Description

Technical Field

[0001] The present invention relates to the technical field of air pollution monitoring, and in particular to a high-precision air pollutant monitoring sensor device. Background Art

[0002] In recent years, with the acceleration of urbanization and the in-depth development of industrialization, the problem of air pollution has become increasingly prominent. In order to achieve real-time monitoring of pollutants in the air and help improve the urban ecological environment, air pollutant monitoring sensor equipment has been widely used.

[0003] Atmospheric pollutant monitoring sensors are not only used in urban environmental monitoring, but also cover multiple fields such as traffic pollution monitoring and industrial emission monitoring. In the field of industrial emission monitoring, for example, when industrial flue gas is discharged into the atmosphere through chimneys, atmospheric pollutant monitoring sensors are needed to strictly monitor the pollutants in the flue gas to ensure that the pollutant content is within the prescribed emission standards. At the same time, industrial chimneys are not always in a smoke exhaust state. When the chimney is not exhausting smoke, the monitoring sensor also needs to collect air in the background environment for monitoring in order to evaluate the ambient air quality. If the same sampling pipeline is used when the chimney is not exhausting smoke and when it is exhausting smoke, the residual gas collected in the previous stage will interfere with the monitoring results of the next stage, thereby affecting the reliability of the monitoring data.

[0004] At the same time, in addition to common pollutants, the gas discharged from the chimney also contains a certain amount of tar components. During the use of the atmospheric pollutant monitoring sensor equipment, the tar will gradually adhere to the sampling pipe of the sensor. At the same time, due to the high height of the chimney, the daily maintenance of the sensor equipment installed at the chimney exhaust port is more difficult, and the sampling pipe cannot be cleaned in time, which will cause a thick layer of sediment to form on the inner wall of the sampling pipe, causing the sampling pipe to be blocked and affecting the sampling flow. At the same time, impurities in the accumulated oil will also affect the monitoring results and affect the accuracy of the monitoring results.

[0005] Therefore, a high-precision atmospheric pollutant monitoring sensor device is proposed. Summary of the invention

[0037] The liquid in the liquid storage tank 31 is cleaning liquid, and the tops of the symmetrically arranged cleaning scrapers 310 are respectively in contact with the inner walls of the first gas sampling pipe 28 and the second gas sampling pipe 29 .

[0038] The above implementation works as follows:

[0039] The initialization steps are as follows:

[0040] In the initial state, the driving fan 23 is in a stationary state, the rain shield on the top of the first gas collection pipe 28 is not in contact with the top of the monitoring box 21, the rain shield on the top of the second gas collection pipe 29 is in contact with the top of the monitoring box 21, and the linkage baffle 33 blocks the connection between the liquid storage tank 31 and the connecting hose 36.

[0041] The working steps are as follows:

[0042] The following is an explanation of the process of switching components to switch the atmospheric pollutant sampling ports:

