Technical Field
[0001] This utility model relates to the field of flue gas analyzer technology, specifically a filter device for a flue gas analyzer that is easy to disassemble. Background Technology
[0002] There are two common working principles for flue gas analyzers: one is the electrochemical working principle, and the other is the infrared working principle. Portable flue gas analyzers on the market usually combine these two principles. Flue gas analyzers usually need to be used with a probe rod. The probe rod is inserted into the pipe, and the flue gas enters the analyzer through the probe rod for analysis.
[0003] A search revealed the following patent: CN214680749U, which discloses a flue gas analyzer filter. The filter includes a filter body with a baffle at its upper end. One side of the baffle has a through hole, while the other side does not. A partition is vertically mounted on the baffle, separating the side with the through hole from the side without. A vent is provided between the top of the partition and the top wall of the filter body. This flue gas analyzer filter has a simple structure, reasonable design, and is easy to use.
[0004] However, the following situation still occurs during the use of this device: Since the device uses a baffle to separate the through holes on the baffle to reduce the amount of water vapor in the flue gas entering the outlet pipe, the baffle alone cannot effectively block the water vapor in the flue gas, and the baffle cannot be quickly disassembled. After long-term use, a lot of particulate matter and pollutants will adhere to the baffle, which will affect the filtration of the flue gas and the analysis accuracy of the flue gas analyzer.

Detailed Implementation
[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0025] Please see Figures 1-5 As shown, a filter device for a dust analyzer that is easy to disassemble includes a filter body 1. The filter body 1 has a hollow internal structure. A drain hole is provided at the bottom of the filter body 1, and an air inlet pipe 2 is provided at the top of the filter body 1. The bottom of the air inlet pipe 2 passes through the filter body 1 and extends into its interior. The air inlet pipe 2 is connected to a water pipe to inject water into the interior of the filter body 1. After water injection, the air inlet pipe 2 is connected to a flue gas pipe to discharge flue gas into the water inside the filter body 1 for filtration. An air outlet pipe 6 is provided at the top of the filter body 1. An analyzer body 7 for analyzing flue gas is fixedly connected to the end of the air outlet pipe 6 away from the filter body 1. The analyzer body 7 is an existing structure and will not be described in detail. A sliding groove 22 is provided at the top of the filter body 1. The inner surface of the sliding groove 22... The filter body 1 is connected to the interior of the filter body 1. A drying plate 3 is slidably connected inside the sliding groove 22. The top of the drying plate 3 is provided with a handle for easy pulling. The drying plate 3 has multiple mesh holes for flue gas discharge. At the same time, the interior of the drying plate 3 contains activated carbon and other materials, which can adsorb water vapor in the flue gas and effectively reduce the impact of high water content in the flue gas on the detection results of the analyzer body 7. A baffle 8 is fixedly connected to the inner wall of the filter body 1. A protective shell 9 is fixedly connected to the top of the baffle 8. A motor 10 is installed inside the protective shell 9. A power supply, wires, controller and microcomputer structure are matched with the motor 10. Since the motor 10 is not a major structure, it will not be described in detail. The output end of the motor 10 rotates through the baffle 8 and extends to its outside. A power adjustment device is provided at the output end of the motor 10.
[0026] Please refer to Figure 2 The power adjustment device includes a rotating rod 11. The top of the rotating rod 11 is fixedly connected to the output end of the motor 10. Multiple disturbance rods 20 for disturbance are fixedly connected to the surface of the rotating rod 11. A connecting rod 12 is fixedly connected to the bottom of the rotating rod 11. Scrapers 13 are fixedly connected to both ends of the connecting rod 12. The scraper 13 has an inclined surface on the side near the inner wall of the filter body 1. The inner wall of the filter body 1 can be scraped and cleaned by the scraper 13.
[0027] The operator starts the motor 10 through the controller and microcomputer structure. The output end of the motor 10 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the disturbance rod 20 to rotate. The disturbance rod 20 can disturb the water inside the filter body 1. By disturbing the water inside the filter body 1, the water can form turbulence or circulation, thereby increasing the contact area and time between flue gas and water, improving the efficiency of pollutant dissolution, absorption and capture, improving the flue gas purification effect, and enhancing the water's ability to absorb dissolved pollutants in the flue gas. At the same time, it also helps to reduce the accumulation of sediment at the bottom of the filter body 1.
