Description

Technical Field

[0001] This invention belongs to the field of high-efficiency activated carbon deodorization technology, specifically an activated carbon deodorization device for wastewater treatment. Background Technology

[0002] Wastewater treatment is a process that removes pollutants from urban sewage and industrial wastewater through a series of physical, chemical, and biological methods, purifying them to meet discharge standards and enabling reuse. During the treatment process, especially in the pretreatment and sludge treatment stages, malodorous gases containing components such as hydrogen sulfide and ammonia are generated. Activated carbon deodorization devices are a highly efficient back-end gas purification equipment. They concentrate these collected odorous gases through a pipeline system and utilize the strong adsorption capacity of the activated carbon filled inside the device to capture and remove malodorous substances. This is one of the key links in ensuring the environmentally friendly operation of wastewater treatment plants.

[0003] The activated carbon deodorization device works through adsorption. It is filled with highly efficient activated carbon with an extremely well-developed pore structure and a huge specific surface area. When malodorous gas penetrates the activated carbon bed under the action of a fan, odor molecules in the gas, such as hydrogen sulfide, mercaptans, and volatile organic compounds, are captured and firmly attached to the surface of the abundant micropores of the activated carbon through chemical bonding. This achieves the separation of gas and pollutants, and the purified clean air is discharged from the other end of the device, thus achieving the purpose of eliminating malodor and purifying the air.

[0004] During wastewater treatment, a large amount of odorous gases are generated, which can easily pollute the environment. To address this pollution problem, traditional wastewater treatment systems employ activated carbon deodorization devices. The core of these devices is a deodorization channel equipped with high-efficiency activated carbon, which filters and purifies the passing odorous gases. Activated carbon, with its numerous micropores and large specific surface area, effectively adsorbs pollutants from the air, making it a commonly used deodorizing material. However, wastewater treatment is a long-term, continuous process, generating a large volume of various odorous gases. Over time, the activated carbon in traditional deodorization devices easily reaches saturation, reducing its adsorption capacity and consequently lowering purification efficiency. Frequent shutdowns to replace activated carbon in an effort to improve purification efficiency would significantly reduce the equipment's efficiency, thus impacting the overall wastewater treatment process.

[0005] Therefore, the present invention provides an activated carbon deodorization device for wastewater treatment. Summary of the Invention

[0008] Preferably, a fixed frame is fixedly connected to the center of the deodorization channel inside the deodorization box; two guide rods are fixedly connected to the fixed frame; a sliding frame is slidably connected to the guide rods, the activated carbon plate is fixedly connected to the sliding frame, and the sliding frame can be fixed to the fixed frame by screws.

[0009] Preferably, a guide plate is fixedly connected to the partition plate; the side of the guide plate away from the partition plate is set as an arc-shaped inclined surface.

[0010] Preferably, a fixed rod is fixedly connected to the center of the deodorization channel inside the deodorization box; a rotating rod is rotatably connected to the fixed rod; a baffle plate is fixedly connected to the rotating rod; a mating plate is fixedly connected to the inside of the deodorization box near the baffle plate; and a transmission assembly is provided inside the deodorization box to drive the baffle plate to rotate.

[0011] Preferably, the transmission assembly includes a toothed plate, an elastic element, and a toothed ring; the toothed plate is slidably connected inside the deodorizing chamber near the guide plate; the elastic element is fixed between the toothed plate and the inner wall of the deodorizing chamber; the toothed ring is fixed to the rotating rod, and the toothed plate can mesh with the toothed ring.

[0012] Preferably, an exhaust fan is fixedly connected inside the air intake pipe; an air-gathering ring plate is fixedly connected to the deodorizing casing inside the air intake pipe.

[0013] Preferably, a guide plate is fixed inside the deodorizing chamber near the air inlet pipe. The cross-section of the guide plate near the air inlet pipe is triangular, and the upper and lower surfaces of the other end of the guide plate are both arc-shaped.

[0014] Preferably, multiple guide tubes are fixed to both the upper and lower surfaces of the guide plate, with one end of the guide tube near the air intake pipe being flared and the other end of the guide tube being inclined.

[0015] Preferably, an adsorption plate is fixedly attached to the arc-shaped inclined surface of the guide plate; and multiple activated carbon fiber felts are fixedly attached to the adsorption plate.

[0016] Preferably, the diameter of the air inlet near the air inlet pipe on the deodorizing casing is smaller than the diameter of the air inlet near the air outlet pipe; the activated carbon plate is made of high-quality coal-based honeycomb activated carbon.

