Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas treatment equipment, and in particular relates to an activated carbon adsorption device. Background Technology

[0002] Activated carbon is widely used in waste gas treatment due to its excellent adsorption function, and activated carbon adsorption devices are commonly used waste gas treatment equipment.

[0003] In existing activated carbon adsorption devices, the activated carbon needs to be replaced regularly. The activated carbon is fixed to the support frame with bolts, which requires tools for disassembly and assembly, which is time-consuming, labor-intensive, and has low maintenance efficiency.

[0004] Existing patent document (publication number: CN221085135U) discloses "a waste gas adsorption device", which also has the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide an activated carbon adsorption device with a novel structure, simple assembly and disassembly of the activated carbon adsorption plate, and a fixing method that replaces bolt connection, making operation labor-saving and convenient.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An activated carbon adsorption device includes: a support frame and a housing, the housing being mounted on the support frame, with an air inlet at the bottom and an exhaust outlet at the top; characterized in that: activated carbon adsorption plates are longitudinally distributed inside the housing, and U-shaped brackets are provided on the inner wall of the housing, with the activated carbon adsorption plates inserted between two symmetrically distributed U-shaped brackets, and elastic pads provided on the inner wall of the U-shaped brackets, the elastic pads contacting the surface of the activated carbon adsorption plates; an operating port is opened on the side of the housing, and a door is rotatably connected to the housing, the door closing the operating port, and a locking element connecting the door and the housing. This adsorption device has a novel structure, and the activated carbon adsorption plates are easy to assemble and disassemble, replacing the bolt connection method, making operation labor-saving and convenient.

[0008] Furthermore, the chamber is equipped with a throttling orifice plate, located below the activated carbon adsorption plate. As the exhaust gas rises, it is obstructed by the throttling orifice plate, reducing its flow velocity and prolonging its residence time within the chamber. This increases the contact time between the exhaust gas and the activated carbon adsorption plate, thereby improving the adsorption effect.

[0009] Furthermore, the housing is equipped with a stepped section, and a pressure block is rotatably connected to the inner wall of the housing. The pressure block presses down against the orifice plate, limiting the orifice plate to the stepped section. During installation, the orifice plate is placed on the stepped section, and then the pressure block is rotated downwards so that its end presses against the upper surface of the orifice plate, preventing the orifice plate from moving upwards and being unaffected by the impact of exhaust gas flow, resulting in high installation stability. Rotating the pressure block upwards removes the orifice plate, allowing it to be removed for easy replacement and cleaning, making it highly practical.

[0010] Furthermore, the door is equipped with an ear block, which has a first vertical through hole corresponding to one end of the locking element. The body is equipped with an ear seat, which has a second vertical through hole corresponding to the other end of the locking element. By inserting one end of the locking element into the first vertical through hole and the other end into the second vertical through hole from top to bottom, the locking element connects both the ear block and the ear seat, thereby restricting the free rotation of the door. The locking element is easy to insert and remove, effortless, convenient, and easy to use.

[0011] Furthermore, the door has an inner protrusion, and a sealing ring is located on the outside of the operating opening. The sealing ring is adapted to fit the inner protrusion. When the door is closed, the inner protrusion is embedded in the sealing ring, making tight contact with very small gaps, resulting in good sealing performance and preventing air leakage.

[0012] Furthermore, the U-shaped bracket is equipped with a mounting block, which is fixed to the inner wall of the box by bolts. The mounting block is reliable, easy to install and remove, and can be used immediately, making it flexible and convenient.

[0013] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0014] 1. During the upward flow of exhaust gas, the flow rate is reduced due to the obstruction of the throttling orifice plate, which prolongs the residence time of the exhaust gas in the chamber and increases the contact time between the exhaust gas and the activated carbon adsorption plate, thereby improving the adsorption effect.

[0015] During installation, place the orifice plate on the stepped part, then rotate the pressure block downwards so that its end presses against the upper surface of the orifice plate, making close contact and creating high friction. The pressure block prevents the orifice plate from moving upwards, ensuring it is not affected by the exhaust gas flow and has high installation stability. Rotating the pressure block upwards removes the orifice plate, making it easy to replace and clean, and enhancing its practicality.

