[0033] The gas-liquid mixing mechanism 100 includes a power assembly and a piston column 150. The power assembly is arranged on one side of the piston column 150. One end of the piston column 150 is fixedly connected to a spiral rod 151. The spiral rod 151 is rotatably connected to a rotating column 170. A mixing tank 160 is arranged on one side of the piston column 150. An extrusion cover 161 is fixedly connected to the piston column 150. A cross connection seat 180 and an annular nozzle 190 are fixedly connected to the top of the wastewater chamber 220. The cross connection seat 180 is fixedly connected to a spring telescopic rod 181. One end of the spring telescopic rod 181 is fixedly connected to a blocking bottom cover 182. A protrusion 171 is fixedly connected to the rotating column 170. The protrusion 171 is connected to the spiral rod 151. A plurality of stirring blades 172 are fixedly connected to the outer wall of the rotating column 170. When the spiral rod 151 descends, the protrusion 1 71 slides relative to the spiral rod 151 so that the rotating column 170 rotates relative to the spiral rod 151, and the rotating column 170 drives the stirring blade 172 to rotate and stir the clean water in the mixing tank 160 to accelerate the treatment of the exhaust gas. The inner wall of the mixing tank 160 is fixedly connected to the fixed collar 163, and the fixed collar 163 and the rotating column 170 are rotatably sleeved.

[0035] Specifically, clean water is first introduced into the clean water chamber 210 from the liquid inlet pipe 213 until the clean water level overflows the mixing tank 160, the gas-liquid mixing mechanism 100 is first put into working state, and then the exhaust gas is introduced into the mixing tank 160 through the exhaust gas inlet pipe 212 and the annular nozzle 190, the power assembly causes the piston column 150, the screw rod 151 and the extrusion cover 161 to descend relative to the mixing tank 160, and at the same time causes the rotating column 170 to rotate relative to the screw rod 151, when the extrusion cover 161 descends, the clean water and the exhaust gas inside the mixing tank 160 are pressurized, the mixing effect is enhanced, and thus the purification effect is improved, the rotating column 170 stirs the clean water by rotation so that it is mixed with the exhaust gas more fully, and the spring telescopic rod 181 pulls the sealing bottom cover 18 2 makes the blocking bottom cover 182 block the circular hole 223. When the spiral rod 151 descends to a certain height, the bottom of the spiral rod 151 pushes open the blocking bottom cover 182, so that the clean water that has purified the exhaust gas and the exhaust gas purified by the clean water are squeezed into the waste water chamber 220 from the mixing tank 160 through the circular hole 223 by the squeezing cover 161, and then the power assembly drives the piston rod 150, the spiral rod 151 and the squeezing cover 161 to rise, and at the same time, the clean water in the clean water chamber 210 flows into the mixing tank 160. This step is repeated for many times, and the waste liquid in the waste water chamber 220 flows out through the waste liquid outlet 221, and the purified exhaust gas in the waste water chamber 220 is sucked into the dry filter 320 by the exhaust fan 310 through the exhaust gas outlet 222.

The rotating shaft at one end of the second rotating rod 130 slides back and forth in the guide rail 111, and the guide rail 111 plays a guiding role. The second rotating rod 130 pulls one end of the third rotating rod 140 to make the other end of the third rotating rod 140 reciprocate up and down, thereby realizing the up and down reciprocating movement of the piston column 150, and the guide ring 211 is used to limit the vertical movement of the piston column 150.

[0038] like Figure 2As shown, in this embodiment, one end of the annular nozzle 190 passes through the mixing tank 160 and is fixedly connected to the exhaust gas inlet pipe 212.

[0039] In specific implementation, the exhaust gas flows into the annular nozzle 190 from the exhaust gas inlet pipe 212, and the exhaust gas is dispersed to multiple nozzles of the annular nozzle 190 and sprayed out, so that the exhaust gas and clean water are fully in contact.

[0040] In this embodiment, the blocking bottom cover 182 is close to the circular hole 223, the waste liquid outlet 221 is set at the bottom of one side of the wastewater chamber 220, and the exhaust gas outlet 222 is opened at the top of one side of the wastewater chamber 220 and is connected to the inside of the exhaust fan 310. The blocking bottom cover 182 blocks the circular hole 223, and the blocking bottom cover 182 can be opened by the spiral rod 151 descending to a certain height, so that the gas and liquid in the mixing tank 160 enter the wastewater chamber 220, the gas in the wastewater chamber 220 escapes from the exhaust gas outlet 222, and the liquid flows out from the waste liquid outlet 221.
