[0043] Example 2

[0044] Reference Figure 2 , 6 , 7, 8, this embodiment is different from the first embodiment in that: an outlet pipe 6 is provided at one end of the shunt pipe 5, one end of the camera 7 is installed on one side of the outlet pipe 6, a collar 33 is rotatably connected between the outlet pipe 6 and the shunt pipe 5 and between the first connecting elbow 9 and the shunt pipe 5, and a plug rod 32 is installed on one side of the two collars 33, one end of the two plug rods 32 is movably sleeved with the same baffle 31, the center position of the baffle 31 is adapted to the distance between the centers of the two collars 33, a spring 30 is installed at the bottom of the baffle 31, and the bottom of the spring 30 is installed on the top of the base 1, the spring 30 is always in a stretched state, and two fixed blades 35 and movable blades 34 are provided, and the two movable blades 34 They are rotatably connected in the two rings 33 respectively, one end of the two fixed blades 35 is installed with a fixing plate 36, and the two groups of fixing plates 36 are respectively installed on the inner walls of the air outlet pipe 6 and the first connecting elbow 9, one side of the first connecting elbow 9 is rotatably connected with a support rod 28, and one end of the support rod 28 is located at the bottom of the baffle 31, and the other end of the support rod 28 is provided with a slide groove 29, one end of the pressure rod 21 movably passes through one end of the slide groove 29 and extends to the outside, the pressure rod 21 descends, drives one end of the support rod 28 to descend, and makes the other end rise, so that the baffle 31 rises, and when the baffle 31 rises, the ring 33 is driven to rotate through the insertion rod 32, thereby driving the movable fan blades 34 to rotate, at this time the air outlet pipe 6 is blocked, and the return pipe 10 is connected.

[0045] Reference Figure 5A guide block 24 is installed on the top of the base 1, and a guide groove 25 is opened on the side of the guide block 24 close to the pressure rod 21. The width of the guide groove 25 is adapted to the cross-sectional diameter of the pressure rod 21. One end of the pressure rod 21 is slidably connected to the inside of the guide groove 25. The top and bottom of the guide groove 25 are rotatably connected to guide plates 26. A torsion spring 27 is installed at the connection between the guide plate 26 and the guide groove 25. When the pressure rod 21 rises under the action of the guide plate 26 and the guide groove 25, it moves along the outside.

[0046] The rest of the structure is the same as that of Example 1.

[0047] Operation process: during use, the movable blades 34 and the fixed blades 35 located at the air outlet pipe 6 are opened, and the movable blades 34 and the fixed blades 35 located at the first connecting elbow 9 are closed. The gas enters through the air inlet 2 and is purified by the washing tower 3. The purified gas enters the diversion pipe 5 after passing through the delivery pipe 4. At the same time, the detector 8 detects the pH value of the gas. The staff observes the reading of the detector 8 through the camera 7. When the value is within the normal threshold range, the gas is discharged through the air outlet pipe 6. When the value is in an abnormal state, the staff starts the cylinder 18. The cylinder 18 descends and drives the connecting plate 19 to descend. The connecting plate 19 drives the pressure rod 21 to descend through the telescopic rod 20. When the pressure rod 21 descends, the baffle rod 16 is moved, and the fixed ring 15 is driven to rotate. The fixed ring 15 drives the scraper 14 to rotate, thereby scraping and cleaning the inner wall of the return pipe 10, and making the ash fall out through the opening groove 13. At the same time, the pressure rod 21 descends and drives one side of the support rod 28 When the air outlet pipe 6 is blocked, the return pipe 10 is connected, and the connecting plate 19 moves to the bottom and contacts the electrode 23, so that the fan 12 works. The fan 12 transports the gas to the washing tower 3 through the first connecting elbow 9, the return pipe 10 and the second connecting elbow 11 for re-washing. When the pH value tested is within the normal range, the cylinder 18 is raised, and the cylinder 18 drives the connecting plate 19 to leave the electrode 23, so that the fan 12 stops running. At the same time, the cylinder 18 moves the pressure rod 21 upward, and the pressure rod 21 moves along the outside through the guide groove 25 and staggers with the baffle rod 16. The pressure rod 21 causes the other end of the support rod 28 to drop through the slide groove 29. At this time, the elastic force of the spring 30 pulls the block to reset, thereby driving the two movable fan blades 34 to rotate, and the air outlet pipe 6 is opened and the return pipe 10 is closed.
