Description

Technical Field

[0001] This utility model relates to the technical field of graphitization furnace exhaust gas treatment equipment, specifically to an exhaust gas treatment device for a graphitization furnace. Background Technology

[0002] A graphitization furnace is a core industrial equipment that uses high-temperature heat treatment to convert carbon materials into high-purity graphite materials. It is widely used in new energy, metallurgy, aerospace and other fields. However, graphitization furnaces produce exhaust gas during operation, which contains pollutants. Direct emission of this gas will pollute the environment. Therefore, exhaust gas treatment devices are used to filter and purify the exhaust gas produced during graphitization furnace production to ensure that the emitted exhaust gas meets emission standards.

[0003] Currently, most graphitization furnace exhaust gas treatment devices typically use filter adsorption plates to adsorb and filter impurities in the exhaust gas. However, the activated carbon in the filter adsorption plates decreases over time, and since these plates are usually installed inside the equipment, operators cannot immediately detect the deterioration in their adsorption capacity. This can lead to a significant amount of exhaust gas failing to meet emission standards, causing environmental pollution. Furthermore, traditional installations often rely on multiple bolts for fixing, making it time-consuming to replace the filter adsorption plates and affecting the equipment's ability to treat exhaust gas, thus rendering it inconvenient to use. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tail gas treatment device for a graphitization furnace, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tail gas treatment device for a graphitization furnace, comprising: a treatment box, a replacement slot provided on one side of the treatment box, and connecting pipes 1 fixedly connected to both sides of the inner wall of the replacement slot; a motor installed on one side of the treatment box, the output end of the motor connected to a rotating rod via a coupling; connecting pipes 2 symmetrically arranged on both sides of the outer surface of the rotating rod; filter adsorption plates detachably installed inside both connecting pipes 2; one connecting pipe 2 being located between the two connecting pipes 1; an outlet pipe fixedly connected to the outlet of the treatment box; and a gas detector installed on one side of the outlet pipe.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] This utility model provides a technical solution: such as Figure 1 - Figure 5As shown, in this embodiment, a tail gas treatment device for a graphitization furnace includes: a treatment box 1, a replacement slot 2 is provided on one side of the treatment box 1, and connecting pipes 23 are fixedly connected to both sides of the inner wall of the replacement slot 2; a motor 21 is installed on one side of the treatment box 1, and the output end of the motor 21 is connected to a rotating rod 22 through a shaft coupling; connecting pipes 25 are symmetrically arranged on both sides of the outer surface of the rotating rod 22; filter adsorption plates 26 are detachably installed inside the two connecting pipes 25; one connecting pipe 25 is located between the two connecting pipes 23; the gas outlet of the treatment box 1 is fixedly connected to a gas outlet pipe 11, and a gas detector 24 is installed on one side of the gas outlet pipe 11.

[0020] The gas detector 24 monitors the treated gas in the treatment chamber 1 in real time. When the gas fails to meet emission standards, a signal is transmitted to the controller 5, alerting the operator. The operator then uses a tool to rotate the two threaded rings 4 to release the restriction on the connecting pipe 25 in the replacement slot 2. By turning on the motor 21 and rotating the rotating rod 22 180 degrees, the two connecting pipes 25 are swapped. The operator then uses a tool to rotate the connecting pipe 25 in the replacement slot 2 to replace the filter adsorption plate 26 inside the equipment. This structural design allows for immediate detection of when the filter adsorption plate 26 needs replacement, preventing the discharge of excessive exhaust gas that does not meet emission standards. Furthermore, the rapid replacement of the filter adsorption plate 26 improves the equipment's ability to treat exhaust gas.

[0021] It should be noted that: the filter adsorption plate 26 can be installed in the connecting pipe 25 by bolts or clips; when removing the filter adsorption plate 26 from the connecting pipe 25, after replacing it with a new filter adsorption plate 26, the operator can disassemble it; the gas detector 24 detects the composition and concentration of the gas; the gas detector 24 can be of catalytic combustion type, electrochemical type, infrared absorption type, etc.; the outlet end of the gas outlet pipe 11 is equipped with an electric valve, which closes when the gas detector 24 detects that the gas does not meet the emission standards.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, an air extraction pipe 31 is fixedly connected to one side of the upper end of the processing box 1. One end of the air extraction pipe 31 is fixedly connected to the collection box 3, and the other end of the air extraction pipe 31 extends into the replacement tank 2. The air outlet of the collection box 3 is fixedly connected to the air inlet of the processing box 1 through a connecting pipe. A second fan 34 is installed on one side of the inside of the air extraction pipe 31, a solenoid valve 32 is installed on one side of the air extraction pipe 31, and a first fan 33 is installed on the inner wall of the connecting pipe.

