Description

Technical Field

[0001] The present application belongs to the field of coking branch technology, and specifically relates to a double-branch chute and a coke dry quenching device. Background Art

[0002] In the field of CDQ production, efficient and stable material transfer plays a key role in the smooth operation of the entire production process. Among them, the double-branch chute, as the core mechanism for controlling material transfer, occupies an important position in the CDQ production line. Usually, the double-branch chute is installed on the upper part of the belt conveyor system and is closely linked with the belt unit. It is responsible for accurately diverting the CDQ coke to different belts and then transporting it to subsequent processing or storage links.

[0003] At present, most of the double-branch chutes widely used in dry coke quenching production lines adopt a flap structure. This flap-type double-branch chute controls the opening and closing status of the two chute pipes through a flap. However, this structure has obvious defects. On the one hand, it cannot open or close the two chute pipes at the same time, which greatly limits its flexibility in maintenance work. In actual production, when a chute pipe needs to be repaired, the two pipes cannot be closed at the same time, making the maintenance work extremely complicated, which not only prolongs the maintenance time, but also increases safety hazards.

[0004] On the other hand, the flap-type double-branch chute places the rotating shaft inside the chute pipe, which brings many problems in the actual operation process. The coke will produce a large resistance during the falling process, and the rotating shaft needs to overcome this resistance to realize the rotation of the flap, which not only increases the energy consumption of the equipment, but also easily causes the flap to move unsmoothly. What is more serious is that in the long-term production process, the flap is very easy to be stuck by the falling coke, resulting in the chute pipe cannot be completely sealed. Once this happens, it will not only affect the normal transportation of coke and reduce production efficiency, but also cause a large amount of dust to overflow, causing serious pollution to the production environment, but also increase the maintenance cost and difficulty of the equipment. Summary of the invention

[0005] In view of this, the present application provides a double-branched chute and a dry coke quenching device, which can achieve precise control of the simultaneous opening or closing of two chute pipelines, and at the same time ensure that the two chute pipelines are completely closed when closed.

[0006] In order to achieve the above objectives, this application mainly provides the following technical solutions:

[0012] Optionally, at least two adjustment plates are rotatably provided on the inner wall of the adjustment groove, and at least two of the adjustment plates are located on the side of the gate away from the coke discharge port and extend along the moving direction of the gate. When the gate moves to the first extreme position, the free ends of at least two of the adjustment plates cooperate with the gate to seal the gap between the gate and the adjustment groove.

[0013] Optionally, a limit block is provided at the free end of the gate, and when the gate moves to the second limit position, the limit block abuts against the inner wall of the adjustment groove.

[0014] Optionally, sealing gaskets are provided at the connection between the sealing valve and the main chute, the connection between the main chute and the three-way chute, the connection between the three-way chute and the first branch chute and the second branch chute, and the connection between the first branch chute and the second branch chute and the adjusting chute.

[0015] Optionally, a material-blocking step is provided at a position in contact with the coke in the inner wall of the first branch chute and the second branch chute. The material-blocking step is a staggered structure and is used to change the falling trajectory and speed of the coke so that the coke collides and rubs against each other during the falling process.

At the same time, the gate is a flat structure, located on the upstream side of the coke discharge port. Compared with the traditional flap structure in which the rotating shaft is placed inside the chute pipeline, the gate is prevented from being stuck by coke, so that the gate is not disturbed by the direct impact and resistance of the falling coke, and can be opened and closed more stably and smoothly, ensuring the long-term stable operation of the equipment.

[0031] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0032] A first aspect of an embodiment of the present application provides a double-branched chute, and a second aspect of an embodiment of the present application provides a coke dry quenching device.

[0033] Among them, the double-branch chute is used in the dry quenching device.

[0034] Specifically, in actual applications, the dry coke quenching device is used to cool the hot coke. After the coke is cooled to a suitable temperature, it will be discharged from the sealing valve of the dry coke quenching device. At this time, the double-branch chute closely connected to the sealing valve begins to play a role. The double-branch chute is used to stably receive the cooled coke discharged from the sealing valve to ensure that the coke can smoothly enter the subsequent transportation link and avoid problems such as spilling and accumulation of coke during the discharge process that affect production continuity. It is understandable that in the transportation link of coke, it is usually necessary to transport the cooled coke to different storage areas or to different processing procedures to meet the subsequent diversified production needs. After receiving the coke, the double-branch chute accurately diverts the flow according to the production instructions, flexibly controls the opening and closing status of the two chute pipes, thereby realizing the directional transportation of coke and ensuring that each production link can obtain the required amount of coke in a timely and accurate manner.

