Description

Technical Field

[0001] The present invention belongs to the technical field of coke oven coking, and specifically refers to a coke oven soot collection device. Background Art

[0002] A coke oven is an important device for high-temperature carbonization of coal to produce coke, playing a crucial role in industries such as iron and steel and chemical industries. Modern coke ovens are usually composed of multiple carbonization chambers arranged in parallel, and each carbonization chamber independently performs coal charging, coking, and coke discharging operations. Since a large amount of soot and harmful gases are generated during the coke production process, effective collection and treatment of the soot generated during the coke discharging process are crucial for environmental protection and the health of workers. Currently, coke discharging from a coke oven is an intermittent operation, and each time only a single carbonization chamber is discharged, which makes the design of the soot collection device need to consider both high efficiency and flexibility for a single carbonization chamber. The existing coke oven soot collection technologies mainly have the following deficiencies: Independent negative pressure collection system based on mobile equipment: Some coke ovens install independent negative pressure collection systems on the moving coke pusher and coke guide car. This solution requires a complete waste gas treatment system on the mobile equipment, including a fan, a dust collector, a purification device, etc., resulting in a large system volume, increasing the load and energy consumption of the mobile equipment. If the system on the mobile equipment only undertakes part of the waste gas treatment process, the incompletely purified waste gas needs to be transported to a fixed waste gas treatment device through pipelines. However, due to the frequent movement of the coke pusher and coke guide car, hard pipe connections cannot be achieved, and flexible pipes are difficult to withstand the high temperature and corrosive environment of coke discharging from a coke oven for a long time.

[0003] Independent control system for multiple gas collection hoods: Another solution is to set independent gas collection hoods at the coke discharging ports of each carbonization chamber and connect them to the waste gas treatment system through pipelines. This solution requires multiple gas collection hoods, valves, and independent control systems to ensure that only the gas collection hood corresponding to the carbonization chamber being discharged is opened each time. This makes the system structure complex, difficult to control, and high in maintenance cost. In addition, multiple gas collection hoods occupy a large amount of space, which is not conducive to the operation and maintenance of the coke oven.

[0004] Integral large gas collection hood: Some coke ovens adopt an integral large gas collection hood covering the entire coke discharging area of the coke oven. Although this solution has a simple structure, due to the wide coverage of the gas collection hood and the dispersion of suction, the negative pressure is weakened, and a larger fan power is required to ensure sufficient suction, thereby increasing energy consumption and it is difficult to effectively capture the soot generated during the coke discharging of a single carbonization chamber.

[0005] Movable gas collection hood: Similar to the solution based on mobile equipment, the movable gas collection hood also faces the problem of pipeline connection. In order to ensure reliable connection and durability, hard alloy pipes need to be used, which is contradictory to the mobility of the gas collection hood. Summary of the Invention

[0006] In view of the above situation, the present invention provides a coke oven soot collection device. The movable gas collecting hood of this device can automatically dock and communicate with the smoke exhaust pipe of the corresponding carbonization chamber without a complex control system. When the gas collecting hood moves to the target position, the pipeline is opened, and when the gas collecting hood leaves, the pipeline is closed, and it is bidirectional, compatible with the reciprocating movement of the coke pusher car and the coke guide car, without additional driving and control, and without multiple gas collecting hoods, it can achieve precise and efficient soot collection for a single carbonization chamber, effectively solving the problems of scattered suction and complex pipeline connection in the prior art.

