[0001] This utility model belongs to the technical field of coke oven flue gas recovery equipment, specifically relating to a coke oven flue gas recovery and treatment device. Background Technology

[0002] A coke oven is an important industrial piece of equipment, mainly used for coal processing. It heats coal to high temperatures, causing it to undergo processes such as pyrolysis, softening, melting, and flow, ultimately decomposing it into useful chemical substances such as coke, coal gas, and coal tar. During combustion, the coke oven produces flue gas and dust. Some components in the coke oven flue gas can be recycled as chemical raw materials, so filtration devices are used to collect them.

[0003] However, the existing coke oven flue gas recovery and treatment devices do not automatically recover the dust inside the adsorption plates used to adsorb dust. The adsorption plates need to be replaced frequently by the staff, and the dust needs to be cleaned and recovered manually. The operation is cumbersome. Moreover, when the adsorption plates are disassembled manually, the flue gas dust cannot be processed, and the coke oven cannot be used during this period, which will affect its normal operation.

[0004] To solve this technical problem, this utility model proposes a coke oven flue gas recovery and treatment device. Utility Model Content

[0005] In view of the problems of the prior art, the purpose of this utility model is to provide a coke oven flue gas recovery and treatment device to solve the problem that the adsorption plate cannot automatically recover the dust inside it and that the adsorption plate needs to be replaced frequently by the staff.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coke oven flue gas recovery and treatment device includes a flue gas box, with ash guide pipes symmetrically connected to both sides of the flue gas box. A first collection hopper is connected to the upper end of the ash guide pipes. A fixed frame is connected to the upper end of the flue gas box and the first collection hopper. A movable plate and a blower hood are slidably connected inside the fixed frame. Two rectangular slots are opened in the movable plate, and an adsorption plate is provided in the rectangular slot. An air guide hose is connected to the blower hood, and a fan is connected to the other end of the air guide hose.

[0009] More preferably, a servo motor is provided on both sides of the fan, and two first threaded rods are provided in the fixed frame. The drive end of the servo motor is connected to the first threaded rods, and a threaded groove is provided in the movable plate. The movable plate is slidably connected in the fixed frame through the first threaded rods.

[0010] More preferably, a second servo motor is provided on both sides of the front end of the fixed frame, and two second threaded rods are provided inside the fixed frame. The drive end of the second servo motor is connected to the second threaded rod, and the second threaded rod is connected to a moving block through a threaded groove. The moving block is connected to the side end of the blower cover, and the blower cover is slidably connected inside the fixed frame through the moving block.

[0011] More preferably, a support frame is provided at the lower end of the adsorption plate, and pressure sensors are connected to the four corners of the upper end of the support frame, with the upper end of the pressure sensors in contact with the adsorption plate.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] (1) In this utility model, by setting an adsorption plate, the dust in the flue gas can be adsorbed and collected in the internal holes. By setting a pressure transmitter, the weight of the adsorption plate can be detected. When the weight of the adsorption plate reaches a certain value, the No. 1 servo motor will drive the moving plate to move, so that the adsorption plate moves to the lower end of the blower hood on its side. At the same time, another adsorption plate moves between the flue gas box and the exhaust pipe to continue adsorbing dust. The fan is started, and it blows air to the adsorption plate at its lower end through the blower hood, so that the dust in the adsorption plate is blown into the No. 1 collection hopper at its lower end, and then slides into the flue gas box. Finally, it enters the collection box through the second collection hopper. Therefore, the dust in the flue gas is collected. The device can continuously adsorb and collect the dust in the flue gas without the need for the staff to frequently replace the adsorption plate, and it will not affect the normal operation of the coke oven.

[0017] (2) In this utility model, by setting a second threaded rod and a moving block, starting the second servo motor will drive the second threaded rod to rotate. The rotation of the second threaded rod and the action of the moving block will drive the blowing hood to move, thereby enabling the adsorption plate at its lower end to be thoroughly blown away. By setting a support frame, the support frame can support the adsorption plate, making it easy to remove the adsorption plate from the moving plate. By setting a frame cover, when it is necessary to replace the adsorption plate, simply move the adsorption plate to the blowing hood at its side end, and then open the frame cover at its upper end to remove it. The operation of replacing the adsorption plate is simple. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0027] like Figure 1-6 As shown, a coke oven flue gas recovery and treatment device includes a flue gas box 1. Flue gas box 1 is symmetrically connected to two sides with ash guide pipes 9. The lower section of the ash guide pipes 9 is inclined, allowing dust to slide off the inner wall of the ash guide pipes 9. A first collection hopper 8 is connected to the upper end of the ash guide pipes 9. A fixed frame 2 is connected to the upper end of the flue gas box 1 and the first collection hopper 8. A movable plate 3 and a blower hood 6 are slidably connected inside the fixed frame 2. Two rectangular slots are opened inside the movable plate 3, and adsorption plates 4 are installed inside the rectangular slots to adsorb dust in the flue gas. The blower hood 6 is connected to a flexible air guide hose 19. The other end of the flexible air guide hose 19 is connected to a fan 7. When the fan 7 is started, air is supplied to the blower hood 6 through the flexible air guide hose 19. The flexible air guide hose 19 can be bent and deformed, and can still supply air to the adsorption plates 4 when the blower hood 6 moves.

