DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-10 As shown, a vertical PP acid-base waste gas washing tower comprises a tower body 1, an air inlet 11 arranged on the tower body 1, and a spray unit in the tower body 1, and also comprises a splash block 2 fixedly installed in the tower body 1 and located between one side of the air inlet 11 and the spray unit, an impeller block 3 driven by air blowing from the air inlet 11 is rotatably arranged in an air duct opening 21 opened on the splash block 2, and a through groove 22 arranged in a circular array is opened on the top of the splash block 2;

[0036] Also included is a splash assembly for splashing liquid, the splash assembly comprising:

[0037] The grid plate 4 is disposed in the through slot 22 and has a plurality of air inlets 42 formed thereon. The grid plate 4 has inclined portions 43 symmetrically disposed on both sides of the air inlets 42.

[0038] The main push rod 7 is slidably disposed in the splash block 2, and the abutment portion 72 disposed at the first end of the main push rod 7 is engaged with the protrusion 32 on the impeller block 3, and the elastic plate 73 disposed on the main push rod 7 scrapes the tooth opening 44 disposed on the grid plate 4 to make the grid plate 4 vibrate;

[0039] The main spring 71 releases the stored force to strike the guide plate 31 on the impeller block 3 when the main push rod 7 is separated from the protrusion 32 .

[0040] Specifically, the spray unit includes a spray rack 13 fixedly installed in the tower body 1, a guide channel 14 arranged on the spray rack 13 is fixedly connected to the water inlet pipe 12 arranged on the outer wall of the tower body 1, and a ring channel 15 arranged on the spray rack 13 is connected to the guide channel 14. A plurality of branch channels 17 connected to the ring channel 15 and the guide channel 14 are arranged on the spray rack 13, and an atomizing nozzle 18 is fixedly installed at the bottom port of each branch channel 17. By pumping the washing liquid into the guide channel 14 along the water inlet pipe 12, the washing liquid in the guide channel 14 flows to the ring channel 15, and the washing liquid in the ring channel 15 and the guide channel 14 flows to the plurality of branch channels 17 respectively, and then mist droplets are sprayed along the atomizing nozzle 18.

[0041] Furthermore, the splash block 2 is located below the spray rack 13, and the acid and alkali waste gas blown into the tower body 1 along the air inlet 11 is located below the splash block 2. The outer wall of the impeller block 3 is provided with a plurality of turbine blades 33 arranged in a circular array, and the impeller block 3 is rotatably arranged on a support plate 23 fixedly installed in the air duct opening 21. The gas blown into the tower body 1 along the air inlet 11 begins to diffuse toward the top of the tower body 1. At this time, the gas flows along the air duct opening 21 and the through groove 22 respectively. Due to the flow of the gas on the turbine blades 33, the impeller block 3 is driven to rotate on the support plate 23. At the same time, part of the gas flows into the through groove 22 along the air inlet 42 on the grid plate 4.

[0042] Furthermore, the elastic plate 73 is fixedly mounted on the main push rod 7. After the atomizing nozzle 18 sprays out the mist droplets, the mist droplets fall down to neutralize the acid-base waste gas flowing out along the through groove 22 and the air duct opening 21. At the same time, part of the mist droplets will condense into droplets when contacting the guide plate 31 and the grid plate 4. Part of the droplets condensed on the grid plate 4 will flow along the air filling port 42 to the bottom of the tower body 1, and part of the droplets condensed on the guide plate 31 will flow along the inner wall of the air duct opening 21 to the bottom of the tower body 1.