[0016] 2. During installation, insert the activated carbon adsorption plate horizontally into the groove of the U-shaped bracket. The elastic pad is in close contact with the surface of the activated carbon adsorption plate, resulting in high friction. The activated carbon adsorption plate is not easy to detach from the U-shaped bracket, ensuring stability and reliability. It is also easy to disassemble and replace, replacing the bolt connection method, making operation labor-saving and convenient. Attached Figure Description

Detailed Implementation

[0025] like Figures 1 to 6 As shown, this utility model discloses an activated carbon adsorption device, comprising: a support frame 1 and a housing 2. The housing 2 is mounted on the support frame 1. The bottom of the housing 2 is provided with an air inlet 3, and the top of the housing 2 is provided with an exhaust outlet 4. The housing 2 is provided with a throttling orifice plate 5 and an activated carbon adsorption plate 6. The throttling orifice plate 5 is located below the activated carbon adsorption plate 6. The activated carbon adsorption plate 6 is longitudinally distributed and includes a frame 7 and honeycomb activated carbon blocks 8. The honeycomb activated carbon blocks 8 are nested in the frame 7. The honeycomb activated carbon blocks 8 can adsorb volatile organic compounds, low-concentration pollutants, and remove malodorous gases in the waste gas.

[0026] As the exhaust gas rises, it is blocked by the throttling orifice plate 5, which reduces the flow rate and prolongs the residence time of the exhaust gas in the housing 2. This helps to increase the contact time between the exhaust gas and the activated carbon adsorption plate 6, thereby improving the adsorption effect.

[0027] The housing 2 has a stepped section 9 inside, and a pressure block 10 is rotatably connected to the inner wall of the housing 2. The pressure block 10 presses down against the throttling orifice plate 5, so that the throttling orifice plate 5 is limited on the stepped section 9.

[0028] During installation, place the orifice plate 5 on the step 9, and then rotate the pressure block 10 downwards so that its end presses against the upper surface of the orifice plate 5, making close contact and creating high friction. The pressure block 10 prevents the orifice plate 5 from moving upwards and is not affected by the impact of the exhaust gas flow, resulting in high installation stability. Rotate the pressure block 10 upwards so that it no longer presses against the orifice plate 5, and the orifice plate 5 can be removed for easy replacement and cleaning, making it highly practical.

[0029] The inner wall of the housing 2 is provided with a U-shaped card seat 11. The activated carbon adsorption plate 6 is inserted between two symmetrically distributed U-shaped card seats 11. The inner wall of the U-shaped card seat 11 is provided with an elastic pad 12. The material of the elastic pad 12 can be silicone rubber or silicone. The elastic pad 12 is in contact with the surface of the activated carbon adsorption plate 6.

[0030] During installation, the activated carbon adsorption plate 6 is inserted horizontally into the groove of the U-shaped bracket 11. The elastic pad 12 is in close contact with the surface of the activated carbon adsorption plate 6, resulting in high friction. The activated carbon adsorption plate 6 is not easy to detach from the U-shaped bracket 11, making it stable and reliable. It is also easy to disassemble and replace, replacing the bolt connection method, which is labor-saving and convenient.

[0031] The U-shaped bracket 11 has a mounting block 13 on one side. The mounting block 13 is fixed to the inner wall of the box 2 by bolts. It is reliable, easy to disassemble and assemble, and can be used as soon as it is installed. It is flexible and convenient.

[0032] An operating port 14 is provided on the side of the box body 2. A door 15 is rotatably connected to the box body 2. The door 15 closes the operating port 14. A locking element 16 is connected between the door 15 and the box body 2. The door 15 is provided with an ear block 17. The ear block 17 is provided with a first vertical through hole 21 corresponding to one end of the locking element 16. The box body 2 is provided with an ear seat 18. The ear seat 18 is provided with a second vertical through hole 22 corresponding to the other end of the locking element 16.

[0033] Insert one end of the locking member 16 into the first vertical through hole 21 and the other end into the second vertical through hole 22 from top to bottom, so that the locking member 16 connects the ear block 17 and the ear seat 18 at the same time, thereby restricting the free rotation of the box door 15. The locking member 16 is easy to insert and remove, labor-saving and convenient, and easy to use. Pulling the locking member 16 upwards can open the box door 15 and disassemble and assemble the activated carbon adsorption plate 6, which is simple and convenient.

[0034] The door 15 has an inner protrusion 19, and the outer side of the operating port 14 has a sealing ring 20, which is adapted to the inner protrusion 19. When the door 15 is closed, the inner protrusion 19 is embedded in the sealing ring 20, and the two are in close contact with very small gaps, resulting in good sealing performance and preventing air leakage.

[0035] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
