Description

Technical Field

[0001] The present application relates to the technical field of red coke dry quenching, and more specifically, to a coke transportation system. Background Art

[0002] At present, independent coking enterprises mostly use ramming coke ovens. In the early stage of plant construction, environmental protection regulations are relatively loose, and wet quenching is adopted. With the introduction of environmental protection regulations and the increase in energy management requirements, the advantages of dry quenching in pollutant emissions, energy recovery and coke quality have gradually emerged. Coking enterprises using wet quenching have completed the first round of technical transformation work, and added a set of dry quenching coke ovens on the basis of the original wet quenching equipment. The wet quenching equipment is used during the annual inspection of the dry quenching coke ovens.

[0003] With advances in advanced coking technology and increasingly stringent environmental regulations, some provinces have mandated that new coke ovens utilize full dry quenching (DQ) and that existing coke plants complete this upgrade within a specified timeframe. For coke plants that have completed the first round of DQ upgrades, this means abandoning their existing wet quenching system and installing a new set of DQ coke ovens, along with supporting utilities and DQ coke handling equipment, interconnecting with the existing system.

[0004] Due to changes in various factors such as the development of coking technology, customer demand and coal blending costs, some independent coking enterprises that use ramming coke ovens are seeking transformation and upgrading. They are maintaining stable production of existing ramming coke ovens, building a new group of top-charging coke ovens, producing top-charging coke, and developing the top-charging coke market.

[0005] Using two groups of coke ovens, top-loading coke ovens and ramming coke ovens, in the same site and achieving full dry quenching of coke will face the problems of narrow site, high investment and complex coke transportation system. For upgrading and renovation projects, the renovation is relatively difficult and the original production system will face a long period of shutdown, affecting the service life of the original coke ovens.

[0006] Conventional methods for achieving full CDQ in two different coke oven groups often employ two CDQ ovens per group. These ovens operate independently, eliminating the need for switching between top-loading and tamping CDQ. However, this approach carries high investment costs, and the two CDQ ovens serve as backup, resulting in low utilization.

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

DETAILED DESCRIPTION

[0044] Glossary:

[0045] Top-charging coke oven and ramming coke oven: two coke ovens with different coal loading methods, different coal ratio schemes, and different quality of coke produced. Coke produced by ramming coke oven is suitable for small and medium-sized blast furnaces, while coke produced by top-charging coke oven is suitable for large blast furnaces.

[0046] Coke dry quenching: uses inert circulating gas to cool the high-temperature coke, recovers the sensible heat of the red coke, releases the heat in the boiler, and produces high-temperature and high-pressure steam for power generation.

[0047] Full dry quenching: multiple sets of dry quenching devices are set up. All of them are used during normal production. When one of the dry quenching devices is under maintenance or in an accident state, the remaining dry quenching devices can meet the normal production operation of the coke oven.

[0048] Quenching car track: the track for transporting coke tank carriers, located on one side of the coke oven. The quenching car travels back and forth between the quenching device and the coke oven on this track.

[0049] Coke screening building: This building is used for screening coke. Coke is classified according to size requirements into coke lumps (size > 25mm), coke pieces (size 10mm-25mm), and coke fines (size < 10mm). The upper section of the coke screening building is equipped with a vibrating screen, dry quenching coke chute, and dust removal facilities. The middle section houses temporary storage bins for each level of coke, and the lower section is equipped with a coke discharge gate. Coke of each level is regularly loaded onto trucks for sale.

[0050] Coke storage silo: used to store coke blocks. Depending on the scale of coke production and the arrival time of trains, 15 to 25 coke silos are set up. The upper part is equipped with a mobile unloading car, conveyor belt and dust removal components. The middle part is a coke storage silo and the lower part is equipped with a coke discharge gate. Coke is loaded onto trucks for sale regularly.

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

[0052] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] like Figure 1 and Figure 3 As shown, an embodiment of the present application discloses a coke transportation system, including a first coke oven 10, a second coke oven 20, a dry quenching coke oven group 30, a first quenching car track 40 and a second quenching car track 50, an elevator assembly 80, a conveying assembly 60 and a dry quenching coke processing assembly 70.

