Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an adsorption tank for waste gas treatment. Background Technology

[0002] Waste gas refers to a mixture of gases containing harmful or unhelpful components that are generated and emitted into the atmosphere during human production, daily life, and other activities. Its sources are widespread and its composition complex. In the industrial sector, it refers to gases produced by factories, mines, power plants, etc., through the combustion of fuels (such as coal and oil), chemical reactions (such as chemical synthesis and metal smelting), or material processing (such as plastics processing and painting). Common components include sulfur dioxide, nitrogen oxides, volatile organic compounds, particulate matter, and carbon monoxide. In daily life, vehicle exhaust, gases produced by burning fossil fuels for residential heating, and flue gas released from waste incineration also fall under the category of waste gas. If most waste gases are emitted directly without treatment, they will not only damage the atmospheric environment and cause pollution problems such as smog and acid rain, but may also harm human health, including the respiratory and nervous systems, through inhalation or contact. Therefore, they must be treated to meet standards through technologies such as adsorption, combustion, and filtration before they can be discharged in compliance with regulations.

[0003] Existing equipment often uses a single filtration structure to intercept solid particles in exhaust gas. However, the filtration precision is poorly designed and lacks a real-time cleaning mechanism. When larger particles in the exhaust gas adhere to the surface of the filter components, they easily accumulate and form blockages, leading to a significant decrease in filtration efficiency. This not only affects the subsequent exhaust gas flow rate but also increases the equipment's operating resistance, sometimes requiring frequent shutdowns for disassembly and cleaning, severely reducing overall treatment efficiency. For impurities collected during the filtration process, existing equipment often requires disassembling the outer casing for cleaning, a complex and time-consuming procedure. Replacing saturated activated carbon is also inconvenient, either requiring complete disassembly of the adsorption module or lacking convenient inlet and outlet channels, resulting in long maintenance cycles, high labor costs, and prolonged equipment downtime during maintenance, affecting the continuity of exhaust gas treatment in continuous production processes. Furthermore, the support structure design of some equipment is unreasonable, leading to instability during long-term operation and increasing the risk of equipment failure. Therefore, we propose an adsorption tank for exhaust gas treatment. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention solves the problem that existing equipment often only has a single filtration structure to intercept solid particles in exhaust gas. However, the filtration precision lacks reasonable design and there is no real-time cleaning mechanism. When larger particles in the exhaust gas adhere to the surface of the filter components, they easily accumulate and form blockages, leading to a significant decrease in filtration efficiency. This not only affects the subsequent exhaust gas flow rate but also increases the equipment's operating resistance, sometimes requiring frequent shutdowns for disassembly and cleaning, severely reducing overall processing efficiency. For impurities collected during the filtration process, existing equipment often requires disassembling the outer casing for cleaning, which is a complex and time-consuming process. Furthermore, replacing saturated activated carbon is inconvenient, either requiring the complete disassembly of the adsorption module or lacking convenient inlet and outlet channels. This results in long maintenance cycles, high labor costs, and prolonged equipment downtime during maintenance, affecting the continuity of exhaust gas treatment in continuous production processes.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adsorption tank for treating waste gas includes:

[0009] The tank has an inlet pipe and an outlet pipe fixedly installed at both ends. An inlet and an outlet valve are provided on the outer wall of the tank. The tank is located between the inlet and the outlet valve. A filter plate is installed inside the tank. A block is provided on the side of the filter plate near the inlet pipe. Brushes are fixedly installed on the upper and lower sides of the block. Scrapers are provided on the front and rear sides of the block. Baffles are symmetrically arranged inside the tank between the inlet and the outlet valve. Activated carbon is placed inside the tank between the two baffles.

[0010] A limiting frame is fixedly installed on the outer wall of the tank. The limiting frame is located below the filter plate. A drawer is slidably installed inside the limiting frame. One end of the drawer passes through the limiting frame and extends to the outside.

[0011] A power unit, located inside the tank, is used to drive the rotation of two scrapers and two brushes.

[0012] Preferably, the power assembly includes a protective shell, which is disposed inside the tank and located on the side of the filter plate near the air outlet pipe. A servo motor is fixedly installed inside the protective shell, and the output shaft of the servo motor passes through the filter plate and is fixedly connected to the block. The protective shell is fixedly connected to the inner wall of the tank through two fixing columns.