[0043] like Figures 2 to 6 As shown, when the chimney body 1 starts to discharge smoke to the outside, since the driving fan 23 is located inside the chimney body 1, when the smoke discharged from the inside of the chimney body 1 flows along the surface of the driving fan 23, a pressure difference is generated on the surface of the blades. This pressure difference generates a thrust on the fan blades, which drives the driving fan 23 to start rotating. Then, in the process of the chimney body 1 continuously discharging smoke, the driving fan 23 continues to rotate. The rotation of the driving fan 23 drives the rotating main shaft 22 fixedly connected thereto to rotate inside the monitoring box 21. The rotation of the rotating main shaft 22 drives the rotating circular block 24 fixedly connected thereto to rotate synchronously. The rotation of the rotating circular block 24 will clamp the internal The block 27 applies centrifugal force. The centrifugal force is an inertial force presented in a rotating reference system. It always points to the outside of the rotation axis and makes the object tend to move away from the rotation center. Therefore, during the rotation of the rotating circular block 24, the clamping block 27 slides in the direction away from the center of the rotating circular block 24 in the sliding groove 25 and stretches the linkage spring 26. At the same time, due to the restriction of the groove wall of the sliding groove 25, the clamping block 27 slides linearly in the sliding groove 25. When the clamping block 27 slides in the sliding groove 25 to the outside of the rotating circular block 24, the clamping block 27 will be in contact with the linkage rack 210 during the rotation of the rotating circular block 24. The rotation of the clamping block 27 drives the first gas collection pipe 28 to move downward through a linkage rack 210 fixedly connected to the first gas collection pipe 28. The downward movement of the first gas collection pipe 28 will compress a corresponding switching spring 218. At the same time, the second gas collection pipe 29 is driven to move upward through a linkage rack 210 fixedly connected to the second gas collection pipe 29. The upward movement of the second gas collection pipe 29 will stretch a corresponding switching spring 218. When the movement of the first gas collection pipe 28 and the second gas collection pipe 29 causes the clamping block 27 to mesh with the sliding block 213, the rotation of the clamping block 27 pushes the sliding block 213 on the guide rod 21 2 slides and compresses the reset spring 214. When the clamping block 27 rotates and the clamping block 27 no longer fits the sliding block 213, the sliding block 213 slides and resets on the surface of the guide rod 212 under the elastic extension of the reset spring 214. Then, during the rotation of the clamping block 27, the sliding block 213 continuously repeats the above process, and the rotation of the clamping block 27 is not hindered. At this time, the rain shield on the top of the first gas collection pipe 28 fits with the top of the monitoring box 21, and the rain shield on the top of the second gas collection pipe 29 does not fit with the top of the monitoring box 21. The monitor 219 collects and detects the smoke discharged from the chimney body 1 through the second gas collection pipe 29.

[0044] When the chimney body 1 stops working and no longer discharges smoke, the driving fan 23 stops rotating and the rotating round block 24 stops rotating. At this time, the clamping block 27 is no longer subjected to the centrifugal force. Under the elastic contraction of the linkage spring 26, the clamping block 27 slides along the sliding groove 25 to the inside of the rotating round block 24. At this time, the clamping block 27 is no longer meshed with the sliding block 213 and the linkage rack 210. Under the elastic extension of a switching spring 218 corresponding to the first gas collection pipe 28, the first gas collection pipe 28 slides upward inside the monitoring box 21. Under the elastic contraction of a switching spring 218 corresponding to the second gas collection pipe 29, the second gas collection pipe 29 slides downward inside the monitoring box 21. At this time, the rain shield on the top of the first gas collection pipe 28 is not in contact with the top of the monitoring box 21. The rain shield on the top of the second gas sampling pipe 29 fits with the top of the monitoring box 21. The monitor 219 collects and detects atmospheric pollutants through the first gas sampling pipe 28. When the chimney main body 1 does not exhaust gas, the first gas sampling pipe 28 is used to collect ambient air that does not contain emissions for detection, which can be used as a benchmark for subsequent data comparison. When the chimney main body 1 discharges flue gas, the second gas sampling pipe 29 is used to collect samples containing emissions. The atmospheric pollutant sampling tube can be switched according to whether flue gas is discharged from the chimney main body 1, thereby avoiding cross-contamination between emissions and ambient air that does not contain emissions, thereby ensuring the accuracy of the test results. At the same time, when the sampling tube is switched, the unused sampling tube is stored in the monitoring box 21, so that the unused sampling tube will not be contaminated by dust and impurities, thereby extending the service life of the equipment.

[0045] The following is a description of the cleaning process of the air pollutant sampling tube using the cleaning component:

[0046] like Figures 3 to 9As shown, during the sliding switching of the first gas collection pipe 28 and the second gas collection pipe 29, when the first gas collection pipe 28 slides downward, the downward sliding of the first gas collection pipe 28 drives the linkage gear rod 35 fixedly connected thereto to move downward, and the downward movement of the linkage gear rod 35 drives the linkage gear 34 meshing with it to rotate, and the rotation of the linkage gear 34 drives the linkage baffle 33 fixedly connected thereto to rotate synchronously, and the rotation of the linkage baffle 33 makes the liquid storage tank 31 and the interior of the connecting hose 36 communicate with each other, and the cleaning liquid in the liquid storage tank 31 enters the interior of the liquid guide shell 215 through the connecting hose 36, and at the same time, the upward sliding of the second gas collection pipe 29 drives the linkage gear 34 meshing with it to rotate synchronously. The second connecting rod 316 fixedly connected thereto moves upward synchronously. The upward movement of the second connecting rod 316 drives a linked worm 39 corresponding to the first gas production pipe 28 to move upward. The upward movement of the linked worm 39 drives the cleaning scraper 310 to slide upward inside the first gas production pipe 28. Because the top of the cleaning scraper 310 is in contact with the inner wall of the first gas production pipe 28, the upward movement of the cleaning scraper 310 can scrape off the oil stains adhered to the inner wall of the first gas production pipe 28. At the same time, the scraped oil stains slide into the interior of the linked worm 39 along the inner wall of the cleaning scraper 310, and then enter the interior of the collection box 37 through the linked worm 39.