[0043] Furthermore, the first end of the main spring 71 is fixedly mounted on the second end of the main push rod 7, the second end of the main spring 71 is fixedly mounted on the splash block 2, the inclined portions 43 face the air inlet 42 respectively, and the protrusions 32 are fixedly mounted on the side wall of the impeller block 3 and arranged in a circular array. Therefore, when the acid-base waste gas flows on the turbine blades 33 to drive the impeller block 3 to rotate on the support plate 23, the protrusions 32 on the impeller block 3 approach and squeeze the abutment 72 to make the main push rod 7 slide, and the main push rod 7 slides to squeeze the main spring 71 to deform and store force, and then when the protrusions 32 are separated from the abutment 72, the main spring 71 releases the stored force to make the main push rod 7 slide again. Therefore, during the reciprocating sliding of the main push rod 7, the elastic plate 73 on the main push rod 7 is used to scrape the tooth opening 44 set on the grid plate 4 to make the grid plate 4 vibrate. When the grid plate 4 vibrates, the liquid on the inclined surface 43 is splashed due to vibration and splashes to the air filling port 42, and the acid-base waste gas flowing with the air filling port 42 is neutralized again with the unreacted washing liquid in the splashing liquid, thereby improving the utilization rate of the washing liquid. At the same time, when the main push rod 7 is separated from the protrusion 32 and the main spring 71 releases the stored force to slide the main push rod 7, the abutment portion 72 on the main push rod 7 is used to knock the guide plate 31 on the impeller block 3. At this time, the condensed liquid on the guide plate 31 is splashed, and then the acid-base waste gas flowing between the inner wall of the air duct opening 21 and the outer wall of the impeller block 3 and the unreacted washing liquid in the splashing liquid are neutralized again to improve the utilization rate of the washing liquid. Then the neutralized gas flows to the top of the tower body 1 along the air passage 16 opened on the spray rack 13.

[0044] Compared with allowing the condensed liquid to directly slide down and accumulate to be discharged from the tower body 1, the washing liquid in the condensed liquid is sputtered and reacts with the acid-base waste gas again, thereby improving the utilization rate of the washing liquid.

[0045] In the above technical scheme, the acid-base waste gas blown into the tower body 1 is utilized to drive the impeller block 3 to rotate, and then the main push rod 7 is moved during the rotation of the impeller block 3, and then the elastic plate 73 on the main push rod 7 is used to scrape the tooth mouth 44 set on the grid plate 4 to make the grid plate 4 vibrate, and the liquid containing the washing liquid is splashed under the vibration of the grid plate 4, and then the splashed liquid is neutralized with the acid-base waste gas again, so as to improve the utilization rate of the washing liquid, and at the same time, when the main spring 71 pushes the main push rod 7 to reset, the main push rod 7 is used to knock the guide plate 31, so that the guide plate 31 vibrates and the liquid on it is splashed, and then the washing liquid in the splashed liquid and the acid-base waste gas flowing in the air duct opening 21 are neutralized again, so as to improve the utilization rate of the washing liquid again.

[0046] As an embodiment further provided by the present invention, the elastic plates 73 are respectively hingedly arranged on the vertical rods 75 symmetrically arranged on the main push rod 7, and when the abutment portion 72 and the protrusion 32 are engaged in a blocking manner, the bottom end of the elastic plate 73 is attached to the vertical rod 75, and when the main push rod 7 hits the guide plate 31, the elastic plate 73 is pushed over and rotated by the tooth mouth 44.

[0047] Specifically, Figure 8 and Fig.10 As shown, a limit torsion spring 74 is sleeved on the hinge axis of the elastic plate 73 hinged on the vertical rod 75, and the two ends of the limit torsion spring 74 are respectively fixedly installed on the vertical rod 75 and the elastic plate 73, and the limit torsion spring 74 drives the bottom end of the elastic plate 73 to fit on the vertical rod 75.

[0048] Then, when the acid-base waste gas is blown into the tower body 1 along the air inlet 11 and flows along the air duct opening 21 and the through groove 22 respectively, the flow of the acid-base waste gas on the turbine blades 33 in the air duct opening 21 drives the impeller block 3 to rotate on the support plate 23. At this time, the protrusion 32 on the impeller block 3 approaches and squeezes the abutment 72 to make the main push rod 7 slide. At this time, the main push rod 7 slides to squeeze the main spring 71 to deform and store force. At the same time, due to the sliding of the main push rod 7, the elastic plate 73 on the main push rod 7 scrapes against the tooth opening 44 set on the grid plate 4 to make the grid plate 4 vibrate. The elastic plate 73 is supported by the vertical rod 75, so that the elastic plate 73 remains in a vertical state when the elastic plate 73 scrapes against the tooth opening 44. Then, when the protrusion 32 is separated from the abutment 72, the main spring 71 releases the stored force to make the main push rod 7 slide again. At this time, the elastic plate 73 is pushed by the tooth opening 44 to turn over, and at the same time, the abutment portion 72 on the main push rod 7 strikes the guide plate 31 on the impeller block 3 .

