Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for the production of nonwoven bags. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is called cloth because it resembles the appearance and some properties of fabric. Nonwoven fabrics are characterized by moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. For example, they are often made from polypropylene granules as raw material, produced through a continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing.

[0003] Chinese Patent Publication No. CN213375957U discloses a waste gas treatment device for non-woven bag production equipment, including an exhaust pipe and a water tank. The water tank is located on the side of the exhaust pipe, and an exhaust head is fixedly connected to the bottom of the exhaust pipe. A first filter box and a first connecting pipe are fixedly connected to one end of the exhaust pipe. A connecting groove is opened at the bottom of the first filter box, and a filter is fixedly connected to the first filter box through the connecting groove. A filter screen is fixedly connected to the upper end of the filter. Compared with existing ordinary non-woven waste gas treatment devices, this waste gas treatment device for non-woven bag production equipment achieves sufficient contact between activated carbon and waste gas by connecting multiple second connecting pipes to the first connecting pipe. By setting up the first filter box, dust and other impurities mixed in with the waste gas fall into the filter under the spray of the nozzle and do not enter the second filter box and adhere to the activated carbon. However, the above patent still has the following defects: The aforementioned patent documents only remove impurities through spraying and single-stage filtration. The contact between the exhaust gas and the treatment medium is insufficient, making it difficult to completely remove harmful components. The lack of targeted cooling and diversion design results in limited purification efficiency. The absence of an automatic particle shedding and centralized collection mechanism makes it easy for impurities to adhere and cause blockages, affecting the continuous operation of the equipment. The overall treatment process is simple and cannot achieve graded removal of harmful components, making it difficult to guarantee the cleanliness of the discharged gas. Summary of the Invention

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, please refer to Figure 1 , Figure 2 as well as Figure 3As shown, a waste gas treatment device for non-woven bag production includes a conveying pipe 1, which is connected to an external non-woven bag production device to ensure that the waste gas generated during the production process can be directly introduced into the device to provide a stable gas source for subsequent treatment. A treatment mechanism 2 is fixedly connected to the other side of the conveying pipe 1, which can realize the acid-base adjustment and temperature reduction of the waste gas. A dehumidification and filtration mechanism 5 is fixedly connected to the right side of the treatment mechanism 2. The dehumidification and filtration mechanism 5 is used to further adsorb and purify the pre-treated waste gas, remove residual harmful gases, and improve the purity of the waste gas purification. A cooperating mechanism 4 is fixedly connected to the middle right side of the dehumidification filter mechanism 5. The cooperating mechanism 4 mainly plays the role of assisting particle collection and guiding transmission, ensuring that the exhaust gas smoothly enters the subsequent treatment stage, and realizing the centralized recovery of particles to reduce waste pollution. A second treatment mechanism 3 is fixedly connected to the rear of the dehumidification filter mechanism 5. The second treatment mechanism 3 is used to perform final particle capture on the exhaust gas after adsorption, further removing fine impurities in the exhaust gas, improving the exhaust gas purification effect, and ensuring that the discharged gas meets environmental protection standards. A collection box 6 is fixedly connected to the rear of the first treatment mechanism 2. The first treatment mechanism 2 includes a first treatment shell 21. The bottom of the inner cavity of the first treatment shell 21 is fixedly connected to... A U-shaped plate 23 is connected to the waste gas. The U-shaped plate 23 can limit and contain the mixed solution of ethylene glycol and sodium hydroxide, preventing the solution from flowing freely and ensuring that the waste gas can fully contact and react with the solution, thereby improving the neutralization treatment efficiency. A connecting rod 24 is rotatably connected to the middle of the U-shaped plate 23. The connecting rod 24 can drive the external structure to rotate, thereby compressing and guiding the waste gas, slowing down the upward speed of the waste gas, and extending the reaction time. A hollow spiral plate 25 is fixedly connected to the outer surface of the connecting rod 24. The hollow spiral plate 25 can not only slow down the upward speed of the waste gas and increase the waste gas treatment time, but also provide secondary cooling of the waste gas through the internal flowing solution, further improving the waste gas cooling effect.