[0028] The lower end of the flue gas box 1 is connected to a second collection hopper 10, and the lower end of the second collection hopper 10 is connected to a collection box 11. The rear end of the flue gas box 1 is connected to a flue gas connecting pipe 12, which is connected to the exhaust pipe of the coke oven. The flue gas generated by the coke oven will enter the flue gas box 1 through the flue gas connecting pipe 12. An exhaust pipe 20 is set inside the fixed frame 2, which is directly opposite the flue gas box 1. The flue gas that has been adsorbed and filtered will be discharged from the exhaust pipe 20. The upper surface of the movable plate 3 is connected to the lower end of the exhaust pipe 20. A sealing strip is set at the connection to prevent the flue gas from overflowing from the connection between the two. Frame covers 21 are set on both sides of the top of the fixed frame 2. A sealing strip is set at the connection between the frame cover 21 and the fixed frame 2. A handle is set at the upper end of the frame cover 21 for easy opening of the frame cover 21.

[0029] A servo motor 14 is installed on both sides of the fan 7. Two threaded rods 13 are installed inside the fixed frame 2. The drive end of the servo motor 14 is connected to the threaded rod 13. The movable plate 3 has a threaded groove. The movable plate 3 is connected to the fixed frame 2 through the threaded rod 13. When the servo motor 14 is started, it will drive the threaded rod 13 to rotate. The rotation of the threaded rod 13 interacts with the movable plate 3, which will enable the movable plate 3 to move within the fixed frame 2, thereby realizing the movement of the adsorption plate 4.

[0030] The front sides of the fixed frame 2 are equipped with two servo motors 18. Two second threaded rods 16 are installed inside the fixed frame 2. The drive end of the second servo motor 18 is connected to the second threaded rod 16. The second threaded rod 16 is connected to a moving block 17 through a threaded groove. The moving block 17 is connected to the side of the blower hood 6. The rotation of the second threaded rod 16 and the action of the moving block 17 will enable the moving block 17 to drive the blower hood 6 to move, thereby enabling a full blowing of the adsorption plate 4 at its lower end, blowing off the dust inside the adsorption plate 4.

[0031] The second threaded rod 16 is located above the first threaded rod 13, and the blower shroud 6 is located above the adsorption plate 4.

[0032] The lower end of the adsorption plate 4 is provided with a support frame 15, which is used to support the adsorption plate 4. Pressure sensors 5 are connected to the four corners of the upper end of the support frame 15. The upper end of the pressure sensor 5 is in contact with the adsorption plate 4. The pressure sensor 5 can detect the weight of the adsorption plate 4. Since the dust particles have weight, when the adsorption plate 4 adsorbs dust, its weight will increase, thereby calculating the amount of dust adsorbed by the adsorption plate 4 and preventing the adsorption plate 4 from becoming oversaturated with dust.

[0033] In use, the flue gas connecting pipe 12 is connected to the exhaust pipe of the coke oven. The flue gas generated by the coke oven enters the flue gas box 1 through the flue gas connecting pipe 12 and then flows to the exhaust pipe 20. When the flue gas passes through the adsorption plate 4, the dust is adsorbed. When the data monitored by the pressure sensor 5 reaches a certain value, the first servo motor 13 will drive the moving plate 3 to move, so that the adsorption plate 4 moves to the lower end of the blower hood 6 on its side. At the same time, the other adsorption plate 4 moves between the flue gas box 1 and the exhaust pipe 20 to continue adsorbing dust, realizing the switching of adsorption between the two adsorption plates 4. The fan 7 is started, and air is blown to the adsorption plate 4 at its lower end through the blower hood 6. The second servo motor 1... The 8-driven moving block 17 moves, causing the blowing hood 6 to cover the entire adsorption plate 4, blowing the dust in the adsorption plate 4 into the first collection hopper 8 at its lower end, then sliding into the flue gas box 1, and finally entering the collection box 11 through the second collection hopper 10, thus completing the collection of dust in the flue gas. This device can continuously adsorb and collect dust in the flue gas without the need for frequent replacement of the adsorption plate 4 by the staff, and will not affect the normal operation of the coke oven. When it is necessary to replace the adsorption plate 4, simply move the adsorption plate 4 under the blowing hood 6 at its side end, and then open the frame cover 21 at its upper end to remove it, making the replacement of the adsorption plate 4 more convenient.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