[0035] See also Figures 1 to 4 As shown, the double-branch chute provided in the embodiment of the present application includes: a main chute 1, which is connected to the sealing valve of the dry coke quenching device, and the main chute 1 is used to receive the cooled coke; a first fork chute 2 and a second fork chute 3, the first fork chute 2 and the second fork chute 3 are arranged on the downstream side of the main chute 1 along the coke conveying direction, the first fork chute 2 and the second fork chute 3 are connected to the main chute 1 through a three-way chute 4, and the first fork chute 2 and the second fork chute 3 are used to divert the coke; wherein, a gate 5 is provided on the upstream side of the coke discharge port along the coke conveying direction in the first fork chute 2 and the second fork chute 3, and the gate 5 is connected to the control device 6, and the control device 6 is used to control the opening and closing of the gate 5.

[0036] In this embodiment, the first forked chute 2 and the second forked chute 3 are connected to the main chute 1 through the three-way chute 4, and the cooled coke can be accurately diverted to different paths according to actual production needs. At the same time, the first forked chute 2 and the second forked chute 3 are both provided with a gate 5 connected to the control device 6 on the upstream side of the coke discharge port along the coke transport direction, so that the gates 5 of the first forked chute 2 and the second forked chute 3 can be independently controlled to open and close. Compared with the traditional structure that cannot control the opening and closing of two chute pipelines at the same time, the maintenance time is greatly shortened, the maintenance efficiency is improved, and the impact on the overall production is reduced. At the same time, the gate 5 is a flat structure, located on the upstream side of the coke discharge port. Compared with the traditional flap structure in which the rotating shaft is placed inside the chute pipeline, the gate 5 is prevented from being stuck by coke, so that the gate 5 is not disturbed by the direct impact and resistance of the falling coke, and can be opened and closed more stably and smoothly, ensuring the long-term stable operation of the equipment.

[0037] Among them, the main chute 1 is the starting key part of the entire double-branch chute, and one end is closely connected to the sealing valve of the dry coke quenching device. In the dry coke quenching process, the hot coke is discharged from the sealing valve of the dry coke quenching device after cooling. The main chute 1 can play the role of receiving these cooled cokes and prepare for the subsequent diversion and transportation. In other words, the main chute 1 is the main entrance channel of the entire double-branch chute, which can ensure that the cooled coke can smoothly enter the double-branch chute.

[0038] Specifically, a connecting flange is provided at one end of the main chute 1 close to the sealing valve, and the main chute 1 is tightly connected to the sealing valve of the dry coke quenching device through the connecting flange and bolts.

[0039] Among them, the first forked chute 2 and the second forked chute 3 are the core components for realizing the diversion of coke. They are located on the downstream side of the main chute 1 along the conveying direction of coke, and are connected to the main chute 1 through the three-way chute 4, so that the coke conveyed from the main chute 1 can be distributed to different paths according to production needs. For example, in actual production, the first forked chute 2 can convey coke to the storage area, and the second forked chute 3 can convey coke to the production line for further processing.

[0040] Among them, the three-way chute 4 is the key connecting hub for realizing the diversion function. Its shape is similar to a "three-way" pipe, which realizes the connection between a main channel (main chute 1) and two branch channels (the first branch chute 2 and the second branch chute 3), ensuring that coke can flow smoothly from the main chute 1 to the first branch chute 2 and the second branch chute 3.

[0041] Specifically, connection flanges are also provided at the connection between the main chute 1 and the three-way chute 4, and at the connection between the three-way chute 4 and the first forked chute 2 and the second forked chute 3. When assembling the double-forked chute, the connection flanges of the corresponding parts are aligned, and the double-forked chute can be quickly spliced ​​by connecting bolts and nuts.

[0042] Among them, gates 5 are installed at the upstream position of the coke discharge port along the coke conveying direction in the first branch chute 2 and the second branch chute 3. These gates 5 control the flow of coke in the branch chute just like valves controlling water flow. When the gates 5 are opened, the coke can be smoothly conveyed to the designated location through the branch chute; when the gates 5 are closed, the coke cannot pass through, thereby realizing the control of the coke conveying in the branch chute.