[0047] In addition, the upward movement of the linkage worm 39 drives the cleaning sponge 311 to move upward into the interior of the first gas production pipe 28. During the upward movement of the cleaning sponge 311, the cleaning liquid in the liquid guide shell 215 enters the interior of the cleaning sponge 311 through the flow holes arrayed on the liquid guide shell 215 to infiltrate the cleaning sponge 311. At the same time, because the linkage worm 39 is threadedly connected to the thread groove 38, when the linkage worm 39 moves upward, the linkage worm 39 rotates inside the thread groove 38. The rotation of the linkage worm 39 drives the cleaning sponge 311 to rotate synchronously. Therefore, the cleaning sponge 311 will rotate into the interior of the first gas production pipe 28, and wipe the oil stains on the inner wall of the first gas production pipe 28, and then cooperate with the cleaning scraper 310 to scrape the inner wall of the first gas production pipe 28, further ensuring the cleanliness of the inner wall of the first gas production pipe 28. When the first gas production pipe 28 moves to the bottom, the linkage baffle 33 rotates one circle to seal the connection between the liquid storage tank 31 and the connecting hose 36 again.

[0048] When the first gas collection pipe 28 slides upward, the upward movement of the first gas collection pipe 28 drives the linkage gear rod 35 fixedly connected thereto to move upward, and the upward movement of the linkage gear rod 35 drives the linkage gear 34 meshing with it to rotate, and the rotation of the linkage gear 34 drives the linkage baffle 33 fixedly connected thereto to rotate synchronously, and the rotation of the linkage baffle 33 makes the liquid storage tank 31 and the interior of the connecting hose 36 communicate with each other, and the cleaning liquid inside the liquid storage tank 31 enters the interior of the liquid guide shell 215 through the connecting hose 36. At the same time, the downward sliding of the second gas collection pipe 29 drives the second connecting rod 316 fixedly connected thereto to move downward synchronously, and the downward movement of the second connecting rod 316 drives a linkage worm 39 corresponding to the first gas collection pipe 28 to rotate and move downward inside the thread groove 38, and the linkage worm The downward movement of the rod 39 drives the cleaning sponge 311 to move downward and away from the interior of the first gas production pipe 28. During the downward movement of the cleaning sponge 311, the cleaning liquid inside the liquid guiding shell 215 enters the interior of the cleaning sponge 311 through the flow holes arrayed on the liquid guiding shell 215 to soak the cleaning sponge 311. At the same time, during the downward rotation of the cleaning sponge 311, the cleaning sponge 311 fits against the first pressing block 312 and the second pressing block 314. The first pressing block 312 squeezes the cleaning sponge 311 to squeeze out the sewage inside the cleaning sponge 311. The squeezed sewage enters the interior of the collecting box 37 through the connecting block 313, thereby ensuring the cleaning of the cleaning sponge 311, extending the service life of the cleaning sponge 311, and ensuring the cleaning effect of the cleaning sponge 311.

[0049] Similarly, during the movement of the second gas sampling tube 29, the cleaning scraper 310 and the cleaning sponge 311 corresponding to the second gas sampling tube 29 can synchronously complete the cleaning of the second gas sampling tube 29, and then during the switching of the sampling tube, the maintenance and cleaning of the sampling tube can be synchronously completed, thereby extending the service life of the monitoring box 21 and reducing the frequency of manual maintenance of the monitoring box 21. At the same time, it also avoids the clogging of the sampling tube due to the accumulation of oil and dirt in the sampling tube, ensures the sampling flow and sample concentration, and avoids the influence of impurities in the sampling tube on the detection results.
