Description

Technical Field

[0001] This utility model belongs to the technical field of graphitization furnace exhaust gas treatment device, and in particular relates to a combined and spliced ​​graphitization furnace exhaust gas treatment device. Background Technology

[0002] During the operation of the graphitization furnace, a large amount of waste gas is generated. This waste gas contains not only C and oxides, S and oxides, but also small amounts of NO, NO2 and other waste gases, as well as graphite powder and other impurities and dust. Direct discharge will seriously pollute the environment.

[0003] Currently, the common treatment method is to first filter the dust and other impurities in the exhaust gas through a filtration device to reduce the burden on subsequent treatment processes and reduce environmental pollution. However, some existing treatment devices are unable to effectively remove the dust and other impurities intercepted on the filter. Over time, a large amount of dust accumulates on the filter, causing its pores to become gradually blocked, increasing the resistance to gas flow, and thus reducing the efficiency of exhaust gas treatment. In order to maintain the operation of the treatment device, the filter components need to be replaced frequently, which not only increases maintenance costs but also increases the complexity and time cost of the treatment process, seriously affecting the overall efficiency and economy of graphitization furnace exhaust gas treatment. Utility Model Content

[0004] The purpose of this invention is to provide a modular, spliced ​​graphitization furnace exhaust gas treatment device. It includes a filtration section. Specifically, while initially filtering the exhaust gas entering the filter tank, the rotation of the rotating shaft drives a vibrating block to rotate. As the vibrating block rotates, its protrusions contact with those on another vibrating block, causing the filter plate to slide on the guide rod and the spring to contract. When the protrusions on the first and second vibrating blocks no longer contact each other, the spring causes the filter plate to return to its original position. This achieves a vibration effect on the filter plate, reducing dust adhesion in the exhaust gas, improving the filter plate's permeability, reducing clogging caused by dust, ensuring filtration efficiency, and solving the problem of existing treatment devices failing to effectively remove dust and other impurities trapped on the filter.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0015] A connecting component is used to connect the dispersion component and the filter tank, thereby introducing the pre-filtered exhaust gas inside the filter tank into the dispersion component.

[0016] A mixing component, which is installed inside a dispersing component, is used to enhance the effect of the dispersing component;

[0017] The system increases the contact area between the exhaust gas after initial filtration inside the filter tank and the water inside the water tank by using dispersion and connection components, thereby improving the adsorption effect on fine dust.

[0018] Furthermore, the filter assembly includes several support blocks fixedly connected to the inner wall of the filter tank, guide rods fixedly connected to the left side of each of the support blocks, springs wound around the outer walls of the guide rods, and filter plates slidably connected to the outer walls of the guide rods.

[0019] In this configuration, one end of several springs is fixedly connected to a corresponding support block, and the other end of several springs is fixedly connected to a filter plate.

[0020] Furthermore, the smoking assembly includes a support frame fixedly connected to the inner wall of the filter canister. A motor is installed on the left side of the support frame. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The right end of the rotating shaft passes through the support frame and is rotatably connected to the support frame. Several fan blades are fixedly connected to the outer wall of the rotating shaft.

[0021] Among them, the rotating shaft is rotatably connected to the support frame through a bearing.

[0022] Furthermore, the vibration assembly includes a vibration block one fixedly connected to the right end of the rotating shaft one, a vibration block two passing through the filter plate, the vibration block two being fixedly connected to the filter plate, and protrusions being fixedly connected to the sides of the vibration block one and the vibration block two that are close to each other.

[0024] Furthermore, the dispersion assembly includes a dispersion box fixedly connected to the inner wall of the water tank, a plurality of sleeves fixedly connected to the bottom of the dispersion box, and a plurality of dispersion holes formed on the outer wall of each of the sleeves; and

[0025] The connecting assembly includes a connecting pipe 1 fixedly connected to the top of the dispersion box, the end of the connecting pipe 1 away from the dispersion box extending to the outside of the water tank and fixedly connected to the water tank, and a connecting pipe 2 fixedly connected to the left end of the filter tank, and flanges fixedly connected to the ends of the connecting pipe 2 and the connecting pipe 1 that are close to each other.

[0029] This utility model has the following beneficial effects:

[0030] 1. By setting up a filtration section, specifically, while initially filtering the exhaust gas entering the filter tank, the rotation of the shaft drives the first vibrating block to rotate. When the first vibrating block rotates, the protrusion on it contacts the protrusion on the second vibrating block, causing the filter plate to slide on the guide rod and the spring to contract. When the protrusions on the first and second vibrating blocks no longer contact each other, the spring drives the filter plate to return to its original position. This achieves the vibration effect on the filter plate, reduces the amount of dust in the exhaust gas adhering to the filter plate, improves the passivity of the filter plate, reduces the clogging problem caused by dust adhesion, and ensures the filtration effect.