[0013] Preferably, the output shaft of the servo motor is rotatably connected to the protective shell, the output shaft of the servo motor is rotatably connected to the filter plate, and the tank body is tightly welded to the fixed column and the protective shell.

[0014] Preferred options also include:

[0015] Two support plates are symmetrically fixedly installed on the outer wall of the tank, and the limiting frame and the discharge valve are located between the two support plates.

[0016] Preferably, the bristles of the brush are all pressed against the surface of the filter plate, and the scrapers of the scraper are all pressed against the surface of the filter plate.

[0017] Preferably, the filtration accuracy of the filter plate is 0.3-0.5μm, and the filtration accuracy of the partition is 0.3-0.5cm.

[0018] Preferably, the activated carbon is in granular form and can enter between the two partitions through the feed inlet, and the activated carbon can be discharged outside the whole device through the discharge valve.

[0019] Beneficial effects

[0020] 1. The waste gas to be treated enters the tank through the inlet pipe at one end of the tank. The first thing it comes into contact with is the filter plate inside the tank. The filter plate is set with a filtration accuracy of 0.3-0.5μm, which can accurately intercept larger solid particles in the waste gas and prevent these particles from entering the activated carbon adsorption area and causing blockage. This ensures the stable operation of the adsorption process. During the filtration process, in order to prevent particles from accumulating on the surface of the filter plate and affecting the filtration efficiency, the power unit will start synchronously. The servo motor in the protective shell drives the block to rotate through the output shaft. The brushes on the upper and lower sides of the block are always in contact with the surface of the filter plate. As the block rotates, it cleans the filter plate from all directions. At the same time, the scrapers on the front and rear sides also rotate in contact with the surface of the filter plate and scrape off the particles swept off by the brushes and some stubborn impurities. The scraped impurities will fall naturally into the drawer located below the filter plate, realizing the real-time cleaning of the filter plate and maintaining its continuous filtration capacity.

[0021] 2. The purified waste gas, after deep adsorption, will continue to flow to the other end of the tank and eventually be discharged outside the tank through the outlet pipe, achieving compliant emissions. During long-term operation, the equipment also requires regular maintenance. On the one hand, the drawer inside the limit frame can be pulled out to clean the collected impurities. After cleaning, the drawer can be pushed back into place for reuse. On the other hand, when the activated carbon adsorption capacity reaches saturation, new granular activated carbon can be added between the two baffles through the feed port on the outer wall of the tank. At the same time, the discharge valve can be opened to discharge the saturated old activated carbon outside the tank, completing the replacement of activated carbon and ensuring that the adsorption tank always maintains a high efficiency in waste gas treatment. In addition, the symmetrically installed support plates on the outside of the tank provide stable support for the entire equipment, ensuring the structural stability of the equipment during operation.

[0029] Example 1:

[0030] Please see Figure 1 - Figure 5 As shown in the figure, this embodiment provides an adsorption tank for waste gas treatment.

