Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas purification technology, specifically an activated carbon gas purification device. Background Technology
[0002] Gas purification refers to the process of removing pollutants from gases using physical, chemical, or biological methods to meet emission standards or specific usage requirements. Activated carbon gas purification equipment efficiently removes organic matter, odors, and some inorganic pollutants from waste gases through physical and chemical adsorption.
[0003] The activated carbon gas purification equipment consists of a housing, an adsorption unit, and inlet and outlet air ducts. During operation, the gas containing pollutants enters the housing through the inlet air duct. The gas flows through the adsorption unit composed of porous activated carbon inside the housing for purification. The purified gas is then discharged through the outlet air duct.
[0004] After a period of use, existing activated carbon purification devices are prone to dust accumulation in components such as filter bags, leading to airflow blockage, increased equipment operating resistance, reduced processing capacity, and shortened component lifespan, requiring frequent replacement and cleaning. This not only increases operating costs but also reduces purification efficiency, making it difficult to achieve the expected purification effect. Therefore, an activated carbon gas purification device is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and address the problems mentioned in the background art, such as dust accumulation on filter bags and other components of existing activated carbon purification devices after a period of use, leading to airflow blockage, increased equipment operating resistance, reduced processing capacity, and shortened component lifespan requiring frequent replacement and cleaning, which not only increases operating costs but also reduces purification efficiency and makes it difficult to achieve the expected purification effect, this utility model proposes an activated carbon gas purification device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An activated carbon gas purification device of this utility model includes a purification box. A fixing plate is fixedly installed inside the upper end of the purification box. A through hole is opened in the center of the fixing plate, and a fan is fixedly installed in the through hole. Three rectangular mounting slots are arrayed on the upper end of opposite sides of the purification box. An activated carbon plate, a catalytic purification plate, and a molecular sieve plate are sequentially arranged from top to bottom below the fixing plate and slidably installed in the rectangular mounting slots. A partition is fixedly installed inside the purification box below the molecular sieve plate. A rotating shaft is rotatably installed in the center of the partition. Multiple air holes are arrayed at the bottom of the partition. An mounting plate is fixedly installed inside the purification box below the partition. A roller brush is fixedly installed through the mounting plate at the lower end of the rotating shaft. The roller brush is surrounded by multiple bag supports arranged in an array. The upper end of each bag support is rotatably mounted inside a mounting plate, and a rotating gear is fixedly mounted through the mounting plate. A drive gear is fixedly mounted at the same height as the upper end of the bag support on the upper end of the rotating shaft. The drive gear meshes with multiple rotating gears simultaneously. A dust collector bag is fitted onto the lower end of each bag support, and the upper end of the dust collector bag is fixedly mounted on the bag support. By setting up activated carbon plates, catalytic purification plates, and molecular sieve plates, multi-level and efficient purification of the gas is achieved, which can effectively remove various pollutants from the gas. At the same time, the drive gear on the rotating shaft meshes with the rotating gear on the bag support, driving the bag support and dust collector bag to rotate. This, in conjunction with the roller brush, cleans the surface of the dust collector bag, realizing the automatic cleaning function of the dust collector bag.
[0007] Preferably, an exhaust port is provided on one side of the top of the purification box, and a sealing plate is rotatably installed inside the exhaust port. Fixed shafts are fixedly installed on both sides of the inside of the top of the purification box, and electric telescopic rods are rotatably installed on each fixed shaft. The other end of the electric telescopic rods is rotatably installed on both sides of the sealing plate. By setting the cooperation structure between the electric telescopic rods and the sealing plate, the opening and closing angle of the sealing plate can be precisely controlled by the extension and retraction of the electric telescopic rods, thereby flexibly adjusting the exhaust volume of the exhaust port to meet the gas emission requirements under different working conditions, and improving the flexibility and controllability of the equipment.
[0008] Preferably, a motor is fixedly mounted on the upper part of the partition plate on one side of the top of the rotating shaft. Both the rotating shaft and the top of the rotating shaft are fixedly mounted with bevel gears. The bevel gears are perpendicular to each other and mesh with each other. By setting up a transmission structure between the motor and the bevel gears, vertical transmission between the rotating shafts of the motor is realized, which can effectively transmit the power of the motor to the rotating shaft, drive the roller brush and the bag support to rotate, and ensure the cleaning effect on the dust collector bag.
[0009] Preferably, an air inlet is provided on one side of the lower end of the purification chamber, and a filter screen is installed inside the air inlet. The filter screen has mounting holes at all four corners, and the filter screen is fixedly installed inside the air inlet by fixing bolts. By setting up the filter screen, the gas entering the purification chamber can be initially filtered, intercepting larger particulate impurities and preventing them from entering the purification chamber and damaging components such as activated carbon plates, catalytic purification plates, molecular sieve plates, and dust collection bags. This extends the service life of the purification components and ensures the normal operation of the purification equipment.