[0007] The technical solution adopted by the present invention is as follows: The present invention provides a coke oven soot collection device, including a coke oven body. Symmetrically fixed on the upper side edge of the coke oven body are position transfer mechanisms for moving between different carbonization chambers. The position transfer mechanisms are respectively located above the two ends of the carbonization chamber of the coke oven body, and the length of the position transfer mechanism covers the entire coke oven body. An L-shaped bracket is provided on the position transfer mechanism, and a two-way docking active opening and closing mechanism is fixed at one end of the L-shaped bracket for actively opening and closing the collection channel. A gas collecting hood is provided below the two-way docking active opening and closing mechanism for collecting soot. The gas collecting hood is located above the outside of the two ends of the carbonization chamber of the coke oven body. A negative pressure pipeline system is provided above the coke oven body for providing negative pressure for collecting soot. A responsive opening and closing mechanism is provided at the end of the negative pressure pipeline system for cooperating with the two-way docking active opening and closing mechanism to realize the opening and closing of the collection channel. The responsive opening and closing mechanism is located directly above the outside of the two ends of each carbonization chamber of the coke oven body. When the two-way docking active opening and closing mechanism reciprocates and translates, it passes directly below the responsive opening and closing mechanism.

[0008] Further, the two-way docking active opening and closing mechanism includes a gas collecting pipe. The gas collecting pipe is fixedly arranged at one end of the L-shaped bracket. The gas collecting pipe is vertically arranged. A first docking ring is coaxially fixed on the outer side of the upper end of the gas collecting pipe. A horizontal rod is arranged inside the upper end of the gas collecting pipe. Both ends of the horizontal rod are fixedly connected to the inner wall of the gas collecting pipe. The upper surface of the horizontal rod is flush with the upper surface of the first docking ring. The horizontal rod passes through the axis of the gas collecting pipe. A central groove parallel to the horizontal rod is opened on the upper surface of the horizontal rod. The central groove passes through the axis of the gas collecting pipe. Side grooves are opened at both ends of the central groove on the upper surface of the first docking ring in communication. The side grooves and the central groove have the same semi-circular cross-section. The outer ends of the side grooves are open. The two side grooves are arranged in parallel. The length direction of the side grooves is parallel to the translation direction of the position transfer mechanism. The acute angle between the central groove and the side groove is 45 degrees.

[0009] Further, the responsive opening and closing mechanism includes a riser pipe, which is vertically and communicatively fixed at the end of the negative pressure pipeline system. Inside the riser pipe near the lower end, a fixed disk is coaxially and fixedly arranged. A follower disk with the same diameter is coaxially and closely arranged under the fixed disk. A clamping shaft is coaxially and fixedly arranged at the center of the upper side of the follower disk. The clamping shaft penetrates upward through the fixed disk and is coaxially clamped and rotatably connected with the fixed disk, so that the fixed disk and the follower disk can rotate relative to each other coaxially. Four first ventilation holes are radially and circumferentially arranged through the fixed disk along the axis. Four second ventilation holes are radially and circumferentially arranged through the follower disk along the axis. The first ventilation holes and the second ventilation holes have the same diameter. The distance between the axis of the first ventilation hole and the axis of the fixed disk is equal to the distance between the axis of the second ventilation hole and the axis of the follower disk. A follower shaft is coaxially fixed under the follower disk. A rotating rod is horizontally fixed on one horizontal side of the follower shaft. A sliding column is vertically fixed at one end of the rotating rod. A second docking ring is coaxially fixed outside the lower end of the riser pipe. Only the downward hemispherical end of the sliding column is located below the second docking ring. Two circular grooves are radially and circumferentially arranged on the lower surface of the second docking ring along the axis. A compression spring is fixed at the bottom of the circular groove. A sealing head is fixed at the lower end of the compression spring. The sealing head is slidably arranged in close contact with the circular groove. When the compression spring is in the initial state, only the downward hemispherical end of the sealing head is located outside the circular groove.

[0010] Further, the riser pipe and the gas collecting pipe have the same pipe diameter. The first docking ring and the second docking ring have the same diameter. When the first docking ring is translated, it can be coaxially docked with the second docking ring. The upper surface of the first docking ring is flush with the lower surface of the second docking ring, so that gas leakage can be avoided when the first docking ring and the second docking ring are coaxially docked. The length of the axis of the first docking ring from the side groove in the direction perpendicular to the side groove is equal to the length of the axis of the sliding column from the axis of the riser pipe. The hemispherical end of the sealing head can be slidably and closely fitted with the side groove. The hemispherical end of the sliding column can be slidably and closely fitted with the side groove and the central groove. When the second docking ring and the first docking ring are coaxially docked, the two sealing heads are respectively located in the two side grooves to block the airflow passing through the side grooves.

