Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a corrosion-resistant pipeline for waste gas treatment. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. A pipeline is a special pipeline system used to transport substances (such as liquids, gases, solid particles, dust, etc.) from one place to another. Therefore, pipelines play a key role in waste gas treatment systems. They are mainly used to transport the generated waste gas from the source to the waste gas treatment equipment for subsequent purification and treatment.

[0003] Existing exhaust gases often contain various harmful substances, such as particulate matter, soot, and toxic gases. Without a filtration system for pretreatment, these harmful substances will be directly discharged into the environment through pipelines, leading to a decline in air quality and threatening the ecological environment and human health.

[0004] For example, the exhaust gas conveying pipeline disclosed in patent CN208268555U does not have a filtration mechanism. Without a filtration mechanism, it is impossible to effectively prevent pollutants such as particulate matter, dust, and oil mist from entering or exiting the pipeline, which will pollute the treatment equipment or the environment. Furthermore, particulate matter and dust impurities in the exhaust gas may accumulate inside the conveying pipeline during the conveying process, causing blockage and affecting the conveying efficiency. At the same time, these impurities may also cause wear and tear on the conveying pipeline and connecting parts, shortening their service life.

[0005] Therefore, it is necessary to invent a corrosion-resistant conveying pipeline for waste gas treatment to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a corrosion-resistant conveying pipeline for waste gas treatment, in order to solve the problem of the lack of filtration function in the technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant conveying pipeline for waste gas treatment, comprising a pipeline body, an air inlet, an air outlet, and a filter pipe. An air inlet is provided at one end of the pipeline body, and an air outlet is provided at the other end. Flanges are installed at the air inlet and outlet, and a filter pipe is installed on the flanges. A plug is fixedly installed on the side wall of the filter pipe. A slot is provided at the contact point between the flange and the plug. A bearing seat is fixedly installed on one side wall of the flange. A mounting plate is hinged to the bearing seat, and a fixing bolt is connected through the mounting plate. A screw hole is provided at the contact point between the fixing bolt and the side wall of the filter pipe. A dust collection hopper is provided at the bottom of the filter pipe. A first anti-corrosion layer is provided on the outer wall of the pipeline body, and a second anti-corrosion layer is provided on the inner wall of the pipeline body.

[0008] Preferably, there are two filter tubes, one of which is located at the air inlet and the other at the air outlet. This effectively filters the incoming and outgoing exhaust gas, improving the efficiency and quality of exhaust gas treatment. Through dual filtration, it can ensure that harmful substances in the exhaust gas are removed to the greatest extent.

[0009] Preferably, a sealing ring is provided on the side wall of the filter tube, and the sealing ring is located at the connection between the filter tube and the flange to ensure the sealing of the connection between the filter tube and the flange and prevent exhaust gas leakage.

[0010] Preferably, the insert and the slot are connected by a snap-fit ​​connection, and the size of the insert matches the size of the slot. The snap-fit ​​connection between the insert and the slot allows for easy installation and removal of the filter tube, improving the convenience of maintenance.

[0011] Preferably, the fixing bolt and the screw hole are connected by threads, and the outer thread of the fixing bolt and the inner thread of the screw hole are matched. Through the threaded connection between the fixing bolt and the screw hole, the filter tube can be further fixed to prevent it from shifting or loosening during operation.

[0012] Preferably, the filter tube is provided with a coarse filter layer, a medium filter layer and a high-efficiency filter layer inside. The medium filter layer is disposed between the coarse filter layer and the high-efficiency filter layer. The outer walls of the coarse filter layer, the medium filter layer and the high-efficiency filter layer are tightly fitted to the inner wall of the filter tube. The coarse filter layer, the medium filter layer and the high-efficiency filter layer can remove particles of different sizes in the exhaust gas in sequence, and can improve the filtration effect step by step.

[0013] Preferably, a dust collection hopper is provided directly below the coarse filter layer, the medium filter layer and the high efficiency filter layer, which can conveniently collect the dust generated during the filtration process.

[0014] Preferably, the first and second anti-corrosion layers are anti-corrosion coatings. The first and second anti-corrosion layers are uniformly coated on the outer and inner surfaces of the pipeline body by spraying. The first and second anti-corrosion layers can enhance the corrosion resistance of the pipeline and extend its service life.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By installing filter pipes, filter pipes are installed at both the inlet and outlet of the conveying pipeline. The filter pipes can effectively filter particles of different sizes in the exhaust gas. After the exhaust gas passes through the three layers of coarse, medium and high efficiency filter layers inside the filter pipes, it can ensure that the exhaust gas meets certain quality standards and reduce the wear and corrosion of the conveying pipeline and connecting equipment caused by impurities in the exhaust gas.

