Description

Technical Field

[0001] This utility model belongs to the field of hollow fiber membrane production tail gas treatment technology, and in particular relates to a high-efficiency tail gas treatment device for hollow fiber membrane production. Background Technology

[0002] Hollow fiber membrane production is a complex process involving multiple technologies and materials. It uses raw materials such as polysulfone and dimethylacetamide to prepare membranes with selective permeation characteristics through methods such as non-solvent-induced phase separation and thermally induced phase separation. By preparing a high-temperature homogeneous solution with polymers and high-boiling-point diluents, phase separation occurs after cooling, ultimately obtaining a membrane material with a microporous structure.

[0003] However, the production of hollow fiber membranes generates a large amount of exhaust gas. If this gas is not treated and is directly discharged into the atmosphere, it will have a negative impact on the environment and air quality, thereby affecting human health and the ecosystem, and may also pose a threat to the health of residents around the factory. Therefore, we propose a highly efficient exhaust gas treatment device for hollow fiber membrane production. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient exhaust gas treatment device for hollow fiber membrane production. The device discharges exhaust gas from the inlet pipe into a fixed cylinder, where a filter plate isolates some particulate impurities, completing the first filtration. Then, through spraying from several nozzles, other dust particles and other particles in the exhaust gas are mixed with water and flow down, completing the second filtration. The gas then enters the filter box through a gas delivery pipe, where activated carbon filter rods adsorb harmful substances. This solves the problem that existing hollow fiber membrane production processes generate large amounts of exhaust gas, which, if discharged directly into the atmosphere without treatment, negatively impacts the environment and air quality, thereby affecting human health and the ecosystem.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0025] Please see Figure 1-5As shown, this utility model is a high-efficiency exhaust gas treatment device for hollow fiber membrane production, including a fixed cylinder 1. A rotating door 11 is rotatably connected to the front of the fixed cylinder 1 via a hinge. A fixing ring 12 is fixedly connected to the outer surface of the fixed cylinder 1, and a support frame 121 is fixedly connected to the bottom of the fixing ring 12. A fixing hole is opened on the back of the fixed cylinder 1, and an air inlet pipe 2 is fixedly connected to the inner wall of the fixing hole. A filter plate 23 is fixedly connected to the inner wall of the fixed cylinder 1, and a nozzle 321 is arranged above the filter plate 23. An air supply pipe 4 is fixedly connected to the side of the inner wall of the fixed cylinder 1 away from the filter plate 23. A filter box 41 is fixedly connected to the top of the air supply pipe 4, and an activated carbon filter rod 51 is arranged on the inner wall of the filter box 41. This utility model, by setting the air inlet pipe 2, specifically discharges the exhaust gas from the air inlet pipe 2. The gas is introduced into the fixed cylinder 1, where the filter plate 23 isolates some of the particulate impurities in the exhaust gas, completing the first filtration. Then, through the spraying of several nozzles 321, other dust and other particles in the exhaust gas are mixed with water and flow down, completing the second filtration. The gas then enters the filter box 41 through the gas supply pipe 4, where the activated carbon filter rod 51 adsorbs harmful substances. This allows the device to efficiently filter the exhaust gas generated during production, preventing it from being directly discharged into the atmosphere and causing environmental pollution. A valve 21 is fixedly connected to the bottom of the fixed cylinder 1, and a water outlet pipe 211 is fixedly connected to the right side of the valve 21. A connection hole is opened on the back of the fixed cylinder 1, and a water supply pipe 22 is fixedly connected to the inner wall of the connection hole. A connecting pipe is fixedly connected to the bottom of the water supply pipe 22. 3. A rotating block 31 is rotatably connected to the bottom of connecting pipe 3 via a pin. A water outlet pipe 32 is fixedly connected to the front of the rotating block 31. The water outlet pipe 32 allows water inside the fixed cylinder 1 to be discharged through the valve 21. The bottom of the water outlet pipe 32 is fixedly connected to the top of the nozzle 321. There are several nozzles 321 arranged in a horizontal array. There are two water outlet pipes 32, symmetrically arranged with connecting pipe 3 as the center. The arrangement of several nozzles 321 allows for a comprehensive spraying of exhaust gas, preventing incomplete filtration. A limiting ring 411 is fixedly connected to the outer surface of the filter box 41. The top of the filter box 41 contacts the connecting pipe 42. The bottom of the second connecting pipe 42 is fixedly connected to a slide rail 412. The inner wall of the slide rail 412 contacts the outer surface of the limiting ring 411. The top of the fixed cylinder 1 has a slot, and the inner wall of the slot is fixedly connected to an air outlet pipe 43. The bottom of the air outlet pipe 43 is fixedly connected to the top of the second connecting pipe 42. The bottom of the second connecting pipe 42 contacts the top of the filter box 41. The slide rail 412 allows the limiting ring 411 to move within its inner wall, making its movement smoother and more restrictive. The inner wall of the filter box 41 is fixedly connected to a cover plate 5. The outer surface of the filter box 41 away from the limiting ring 411 is fixedly connected to a limiting ring 521. The top of the air supply pipe 4 is fixedly connected to a slide rail 52. This utility model uses the slide rail 52 to open the rotating door 11.Workers can pull the filter box 41 out from the slide rail 52 and slide rail 412 by pulling the handle 53. After pulling it out, the activated carbon filter rods 51 inside can be replaced by opening the cover plate 5. After replacement, the limiting ring 521 is aligned with the slide rail 52 and pushed in to complete the reset, improving the overall convenience of the device and making it easier for workers to replace the activated carbon filter rods 51, thus improving work efficiency. The outer surface of the slide rail 52 is in contact with the limiting ring 521. The filter box 41 is fixedly connected to the front with the handle 53. There are several activated carbon filter rods 51 arranged in a ring array. The slide rail 52 allows the limiting ring 521 to move within it, preventing it from shifting.

