Description

Technical Field

[0001] This invention relates to the field of organic waste gas treatment technology, and in particular to a highly efficient activated carbon adsorption structure for organic waste gas treatment. Background Technology

[0002] Organic waste gas pollutants are diverse in type and characteristics, thus requiring different treatment methods. Commonly used processes are mainly divided into two categories: recovery technology and destruction technology. Organic waste gas adsorption treatment can thoroughly purify waste gas, i.e., deep purification, especially for the purification of low-concentration waste gas, showing greater advantages than other methods. For example, Chinese patent CN118594193B discloses an organic waste gas separation and treatment device. Currently, in organic waste gas adsorption technology, the activated carbon component near the main inlet end usually has a larger processing capacity than the activated carbon component far from the main inlet end. For example, in an organic waste gas adsorption and filtration treatment system disclosed in Chinese patent CN119869151B, the activated carbon component far from the inlet end cannot be used evenly and rationally, and the activated carbon inside the activated carbon component near the inlet end needs to be replaced more frequently, affecting the effective utilization rate of the activated carbon component. Summary of the Invention

[0003] The core of this invention lies in solving the problem of low utilization rate of activated carbon components in existing technologies due to their location by repeatedly switching and guiding organic waste gas.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A high-efficiency activated carbon adsorption structure for treating organic waste gas includes an adsorption box set in an organic waste gas treatment system. An air inlet port and an air outlet port are respectively set at the left and right ends of the adsorption box. Assembly chambers are fixedly connected to the top and bottom of the adsorption box. The two assembly chambers are connected to the air inlet port at one end facing each other and to the air outlet port at the other end facing away from each other. An adsorption material placement assembly is placed inside the assembly chamber.

[0006] An air intake port is fixedly connected to the assembly chamber. The air intake port is provided with multiple air intake components arranged side by side at one end of the air intake port near the assembly chamber. The air intake components are composed of guide pipes fixed at both ends of the assembly chamber. Ventilation holes are evenly opened on the outside of the guide pipes. A drive ring is rotatably connected between two guide pipes. Guide baffles are fixedly connected to the left and right ends of the drive ring. The guide baffles slide in contact with the outer wall of the guide pipes, and the two guide baffles are staggered vertically.

[0007] Furthermore, the adsorption material placement assembly contains honeycomb activated carbon blocks and honeycomb zeolite blocks, with the honeycomb zeolite blocks laid at the bottom of the honeycomb activated carbon blocks.

[0008] Furthermore, a drive shaft is fixedly connected to the middle of the drive ring, the drive shaft extends in the direction of the air outlet port, a drive motor is fixedly connected to the outside of the air outlet port, and the output end of the drive motor is fixedly connected to the drive shaft.

[0009] Furthermore, a transmission gear ring is fixedly connected to the outside of the drive ring, and the transmission gear rings are connected to each other through chain meshing.

[0010] Optionally, the vent holes are rectangular, and adjacent vent holes are staggered and alternately arranged, with a filling brush fixedly connected to one end of the vent hole.

[0011] Furthermore, the inner wall of the guide baffle is provided with air suspension grooves at equal intervals, and the filling brush slides in contact with the air suspension grooves.

[0012] Furthermore, cleaning rods are fixedly connected to both the left and right ends of the drive ring, and cleaning brushes are fixedly connected to the outside of the cleaning rods. The cleaning brushes slide in contact with the inner wall of the guide tube.

[0013] Compared with the prior art, the advantages of this invention are:

[0014] This solution uses an air-gathering chamber to concentrate and collect the organic waste gas entering the adsorption box, which facilitates the entry of the organic waste gas into the air-expelling component. The organic waste gas entering the guide pipe diffuses evenly outward from the air vents, which facilitates the even dispersion of the organic waste gas into the assembly chamber. The honeycomb activated carbon block can efficiently purify organic waste gas and has significant advantages in purifying low-concentration organic waste gas.

[0015] The rotating drive ring drives two guide baffles to cyclically block the upper and lower surfaces of the guide tube, repeatedly switching the guidance of organic waste gas left and right. This further effectively improves the uniform diffusion effect of organic waste gas from left to right, effectively reduces the amount of organic waste gas adsorbed and treated by the adsorption material placement component closer to the air inlet, and ensures that the left and right ends of the adsorption material placement component adsorb and treat organic waste gas evenly. This also facilitates maintaining a consistent utilization rate of the honeycomb activated carbon blocks and honeycomb zeolite blocks inside the adsorption material placement component, and allows for the synchronous periodic replacement of the honeycomb activated carbon blocks and honeycomb zeolite blocks.