[0023] Through the structural design of the collection box 3, the exhaust pipe 31, the solenoid valve 32, and the second fan 34, when the staff replaces the filter adsorption plate 26 in the treatment box 1, the first fan 33 is turned off to reduce the amount of exhaust gas entering the treatment box 1, and the second fan 34 and the solenoid valve 32 are turned on to adsorb the gas entering the treatment box 1 into the collection box 3 for storage. This structural design avoids the staff from inhaling a large amount of exhaust gas when replacing the filter adsorption plate 26, ensuring the health of the staff, and also prevents a large amount of exhaust gas from escaping into the air and causing environmental pollution.

[0024] like Figure 3 and Figure 4 As shown, both ends of the connecting pipe 25 are threaded with threaded rings 4, and rubber rings 41 are fixedly connected to the inner walls of the two threaded rings 4. One end of the two connecting pipes 23 is inside the two threaded rings 4 respectively. By rotating the threaded rings 4, the threaded rings 4 are connected to the connecting pipes 23, and the rubber rings 41 are attached to one end of the connecting pipes 23, thereby sealing the gap between the connecting pipe 25 and the rubber rings 41 to prevent the leakage of untreated exhaust gas.

[0025] like Figure 1 and Figure 2 As shown, a water tank 12 is installed at the top of the treatment box 1, and a water mist generator 15 is installed at the top inside the treatment box 1. The input end of the water mist generator 15 is fixedly connected to the output end of the water tank 12, and the output end of the water mist generator 15 is fixedly connected to a spray frame 16. By turning on the water mist generator 15, the water in the water tank 12 is atomized and sprayed out through the spray frame 16 to cool down the temperature of the exhaust gas entering the treatment box 1. At the same time, the waste residue contained in the exhaust gas can fall into the treatment box 1 after being exposed to water for preliminary waste residue filtration.

[0026] like Figure 1 As shown, a water outlet pipe 13 is fixedly connected to the other side of the treatment tank 1, and a valve 14 is installed on one side of the water outlet pipe 13; by turning the valve 14, the water at the bottom of the treatment tank 1 is discharged.

[0027] like Figure 1 As shown, a controller 5 is installed on the other side of the treatment tank 1 and above the outlet pipe 13; the controller 5 is used to control the equipment on the treatment tank 1 and the collection tank 3 to cooperate with each other and to remind the staff that the filter adsorption plate 26 needs to be replaced.

[0028] This utility model provides a tail gas treatment device for a graphitization furnace, the specific working principle of which is as follows: When treating the exhaust gas generated by the graphitization furnace, firstly, fan 33 is turned on to discharge the exhaust gas through collection box 3 into treatment box 1. Then, water mist generator 15 is turned on to atomize water in water tank 12 and spray it out through spray rack 16, cooling the exhaust gas entering treatment box 1. Simultaneously, the waste residue contained in the exhaust gas falls into treatment box 1 upon contact with water for preliminary filtration. After preliminary filtration, the exhaust gas passes through filter adsorption plate 26 in replacement tank 2. The filter adsorption plate 26 adsorbs and filters the exhaust gas, and the treated exhaust gas is discharged from outlet pipe 11. Gas detector 24 monitors the exhaust gas in real time. With prolonged use, the activated carbon in filter adsorption plate 26 decreases, and its filtration and adsorption effect deteriorates. Gas detector 24 will detect that the exhaust gas treatment does not meet the emission standards. Gas detector 24 will transmit a signal to controller 5 and remind the staff. At the same time, fan 1 33 will be turned off to reduce the exhaust gas entering the treatment box 1. Fan 2 34 and solenoid valve 32 will be turned on to adsorb the gas entering the treatment box 1 and store it in collection box 3. The staff will use tools to rotate the two threaded rings 4 to release the restriction of the connecting pipe 25 in the replacement slot 2. Then, the motor 21 will be turned on and the rotating rod 22 will be rotated 180 degrees to exchange the positions of the two connecting pipes 25. The staff will then use tools to rotate the connecting pipe 25 in the replacement slot 2 to replace the filter adsorption plate 26 in the equipment. After the replacement is completed, the above operation will be repeated to treat the exhaust gas.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