[0049] Therefore, the reciprocating movement of the main push rod 7 is used to drive the grid plate 4 and the guide plate 31 to vibrate, so that the condensed droplets containing the washing liquid are splashed due to the vibration of the grid plate 4 and the guide plate 31 and neutralized with the acid-base waste gas.

[0050] When the main push rod 7 slides to make the abutment 72 knock the impeller block 3, the elastic plate 73 is pushed by the tooth opening 44 to flip, thereby reducing the resistance of the main push rod 7 when sliding, so that when the main spring 71 releases the stored force to push the main push rod 7 to slide, the abutment 72 can knock the guide plate 31 more strongly to vibrate. Thus, the effect of liquid splashing on the guide plate 31 is enhanced.

[0051] Another embodiment provided by the present invention includes a first knocking plate 5 symmetrically hingedly arranged in the through groove 22, and a first torsion spring member 51 is sleeved on a second hinge shaft 52 arranged on the first knocking plate 5 to drive the bottom end of the first knocking plate 5 to fit onto the grid plate 4.

[0052] Specifically, the two ends of the first torsion spring member 51 are respectively fixedly mounted on the first knocking plate 5 and the inner wall of one side of the through groove 22, and the first torsion spring member 51 drives the bottom end of the first knocking plate 5 to fit on the grid plate 4. Therefore, in the process of the elastic plate 73 on which the main push rod 7 slides and scrapes on the tooth mouth 44 to make the grid plate 4 vibrate, since the bottom end of the first knocking plate 5 fits on the grid plate 4, the first knocking plate 5 also vibrates accordingly, and then the droplets containing detergent condensed on the first knocking plate 5 are splashed due to the vibration of the first knocking plate 5, and then neutralized with the acid-base waste gas sprayed from the air filling port 42, thereby improving the utilization rate of the detergent.

[0053] Furthermore, in the process of driving the bottom end of the first knocking plate 5 to flip up and away from the grid plate 4, the first torsion spring member 51 deforms and accumulates force, and then when the first knocking plate 5 is released, the first torsion spring member 51 releases the accumulated force to drive the bottom end of the first knocking plate 5 to knock the grid plate 4 to vibrate, and when the grid plate 4 vibrates, the liquid on the inclined portion 43 is splashed due to vibration and splashes to the air filling port 42, and the acid and alkali waste gas flowing through the air filling port 42 is used to neutralize the unreacted detergent in the splashing liquid again. And when the first knocking plate 5 hits the grid plate 4, the first knocking plate 5 itself will also vibrate, thereby causing the condensed droplets on the first knocking plate 5 to splash again, so as to neutralize the acid and alkali waste gas flowing through the air filling port 42 again.

[0054] Furthermore, the first knocking plate 5 can be driven to flip by a motor cooperating with a cam to push the first knocking plate 5 to flip and release; it can also be an electric push rod cooperating with a connecting rod; or it can be any method known to those skilled in the art to drive the first knocking plate 5 to flip and release.

[0055] As another embodiment provided by the present invention, a second knocking plate 6 is symmetrically hingedly arranged in the through groove 22, and a second torsion spring member 61 is sleeved on the first hinge shaft 65 arranged on the second knocking plate 6 to drive the bottom end of the second knocking plate 6 to fit on the grid plate 4.