[0017] The beneficial effects of this invention are as follows: 1. The activated carbon deodorization device in the wastewater treatment process of this invention features two different purification modes: an alternating purification mode and a high-efficiency purification mode. In the alternating purification mode, a large amount of odorous gas is introduced into the deodorization chamber through the inlet pipe. At this time, an electric slider drives a partition plate to slide on the guide rail, blocking the center of one deodorization channel while the other deodorization channel remains open. After entering the deodorization chamber, the odorous gas passes through the open deodorization channel and is purified at the activated carbon plate. The purified gas is then discharged from the outlet pipe, while the blocked deodorization channel remains in a resting state to allow the activated carbon plate inside to regain its adsorption capacity. When the activated carbon plate in the working deodorization channel becomes saturated, the electric slider drives the partition plate to slide, switching the working states of the two deodorization channels. The system employs two alternating purification modes to ensure continuous and efficient operation of the deodorization device. In alternating purification mode, when the activated carbon plates in the deodorization channels become saturated and need replacement, the saturated deodorization channel is closed, and the assembly plate is simply removed and the activated carbon plate replaced, enabling efficient continuous processing without shutting down the machine. In high-efficiency purification mode, two electric sliders simultaneously drive the corresponding partition plates, opening both deodorization channels. A large amount of odorous gas enters the deodorization chamber through the inlet pipe and passes through both channels simultaneously. Upon reaching the two activated carbon plates, the odorous gas is purified simultaneously, and the purified gas is discharged together through the outlet pipe. This mode can efficiently purify large amounts of odorous gas in a short time, meeting urgent and high-load deodorization needs, effectively handling large volumes of odorous gas, and improving purification efficiency.

[0018] 2. The activated carbon deodorization device in the wastewater treatment process described in this invention uses an electric slider to drive a partition plate and a guide plate to slide. The guide plate can compress and push the toothed plate to slide. The elastic element is compressed and contracts under force. During the sliding of the toothed plate, the toothed structure on it meshes with the toothed structure of the toothed ring, causing the toothed ring to rotate. Since the toothed ring is fixed to the rotating rod, the rotation of the toothed ring will synchronously drive the rotating rod to rotate, thereby causing the barrier plate to rotate as well. When the barrier plate rotates to fit with the mating plate, the sealing action at the saturated activated carbon plate is completed. At this time, the operator can open the assembly plate according to the established procedure to safely and efficiently replace the adsorbed saturated activated carbon plate. After the new activated carbon plate is installed, the electric slider drives the partition plate to slide and reset. The guide plate then moves away from the toothed plate. After the elastic element loses the compressive force, it returns to its original state. The toothed plate resets under the action of the elastic element, the barrier plate leaves the mating plate, and the deodorization channel is restored to an unobstructed state. The entire device continues to operate stably. This transmission component design ensures the smooth operation of replacing activated carbon without stopping the machine, greatly improving the working efficiency and continuity of the deodorization device.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Wastewater treatment is a process that removes pollutants, organic matter, and harmful microorganisms from domestic sewage and industrial wastewater through a series of physical, biological, and chemical processes, purifying them to meet the standards for safe discharge and reuse. During the treatment process, especially in the pretreatment and sludge treatment stages, malodorous gases containing components such as hydrogen sulfide and ammonia will be generated. Activated carbon is a carbon material that has undergone special activation treatment and has an extremely high specific surface area and well-developed pore structure. Its maze-like micropores can act like a sponge, efficiently adsorbing and locking in impurities and odor molecules in gases and liquids. Traditional deodorization devices with high-efficiency activated carbon typically consist of a sealed tower filled with granular or honeycomb activated carbon beds. An internal deodorization channel is built-in to purify odors generated during wastewater treatment. During operation, the collected odors are driven by a fan and enter from one end of the tower, forced to pass evenly through the entire high-efficiency activated carbon adsorption layer. Pollutants in the odors are captured by the pores as they flow through the carbon bed, and the purified gas is discharged from the other end. This is a simple and widely used physical adsorption deodorization device.