[0021] It should be further noted that the ethylene glycol and sodium hydroxide mixed solution mentioned above is a conventional technical means in the prior art, including but not limited to the ethylene glycol and sodium hydroxide mixed solution, the triethylene glycol and sodium hydroxide mixed solution, and the propylene glycol and sodium hydroxide mixed solution. In this solution, any solution that can neutralize the acidic gas in the waste gas while withstanding cooling and maintaining the original chemical reaction is acceptable. Furthermore, regardless of the type of alcohol solvent used, the amount of sodium hydroxide added should not be too high, otherwise it will cause the solution viscosity to rise sharply, affecting the circulation efficiency of the water pump. It is recommended to control the pH value between 8 and 10.

[0022] Please see Figure 3As shown, the bottom of the inner cavity of the treatment shell 21 contains a mixed solution of ethylene glycol and sodium hydroxide. This mixed solution can undergo an acid-base neutralization reaction with the waste gas, efficiently removing acidic harmful components such as organic acids and acidic gases from the waste gas, thus improving the basic purification effect of the waste gas. A reflux assembly 22 is fixedly connected to the left side of the treatment shell 21. The reflux assembly 22 can realize the circulation and cooling of the mixed solution, ensuring that the solution is always in the optimal treatment state, ensuring the stability of the treatment effect, and avoiding the decrease in neutralization efficiency due to the increase in solution temperature or the decrease in concentration. A guide block 27 is fixedly connected to the top of the inner cavity of the treatment shell 21. The guide block 27 has a specific inclined structure, which can guide the flow of the neutralized and cooled solution. The exhaust gas is guided to ensure that it enters the dehumidification and filtration mechanism 5 smoothly, preventing it from stagnating in the treatment shell 21. A hollow disk 26 is fixedly connected to the bottom of the guide block 27. The hollow disk 26 is an intermediate carrier for the circulation and transmission of the mixed solution. It can distribute the cooled solution to the output rod 283 and the hollow spiral plate 25 to ensure uniform solution distribution. An output mechanism 28 is fixedly connected to the upper end of the guide block 27. The output mechanism 28 can drive the connecting rod 24 to rotate to compress and guide the exhaust gas, and can also drive the internal structure of the treatment mechanism 3 through transmission. This achieves multi-structure collaborative drive of a single power source, reduces energy consumption of the device, and improves operational stability.

[0023] For further details, please refer to Figure 4 and Figure 5 As shown, the reflux assembly 22 includes an input pipe 221, which draws out the solution and delivers it to the cooling structure. The input pipe 221 is fixedly connected to the side wall of the delivery pipe 1. The stability of the delivery pipe 1 enhances the installation stability of the input pipe 221, preventing displacement during solution transport and ensuring the continuity of solution delivery. A fixing block 222 is fixedly connected to the left side of the processing housing 21. The fixing block 222 is used to install and fix the semiconductor cooling plate 223, and also provides support and positioning for the input pipe 221, ensuring a tight fit between the input pipe 221 and the semiconductor cooling plate 223. The middle left side of the fixing block 222 is fixedly connected to the input pipe 221, further enhancing the connection stability of the input pipe 221 and preventing it from loosening during use. A semiconductor cooling plate 223 is fixedly connected to the left side of block 222. The semiconductor cooling plate 223 can quickly absorb heat from the solution to achieve efficient cooling of the solution and ensure the neutralization reaction efficiency. A heat dissipation fin 224 is fixedly connected to the left side of the semiconductor cooling plate 223. The heat dissipation fin 224 can quickly dissipate the heat absorbed by the semiconductor cooling plate 223 to the outside, preventing the semiconductor cooling plate 223 from reducing its cooling efficiency due to overheating and extending its service life. A water pump 225 is fixedly connected to the other end of the input pipe 221. An input pipe 226 is fixedly connected to the output end of the water pump 225. The input pipe 226 is the channel for transporting the cooled mixed solution to the hollow disk 26 so that the solution can be reused and the processing cost can be reduced.

