Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, and in particular to a waste gas purification device. Background Technology

[0002] With the rapid development of industry, the amount of waste gas emissions generated during various industrial production processes is increasing daily. Among many industrial sectors, those involving the production and application of water-based resins are particularly prominent. Water-based resins, as an environmentally friendly material, are widely used in coatings, adhesives, inks, and many other fields. However, during their production, processing, and use, waste gas containing volatile organic compounds (nitrogen oxides, sulfur dioxide), odorous substances, and some particulate matter is still generated. Most existing waste gas purification equipment has a fixed structure, making it difficult to disassemble and replace purification components. During the purification process of water-based resin waste gas, due to the complex composition of the waste gas, a large amount of pollutants accumulates inside the purification components (such as the purification tank) after prolonged operation, leading to a decrease in purification efficiency. Traditional equipment cannot easily clean and maintain the purification components, which not only affects the continuity of production but also increases equipment maintenance costs and time. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a waste gas purification device to solve the problem that after long-term operation of existing purification equipment, a large amount of pollutants will accumulate inside the purification components (such as the purification tank), resulting in a decrease in purification efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An exhaust gas purification device includes a fixed frame, an exhaust gas transmission pipe, and a purification component. The exhaust gas transmission pipe is horizontally installed on the inner side of the fixed frame and is located above the purification component. The purification assembly includes multiple independent purification tanks. Each purification tank has a detachable fixing ring installed on its exterior. A series block is installed between the fixing rings, and a drive block is connected to the fixing ring located on the outermost side. The inner wall of the fixed frame has a movable groove for sliding installation of the drive block.

[0005] Preferably, the purification tank includes an upper tank and a lower tank, and the fixing ring is disposed at the joint between the upper tank and the lower tank.

[0006] Preferably, fixing bolts are distributed around the outer wall of the fixing ring.

[0007] Preferably, the outer surfaces of the upper tank and the lower tank are respectively provided with threaded holes adapted to fixing bolts, and a discharge pipe is installed at the bottom of the lower tank.

[0008] Preferably, the upper surface and the bottom surface of the drive block are both provided with protruding sliders.

[0009] Preferably, the fixed frame has a movable groove, and the slider slides inside the movable groove.

[0010] Preferably, a drive motor is mounted on the outer wall of the fixing frame, and a drive screw is connected to the output shaft of the drive motor.

[0011] Preferably, the drive screw is rotatably embedded in the moving groove, and the drive block has a threaded hole adapted to the drive screw.

[0012] Preferably, an air inlet pipe is connected to the upper surface of the upper tank. The air inlet pipe is a flexible hose, and the other end of the air inlet pipe is connected to an exhaust gas transmission pipe.

[0013] Preferably, a retractable spray pipe is connected to the back of the upper tank, and the end of the spray pipe away from the upper tank is connected to the purified water tank.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, the purification tank can be easily moved and slid out after prolonged use. The purification tank features a detachable upper and lower tank structure, connected and secured by fixing rings and bolts, facilitating thorough cleaning and maintenance of the tank's interior by operators. Multiple independent purification tanks are connected in series via connecting blocks and fixing rings, allowing for flexible adjustment of the number of tanks involved in purification based on actual exhaust gas emissions. When exhaust gas emissions are low, only some tanks can be activated, reducing energy consumption; conversely, when emissions are high, all tanks can be activated to ensure timely and effective treatment of the exhaust gas. The detachable tank design enables operators to perform deep cleaning of both the upper and lower tanks, removing accumulated contaminants and ensuring the cleanliness of the tank's interior.

[0024] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides an exhaust gas purification device, including a fixing frame 1, an exhaust gas transmission pipe 2, and a purification component 3. The exhaust gas transmission pipe 2 is horizontally installed on the inner side of the fixing frame 1, and the exhaust gas transmission pipe 2 is located above the purification component 3. The purification component 3 includes multiple independent purification tanks 10. Fixing rings 8 are detachably installed on the outside of the purification tanks 10. Series blocks 7 are installed between the fixing rings 8. A driving block 4 is connected to the outermost fixing ring 8. The inner wall of the fixing frame 1 has a moving groove 14 adapted to the sliding installation of the driving block 4. An air inlet pipe 9 is connected to the upper surface of the upper tank 11. The air inlet pipe 9 is a flexible hose structure, and the other end of the air inlet pipe 9 is connected to the exhaust gas transmission pipe 2.