[0017] 2. With the setting of plugs and slots, the filter tube is inserted into the air inlet and outlet of the conveying pipeline through the plugs, and is fixed by fixing bolts and screw holes. This allows the filter tube to be installed quickly and easily at the air inlet and outlet of the conveying pipeline without complicated installation steps or tools, which facilitates the later maintenance and upkeep of the filter tube.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The diagram shows a corrosion-resistant conveying pipeline for waste gas treatment, comprising a pipeline body 1, an air inlet 2 at one end of the pipeline body 1, and an air outlet 3 at the other end of the pipeline body 1. A flange 4 is installed at both the air inlet 2 and the air outlet 3. A filter pipe 5 is installed on the flange 4, and a plug 7 is fixedly installed on the side wall of the filter pipe 5. A slot 8 is provided at the contact point between the flange 4 and the plug 7. A bearing seat 9 is fixedly installed on one side wall of the flange 4, and a mounting plate 1 is hinged to the bearing seat 9. 0. A fixing bolt 11 is connected through the mounting plate 10. A screw hole 12 is opened at the contact position between the fixing bolt 11 and the side wall of the filter pipe 5. A dust collection hopper 16 is set at the bottom of the filter pipe 5. The outer wall of the pipe body 1 is provided with a first anti-corrosion layer 17, and the inner wall of the pipe body 1 is provided with a second anti-corrosion layer 18. The first anti-corrosion layer 17 and the second anti-corrosion layer 18 are anti-corrosion coatings. The first anti-corrosion layer 17 and the second anti-corrosion layer 18 are evenly coated on the outer and inner wall surfaces of the pipe body 1 by spraying.

[0027] Two filter tubes 5 are provided, one at the air inlet 2 and the other at the air outlet 3. A sealing ring 6 is provided on the side wall of the filter tube 5, and the sealing ring 6 is located at the connection between the filter tube 5 and the flange 4. The insert 7 and the slot 8 are connected by a snap-fit ​​connection, and the size of the insert 7 matches the size of the slot 8. The fixing bolt 11 and the screw hole 12 are connected by a thread, and the outer thread of the fixing bolt 11 matches the inner thread of the screw hole 12. The filter tube 5 is provided with a coarse filter layer 13, a medium filter layer 14 and a high-efficiency filter layer 15. The medium filter layer 14 is located between the coarse filter layer 13 and the high-efficiency filter layer 15. The outer walls of the coarse filter layer 13, the medium filter layer 14 and the high-efficiency filter layer 15 are tightly fitted to the inner wall of the filter tube 5. A dust collection hopper 16 is provided directly below the coarse filter layer 13, the medium filter layer 14 and the high-efficiency filter layer 15.

[0028] By installing a filter pipe 5 at both the air inlet 2 and the air outlet 3, dual filtration of the exhaust gas is achieved. This ensures that the exhaust gas is fully treated when entering and leaving the pipe body 1, improving the efficiency and quality of exhaust gas treatment. The snap-fit ​​connection between the insert 7 and the slot 8, as well as the threaded connection between the fixing bolt 11 and the screw hole 12, together ensure the stable installation of the filter pipe 5. This design not only facilitates the installation and disassembly of the filter pipe 5, but also ensures its stability during operation, preventing loosening or falling off due to vibration or impact. Furthermore, the sealing ring 6 at the connection between the filter pipe 5 and the flange 4 ensures a tight connection, preventing exhaust gas leakage and guaranteeing the filtration effect and the safety of the working environment. At the same time, the coarse filter layer 13, the medium filter layer 14, and the high-efficiency filter layer 15 achieve multi-stage filtration of the exhaust gas, ensuring efficient treatment and safe emission of the exhaust gas.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual appendix Figure 1-5 When using this utility model, first install the two filter tubes 5 on the flanges 4 of the air inlet 2 and the air outlet 3 respectively, align the insert 7 with the slot 8 and snap it in, and ensure that the sealing ring 6 is intact and correctly installed at the connection between the filter tube 5 and the flange 4 to prevent exhaust gas leakage. Then use the mounting plate 10 and fixing bolts 11 with screw holes 12 to further fix the filter tube 5 to ensure that the filter tube 5 is firmly connected. Then the conveying pipeline can be installed in a suitable position to carry out the exhaust gas conveying work.

[0031] When exhaust gas enters the pipe body 1 through the inlet 2, it first passes through the coarse filter layer 13 in the filter pipe 5 at the inlet 2 to remove large particles. Next, it passes through the medium-efficiency filter layer 14 to further remove medium-sized particles. Finally, it passes through the high-efficiency filter layer 15 to remove fine particles and harmful gases. During the filtration process, the dust captured by each filter layer falls into the dust collection hopper 16 below for easy cleaning. The exhaust gas, having undergone three layers of filtration, enters the pipe body 1 and exits through the outlet 3. As the exhaust gas exits from the outlet 3, the filtered waste... The air is filtered again through the filter pipe 5 at the air outlet 3. The filtered impurities fall into the dust collection hopper 16, which can easily collect the dust particles generated during the filtration process, thus ensuring that the exhaust gas has been significantly purified and achieving efficient exhaust gas treatment. When the filter pipe 5 needs to be disassembled and replaced after long-term use, simply loosen the fixing bolt 11 to remove the filter pipe 5. The operation is simple and convenient. At the same time, the first anti-corrosion layer 17 and the second anti-corrosion layer 18 can protect the pipe body 1 from corrosion, effectively preventing the pipe body 1 from being corroded and extending its service life.