[0011] Further, in the initial state, the rotating rod is perpendicular to the translation direction of the position transfer mechanism, and the first ventilation hole is located exactly in the middle of two adjacent second ventilation holes in the horizontal projection. When the first ventilation hole is located exactly in the middle of two adjacent second ventilation holes in the horizontal projection, the first ventilation hole does not intersect with the second ventilation hole, realizing the closing of the airflow channel.

[0012] Furthermore, the position transfer mechanism includes a slide rail, which is fixed on the upper side of the coke oven body. A screw is provided in parallel on the slide rail. Both ends of the screw are engaged and rotatably connected with both ends of the slide rail. A slide table is engaged and slidably provided on the slide rail. The slide table and the screw are connected by a ball screw. When the slide table translates, it travels vertically above different carbonization chambers of the coke oven body. A motor is fixed at one end of the slide rail as the driving part of the position transfer mechanism. The output end of the motor is coaxially and fixedly connected with the screw.

[0013] Furthermore, the negative pressure pipeline system includes a three-level branch pipe, which is symmetrically arranged at the upper edge of the coke oven body, parallel to the slide rail, and fixedly connected to the coke oven body through a supporting structure. The three-level branch pipe is connected and fixedly provided with a four-level branch pipe toward the outside of the coke oven body, and the four-level branch pipe is arranged in an array along the length direction of the three-level branch pipe. The four-level branch pipe is located above the outlets at both ends of the carbonization chamber of the coke oven body, and the ends of the four-level branch pipe are connected to the riser, and one ends of the two three-level branch pipes are connected and fixedly provided with a two-level branch pipe. The middle part of the two-level branch pipe is connected and fixedly provided with a first-level main pipe for connecting to a subsequent smoke treatment system.

[0014] Furthermore, the vertical section of the L-shaped bracket is vertically fixed on the slide.

[0015] Furthermore, the gas collecting hood is sealed and fixedly arranged at the lower end of the gas collecting pipe, and the gas collecting hood can cover the coke pushing and intercepting areas of a single carbonization chamber of the coke oven body to collect the coke pushing and intercepting smoke.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The core of the present invention lies in the ingenious coordination between the responsive opening and closing mechanism and the two-way docking active opening and closing mechanism. The two-way docking active opening and closing mechanism moves with the gas collecting hood. When it reaches the top of the target carbonization chamber, the first docking ring on it is precisely docked with the second docking ring on the corresponding responsive opening and closing mechanism. During this process, the side groove on the first docking ring drives the sliding column, and the sliding column drives the rotating rod to rotate, so that the second air vent on the follower disk is aligned with the first air vent on the fixed disk, and the smoke exhaust channel is opened. When the gas collecting hood leaves, the first docking ring continues to move, and the sliding column drives the rotating rod to continue to rotate, the second air vent is staggered with the first air vent, and the channel is closed. This design realizes precise opening and closing control, and only opens the smoke exhaust channel of the corresponding carbonization chamber when needed, thereby realizing efficient smoke collection, avoiding suction dispersion, and reducing energy consumption. At the same time, since the docking and separation processes are completed automatically, no additional control system is required, which simplifies the control system of the coke oven and improves the degree of automation of the operation.

[0017] (2) The characteristic of two-way docking enables it to be perfectly compatible with the reciprocating motions of coke pushing and coke guiding, further simplifying the device structure. The design of the docking ring and the plug guarantees reliable sealing, minimizing smoke and dust leakage to the greatest extent, which is beneficial to environmental protection and the health of workers. Without installing waste gas treatment equipment on the mobile device also further reduces energy consumption. Compared with the independent control system of multiple gas collection hoods, the present invention only requires one set of gas collection hoods, greatly saving the space above the coke oven and facilitating the operation and maintenance of the coke oven.

