The number of the first liquid stirring rods 251 and the second liquid stirring rods 241 are the same and are linearly staggered.

[0038] like Figure 4-Figure 5 and Figure 8 As shown, it also includes a compression component, which includes a drive ring 26. The drive ring 26 is fixedly connected to the upper end of the second liquid stirring frame 24. A compression slip ring 27 is rotatably and slidably connected inside the drive ring 26. The compression slip ring 27 is circumferentially distributed with air leakage holes 271. One end of the air leakage hole 271 is in sliding contact with the liquid storage ring 17, and the other end is located at the bottom of the compression slip ring 27. The mounting circular plate 2 and the positioning circular plate 12 are respectively mirror-distributed with a first air vent and a second air vent. The mounting circular plate 2, the positioning circular plate 12, the U-shaped liquid storage cylinder 15, the drive ring 26, the compression slip ring 27 and the liquid cavity form a sealed compression cavity. A drive rod 261 is fixedly connected to the inner circumferential surface of the drive ring 26, and an elliptical compression slide groove 272 is opened on the outer circumferential surface of the compression slip ring 27. The drive rod 261 and the compression slide groove 272 are sleeved and slidably arranged.

[0039] In the initial state, the first motor 3 and the exhaust fan 11 are not turned on, the first liquid hole of the U-shaped liquid storage cylinder 15 and the third liquid hole of the liquid storage barrel 33 are offset and sealed with the second liquid hole of the sealing ring 32, and the absorption liquid is injected into the liquid inlet pipe 18 at this time, and the absorption liquid flows into the liquid storage ring 17 through the liquid inlet pipe 18, and the absorption liquid enters the shuttle hole 121 from the liquid storage ring 17 through the flow channel of the mounting circular plate 2, and the absorption liquid flows out along the cross-shaped groove of the shuttle hole 121 through the shuttle-shaped sealing block 19, and the absorption liquid flows downward along the connecting rod under the shuttle-shaped sealing block 19, and finally flows onto the buoyancy ball 20 and drips into the liquid cavity formed by the shell 1, the U-shaped liquid storage cylinder 15, the rotating drum 6 and the rotating circular plate 16.

[0040] Furthermore, when the liquid surface of the absorption liquid in the liquid cavity contacts the buoyancy ball 20, the absorption liquid exerts buoyancy on the buoyancy ball 20, causing the buoyancy ball 20 to move upward. The movement of the buoyancy ball 20 drives the shuttle-shaped sealing block 19 to slide upward along the shuttle-shaped hole 121 through the connecting rod, so that the upper end of the shuttle-shaped hole 121 is sealed by the shuttle-shaped sealing block 19, and the absorption liquid continues to be injected into the liquid storage ring 17 through the liquid inlet pipe 18 until the liquid storage ring 17 is filled with the absorption liquid. At this time, the absorption liquid flows into the liquid lifting cylinder 13 through the rectangular through hole at the bottom of the first liquid stirring frame 25, and flows into the rotating drum 6 through the circular hole in the middle of the rotating circular plate 16. The absorption liquid in the rotating drum 6 flows into the connected hose through the Venturi tube 7. At the same time, the absorption liquid flows into the Venturi tube 7 through the U-shaped groove of the U-shaped liquid storage cylinder 15, and further flows into the hose connected to the Venturi tube 7. At this time, the bottom of the liquid cavity is filled with liquid. At this time, the exhaust fan 11 is started, and the exhaust fan 11 draws the harmful waste gas from the breeding farm into the air inlet pipe 10. The harmful waste gas enters the diverter tube 8 from the air inlet pipe 10 and flows into the hose through the one-way valve 9. The absorption liquid in the hose is pushed out by the harmful waste gas, and the harmful waste gas and the absorption liquid are in contact with a large area in the venturi 7. The harmful waste gas flows horizontally to both ends along the internal T-shaped structure inside the venturi 7 and enters the liquid cavity, and slowly rises in the absorption liquid in the liquid cavity, and enters the gas in the liquid cavity to mix with it. The harmful waste gas is now waiting to be absorbed and processed by the absorption liquid.