[0031] Tank 1 has an inlet pipe 2 and an outlet pipe 3 fixedly installed at both ends. An inlet 4 and an outlet valve 10 are located on the outer wall of tank 1, with tank 1 situated between the inlet 4 and the outlet valve 10. A filter plate 13 is installed inside tank 1. A block 14 is positioned on the side of filter plate 13 closest to the inlet pipe 2. Brushes 16 are fixedly installed on both the top and bottom sides of block 14, and scrapers 15 are installed on both the front and back sides of block 14. Partitions 11 are symmetrically arranged inside tank 1 between the inlet 4 and the outlet valve 10, and activated carbon 12 is placed inside tank 1 between the two partitions 11. A limiting frame 6 is fixedly installed on the outer wall of tank 1, positioned between the filter plate. Below 13, a drawer 7 is slidably installed within the limiting frame 6, with one end of the drawer 7 penetrating the limiting frame 6 and extending to the outside. A power assembly, located inside the tank 1, drives the rotation of two scrapers 15 and two brushes 16. The waste gas to be treated enters the tank through the inlet pipe 2 at one end of the tank 1, initially contacting the filter plate 13 inside the tank. This filter plate 13 has a filtration accuracy set at 0.3-0.5μm, accurately intercepting larger solid particles in the waste gas, preventing these particles from subsequently entering the adsorption area of ​​the activated carbon 12 and causing blockage, thus ensuring stable operation of the adsorption process. During filtration, to prevent particles from accumulating on the surface of the filter plate 13 and affecting filtration efficiency, the power assembly... Simultaneously, the servo motor 17 inside the protective shell 9 drives the block 14 to rotate via the output shaft. The brushes 16 on the upper and lower sides of the block 14, with their bristles always pressed against the surface of the filter plate 13, perform a comprehensive cleaning of the filter plate 13 as the block 14 rotates. At the same time, the scrapers 15 on the front and rear sides also rotate against the surface of the filter plate 13, scraping off the particles and some stubborn impurities swept away by the brushes 16. The scraped impurities will fall naturally into the drawer 7 located below the filter plate 13, achieving real-time cleaning of the filter plate 13 and maintaining its continuous filtration capacity. The purified exhaust gas, after deep adsorption, will continue to flow to the other end of the tank 1 and finally be discharged outside the tank through the exhaust pipe 3, achieving compliant emissions. During long-term operation, the equipment also requires regular maintenance. On the one hand, the drawer 7 inside the limit frame 6 can be pulled out to clean the collected impurities. After cleaning, the drawer 7 can be pushed back into place for reuse. On the other hand, when the adsorption capacity of the activated carbon 12 reaches saturation, new granular activated carbon 12 can be added between the two partitions 11 through the feed port 4 on the outer wall of the tank 1. At the same time, the discharge valve 10 is opened to discharge the saturated old activated carbon 12 out of the tank, thus completing the replacement of the activated carbon 12 and ensuring that the adsorption tank always maintains a high efficiency in waste gas treatment. In addition, the support plates 5 symmetrically installed on the outer side of the tank 1 provide stable support for the entire equipment, ensuring the structural stability of the equipment during operation.

[0032] Example 2:

[0034] The power assembly includes a protective shell 9, which is located inside the tank 1 and on the side of the filter plate 13 near the air outlet pipe 3. A servo motor 17 is fixedly installed inside the protective shell 9. The output shaft of the servo motor 17 passes through the filter plate 13 and is fixedly connected to the block 14. The protective shell 9 is fixedly connected to the inner wall of the tank 1 through two fixed posts 8. The servo motor 17 inside the protective shell 9 drives the block 14 to rotate through the output shaft. The brushes 16 on the upper and lower sides of the block 14 are always in contact with the surface of the filter plate 13. As the block 14 rotates, it cleans the filter plate 13 in all directions. At the same time, the scrapers 15 on the front and rear sides also rotate in contact with the surface of the filter plate 13, scraping off the particles and some stubborn impurities swept off by the brushes 16. The scraped impurities will fall naturally into the drawer 7 located below the filter plate 13, realizing the real-time cleaning of the filter plate 13 and maintaining its continuous filtration capacity.

[0037] The output shaft of the servo motor 17 is rotatably connected to the protective shell 9, and the output shaft of the servo motor 17 is rotatably connected to the filter plate 13. The tank body 1 is tightly welded to the fixed column 8 and the protective shell 9 to ensure that the output shaft of the servo motor 17 can rotate normally on the protective shell 9, and to ensure that the output shaft of the servo motor 17 can rotate normally on the filter plate 13, and to ensure the structural stability of the tank body 1, the fixed column 8 and the protective shell 9.

[0038] Example 4:

[0039] This embodiment provides an adsorption tank for waste gas treatment, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] This also includes:

[0041] Two support plates 5 are symmetrically fixed on the outer side wall of the tank body 1, and the limiting frame 6 and the discharge valve 10 are located between the two support plates 5.

[0042] The two support plates 5 provide a stable support structure for the tank body 1, which enables the discharge valve 10 to remain stable when opening or closing, ensuring the accuracy and reliability of its operation.

[0043] Example 5:

[0044] This embodiment provides an adsorption tank for waste gas treatment, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] The bristles of the brush 16 are all pressed against the surface of the filter plate 13, and the blades of the scraper 15 are all attached to the surface of the filter plate 13. The bristles of the brush 16 are closely attached to the surface of the filter plate 13, which can effectively remove impurities and particles attached to the filter plate 13, ensuring the filtration effect of the filter plate 13 and preventing the efficiency of waste gas treatment from being affected by the accumulation of impurities. The blades of the scraper 15 act evenly on the surface of the filter plate 13, which can further scrape off the dirt that is difficult to clean on the filter plate 13, ensuring that the filter plate 13 is always kept clean, extending the service life of the filter plate 13, thereby ensuring the stable operation of the adsorption tank for waste gas treatment and good waste gas treatment effect.