[0010] Preferably, guide plates are fixedly installed at an angle on both sides of the lower end of the purification box. The guide plates are symmetrically arranged. A sliding groove is opened on one side of the lower end of the purification box. A dust collection box is slidably installed in the sliding groove at the bottom of the lower end of the guide plate. By setting the guide plate and the dust collection box, the guide plate can guide the dust and other impurities swept down by the roller brush into the dust collection box, which is convenient for centralized collection and treatment of dust.
[0011] Preferably, the fan, electric telescopic pole, and motor are all linearly connected to the PLC controller via power lines, and the PLC controller is used to control their start and stop. By controlling the start and stop of the fan, electric telescopic pole, and motor through the PLC controller, the automated control of the equipment is realized. Operators can conveniently control the operating status of the equipment through the PLC controller, which improves the ease of operation and intelligence level of the equipment.
[0012] The advantages of this utility model are:
[0013] 1. In the gas treatment process of this utility model, the fan is started to create negative pressure in the purification chamber. Gas enters through the inlet, passes through the filter screen to intercept larger particles of impurities, and then passes through the dust collector bag for secondary filtration. The motor is started, and the motor shaft drives the bevel gear to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft drives the roller brush to rotate, cleaning the surface of the dust collector bag. At the same time, through the meshing transmission of the drive gear and the rotating gear, the bag support and the dust collector bag rotate, so that the roller brush can thoroughly clean the surface of the bag. The dust swept off slides down the guide plate into the dust collection box under the action of gravity. Then, the gas that has undergone secondary filtration passes through the partition. The bottom pores pass sequentially through the activated carbon plate, catalytic purification plate, and molecular sieve plate for multi-level purification, removing organic pollutants and harmful gases. The purified gas is then discharged into the external environment through the through holes in the fixed plate and the exhaust port. This solves the problem that existing activated carbon purification devices tend to accumulate dust on components such as filter bags after a period of use, leading to airflow blockage, increased equipment operating resistance, reduced processing capacity, and shortened component lifespan, requiring frequent replacement and cleaning. This not only increases operating costs but also reduces purification efficiency, making it difficult to achieve the expected purification effect. This device improves gas purification efficiency.

[0022] Please see Figure 1-5As shown, an activated carbon gas purification device includes a purification chamber 1. A fixing plate 5 is fixedly installed inside the upper part of the purification chamber 1. A through hole is opened in the center of the fixing plate 5, and a fan 6 is fixedly installed in the through hole. Three rectangular mounting slots are arrayed on the upper part of opposite sides of the purification chamber 1. Activated carbon plate 7, catalytic purification plate 8, and molecular sieve plate 9 are arranged sequentially from top to bottom below the fixing plate 5 and slidably installed in the rectangular mounting slots. A partition plate 10 is arranged below the molecular sieve plate 9 and fixedly installed inside the purification chamber 1. A rotating shaft 14 is rotatably installed in the center of the partition plate 10. Multiple... The partition 10 has an air vent. A mounting plate 13 is fixedly installed below the partition 10 inside the purification chamber 1. A rotating shaft 14 passes through the mounting plate 13 and is fixedly mounted with a roller brush 16. Multiple bag supports 17 are arranged in an array around the roller brush 16. The upper end of each bag support 17 is rotatably mounted inside the mounting plate 13 and a rotating gear 18 is fixedly installed through the mounting plate 13. A drive gear 15 is fixedly installed at the same height as the upper end of the rotating shaft 14 and the upper end of the bag support 17. The drive gear 15 meshes with multiple rotating gears 18 simultaneously. A dust collector bag 19 is fitted onto the lower end of each bag support 17. The upper end of the filter bag 19 is fixedly installed on the bag support 17. During operation, in the gas treatment process, the fan 6 is started to create a negative pressure in the purification chamber 1. The gas enters from the air inlet, passes through the filter screen 20 to intercept larger particles of impurities, and then passes through the dust collector bag 19 for secondary filtration. The motor 11 is started, and the rotating shaft of the motor 11 drives the bevel gear 12 to rotate, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the roller brush 16 to rotate, cleaning the surface of the dust collector bag 19. At the same time, through the meshing transmission of the drive gear 15 and the rotating gear 18, the bag support 17 and the dust collector bag 19 are driven to rotate, so that the roller brush 16 can clean the entire surface. The dust swept from the surface of the cloth bag slides down the guide plate 22 into the dust collection box 23 under the action of gravity. Then, the gas filtered for the second time passes through the air holes at the bottom of the partition plate 10 and passes through the activated carbon plate 7, the catalytic purification plate 8 and the molecular sieve plate 9 in sequence for multi-level purification treatment to remove organic pollutants, harmful gases and the like. After purification, the gas passes through the through holes of the fixed plate 5 and the exhaust port to be discharged to the outside environment. At the same time, the electric telescopic rod 4 is activated to extend and retract, driving the sealing plate 2 to rotate and adjust the opening angle of the sealing plate 2, thereby flexibly controlling the exhaust volume of the exhaust port to meet the gas emission requirements under different working conditions.