[0056] Specifically, the two ends of the second torsion spring member 61 are respectively fixedly mounted on the second knocking plate 6 and the inner wall on one side of the through groove 22, and the second torsion spring member 61 drives the bottom end of the second knocking plate 6 to fit on the grid plate 4. Therefore, in the process of the elastic plate 73 on which the main push rod 7 slides and scrapes on the tooth mouth 44 to make the grid plate 4 vibrate, since the bottom end of the second knocking plate 6 fits on the grid plate 4, the second knocking plate 6 also vibrates accordingly, and then the droplets containing detergent condensed on the second knocking plate 6 are splashed due to the vibration of the second knocking plate 6, and then neutralized with the acid-base waste gas sprayed from the air filling port 42 to improve the utilization rate of the detergent.

[0057] Furthermore, in the process of driving the bottom end of the second knocking plate 6 to flip up and away from the grid plate 4, the second torsion spring member 61 deforms and accumulates force, and then when the second knocking plate 6 is released, the second torsion spring member 61 releases the accumulated force to drive the bottom end of the second knocking plate 6 to knock the grid plate 4 to vibrate, and when the grid plate 4 vibrates, the liquid located on the inclined portion 43 is sputtered and splashed to the air filling port 42 due to the vibration, and the acid-base waste gas flowing with the air filling port 42 is neutralized again with the unreacted detergent in the splashing liquid. And when the second knocking plate 6 hits the grid plate 4, the second knocking plate 6 itself will also vibrate, thereby causing the condensed droplets on the second knocking plate 6 to splash again, so as to facilitate the neutralization again with the acid-base waste gas flowing in the air filling port 42.

[0058] Furthermore, the second knocking plate 6 can be driven to flip by a motor cooperating with a cam to push the second knocking plate 6 to flip and release; it can also be driven by an electric push rod cooperating with a connecting rod; or it can be driven by any method known to those skilled in the art to flip and release the second knocking plate 6.

[0059] As another embodiment provided by the present invention, a receiving box 63 is fixedly installed on the top of the second knocking plate 6, and an inner wall of the receiving box 63 is provided with a drainage port 64 for leaking water when the second knocking plate 6 is turned over and tilted.

[0060] Specifically, by utilizing the receiving box 63 fixedly installed at the top of the second knocking plate 6, when the second torsion spring member 61 drives the bottom end of the second knocking plate 6 to fit on the grid plate 4, the liquid falling from the spray rack 13 can be accumulated in the receiving box 63, and then when the bottom end of the second knocking plate 6 is turned up to tilt, the second torsion spring member 61 is deformed and accumulates force, and at this time, the liquid accumulated in the receiving box 63 is discharged from the receiving box 63 along the drain port 64, and the liquid discharged from the receiving box 63 is discharged from the receiving box 63 by impacting the grid plate 4 under the action of gravity. The grid plate 4 splashes, and the splashed liquid can be neutralized again with the acid-base waste gas flowing through the air inlet 42. Secondly, when the bottom end of the second knocking plate 6 stops turning up and is released, the second torsion spring member 61 releases the stored force to drive the bottom end of the second knocking plate 6 to knock the grid plate 4 to vibrate. When the grid plate 4 vibrates, the liquid on the inclined surface 43 is splashed and splashed to the air inlet 42 due to the vibration, and the acid-base waste gas flowing through the air inlet 42 is neutralized again with the unreacted detergent in the splashed liquid. And when the second knocking plate 6 hits the grid plate 4, the second knocking plate 6 itself will also vibrate, thereby causing the condensed droplets on the second knocking plate 6 to splash again, so as to neutralize again with the acid-base waste gas flowing through the air inlet 42.

[0061] As the optimal embodiment provided by the present invention, the top end of the second knocking plate 6 and the top end of the first knocking plate 5 approach and collide with each other, and when the second knocking plate 6 and the first knocking plate 5 rotate, the second torsion spring 61 and the first torsion spring 51 are deformed and force is stored respectively.

[0062] Specifically, by turning up the bottom end of the second knocking plate 6 and the bottom end of the first knocking plate 5, the top end of the second knocking plate 6 and the top end of the first knocking plate 5 are brought close to each other and collided, and then the second knocking plate 6 and the first knocking plate 5 respectively vibrate. Under the vibration of the second knocking plate 6 and the first knocking plate 5, the unreacted washing liquid condensed on the second knocking plate 6 and the first knocking plate 5 splashes and is respectively neutralized with the acid and alkali waste gas flowing from the air inlet 42. At the same time, when the second knocking plate 6 and the first knocking plate 5 are turned over, the second torsion spring member 61 and the first torsion spring member 51 are deformed and stored.