[0054] The first quenching car track 40 and the second quenching car track 50 are arranged collinearly or in parallel. Figure 1 The collinear arrangement is shown in Figure 3As shown in FIG, a parallel arrangement is shown. Coke can carriers 90 are located on both the first and second quenching car tracks 40 and 50. These can carriers carry coke cans 91, which are used to hold red coke. An elevator assembly 80 is located between the CDQ coke oven battery 30 and the corresponding first and second quenching car tracks 40 and 50. The elevator assembly 80 is capable of lifting and transporting the coke cans 91 to the top of the CDQ coke oven battery 30, where the red coke is introduced into the CDQ coke oven battery 30 for dry quenching.

[0055] The dry quenching coke oven group 30 includes a first dry quenching coke oven 31, a second dry quenching coke oven 32, and a third dry quenching coke oven 33. The first dry quenching coke oven 31 is arranged on one side of the first quenching car track 40 and performs dry quenching on the red coke of the first coke oven 10. The second dry quenching coke oven 32 and the third dry quenching coke oven 33 are arranged on one side of the second quenching car track 50. The third dry quenching coke oven 33 performs dry quenching on the red coke of the second coke oven 20, and the second dry quenching coke oven 32 performs dry quenching on the red coke of the first coke oven 10 or the second coke oven 20. Preferably, when the first quenching car track 40 and the second quenching car track 50 are arranged in parallel, the first dry quenching coke oven 31, the second dry quenching coke oven 32, and the third dry quenching coke oven 33 are respectively located in the outer area of the area between the first quenching car track 40 and the second quenching car track 50. The conveying assembly 60 conveys the dry quenching coke produced by the first dry quenching coke oven 31 , the second dry quenching coke oven 32 and the third dry quenching coke oven 33 to the dry quenching coke processing assembly 70 .

[0056] In actual use, the red coke produced by the first coke oven 10 is loaded into a coke drum 91. The coke drum carrier 90 carries the coke drum 91 along the first quenching car track 40 to the first dry quenching coke oven 31. The elevator assembly 80 lifts the coke drum 91 and transports it above the first dry quenching coke oven 31. The red coke is then introduced into the first dry quenching coke oven 31 for dry quenching. The dry quenched coke produced by the first dry quenching coke oven 31 is then transported to the dry quenching coke processing assembly 70 via the conveyor assembly 60. The specific transportation and processing process of the red coke produced by the second coke oven 20 is the same as described above and will not be repeated here.

[0057] According to actual work needs, the second dry quenching coke oven 32 can dry quench the red coke produced by the first coke oven 10 or the second coke oven 20. For example, when the first dry quenching coke oven 31 needs to be overhauled and maintained, the second dry quenching coke oven 32 dry quenches the red coke produced by the first coke oven 10; when the third dry quenching coke oven 33 needs to be overhauled and maintained, the second dry quenching coke oven 32 dry quenches the red coke produced by the second coke oven 20; when the first dry quenching coke oven 31 and the third dry quenching coke oven 33 are working at the same time, the second dry quenching coke oven 32 regularly switches the red coke treatment of the first coke oven 10 and the second coke oven 20 to alleviate the aggravated equipment wear and aging caused by the long-term full-load operation of the first dry quenching coke oven 31 and the third dry quenching coke oven 33.

[0058] The coke transportation system disclosed in the embodiment of the present application has three dry quenching coke ovens, namely the first coke oven 10 and the second coke oven 20. The second dry quenching coke oven 32 can dry quench the red coke produced by the first coke oven 10 or the second coke oven 20. The system can be switched according to actual work needs to meet the full dry quenching requirements of the first coke oven 10 and the second coke oven 20. At the same time, when any of the dry quenching coke ovens is undergoing maintenance, the remaining two dry quenching coke ovens can meet the full load production requirements of the first coke oven 10 and the second coke oven 20. Compared with the existing solution of building two dry quenching coke ovens for the first coke oven 10 and the second coke oven 20 respectively, the system can reduce the floor space and equipment investment. The three dry quenching coke ovens serve as backup for each other, which can give full play to the processing capacity of each dry quenching coke oven, improve the utilization efficiency of the dry quenching coke ovens, and alleviate the problem of long-term low-load operation of the dry quenching coke ovens under the full dry quenching regulations. The system can be used for new coking projects or for upgrading and renovating coking projects.

[0059] Furthermore, the number of coke tank carriers 90 on the first quenching car track 40 and the second quenching car track 50 can be set to one or more, preferably two, and the two coke tank carriers 90 operate alternately. When one coke tank carrier 90 reaches the bottom of the elevator assembly 80, the other coke tank carrier 90 returns to the first coke oven 10 or the second coke oven 20 for coking to ensure continuous production.