[0031] 2. By setting up an adsorption section, specifically, after the waste gas that has undergone initial filtration in the filter tank is introduced into the dispersion box, the outer wall of the sleeve at the bottom of the dispersion box has a dispersion hole. After the waste gas enters the dispersion box through the connecting pipe, it passes through the sleeve and comes into contact with the water in the water tank through the dispersion hole, increasing the gas-liquid contact area. At the same time, the motor drives the rotating shaft and the stirring rod to rotate, so that the waste gas enters the sleeve more evenly, further expanding the gas-liquid contact area, improving the adsorption effect of water on the tiny dust and other impurities in the waste gas, and reducing the dust content in the discharged waste gas.

[0064] The top of the dispersion box 311 is equipped with a sealed protective box to protect the second motor 331 from water corrosion inside the water tank 12. The second rotating shaft 332 is rotatably connected to the dispersion box 311 through a bearing with good sealing performance.

[0065] A specific application of this embodiment is as follows: When using this device, the exhaust gas from the graphitization furnace is first introduced into the filter tank 11 through the air inlet on the right side of the filter tank 11. At this time, the motor 222 is started, and the motor 222 drives the shaft 223 to rotate. When the shaft 223 rotates, it drives the fan blade 224 to rotate, thereby guiding the exhaust gas introduced into the filter tank 11 through the air inlet on the right side of the filter tank 11 to the air outlet on the right side of the filter tank 11. As the exhaust gas flows from the right side of the filter tank 11 to the left side of the filter tank 11, the dust in the exhaust gas will be intercepted by the filter plate 214. The intercepted dust will fall into the collection box 13 at the bottom of the filter tank 11. While the shaft 223 is rotating, it will also drive the vibrating block 231 to rotate. When the vibrating block 231 rotates, the protrusion 233 on the vibrating block 231 will interact with the protrusion 233 on the vibrating block 232. Therefore, when the first vibrating block 231 contacts the protrusion on the second vibrating block 232, it will push the second vibrating block 232 to move. When the second vibrating block 232 moves, it will drive the filter plate 214 to slide on the guide rod 212. When the filter plate 214 moves, it will drive the spring 213 to contract. As the first vibrating block 231 rotates, the first vibrating block 231 and the protrusion 233 on the second vibrating block 232 will no longer be in contact. At this time, the spring 213 will reset, which will push the filter plate 214 to reset, thereby achieving the vibration effect on the filter plate 214. The first vibrating block 231 will achieve continuous cyclic vibration of the filter plate 214 as the rotating shaft 223 continues to rotate, thereby reducing the accumulation of dust in the exhaust gas on the filter plate 214, reducing the possibility of dust and other particles in the exhaust gas clogging the filter plate 214, and maintaining the filtration of the filter plate 214.

[0066] After initial filtration by filter plate 214, the exhaust gas in filter tank 11 enters dispersion box 311 through connecting pipe 322 (connected to the right outlet of filter tank 11) and connecting pipe 321 (connected to connecting pipe 322 via flange 323). Once inside dispersion box 311, the exhaust gas enters sleeve 312 through a slot at the bottom of dispersion box 311 connected to sleeve 312. It then contacts water in water tank 12 through dispersion holes 313 on the outer wall of sleeve 312. The water adsorbs fine dust and other impurities from the exhaust gas and increases the contact area between the exhaust gas and water through the dispersion holes 313, enhancing the adsorption effect of the water. Simultaneously, motor 331 is activated, driving shaft 332 to rotate. The rotation of shaft 332 drives stirring rod 333, ensuring that the exhaust gas enters the sleeves 312 more evenly, guaranteeing uniform gas output from each sleeve 312 and allowing the gas to disperse more evenly in the water. The release is more balanced, thereby expanding the gas-liquid contact area and further improving the adsorption effect. Finally, the adsorbed waste gas rises inside the water tank 12 and is discharged through the exhaust pipe 121 for further treatment. The dust and other impurities adsorbed in the waste gas settle on the inner bottom wall of the water tank 12. Opening the valve 123 allows the sludge deposited inside the water tank 12 to be discharged through the waste discharge pipe 122. In actual use, a detachable sealed top cover can be designed on the top of the water tank 12 to facilitate cleaning of the inside of the water tank 12. At the same time, the filter tank 11 and the collection box 13 in the equipment are connected by bolts, and the connecting pipe 322 on the left end of the filter tank 11 is connected to the connecting pipe 321 on the top of the dispersion box 311 through the flange 323. The dispersion box 311 is installed inside the water tank 12, thus achieving a modular splicing effect for the equipment, allowing for disassembly, individual maintenance or cleaning, and transportation of the equipment.