[0063] Furthermore, when the bottom end of the second knocking plate 6 and the bottom end of the first knocking plate 5 are stopped from turning up and released, the second torsion spring member 61 and the first torsion spring member 51 release their stored forces respectively, so that the bottom ends of the second knocking plate 6 and the first knocking plate 5 respectively hit the grid plate 4 to make the grid plate 4 and the second knocking plate 6 and the first knocking plate 5 vibrate respectively, so that the unreacted washing liquid condensed on the grid plate 4 and the second knocking plate 6 and the first knocking plate 5 are splashed again and neutralized again with the acid-base waste gas flowing from the air filling port 42, so as to make full use of the condensed droplets of unreacted washing liquid to avoid them flowing directly to the bottom of the tower body 1, causing the problem of low utilization rate of the washing liquid.

[0064] As another embodiment provided by the present invention, the first hinge shaft 65 and the outer wall of the second hinge shaft 52 are respectively fixedly mounted with first gears 53 that mesh with each other, and the outer walls of the two second hinge shafts 52 are respectively fixedly mounted with second gears 54 that mesh with each other.

[0065] Specifically, the first gear 53 between the first hinge shaft 65 and the second hinge shaft 52 on the adjacent second knocking plate 6 and the first knocking plate 5 is meshed with each other, so that when a single second knocking plate 6 or first knocking plate 5 rotates, the corresponding second knocking plate 6 or first knocking plate 5 is driven to flip synchronously, and by making the second gears 54 on the outer walls of the second hinge shafts 52 on the two first knocking plates 5 mesh with each other, the other first knocking plate 5 is driven to flip when a single first knocking plate 5 flips. Therefore, when driving any second knocking plate 6 or first knocking plate 5 to flip, the meshing between the two second gears 54 and the meshing between the two first gears 53 are coordinated to drive the two second knocking plates 6 and the two first knocking plates 5 in the through groove 22 to flip synchronously respectively, and because the first gear 53 between the first hinge shaft 65 and the second hinge shaft 52 are meshed with each other, the top end of the second knocking plate 6 and the top end of the first knocking plate 5 approach and collide with each other during the flipping process of the second knocking plate 6 and the first knocking plate 5.

[0066] The driving method for flipping and releasing any second knocking plate 6 or first knocking plate 5 in the through-slot 22 may be a motor cooperating with a cam to push any second knocking plate 6 or first knocking plate 5 to flip and release; or an electric push rod cooperating with a connecting rod; or any method known to those skilled in the art to drive any second knocking plate 6 or first knocking plate 5 to flip and release.

[0067] As another embodiment provided by the present invention, a cover 62 covering the drain outlet 64 is fixedly mounted on the second knocking plate 6, and when the top end of the first knocking plate 5 is attached to the cover 62, the bottom ends of the two first knocking plates 5 are respectively brought together to cover the grid plate 4.

[0068] Specifically, an exhaust passage connected to the drain port 64 is provided between the cover 62 and the outer wall of the second knocking plate 6 .

[0069] When any one of the second knocking plates 6 or the first knocking plates 5 flips over, the meshing between the two second gears 54 and the meshing between the two first gears 53 drive the two second knocking plates 6 and the two first knocking plates 5 in the through groove 22 to flip over synchronously respectively, and the first gear 53 between the first hinge shaft 65 and the second hinge shaft 52 meshes with each other to make the top end of the second knocking plate 6 and the top end of the first knocking plate 5 approach and collide with each other.