[0060] Further, if Figure 1 、 Figure 3 and Figure 6 As shown, the hoist assembly 80 includes a first hoist derrick 81, a second hoist derrick 82 and a third hoist derrick 83. Hoists 84 are provided on the first hoist derrick 81, the second hoist derrick 82 and the third hoist derrick 83. The first hoist derrick 81 is arranged between the first dry quenching coke oven 31 and the first quenching coke car track 40, and the third hoist derrick 83 is arranged between the third dry quenching coke oven 33 and the second quenching coke car track 50. The second hoist derrick 82 is arranged between the first quenching coke car track 40 and the second dry quenching coke oven 32. When the first quenching coke car track 40 and the second quenching coke car track 50 are arranged in parallel, the second hoist derrick 82 spans the second quenching coke car track 50 to facilitate the hoist 84 on the second hoist derrick 82 to lift the coke tank 91 on the first quenching coke car track 40 or the second quenching coke car track 50.

[0061] Furthermore, the first coke oven 10 is a stamp-charged coke oven or a top-charged coke oven, and the second coke oven 20 is a stamp-charged coke oven or a top-charged coke oven. The number of first coke ovens 10 may be one or two, and the number of second coke ovens 20 may be one or two, which can be determined based on actual needs. The coke transportation system disclosed in the embodiments of the present application can be applied to two groups of coke ovens transporting the same coke, and can also be applied to two groups of coke ovens producing different cokes.

[0062] Further, if Figures 1-4 As shown, in some specific embodiments, the first coke oven 10 is a ram-charged coke oven, and the second coke oven 20 is a top-charged coke oven. The conveying assembly 60 includes a first conveying assembly 61, a second conveying assembly 62, and a third conveying assembly 63. The CDQ coke processing assembly 70 includes a first CDQ coke processing assembly 71 and a second CDQ coke processing assembly 72. The first conveying assembly 61 is disposed below the CDQ coke oven group 30. The second conveying assembly 62 is connected to the first conveying assembly 61 and transports the CDQ coke to the first CDQ coke processing assembly 71, which is a ram-charged coke processing assembly. The third conveying assembly 63 is connected to the first conveying assembly 61 and transports the CDQ coke to the second CDQ coke processing assembly 72, which is a top-charged coke processing assembly. The coke transportation system disclosed in the embodiments of the present application can meet the transportation needs of two different types of coke, ram-charged coke and top-charged coke, ensuring that different cokes enter their respective processing assemblies and that coke is not mixed during the production process. In order to prevent dust from spreading, the first conveying assembly 61, the second conveying assembly 62 and the third conveying assembly 63 are all provided with sealed corridors. The setting of the sealed corridors can meet environmental protection requirements, while isolating external humidity, rainwater and other interferences, preventing dry quenching coke from absorbing water, and ensuring the smelting quality of the blast furnace.

[0063] Further, if Figure 2 and Figure 4 As shown, in order to adapt to the coke transportation route, reduce the failure rate of the coke transportation system, and ensure safe operation, the second conveying assembly 62 and the third conveying assembly 63 each include a number of conveying units J1 and a number of transfer stations J2. Each conveying unit J1 includes two conveyor belts, and the two conveyor belts serve as backup for each other. When one of them fails, the other can meet the normal needs of coke transportation. Of course, each conveying unit J1 can also include only one conveyor belt. The transfer station J2 is set between two adjacent conveying units J1. Each transfer station J2 includes a chute and a dust removal component to adapt to the turning in the coke transportation route or the temporary storage needs of coke. In order to meet the transportation needs of the two conveyor belts, the chute at the tail of the conveyor belt of each conveyor unit J1 adopts a double-fork chute to connect with the head of the conveyor belt of the adjacent conveyor unit J1. It should be noted that the specific number and location of the transfer station J2 need to be determined in combination with the actual project requirements.

