Description

Technical Field

[0001] This invention relates to the field of waste gas purification, and more specifically, to a comprehensive purification and degradation treatment system for lithium battery tar-containing waste gas. Background Technology

[0002] The production and manufacturing of lithium batteries inevitably generates waste gas, wastewater, and waste residue. Previously, the lack of understanding of the stages in the lithium battery industry that might generate waste gas led to a series of problems in waste gas treatment, especially VOCs treatment. Now, tar-containing waste gas generated during the production of lithium battery materials can be purified and degraded through processes such as pretreatment + activated carbon adsorption-desorption + catalytic combustion, pretreatment + activated carbon adsorption-desorption + condensation recovery, and pretreatment + rotary adsorption-desorption + catalytic combustion.

[0003] Among the VOCs waste gas treatment technologies, activated carbon adsorption is suitable for purifying VOCs with low water and dust content and medium to low concentrations. It has a high removal rate and is easy to automate, making it the most widely used and simplest treatment process. A typical "primary adsorption-desorption" method involves first passing the mixed gas containing VOCs through a pretreatment system (such as condensation, absorption, and filtration) to remove water vapor, corrosive substances, and particulate matter from the waste gas, preventing corrosion of end equipment and blockage of the adsorbent, while reducing the end load. The pressure is then adjusted by a pressure regulator before entering the adsorption bed for adsorption purification. The pollutants in the waste gas are adsorbed onto the activated carbon in the adsorption bed. After the purified gas meets the standards, it can be discharged into the atmosphere at high altitude.

[0004] Chinese patent CN117138523B discloses a VOCs removal device for VOCs waste gas treatment technology. Through a steam pipe, multiple steam distribution pipes, and multiple steam outlet pipes, low-pressure steam can be simultaneously delivered into multiple steam outlet holes. The steam is guided by the steam outlet holes and disperses in both vertical and horizontal directions, that is, steam can be sprayed onto both the upper and lower mesh frames at the same time. At the same time, through a rotation drive mechanism, multiple mesh frames in multiple adsorption frames can be driven to rotate synchronously, so that the activated carbon blocks in the mesh frames are evenly and comprehensively in contact with the steam during rotation, and the high-temperature desorption effect of the steam is relatively uniform and thorough.

[0005] To address the aforementioned issues, existing technologies offer solutions, but these solutions increase the contact between the activated carbon blocks and the gas through rotation. While this increases gas flow, the gap between the activated carbon blocks and the mesh frame during rotation means that some gas still flows between them, resulting in gas not being processed by the activated carbon blocks and thus affecting the quality of gas treatment. Summary of the Invention

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide a comprehensive purification and degradation treatment system for lithium battery tar-containing waste gas.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A comprehensive purification and degradation treatment system for lithium battery tar-containing waste gas includes a treatment box body. A purification mechanism is installed inside the treatment box body to filter and remove tar from the waste gas. The purification mechanism includes multiple activated carbon plates that slide inside the treatment box body. A transmission rod is fixedly installed on the upper surface of each of the activated carbon plates, and a transmission plate is fixedly installed at the top of each transmission rod. A first electric telescopic rod is fixedly installed on the surface of the treatment box body, and a sealing box is fixedly installed on the upper surface of the treatment box body. An air inlet pipe is slidably connected inside the sealing box, and an air inlet hood is fixedly installed at one end of the air inlet pipe. Air inlet holes are evenly distributed on the top of the treatment box body.

[0009] Furthermore, the purification mechanism also includes a support plate fixed to one side of the upper surface of the sealed box. The support plate has a threaded rod internally connected to it. One end of the threaded rod is rotatably connected to a moving plate, and the other end of the threaded rod is equipped with a rotating motor. A limit block is fixedly installed on the outer circumference of the rotating motor. A limit groove is formed on the upper surface of the sealed box. A first one-way valve is fixedly installed inside the air inlet. A linkage block is fixedly installed at the output end of the first electric telescopic rod. Multiple partition plates are fixedly installed inside the main body of the treatment box. Multiple partition tubes are fixedly installed on the lower surface of the main body of the treatment box. A solenoid valve is fixedly installed at one end of each of the partition tubes, and an exhaust pipe is fixedly installed at one end of each of the partition tubes. A sealing assembly is provided inside the activated carbon plate.

[0010] Furthermore, the partition plates are evenly distributed, the surface of the activated carbon plate is slidably connected to the surface of the partition plates, and the output end of the first electric telescopic rod is connected to the transmission plate through a linkage block.

[0011] Furthermore, the transmission rod slides through the interior of the processing box body, the transmission plate is located above the processing box body, and the processing box body is connected to the sealed box through the first one-way valve.

[0012] Furthermore, the bottom end of the limiting block is located inside the limiting groove, and the surface of the limiting block is slidably connected to the inner surface of the limiting groove, while one end of the moving plate is fixedly connected to the surface of the air intake pipe.