[0043] Specifically, the gate 5 is a flat structure, and the moving path of the gate 5 is perpendicular to the conveying direction of the coke. In practical applications, when the gate 5 is driven to move, since the moving path of the gate 5 is perpendicular to the conveying direction of the coke, the gate 5 will not be disturbed by the lateral force generated by the coke flow during the opening or closing process. As a result, the stability and smoothness of the operation of the gate 5 are ensured, the risk of jamming due to external force obstruction is greatly reduced, the stable operation of the double-branch chute is guaranteed, production interruptions caused by equipment failure are avoided, and the continuity and efficiency of the dry quenching production are effectively improved. In addition, the vertical movement method allows the flat gate 5 to fit tightly with the inner wall of the bifurcated chute when closed. Regardless of the flow rate of the coke and the speed of the flow, it can effectively block the leakage of coke and dust, forming a good sealed environment, thereby maintaining the cleanliness of the production environment and reducing the harm of dust to the health of equipment and operators.

[0044] Each gate 5 is connected to a control device 6 in a one-to-one correspondence, so that the operator can individually and accurately control the gates 5 in different branch chutes.

[0045] Specifically, the control device 6 can be a hydraulic push rod, an electric push rod, or a starter push rod. When the control device 6 is a hydraulic push rod, the linear motion of the push rod is achieved by the pressure transmission of the hydraulic oil in the closed system. In actual application, when the operator issues a control command, the oil pump in the hydraulic system delivers the hydraulic oil to the oil cylinder of the hydraulic push rod, pushing the piston to move, and then driving the flat gate 5 connected thereto to move perpendicular to the coke conveying direction.

[0046] In some possible implementations disclosed in this application, see Figure 2 and Figure 4 As shown, an adjusting groove 7 is provided on the upstream side of the coke discharge port along the coke transport direction in the first branch chute 2 and the second branch chute 3, and a gate 5 is movably provided in the adjusting groove 7. The moving path of the gate 5 includes a first extreme position and a second extreme position. When the gate 5 moves to the first extreme position, the gate 5 cuts off the coke flow in the adjusting groove 7, and when the gate 5 moves to the second extreme position, the gate 5 releases the coke flow in the adjusting groove 7.

[0047] In this embodiment, the gate 5 can be moved to different positions in the adjusting groove 7. When it is in different extreme positions, it can completely cut off or release the coke flow in the first branch chute 2 and the second branch chute 3. Combined with the situation where the gate 5 is between the two extreme positions, it can achieve flexible distribution and precise adjustment of the coke flow in the two branch chutes, meet the specific requirements of different production links or different processing units for the amount of coke, and improve the adaptability and controllability of the entire production process.

[0048] The first branch chute 2 and the second branch chute 3 are both provided with an adjustment groove 7 on the upstream side of the coke discharge port in the coke conveying direction. In the embodiment of the present application, the adjustment groove 7 is an independent control area outside the coke discharge port, which provides a special space for the movement of the gate 5, so that the gate 5 can move freely and stably therein, thereby realizing effective control of the coke flow in the branch chute.

[0049] The gate 5 is movably installed in the adjustment groove 7. That is, the gate 5 is not fixed, but can change its position in the adjustment groove 7 according to actual production needs. Specifically, the gate 5 can move on the "track" of the adjustment groove 7 according to a preset path.

[0050] Specifically, a through groove for the gate 5 to give way is provided on one side wall of the regulating groove 7, so as to ensure that the gate 5 can smoothly move back and forth between the first limit position and the second limit position in the regulating groove 7. When the gate 5 is driven by the control device 6 to move to the first limit position, the gate 5 enters the regulating groove 7 through the through groove, and completely cuts off the coke flow in the regulating groove 7. When the gate 5 is driven by the control device 6 to move to the second limit position, the gate 5 withdraws from the regulating groove 7 through the through groove, and completely removes the obstruction to the coke flow in the regulating groove 7.

[0051] In some possible implementations disclosed in this application, see Figure 2 and Figure 4 As shown, at least two adjustment plates 8 are rotatably provided on the inner wall of the adjustment groove 7, and the at least two adjustment plates 8 are located on the side of the gate 5 away from the coke discharge port and extend along the moving direction of the gate 5. When the gate 5 moves to the first extreme position, the free ends of the at least two adjustment plates 8 cooperate with the gate 5 to seal the gap between the gate 5 and the adjustment groove 7.