[0041] Further, the first motor 3 is started, and the output shaft of the first motor 3 rotates clockwise to drive the auger 4 to rotate synchronously. At this time, the absorption liquid in the liquid cavity has flowed into the liquid lifting cylinder 13 through the rectangular through hole below the first liquid stirring frame 25. At this time, there is still gas in the liquid lifting cylinder 13 that has not been discharged when the absorption liquid is injected. The auger 4 continuously pushes the absorption liquid to rise in the liquid lifting cylinder 13 through rotation until the auger 4 discharges all the gas remaining in the liquid lifting cylinder 13 through the atomizing nozzle 14. The auger 4 continues to rotate to push the absorption liquid in the liquid lifting cylinder 13 into the atomizing nozzle 14, and the atomizing nozzle 14 sprays the absorption liquid in an atomized form, so that the absorption liquid can be fully The auger 4 is in contact with and mixed with the gas in the liquid cavity, so that the harmful waste gas is dissolved and absorbed by the atomized absorption liquid; at the same time, the rotation of the auger 4 drives the impeller 5 to rotate, and the rotation of the impeller 5 pushes the absorption liquid in the rotating drum 6 into the venturi 7, and the absorption liquid flows from the stepped cylinder to the conical cylinder in the venturi 7, and the flow diameter is compressed by the stepped channel at the stepped cylinder of the venturi 7, so that the absorption liquid impacts the harmful waste gas sprayed from the hose at a high speed at the T-tube of the venturi 7, and the harmful waste gas is split into many bubbles by the impact, so that the harmful waste gas can fully contact with the absorption liquid, and the absorption liquid can dissolve and absorb the harmful waste gas; at the same time, the rotation of the impeller 5 drives the auger 4 to rotate, and ... The rotating circular plate 16 rotates, and the rotating circular plate 16 rotates to make the first liquid stirring frame 25 rotate synchronously. The rotation of the first liquid stirring frame 25 drives the first liquid stirring rod 251 to stir the absorption liquid in the liquid cavity, so that the harmful exhaust gas bubbles rising in the absorption liquid are further broken up, so that the absorption liquid and the harmful exhaust gas are more fully contacted and absorbed; at the same time, the output shaft of the first motor 3 rotates to drive the sun gear 21 to rotate, the sun gear 21 rotates to drive the planetary gear 22 to mesh and rotate, the planetary gear 22 rotates to drive the revolving gear ring 23 to mesh and rotate, and the revolving gear ring 23 rotates to make the second liquid stirring frame 24 rotate synchronously, thereby making the second liquid stirring frame 2 The rotation drives the second liquid stirring rod 241 to stir the absorption liquid in the liquid cavity. The second liquid stirring rod 241 and the first liquid stirring rod 251 are misaligned and rotate in opposite directions. The second liquid stirring rod 241 and the first liquid stirring rod 251 stir the absorption liquid in the liquid cavity to generate mutually disturbing laminar flows, thereby causing the laminar flows to collide to form turbulent flows. After the harmful exhaust gas bubbles enter the absorption liquid in the liquid cavity, they are hit by the turbulent flow, further breaking up the harmful exhaust gas bubbles. Since the flow direction of the turbulent flow is unstable, the harmful exhaust gas bubbles are pushed by the turbulent flow, thereby prolonging the residence time of the harmful exhaust gas bubbles in the absorption liquid, further promoting the absorption liquid to dissolve and absorb the harmful exhaust gas;At the same time, the second liquid stirring frame 24 rotates to drive the driving ring 26 to rotate synchronously. The driving ring 26 rotates to make the driving rod 261 rotate around the compression sliding ring 27, so that the driving rod 261 drives the compression sliding ring 27 to slide up and down along the liquid storage ring 17 by pushing the compression sliding groove 272. When the compression sliding groove 272 slides downward, the air leakage hole 271 of the compression sliding ring 27 is contacted and closed by the liquid storage ring 17. The compression cavity composed of the mounting circular plate 2, the positioning circular plate 12, the U-shaped liquid storage cylinder 15, the driving ring 26, the compression sliding ring 27 and the liquid cavity, the gas inside is squeezed by the compression sliding groove 272, and the compression The gas pressure in the compression cavity increases, and the concentration of the gas per unit volume increases, so that the absorption liquid further fully absorbs the harmful waste gas. When the compression slide groove 272 slides upward, the air leakage hole 271 of the compression slide ring 27 connects the compression cavity with the exhaust port 101, and the gas inside the compression cavity is released by the air leakage hole 271 of the compression slide ring 27. After being absorbed by the absorption liquid, the gas in the compression cavity passes through the second air hole on the positioning circular plate 12 and reaches the first air hole of the mounting circular plate 2, and finally passes through the air leakage hole 271 of the compression slide ring 27 and is discharged to the outside through the exhaust port 101 of the housing 1. ;