When the two-way docking active opening and closing mechanism 4 reciprocates and translates, it passes directly below the responsive opening and closing mechanism 6.

[0033] Among them, the two-way docking active opening and closing mechanism 4 includes a gas collecting pipe 41. The gas collecting pipe 41 is fixedly provided at one end of the L-shaped bracket 3. The gas collecting pipe 41 is vertically arranged. A first docking ring 42 is coaxially fixed on the outer side of the upper end of the gas collecting pipe 41. A horizontal rod 43 is provided inside the upper end of the gas collecting pipe 41. Both ends of the horizontal rod 43 are fixedly connected to the inner wall of the gas collecting pipe 41. The upper surface of the horizontal rod 43 is flush with the upper surface of the first docking ring 42. The horizontal rod 43 passes through the axis of the gas collecting pipe 41. A central groove 44 parallel to the horizontal rod 43 is opened on the upper surface of the horizontal rod 43. The central groove 44 passes through the axis of the gas collecting pipe 41. Side grooves 45 are opened on the upper surface of the first docking ring 42 at both ends of the central groove 44. The cross-sections of the side grooves 45 and the central groove 44 are the same semi-circular shape. The outer ends of the side grooves 45 are open. The two side grooves 45 are arranged in parallel. The length direction of the side grooves 45 is parallel to the translation direction of the position transfer mechanism 2. The acute angle between the central groove 44 and the side groove 45 is 45 degrees.

[0034] Among them, the responsive opening and closing mechanism 6 includes a riser pipe 61. The riser pipe 61 is vertically and communicatively fixed at the end of the negative pressure pipeline system 5. Inside the riser pipe 61 near the lower end, a fixed disk 611 is coaxially and fixedly arranged. A follower disk 62 with the same diameter is coaxially and closely arranged below the fixed disk 611. A clamping shaft 63 is coaxially and fixedly arranged at the center of the upper side of the follower disk 62. The clamping shaft 63 passes upward through the fixed disk 611 and is coaxially clamped and rotatably connected to the fixed disk 611. Four first ventilation holes 612 are radially and arrayedly drilled through the fixed disk 611 along the axis. Four second ventilation holes 621 are radially and arrayedly drilled through the follower disk 62 along the axis. The first ventilation holes 612 and the second ventilation holes 621 have the same diameter. The distance between the axis of the first ventilation hole 612 and the axis of the fixed disk 611 is equal to the distance between the axis of the second ventilation hole 621 and the axis of the follower disk 62. A follower shaft 64 is coaxially and fixedly arranged below the follower disk 62. A rotating rod 65 is horizontally and fixedly arranged on one horizontal side of the follower shaft 64. A sliding column 66 is vertically and fixedly arranged at one end of the rotating rod 65. A second docking ring 67 is coaxially and fixedly arranged outside the lower end of the riser pipe 61. Only the downward hemispherical end of the sliding column 66 is located below the second docking ring 67. Two circular grooves 671 are radially and arrayedly drilled on the lower side surface of the second docking ring 67 along the axis. A compression spring 69 is fixedly arranged at the bottom of the circular groove 671. A plugging head 68 is fixedly arranged at the lower end of the compression spring 69. The plugging head 68 is in close sliding fit with the circular groove 671. When the compression spring 69 is in the initial state, only the downward hemispherical end of the plugging head 68 is located outside the circular groove 671.

[0035] Among them, the riser pipe 61 and the gas collecting pipe 41 have the same pipe diameter. The first docking ring 42 and the second docking ring 67 have the same diameter. When the first docking ring 42 is translated, it can be coaxially docked with the second docking ring 67. The upper side surface of the first docking ring 42 is flush with the lower side surface of the second docking ring 67. The length of the distance from the axis of the first docking ring 42 to the side groove 45 in the direction perpendicular to the side groove 45 is equal to the length of the distance from the axis of the sliding column 66 to the axis of the riser pipe 61. The hemispherical end of the plugging head 68 can be in close sliding fit with the side groove 45. The hemispherical end of the sliding column 66 can be in close sliding fit with the side groove 45 and the central groove 44. When the second docking ring 67 is coaxially docked with the first docking ring 42, the two plugging heads 68 are respectively located in the two side grooves 45.