[0052] In this embodiment, through the close cooperation between the adjustment plate 8 and the gate 5, more accurate flow control can be achieved when the gate 5 cuts off the coke flow. Since the gap is effectively sealed, the coke flow is cut off more thoroughly. When the coke delivery volume needs to be accurately controlled, more accurate control can be provided, which helps to improve the accuracy of coke flow regulation during the dry coke quenching production process and meet the needs of different production processes. At the same time, good sealing can also greatly reduce the escape of coke dust from the gap between the gate 5 and the adjustment slot 7, which is conducive to improving the working environment, reducing the harm of dust to the health of operators, and also reducing the pollution of dust to the surrounding environment.

[0053] In actual application, the double-branch chute is arranged vertically, and the position and movement characteristics of the adjustment plate 8 are significantly affected by gravity. Since the adjustment plate 8 is rotatably arranged on the inner wall of the adjustment groove 7 and is located on the side of the gate 5 away from the coke discharge port, the adjustment plate 8 naturally droops under the continuous action of gravity.

[0054] Specifically, when the gate 5 reaches the first limit position, the adjustment plate 8 is precisely placed on the gate 5 under the action of gravity. At this time, gravity becomes the key force for the adjustment plate 8 to fit tightly with the gate 5, making the contact between the adjustment plate 8 and the gate 5 closer, and effectively eliminating the possible gap between the gate 5 and the adjustment slot 7.

[0055] There are two adjustment plates 8 , which are arranged opposite to each other and extend along the moving direction of the gate 5 to fill the gap that may originally exist between the gate 5 and the adjustment slot 7 .

[0056] Specifically, the connection ends of the two adjustment plates 8 are rotatably connected to the inner wall of the adjustment groove 7 through a rotating shaft. This connection method gives the adjustment plates 8 the characteristic of being able to rotate flexibly. When the double-branch chute is in actual operation, the free ends of the two adjustment plates 8 present a unique posture in opposite directions under the action of their own gravity, and are accurately placed on the gate 5. As a result, when the gate 5 is in the first extreme position, the adjustment plates 8 can fit tightly against the gate 5, effectively filling the gap between the gate 5 and the adjustment groove 7, thereby achieving effective truncation and sealing of the coke flow in the adjustment groove 7, and ensuring the stable operation and efficient work of the entire double-branch chute system.

[0057] In some possible implementations disclosed in this application, see Figure 2 As shown, a limit block 9 is provided at the free end of the gate 5 , and when the gate 5 moves to the second limit position, the limit block 9 abuts against the inner wall of the adjustment groove 7 .

[0058] In this embodiment, when the gate 5 moves to the second extreme position, the limit block 9 abuts against the inner wall of the adjustment groove 7, which can accurately define the position of the gate 5 so that the gate 5 will not completely withdraw from the adjustment groove 7, thereby eliminating the hidden danger of equipment failure caused by excessive movement of the gate 5.

[0059] When the operator controls the gate 5 to move through the operating device 6, the gate 5 moves along a predetermined path in the regulating tank 7. As the operating device 6 continues to exert force, the gate 5 gradually approaches the second limit position. The second limit position is a very important node, which determines the maximum passing state of the coke flow in the regulating tank 7.

[0060] Specifically, when the gate 5 moves to the second extreme position, the limit block 9 arranged at its free end begins to play a role. The limit block 9 will contact and abut against the inner wall of the adjustment groove 7. This abutment is not a simple touch, but has a clear functional orientation. From the actual function point of view, the limit block 9 abuts against the inner wall of the adjustment groove 7, just like setting an "end point" for the movement of the gate 5. It clearly defines the exact position of the gate 5 at the second extreme position, prevents the gate 5 from continuing to move forward under the action of the control device 6, and prevents the gate 5 from completely withdrawing from the adjustment groove 7. Once the gate 5 is completely separated from the adjustment groove 7, it will seriously affect the normal operation of the double-branch chute, resulting in the inability to effectively control the coke flow, and may even cause a safety accident. In addition, the existence of the limit block 9 ensures the stability and repeatability of the equipment operation. Every time the control device 6 drives the gate 5 to reach the second extreme position, the limit block 9 will accurately abut against the inner wall of the adjustment groove 7, so that the position of the gate 5 always remains consistent. This is crucial for accurately controlling the flow and direction of coke, ensuring the stability and reliability of the entire CDQ production process and providing stable material supply conditions for subsequent production links.