[0013] Furthermore, the sealing assembly includes an installation groove formed inside the activated carbon plate, a second electric telescopic rod is fixedly installed inside the installation groove, a sliding groove is formed inside the activated carbon plate, a plurality of sealing plates are slidably connected inside the sliding groove, and a connecting rod is fixedly installed on each adjacent side of the plurality of sealing plates.

[0014] Furthermore, the multiple sealing plates are equidistantly distributed, and the connecting rod does not contact the sliding groove.

[0015] Furthermore, the mounting groove and the sliding groove are interconnected, and the output end of the second electric telescopic rod is fixedly connected to the surface of the sealing plate.

[0016] Furthermore, the air intake shroud is provided with a pushing mechanism, which includes a pushing cylinder fixed to the upper surface of the air intake shroud. A pushing rod is slidably connected inside the pushing cylinder. A pushing spring is fixedly installed at one end of the pushing rod inside the pushing cylinder. A third electric telescopic rod is fixedly installed at the bottom end of the pushing spring. A trigger switch is fixedly installed on the upper surface inside the sealed box and above the air intake hole.

[0017] Furthermore, the electric telescopic rod is fixedly installed at the bottom of the push cylinder, and multiple trigger switches are provided, which are located directly above multiple air inlets, with each trigger switch corresponding to one of the air inlets.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) This solution sets up a purification mechanism. When the gas is processed, the gas is transported into the interior of the processing box and then squeezed by the up-and-down moving activated carbon plate. This increases the gas flow and ensures that the air passes through the interior of the activated carbon plate to the maximum extent, thereby improving the quality of gas treatment and optimizing the gas filtration and removal effect. Furthermore, the solution adopts a zoned treatment, with multiple zones being treated separately and simultaneously. This increases the processing speed and the gas treatment time, further optimizing the quality of gas treatment.

[0020] (2) By setting up a sealing component, this solution can isolate the gas on both sides of the activated carbon plate after the gas is treated, reduce the mutual exchange of gases, prevent untreated gas from being pushed out through the activated carbon plate, and thus affect the quality of gas treatment. Furthermore, it can push out all the treated gas, reduce the residue of the treated gas, and improve the speed of gas treatment. Attached Figure Description

[0031] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 A comprehensive purification and degradation treatment system for lithium battery tar-containing waste gas includes a treatment box body 1, and a purification mechanism 2 is provided inside the treatment box body 1. The purification mechanism 2 is used to filter and remove tar from the waste gas.

[0033] The purification mechanism 2 includes multiple activated carbon plates 21 that slide inside the treatment box body 1. A transmission rod 22 is fixedly installed on the upper surface of each of the multiple activated carbon plates 21. A transmission plate 23 is fixedly installed at the top of each of the multiple transmission rods 22. A first electric telescopic rod 24 is fixedly installed on the surface of the treatment box body 1. A sealing box 25 is fixedly installed on the upper surface of the treatment box body 1. An air inlet pipe 26 is slidably connected inside the sealing box 25. An air inlet hood 27 is fixedly installed at one end of the air inlet pipe 26. Air inlet holes 28 are evenly opened on the top of the treatment box body 1.

[0034] like Figures 1-5 As shown, the purification mechanism 2 also includes a support plate 210 fixed to one side of the upper surface of the sealed box 25. The support plate 210 is internally threaded with a threaded rod 211. One end of the threaded rod 211 is rotatably connected to a moving plate 212, and the other end of the threaded rod 211 is provided with a rotating motor 213. A limit block 214 is fixedly installed on the outer circular surface of the rotating motor 213. A limit groove 215 is opened on the upper surface of the sealed box 25. A first one-way valve 216 is fixedly installed inside the air inlet 28. A linkage block 217 is fixedly installed at the output end of the first electric telescopic rod 24. Multiple partition plates 218 are fixedly installed inside the treatment box body 1. Multiple partition pipes 219 are fixedly installed on the lower surface of the treatment box body 1. A solenoid valve 220 is fixedly installed at one end of each of the multiple partition pipes 219, and an exhaust pipe 221 is fixedly installed at one end of each of the multiple partition pipes 219. A sealing assembly 29 is provided inside the activated carbon plate 21.

[0035] It should be noted that since the support plate 210 is fixed to the surface of the sealing box 25, and the threaded rod 211 is threadedly connected to the support plate 210, when the threaded rod 211 rotates, the support plate 210, which is threadedly connected to the threaded rod 211, will cause the threaded rod 211 to move. In order to enable the rotating motor 213 to drive the threaded rod 211 to rotate and prevent the rotating motor 213 from rotating on its own at one end of the threaded rod 211, the rotation of the main body of the rotating motor 213 is restricted by the setting of the limiting groove 215 and the limiting block 214. Since the threaded rod 211 needs to move under the drive of the output end of the rotating motor 213, the limiting groove 215 and the limiting block 214 can restrict the rotation of the rotating motor 213 while also allowing the rotating motor 213 to move freely.

