[0038] Please refer to Figure 1 , Figure 4 and Figure 5The surface of the connecting pipe 1 is provided with two pressure sensors 4, which are respectively located at the two ends of the filter screen 301. Through the arrangement of the pressure sensors 4, the pressure on both sides of the filter screen 301 can be monitored, and then it can be judged whether the filter screen 301 is blocked. The middle end of the connecting pipe 1 is provided with a control monitoring host 13, which can monitor the temperature and pressure of the gas in the pipe, and can also drive the external motor to rotate, so as to automatically clean the filter screen 301.

[0039] The GRS pipeline sulfur hexafluoride gas monitoring and impurity removal device in the embodiment can effectively reduce the impact of turbulence on the filter screen by expanding the filter contact area and combining with the airflow optimization design of the spiral flow guide groove 11, so as to ensure efficient passage of gas and achieve the purpose of filtering the gas.

[0040] It should be noted that the state of the sealing ring needs to be checked regularly to ensure the sealing performance of the flange.

[0041] The working principle of the above embodiment is as follows: when the gas enters through the left end of the connecting pipe 1, the spiral flow guide groove 11 rectifies the airflow and converts the turbulent flow into laminar flow, which is uniformly distributed to the surface of the circular truncated cone filter screen 301. The filter screen increases the contact area by using its gradually expanding structure to trap solid impurities in the gas. The purified gas flows to the right side of the pipeline. During the filtering process, the impurities attached to the inner wall of the filter screen gradually accumulate. When the pressure difference detected by the two pressure sensors 4 exceeds the set threshold, the control monitoring host 13 immediately starts the external motor to drive the power shaft 5 through the bevel gear 6 to rotate the cleaning shaft 302. The circumferentially arranged push pieces 303 rotate with the shaft, continuously scraping the inner wall of the filter screen, pushing the stripped impurities to the left end of the connecting ring 2 for temporary storage, avoiding clogging of the mesh holes. The temperature sensor 10 continuously collects the temperature data of the gas in the pipeline, and the control monitoring host 13 analyzes the state of the gas in real time in combination with the pressure difference feedback of the pressure sensor 4. The flange piece 7 is tightly fitted with the sealing ring through the sealing ring groove 12, so as to ensure that there is no gas leakage at the connection of the pipeline. When the purified gas flows through the sampling pipe 8 area, the valve 9 can be used to extract samples as needed for laboratory composition detection to verify whether the filtering effect meets the sulfur hexafluoride recovery standard.