[0024] like Figure 5 As shown, a gap exists between the semiconductor cooling plate 223 and the fixing block 222 to store and fix the input pipe 221. This gap ensures stable installation of the input pipe 221 while allowing the semiconductor cooling plate 223 to fully contact the input pipe 221, increasing the heat exchange area, ensuring cooling effect, preventing uneven cooling due to displacement of the input pipe 221, improving the stability and uniformity of solution cooling, and ensuring the consistency of subsequent neutralization reactions. The heat dissipation fins 224 are used to cool one side of the semiconductor cooling plate 223. Their multi-fin structure increases the heat dissipation area, quickly dissipating the heat generated by the semiconductor cooling plate 223 during operation, preventing it from reducing cooling efficiency due to overheating, extending the service life of the semiconductor cooling plate 223, and reducing device maintenance costs. The other end of the input pipe 226 communicates with the inner cavity of the hollow disk 26, ensuring that the cooled mixed solution smoothly enters the hollow disk 26, providing a guarantee for the uniform flow of the solution in the hollow spiral plate 25, realizing secondary cooling treatment of the waste gas by the solution, further reducing the waste gas temperature, and facilitating subsequent adsorption and purification.

[0025] like Figure 4 As shown, the output mechanism 28 includes a motor 281. The output end of the motor 281 is fixedly connected to an output rod 283 via a coupling. A transmission belt 282 is wound around the upper part of the outer surface of the output rod 283. The transmission belt 282 can efficiently transmit the rotational power of the output rod 283 to the second processing mechanism 3, realizing multi-structure drive from a single power source, simplifying the device structure and reducing energy consumption. The other side of the transmission belt 282 is wound around the top of the second processing mechanism 3. A drainage hole 284 is provided at the bottom of the output rod 283. The drainage hole 284 is a dedicated channel for the mixed solution to enter the hollow spiral plate 25 from the output rod 283. It can guide the solution in the hollow disk 26 into the hollow spiral plate 25. The bottom of the drainage hole 284 communicates with the inner cavity of the hollow spiral plate 25, ensuring that the solution can flow smoothly into the hollow spiral plate 25, realizing the uniform flow of the solution in the spiral channel, and thus performing comprehensive and efficient cooling treatment on the rising exhaust gas.

[0026] Example 2 further addresses the treatment and transfer of harmful substances in the exhaust gas, building upon Example 1. Please refer to [link / reference needed]. Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10As shown, the dehumidification and filtration mechanism 5 includes a second treatment shell 51, which provides a closed space for the adsorption and purification of waste gas, preventing leakage during the purification process. The second treatment shell 51 is fixedly connected to the right side of the first treatment shell 21. A third transfer pipe 52 is fixedly connected to the left side of the inner cavity of the second treatment shell 51 for transporting the neutralized and cooled waste gas. The inner cavity of the third transfer pipe 52 communicates with the top of the inner cavity of the first treatment shell 21 to prevent waste gas from stagnating at the connection. A second guide block 53 is fixedly connected to the middle of the outer surface of the third transfer pipe 52. The second guide block 53 is arc-shaped and guides the filtered waste gas, ensuring that the waste gas flows smoothly through the first transfer pipe 41 and the second transfer pipe 42 into the second treatment mechanism 3, improving the waste gas transmission efficiency. A filter layer 54 is fixedly connected to the bottom of the second guide block 53. The filter layer 54 is made of highly adsorbent materials, including but not limited to activated carbon and molecular sieves, which can effectively adsorb residual harmful gases in the waste gas. The transfer pipe 52, which contains a small amount of acidic gases, significantly improves the purification effect of the exhaust gas. The bottom of the transfer pipe 52 penetrates the upper part of the filter layer 54 and extends to the bottom of the filter layer 54. This setting allows the exhaust gas to flow upward from the bottom of the inner cavity of the treatment shell 51 and fully pass through all areas of the filter layer 54, ensuring sufficient adsorption and purification. A separation box 55 is fixedly connected to the bottom of the inner cavity of the treatment shell 51. The separation box 55 can collect the condensate in the exhaust gas, realize gas-liquid separation, and prevent water from entering the subsequent treatment structure and affecting the particle capture effect. A baffle 56 is fixedly connected to the inner cavity of the separation box 55. The baffle 56 can change the flow trajectory of the exhaust gas, making the exhaust gas rise in a turbulent manner, increasing the contact time between the exhaust gas and the filter layer 54, improving the adsorption effect, and promoting the condensation and separation of water in the exhaust gas.