[0070] Further, such as Figure 7 and Figure 8 As shown, when the top of the second knocking plate 6 and the top of the first knocking plate 5 approach each other and collide, the first knocking plate 5 is now attached to the cover 62 on the second knocking plate 6, and the bottom ends of the first knocking plates 5 are respectively flipped up to be away from the grid plate 4, and the bottom ends of the two first knocking plates 5 are respectively turned up to approach each other, thereby partially shielding the flow port 41 opened on the grid plate 4, and under a certain shielding of the two first knocking plates 5, part of the acid-base waste gas flowing from the flow port 41 flows along the first knocking plate 5 to the exhaust duct, and because the first knocking plate 5 is attached to the cover 62 to close the gap between the first knocking plate 5 and the cover 62, the exhaust gas flows along the air inlet 42 and the flow port 41 on the grid plate 4. Most of the flowing acid and alkali waste gases will flow into the exhaust duct respectively, and the top of the second knocking plate 6 is flipped and tilted so that the liquid accumulated in the receiving box 63 is discharged into the exhaust duct along the drain port 64, and the liquid flowing in the exhaust duct and the flowing gas in the exhaust duct collide with each other so that the liquid is broken up by the impact, so that the unreacted washing liquid in the broken up liquid is neutralized with the acid and alkali waste gases again. The first knocking plate 5 is flipped to block the gap between the first knocking plate 5 and the cover 62 and the gap between the two first knocking plates 5, so that most of the blast through the groove 22 can act on the exhaust duct, thereby enhancing the flow rate of the acid and alkali waste gases in the exhaust duct, thereby more strongly breaking up the liquid discharged into the exhaust duct.

[0071] As another embodiment further provided by the present invention, it also includes a gear rod member 8 sliding on the splash block 2 and meshing with one of the second gears 54, the first end of the gear rod member 8 is located on the moving path of the protrusion 32, and the gear rod member 8 and the protrusion 32 are matched to slide.

[0072] Specifically, Figure 5 and Fig. 9 As shown, the gear rod member 8 slides in the splash block 2 and meshes with one of the second gears 54, and the first end of the gear rod member 8 is located in the moving path of the protrusion 32. Therefore, when the protrusion 32 rotates with the impeller block 3, the protrusion 32 squeezes the curved surface portion 81 set at the first end of the gear rod member 8, so that the gear rod member 8 and the second gear 54 are meshed with each other to rotate the second hinge shaft 52. When the second hinge shaft 52 rotates, the two second knocking plates 6 and the two first knocking plates 5 in the through groove 22 are driven to flip synchronously respectively by coordinating the meshing between the two second gears 54 and the meshing between the two first gears 53. In addition, because the first gear 53 between the first hinge shaft 65 and the second hinge shaft 52 is meshed with each other, the top of the second knocking plate 6 and the top of the first knocking plate 5 are brought close to and collided with each other during the flipping process of the second knocking plate 6 and the first knocking plate 5.

[0073] Furthermore, when the first end of the gear rod 8 is provided with an arc surface 82 connected to one side of the curved surface 81, when the end of the protrusion 32 moves along the curved surface 81 to the arc surface 82, at this time, the top side of the two first knocking plates 5 is respectively attached to the cover 62 on the second knocking plate 6, and the bottom ends of the first knocking plates 5 are respectively turned up to move away from the grid plate 4, and the bottom ends of the two first knocking plates 5 are respectively turned up to get close to each other, thereby partially covering the flow port 41 opened on the grid plate 4. Under a certain shielding of the two first knocking plates 5, part of the acid-base waste gas flowing from the flow port 41 flows along the first knocking plates 5 to the exhaust duct. And because the first knocking plate 5 is attached to the cover 62 to close the gap between the first knocking plate 5 and the cover 62, the top end of the second knocking plate 6 is flipped and tilted so that the liquid accumulated in the receiving box 63 is discharged into the exhaust duct along the drain port 64, and the liquid flowing in the exhaust duct and the flowing gas in the exhaust duct collide with each other so that the liquid is broken up by the impact, so that the unreacted washing liquid in the broken up liquid is neutralized with the acid and alkali waste gas again, and when the end of the protrusion 32 slides along the arc surface 82, the top side of the first knocking plate 5 remains in a state of being attached to the cover 62, so that the blast can continue to flow along the exhaust duct for a certain period of time.

