Technical Field

[0001] The present invention relates to the technical field of industrial waste gas treatment, and in particular to an industrial waste gas treatment device and a use method thereof. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during the production process of an enterprise's factory. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have an accumulation effect, which will more seriously endanger human health. Different substances will have different effects. Industrial waste gas treatment refers to the pretreatment of waste gas generated by industrial sites such as factories and workshops before external discharge to meet national standards for external waste gas emissions. The application prospects of activated carbon in industrial exhaust gas purification are still broad. With the advancement of technology, the development of functional activated carbon has enabled it to exhibit better adsorption performance when dealing with more complex exhaust gas components. At the same time, the combination of activated carbon and other treatment technologies can also effectively overcome its limitations and improve the purification effect.

[0003] In the future, with increasingly stringent environmental regulations and companies' emphasis on sustainable development, the application of activated carbon in industrial tail gas treatment will continue to grow. By optimizing adsorption materials and process flows, activated carbon is expected to continue to play an important role under more stringent tail gas emission standards. From a professional perspective, activated carbon is indeed useful in industrial tail gas purification, especially in the treatment of organic waste gas and odorous gases. However, for the treatment of certain high-concentration pollutants or specific gases, the effect of activated carbon is limited and needs to be combined with other technologies to achieve the ideal purification effect. With the advancement of technology and the improvement of environmental protection requirements, the application of activated carbon in industrial tail gas purification will be more extensive and efficient.

The beneficial effect of the present invention is that the waste gas can be desorbed and catalytically purified at a normal temperature of 35 degrees, which improves the safety of waste gas treatment, saves costs, and can be circulated and reciprocated to treat the waste gas without secondary pollution.

[0005] The existing industrial waste gas treatment device uses adsorption materials to adsorb toxic and harmful substances in the waste gas. When the adsorption saturation of the adsorption material reaches the set conditions, the exhaust fan needs to be turned off first. The exhaust fan can only be turned on and the adsorption material can be used again after the desorption of the adsorption material is completed. The entire adsorption process has a waiting interval time, and the adsorption purification operation is not continuous and efficient. In view of the above problems, the existing equipment needs to be improved. Summary of the invention

Connect the air intake pipe 14 and the exhaust pipe together, pass the exhaust gas into the air intake pipe 14, and the exhaust gas flows downward. The activated carbon 23 at the bottom first adsorbs hydrocarbons in the exhaust gas. After the activated carbon 23 is saturated with adsorption, the first bevel gear 2203 rotates, the second bevel gear 2204, the rotating shaft 2205 and the two rotating disks 2206 rotate as a whole, the circular gear 2227 and the screw rod 2226 at the top rotate, the upper card seat 2229 moves right, the corresponding moving rod 2215 moves right, and the other moving rod 2215 on the rotating plate 2211 moves left. The two first pistons 2216 approach each other, the upper and lower second pistons 2220 move away from each other, and the sealing ring 2221 leaves the third intermediate cylinder 2230, thereby unlocking the two upper third intermediate cylinders 2230; S2. After unlocking the two third intermediate cylinders 2230 at the top, the upper rotating disk 2206 rotates to drive the corresponding rotating plate 2211 to rotate 180 degrees, thereby exchanging the positions of the two third intermediate cylinders 2230; S3. After the positions of the two upper third intermediate cylinders 2230 are exchanged, the circular gear 2227 and the screw rod 2226 rotate, the two first pistons 2216 approach each other, the upper and lower second pistons 2220 approach each other, and the sealing ring 2221 reseals and locks the two upper third intermediate cylinders 2230; S4, rotating the direction of the rotary valve 16, and then using the upper activated carbon 23 to continue to adsorb hydrocarbons in the exhaust gas, while passing hot air into the first top frame 3 to desorb and regenerate the saturated activated carbon 23 below and burn the desorbed gas; S5. Alternately use two activated carbons 23 to continuously adsorb hydrocarbons in the exhaust gas.