[0061] In some possible implementations disclosed in this application, see Figure 1 As shown, sealing gaskets 10 are provided at the connection between the sealing valve and the main chute 1, the connection between the main chute 1 and the three-way chute 4, the connection between the three-way chute 4 and the first branch chute 2 and the second branch chute 3, and the connection between the first branch chute 2 and the second branch chute 3 and the adjusting tank 7.

[0062] In this embodiment, the sealing gasket 10 is provided to fill the tiny gaps at the joints to form a tight sealing structure, which effectively prevents coke and hot gas from leaking to the outside of the system and avoiding pollution to the surrounding environment. It also prevents heat loss and improves energy efficiency.

[0063] Among them, when the connection between the sealing valve and the main chute 1, the connection between the main chute 1 and the three-way chute 4, the connection between the three-way chute 4 and the first forked chute 2 and the second forked chute 3, and the connection between the first forked chute 2 and the second forked chute 3 and the regulating trough 7 are all connected by connecting flanges, a sealing gasket 10 will be set between the two connecting flanges. This sealing gasket 10 is sandwiched between the connecting flanges and can effectively fill the small gap between the connecting flanges to ensure that each connection has good sealing performance, prevent the leakage of coke, hot air or dust from these connections during the coke transportation process, and ensure the stable operation of the entire dry coke quenching system.

[0064] Specifically, the sealing gasket 10 may be a graphite composite sealing gasket 10, a ceramic fiber sealing gasket 10, or a polytetrafluoroethylene (PTFE) sealing gasket 10, etc., which is not limited in the present application.

[0065] In some possible implementations disclosed in this application, see Figure 1 As shown, the inner walls of the first branch chute 2 and the second branch chute 3 are both provided with a material blocking step 11 at the position in contact with the coke. The material blocking step 11 is a staggered structure and is used to change the falling trajectory and speed of the coke so that the coke collides and rubs against each other during the falling process.

[0066] In this embodiment, by setting the material-blocking step 11 to a structure with different heights, the coke that originally fell in a straight line can change its direction of movement, so that the coke forms a complex movement trajectory in the chute, and the coke is prevented from falling in a concentrated position, so that the coke is more evenly distributed in the chute, which is conducive to the stable progress of the subsequent process. At the same time, when the coke hits the material-blocking step 11, its falling speed will change due to the collision, and the falling speed of the coke can be controlled within a suitable range to prevent the coke from causing excessive impact on the bottom of the chute or subsequent equipment due to the excessive falling speed, and to avoid low transportation efficiency due to too slow speed. At the same time, when the coke passes through the material-blocking step 11, due to the change of movement trajectory and speed, different particles of coke will collide and rub against each other, which helps to further break larger coke particles into smaller particles, making the coke particle size more uniform.

[0067] The material-blocking step 11 is arranged at a position where the inner walls of the first branch chute 2 and the second branch chute 3 contact the coke, so that the material-blocking step 11 can directly act on the falling coke.

[0068] The material blocking step 11 is a staggered structure, which is not a smooth or uniform structure, but a stepped structure with different heights. This different height layout can make the coke encounter obstacles of different heights during the falling process, thereby producing different movement changes.

[0069] Specifically, when the coke flows down the chute, it encounters the blocking step 11, and the original straight falling path will be interrupted. Since the height of the blocking step 11 is staggered, the coke will be subjected to forces in different directions at different positions, thereby changing its falling direction, so that the coke no longer falls simply vertically in the chute, but forms a more complex and irregular motion trajectory.

[0070] In some possible implementations disclosed in this application, see Figure 1 As shown, the first branch chute 2 and the second branch chute 3 are both provided with a dust removal port 12, and the dust removal port 12 is used to connect to a dust collector.

[0071] In this embodiment, by setting up the dust removal port 12 and connecting the dust collector, a large amount of dust generated by the coke in the process of falling through the branch chute can be collected in a timely and effective manner to prevent it from being emitted into the surrounding environment, thereby greatly reducing the dust pollution to the air, reducing the dust concentration in the production site and surrounding areas, and improving the air quality.