[0064] Specifically, such as Figure 1-Figure 2As shown, when the first quenching car track 40 and the second quenching car track 50 are arranged in the same line, the second conveying assembly 62 shown in the figure includes four transfer stations J2, namely the first transfer station J211, the second transfer station J212, the third transfer station J213 and the fourth transfer station J214, and the third conveying assembly 63 includes four transfer stations J2, namely the fifth transfer station J221, the sixth transfer station J222, the seventh transfer station J223 and the eighth transfer station J224. Figure 3-Figure 4 As shown, when the first quenching car track 40 and the second quenching car track 50 are arranged in parallel, the second conveying assembly 62 further includes the ninth transfer station J231, the tenth transfer station J232, the eleventh transfer station J233, the twelfth transfer station J234, the thirteenth transfer station J235 and the fourteenth transfer station J236; the third conveying assembly 63 includes the fifteenth transfer station J241, the sixteenth transfer station J242, the seventeenth transfer station J243 and the eighteenth transfer station J244, the fourteenth transfer station The transport station J236 is arranged between the second coke oven 20 and the tenth transfer station J232. The fourth conveyor belt 612B, which can run in the reverse direction, is connected to the fourteenth transfer station J236. That is, when the first dry quenching coke oven 31 is overhauled and maintained, the second dry quenching coke oven 32 dry quenches the red coke of the first coke oven 10. The dry quenched coke produced by the second dry quenching coke oven 32 is discharged to the fourth conveyor belt 612B and transported to the second conveying assembly 62 via the fourteenth transfer station J236 and the tenth transfer station J232.

[0065] Further, if Figure 1 and Figure 2 As shown in the figure, the first quenching car track 40 and the second quenching car track 50 are arranged in the same line, and the first dry quenching coke oven 31, the second dry quenching coke oven 32 and the third dry quenching coke oven 33 are arranged on the same side of the first quenching car track 40 and the second quenching car track 50. Of course, what is shown in the figure is only an example. The first dry quenching coke oven 31, the second dry quenching coke oven 32 and the third dry quenching coke oven 33 can also be arranged on the opposite side of the first quenching car track 40 and the second quenching car track 50. For example, the first dry quenching coke oven 31 is located at Figure 1 The second dry quenching coke oven 32 and the third dry quenching coke oven 33 are located below the first quenching car track 40 shown in FIG. Figure 1 The specific location can be determined based on the actual project requirements.

[0066] The first conveyor assembly 61 is disposed below the first dry quenching coke oven 31, the second dry quenching coke oven 32, and the third dry quenching coke oven 33. The first conveyor assembly 61 includes a first conveyor belt 61A and a second conveyor belt 61B. Both the first conveyor belt 61A and the second conveyor belt 61B are capable of bidirectional operation. Specifically, taking the first conveyor belt 61A as an example, the first conveyor belt 61A is disposed between a drive roller and a redirecting roller. The drive roller is driven by a drive motor to rotate, thereby driving the first conveyor belt 61A to rotate. The conveying direction of the first conveyor belt 61A can be changed by changing the direction of the drive motor. The structure and principle of the second conveyor belt 61B are similar to those of the first conveyor belt 61A. The specific structure and principle of each conveying unit of the second conveyor assembly 62 and the third conveyor assembly 63, as well as the specific structure and principle of the first conveyor assembly 61, can be found in the structural composition and working principle of existing conveyor belts and will not be described in detail here. Specifically, the first conveyor belt 61A can be used to convey rammed coke, and the second conveyor belt 61B is used to convey top-loaded coke. The coke types processed by the first dry quenching coke oven 31, the second dry quenching coke oven 32 and the third dry quenching coke oven 33 are discharged onto corresponding conveyor belts respectively.

[0067] Further, if Figure 3 As shown, the first quenching car track 40 and the second quenching car track 50 are arranged in parallel, the first coke oven 10 is set at one end of the first quenching car track 40, the second coke oven 20 is set at one end of the second quenching car track 50, and the first dry quenching coke oven 31, the second dry quenching coke oven 32 and the third dry quenching coke oven 33 are all located outside the first quenching car track 40 and the second quenching car track 50, that is, outside the area between the first quenching car track 40 and the second quenching car track 50. It should be noted that Figure 3 The specific positions of the first dry quenching furnace 31, the second dry quenching furnace 32 and the third dry quenching furnace 33 shown in the figure are only examples. The first dry quenching furnace 31 and the third dry quenching furnace 33 can also be arranged symmetrically. The specific setting positions can be determined in combination with actual project requirements.