[0036] Among them, in the initial state, the rotating rod 65 is perpendicular to the translation direction of the position transfer mechanism 2, and the first ventilation hole 612 is located exactly in the middle of two adjacent second ventilation holes 621 in the horizontal projection. When the first ventilation hole 612 is located exactly in the middle of two adjacent second ventilation holes 621 in the horizontal projection, the first ventilation hole 612 does not intersect with the second ventilation holes 621. The position transfer mechanism 2 includes a slide rail 21, which is fixedly arranged on the upper side of the coke oven body 1. A screw rod 22 is arranged in parallel on the slide rail 21. Both ends of the screw rod 22 are clamped and rotatably connected to both ends of the slide rail 21. A slide table 23 is clamped and slidably arranged on the slide rail 21. The slide table 23 is connected to the screw rod 22 by a ball screw connection. When the slide table 23 translates, it vertically passes through above different carbonization chambers of the coke oven body 1. One end of the slide rail 21 is fixedly provided with a motor 24, and the output end of the motor 24 is coaxially and fixedly connected to the screw rod 22.

[0037] Among them, the negative pressure pipeline system 5 includes three - level branch pipes 53, which are symmetrically arranged on the upper edge of the coke oven body 1. The three - level branch pipes 53 are parallel to the slide rail 21. The three - level branch pipes 53 are fixedly connected to the coke oven body 1 through a support structure. The three - level branch pipes 53 are fixedly provided with four - level branch pipes 54 communicating towards the outside of the coke oven body 1. The four - level branch pipes 54 are arranged in an array along the length direction of the three - level branch pipes 53. The four - level branch pipes 54 are located above the two ends of the carbonization chamber of the coke oven body 1. The end of the four - level branch pipe 54 is connected and arranged with the riser pipe 61. One end of the two three - level branch pipes 53 is jointly and fixedly provided with a two - level branch pipe 52, and the middle of the two - level branch pipe 52 is fixedly provided with a first main pipe 51.

[0038] Among them, the vertical section of the L - shaped bracket 3 is vertically and fixedly arranged on the slide table 23. The gas collecting hood 7 is hermetically and fixedly arranged at the lower end of the gas collecting pipe 41. The gas collecting hood 7 can cover the coke pushing and coke guiding areas of a single carbonization chamber of the coke oven body 1.

[0039] During specific use, the position transfer mechanism 2 drives the sliding table 23 to drive the L-shaped bracket 3 to reciprocate along the direction of the three-stage branch pipe 53 through the connection mode of the ball screw, so that the L-shaped bracket 3 drives the bidirectional docking active opening and closing mechanism 4 and the gas collecting hood 7 to pass through each coking chamber. By reasonably setting the structural dimensions, when the sliding table 23 moves to a specific position, the first docking ring 42 can be coaxially docked with one of the second docking rings 67, and the first docking ring 42 and the second docking ring 67 are in close contact. This driving mode of the position transfer mechanism 2 is a well-known prior art in the field and can achieve the same movement path as the coke pusher and the coke guide car, so its specific operating principle will not be elaborated in detail. When the responsive opening and closing mechanism 6 is in the initial state, that is, not affected by the bidirectional docking active opening and closing mechanism 4, the rotating rod 65 is perpendicular to the translation direction of the position transfer mechanism 2 and the first ventilation hole 612 is located exactly in the middle of two adjacent second ventilation holes 621 in the horizontal projection. At this time, the first ventilation hole 612 does not intersect with the second ventilation hole 621. Therefore, the cooperation of the fixed disk 611 and the follower disk 62 blocks the outlet of the riser pipe 61, thereby achieving the overall blockage of the negative pressure pipeline system 5.