[0016] (2) When the guide pipe guides the organic waste gas, the waste gas in the guide pipe fills the air suspension tank through the air vent, which increases the air pressure inside the air suspension tank and realizes the air suspension state between the guide baffle and the guide pipe, effectively reducing the friction between the guide baffle and the guide pipe, and facilitating the rotation of the guide baffle on the outer wall of the guide pipe.

[0029] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0030] First implementation method:

[0031] Please see Figures 1 to 4A high-efficiency activated carbon adsorption structure for treating organic waste gas includes an adsorption box 1 disposed in an organic waste gas treatment system. The left and right ends of the adsorption box 1 are respectively configured as an inlet port 101 and an outlet port 102. Assembly chambers 103 are fixedly connected to the top and bottom of the adsorption box 1. The opposite ends of the two assembly chambers 103 are connected to the inlet port 101, and the opposite ends are connected to the outlet port 102. Organic waste gas enters the adsorption box 1 through the inlet port 101, passes through the assembly chambers 103, and is then discharged through the outlet port 102, completing the treatment of organic waste gas. For adsorption treatment, the adsorption material placement assembly 104 is placed inside the assembly chamber 103. The adsorption material placement assembly 104 contains honeycomb activated carbon blocks 105 and honeycomb zeolite blocks 106. The honeycomb zeolite blocks 106 are laid at the bottom of the honeycomb activated carbon blocks 105. The combination of honeycomb activated carbon blocks 105 and honeycomb zeolite blocks 106 forms a composite adsorption structure, which effectively improves the adsorption and purification capacity of organic waste gas. The structural strength of honeycomb zeolite blocks 106 is higher than that of honeycomb activated carbon blocks 105. The honeycomb activated carbon blocks 105 are stacked on top of honeycomb zeolite blocks 106, which effectively reduces the damage of honeycomb activated carbon blocks 105.

[0032] During the adsorption and purification treatment of organic waste gas, the organic waste gas enters the adsorption box 1 from the inlet port 101 and enters between the two assembly chambers 103, allowing the organic waste gas to pass through the assembly chambers 103. The adsorption material placement component 104 in the assembly chambers 103 adsorbs and purifies the organic waste gas. The purified organic waste gas is then discharged from the outlet port 102, completing the adsorption treatment process of organic waste gas. The honeycomb activated carbon block 105 can efficiently purify organic waste gas and has significant advantages for the purification of low-concentration organic waste gas. In particular, it has more significant advantages over other organic waste gas purification methods. At the same time, combined with the honeycomb zeolite block 106, the adsorption and purification capacity of organic waste gas is further effectively improved.

[0033] Please see Figures 5 to 7An air collection chamber 201 is fixedly connected between the air inlet 101 and the assembly chamber 103. Multiple air-guiding components are arranged side-by-side at one end of the air collection chamber 201 near the assembly chamber 103. The air collection chamber 201 concentrates the organic waste gas entering the adsorption box 1, facilitating its entry into the air-guiding components. The air-guiding components consist of guide pipes 202 fixed to both ends of the assembly chamber 103. Ventilation holes 203 are evenly distributed on the outside of the guide pipes 202, allowing the organic waste gas entering the guide pipes 202 to pass through the ventilation holes. The orifice 203 diffuses outwards evenly, facilitating the uniform dispersion of organic waste gas into the assembly chamber 103. A drive ring 204 is rotatably connected between the two guide pipes 202. Guide baffles 205 are fixedly connected to both ends of the drive ring 204. The guide baffles 205 slide in contact with the outer wall of the guide pipe 202, and the two guide baffles 205 are staggered vertically. The rotation of the drive ring 204 drives the two guide baffles 205 to cyclically block the upper and lower surfaces of the guide pipe 202, thus guiding the organic waste gas left and right. The repeated switching between right and left further effectively improves the uniform diffusion effect of organic waste gas, so that the left and right ends of the adsorption material placement component 104 can uniformly adsorb and treat organic waste gas. This makes it easier for the honeycomb activated carbon block 105 and honeycomb zeolite block 106 inside the adsorption material placement component 104 to maintain a consistent level of use, and facilitates the synchronous periodic replacement of the honeycomb activated carbon block 105 and honeycomb zeolite block 106. The drive shaft 206 is fixedly connected to the middle of the drive ring 204. The drive shaft 206 extends towards the outlet port 102. The drive motor 207 is fixedly connected to the outside of the outlet port 102. The output end of the drive motor 207 is fixedly connected to the drive shaft 206. The drive ring 204 is fixedly connected to the outside of the drive ring 204. The drive rings 208 are connected to each other by meshing transmission through the chain belt 209. The drive motor 207 drives the drive shaft 206 to realize the automatic rotation of the drive ring 204. The drive ring 204 is driven by the meshing transmission through the drive ring 208 and the chain belt 209, thereby realizing the synchronous rotation of the drive rings 204 arranged side by side.