[0036] like Figures 1-5As shown, the partition plates 218 are evenly distributed, the surface of the activated carbon plate 21 is slidably connected to the surface of the partition plates 218, and the output end of the first electric telescopic rod 24 is connected to the transmission plate 23 through the linkage block 217.

[0037] It should be noted that the movable plate 212 rotatably connected to one end of the threaded rod 211 is to prevent the movable plate 212 from rotating synchronously when the threaded rod 211 rotates. It is known that the threaded rod 211 will move under the action of the support plate 210 when it rotates. Therefore, when the threaded rod 211 moves, it will drive the movable plate 212 to move, thereby driving the intake pipe 26 to move synchronously.

[0038] like Figures 1-5 As shown, the transmission rod 22 slides through the interior of the processing box body 1, the transmission plate 23 is located above the processing box body 1, and the processing box body 1 is connected to the sealing box 25 through the first one-way valve 216.

[0039] It is worth noting that due to the use of a segmented treatment, after the gas is added to one area, the gas in that area will continue to be treated by the activated carbon plate 21 while the remaining gas is being added, thereby increasing the gas treatment time.

[0040] It is worth noting that since the air intake hood 27 uses a movable air supply, it is easy for the air intake hood 27 and the sealing box 25 to have poor sealing and air leakage. This can be improved by installing a retractable retractable rod with an internal retractable spring on the top of the air intake hood 27, using the elasticity of the retractable spring to push the connection between the air intake hood 27 and the sealing box 25 more tightly, or by installing sealing gaskets around the air intake hole 28 at the bottom of the sealing box 25 to further improve its sealing effect.

[0041] like Figures 1-5 As shown, the bottom end of the limiting block 214 is located inside the limiting groove 215, and the surface of the limiting block 214 is slidably connected to the inner surface of the limiting groove 215. One end of the moving plate 212 is fixedly connected to the surface of the air intake pipe 26.

[0042] Understandably, under the action of the limiting block 214 and the limiting groove 215, the rotating motor 213 is restricted from rotating with the rotating shaft, while the rotating motor 213 can also be translated.

[0043] In the actual process of treating waste gas, it is necessary to ensure that the activated carbon plate 21 makes full contact with the VOCs gas in the waste gas to achieve the filtration and removal of VOCs gas. However, simply rotating the plate does not allow the gas to completely pass through the activated carbon plate 21, and the gas flow is generally poor, resulting in ineffective filtration and removal. Therefore, a purification mechanism 2 is set up. When VOCs gas needs to be treated, the output end of the first electric telescopic rod 24 and the rotating motor 213 are controlled to operate. The operation of the rotating motor 213 causes the output end of the rotating motor 213 to rotate, which in turn drives the threaded rod 211 to rotate. The rotation of the threaded rod 211 causes the threaded rod 211 to move, which in turn drives the moving plate 212 to move. The movement of 212 will cause the air intake pipe 26 to move, and the movement of the air intake pipe 26 will cause the air intake hood 27 to move. When the air intake hood 27 moves above the air intake hole 28, the gas inside the air intake pipe 26 can enter the interior of the processing box body 1 through the air intake hood 27 and the air intake hole 28. After the gas enters the interior of the processing box body 1, the output end of the first electric telescopic rod 24 reciprocates, causing the output end of the first electric telescopic rod 24 to drive the transmission plate 23 and the transmission rod 22 to move up and down. The up and down movement of the transmission rod 22 will drive the activated carbon plate 21 to move up and down, and then the up and down moving activated carbon plate 21 will squeeze the gas inside the processing box body 1, so that the gas flows through the holes inside the activated carbon plate 21 when it is squeezed. Under the condition of ensuring that the gas is fully combined with the activated carbon plate 21, the gas flow is increased.

[0044] It should be noted that when gas is supplied to the interior of the treatment chamber 1, the activated carbon plate 21 is at the highest point of the treatment chamber 1. When air is supplied to the interior, the activated carbon plate 21 slowly descends. At the same time, the solenoid valve 220 opens, so that the gas below the activated carbon plate 21 can flow through the separator pipe 219 to the interior of the exhaust pipe 221 under the pushing action of the activated carbon plate 21 and the continuous supply of gas to the interior of the treatment chamber 1, and then flow through the exhaust pipe 221 to the subsequent treatment process.

