Description

Technical Field

[0001] This invention relates to the field of waste gas purification technology, and in particular to a high-efficiency secondary activated carbon adsorption box. Background Technology

[0002] In the field of environmental protection and air pollution control, activated carbon, with its rich pore structure and excellent adsorption performance, has become a core material for treating volatile organic compounds, odorous gases and some harmful pollutants. Adsorption equipment based on activated carbon is widely used in industries such as chemical, coating, printing and furniture manufacturing.

[0003] Currently, mainstream activated carbon adsorption equipment on the market suffers from the dual limitations of single-stage and traditional two-stage structures. Specifically, the single-stage activated carbon chamber, due to its single-chamber adsorption, suffers from rapid adsorption saturation and limited purification efficiency, especially for waste gases containing complex components such as VOCs. S Odor molecules and other pollutants make it difficult to meet emission standards. While traditional two-stage activated carbon adsorption boxes employ a two-stage series design, they are mostly fixed structures with several technical shortcomings: the primary adsorption unit is prone to blockage due to the accumulation of particulate matter such as dust and paint mist in the exhaust gas, affecting continuous operation; unstable humidity during the secondary adsorption process leads to fluctuations in the adsorption performance of the modified activated carbon, failing to meet increasingly stringent environmental emission requirements and the actual needs of enterprises for cost reduction and efficiency improvement. Therefore, this application proposes a high-efficiency purification two-stage activated carbon adsorption box. Summary of the Invention

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1:

[0039] A high-efficiency purification secondary activated carbon adsorption box includes a filtration and humidification component, a dust removal component, a dehumidification component, a first purification chamber 3, and a second purification chamber 4. The filtration and humidification component includes an inlet filter 11, an inlet shell 12, a connecting plate 13, a frame 19, a barrier plate 18, a toner box 20, a first motor 21, an eccentric wheel 22, a top rod 23, a steel ball 27, a channel plate 34, and a component box 25.

[0040] The inlet filter 11 is connected to the inlet housing 12. The connecting plate 13 slides on both the inlet housing 12 and the frame 19. The connecting plate 13 fixes multiple toner cartridges 20 together. The frame 19 is fixedly connected to the inlet housing 12. The barrier plate 18 is fixedly connected between the frames 19.

[0041] The toner box 20 is disposed between the channel plates 34. The first motor 21 is fixedly connected to the component box 25. The eccentric wheel 22 is eccentrically fixedly connected to the output shaft of the first motor 21. The lower end of the push rod 23 abuts against the outer contour of the eccentric wheel 22. The push rod 23 is slidably connected to the component box 25. The steel ball 27 is disposed in the component box 25. The channel plate 34 is fixedly connected to the inner wall of the inlet shell 12.

[0042] When the filtration assembly starts working, exhaust gas is first introduced into the device, covering the inlet filter 11 with the exhaust gas outlet. The inlet filter 11 will initially filter the particulate matter in the exhaust gas, thus removing the particulate matter. After flowing into the inlet housing 12 of the device, the exhaust gas comes into contact with the toner cartridges 20 because multiple channel plates 34 divide the inlet housing 12 and there are multiple toner cartridges 20 between them. The particulate matter and moisture in the toner cartridges 20 will be adsorbed by the activated carbon powder in the toner cartridges 20.

[0043] Because the activated carbon powder absorbs moisture, it becomes damp, which makes it more suitable for adhering to dust in the exhaust gas. When the toner box 20 is working, the first motor 21 will run, and its output shaft will rotate. Since the output shaft of the first motor 21 is fixedly connected to the eccentric wheel 22, and the eccentric wheel is eccentrically set, the push rod 23 is in contact with the eccentric wheel 22.

[0044] The other end is fixedly connected to the toner box 20, so the rotation of the eccentric wheel 22 will push the push rod 23 up and down, thereby causing the toner box 20 to move up and down. This causes the activated carbon powder to move up and down in the toner box 20, which in turn makes the activated carbon powder rise and further increases the contact with moisture and particulate matter. When it absorbs moisture, the activated carbon powder will more easily adhere to dust due to the moisture, thereby further improving the filtration of dust by this device.

[0045] Since the steel ball 27 is placed in the toner box 20, when the toner box 20 moves up and down, the steel ball 27 will collide with the activated carbon powder, thereby breaking up the clumps and avoiding the performance degradation caused by the clumping of activated carbon powder.

[0046] Example 2:

[0047] The dust removal assembly includes a slider 8, a housing 9, a grinding belt 10, transmission wheels 28, a gear set 29, a belt drive assembly 30, and a second motor 31. The slider 8 slides on the air inlet side of the passage between the first purification chamber 3 and the second purification chamber 4. The slider 8 is fixedly connected to the housing 9, and the housing 9 is rotatably connected to the gear set 29. The grinding belt 10 is mounted on two transmission wheels 28, and the gear set 29 consists of two meshing gears.

[0048] An air outlet casing 1 is fixedly connected to the front of the second purification chamber 4. An air outlet filter 2 is fixedly connected to the air outlet casing 1. A partition 5 is fixedly connected between the first purification chamber 3 and the second purification chamber 4. An air distribution plate 6 is fixedly connected to the air inlet of both the first purification chamber 3 and the second purification chamber 4. Activated carbon 7 is fixedly connected to both the first purification chamber 3 and the second purification chamber 4. The belt drive assembly 30 consists of a drive belt and a pair of pulleys. The other pulley is fixedly connected to the output shaft of the second motor 31. The second motor 31 is fixedly connected to the mechanism casing 9.

