[0002] Waste gas treatment refers to the pretreatment and purification of waste gas generated in industrial and other places to reduce harm to the environment and human health.

[0003] The waste gas generated when using fossil fuels such as coal, oil and natural gas, as well as the waste gas emitted during the production process of chemical plants, steel mills, pharmaceutical plants, etc., are all toxic and harmful gases and cannot be discharged directly into the air. They must undergo waste gas treatment and can only be discharged directly if they meet the standards.

[0004] The waste gas that needs to be treated before discharge is likely to contain particulate impurities. If the impurities are large in size and flow into the subsequent waste gas treatment process, it is easy to reduce the quality of the treated waste gas, making it more difficult to meet the emission standards. Therefore, an exhaust gas conveying pipeline is proposed, which can remove large particulate impurities in the exhaust gas in advance. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 A waste gas conveying pipeline includes an exhaust pipe 1, the exhaust end of the exhaust pipe 1 is connected to an air intake pipe 2. The specific connection method can refer to the existing flange connection. The exhaust gas discharged from the exhaust pipe 1 is received by the air intake pipe 2. A filter tube 3 is installed on the lower side of the air intake pipe 2. The lower side of the filter tube 3 is connected to the exhaust pipe 4. The exhaust gas in the air intake pipe 2 passes through the filter tube 3 and enters the exhaust pipe 4. The exhaust pipe 4 can be connected to another pipeline to transport the preliminarily treated exhaust gas to the next link.

[0030] See also Figure 1 , Figure 3 and Figure 4 In this embodiment, a filter plate 5 is installed inside the filter tube 3, and large particle impurities carried in the exhaust gas are filtered through the filter plate 5 to perform preliminary treatment on the exhaust gas. The filter tube 3 is configured as a two-stage structure, consisting of an upper pipe 31 and a lower pipe 32. The upper pipe 31 is located at the upper part of the filter tube 3, and the lower pipe 32 is located at the lower part of the filter tube 3. The filter plate 5 is located at the joint of the upper pipe 31 and the lower pipe 32.

[0031] Specifically, the filter plate 5 is composed of a mounting ring 51, a filter screen 52 and a docking ring 53. The filter screen 52 is fixed inside the mounting ring 51, and large particles of impurities in the exhaust gas are filtered through the filter screen 52. The outer end of the mounting ring 51 is fixed with a docking ring 53. The mounting ring 51 can be clamped with the upper pipe 31 and the lower pipe 32 through the docking ring 53, so that the filter plate 5 is installed inside the filter tube 3, wherein the upper and lower surfaces of the docking ring 53 are bonded with sealing gaskets, and the docking ring 53 is fitted with the upper pipe 31 and the lower pipe 32 through the sealing gasket, thereby improving the sealing effect of the connection between the filter plate 5 and the filter tube 3 to prevent exhaust gas leakage.

[0032] Furthermore, a discharge pipe 311 is fixedly connected to the outer end of the upper pipe 31, and a valve is installed inside the discharge pipe 311. At the same time, the filter plate 5 is inclined inside the filter pipe 3, and the lower part of the filter plate 5 is connected to the inlet end of the discharge pipe 311, so that the particulate impurities filtered by the filter screen 52 can automatically slide into the discharge pipe 311 due to gravity, and the particulate impurities are discharged through the discharge pipe 311.

[0033] For further examples, see Figure 3 and Figure 4 A positioning ring 6 is slidably connected to the inner side of the lower end of the air inlet cylinder 2, and a second slot 62 is provided on the lower side of the positioning ring 6. At the same time, a first slot 41 is provided on the upper side of the exhaust cylinder 4, so that the positioning ring 6 is clamped with the upper end of the filter tube 3 through the second slot 62, and the exhaust cylinder 4 is clamped with the lower end of the filter tube 3 through the first slot 41, thereby fixing the filter tube 3.

[0034] Slide blocks 61 are fixedly connected to both ends of the positioning ring 6, so that the positioning ring 6 can slide in a limited manner in the air intake cylinder 2 through the slide blocks 61, and an adjustment component is installed inside the air intake cylinder 2 to adjust the sliding of the positioning ring 6, so as to facilitate the removal of the filter tube 3. The adjustment component includes a micro motor 7 and a drive rod 71. The micro motor 7 is installed at the outer end of the air intake cylinder 2, and the drive rod 71 is connected to the output shaft of the micro motor 7. The specific connection method can adopt the existing technology, and the outer end of the drive rod 71 is fixedly connected with an active bevel gear. Starting the micro motor 7 can drive the drive rod 71 to rotate, and the micro motor 7 can be turned to rotate. When the driving rod 71 rotates, the driven rod 72 is driven by the thread on the inside of the slider 61 near one end of the adjusting component. The driven rod 72 is rotatably connected to the inside of the air intake cylinder 2, and a driven bevel gear is fixed to the upper end of the driven rod 72, wherein the driving rod 71 is meshed with the driven bevel gear of the driven rod 72 through the active bevel gear, and can drive the driven rod 72 to rotate when the driving rod 71 rotates. Since the driven rod 72 is threadedly connected to the slider 61 at one end, the positioning ring 6 can be raised and lowered. When the positioning ring 6 rises and is no longer clamped with the upper pipe 31, the filter tube 3 can be taken out from the exhaust cylinder 4 and disassembled.

[0035] Furthermore, a seal 21 is sleeved on the outer side of the positioning ring 6, the seal 21 is fixed to the outer end of the intake pipe 2, and sealing gaskets are bonded to the upper end of the upper pipe 31 and the lower end of the lower pipe 32. Through the above arrangement, the sealing effect of the intake pipe 2 when transporting exhaust gas to the exhaust pipe 4 through the filter tube 3 is maintained.

[0036] See also Figure 2 and Figure 3 In another embodiment, a deflector 8 is installed inside the exhaust pipe 4 to speed up the exhaust gas delivery rate. The deflector 8 is composed of a support block 81 and a fan 82. The support block 81 is located inside the exhaust pipe 4 and is fixed to the inner wall of the exhaust pipe 4 through a bracket. The fan 82 is rotatably connected to the upper side of the support block 81. A driving motor is installed at the bottom of the support block 81 to drive the fan 82 to rotate. The exhaust gas is sucked in by the rotation of the fan 82 to speed up the delivery of the exhaust gas.

[0037] Working principle: The exhaust pipe 1 is installed with the air intake cylinder 2 by means of flange connection. After the exhaust pipe 1 transports the exhaust gas to the air intake cylinder 2, the exhaust gas enters the filter pipe 3. When the exhaust gas passes through the filter plate 5, the filter screen 52 filters the large particles of impurities. After filtration, the impurities slide into the discharge pipe 311. After the exhaust gas is transported, the valve inside the discharge pipe 311 is opened to discharge the impurities.

[0038] When the filter plate 5 needs to be replaced or cleaned and maintained, the micro motor 7 is first started to drive the driving rod 71 to rotate, and then the driven rod 72 is rotated. At this time, the positioning ring 6 rises. When the positioning ring 6 is no longer engaged with the upper pipe 31, the filter tube 3 can be removed from the exhaust pipe 4 as a whole, and the filter tube 3 can be split into two sections - the upper pipe 31 and the lower pipe 32, so that the filter plate 5 can be taken out from the filter tube 3 as a whole, and the filter plate 5 can be cleaned or replaced according to the situation.
