[0028] In this embodiment, each interference mechanism includes a fixed sleeve 13, a threaded rod 14, a second trapezoidal block 15 and two limit rods 16.

[0029] In this embodiment, in order to facilitate maintenance personnel to screw the threaded rod 14 , a hexagonal block is fixedly sleeved on the threaded rod 14 .

[0030] In this embodiment, in order to fix the circular frame 5, a plurality of sockets 501 are provided on the outer ring of the circular frame 5, a fixing plate is fixedly installed on the bottom of the fixing ring 4, a locking screw 17 passes through and is threadedly installed on the fixing plate, and a latch is integrally formed with one end of the locking screw 17 close to the fixing tube 6, and the end of the latch away from the locking screw 17 extends to the corresponding socket 501.

[0031] In this embodiment, in order to limit the discharge pipe 9, a positioning slide is opened on the inner wall of the arc-shaped support plate 8, and a limiting strip 12 is fixedly installed on the top of the discharge pipe 9. The limiting strip 12 passes through the positioning slide and is slidably connected to the inner wall of the positioning slide.

[0032] The working principle of the chemical waste gas purification tower provided by the utility model is as follows:

[0033] When in use, the chemical waste gas enters the tower body 1 from the waste gas inlet pipe, and is initially purified after being adsorbed by the packing layer 2 below. After the purification liquid input pump is started, the waste gas purification liquid is discharged into the fixed cylinder 6 through the drainage pipe 3, and then the waste gas purification liquid enters multiple discharge pipes 9. Under the action of water pressure, the waste gas purification liquid is sprayed out through multiple nozzles 10 to absorb and neutralize harmful substances in the waste gas. Then, the waste gas is adsorbed and purified by the packing layer above, and then discharged to the outside of the tower body 1 through the waste gas discharge pipe;

[0034] When inspecting the nozzle 10 on the discharge pipe 9, first open the sealing plate on the inspection port 101, and then release the fixation of the discharge pipe 9 facing the inspection port 101. The specific operation is: use an open-end wrench to twist the threaded rod 14 counterclockwise. Since the second trapezoidal block 15 is limited by two limit rods 16, the threaded rod 14 will drive the second trapezoidal block 15 to move upward during the counterclockwise rotation. When the second trapezoidal block 15 moves to the top of the arc-shaped support plate 8, the discharge pipe 9 loses its resistance and shielding, and then the relevant maintenance personnel can remove it. The discharge pipe 9 is pulled out, and then the nozzle 10 on the discharge pipe 9 is inspected. After the nozzle 10 on the discharge pipe 9 is inspected, the locking screw 17 is rotated counterclockwise. During the counterclockwise rotation of the locking screw 17, it gradually moves in the direction of the inspection port 101, which drives the bolt to move, so that the bolt moves from the insertion hole 501 before withdrawal. In this way, the circular frame 5 is no longer restricted, and then the circular frame 5 is rotated to rotate other discharge pipes 9 to the inspection port 101, and then the same operation as above is used to remove the current discharge pipe 9;

[0035] After completing the inspection of all the nozzles 10, when reinstalling the discharge pipe 9, first insert the discharge pipe 9 into the arc-shaped support plate 8, and at the same time insert the limit bar 12 into the positioning slide, and then push the discharge pipe 9 in the direction of the fixed tube 6. Since the discharge pipe 9 is restricted by the arc-shaped support plate 8 and the positioning slide, it can be accurately inserted into the docking tube 7, and the first trapezoidal block 11 can ensure verticality. After the discharge pipe 9 is inserted in place, use a wrench to rotate the threaded rod 14 clockwise, and the clockwise rotating threaded rod 14 will drive the second trapezoidal block 15 to move downward, and then the discharge pipe 9 is inserted into the fixed tube 6. As the second trapezoidal block 15 descends, its inclined surface will fit with the inclined surface on the first trapezoidal block 11. During the subsequent descent of the second trapezoidal block 15, a thrust will be given to the first trapezoidal block 11. After the thrust acts on the discharge pipe 9, the discharge pipe 9 can be further moved toward the fixed tube 6 for a distance, and the contact with the sealing ring is tighter, so that the sealing between the discharge pipe 9 and the docking pipe 7 can be guaranteed. The installation process of the remaining discharge pipes 9 is the same as described above. After all the discharge pipes 9 are installed, they can be locked by using the locking screw 17 through the circular frame 5.

Through the arrangement of components such as a fixing ring 4, a circular frame 5, a fixing cylinder 6, a plurality of butt-jointed pipes 7, a plurality of arc-shaped supporting plates 8, a plurality of discharge pipes 9, and a plurality of nozzles 10, the rotating circular frame 5 can drive the plurality of discharge pipes 9 to rotate, so that the discharge pipes 9 can be conveniently adjusted to the inspection port 101, and it is convenient for relevant maintenance personnel to disassemble the discharge pipes 9.
