the first conveyor belt group 51; the red-hot coke produced by the second coke oven group 12 enters the one of the two dry quenching coke ovens 32 and the third dry quenching coke oven 33 that is not under maintenance for dry quenching treatment, and the dry-quenched coke is transported to the corresponding coke processing device via the second conveyor belt group 52. At this time, only one of the first conveyor belt 521A and the second conveyor belt 521B can be operated, and the operating direction is to the right. If the first coke oven group 11 and the second coke oven group 12 are of the same type, the transport direction of the second conveyor belt 521B can be changed. The second conveyor belt 521B runs to the left. The dry-quenched coke produced by the one that has not been repaired between the second dry quenching coke oven 32 and the third dry quenching coke oven 33 is discharged onto the second conveyor belt 521B and transported to the coke processing device via the first conveyor belt group 51. Except for the operation of the second conveyor belt 521B, the second conveyor belt group 52 does not operate and serves as a backup, which can ensure the stable operation of the system.

[0061] The fully dry quenching coke processing system disclosed in this application embodiment has three dry quenching coke ovens 3 in total, with the first coke oven group 11 and the second coke oven group 12 sharing a third dry quenching coke oven 33. Compared with the scheme of setting four dry quenching coke ovens 3, it can reduce the number of dry quenching coke ovens 3 to be built, reduce equipment investment, and save construction costs. The three dry quenching coke ovens 3 serve as backups for each other. Compared with the scheme of setting four dry quenching coke ovens 3, it can fully utilize the processing capacity of each dry quenching coke oven 3 and improve the utilization efficiency of the dry quenching coke ovens 3. The system can be used for dry quenching coke of the same type of coke oven group. The setting of the first conveyor belt group 51 and the second conveyor belt group 52 can serve as backups for each other to ensure the stable operation of the system. The system can also be used for dry quenching coke of different types of coke oven groups to ensure that different cokes enter their respective processing devices and that coke is not mixed during the production process. The system can be used for new coking projects or for upgrading and transforming coking projects.

[0062] Furthermore, in some specific embodiments, the first coke oven group 11 is a tamping coke oven group, the second coke oven group 12 is a top-loading coke oven group, the first conveyor belt group 51 transports the dry-quenched coke (hereinafter referred to as tamping coke) produced by the first dry-quenching coke oven 31 to the tamping coke processing device, and the second conveyor belt group 52 transports the dry-quenched coke (hereinafter referred to as top-loading coke) produced by the second dry-quenching coke oven 32 or the third dry-quenching coke oven 33 to the top-loading coke processing device.

[0063] like Figure 11 As shown, when the first dry quenching coke oven 31, the second dry quenching coke oven 32, and the third dry quenching coke oven 33 are running simultaneously, the red coke produced by the first coke oven group 11 enters the first dry quenching coke oven 31 for dry quenching treatment. The compacted coke produced after dry quenching is transported to the compacted coke processing device via the first conveyor belt group 51. The red coke produced by the second coke oven group 12 enters the second dry quenching coke oven 32 and the third dry quenching coke oven 33 for dry quenching treatment. The top-loaded coke produced after dry quenching is transported to the top-loaded coke processing device via the second conveyor belt group 52. At this time, one of the first conveyor belt 521A and the second conveyor belt 521B can be operated, with the other one as a backup.

[0064] like Figure 3 and Figure 12As shown, when the first dry quenching oven 31 is under maintenance, the red-hot coke produced by the first coke oven group 11 is transported by a coke can carrier to the area below the third hoist derrick 42. The hoist lifts the coke can and transports it to the area above the third dry quenching oven 33. The opening mechanism then opens the valve at the bottom of the coke can, allowing the red-hot coke to fall into the third dry quenching oven 33 for dry quenching. The compacted coke produced by the third dry quenching oven 33 is discharged onto the second conveyor belt 521B. At this time, the running direction of the second conveyor belt 521B is changed, and the second conveyor belt 521B runs to the left, conveying the compacted coke onto the first conveyor belt group 51, and then to the compacted coke processing device. The red-hot coke produced by the second coke oven group 12 enters the second dry quenching oven 32 for dry quenching. The top-loaded coke produced by the second dry quenching oven 32 is discharged onto the first conveyor belt 521A, and the first conveyor belt 521A runs to the right, transporting the top-loaded coke to the top-loaded coke processing device. The second conveyor belt 521B operates simultaneously with the first conveyor belt 521A, but in opposite directions.

