[0002] With rapid industrialization, waste gases emitted during industrial production have become a significant source of atmospheric pollution. These waste gases contain various harmful substances such as particulate matter, sulfur dioxide, and nitrogen oxides, posing a serious threat to the environment and human health. As environmental protection becomes increasingly important, the management of waste gas emissions is becoming more stringent. Polluting entities must ensure that their waste gases meet relevant standards before they can be discharged, thus requiring accurate and reliable monitoring methods to provide data support.

[0003] As shown in the prior art disclosed in CN221100690U, although the prior art uses a second filtration mechanism to block some of the larger solid particles in the pipeline, and the second filtration mechanism guides the exhaust gas to the exhaust gas sampling head of the device for sample extraction by guiding the flow of the smaller solid particles in the pipeline, and at the same time, during the exhaust gas guiding process, the exhaust gas changes its flow direction multiple times, causing most of the small particles in the exhaust gas to be adsorbed, thereby reducing the accumulation of small waste particles on the exhaust gas sampling head and ensuring the normal use of the exhaust gas sampling head. However, the filtration mechanism in the prior art needs to be disassembled for cleaning and maintenance, which requires the monitoring device to be shut down, thus affecting the efficiency of the monitoring device. Moreover, the overall disassembly and assembly steps are relatively cumbersome, requiring the entire flow box to be removed before the filtration mechanism can be disassembled and maintained.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Refer to the instruction manual appendix Figure 1-5 This utility model provides a device for monitoring exhaust gas pollutants in pipelines, including a detector body 1 for monitoring exhaust gas in the pipeline. The detector body 1 is provided with a sampling element for sampling exhaust gas in the pipeline, and the sampling element is provided with a filter element for blocking impurities. The filter element includes an assembly plate 2 located on the rear side of the detector body 1. The front side of the assembly plate 2 is provided with a filter ring 3 and two side plates 4. The filter ring 3 is located between the two side plates 4, and a cleaning brush 5 is installed on the side of the side plate 4 near the filter ring 3. The front side of the filter ring 3 is provided with a ring seat 6, and the rear side of the ring seat 6 is provided with an adjusting ring 7 movably connected by a bearing. The rear side of the adjusting ring 7 has a plurality of positioning grooves 8 arranged in a ring array, and the positioning grooves 8 are provided with positioning posts 9 for connecting the filter ring 3.

[0017] When using the aforementioned detector body 1 to detect pollutants in the exhaust gas inside the pipeline, the operator needs to install the sampling component on the detector body 1 inside the pipeline. Therefore, an installation ring 21 is fitted outside the ring seat 6, and the installation ring 21 has multiple mounting holes 22 arranged in a ring array on its exterior. In this way, after the sampling component is placed inside the pipeline, the connection stability between the installation ring 21 and the pipeline can be ensured by using fastening equipment and cooperating with the mounting holes 22, thereby guaranteeing the connection stability between the sampling component and the pipeline.

[0018] To prevent impurities in the exhaust gas from entering the sampling element and causing damage or blockage, a green ring inside the filter element can be used to intercept particulate matter in the exhaust gas. After the particulate matter is intercepted, the exhaust gas flows through the sampling element into the detector body 1. The sampling element includes a sample cylinder 15 located at the rear of the detector body 1. A sampling head 16 for connecting to the detector body 1 is installed inside the sample cylinder 15, and multiple spaced through holes 17 are opened on the outer rear end of the sample cylinder 15. The filter ring 3 and the ring seat 6 are both sleeved on the outside of the sample cylinder 15, and the mounting plate 2 is located at the rear of the sample cylinder 15. In this way, the filtered exhaust gas can flow through the through holes 17 into the sample cylinder 15, and the sampling head 16 is connected to the detector body 1, so that the exhaust gas can come into contact with the detector body 1 again through the sampling head 16, thereby realizing the monitoring of the exhaust gas in the pipeline.

[0019] Meanwhile, to ensure the blocking effect of the filter ring 3, it is necessary to prevent the filter ring 3 from clogging. Therefore, a connecting ring 10 with a T-shaped cross-section is installed at the rear end of the filter ring 3, and an annular groove 11 is opened on the front side of the assembly plate 2 corresponding to the connecting ring 10. The connecting ring 10 is located inside the annular groove 11. In this way, the filter ring 3 is movably connected to the assembly plate 2 by the movable engagement of the connecting ring 10 and the connecting groove, which facilitates the subsequent rotation of the filter ring 3. In addition, a driven gear 12 is sleeved on the outside of the adjusting ring 7. One end of the driven gear 12 meshes with a main gear 13. The front end of the main gear 13 is movably connected to the rear side of the ring seat 6 through a rotating shaft, and a handle 14 for driving the main gear 13 is provided on the front side of the ring seat 6. In this way, the main gear 13 can be rotated by turning the handle 14. The main gear 13 drives the adjusting ring 7 to rotate through the meshing driven gear 12. The adjusting ring 7 then drives the filter ring 3 to rotate through the engagement of the positioning pin 9 and the positioning groove 8. The filter ring 3 contacts the cleaning brush 5 during the reciprocating rotation. The cleaning brush 5 cleans the impurities adhering to the outside of the filter ring 3, avoiding the accumulation of impurities that may cause the filter ring 3 to become clogged, and ensuring the filtration effect of the filter ring 3 on impurities in the exhaust gas.

[0020] To prevent the assembly plate 2 from rotating with the filter ring 3, two limiting posts 19 are installed on the front side of the assembly plate 2. The two limiting posts 19 are respectively located on both sides of the fastening bolt 18, and a limiting groove 20 is opened on the rear end of the sample cylinder 15 corresponding to the limiting post 19. The limiting post 19 is located inside the limiting groove 20. In this way, the assembly plate 2 can be limited by the engagement of the limiting post 19 and the limiting groove 20, so as to ensure the stability of the assembly plate 2 and prevent the assembly plate 2 from rotating with the filter ring 3.

[0021] Furthermore, to facilitate maintenance of structures such as the filter ring 3, it is necessary to achieve convenient disassembly of the filter ring 3. Therefore, a fastening bolt 18 is provided on the rear side of the mounting plate 2. The front end of the fastening bolt 18 penetrates the mounting plate 2 and extends into the sample cylinder 15, and the fastening bolt 18 is threadedly connected to the sample cylinder 15. This allows the fastening bolt 18 to be disassembled and separated from the sample cylinder 15, freeing the mounting plate 2 from being restricted in its position, thereby facilitating the removal of structures such as the cleaning brush 5 and the filter ring 3, achieving convenient disassembly and maintenance.

[0022] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