[0072] In practical applications, both the first branch chute 2 and the second branch chute 3 are provided with dust removal ports 12 to form dust collection channels.

[0073] Specifically, each dust removal port 12 is connected to a dust collector. When the coke falls and flows in the first branch chute 2 and the second branch chute 3, a large amount of dust will be generated due to the collision between the cokes and the friction with the chute wall. At this time, the dust collector is running, and the negative pressure suction force generated by it can suck the dust in the chute into the dust collector along the dust removal port 12.

[0074] In some possible implementations disclosed in this application, see Figure 1 As shown, a hanging frame 13 is provided on the main chute 1, and the hanging frame 13 is used to fix the main chute 1 and the civil foundation, and a supporting frame 14 is provided at a position relative to the three-way chute 4 in the civil foundation, and the supporting frame 14 is used to fix the three-way chute 4.

[0075] In this embodiment, by setting a hanging frame 13 to fix the main chute 1 to the civil foundation, the main chute 1 can maintain a stable position during the transportation of materials such as coke, and will not shake, shift or tilt due to factors such as the weight of the material and the impact force generated by the flow, thereby ensuring the structural stability of the main chute 1 in the entire coke transportation system and providing a basic guarantee for the smooth transportation of coke. By setting a support frame 14 in the civil foundation relative to the position of the three-way chute 4, the three-way chute 4 can be fixed to prevent the three-way chute 4 from being deformed or damaged due to uneven force, ensuring that the connection between the three-way chute 4 and the main chute 1 and the branch chute is tight and stable, and maintaining the integrity and reliability of the entire chute system.

[0076] The main function of the hanging frame 13 is to fix the main chute 1 to the civil foundation. It is firmly connected to the main chute 1 at one end and reliably combined with the civil foundation at the other end through a specific connection method, such as bolt connection, welding or other mechanical connection methods. Thus, a stable support point is provided for the main chute 1, and the weight of the main chute 1 and various forces generated by the flow of materials in the main chute 1 are transmitted to the civil foundation. The stability of the civil foundation is used to ensure that the position of the main chute 1 is fixed, so that it will not move or shake at will during the working process.

[0077] Among them, in the civil foundation, the support frame 14 arranged relative to the position of the three-way chute 4 can be connected to the bottom, side or other key parts of the three-way chute 4, so as to disperse the force exerted on the three-way chute 4 to the civil foundation, thereby ensuring that the three-way chute 4 maintains the correct position and posture in the entire coke conveying system, and maintains good connection and coordination with the main chute 1 and the branch chute, so that the coke can flow smoothly between the chutes, avoiding problems such as poor material transportation and leakage caused by the instability of the three-way chute 4.

[0078] In some possible implementations disclosed in this application, see Figure 1 As shown, an inspection window 15 is provided on the side of the three-way chute 4 away from the civil engineering foundation, and the inspection window 15 is used to observe the flow state of the coke.

[0079] In this embodiment, the operator can observe the flow state of coke in the three-way chute 4 in real time through the inspection window 15, including the flow rate, flow direction, and whether there is blockage, accumulation, etc. of the coke, so as to timely understand the coke transportation situation in the production process and provide an intuitive basis for production control. At the same time, by observing the flow state of coke, it can also assist in judging whether there is a fault in the three-way chute 4 and related equipment. For example, if it is found that the coke flow is not smooth, it may mean that there are problems such as wear, deformation or valve failure inside the chute, which is convenient for maintenance personnel to prepare maintenance tools and accessories in advance and improve maintenance efficiency.

[0080] Among them, the inspection window 15 is a window structure with a certain size and shape opened on the three-way chute 4, which can be closed with a transparent and high-strength material, such as tempered glass, etc., which can not only ensure that the operator can clearly see the internal situation of the chute, but also ensure the sealing and safety of the chute, and prevent the leakage of materials such as coke and the entry of external impurities.

[0081] Specifically, in actual application, the operator can directly observe the flow state of the coke inside the three-way chute 4 through the transparent inspection window 15 with the naked eye or with the help of some auxiliary lighting equipment and observation tools, thereby determining how the coke flows from the main channel to each branch channel, whether there is any flow disorder, blockage or abnormal flow rate, etc.

[0082] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0083] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