[0025] like Figure 3 As shown, the purification tank 10 includes an upper tank 11 and a lower tank 12. A fixing ring 8 is disposed at the joint between the upper tank 11 and the lower tank 12, and a sealing ring is provided at the joint. Fixing bolts are installed around the outer wall of the fixing ring 8. The outer surfaces of the upper tank 11 and the lower tank 12 are respectively provided with threaded holes adapted to the fixing bolts. A discharge pipe 6 is installed at the bottom of the lower tank 12. The upper surface and the bottom end face of the drive block 4 are both provided with protruding sliders 13. A retractable spray pipe 5 is connected to the back of the upper tank 11, and the end of the spray pipe 5 away from the upper tank 11 is connected to the purified water tank.

[0026] like Figure 4As shown, the fixed frame 1 has a movable groove 14, and the slider 13 slides inside the movable groove 14. A drive motor 15 is installed on the outer wall of the fixed frame 1, and a drive screw 16 is connected to the output shaft of the drive motor 15. The drive screw 16 is rotatably embedded in the movable groove 14, and the drive block 4 has a threaded hole adapted to the drive screw 16.

[0027] The working principle of the technical solution provided by this utility model is as follows: This waste gas purification equipment mainly consists of a fixed frame 1, a waste gas transmission pipe 2, and a purification component 3. Its working principle revolves around the flexible operation and efficient purification of the purification tank 10 in the purification component 3. Water-based resin waste gas generated in industrial production is first transported through the waste gas transmission pipe 2. The waste gas transmission pipe 2 is horizontally installed inside the fixed frame 1 and located above the purification component 3, providing a stable transmission channel for the waste gas and ensuring that the waste gas can accurately and smoothly enter the subsequent purification tank 10. Each purification tank 10 consists of an upper tank 11 and a lower tank 12. An air inlet pipe 9, a flexible hose, is connected to the upper surface of the upper tank 11, with the other end connected to the exhaust gas transmission pipe 2. Exhaust gas enters the upper tank 11 through the exhaust gas transmission pipe 2 and the air inlet pipe 9. Simultaneously, a retractable spray pipe 5 is connected to the back of the upper tank 11, with the end of the spray pipe 5 furthest from the upper tank 11 connected to a purification water tank. After the exhaust gas enters the upper tank 11, the purification liquid (sodium carbonate and sodium hydroxide) in the purification water tank is sprayed out through the spray pipe 5, fully contacting the nitrogen oxides and sulfur dioxide in the exhaust gas. This absorbs and reacts with volatile organic compounds, odor substances, and some particulate matter in the exhaust gas, achieving purification. The pre-purified exhaust gas then enters the lower tank 12 for further purification. The lower tank 12 has an internal filter (graphene) that filters the exhaust gas again. Finally, the purified gas that meets emission standards is discharged from the exhaust pipe 6 at the bottom of the lower tank 12.

[0028] The purification assembly 3 comprises multiple independent purification tanks 10, each with a detachable fixing ring 8. These fixing rings 8 are interconnected via series blocks 7, forming a series structure. A drive block 4 is connected to the outermost fixing ring 8. The drive block 4 has a slider 13 protruding from both its upper and lower surfaces, sliding within a suitable moving groove 14 on the inner wall of the mounting frame 1. A drive motor 15 is mounted on the outer wall of the mounting frame 1. The output shaft of the drive motor 15 is connected to a drive screw 16, which rotates within the moving groove 14. The drive block 4 has a threaded hole adapted to the drive screw 16. When the drive motor 15 starts, it drives the drive screw 16 to rotate. The interaction between the drive screw 16 and the threaded hole on the drive block 4 causes the drive block 4 to move along the moving groove 14, thereby moving the entire series of purification tanks 10 out of the mounting frame 1.

[0029] Because the fixing ring 8 is located at the joint between the upper tank 11 and the lower tank 12, and fixing bolts are distributed around the outer wall of the fixing ring 8, and threaded holes for the fixing bolts are provided on the outer surfaces of the upper tank 11 and the lower tank 12 respectively, when the purification tank 10 has been used for a long time and a large amount of pollutants have accumulated inside, requiring cleaning, the upper tank 11 and the lower tank 12 can be disassembled by loosening the fixing bolts, and the interiors of the upper tank 11 and the lower tank 12 can be thoroughly cleaned separately. After cleaning, the upper tank 11 and the lower tank 12 can be reassembled using the fixing bolts to restore the normal use of the purification tank 10.