[0034] When adsorbing and purifying organic waste gas in the adsorption chamber 1, the air collection chamber 201 concentrates the organic waste gas entering the adsorption chamber 1, facilitating its entry into the air intake assembly. The organic waste gas entering the guide pipe 202 diffuses evenly outward from the vent 203, ensuring uniform dispersion of the organic waste gas into the assembly chamber 103. The drive ring 204 rotates, driving two guide baffles 205 to cyclically block the upper and lower surfaces of the guide pipe 202, repeatedly switching the guidance of the organic waste gas left and right, further effectively improving the uniform diffusion of the organic waste gas from left to right. Specifically, when the guide baffle 205 blocks the vent 203 in the lower half of the guide tube 202, the organic waste gas is allowed to penetrate deeper into the lower half of the guide tube 202. This effectively reduces the amount of organic waste gas adsorbed and treated by the adsorption material placement component 104 in the area closer to the air inlet port 101, allowing the adsorption material placement component 104 to adsorb and treat the organic waste gas evenly. This ensures that the degree of use of the honeycomb activated carbon block 105 and the honeycomb zeolite block 106 remains consistent, thereby facilitating the synchronous periodic replacement of the honeycomb activated carbon block 105 and the honeycomb zeolite block 106.

[0035] Second implementation method:

[0036] Compared to the first embodiment, the main addition is an air suspension tank 3, the specific addition structure is as follows, and the rest of the structure is the same as the first embodiment.

[0037] Please see Figures 7 to 10 The vent holes 203 are rectangular in shape, and adjacent vent holes 203 are staggered and alternately arranged. A filling brush 301 is fixedly connected to one end of the vent hole 203. The filling brush 301 inside the vent hole 203 is also arranged in a staggered and alternately arranged state, which facilitates the filling brush 301 to thoroughly clean the inner wall of the guide baffle 205. The inner wall of the guide baffle 205 is provided with air suspension grooves 3 at equal intervals. The organic waste gas discharged from the vent holes 203 fills the air suspension grooves 3, which increases the air pressure inside the air suspension grooves 3 and realizes the air suspension state between the guide baffle 205 and the guide pipe 202. This effectively reduces the friction between the guide baffle 205 and the guide pipe 202 and facilitates the rotation of the guide baffle 205 on the outer wall of the guide pipe 202. The filling brush 301 slides in contact with the air suspension tank 3. While cleaning the air suspension tank 3, the filling brush 301 also blocks both ends of the air suspension tank 3, effectively preventing the organic waste gas in the air suspension tank 3 from being discharged, further enhancing the air suspension effect between the guide baffle 205 and the guide tube 202. The left and right ends of the drive ring 204 are fixedly connected to the cleaning rod 302, and the outside of the cleaning rod 302 is fixedly connected to the cleaning brush 303. The cleaning brush 303 slides in contact with the inner wall of the guide tube 202. The cleaning rod 302 uses the cleaning brush 303 to clean the inner wall of the guide tube 202, sweeping the dust on the inner wall of the guide tube 202 into the vent hole 203, effectively preventing dust from accumulating on the inner wall of the guide tube 202.

[0038] Compared to the first embodiment, when the guide pipe 202 guides the organic waste gas, the organic waste gas in the guide pipe 202 fills the air inlet suspension trough 3 through the air vent 203, which increases the air pressure inside the air suspension trough 3 and forms an air suspension between the guide baffle 205 and the guide pipe 202, effectively reducing the friction between the guide baffle 205 and the guide pipe 202, and facilitating the rotation of the guide baffle 205 on the outer wall of the guide pipe 202.

[0039] During the rotation of the drive ring 204, the cleaning rod 302 is driven synchronously. The cleaning rod 302 uses the cleaning brush 303 to clean the inner wall of the guide tube 202, sweeping the dust on the inner wall of the guide tube 202 into the vent hole 203, effectively preventing dust from accumulating on the inner wall of the guide tube 202.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
