[0041] Refer to Figures 11-14 , the adjusting mechanism includes a cylinder body 141, a rotating ring 142, a connecting rod 143, a first notched ring 144, a second notched ring 145, a slider 146, a spring 147, a fixed block 148, and an inclined block 149. Cylinder bodies 141 are connected to the middle of the bottoms of the connecting plates 134. Rotating rings 142 are rotatably connected to the bottoms of the cylinder bodies 141. The first rotating shafts 135 are located inside the cylinder bodies 141 and the rotating rings 142. A connecting rod 143 is commonly hinged to the adjusting rings on the three variable pressure nozzles 9 on the same mounting pipe 8. The connecting rod 143 is hinged to the rotating ring 142. First notched rings 144 are connected to the lower parts inside the cylinder bodies 141. Second notched rings 145 are connected to the tops of the first notched rings 144. Sliders 146 are slidably connected to the upper parts of the first rotating shafts 135. The sliders 146 are located in the notches of the first notched rings 144. Springs 147 are connected between the sliders 146 and the first rotating shafts 135. Fixed blocks 148 and inclined blocks 149 are connected to the front sides of the tops of the rotating rings 142. The fixed blocks 148 are located on the left side of the inclined blocks 149. The sliders 146 are located between the fixed blocks 148 and the inclined blocks 149. The sliders 146 are in contact with the inclined surfaces of the inclined blocks 149.

[0042] The staff removes the bolts on the connecting block 127, then removes the sealing plate 126, and then pulls the sliding frame 121 to the left. The sliding frame 121 is removed from the tower body 2 through the inlet / outlet 125, and the insertion block 133 is removed from the insertion sleeve 136. Subsequently, the packing is loaded into the wire mesh frame 124. The wire mesh frame 124 can be taken out of the sliding frame 121 to facilitate the replacement of the packing in the wire mesh frame 124. After the wire mesh frame 124 is filled with packing, the sliding frame 121 is pushed to the right. The sliding frame 121 enters the tower body 2 through the inlet / outlet 125, and the insertion block 133 is reinserted into the insertion sleeve 136. The inlet / outlet 125 is sealed with the sealing plate 126. The connecting block 127 on the sealing plate 126 and the connecting block 127 on the tower body 2 are connected by bolts to fix the sealing plate 126 on the tower body 2. Industrial waste gas is introduced into the tower body 2 through the inlet pipe 3. The industrial waste gas floats upward and contacts the packing. The inlet pipe 11 is connected to the absorbent liquid. The absorbent liquid flows into the annular pipe 6 and the installation pipe 8 through the inlet pipe 11 and the connecting pipe 10. Subsequently, the absorbent liquid is sprayed out through the atomizing nozzles 7 and the variable pressure nozzles 9 to spray the industrial waste gas. High-efficiency mass transfer between the industrial waste gas and the absorbent liquid is achieved through the packing to remove pollutants in the industrial waste gas, achieving the purpose of purifying the industrial waste gas. The purified industrial waste gas is discharged through the outlet pipe 4. When the packing needs to be cleaned, the inlet pipe 11 is connected to clean water. The clean water is sprayed out through the atomizing nozzles 7 and the variable pressure nozzles 9 to wash the packing. The dirty water is discharged through the drain pipe 5. The output shaft of the control motor 137 is rotated to drive the second rotating shaft 138 to rotate. The second rotating shaft 138 drives the first rotating shaft 135 to rotate through the pulley group. The first rotating shaft 135 drives the rotating sleeve 131 to rotate through the insertion sleeve 136 and the insertion block 133. The rotating sleeve 131 drives the stirring rod 132 to rotate. The stirring rod 132 stirs the packing in the wire mesh frame 124 to make the packing move, ensuring that the scale on the packing can be removed more thoroughly. The rotation of the first rotating shaft 135 can also drive the slider 146 to rotate. At this time, the second notch ring 145 limits the slider 146, making the slider 146 unable to move upward. The slider 146 pushes the inclined block 149, causing the inclined block 149 to rotate. The inclined block 149 drives the rotating ring 142 to rotate. The rotating ring 142 drives the adjusting ring on the variable pressure nozzle 9 to rotate through the connecting rod 143 to adjust the pressure of the variable pressure nozzle 9, so that the variable pressure nozzle 9 sprays a water column to ensure that the clean water can wash the packing clean, and there is no need to disassemble the tower body 2 and no need for long-term shutdown, ensuring the working efficiency. When the inclined block 149 contacts the first notch ring 144, the notch of the slider 146 will correspond to the notch of the second notch ring 145. The inclined block 149 stops rotating, and the slider 146 continues to rotate. The slider 146 moves upward along the inclined surface of the inclined block 149 to the top of the second notch ring 145, and the spring 147 is compressed. The slider 146 rotates along the top of the second notch ring 145 to ensure that the stirring rod 132 can rotate normally. After the packing cleaning is completed, the output shaft of the control motor 137 rotates in the reverse direction to drive the second rotating shaft 138 to rotate in the reverse direction.The second rotating shaft 138 drives the first rotating shaft 135 to rotate in the reverse direction through a pulley group. The first rotating shaft 135 drives the slider 146 to rotate in the reverse direction. When the slider 146 corresponds to the notch of the second notch ring 145, under the action of the spring 147, the slider 146 moves downward between the fixed block 148 and the inclined block 149. The slider 146 will push the fixed block 148, causing the fixed block 148 to rotate. The fixed block 148 drives the rotating ring 142 to rotate in the reverse direction. The rotating ring 142 drives the adjusting ring on the variable pressure nozzle 9 to rotate in the reverse direction through the connecting rod 143, adjusting the pressure of the variable pressure nozzle 9, so that the variable pressure nozzle 9 sprays water mist.