[0024] In order to better purify the odor generated during the sewage treatment process, such as Figures 1 to 4 , Figure 6As shown in the embodiment of the present invention, an activated carbon deodorization device in a wastewater treatment process includes a deodorization housing 1; an air inlet pipe 11 and an air outlet pipe 12 are respectively fixedly connected to the air vents at both ends of the deodorization housing 1; two deodorization channels are opened inside the deodorization housing 1, and an assembly plate 13 is fixedly connected to the center of one side of the deodorization housing 1 near the center of the deodorization channel by bolts; an activated carbon plate 14 is arranged at the center of the deodorization channel inside the deodorization housing 1; two guide rail frames 15 are fixedly connected to each other inside the deodorization housing 1; a partition plate 16 is slidably connected to the guide rail frame 15 by an electric slider, and the partition plate 16 can block the center of the deodorization channel; in the field of activated carbon, the high efficiency of activated carbon on the activated carbon plate 14 lies in its design that trades space for time and structure for performance. First, it has an amazing microscopic storage capacity, one gram of high-quality activated carbon... With a specific surface area exceeding that of a standard football field, it possesses a sponge-like, highly developed nanoscale pore network. When airflow passes through, the massive pores provide a huge adhesion surface and storage space for odor molecules, enabling them to be efficiently captured in an extremely short contact, achieving high-speed and high-capacity physical adsorption. Secondly, its efficiency can be qualitatively improved through chemical customization. By impregnating the surface of the highly efficient activated carbon with specific chemicals, it transforms from passive capture to active attack. For example, for hydrogen sulfide odor, a major odor in wastewater treatment, the impregnated carbon can undergo an irreversible chemical reaction with it, converting it into stable salts for fixation. This dual mechanism of physical adsorption and chemical transformation not only significantly improves the removal efficiency and adsorption capacity of targeted odors but also enhances its working stability in complex environments such as humidity, thereby achieving a deep, long-lasting, and reliable deodorization effect. In the process of sewage treatment, especially in the pretreatment and sludge treatment stages, malodorous gases containing components such as hydrogen sulfide and ammonia are generated. When using high-efficiency activated carbon to purify and deodorize the large amount of odorous gases, the deodorization box 1 is used as the main body of the activated carbon deodorization device. The air inlet pipe 11 is connected to the odor delivery pipe, and the air outlet pipe 12 is used to discharge the purified gas. The activated carbon plate 14 is high-efficiency activated carbon. First, open the two assembly plates 13 and put the two activated carbon plates 14 into the center of the two deodorization channels respectively. This activated carbon deodorization device has two purification modes: alternating purification mode and high-efficiency purification mode. In alternating purification mode, a large amount of odorous gas is introduced into the deodorizing chamber 1 through the air inlet pipe 11. At this time, an electric slider drives the partition plate 16 to slide on the guide rail 15. The partition plate 16 blocks the center of one deodorizing channel, while the other deodorizing channel is open. After the odorous gas enters the deodorizing chamber 1, it passes through the open deodorizing channel and is purified at the activated carbon plate 14. The purified gas is discharged from the air outlet pipe 12, while the blocked deodorizing channel is in a resting state so that the activated carbon plate 14 inside can restore its adsorption capacity. When the activated carbon plate 14 in the working deodorizing channel is saturated, the electric slider drives the partition plate 16 to slide, exchanging the working state of the two deodorizing channels to achieve alternating purification and ensure the continuous and efficient operation of the deodorizing device. Meanwhile, in the alternating purification mode, when the activated carbon plate 14 in the deodorization channel becomes saturated and needs to be replaced, the deodorization channel with the saturated activated carbon plate 14 is closed, and the assembly plate 13 is removed and the activated carbon plate 14 is replaced directly, which can achieve efficient continuous processing without stopping the machine. In the high-efficiency purification mode, the two electric sliders simultaneously drive the corresponding partition plates 16 to slide, so that both deodorization channels are open. At this time, a large amount of odorous gas enters the deodorization chamber 1 from the air inlet pipe 11 and passes through the two deodorization channels at the same time. After the odorous gas reaches the two activated carbon plates 14, it is purified at the same time. The purified gas is discharged from the air outlet pipe 12 together. This mode can efficiently purify a large amount of odorous gas in a short time, meet the needs of emergency and high-load deodorization, efficiently handle a large amount of odorous gas, and improve the purification efficiency.