[0035] The working principle of the device is as follows: first, the air intake pipe 14 is connected with the exhaust pipe, and the exhaust gas enters the second intermediate cylinder 13 through the air intake pipe 14. The rotary valve 16 tilts to the left at the beginning, and the exhaust gas flows downward and enters the second bottom frame 18. Two rotating plates 2211 are provided, and the two rotating plates 2211 are distributed up and down. Each rotating plate 2211 corresponds to an activated carbon 23. First, the activated carbon 23 corresponding to the lower rotating plate 2211 is used to adsorb hydrocarbon components in the organic waste gas. The waste gas after adsorption is discharged through the second exhaust pipe 19 on the second bottom frame 18. When the amount of hydrocarbons adsorbed by the activated carbon 23 is close to its designed saturation value, the first bevel gear 2203 rotates to drive the second bevel gear 2204 to rotate, and the rotating plate 2211 rotates to rotate. The shaft 2205 and the turntable 2206 rotate, and the first toothed plate 2208 on the turntable 2206 at the top of the shaft 2205 is initially meshed and connected with the corresponding circular gear 2227. The rotation of the circular gear 2227 drives the corresponding screw rod 2226 to rotate, and the corresponding card seat 2229, the moving rod 2215, the first piston 2216 and the third piston 2224 move right as a whole, and another third piston 2224, the moving rod 2215 and the first piston 2216 on the same turntable 2211 move left as a whole, and the two sets of second pistons 2220 on the same support ring 2217 move away from each other, and the corresponding two sealing rings 2221 move away from each other, so as to unlock the two third intermediate cylinders 2230 above, and the first toothed plate 2208 leaves the circular gear. After that, the rack 2207 is meshed and connected with the corresponding gear ring 2212, and the rotation of the turntable 2206 drives the gear ring 2212 to rotate, thereby driving the upper rotating plate 2211 to rotate 180 degrees, thereby realizing the exchange of the positions of the two third intermediate cylinders 2230 on the rotating plate 2211. After the rack 2207 leaves the gear ring 2212, the second gear plate 2209 is meshed and connected with the circular gear 2227, the circular gear 2227 and the screw rod 2226 rotate, the card seat 2229 moves back, and the two groups of second pistons 2220 on the same support ring 2217 approach each other, so as to re-seal and lock the third intermediate cylinder 2230. After the second gear plate 2209 leaves the circular gear 2227, the arc-shaped locking plate 2210 is stuck between the two convex The activated carbon 23 corresponding to the upper rotating plate 2211 continues to adsorb hydrocarbons in the exhaust gas, and the exhaust gas after adsorption is discharged through the second exhaust pipe 19 on the second top frame 17, so as to achieve the effect of alternating adsorption of the two activated carbons 23. Since the positions of the racks 2207 on the two rotating disks 2206 are staggered, and the positions of the first tooth plate 2208, the second tooth plate 2209 and the arc-shaped locking plate 2210 on the two rotating disks 2206 are different, when one of the circular gears 2227 rotates, the other circular gear 2227 is locked by the corresponding arc-shaped locking plate 2210.When the rack 2207 on one of the turntables 2206 is meshed and connected with the corresponding gear ring 2212, the rack 2207 on the other turntable 2206 is not meshed and connected with the corresponding gear ring 2212. Therefore, when one of the rotating plates 2211 rotates, the other rotating plate 2211 does not rotate. After one of the rotating plates 2211 has completed its rotation and rotated the rotating valve 16, the other rotating plate 2211 rotates again, which is convenient for turning the adsorption saturated activated carbon 23 to the left. At the beginning, the air pump 10 draws external hot air into the exhaust pipe 11, and the hot air enters the first top frame 3. The hot air desorbs the activated carbon 23. An electronic ignition component is provided in the air storage box 7. The desorbed gas enters the air storage box 7 through the outlet pipe 6 and the jet channel 8 and burns. The heat of combustion can heat the exhaust pipe 11, and then the normal temperature gas can be supplied to the exhaust pipe 11. The first exhaust pipe 9 can be used for exhaust.