[0040] When a coke chamber needs to be coked, the coke pusher and the coke guide car move to both ends of the target coke chamber. The coke pusher pushes the coke in the coke chamber forward, and the coke guide car intercepts and loads the coke from the other side. Before that, the two symmetrically arranged two-way docking active opening and closing mechanisms 4 move from any one direction towards the responsive opening and closing mechanism 6 at the target position at the same time. The cooperation between the two will realize the connection of the riser pipe 61 at the target position. After the negative pressure air flow is turned on, the pusher coke dust and the coke guide dust generated only at the target position can be collected by negative pressure through the negative pressure pipeline system 5 and through the gas collecting hood 7, and the other riser pipes 61 are in a blocked state. Specifically as follows: Since the length of the axis of the first docking ring 42 perpendicular to the side groove 45 in the direction of the side groove 45 is equal to the length of the axis of the sliding column 66 from the axis of the riser pipe 61, and the length direction of the side groove 45 is parallel to the translation direction of the position transfer mechanism 2, and the rotating rod 65 is perpendicular to the translation direction of the position transfer mechanism 2 in the initial state, the rotating rod 65 is perpendicular to the side groove 45. Further, it can be obtained that one of the side grooves 45 will face the sliding column 66. During the process of the first docking ring 42 and the second docking ring 67 approaching each other, the hemispherical end of the sliding column 66 will enter the side groove 45. As it slides in the side groove 45, it will drive the rotating rod 65 and the follower disc 62 to rotate around the axis of the fixed disc 611, and the relative positions of the first ventilation hole 612 and the second ventilation hole 621 will change. When the first docking ring 42 and the second docking ring 67 are coaxially docked, the follower shaft 64 will be located at the center of the central groove 44. Therefore, the rotating rod 65 will be parallel to the central groove 44. Since the acute angle between the central groove 44 and the side groove 45 is 45 degrees, according to the geometric principle, the angle between the rotating rod 65 and the central groove 44 is 45 degrees initially. Now that they are parallel, it means that the rotating rod 65 has rotated 45 degrees. Initially, the angle between the second ventilation hole 621 and the adjacent first ventilation hole 612 is 45 degrees. Therefore, the two will completely coincide at this time, thus realizing the connection between the riser pipe 61 and the gas collecting pipe 41.

[0041] Since the side groove 45 is connected to the outside and there will be air leakage, the plug 68 and the compression spring 69 will play a role. When the second docking ring 67 and the first docking ring 42 are just docked, the first docking ring 42 presses the closest plug 68 into the circular groove 671 to prevent hindering the docking. When the first docking ring 42 and the second docking ring 67 are coaxially docked, the two plugs 68 are respectively located in the two side grooves 45. Under the action of the compression spring 69, the hemispherical ends of the plugs 68 are completely located in the side grooves 45 to realize the air flow blockage, thus realizing complete sealing.

[0042] After the soot is collected, the negative pressure air flow is closed, and the first docking ring 42 is controlled to continue moving forward. According to the positional relationship between the sliding column 66 and the central groove 44, the sliding column 66 moves from one end of the central groove 44 to the other end, and finally enters another side groove 45 and moves out of the other side groove 45. The final rotating rod 65 rotates 180 degrees compared with the initial rotating rod 65. Since the second ventilation holes 621 are set to four, after rotating 180 degrees, the distribution positions of the four second ventilation holes 621 are the same as the initial positions. Therefore, the final fixed disk 611 and the follower disk 62 still block the riser pipe 61, realizing that the riser pipe 61 resumes the blocked state after the first docking ring 42 and the second docking ring 67 are separated. Since the sliding column 66 leaves the corresponding side groove 45 when separated, if it moves in the reverse direction again, the sliding column 66 can still enter the corresponding side groove 45 to realize the re - cooperation of the responsive opening and closing mechanism 6 and the bidirectional docking active opening and closing mechanism 4, so as to realize the bidirectional repeated opening and closing.