[0025] A fixing frame 2 is fixedly connected to the center of the deodorization channel inside the deodorization housing 1; two guide rods 21 are fixedly connected to the fixing frame 2; a sliding frame 22 is slidably connected to the guide rods 21, and the activated carbon plate 14 is fixedly connected to the sliding frame 22, and the sliding frame 22 can be fixed to the fixing frame 2 with screws; when assembling the two activated carbon plates 14, the two fixing frames 2 are fixed relative to each other at the center of the two deodorization channels inside the deodorization housing 1. After opening the two assembly plates 13, the activated carbon plate 14 is first fixed to the sliding frame 22, then the round hole on the sliding frame 22 is aligned with the two guide rods 21, the sliding frame 22 is inserted into the guide rods 21, and then one end of the sliding frame 22 is fixed with screws. On the fixed frame 2, the activated carbon plate 14 is now securely installed in the center of the deodorization channel. This installation method is not only structurally stable, but also facilitates subsequent disassembly and replacement. When the activated carbon plate 14 needs to be replaced, simply unscrew the screws and slide the sliding frame 22 off the guide rod 21 to easily remove the old activated carbon plate 14. Then, install the new activated carbon plate 14 following the same steps. The entire process does not require large-scale disassembly of the entire deodorization device, saving maintenance time and costs. At the same time, the cooperative design of the fixed frame 2, guide rod 21, and sliding frame 22 also ensures the precise positioning of the activated carbon plate 14 in the deodorization channel, allowing the odor to pass through the activated carbon plate 14 evenly, thus improving the deodorization efficiency.

[0026] like Figures 1 to 3 As shown, a guide plate 3 is fixedly connected to the partition plate 16; the side of the guide plate 3 away from the partition plate 16 is set as an arc-shaped inclined surface; when the odor enters the deodorizing chamber 1 for purification, one activated carbon plate 14 in the alternating purification mode of the two deodorizing channels can meet the high-efficiency deodorization. As the electric slider drives the partition plate 16 to slide and block one deodorizing channel, the guide plate 3 on the partition plate 16 also slides accordingly. After the partition plate 16 blocks one deodorizing channel, the arc-shaped inclined surface of the guide plate 3 can guide the passing odor to the activated carbon plate 14 of the other deodorizing channel, so that the odor can pass through the working deodorizing channel more concentratedly and smoothly, avoiding the odor from generating eddies and stagnating at the blockage point, thereby improving the purification efficiency and effect of the odor. At the same time, the arc-shaped inclined surface design of the guide plate 3 also reduces the resistance when the odor passes through, making the entire activated carbon deodorizing device more efficient in operation.

[0027] A fixed rod 4 is fixedly connected to the center of the deodorization channel inside the deodorization chamber 1; a rotating rod 41 is rotatably connected to the fixed rod 4; a baffle plate 42 is fixedly connected to the rotating rod 41; a mating plate 43 is fixedly connected to the inside of the deodorization chamber 1 near the baffle plate 42; a transmission assembly is provided inside the deodorization chamber 1, which is used to drive the baffle plate 42 to rotate; when the saturated activated carbon plate 14 is replaced, the electric slider drives the partition plate 16 to slide, and the guide plate 3 simultaneously approaches the transmission assembly and squeezes and pushes it. The pushed transmission assembly simultaneously drives the rotating rod 41 on the fixed rod 4 to rotate, so that the baffle plate 42 rotates and fits against the mating plate 43. The baffle plate 42, together with the mating plate 43 and the partition plate 16, removes the saturated activated carbon plate 14. When the activated carbon plate 14 is blocked, the operator can open the assembly plate 13, remove the saturated activated carbon plate 14 from the sliding frame 22, and replace it with a new activated carbon plate 14. After replacing the activated carbon plate 14, the electric slider is used to drive the partition plate 16 to slide back to its original position. The guide plate 3 moves away from the transmission component, and the transmission component is no longer squeezed and resets itself. The barrier plate 42 moves away from the mating plate 43 and returns to its initial state, so that the deodorization channel is unblocked again. The entire replacement process does not require stopping the flow of odor, realizing the replacement of activated carbon without stopping the machine. This improves the working efficiency and continuity of the deodorization device, reduces the odor treatment interruption time caused by stopping the machine to replace activated carbon, and ensures the stability and reliability of odor treatment in the sewage treatment process.

