[0002] During the desulfurization and denitrification operations, the use of sulfur dioxide sensors can accurately measure the sulfur dioxide concentration at the inlet and outlet of the desulfurization and denitrification system in real time, and promptly feed back the data to the operator or the automatic control system.

[0046] It should be noted here that: during the rotation of the installation shaft 801, the drive shaft 1102 is rotated through the transmission between the belt 1202 and the two sets of pulleys 1201. During the rotation of the drive shaft 1102, the filter plate 902 is pushed to move inside the operating box 901 through the counteraction between the cam 1103 and the push rod 1101.

[0047] Preferably, multiple groups of mounting components are arranged inside the outlet pipe 302, and the multiple groups of mounting components are arranged in a state of annular display, and the mounting components include a clamping plate 401 arranged inside the outlet pipe 302, and the front side of the clamping plate 401 is provided with an arc groove 402 for clamping against the outer side of the sulfur dioxide sensor 2, and the inside of the outlet pipe 302 is provided with a telescopic component for telescopically connecting the clamping plate 401; the front side of the clamping plate 401 is provided with an inclined surface 403 for abutting the end of the sulfur dioxide sensor 2.

[0048] It should be noted here that: the sulfur dioxide sensor 2 is installed inside the exhaust pipe 302. During the installation process, the front end of the sulfur dioxide sensor 2 is pushed toward the middle position of each group of clamps 401. During the pushing process, the front end of the sulfur dioxide sensor 2 is abutted against the inclined surface 403 on each group of clamps 401, pushing each group of clamps 401 to move away from each other. When the sulfur dioxide sensor 2 is between the groups of clamps 401, the second spring 503 on the telescopic component pushes the clamps 401 to make the arc groove 402 on the front side of each group of clamps 401 abut against the outer side of the sulfur dioxide sensor 2. Through the abutment and extrusion effect, the sulfur dioxide sensor 2 is installed and fixed inside the exhaust pipe 302.

[0049] Preferably, the telescopic assembly includes a plurality of sleeves 501 fixed inside the air outlet pipe 302, a slide bar 502 is slidably connected to the sleeve 501, one end of the slide bar 502 is fixed to the clamping plate 401, a second spring 503 is sleeved on the outer side of the sleeve 501, and both ends of the second spring 503 are respectively connected to the clamping plate 401 and the inner wall of the air outlet pipe 302;

[0050] It should be noted that: the sleeve 501 and the slide rod 502 are used to assist the extension and retraction movement of the clamping plate 401 after the force is applied, and the second spring 503 is used to squeeze and push the clamping plate 401 after the contraction movement.

[0051] In this scheme: a sensor protection assembly for detecting desulfurization and denitrification operations includes the following steps:

[0052] When the sulfur dioxide sensor 2 is used to identify and detect the sulfur dioxide content of the gas generated during the desulfurization and denitrification operation, the sulfur dioxide sensor 2 is installed inside the outlet pipe 302. During the installation process, the front end of the sulfur dioxide sensor 2 is pushed toward the middle position of each group of clamps 401. During the pushing process, the front end of the sulfur dioxide sensor 2 is against the inclined surface 403 on each group of clamps 401, pushing each group of clamps 401 to move away from each other. When the sulfur dioxide sensor 2 is between the groups of clamps 401, the second spring 503 on the telescopic component pushes the clamps 401 against each other, so that the arc groove 402 on the front side of each group of clamps 401 is against the outer side of the sulfur dioxide sensor 2. Through the against extrusion effect, the sulfur dioxide sensor 2 is installed and fixed inside the outlet pipe 302;

[0053] After the sulfur dioxide sensor 2 is installed, the gas to be detected is transported to the inside of the circular installation cover 101 through the air inlet pipe 301 and discharged from the circular installation cover 101 through the air outlet pipe 302. During the gas circulation process, the sulfur dioxide content in the gas is detected by the sulfur dioxide sensor 2. In the process of the gas passing through the circular installation cover 101, the transported gas to be detected is processed by the alkaline filter material inside the storage chamber inside the circular frame 6 that is connected to the air inlet pipe 301 and the air outlet pipe 302. The hydrogen chloride and sulfuric acid mist contained in the gas are neutralized and removed by the alkaline filter material to avoid damage to the sulfur dioxide sensor 2 caused by the hydrogen chloride and sulfuric acid mist in the detection gas, thereby protecting the sulfur dioxide sensor 2 during the detection process, facilitating the accurate detection operation of the sulfur dioxide sensor 2 during the desulfurization and denitrification operation. In addition, during the air intake transmission process, the dust and solid impurities in the intake air are intercepted and filtered by the filter plate 902 inside the operation box 901 to avoid the influence of dust and impurities on the detection of the sulfur dioxide sensor 2.

[0054] As the protective treatment proceeds, in order to ensure the protective treatment effect, the motor 802 is driven to drive the installation shaft 801 and the circular frame 6 to rotate. Through the rotation of the circular frame 6, the storage chambers at other positions on the circular frame 6 are connected to the inlet pipe 301 and the outlet pipe 302. The unused alkaline filter materials inside the other storage chambers can ensure the effect of neutralization treatment of hydrogen chloride and sulfuric acid mist in the gas. In the process of the rotation of the installation shaft 801, the transmission between the belt 1202 and the two sets of pulleys 1201 is used. The drive shaft 1102 is rotated. During the rotation of the drive shaft 1102, the filter plate 902 is pushed to move inside the operating box 901 through the counteraction between the cam 1103 and the push rod 1101. During the movement of the filter plate 902, the scraper 1301 and the surface of the filter plate 902 counteract each other to scrape and separate the dust and foreign matter adsorbed on the surface of the filter plate 902 after the filtering process, thereby ensuring the cleanliness of the filter plate 902 and further ensuring the effect of the filter plate 902 on the intake filtration process.