[0065] like Figure 11 As shown, when one of the second dry quenching oven 32 and the third dry quenching oven 33 is under maintenance, the red-hot coke produced by the first coke oven group 11 enters the first dry quenching oven 31 for dry quenching treatment, and the resulting compacted coke is transported to the compacted coke processing device via the first conveyor belt group 51. The red-hot coke produced by the second coke oven group 12 enters the one of the two dry quenching ovens 32 and 33 that is not under maintenance for dry quenching treatment, and the top-loaded coke after dry quenching is transported to the top-loaded coke processing device via the second conveyor belt group 52. At this time, only one of the first conveyor belt 521A and the second conveyor belt 521B can be operated, with the other as a spare, and the operating direction is to the right. This system can simultaneously meet the smooth discharge of two types of coke, ensuring that different cokes enter their respective processing devices and that coke is not mixed during the production process.

[0066] Furthermore, when the first dry quenching coke oven 31 is under maintenance, in order to reduce the mixing of tamped coke and top-charged coke in the third dry quenching coke oven 33, the time difference between the loading and unloading of tamped coke is calculated based on the structural characteristics of the third dry quenching coke oven 33 and the coke discharge time and speed. After the top-charged coke in the third dry quenching coke oven 33 is discharged as much as possible, the operating direction of the second conveyor belt 521B is switched, and the third dry quenching coke oven 33 receives the tamped coke and merges it into the tamped coke processing system.

[0067] Furthermore, such as Figure 3 , Figure 11 and Figure 12As shown, the first conveyor belt group 51 and the second conveyor belt group 52 are connected by a third conveyor belt group 53. The third conveyor belt group 53 facilitates the transport of tamped coke to the first conveyor belt group 51. When the first dry quenching coke oven 31 is under maintenance, the third conveyor belt group 53 operates. Of course, it is also possible to omit the third conveyor belt group 53 and directly connect the second conveyor belt group 521B, which can run in reverse, to the first conveyor belt group 51. Specifically, this can be achieved by setting up a chute connection, whereby the second conveyor belt 521B transports the tamped coke to the first conveyor belt group 51. The specific connection method needs to be determined based on the actual routing conditions on site.

[0068] Furthermore, such as Figure 4 , Figure 11 and Figure 12 As shown, the second conveyor belt group 52 includes several conveyor belt units, each of which includes two conveyor belts. The two conveyor belts are configured to serve as backups for each other, reducing the failure rate and ensuring normal production. To meet the conveying needs of the two conveyor belts, the chutes between adjacent conveyor belt units in the second conveyor belt group 52 are all double-forked chutes. Figure 4 The second conveyor belt assembly 52 shown includes a first belt unit 521, a second belt unit 522, and a third belt unit 523. The first belt unit 521 includes a first conveyor belt 521A and a second conveyor belt 521B, as shown below. Figure 5 As shown, the first conveyor belt 521A and the second conveyor belt 521B are located below the second dry quenching coke oven 32 and the third dry quenching coke oven 33. The second belt unit 522 includes the third conveyor belt 522A and the fourth conveyor belt 522B, and the third belt unit 523 includes the fifth conveyor belt 523A and the sixth conveyor belt 523B. The first belt unit 521 transports the top-loaded coke to the second belt unit 522, the second belt unit 522 transports the top-loaded coke to the third belt unit 523, and then to the top-loaded coke processing device. Specifically, the first belt unit 521, the second belt unit 522, and the third belt unit 523 can be connected sequentially via chutes, and the specific connection method can be determined according to the actual site conditions.