[0027] Please see Figure 7 and Figure 8As shown, the cooperating mechanism 4 includes a transfer pipe 41. One end of the transfer pipe 41 is fixedly connected to the right side of the treatment shell 51 to prevent exhaust gas leakage at the connection. The other end of the transfer pipe 41 is fixedly connected to three transfer pipes 42. The three transfer pipes 42 can divert and transmit the exhaust gas, allowing it to enter the various areas of the treatment mechanism 3 evenly, improving the uniformity of subsequent particle capture and preventing insufficient capture due to excessively high exhaust gas concentration in some areas. A conical collecting plate 44 is fixedly connected to the upper end of the three transfer pipes 42. The conical collecting plate 44 has a conical structure, which uses gravity to facilitate the convergence of captured particles to the bottom, reducing... Fewer particles remain in the conical collecting disc 44, facilitating subsequent recycling. Several shaking components 45 are fixedly connected to the upper end of the conical collecting disc 44. The shaking components 45 can generate vibration under the action of cooperation, causing the particles attached to the capture structure to fall off, avoiding blockage of the capture structure and improving particle collection efficiency. A discharge pipe 43 is fixedly connected to the bottom of the conical collecting disc 44. The discharge pipe 43 is a dedicated channel for particle discharge. A solenoid valve is installed inside the discharge pipe 43. The solenoid valve can realize the precise opening and closing of the discharge pipe 43, which makes it convenient for operators to periodically collect particles without continuous supervision, improving the ease of use of the device and reducing labor costs.

[0028] like Figure 10 As shown, the shaking component 45 includes a fixed column 451, with a spring 452 fixedly connected to the top of the fixed column 451. The spring 452 has good elasticity and toughness, and can generate stable swaying vibration when subjected to external force, and drive the rubber ball 453 to shake synchronously. The rubber ball 453 is fixedly connected to the upper end of the spring 452. The rubber ball 453 is soft and can avoid rigid collision when in contact with the mating column 344, reduce component wear, and extend service life. At the same time, it drives the spring 452 to vibrate through contact mating. The rubber ball 453 and the bottom of the processing mechanism 2 3 cooperate with each other. This cooperation can convert the rotational power inside the processing mechanism 2 3 into vibration power, eliminating the need for an additional vibration power source, realizing automatic particle detachment, and improving particle collection effect.

[0029] Example 3 further enhances the capture and collection of particles in the exhaust gas based on Examples 1 and 2. Please refer to [link / reference needed]. Figure 7 , Figure 8 and Figure 9As shown, the second treatment mechanism 3 includes a fixing ring 31, which can stably install the treatment tank 32 in a designated position to ensure that the treatment tank 32 does not shake during operation. The front part of the fixing ring 31 is fixedly connected to the second treatment shell 51. The treatment tank 32 is fixedly connected to the inner cavity of the fixing ring 31. The treatment tank 32 provides a closed space for the final particle capture of the exhaust gas, ensuring that the particles do not diffuse to the outside and avoid secondary pollution. The top of the treatment tank 32 is fixedly connected to an exhaust pipe 33, which is the discharge channel for the purified exhaust gas, and discharges the exhaust gas that meets the emission standards. The top of the treatment tank 32 is rotatably connected to a capture component 34. The capture component 34 can rotate under power drive. The rotational motion creates airflow disturbance, allowing the exhaust gas to fully contact the capture structure, efficiently capturing small particles in the exhaust gas, improving the final effect of exhaust gas purification, and ensuring that the cleanliness of the discharged gas meets the requirements.

