[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. A cleaning and detection component is provided. Water in the auxiliary water tank is extracted until the annular operation box is filled with water. The driving motor drives the winding wheel to rotate. The driving motor at the top ring reels the wire rope, and the driving motor at the bottom ring unwinds the wire rope, and pulls the annular operation box upward. During the upward movement, the cleaning motor is started to reciprocate. The cleaning motor drives the movable cotton strip and the positioning strip to reciprocate through the cleaning gear and the tooth groove to clean the outside of the tower body. The water in the annular operation box cooperates with the soaked fixed cotton strip to perform a scrubbing operation to remove the debris attached to the outside of the tower body to ensure the accuracy of subsequent detection;

[0022] In the process of pulling the annular operation box up and down, the first ultrasonic probe detects the thickness of the tower body and detects whether there are cracks and other conditions at the same time. Water is used as the detection medium between the tower body and the first ultrasonic probe to improve the accuracy of the detection. The upper side of the flue gas pipe of the tower body can be more accurately detected by moving the annular operation box up and down, with high detection accuracy. The lower side of the flue gas pipe of the tower body is at a lower position and can be manually detected, and then the entire tower body can be detected. The detection is simpler and can be operated without stopping the desulfurization tower or climbing for detection. The operation is more convenient and faster.

[0023] Two movable semi-rings are sleeved on the flue gas pipe and merged into a circular shape. The water supply valve is opened and the faucet is connected to fill the space in the movable semi-rings with water. The movable semi-rings are slowly rotated and moved along the flue gas pipe to merge into a circular shape. The second ultrasonic probe is used to detect the flue gas pipe and perform corrosion detection on the flue gas pipe to prevent the flue gas from being corroded and damaged and causing exhaust gas leakage. During the process of introducing flue gas, if the flue gas temperature is too high, water can be continuously introduced into the movable semi-rings merged into a circular shape. The internal water pressure continues to increase, which will squeeze the sealing semi-circular plug in the pressure hole to deform. Water flows out from the gap of the sealing semi-circular plug to the outside of the flue gas pipe to cool down the flue gas pipe and reduce the temperature of the flue gas through heat transfer, thereby preventing the flue gas temperature entering the tower body from being too high and affecting the desulfurization effect, which is more conducive to the desulfurization process.

[0024] 2. An internal detection component is provided. The operator climbs up the ladder to the position of the observation tube. During the climbing process, the sliding card is at the same height as the detection hole. After reaching the detection position, the rotating plate rotates with the rotating shaft as the center, the guide tube is aligned with the detection hole, and the pull-out rod is slid and installed in the guide tube. The pull-out rod is aligned with the connecting screw groove, and the air extraction hole is aligned with the docking hole. The pull-out rod is pushed along the guide tube until the camera and the lighting in the detection slot are inside the tower body. Turn on the camera and the lighting to take pictures to detect the corrosion position. If there is too much water mist or floating inside the tower body and it affects the detection, turn on the exhaust pump, and rely on the connected air extraction holes and docking holes to extract the gas in the tower body, discharge the water mist and floating, and facilitate clearer viewing. After finding the damaged position, turn the handle in the pull-out slot, remove the observation plate in the observation tube for maintenance, which is more convenient to find the damaged position, accurate operation, and more convenient for maintenance.

[0025] In summary, the observation tube and the observation plate are located on one end of the outer side of the tower body and do not extend beyond the outer side of the tower body. The outer side of the observation plate is a curved surface with the same curvature as the outer side of the tower body. Compared with the tower body with a traditional appearance, the internal detection component will not hinder the up and down movement of the annular operation box of the cleaning detection component. The cleaning detection component comprehensively detects the outside of the tower body and quickly finds the corrosion location, while the internal detection component has a more intuitive understanding of the status of the corrosion location. The two cooperate with each other to better detect the desulfurization tower and improve its anti-corrosion effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The working principle and use process of the present invention are as follows: before the smoke is introduced, two movable semi-rings 525 are sleeved on the smoke pipe 2, and the two movable semi-rings 525 are combined into a circular ring shape. The electromagnet 532 is started to attract the magnetic block 531, and the sealing semi-ring 528 is tightly attached to the outer side of the smoke pipe 2. The sealing semi-ring 528 is made of high-temperature resistant rubber material. The water supply valve 527 is opened and connected to the faucet, so that the space in the movable semi-ring 525 is filled with water, and the movable semi-ring 525 is slowly rotated and moved along the smoke pipe 2 to be combined into a circular shape. The second ultrasonic probe 526 is used to inspect the smoke pipe 2. The smoke pipe 2 is tested for corrosion to prevent the smoke pipe 2 from being corroded and damaged and causing exhaust gas leakage. During the process of introducing the smoke, if the smoke temperature is too high, water can be continuously introduced into the movable semi-ring 525 which is combined into a ring shape. The internal water pressure continues to increase, which will squeeze the sealing semi-circular plug 530 in the pressure hole 529 to deform. Water flows out from the gap of the sealing semi-circular plug 530 to the outside of the smoke pipe 2, cooling the smoke pipe 2 and reducing the temperature of the smoke through heat transfer, preventing the smoke temperature entering the tower body 1 from being too high and affecting the desulfurization effect, which is more conducive to the desulfurization process.