[0028] The transmission assembly includes a toothed plate 5, an elastic element 51, and a toothed ring 52. The toothed plate 5 is slidably connected inside the deodorizing housing 1 near the guide plate 3. The elastic element 51 is fixed between the toothed plate 5 and the inner wall of the deodorizing housing 1. The toothed ring 52 is fixed to the rotating rod 41, and the toothed plate 5 can mesh with the toothed ring 52. When the electric slider drives the partition plate 16 and the guide plate 3 to slide, the guide plate 3 can squeeze and push the toothed plate 5 to slide. The elastic element 51 is squeezed and compressed under force. During the sliding process of the toothed plate 5, its toothed structure meshes with the toothed structure of the toothed ring 52, causing the toothed ring 52 to rotate. Since the toothed ring 52 is fixed to the rotating rod 41, the rotation of the toothed ring 52 will synchronously drive the rotating rod 41 to rotate, thereby causing the barrier plate 4 to rotate. 2. As the plate rotates, when the baffle plate 42 rotates to fit with the mating plate 43, the sealing action at the saturated activated carbon plate 14 is completed. At this time, the staff can open the assembly plate 13 according to the established procedure to safely and efficiently replace the saturated activated carbon plate 14. After the new activated carbon plate 14 is installed, the electric slider drives the partition plate 16 to slide and reset. The guide plate 3 then moves away from the toothed plate 5. After the elastic element 51 loses the squeezing force, it returns to its original state. The toothed plate 5 resets under the action of the elastic element 51, the baffle plate 42 leaves the mating plate 43, and the deodorization channel is restored to a smooth state. The entire device continues to operate stably. The design of this transmission component ensures the smooth operation of replacing activated carbon without stopping the machine, which greatly improves the working efficiency and continuity of the deodorization device.

[0029] like Figures 1 to 3 As shown, an exhaust fan 6 is fixedly connected inside the air inlet pipe 11; a concentrating ring plate 61 is fixedly connected to the deodorizing housing 1 inside the air inlet pipe 11; when odorous gas is introduced into the deodorizing housing 1, the exhaust fan 6, fixed inside the air inlet pipe 11, rotates to extract the odorous gas, and the concentrating ring plate 61, fixed at one end of the deodorizing housing 1, guides the odorous gas. Under the synergistic action of the exhaust fan 6 and the concentrating ring plate 61, the odorous gas can enter the deodorizing housing 1 with a stable and uniform flow rate, avoiding localized cleanliness caused by uneven odorous gas flow. The problem of excessive pressure and insufficient purification provides a good airflow foundation for subsequent efficient deodorization. At the same time, the stable operation of the exhaust fan 6 ensures the stability of the air intake of the entire activated carbon deodorization device during continuous operation, reducing the possibility of device failure and decreased purification effect caused by air intake fluctuations, and further improving the reliability and stability of the device. Moreover, the guiding design of the air-gathering ring plate 61 allows the odor to enter the deodorization channel more accurately and make full contact with the activated carbon plate 14, improving the odor purification efficiency.

[0030] like Figures 1 to 3 , Figure 5 As shown, a guide plate 7 is fixedly connected to the inside of the deodorizing chamber 1 near the air inlet pipe 11. The cross-section of one end of the guide plate 7 near the air inlet pipe 11 is triangular, and the upper and lower surfaces of the other end of the guide plate 7 are both arc-shaped. When a large amount of odor enters the inside of the deodorizing chamber 1, the high-efficiency purification mode is activated. The guide plate 7 is fixed between the two deodorizing channels to divert the flow. Its triangular cross-section design can quickly and evenly distribute the odor to the two deodorizing channels, avoiding congestion and uneven distribution of odor at the inlet, and ensuring that the two channels can work efficiently at the same time. The arc-shaped design of the other end of the guide plate 7 further optimizes the airflow path, reduces the resistance when the odor passes through, and allows the odor to enter the deodorizing channel more smoothly and fully contact the activated carbon plate 14, thereby improving the purification efficiency and effect of the entire device.

[0031] Multiple guide pipes 8 are fixed to both the upper and lower surfaces of the guide plate 7. One end of the guide pipe 8 near the air inlet pipe 11 is flared, and the other end of the guide pipe 8 is inclined. When a large amount of odorous gas is introduced into the deodorizing chamber 1, the multiple guide pipes 8 are fixed to the upper and lower surfaces of the guide plate 7 respectively. The flared design can further expand the entry area of ​​the odorous gas, so that the odorous gas can be more dispersed and evenly distributed before entering the deodorizing channel. The inclined setting of the other end of the guide pipe 8 plays the role of guiding the airflow, so that the odorous gas can smoothly enter the deodorizing channel along a specific direction, avoiding airflow turbulence and backflow. These design details of the guide pipes 8 together optimize the airflow distribution of odorous gas at the device inlet, ensuring that the odorous gas can enter the deodorizing channel in the best condition and make full contact with the activated carbon plate 14, thereby improving the purification efficiency and stability of the entire activated carbon deodorizing device, so that the device can better cope with the treatment needs of a large amount of odorous gas in the high-efficiency purification mode.