[0046] Example 6:

[0047] This embodiment provides an adsorption tank for waste gas treatment, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] The filter plate 13 has a filtration accuracy of 0.3-0.5μm, and the filter screen of the partition 11 has a filtration accuracy of 0.3-0.5cm. The filter plate 13 adopts this filtration accuracy, which can effectively intercept impurity particles with a particle size greater than 0.3-0.5μm in the exhaust gas, perform fine filtration of the exhaust gas, and ensure that the discharged gas meets environmental protection standards. The filter screen of the partition 11 has a filtration accuracy in the range of 0.3-0.5cm to prevent the internally filled activated carbon 12 from leaking outward.

[0049] Example 7:

[0050] This embodiment provides an adsorption tank for waste gas treatment, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] The activated carbon 12 is in granular form and can enter between the two baffles 11 through the feed inlet 4. The activated carbon 12 can be discharged from the entire device through the discharge valve 10. When the activated carbon 12 is saturated or needs to be replaced, simply open the discharge valve 10 to discharge the waste activated carbon 12, and then refill the new granular activated carbon 12 through the feed inlet 4. There is no need to disassemble the entire adsorption tank in a complicated way, which greatly improves maintenance efficiency, reduces maintenance costs, and ensures that the adsorption tank for waste gas treatment can operate continuously and efficiently.

[0052] Working principle: The waste gas to be treated enters the tank through the inlet pipe 2 at one end of the tank body 1. The first contact is with the filter plate 13 inside the tank. The filtration accuracy of the filter plate 13 is set to 0.3-0.5μm, which can accurately intercept larger solid particles in the waste gas, preventing these particles from entering the adsorption area of ​​the activated carbon 12 and causing blockage, thus ensuring the stable operation of the adsorption process. During the filtration process, in order to prevent particles from accumulating on the surface of the filter plate 13 and affecting the filtration efficiency, the power component will start synchronously. The servo motor 17 in the protective shell 9 drives the block 14 to rotate through the output shaft. The brushes 16 on the upper and lower sides of the block 14 are always in contact with the surface of the filter plate 13. As the block 14 rotates, it cleans the filter plate 13 in all directions. At the same time, the scrapers 15 on the front and rear sides also rotate in contact with the surface of the filter plate 13, scraping off the particles and some stubborn impurities cleaned by the brushes 16. The scraped impurities will fall naturally into the drawer 7 located below the filter plate 13, achieving real-time cleaning of the filter plate 13 and maintaining its continuous filtration capacity. Then, it enters the deep adsorption purification stage. The waste gas that has passed the initial filtration will continue to flow into the activated carbon 12 adsorption area in the middle of the tank 1. This area is defined by two symmetrically arranged partitions 11. The filter screen of the partitions 11 has a precision of 0.3-0.5cm, which can not only allow the waste gas that has passed the initial filtration to enter smoothly, but also prevent the granular activated carbon 12 filled inside from leaking out. When the waste gas passes through the partitions 11 and enters the space between the two partitions 11, it will come into full contact with the granular activated carbon 12 filled therein. The activated carbon 12, with its rich pore structure and strong adsorption capacity, will efficiently adsorb the harmful gas components in the waste gas, trapping the harmful components in the pores of the activated carbon 12, thus purifying the waste gas.

[0053] The purified exhaust gas, after deep adsorption, will continue to flow to the other end of the tank 1 and eventually be discharged outside the tank through the exhaust pipe 3, achieving compliant emissions. During long-term operation of the equipment, regular maintenance is also required. On the one hand, the drawer 7 in the limit frame 6 can be pulled out to clean the collected impurities. After cleaning, the drawer 7 can be pushed back into place for reuse. On the other hand, when the adsorption capacity of the activated carbon 12 reaches saturation, new granular activated carbon 12 can be added between the two partitions 11 through the feed port 4 on the outer wall of the tank 1. At the same time, the discharge valve 10 is opened to discharge the saturated old activated carbon 12 outside the tank, completing the replacement of the activated carbon 12 and ensuring that the adsorption tank always maintains a high efficiency in exhaust gas treatment. In addition, the support plates 5 symmetrically installed on the outer side of the tank 1 provide stable support for the entire equipment, ensuring the structural stability of the equipment during operation.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