[0068] like Figure 4 As shown, the first conveying assembly 61 includes a first conveying portion 611 and a second conveying portion 612. The first conveying portion 611 is arranged below the first dry quenching coke oven 31, and the second conveying portion 612 is arranged below the second dry quenching coke oven 32 and the third dry quenching coke oven 33. The second conveying portion 612 includes a third conveyor belt 612A and a fourth conveyor belt 612B. At least one of the third conveyor belt 612A and the fourth conveyor belt 612B can run in both directions, and the one that can run in both directions is connected to the second conveying assembly 62. For the convenience of explanation, the fourth conveyor belt 612B is defined as being able to run in both directions.

[0069] When the first CDQ coke oven 31 undergoes maintenance and overhaul, the second CDQ coke oven 32 performs CDQ on the red coke from the first coke oven 10. The hoist 84 on the second hoist derrick 82 lifts the coke drum 91 from the first quenching car track 40 and transports it to the second CDQ coke oven 32 for CDQ. The resulting rammed coke is discharged onto the fourth conveyor belt 612B, which runs leftward and transports the CDQ coke to the second conveyor assembly 62, from which it is further transported to the first CDQ coke processing assembly 71. The top-loaded coke from the third CDQ coke oven 33 is discharged onto the third conveyor belt 612A, which runs rightward and transports the top-loaded coke to the third conveyor assembly 63, from which it is further transported to the second CDQ coke processing assembly 72. The third conveyor belt 612A and the fourth conveyor belt 612B operate simultaneously, but in opposite directions.

[0070] When the second dry quenching coke oven 32 and the third dry quenching coke oven 33 both perform dry quenching on the red coke from the second coke oven 20, only one of the third conveyor belt 612A and the fourth conveyor belt 612B can be operated, or both can be operated simultaneously. When operating simultaneously, both have the same operating direction, i.e., rightward.

[0071] Further, if Figure 5 and Figure 6 As shown, the second hoist derrick 82 includes a hoist shaft 821 arranged vertically and a hoist track 822 arranged horizontally. The hoist shaft 821 includes two parts located at the first quenching car track 40 and the second quenching car track 50. The hoist shaft 821 is preferably composed of steel structural parts. The hoist track 822 is set between the tops of the two hoist shafts 821, and the hoist 84 can move along the hoist track 822. In order to prevent the hoist 84 from derailing when running along the hoist track 822, both ends of the hoist track 822 are provided with a limit structure and an anti-collision structure. Specifically, the limit structure and the anti-collision structure can be used in combination, using the same part or different parts. For example, the limit structure can use a rigid block, and the anti-collision structure can use a rubber block, or a buffer pad can be set on the rigid block; alternatively, the limit structure can use a travel switch. The specific setting method can be determined according to actual conditions.

[0072] Furthermore, to ensure that the coke canister carrier 90 stops correctly and that the coke canister 91 can fall onto the hook 843 of the elevator 84, positioning members are provided on both the first quenching car track 40 and the second quenching car track 50. These members ensure that the coke canister carrier 90 reaches the bottom of the hoist shaft 821 and is aligned with the elevator 84. Specifically, the positioning members can be centering clamping devices. When the coke canister carrier 90 stops, the centering clamping devices clamp the protruding structures on the coke canister carrier 90 from both sides. Alternatively, the positioning members can be travel switches or centering sensors, such as laser or infrared sensors, connected to the control components of the elevator 84.

[0073] Furthermore, in order to collect the smoke and dust emitted during the transportation of the coke drum 91, Figure 7 As shown, a coke drum dust hood 841 is installed on the elevator 84. The drum dust hood 841 is preferably detachably connected to the elevator 84 to facilitate replacement and removal of the drum dust hood 841; alternatively, the drum dust hood 841 is hingedly connected to the elevator 84. Preferably, the drum dust hood 841 covers at least the drum lid 91. Specifically, the drum dust hood 841 should be slightly larger than the drum lid to collect pollutants released from the gap between the drum lid and the drum 91 and the pressure relief holes in the drum lid. A drum dust removal duct 842 is installed on the elevator track 822. The drum dust hood 841 is connected to the drum dust removal duct 842 via a connecting pipe. The drum dust removal duct 842 is connected to the dust removal system of the dry quenching coke oven 30. The drum dust removal duct 842 is sealed with a sealing belt, which is connected to a sealing trolley that can move along the elevator track 822. Preferably, the sealing trolley moves synchronously with the elevator 84.