[0028] The rotating rod 11 drives the scraper 13 to rotate through the connecting rod 12. The scraper 13 can scrape and clean the inner wall of the filter body 1. By cleaning the inner wall of the filter body 1 with the scraper, the pollutants attached to the inner wall can be scraped off in time, reducing the formation of deposits and avoiding affecting the filtration effect, thereby extending the service life of the equipment, keeping the inner wall clean, reducing the frequency of manual cleaning, improving the continuous operation capability of the equipment, reducing maintenance costs, and ensuring the long-term stable operation of the system.
[0029] Please refer to Figure 2 The baffle 8 has an air outlet 15 extending to the outside. The air outlet 15 is connected to the interior of the filter body 1. The filtered flue gas can be discharged through the air outlet 15. The top of the baffle 8 has a slot 14. The drying plate 3 is inserted into the slot 14. The slot 14 can limit the position of the drying plate 3 to keep it stable.
[0030] Please refer to Figure 3 The inner wall of the sliding groove 22 is fixedly connected with two symmetrical sealing strips 21. The drying plate 3 is located between the two sealing strips 21. By making the two sealing strips 21 fit tightly against the two sides of the drying plate 3, the sliding groove 22 can be sealed, reducing the leakage of flue gas from the sliding groove 22. The drying plate 3 has a fixed groove 16 extending to its outside.
[0031] Please refer to Figure 5 A power block 4 is fixedly connected to the top of the filter body 1. A power groove 17 is opened inside the power block 4. A fixing block 18 is slidably connected inside the power groove 17. A protrusion 5 extending to the outside of the power block 4 is fixedly connected to the top of the fixing block 18. An inclined surface is provided on the top of the fixing block 18. The fixing block 18 is inserted into the inside of the fixing groove 16. A spring 19 is fixedly connected to one end of the fixing block 18. The end of the spring 19 away from the fixing block 18 is fixedly connected to the inner wall of the power groove 17. By moving the fixing block 18, the spring 19 can be compressed and reset.
[0032] The operator slides the drying plate 3 into the sliding groove 22 by holding the handle on the drying plate 3. The bottom of the drying plate 3 contacts the inclined surface of the top of the fixing block 18. The fixing block 18 slides under force and compresses the spring 19, continuing to slide the drying plate 3 into the filter body 1. The bottom of the drying plate 3 slides into the slot 14 and inserts, and the fixing block 18 slides into the fixing groove 16 and inserts. The spring 19 returns to its original position, which can quickly fix the drying plate 3. When the drying plate needs to be cleaned or replaced, the operator pulls the protrusion 5, and the fixing block 18 slides out of the fixing groove 16. The spring 19 is compressed under force, and then the operator pulls the handle on the drying plate 3, which can quickly disassemble and replace the drying plate 3. By quickly disassembling the drying plate 3, the replacement or cleaning time can be greatly shortened, avoiding long-term downtime of the equipment due to difficult disassembly and assembly, thereby improving the overall operating efficiency of the system and making it easier for operators to clean and maintain the drying plate 3, reducing the replacement frequency due to adsorption saturation or pollution accumulation, thereby reducing operating costs and extending the service life of the drying plate.
[0033] Working principle: The operator injects water into the filter body 1 by connecting the air inlet pipe 2 to the water pipe, and then connects the air inlet pipe 2 to the flue gas pipe to discharge the flue gas into the water. Then, through the controller and microcomputer structure, the motor 10 is started. The output end of the motor 10 drives the rotating rod 11 to rotate. The rotating rod 11 drives the agitator 20 to agitate the water inside the filter body 1, increasing the contact between the water and the flue gas, enabling rapid reaction and filtration. The inner wall of the filter body 1 is scraped and cleaned by the scraper. The filtered flue gas is discharged through the air outlet 15, then dried by the drying plate 3, and discharged through the mesh. Then, it enters the analyzer body 7 through the air outlet pipe 6 for analysis. When the drying plate 3 needs to be removed, the operator only needs to move the protrusion 5 to make the fixing block 18 slide out of the fixing groove 16 and make it contact the fixing, and then pull the handle on the drying plate 3 to remove it.