[0049] The inlet end of the solenoid valve 26 is connected to the side of the gas baffle 35 away from the air pump 24. The outlet end of the solenoid valve 26 is connected to the inlet end of the connecting pipe 15, and the outlet end of the connecting pipe 15 is connected to the interior of the dehumidification plate 32. The dehumidification plate 32 is fixedly connected to the dehumidification pipe 33.

[0050] The dust removal component is used selectively to remove a layer of dust from the surface of the activated carbon 7 that comes into contact with the exhaust gas. Since the humidification component cannot completely remove dust from the exhaust gas, some dust will come into contact with and adhere to the surface of the activated carbon 7, clogging its micropores. The dust removal component can be installed at this time. Slide grooves 14 are provided on the inlet housing 12 and the frame 19, and support feet 16 are fixedly connected to the lower surfaces of both the inlet housing 12 and the outlet housing 1.

[0051] When the dust removal assembly is in use, the grinding belt 10 contacts the exhaust gas inflow end of the activated carbon 7. Since the output shaft of the second motor 31 is fixedly connected to the pulley in the belt drive assembly 30, and the belt drive assembly 30 consists of a pair of pulleys and a drive belt mounted on the pulleys, when one pulley rotates, the other pulley will also be powered and rotated by the drive belt. The other pulley is fixedly connected to a gear in the gear set 29, and the shaft connecting them is rotatably connected to the housing 9 of the mechanism. Therefore, when the belt drive assembly 30 rotates, the gear set 29 will also rotate, thereby driving the drive wheel 28 to rotate. There are two drive wheels 28, and they transmit power to each other through the grinding belt 10. The grinding belt 10 and the drive wheel 28 are assembled together, so the rotation of one drive wheel 28 will cause the grinding belt 10 to rotate as well, thereby partially removing carbon from the activated carbon 7, thus exposing the activated carbon 7 that is not blocked by dust.

[0052] Example 3:

[0053] The dehumidification assembly includes an air inlet 17, a connecting pipe 15, an air pump 24, a solenoid valve 26, a dehumidification plate 32, a dehumidification pipe 33, and a gas baffle 35.

[0054] The air inlet 17 is fixedly connected to the air inlet end of the air pump 24. The gas baffle 35 divides the interior of the component box 25 into two parts. The air inlet end of the air pump 24 is connected to the side of the gas baffle 35 away from the air pump 24. The solenoid valve 26 is fixedly installed on the inner wall of the component box 25. One gear is fixedly connected to a transmission wheel 28, and the other gear is fixedly connected to a pulley in the belt drive assembly 30.

[0055] When using the dehumidification unit, the solenoid valve 26 must first be opened, which will conduct the airflow. During normal operation, the air pump 24 draws air from the outside through the air inlet 17 and stores it in the component box 25 on the side away from the air pump 24. The gas partition 35 is used to divide the space in the component box 25 into two parts. The side away from the air pump 24 is used to store compressed air.

[0056] When solenoid valve 26 is opened, compressed air enters the connecting pipe 15 from the inlet of solenoid valve 26, and then enters the dehumidification plate 32. The dehumidification plate 32 is fixedly connected to multiple dehumidification pipes 33, and their internal spaces are interconnected, so compressed air is ejected from the air above the dehumidification pipes 33. Activated carbon 7 is installed on the dehumidification pipes 33. When the dehumidification component is working, compressed air is discharged from the micropores on the dehumidification pipes 33, thereby removing the internal moisture of the activated carbon 7 and preventing the performance of the activated carbon 7 from being degraded due to moisture.

[0057] It should be noted that there are multiple channel plates 34. There are gaps between the channel plates 34 to allow for ventilation. When exhaust gas enters one side of the toner cartridge 20, it passes through the gap between the first channel plate 34 and the inlet housing 12, then through the first set of toner cartridges 20, then through the gap between the second channel plate 34 and the inlet housing 12, and then through the third. The gaps are distributed as follows: top, bottom, top. The first gap is located at the top of the smallest channel plate 34, the second at the bottom of the second largest channel plate 34, and the third at the top of the largest channel plate 34. This connects the three sets of toner cartridges 20 together, forming an S-shaped channel.

[0058] Similarly, after the exhaust gas passes through the toner cartridge 20, it enters the activated carbon 7. The two purification chambers are connected by a partition 5, and the exhaust gas is actually transported by the activated carbon 7. Figure 6 The air flows into the air distribution plate 6 near the right side, then flows through each piece of activated carbon 7 in an S-shaped channel, and finally flows into the internal space through the notch on the return partition 5, and then flows to the air distribution plate 6 on the left side. Then, following the same principle as in the second purification chamber 4, it flows through six pieces of activated carbon and finally flows out of the device.

[0059] The air distribution plate 6 utilizes the principle of multi-hole throttling and resistance balance. After the airflow initially diffuses through the gradually expanding cavity, it is diverted and rectified through the evenly arranged circular holes on the plate surface. The stable pressure difference formed by the holes balances the wind pressure and flow velocity in the upper, lower, left, and right areas of the cavity, weakening the phenomena of deflection, direct rush and vortex, and transforming the turbulent air intake into a uniform and stable flow airflow across the entire cross section, thus achieving uniform air distribution throughout the entire area.

[0060] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