[0045] It is worth noting that the output end of the rotary motor 213 can rotate reciprocally, which can drive the air intake shroud 27 to move reciprocally. When the air intake shroud 27 moves above the air intake hole 28, the rotary motor 213 needs to stop briefly because continuous air supply is required. After the gas supply is completed, it can resume operation. Since the gas is processed in a segmented manner, the process of gas supply is also the process of discharging the processed gas. In order to avoid the gas that has just entered being discharged when it is at one end, the rotary motor 213 needs to supply gas when it moves in one direction at a normal speed. When the rotary motor 213 returns to its original position, its speed is faster and it no longer supplies gas.

[0046] like Figure 6 As shown, the sealing assembly 29 includes an installation groove 291 opened inside the activated carbon plate 21. A second electric telescopic rod 292 is fixedly installed inside the installation groove 291. A sliding groove 293 is opened inside the activated carbon plate 21. Multiple sealing plates 294 are slidably connected inside the sliding groove 293. A connecting rod 295 is fixedly installed on each adjacent side of the multiple sealing plates 294.

[0047] like Figure 6 As shown, multiple sealing plates 294 are equidistantly distributed, and the connecting rod 295 does not contact the sliding groove 293.

[0048] like Figure 6 As shown, the mounting groove 291 and the sliding groove 293 are interconnected, and the output end of the second electric telescopic rod 292 is fixedly connected to the surface of the sealing plate 294.

[0049] In practical use, to avoid the exchange between treated and untreated gas during the above process, which would lead to poor gas treatment effect, a sealing component 29 is set up. When the air inlet hood 27 moves above an air inlet 28, the second electric telescopic rod 292 inside the activated carbon plate 21 below the air inlet 28 operates. The output end of the second electric telescopic rod 292 pushes the sealing plate 294, and under the action of the connecting rod 295, multiple sealing plates 294 move synchronously. The multiple sealing plates 294 seal the filter holes inside the activated carbon plate 21, so that when untreated gas is delivered into the treatment box body 1, the untreated gas and the treated gas can be isolated to prevent gas exchange. At the same time, the treated gas can be pushed out through the activated carbon plate 21, further improving the gas treatment efficiency.

[0050] like Figure 4 , Figure 7 and Figure 8As shown, a pushing mechanism 3 is provided on the air intake hood 27. The pushing mechanism 3 includes a pushing cylinder 31 fixed to the upper surface of the air intake hood 27. A pushing rod 32 is slidably connected inside the pushing cylinder 31. A pushing spring 33 is fixedly installed at one end of the pushing rod 32 inside the pushing cylinder 31. A third electric telescopic rod 34 is fixedly installed at the bottom end of the pushing spring 33. A trigger switch 35 is fixedly installed on the upper surface inside the sealed box 25 and above the air intake hole 28.

[0051] like Figure 4 , Figure 7 and Figure 8 As shown, the third electric telescopic rod 34 is fixedly installed at the bottom of the push cylinder 31. There are multiple trigger switches 35, which are located directly above the multiple air inlets 28, and each trigger switch 35 corresponds to one air inlet 28.

[0052] In actual use, due to insufficient contact between the air intake hood 27 and the sealing box 25, gas may leak from the connection between them. Therefore, a pushing mechanism 3 is provided. When the air intake hood 27 moves, it drives the pushing cylinder 31 to move, which in turn drives the pushing rod 32. When the air intake hood 27 moves above the air intake hole 28, the pushing rod 32 is directly below and in contact with the trigger switch 35. The trigger switch 35 then controls the output end of the third electric telescopic rod 34 to move upwards. This upward movement of the third electric telescopic rod 34 compresses the pushing spring 33, causing it to contract. This contraction increases the upward pushing force of the pushing spring 33, which in turn increases the downward reaction force. Under the action of this reaction force, the air intake hood 27 and the sealing box 25 are brought into close contact, thus reducing gas leakage.

[0053] It is worth noting that when the rotating motor 213 is running, no gas enters the interior of the air intake hood 27 through its air intake pipe 26. Furthermore, when the rotating motor 213 is running, the third electric telescopic rod 34 is in a retracted state. Even when the third electric telescopic rod 34 is in a retracted state, its height relative to the push spring 33 will cause one end of the push rod 32 to contact the trigger switch 35 or the upper surface inside the sealing box 25, although the contact force is relatively small. When the rotating motor 213 stops moving and the push rod 32 contacts the trigger switch 35, the output end of the third electric telescopic rod 34 will move upwards. When the rotating motor 213 starts running again, the third electric telescopic rod 34 will automatically retract. A sealing ring is provided on the lower surface of the air intake hood 27, which, under the action of the reaction force, further increases the contact force between the air intake hood 27 and the sealing box 25, increasing the sealing performance between them. When the air intake hood 27 moves, since the air intake hood 27 is not pushed by any force, the sealing ring at the bottom of the air intake hood 27 will not generate much resistance to its movement.

[0054] The above description is merely a preferred embodiment of the present invention; however, 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 its improved concepts, should be covered within the scope of protection of the present invention.