[0045] At this time, the second motor 29 and the drain valve 35 are not opened, the arc slider 38 is located in the arc slide rail 37 near the oil pipe, and the pH sensor 36 detects the pH of the absorption liquid in the liquid cavity in real time. Since the harmful waste gas is an acidic gas as a whole, the absorption liquid is acidified when the harmful waste gas is absorbed by the absorption liquid, and the alkaline concentration of the absorption liquid becomes lower. When the pH sensor 36 detects that the alkaline concentration in the liquid cavity is lower than a fixed value, the pH sensor 36 sends an electrical signal to the second motor 29 to start the second motor 29, and the output shaft of the second motor 29 rotates to drive the drive gear 30 to rotate, driving the second motor 29 to rotate. The rotating gear 30 drives the gear ring segment 31 to mesh and rotate. When the gear ring segment 31 rotates, it pushes the circular arc slide 37 to rotate. When the circular arc slide 37 rotates, the waste liquid absorbed in the liquid storage barrel 33 does not immerse the hydraulic float 40, so that the hydraulic float 40 remains at the bottom of the hydraulic pipe 39 and does not move. The hydraulic oil in the hydraulic pipe 39 does not change, and the hydraulic oil in the oil pipe connected to the hydraulic pipe 39 does not change. Therefore, the hydraulic oil in the circular arc slide 37 connected to the oil pipe does not change. Since the circular arc slide 37, the circular arc slider 38, the hydraulic pipe 39 and the hydraulic float 40 are sealed and there is no air As a liquid, the volume of hydraulic oil is difficult to compress or expand, so the volume of the cavity between the arc slide 37 and the arc slider 38 remains unchanged, and the volume of the arc slider 38 is difficult to change through the hydraulic oil. At this time, it remains relatively still with the arc slide 37, so that the arc slide 37 rotates and drives the sealing ring 32 to rotate synchronously through the arc slider 38. The first liquid hole of the U-shaped liquid storage cylinder 15 and the third liquid hole of the liquid storage barrel 33 are connected with the second liquid hole of the sealing ring 32. At this time, the liquid storage barrel 33 is connected with the liquid cavity, and the absorption liquid in the liquid cavity passes through the first liquid hole of the U-shaped liquid storage cylinder 15. The liquid hole and the third liquid hole of the liquid storage barrel 33 and the second liquid hole of the sealing ring 32 form a liquid passageway that flows into the liquid storage barrel 33. At this time, the liquid level of the absorption liquid in the liquid cavity is lowered, causing the buoyancy ball 20 to fall with the liquid level. When the buoyancy ball 20 falls, the shuttle-shaped sealing block 19 is driven by the connecting rod to slide in the shuttle-shaped hole 121, so that the upper end of the shuttle-shaped hole 121 is unsealed, and then the absorption liquid in the liquid storage ring 17 flows through the flow channel of the mounting circular plate 2 into the shuttle-shaped hole 121, and flows along the connecting rod on the buoyancy ball 20 to the buoyancy ball 20, and finally flows into the absorption liquid in the liquid cavity, replenishing the absorption liquid for the liquid cavity;Furthermore, when the alkaline concentration of the absorption liquid is higher than a certain threshold value, the pH sensor 36 sends an electrical signal to the second motor 29 to start the second motor 29. The output shaft of the second motor 29 is now in the opposite direction of rotation. The output shaft of the second motor 29 rotates to drive the driving gear 30 to rotate. The driving gear 30 rotates to drive the gear ring segment 31 to rotate synchronously. The gear ring segment 31 rotates to drive the circular arc slide 37 to rotate synchronously. At this time, the circular arc slide 37, the circular arc slider 38, the hydraulic pipe 39 and the hydraulic float 40 are sealed and there is no gas. Since the hydraulic oil is difficult to compress or expand, the circular arc slide The block 38 is kept relatively still in the circular arc slide 37 by the hydraulic oil. The circular arc slide 37 rotates and drives the sealing ring 32 to rotate through the circular arc slider 38, so that the first liquid hole of the U-shaped liquid storage cylinder 15 and the third liquid hole of the liquid storage barrel 33 are staggered and sealed with the second liquid hole of the sealing ring 32; at the same time, the liquid level of the absorption liquid in the liquid cavity continues to rise, driving the buoyancy ball 20 to move upward synchronously. The buoyancy ball 20 moves through the connecting rod to drive the shuttle-shaped sealing block 19 to slide upward along the shuttle-shaped hole 121, so that the upper end of the shuttle-shaped hole 121 is sealed by the shuttle-shaped sealing block 19, and the absorption liquid in the liquid cavity is replenished. ;