[0032] like Figures 1 to 4 As shown, an adsorption plate 9 is fixedly attached to the arc-shaped inclined surface of the guide plate 3; multiple activated carbon fiber felts 91 are fixedly attached to the adsorption plate 9; when a large amount of odorous gas passes through the guide plate 3, the adsorption plate 9, together with the multiple activated carbon fiber felts 91 on its surface, can further adsorb and capture the tiny particles and harmful substances in the odorous gas. The activated carbon fiber felts 91 have a rich microporous structure and a large specific surface area, which enables them to quickly and effectively adsorb impurities in the odorous gas, enhancing the purification effect of the odorous gas. At the same time, the combination of the adsorption plate 9 and the arc-shaped inclined surface of the guide plate 3 performs secondary purification while guiding the odorous gas, further improving the purity of the odorous gas when it passes through the working deodorization channel, reducing the residue of harmful substances in the odorous gas, making the gas treated by this activated carbon deodorization device cleaner and more environmentally friendly, meeting higher emission standards, and providing a more reliable guarantee for odor treatment in the sewage treatment process.

[0033] The diameter of the air inlet near the air inlet pipe 11 on the deodorizing chamber 1 is smaller than the diameter of the air inlet near the air outlet pipe 12; the activated carbon plate 14 is made of high-quality coal-based honeycomb activated carbon. When a large amount of odorous gas is introduced into the deodorizing chamber 1 for purification, the gradually expanding and contracting channel design allows the odorous gas to gradually accelerate when entering the device, forming a stable airflow, and gradually decelerate when exiting. This facilitates efficient purification of the odorous gas by the activated carbon plate 14, improving purification efficiency. Furthermore, the activated carbon plate 14 is made of high-quality coal-based honeycomb activated carbon, which has a well-developed pore structure and a large specific surface area, enabling efficient adsorption of harmful substances in the odorous gas. It also possesses high mechanical strength, wear resistance, and corrosion resistance, allowing it to work stably for extended periods in harsh wastewater treatment environments. This ensures the reliability and durability of the deodorizing device, enabling the entire activated carbon deodorizing device to maintain efficient and stable operation when processing large amounts of odorous gas.