[0023] The purification chamber 1 has an exhaust port on one side of its top, and a sealing plate 2 is rotatably installed inside the exhaust port. Fixed shafts 3 are fixedly installed on both sides of the top of the purification chamber 1, and electric telescopic rods 4 are rotatably installed on each fixed shaft 3. The other end of the electric telescopic rods 4 is rotatably installed on both sides of the sealing plate 2. During operation, in the gas treatment process, the electric telescopic rods 4 are activated to extend and retract, driving the sealing plate 2 to rotate and adjust the opening angle of the sealing plate 2, thereby flexibly controlling the exhaust volume of the exhaust port to meet the gas emission requirements under different working conditions.
[0024] A motor 11 is fixedly mounted on the upper part of the partition plate 10 at one end of the rotating shaft 14. Both the rotating shaft of the motor 11 and the top end of the rotating shaft 14 are fixedly mounted with bevel gears 12. The bevel gears 12 are perpendicular to each other and mesh with each other. During operation, in the gas treatment process, the motor 11 is started, and its rotating shaft drives the bevel gears 12 to rotate, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the roller brush 16 to rotate. At the same time, the rotating shaft 14 drives the bag support 17 and the dust collector bag 19 to rotate through the drive gear 15 and the rotating gear 18. The roller brush 16 cleans the surface of the rotating dust collector bag 19. The bevel gears 12, drive gears 15 and rotating gears 18 are all treated with anti-corrosion.
[0025] An air inlet is provided on one side of the lower end of the purification chamber 1. A filter screen 20 is installed inside the air inlet. The filter screen 20 has mounting holes at all four corners and is fixedly installed inside the air inlet by fixing bolts 21. During operation, the fan 6 is started to create a negative pressure inside the purification chamber 1 during gas treatment. Gas is drawn in through the air inlet. When the gas passes through the filter screen 20, the filter screen 20 can effectively intercept larger particulate impurities in the gas entering the purification chamber 1, preventing these impurities from entering the purification chamber 1 and damaging components such as the activated carbon plate 7, catalytic purification plate 8, molecular sieve plate 9, and dust collection bag 19.
[0026] The purification chamber 1 has guide plates 22 fixedly installed on both sides of its lower interior at an incline. The guide plates 22 are symmetrically arranged. A sliding groove is opened on one side of the lower end of the purification chamber 1. A dust collection box 23 is slidably installed in the sliding groove at the bottom of the lower end of the guide plates 22. During operation, in the gas treatment process, the dust and other impurities swept down by the roller brush 16 slide down along the inclined guide plates 22 into the dust collection box 23 under the action of gravity, which facilitates the centralized collection and treatment of dust and avoids the accumulation of dust in the purification chamber 1, which affects the performance of the equipment. At the same time, the dust collection box 23 is slidably installed in the sliding groove, which is convenient for disassembly and cleaning.
[0027] The fan 6, electric telescopic rod 4, and motor 11 are all linearly connected to the PLC controller via power lines, and the PLC controller is used to control their start and stop. During operation, in the gas processing process, the operator can conveniently control the start and stop of the fan 6, electric telescopic rod 4, and motor 11 through the PLC controller to realize the automated control of the equipment and improve the ease of operation and intelligence level of the equipment.
[0028] Working principle: During gas treatment, the fan 6 is activated to create negative pressure inside the purification chamber 1. Gas enters through the inlet, passes through the filter screen 20 to intercept larger particles, and then passes through the dust collector bag 19 for secondary filtration. The motor 11 is activated, and the rotating shaft of the motor 11 drives the bevel gear 12 to rotate, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the roller brush 16 to rotate, cleaning the surface of the dust collector bag 19. At the same time, through the meshing transmission of the drive gear 15 and the rotating gear 18, the bag support 17 and the dust collector bag 19 rotate, allowing the roller brush 16 to thoroughly clean the surface of the bag. The swept-down dust slides down the guide plate 22 into the dust collection box 23 under the action of gravity. Then, the gas that has been filtered twice passes through the air holes at the bottom of the partition plate 10 and passes through the activated carbon plate 7, the catalytic purification plate 8 and the molecular sieve plate 9 in sequence for multi-level purification treatment to remove organic pollutants, harmful gases and the like. After purification, the gas passes through the through holes of the fixed plate 5 and the exhaust port to be discharged to the outside environment. At the same time, the electric telescopic rod 4 is activated to extend and retract, which drives the sealing plate 2 to rotate and adjust the opening angle of the sealing plate 2, thereby flexibly controlling the exhaust volume of the exhaust port to meet the gas emission requirements under different working conditions.