[0046] Furthermore, when the liquid level of the absorbed waste liquid in the liquid storage barrel 33 submerges the hydraulic float 40, the hydraulic float 40 slides upward in the hydraulic pipe 39 due to the buoyancy, so that the hydraulic oil in the hydraulic pipe 39 enters the circular arc slide rail 37 through the oil pipe. The volume of the hydraulic oil in the circular arc slide rail 37 increases, so that the hydraulic oil squeezes the circular arc slide block 38 to slide along the circular arc slide rail 37. The sliding of the circular arc slide block 38 drives the sealing ring 32 to rotate synchronously. At this time, regardless of whether the second motor 29 is started or not, the second liquid hole of the sealing ring 32 and the first liquid hole of the U-shaped liquid storage cylinder 15 and the third liquid hole of the liquid storage barrel 33 are always in a staggered sealed state, ensuring that the absorbed liquid in the liquid cavity will not be contaminated by the absorbed waste liquid in the liquid storage barrel 33.

[0047] At this time, the drain valve 35 is started to allow the absorbed waste liquid in the liquid storage barrel 33 to flow through the drain pipe 34 and flow to the outside through the drain valve 35 to wait for recycling and processing; when the liquid level of the absorbed waste liquid in the liquid storage barrel 33 drops, the hydraulic float 40 is no longer affected by the buoyancy of the absorbed waste liquid in the liquid storage barrel 33, so that the hydraulic float 40 slowly descends along the hydraulic pipe 39. At the same time, the volume in the hydraulic pipe 39 increases. Since the volume of the hydraulic oil is difficult to change, the hydraulic pipe 39 absorbs hydraulic oil from the oil pipe, and then the oil pipe absorbs the hydraulic oil in the arc slide rail 37. Since the volume of the hydraulic oil is difficult to expand, the volume of the cavity in the arc slide rail 37 and the arc slider 38 becomes smaller, so that the arc slider 38 slides in the arc slide rail 37, and then the arc slider 38 drives the sealing ring 32 to rotate, so that the first liquid through hole of the U-shaped liquid storage barrel 15 and the third liquid through hole of the liquid storage barrel 33 are restored to a state where they can be connected.

Accordingly, the scope of the present invention should be limited only by the appended claims.
