Description

Technical Field

[0001] This utility model relates to the field of high-barrier membrane production equipment technology, specifically to a high-barrier membrane production waste gas treatment device. Background Technology

[0002] High-barrier film is a thin film with high barrier properties against oxygen, water vapor, etc. During the production process of high-barrier film, especially in the stage of heating and melting plastic raw materials, waste gas will be generated, such as small molecules produced by polymer decomposition, as well as gases generated by the volatilization of additives in high-barrier film.

[0003] After the production of high-barrier membranes generates waste gas, in order to prevent the waste gas from polluting the environment and to prevent occupational diseases, waste gas treatment devices will be installed in the workshop to treat the waste gas generated during the production of high-barrier membranes. The waste gas treatment devices usually use adsorption to treat the waste gas, such as activated carbon, molecular sieves, etc.

[0004] In the actual process of treating waste gas using the aforementioned waste gas treatment device, it was found that the temperature of the waste gas produced by the high-barrier membrane production is relatively high, especially the waste gas generated from high-temperature processes such as extrusion. The increased temperature increases the kinetic energy of the gas molecules in the waste gas, making it more difficult for the adsorbate molecules to be captured by the surface of the adsorbent, resulting in a poorer adsorption process, a shorter saturation time of the adsorbent, and a higher frequency of adsorbent replacement.

[0005] In summary, there is a current need for a high-barrier membrane production waste gas treatment device that can efficiently and sustainably treat waste gases. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To address the technical problems in the background section, the following high-barrier membrane production waste gas treatment device is provided:

[0025] Combination Figures 1-4As shown, this utility model provides a high-barrier membrane production waste gas treatment device, including a treatment box 1. The bottom of the treatment box 1 is equipped with an extraction mechanism 2 for gas supply and extraction. Inside the treatment box 1 is a filtration mechanism 3 for treating waste gas. The middle of the inner side of the treatment box 1 is equipped with a filtration assembly 4 for filtering waste gas. Above the filtration assembly 4 is a filtration mechanism 5 for filtering waste gas. The filtration mechanism 3 includes a filtration box 31, a liquid guide box 32, a filter screen 33, a motor 34, a rotating rod 35, and a vortex 36. The filtration box 31 is fixedly installed inside the treatment box 1 and can store liquid that comes into contact with the waste gas. Inside the filtration box 31 is a liquid guide box 32, mirror-mounted inside the filtration box 31. The top edge of the filtration box 31 is equipped with the filter assembly 4. The output end of the motor 34 is equipped with a rotating rod 35, and the bottom of the rotating rod 35 is equipped with a vortex 36. The bottom of the liquid guide box 32 is equipped with a filter... The filter screen 33 and the top of the filter box 31 are provided with an air inlet that communicates with the filter assembly 4. When the waste gas treatment device treats the waste gas, the waste gas is sent into the filter box 31 through the suction mechanism 2. At this time, the liquid in the filter box 31 will adsorb the particulate matter in the waste gas. At the same time, it can reduce the temperature of the waste gas, thereby reducing the temperature of the waste gas to a state suitable for adsorption treatment. During the process of the liquid in the filter box 31 adsorbing heat on the waste gas, the motor 34 drives the rotating rod 35 and the vortex 36 to rotate, so that the liquid in the filter box 31 circulates through the liquid guide box 32. At this time, the filter screen 33 can filter the particulate matter and impurities adsorbed in the waste gas in the liquid, thereby facilitating the maintenance of the liquid's adsorption effect on the waste gas. It should be noted that the particulate matter and impurities accumulated on the filter screen can be cleaned by backwashing or external pipeline.

[0026] In this embodiment, the air filtration mechanism 3 also includes a heat sink 37, a heat sink frame 38, and a mounting plate 39. The heat sink 37 is arrayed on the side of the air filtration box 31. One end of the heat sink 37 is located inside the liquid guide box 32. The heat sink 37 can absorb the heat of the liquid, which is beneficial to maintaining the effect of the liquid absorbing heat and controlling the temperature of the exhaust gas. The other end of the heat sink 37 is located outside the treatment box 1. The heat sink frame 38 is provided on the outside of the air filtration box 31. Multiple mounting plates 39 are provided on the inside of the heat sink frame 38. A fan 391 is provided in the middle of the mounting plate 39. The fan 391 can drive the air to flow outside the heat sink 37, maintaining the heat absorption and heat dissipation effect of the heat sink 37 on the liquid.

[0027] To ensure that the exhaust gas entering the filter box 31 can be uniformly and stably cooled and have particulate matter adsorbed by the liquid, this implementation scheme provides the following design:

[0028] The extraction mechanism 2 includes an extraction box 21, an extraction pump 22, an extraction pipe 23, and an extraction hopper 24. The extraction box 21 is fixedly installed at the bottom of the treatment box 1. The extraction pump 22 is installed inside the extraction box 21. The extraction pump 22 can provide power for the device to treat waste gas. The extraction pipe 23 is provided at the air inlet end of the extraction pump 22. The extraction hopper 24 is provided at the end of the extraction pipe 23 away from the extraction pump 22. The extraction hopper 24 can absorb the waste gas generated by the production of high barrier membrane. The upper air pipe 25 is provided at the air outlet end of the extraction pump 22. The top end of the upper air pipe 25 is located inside the filter box 31.

[0029] As an improvement to the above solution, an upper air frame 26 is provided at the top of the upper air pipe 25. The upper air frame 26 is located at the bottom of the inner side of the air filter box 31. Multiple air nozzles 27 are arrayed on the bottom surface of the upper air frame 26. The air nozzles 27 arrayed below the upper air frame 26 can evenly send the exhaust gas into the bottom of the air filter box 31, so that the exhaust gas can evenly contact the liquid in the air filter box 31, so that the liquid in the air filter box 31 can stably and evenly dissipate heat from the exhaust gas and adsorb particulate matter.

[0030] To enable filter assembly 4 to fully filter the waste gas produced by the high-barrier membrane, this embodiment provides the following design:

[0031] The filter assembly 4 includes a filter box 41, a replacement frame 42, and a second filter screen 43. The filter box 41 is located in the middle of the processing box 1. The replacement frame 42 is located inside the filter box 41. The replacement frame 42 is engaged and slidably connected to the filter box 41. The second filter screen 43 is located in the middle of the replacement frame 42. The second filter screen 43 can perform preliminary treatment on the exhaust gas passing through the gas filtration mechanism 3 and filter out larger particles in the exhaust gas. The second filter screen 43 is exemplarily a non-woven fabric. By engaging and sliding the replacement frame 42 with the filter box 41, the processing device can easily replace the easily clogged second filter screen 43 when processing exhaust gas, which is beneficial to maintaining the treatment effect of the exhaust gas treatment device on the high-barrier membrane.

[0032] In this embodiment, the filtration mechanism 5 includes a filter box 51, which is located on the top of the inner side of the processing box 1. The top of the filter box 51 is provided with an exhaust pipe 52. The filter box 51 is provided with multiple filter layers, such as activated carbon layer, aluminosilicate layer, activated alumina layer, etc.