[0043] Refer to Figure 15 and Figure 16 It also includes a positioning shaft 151. The upper part inside the sliding frame 121 is circumferentially and evenly spaced with positioning shafts 151 connected. The upper part of the wire mesh frame 124 is circumferentially and evenly spaced with positioning holes 152 opened. When the wire mesh frame 124 is placed inside the sliding frame 121, the positioning shafts 151 will be inserted into the positioning holes 152, so as to be able to position the wire mesh frame 124 and prevent the wire mesh frame 124 from moving together with the packing.

[0044] Refer to Figure 17 and Figure 18 It also includes a mounting ring 161, a mounting rod 162 and a conical plate 163. The lower part inside the tower body 2 is connected with the mounting ring 161. Three mounting rods 162 are circumferentially and evenly spaced and connected inside the mounting ring 161. The conical plates 163 are evenly spaced and connected on the three mounting rods 162. When the industrial waste gas floats upward, it will pass through the conical plates 163. The conical plates 163 can disperse the industrial waste gas, increase the contact area between the industrial waste gas and the absorption liquid, and improve the removal rate of pollutants.

[0045] Refer to Figure 2 It also includes a sealing ring 17. The sealing rings 17 are connected to both the upper and lower sides inside the tower body 2. The bottom of the sealing ring 17 contacts the top of the sliding frame 121. The sealing ring 17 can improve the sealing performance between the tower body 2 and the sliding frame 121 and prevent the absorption liquid from leaking.

[0046] Refer to Figure 1 It also includes an observation window 18. Three observation windows 18 are sequentially connected from top to bottom on the front side of the tower body 2. Through the observation window 18, the spraying situation of the industrial waste gas and the flushing situation of the packing can be observed, so as to carry out subsequent operations.

[0047] Refer to Figure 1 It also includes a staircase frame 19. The staircase frames 19 are connected to both the front and back sides of the frame 1 through bolts. It is possible to climb to the top of the frame 1 through the staircase frame 19, which is convenient for inspecting and maintaining the tower body 2.

[0048] Refer to Figure 2, further comprising a wet and dry separator 20, the wet and dry separator 20 is installed at the upper part inside the tower body 2 by bolts, and the wet and dry separator 20 can perform wet and dry separation on the purified industrial waste gas to ensure that the purified industrial waste gas can reach a higher dryness.