[0030] like Figure 8 As shown, the capture assembly 34 includes a transmission rod 341 to ensure the stable rotation of the rotating disk 342. The outer surface of the transmission rod 341 is wound around the transmission belt 282. The rotating disk 342 is fixedly connected to the bottom of the transmission rod 341 to ensure that the capture belt 343 can uniformly contact the exhaust gas. Several capture belts 343 are fixedly connected to the surface of the rotating disk 342. The capture belts 343 are made of highly absorbent material and have a fine capture structure on their surface. They can fully contact the exhaust gas during rotation and efficiently capture small particles in the exhaust gas. The capture efficiency is high and they are not easy to fall off. The bottom of each capture belt 343 is fixedly connected to a mating post 344. The mating post 344 can periodically contact and cooperate with the rubber ball 453 during rotation. The force generated by the contact drives the shaking assembly 45 to vibrate. The mating post 344 cooperates with the rubber ball 453 to realize the automatic fall off of particles, avoid the capture belt 343 from being reduced in capture effect due to particle adhesion, and at the same time ensure that the particles can fall smoothly into the conical collection disk 44 for recycling, realizing the coordinated capture and cleaning.

[0031] The working principle of this solution is as follows: Waste gas generated during the non-woven bag production process first enters the treatment mechanism 2 through conveying pipe 1. One end of conveying pipe 1 is connected to the external non-woven bag production device, and the other end is fixedly connected to the treatment shell 21 of the treatment mechanism 2, providing a stable conveying channel for waste gas treatment. The U-shaped plate 23 at the bottom of the inner cavity of the treatment shell 21 acts as a limiting and blocking barrier for the ethylene glycol and sodium hydroxide mixture solution. When the waste gas enters from the conveying pipe 1, it first reacts with the ethylene glycol and sodium hydroxide mixture solution at the bottom of the treatment shell 21 and undergoes acid-base neutralization. Since the inner cavity of the treatment shell 21 is closed, the neutralized gas will move upwards. Subsequently, the motor 281 starts and drives the output rod 283 to rotate. During the rotation, the connecting rod 24, which is fixedly connected to the bottom, will rotate. As the connecting rod 24 rotates, the neutralized exhaust gas will be compressed, causing it to rise slowly. Simultaneously, the water pump 225 will start, drawing a mixture of ethylene glycol and sodium hydroxide solution from the bottom of the processing shell 21 through the input pipe 221. As the ethylene glycol and sodium hydroxide solution passes between the fixed block 222 and the semiconductor cooling plate 223, the liquid inside will be absorbed by the semiconductor cooling plate 223 and transferred to the heat dissipation fins 224. Subsequently, the ethylene glycol and sodium hydroxide solution enters the water pump 225 and is discharged into the hollow disk 26 through the input pipe 226, which is fixedly connected to the output end. Subsequently, the exhaust gas enters the inner cavity of the hollow spiral plate 25 through the drainage hole 284 on the surface of the output rod 283. This allows the hollow spiral plate 25 to slow the rise of the exhaust gas while the ethylene glycol and sodium hydroxide mixture inside cools the heat in the exhaust gas through a flowing motion. Then, the neutralized and cooled exhaust gas, under the action of the guide block 27, enters the bottom of the inner cavity of the treatment shell 51 through the transfer pipe 3 52. The exhaust gas entering the bottom of the inner cavity of the transfer pipe 3 52 will move upward under the action of the baffle 56, and then pass through the filter layer 54 to adsorb harmful gases in the exhaust gas. After adsorption, the exhaust gas, under the action of the guide block 2 53, enters the inner cavity of the treatment tank 32 through the transfer pipe 41 and the transfer pipe 42. Because the upper part of the transmission rod 341 and... A transmission belt 282 is wound around the upper part of the outer surface of the output rod 283. Therefore, the transmission rod 341 will drive the rotating disk 342 fixedly connected to the bottom to rotate. During the rotation of the rotating disk 342, since several capturing belts 343 are provided on the surface, these capturing belts 343 will capture small particles in the exhaust gas again in a rotating manner. At the same time as the capturing belts 343 rotate, the mating post 344 fixedly connected to the bottom of the capturing belt will cooperate with the rubber ball 453, so that the particles captured by the capturing belts 343 fall onto the surface of the conical collection disk 44. During the cooperation between the rubber ball 453 and the mating post 344, a spring 452 is fixedly connected to the bottom of the rubber ball 453. At this time, the spring 452 will swing and vibrate.This causes particles falling from the surface of the conical collecting disc 44 to concentrate inside the discharge pipe 43. The operator then periodically opens the solenoid valve inside the conical collecting disc 44, allowing the particles to flow into the collection box 6 for recycling. The captured gas is then discharged through the exhaust pipe 33.
