A sealing cover 4 is installed on the top of the positioning end 2. The filter bag body 11 is installed inside the support frame 1. The filter bag body 11 includes, from the outside to the inside, a glass fiber layer 13, an activated carbon composite material layer 14, and a polytetrafluoroethylene layer 15.

[0025] In this implementation scheme: By adding a detachable filter box 10 and its bottom filter screen, large particulate dust in the exhaust gas is pre-intercepted, preventing it from directly impacting the filter bag body 11, significantly reducing the physical wear of the main filter bag and extending its service life. The filter bag body 11 is quickly attracted and fixed to the metal sheet 12 by the bottom magnetic block. The filter box 10 adopts a drawer-type pull-out design, and the sealing cover 4 is connected by bolts, all of which can be quickly disassembled and assembled, greatly reducing replacement and cleaning time and improving system availability.

[0026] In an optional embodiment, the bottom of the filter bag body 11 is provided with a magnetic block, and the bottom of the support frame 1 is provided with a corresponding metal sheet 12, and the two are fixed by magnetic attraction.

[0027] In this implementation scheme, the filter bag is quickly installed and removed using a magnetic connection method without the need for tools, which greatly improves the replacement efficiency and ensures that the filter bag remains stable under the action of airflow, preventing displacement.

[0028] In an optional embodiment, the support frame 1 and the positioning end 2 are detachable sleeve structures, which are fixed by at least two positioning bolts 3.

[0029] In this implementation plan: the sleeve structure, together with the positioning bolt 3, provides mechanical stability, ensuring the alignment and fastening of the support frame 1 and the positioning end 2, preventing structural loosening due to vibration or airflow impact, and facilitating overall disassembly and maintenance.

[0030] In an optional embodiment, connecting plates 5 are fixedly connected to both sides of the encapsulation cover 4, and the connecting plates 5 are fixed to the positioning end 2 by fixing bolts 6.

[0031] In this implementation scheme, the combination of connecting plate 5 and fixing bolt 6 achieves uniform pressing of the encapsulation cover 4, enhances sealing performance, prevents exhaust gas leakage, and at the same time makes the opening and closing of the encapsulation cover 4 easy, facilitating the maintenance and replacement of the internal filter box 10.

[0032] In an optional embodiment, a connecting tube 7 is fixedly provided at the center of the upper part of the encapsulation cover 4, and a sealing ring 8 is bonded to the outside of the connecting tube 7.

[0033] In this implementation plan, the design of the connecting pipe 7 and the sealing ring 8 ensures the sealing of the connection with the external pipeline, avoids exhaust gas leakage, improves system safety, and adapts to interfaces with different pipe diameters, thereby enhancing equipment compatibility.

[0034] In an optional embodiment, the bottom of the filter cartridge 10 is provided with a filter screen for intercepting large dust particles.

[0035] In this implementation scheme: the filter screen pre-treats large particulate impurities in the exhaust gas, reduces the amount of dust that directly impacts the filter bag body 11, reduces the wear of the main filter bag, extends its service life, and improves the overall filtration efficiency.

[0036] In an optional embodiment, the filter cartridge 10 is an embedded structure that can be lifted upwards from the mounting slot 9 for removal.

[0037] In this implementation plan: the embedded upward lifting design saves horizontal space, making it suitable for scenarios with limited installation space. It is also simple and quick to operate, allowing for individual cleaning or replacement of the filter box 10 without disassembling other parts, thus improving maintenance efficiency.

[0038] Working principle:

[0039] Filter bag fixing and sealing: The filter bag body 11 is installed into the support frame 1, and the bag opening is folded over and fitted onto the support frame 1. The bottom of the filter bag body 11 is provided with a magnetic block, which attracts the metal piece 12 at the bottom of the support frame 1 to achieve quick installation and accurate positioning, and prevent the filter bag from shaking or shifting under the action of airflow. The entire filter bag is fixed to the positioning end 2 through the support frame 1 and reinforced by the positioning bolts 3, making the structure stable.

[0040] Encapsulation: The encapsulation cover 4 is fixed to the positioning end 2 by the connecting plate 5 and the fixing bolt 6, which facilitates quick opening and closing;

[0041] Exhaust gas entry and pretreatment: Connect the external pipe to the connecting pipe 7. The connecting pipe 7 is equipped with a sealing ring 8 on the outside to ensure a tight and leak-free connection with the external pipe. High-temperature exhaust gas enters the system through the connecting pipe 7 and first enters the filter box 10. This box is located in the mounting groove 9 of the positioning end 2. The bottom is equipped with a filter screen, which can intercept large particles of dust and impurities, reduce the burden on the main filter bag, and extend its service life.

[0042] Multi-layer filter bag filtration: Pre-treated waste gas flows downwards and enters the filter bag body 11. The filter bag adopts a three-layer composite structure. The glass fiber layer 13 is located on the outermost layer, which has excellent high temperature resistance and mechanical strength, and can effectively block larger particles and withstand the impact of high-temperature waste gas. The activated carbon composite material layer 14 is located in the middle layer, which adsorbs substances such as SO2 and NO in the waste gas. x It removes harmful gases such as HF, and plays a role in deacidification and denitrification. The polytetrafluoroethylene layer 15 is located in the innermost layer and has excellent chemical inertness and corrosion resistance, preventing acidic gases from corroding the filter bag and ensuring long-term stable operation.

[0043] Maintenance: The filter box 10 can be disassembled for cleaning or replacement, and the filter bag body 11 can also be quickly removed by releasing the magnetic and bolt connections, which greatly reduces the difficulty and time cost of maintenance.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