[0026] A specific application of this embodiment is as follows: The exhaust gas generated during hollow fiber membrane production is discharged into the fixed cylinder 1 through the inlet pipe 2. The gas then moves upwards, and the filter plate 23 isolates some of the particulate impurities in the exhaust gas, thus completing the first filtration. Subsequently, water is injected into the water supply pipe 22 to increase the water pressure. Since the other end of the water supply pipe 22 is sealed, the water enters the connecting pipe 3 and is sprayed out from several nozzles 321 through the rotating block 31 and the outlet pipe 32. Because the rotating block 31 is connected by a pin, the nozzles at both ends... When spraying simultaneously, the rotating block 31 will rotate, allowing the nozzle 321 to rotate and spray. This mixes other dust particles in the exhaust gas with water, which then flows through the filter plate 23 to the bottom of the fixed cylinder 1, completing the second filtration of the exhaust gas. The gas then enters the filter box 41 through the gas supply pipe 4. The filter box 41 contains several activated carbon filter rods 51, which adsorb harmful substances in the exhaust gas. Since the top of the cover plate 5 has several air outlets, after three filtrations... The exhaust gas is discharged from the outlet pipe 43 through the connecting pipe 2 42. Activated carbon filter rods are widely used in various air purification and water treatment systems. Their porous structure gives them a strong adsorption capacity, which can effectively remove harmful substances in the exhaust gas such as chlorine smell, odor, suspended solids and reduce lead. This filter element can provide efficient pollutant removal in a variety of applications, including recovering carbon dioxide from industrial emissions or removing harmful gases. This device can efficiently filter the exhaust gas generated in production, preventing it from being directly discharged into the atmosphere and causing environmental pollution. After the device has been used for a long time, the activated carbon filter rod 51 needs to be replaced. The rotating door 11 can be opened, and the operator can pull the handle 53 to pull the filter box 41 out from the slide 2 52 and slide 1 412. After pulling it out, the cover plate 5 can be opened to replace the several activated carbon filter rods 51 inside. After replacement, the limiting ring 2 521 is aligned with slide 2 52 and pushed in to complete the reset, improving the overall convenience of the device and making it easier for operators to replace the activated carbon filter rods 51, thus improving the work efficiency of the operators.