[0049] During the use of the desulfurization tower, the flue gas enters the tower body 1 through the flue gas pipe 2, and water is sprayed into the desulfurization tower through the spray pipe 4 to perform desulfurization operation. After long-term use, when it is necessary to detect the degree of corrosion, the water supply pump 521 is started to extract water from the auxiliary water tank 3, and the switch valve 534 is closed until the annular operation box 507 is filled with water. Due to the obstruction of the leak-proof gasket 509, only a small amount of water seeps out, and the drive motor 504 is started to drive the winding wheel 505 to rotate, and the drive motor 504 on the top ring 501 is wound. The steel wire rope 506 and the driving motor 504 in the bottom ring 502 unwind the steel wire rope 506 and pull the annular operation box 507 upward. During the upward movement, the cleaning motor 518 is started to reciprocate. The cleaning motor 518 drives the movable cotton strip 513 and the positioning strip 514 to reciprocate through the cleaning gear 519 and the tooth groove 515 to clean the outside of the tower body 1. The water in the annular operation box 507 cooperates with the soaked fixed cotton strip 512 to perform a scrubbing operation to remove the debris attached to the outside of the tower body 1, thereby ensuring the accuracy of subsequent detection;

[0050] After cleaning for a period of time, open the switch valve 534 of the filter box 523, discharge the sewage containing dust through the drainage hose 522, and discharge it after being filtered by the filter box 523, and then re-introduce clean water into the annular operation box 507 to keep the water clean and ensure the normal subsequent detection;

[0051] In the process of pulling the annular operation box 507 up and down, the thickness of the tower body 1 can be detected by the first ultrasonic probe 510, and whether cracks and other conditions occur at the same time. Water is used as a detection medium between the tower body 1 and the first ultrasonic probe 510 to improve the accuracy of the detection. Due to the existence of the anti-collision port 508, the spray pipe 4 will not be hit to affect the movement of the annular operation box 507. Therefore, the upper side position of the flue gas pipe 2 of the tower body 1 can be more accurately detected by the up and down movement of the annular operation box 507, and the detection accuracy is high. The lower side position of the flue gas pipe 2 of the tower body 1 is at a lower position, and manual detection can be performed, and then the entire tower body 1 can be detected. The detection is simpler, and the desulfurization tower can be operated without stopping, and there is no need to climb for detection. The operation is more convenient and quick;

[0052] The observation tube 601 and the observation plate 602 are located at one end of the outer side of the tower body 1 and do not extend beyond the outer side of the tower body 1. The outer side of the observation plate 602 is a curved surface with the same curvature as the outer side of the tower body 1, which will not hinder the up and down movement of the annular operation box 507. When the annular operation box 507 moves to the position of the drawing groove 603, a small amount of water will flow into the drawing groove 603, but it will not affect the detection.

[0053] After the cleaning inspection component 5 is inspected, if a serious corrosion position is found, the operation of the desulfurization tower is stopped, and the operator climbs up the ladder 503 to the position of the observation tube 601. During the climbing process, the sliding card 613 is pulled to slide along the ladder 503 at the same time, and the sliding card 613 and the inspection hole 605 are at the same height. After reaching the inspection position, the rotating plate 615 rotates with the rotating shaft 614 as the center of the circle, the guide tube 616 is aligned with the inspection hole 605, the sealing plug in the exhaust hole 608 is taken out, and the pull rod 617 is slidably installed in the guide tube 616, and the pull rod 617 is aligned with the connecting screw groove 607, and ensures that the exhaust hole 608 is aligned with the docking hole 618, and is pushed along the guide tube 616. Pull out the rod 617 until the camera 611 and the lighting lamp 612 in the detection slot 610 are both inside the tower body 1, turn on the camera 611 and the lighting lamp 612, and take pictures to detect the corrosion position. If there is too much water mist or floating inside the tower body 1 and it affects the detection, turn on the exhaust pump 619, and use the connected exhaust holes 608 and docking holes 618 to extract the gas in the tower body 1, and discharge the water mist and floating, so as to facilitate clearer viewing. After finding the damaged position, turn the pull handle 604 in the pull-out slot 603, and remove the observation plate 602 in the observation tube 601 for maintenance operations, which makes it easier to find the damaged position, perform precise operations, and facilitate maintenance.