[0034] Working Process: During wastewater treatment, especially in the pretreatment and sludge treatment stages, malodorous gases containing hydrogen sulfide, ammonia, and other components are generated. When using high-efficiency activated carbon to purify and deodorize these large amounts of odorous gases, the deodorization unit 1 serves as the main purification component. The inlet pipe 11 is connected to the odor delivery pipe, and the outlet pipe 12 is used to discharge the purified gas. The activated carbon plates 14 are made of high-efficiency activated carbon. First, open the two assembly plates 13 and insert the two activated carbon plates 14 into the center of the two deodorization channels respectively. This activated carbon deodorization device... There are two purification modes: alternating purification mode and high-efficiency purification mode. In alternating purification mode, a large amount of odorous gas is introduced into the deodorizing chamber 1 through the air inlet pipe 11. At this time, an electric slider drives the partition plate 16 to slide on the guide rail 15. The partition plate 16 blocks the center of one deodorizing channel, while the other deodorizing channel is open. After the odorous gas enters the deodorizing chamber 1, it passes through the open deodorizing channel and is purified at the activated carbon plate 14. The purified gas is discharged from the air outlet pipe 12, while the blocked deodorizing channel is in a resting state. The two deodorizing channels are switched so that the activated carbon plates 14 inside can regain their adsorption capacity. When the activated carbon plates 14 in the working deodorizing channel are saturated, the electric slider drives the partition plate 16 to slide, exchanging the working state of the two deodorizing channels to achieve alternating purification and ensure the continuous and efficient operation of the deodorizing device. At the same time, in the alternating purification mode, when the activated carbon plates 14 in the deodorizing channel are saturated and need to be replaced, the deodorizing channel with saturated activated carbon plates 14 is closed, and the assembly plate 13 is removed and the activated carbon plates 14 are replaced directly, which can achieve efficient and continuous processing without stopping the machine. In the high-efficiency purification mode, the two electric sliders drive the corresponding partition plates 16 to slide at the same time, so that both deodorizing channels are in the open state. At this time, a large amount of odorous gas enters the deodorizing machine box 1 from the air inlet pipe 11 and passes through the two deodorizing channels at the same time. After the odorous gas reaches the two activated carbon plates 14, it is purified at the same time. The purified gas is discharged from the air outlet pipe 12 together. This mode can efficiently purify a large amount of odorous gas in a short time, meet the deodorization needs of emergency and high load, efficiently process a large amount of odorous gas, and improve the purification efficiency.When assembling the two activated carbon plates 14, the two fixing brackets 2 are fixed relative to each other at the center of the two deodorization channels inside the deodorizing casing 1. After opening the two assembly plates 13, the activated carbon plates 14 are first fixed onto the sliding bracket 22. Then, the round holes on the sliding bracket 22 are aligned with the two guide rods 21, and the sliding bracket 22 is inserted into the guide rods 21. Finally, one end of the sliding bracket 22 is fixed onto the fixing bracket 2 using screws. At this point, the activated carbon plates 14 are securely installed at the center of the deodorization channel. This installation method is not only structurally stable but also facilitates subsequent installations. The disassembly and replacement of the activated carbon plate 14 is simple. When the activated carbon plate 14 needs to be replaced, simply unscrew the screws and slide the sliding bracket 22 off the guide rod 21 to easily remove the old activated carbon plate 14. Then, install the new activated carbon plate 14 in the same way. The whole process does not require large-scale disassembly of the entire deodorization device, saving maintenance time and costs. At the same time, the cooperative design of the fixed bracket 2, guide rod 21, and sliding bracket 22 also ensures the precise positioning of the activated carbon plate 14 in the deodorization channel, so that the odor can pass through the activated carbon plate 14 evenly, improving the deodorization efficiency. When odorous gas enters the deodorizing chamber 1 for purification, one activated carbon plate 14 in the alternating purification mode of the two deodorizing channels is sufficient for efficient deodorization. As the electric slider moves the partition plate 16 to slide and block one deodorizing channel, the guide plate 3 on the partition plate 16 also slides accordingly. After the partition plate 16 blocks one deodorizing channel, the arc-shaped inclined surface of the guide plate 3 can guide the passing odorous gas to the activated carbon plate 14 of the other deodorizing channel, so that the odorous gas can pass through the working deodorizing channel more concentratedly and smoothly, avoiding the formation of eddies and stagnation of odorous gas at the blockage point, thereby improving the purification efficiency and effect of odorous gas. At the same time, the arc-shaped inclined surface design of the guide plate 3 also reduces the resistance when odorous gas passes through, making the entire activated carbon deodorizing device more efficient during operation. When replacing the saturated activated carbon plate 14, the electric slider drives the partition plate 16 to slide, and the guide plate 3 simultaneously approaches the transmission component and pushes it. The pushed transmission component simultaneously drives the rotating rod 41 on the fixed rod 4 to rotate, causing the barrier plate 42 to rotate and fit against the mating plate 43. The barrier plate 42, together with the mating plate 43 and the partition plate 16, seals the saturated activated carbon plate 14. At this time, the operator can open the assembly plate 13, remove the saturated activated carbon plate 14 from the sliding frame 22, and replace it with a new activated carbon plate 14. After replacing the new activated carbon plate 14, the electric slider drives the partition plate 16 to slide back to its original position. The guide plate 3 moves away from the transmission component, and the transmission component is no longer squeezed and resets itself. The barrier plate 42 leaves the mating plate 4. 