[0069] Furthermore, such as Figures 3-7 and Figure 12As shown, when the first dry quenching coke oven 31 is under maintenance, in order to adjust the transport direction and facilitate the transport of compacted coke to the third conveyor belt group 53, a first transfer station J21 is set between the first belt unit 521 and the third conveyor belt group 53. A conveyor belt capable of reversing direction is connected to the first transfer station J21, that is, the second conveyor belt 521B is connected to the first transfer station J21. A chute is provided at the end of the second conveyor belt 521B, and the chute is connected to the third conveyor belt group 53. The second conveyor belt 521B transports the compacted coke through the chute to the third conveyor belt group 53. A chute is provided at the end of the third conveyor belt group 53, and the third conveyor belt group 53 continues to transport the compacted coke through the chute to the first conveyor belt group 51. Preferably, the first transfer station J21 is arranged adjacent to the third dry quenching coke oven 33. It should be noted that the first transfer station J21 is set up to change the transport direction, and the specific setting depends on the coke transport route, generally at the bend in the coke transport route. In order to remove dust from the transported tamped coke, a dust removal system is also installed in the first transfer station J21.

[0070] Furthermore, such as Figures 3-4 , Figures 9-12 As shown, to change the transport direction, a second transfer station J22 and a third transfer station J23 are provided between the third conveyor belt group 53 and the first conveyor belt group 51. The third transfer station J23 is located at the connection point between the third conveyor belt group 53 and the first conveyor belt group 51. The third conveyor belt group 53 includes a fourth belt unit 531 and a fifth belt unit 532. The tamped coke transported by the second conveyor belt 521B is sequentially transported to the first transfer station J21, the fourth belt unit 531, the second transfer station J22, the fifth belt unit 532, the third transfer station J23, and the first conveyor belt group 51. A chute is provided between the second conveyor belt 521B and the fourth belt unit 531, between the fourth belt unit 531 and the fifth belt unit 532, and between the fifth belt unit 532 and the first conveyor belt group 51. It should be noted that the locations of the second transfer station J22 and the third transfer station J23 are determined based on the coke transport route. They are typically set at bends to change the transport direction. In practical applications, the specific locations can be determined according to the actual coke transport route. Figures 8-10 As shown, the tamped coke transported by the fourth belt conveyor unit 531 merges into the first conveyor belt group 51 via the second transfer station J22, the fifth belt conveyor unit 532, and the third transfer station J23. Further, in some specific embodiments, such as... Figures 3-4 , Figures 11-12As shown, a fourth transfer station J1 is provided between two adjacent conveyor belt units of the second conveyor belt group 52. The figure shows three fourth transfer stations J1: fourth transfer station one J11, fourth transfer station two J12, and fourth transfer station three J13. The three fourth transfer stations J1 can be configured to change direction. Each fourth transfer station J1 is equipped with a chute to facilitate the switching of dry-quenched coke between different conveyor belt units. It should be noted that in practical applications, the specific location of each transfer station and the connection method between each transfer station and the corresponding conveyor belt group can be determined according to the actual coke transport route.

[0071] Furthermore, in some specific embodiments, both conveyor belts in the first belt unit 521 are capable of running in reverse, and both conveyor belts are connected to the first transfer station J21, i.e. Figure 4 The first conveyor belt 521A and the second conveyor belt 521B can both run in reverse. When the first dry quenching coke oven 31 is under maintenance, either the first conveyor belt 521A or the second conveyor belt 521B can be used to transport tamped coke.

[0072] Furthermore, the first conveyor belt group 51 includes one or two conveyor belts; and / or, the third conveyor belt group 53 includes one or two conveyor belts. Figures 11-12 The first conveyor belt group 51 and the third conveyor belt group 53 shown both include one conveyor belt, but can also be configured with two conveyor belts. It should be noted that the first conveyor belt group 51 can utilize the existing conveyor belt for compacting coke, or a new conveyor belt can be constructed, depending on the specific circumstances.

[0073] Furthermore, in order to prevent dry-quenched coke from spilling out and to ensure safe production, the first conveyor belt group 51, the second conveyor belt group 52 and the third conveyor belt group 53 are all equipped with sealed passageways.

[0074] It should be noted that the decision to retain the original wet quenching device 2 can be made based on the actual situation. Figure 3 The original wet quenching device 2 is shown in the diagram.