[0074] During transport, coke drum 91 cannot be sealed. The red coke inside remains hot, releasing high-temperature smoke and dust, polluting the air. A coke drum dust hood 841 collects the smoke and dust that escapes during transport. The smoke and dust are then transported via a connecting pipe to a coke drum dust removal duct 842, which runs along the elevator track 822. The duct 842 is sealed with a belt. Specifically, the connecting pipe is inserted into the duct 842 and can move axially along the duct. As the elevator 84 moves, a sealing trolley moves synchronously to seal the duct 842. Preferably, the sealing belts are arranged in a "J" shape, with the connection between the connecting pipe and the duct 842 positioned below the belts. In other embodiments, a water seal may also be used. Flue gas from the duct 842 is then fed into the dry quenching coke oven's dust removal system for purification and discharge. The setting of the coke tank dust collecting hood 841 can collect pollutants emitted during the movement of the coke tank 91 along the elevator track 822, thereby reducing the emission of pollutants.

[0075] Further, if Figure 8 and Figure 9 As shown, to enhance safety and reliability during the transfer of the coke drum 91, at least two hooks 843 are provided on either side of the elevator 84, and the coke drum 91 is provided with lifting lugs that mate with the hooks 843. As shown in the figure, two hooks 843 are provided on either side of the elevator 84, and two lifting lugs that mate with the hooks 843 are provided on each side of the coke drum 91. This arrangement of two sets of hooks 843 ensures that if one set of hooks 843 fails, the other set can still operate normally, thus reducing the possibility of the coke drum 91 falling due to hook 843 failure.

[0076] Further, if Figure 8 As shown, to detect the connection between the hook 843 of the hoist 84 and the lug on the coke drum 91, the hoist 84 is provided with a hook state detection element 844. The hook state detection elements 844 are preferably located on either side of the coke drum 91, aligned with the position of the hook 843. The hook state detection elements 844 are connected to the control component of the hoist 84. When the hook state detection elements 844 detect that the hook 843 is connected to the coke drum 91, they transmit a signal to the control component of the hoist 84. The control component sends a signal to the hoist 84, which then lifts the coke drum 91. While the hoist 84 is operating with the coke drum 91, the hook state detection elements 844 can also monitor the status of the hook 843 in real time. If an abnormality is detected, the hook state detection elements 844 send a signal to the control component of the hoist 84, instructing the hoist 84 to respond. Specifically, the hook state detection elements 844 preferably employ visual sensors that detect the status of the hook 843 through image recognition.

[0077] Furthermore, to ensure safety during the transfer of coke drums 91 by the elevator 84 and to reduce the risk of coke and coke drums 91 falling during high-altitude transportation, safety guardrails are installed on both sides of the bottom of the first elevator derrick 81, the second elevator derrick 82, and the third elevator derrick 83. Specifically, the safety guardrails are retractable. When the coke drum 91 is being transferred, the safety guardrails are closed to prevent pedestrians and vehicles from passing through. When the coke drum 91 is not being transferred, the safety guardrails are opened to allow vehicles and pedestrians to pass normally. A coke drum protective cover is installed on the second elevator derrick 82. The coke drum protective cover preferably adopts a hollow structure such as a grating plate to reduce the wind resistance of the elevator derrick at high altitude. The coke drum protective cover is preferably arranged along the direction of the elevator track 822 and is preferably made of a high-temperature resistant material with a U-shaped cross-section. The coke drum 91 moves within the coke drum protective cover to prevent the coke drum 91 and the red coke from falling. Furthermore, to serve as a warning, a warning sign can be placed on the safety guardrail.

[0078] Furthermore, to ensure the normal operation of elevator 84 and enhance its reliability and continuity, elevator 84 utilizes a dual-power drive. Specifically, elevator 84 includes a first drive module and a second drive module, which can operate in parallel or independently. Both the first and second drive modules are preferably motors. During normal operation, the two motors operate simultaneously, ensuring that elevator 84 operates at its rated speed. If one of the first and second drive modules fails, the other can drive elevator 84 to continue operating.

[0079] Furthermore, the dry quenching coke processing assembly 70 includes a coke screening building and a coke storage bin. Specifically, the first dry quenching coke processing assembly 71 includes a ramming coke screening building 711 and a ramming coke storage bin 712. Figure 2 As shown, the stamping coke screening building 711 is located between the third transfer station J213 and the fourth transfer station J214. The second CDQ coke processing assembly 72 includes a top-loading coke screening building 721 and a top-loading coke storage bin 722. The top-loading coke screening building 721 is located between the seventh transfer station J223 and the eighth transfer station J224.