3. Restoring the initial state allows the deodorization channel to reopen, and the entire replacement process does not require stopping the flow of odorous gases. This achieves continuous activated carbon replacement without shutting down the system, improving the efficiency and continuity of the deodorization device, reducing the interruption time of odor treatment caused by downtime for activated carbon replacement, and ensuring the stability and reliability of odor treatment during wastewater treatment. When the electric slider drives the partition plate 16 and guide plate 3 to slide, the guide plate 3 can squeeze and push the toothed plate 5 to slide. The elastic element 51 is squeezed and contracted under force. During the sliding process of the toothed plate 5, its toothed structure meshes with the toothed structure of the toothed ring 52, causing the toothed ring 52 to rotate. Since the toothed ring 52 is fixed to the rotating rod 41, the rotation of the toothed ring 52 will synchronously drive the rotating rod 41 to rotate, thereby reducing the resistance. The partition plate 42 rotates accordingly. When the partition plate 42 rotates to fit with the mating plate 43, the sealing action at the saturated activated carbon plate 14 is completed. At this time, the staff can open the assembly plate 13 according to the established procedure to safely and efficiently replace the saturated activated carbon plate 14. After the new activated carbon plate 14 is installed, the electric slider drives the partition plate 16 to slide and reset. The guide plate 3 moves away from the toothed plate 5. After the elastic element 51 loses the squeezing force, it returns to its original state. The toothed plate 5 resets under the action of the elastic element 51. The partition plate 42 leaves the mating plate 43, and the deodorization channel is restored to a smooth state. The entire device continues to operate stably. The design of this transmission component ensures the smooth operation of replacing activated carbon without stopping the machine, which greatly improves the working efficiency and continuity of the deodorization device. When odorous gas is introduced into the deodorizing chamber 1, the exhaust fan 6, fixed inside the air inlet pipe 11, rotates to extract the odorous gas. The concentrating ring plate 61, fixed at one end of the deodorizing chamber 1, guides the odorous gas. With the combined action of the exhaust fan 6 and the concentrating ring plate 61, the odorous gas can enter the deodorizing chamber 1 at a stable and uniform flow rate. This avoids problems such as excessive local purification pressure and insufficient purification caused by uneven odor gas flow, providing a good airflow foundation for subsequent efficient deodorization. Simultaneously, the stable operation of the exhaust fan 6 ensures the continuous operation of the entire activated carbon deodorizing device. The stable intake process reduces potential device malfunctions and decreased purification efficiency caused by intake fluctuations, further enhancing the device's reliability and stability. Furthermore, the guiding design of the air-gathering ring plate 61 allows odorous gas to enter the deodorization channel more precisely, ensuring full contact with the activated carbon plate 14 and improving odor purification efficiency. When a large amount of odorous gas enters the deodorization chamber 1, the high-efficiency purification mode is activated. The guide plate 7, fixed between the two deodorization channels, diverts the gas. Its triangular cross-section design quickly and evenly distributes the odorous gas into the two channels, preventing odor from escaping. To address congestion and uneven distribution at the entrance, and ensure efficient operation of both channels simultaneously, the curved design of the other end of the baffle 7 further optimizes the airflow path, reducing resistance to odor passage and allowing the odor to enter the deodorization channel more smoothly and make full contact with the activated carbon plate 14, thereby improving the purification efficiency and effect of the entire device. When a large amount of odor enters the deodorization chamber 1, multiple guide pipes 8 are fixed to the upper and lower surfaces of the baffle 7, respectively. Their funnel-shaped design further expands the odor entry area, ensuring that the odor enters the deodorization channel more effectively. The airflow can be more dispersed and evenly distributed in front of the channel, while the inclined setting at the other end of the guide pipe 8 plays the role of guiding the airflow, so that the odor can smoothly enter the deodorization channel along a specific direction, avoiding airflow turbulence and backflow. These design details of the guide pipe 8 together optimize the airflow distribution of odor at the device inlet, ensuring that the odor can enter the deodorization channel in the best state and make full contact with the activated carbon plate 14, thereby improving the purification efficiency and stability of the entire activated carbon deodorization device, so that the device can better cope with the treatment needs of a large amount of odor in the high-efficiency purification mode. When a large amount of odorous gas passes through the guide plate 3, the adsorption plate 9, together with the multiple activated carbon fiber felts 91 on its surface, can further adsorb and capture the tiny particles and harmful substances in the odorous gas. The activated carbon fiber felts 91 have a rich microporous structure and a large specific surface area, which enables them to quickly and effectively adsorb impurities in the odorous gas, enhancing the purification effect of the odorous gas. At the same time, the combination of the adsorption plate 9 and the arc-shaped inclined surface of the guide plate 3 performs secondary purification while guiding the odorous gas, further improving the purity of the odorous gas when it passes through the working deodorization channel, reducing the residue of harmful substances in the odorous gas, and making the gas treated by this activated carbon deodorization device cleaner and more environmentally friendly, meeting higher emission standards and providing a more reliable guarantee for odor treatment in the sewage treatment process. When a large amount of odorous gas is introduced into the deodorizing chamber 1 for purification, the diameter of the air inlet near the inlet pipe 11 on the deodorizing chamber 1 is smaller than the diameter of the air inlet near the outlet pipe 12. This gradually expanding and contracting channel design allows the odorous gas to gradually accelerate when entering the device, forming a stable airflow, and gradually decelerate when exiting. This facilitates the efficient purification of the odorous gas by the activated carbon plate 14, improving the purification efficiency. At the same time, the activated carbon plate 14 is made of high-quality coal-based honeycomb activated carbon material. This material has a well-developed pore structure and a huge specific surface area, which can efficiently adsorb harmful substances in the odorous gas. In addition, it has high mechanical strength, wear resistance, and corrosion resistance, and can work stably for a long time in harsh sewage treatment environments, ensuring the reliability and durability of the deodorizing device. This allows the entire activated carbon deodorizing device to maintain a highly efficient and stable operating state when treating a large amount of odorous gas.