[0074] As a further optimal embodiment of the present invention, when the gear rod member 8 is disengaged from the protrusion 32 , the second torsion spring member 61 and the first torsion spring member 51 release their stored forces respectively to enable the gear rod member 8 to strike the guide plate 31 .

[0075] Specifically, the second torsion spring 61 and the first torsion spring 51 are used to drive the bottom ends of the second knocking plate 6 and the first knocking plate 5 to fit on the grid plate 4 respectively, and then when the acid and alkali waste gas is blown into the tower body 1 along the air inlet 11, the gas blown into the tower body 1 along the air inlet 11 begins to diffuse toward the top of the tower body 1, and at this time, the gas flows along the air duct opening 21 and the through groove 22 respectively, and the flow of the gas on the turbine blade 33 drives the impeller block 3 to rotate on the support plate 23. At the same time, part of the gas flows into the through groove 22 along the air inlet 42 on the grid plate 4.

[0076] When the impeller block 3 rotates, the protrusion 32 on the impeller block 3 approaches and squeezes the abutment portion 72 to make the main push rod 7 slide. At this time, the main push rod 7 slides to squeeze the main spring 71 to deform and store force. At the same time, due to the sliding of the main push rod 7, the elastic plate 73 on the main push rod 7 scrapes against the tooth opening 44 set on the grid plate 4 to make the grid plate 4 vibrate, and the elastic plate 73 is supported by the vertical rod 75, so that the elastic plate 73 remains in a vertical state when the elastic plate 73 scrapes against the tooth opening 44. When the grid plate 4 vibrates, the liquid on the inclined portion 43 is splashed due to the vibration and splashes to the air filling port 42, and the acid and alkali waste gas flowing along with the air filling port 42 is neutralized again with the unreacted washing liquid in the splashing liquid, thereby improving the utilization rate of the washing liquid. Secondly, since the bottom ends of the second knocking plate 6 and the first knocking plate 5 are respectively attached to the grid plate 4, they will vibrate along with the grid plate 4. When the second knocking plate 6 and the first knocking plate 5 vibrate, the droplets containing detergent condensed on the second knocking plate 6 and the first knocking plate 5 will splash due to the vibration, and then neutralize with the acid and alkali waste gas sprayed from the air filling port 42, so as to further improve the utilization rate of the detergent.

[0077] Furthermore, when the abutment 72 on the main push rod 7 disengages from the protrusion 32, the main spring 71 releases the stored force to slide the main push rod 7. At this time, the elastic plate 73 is pushed by the tooth mouth 44 to flip over. At the same time, the abutment 72 on the main push rod 7 hits the guide plate 31 on the impeller block 3. At this time, the condensed liquid on the guide plate 31 splashes, and then the acid-base waste gas flowing between the inner wall of the air duct opening 21 and the outer wall of the impeller block 3 and the unreacted washing liquid in the splashed liquid are neutralized again.

[0078] Furthermore, as the impeller block 3 continues to rotate, the protrusion 32 disengages from the abutment portion 72 and begins to squeeze the curved surface portion 81 provided at the first end of the gear rod member 8, thereby causing the gear rod member 8 to slide and mesh with the second gear 54 to rotate the second hinge shaft 52. When the second hinge shaft 52 rotates, the meshing between the two second gears 54 and the meshing between the two first gears 53 are coordinated to drive the two second knocking plates 6 and the two first knocking plates 5 in the through groove 22 to flip synchronously respectively. Moreover, since the first hinge shaft 65 and the first hinge shaft 52 are meshed with each other, the top end of the second knocking plate 6 and the top end of the first knocking plate 5 are brought close to and collide with each other during the flipping process of the second knocking plate 6 and the first knocking plate 5.

[0079] When the top of the second knocking plate 6 and the top of the first knocking plate 5 approach and collide with each other, the second knocking plate 6 and the first knocking plate 5 vibrate respectively, so that the unreacted washing liquid condensed thereon splashes and neutralizes the acid and alkali waste gas flowing from the air inlet 42. At the same time, when the second knocking plate 6 and the first knocking plate 5 are turned over, the second torsion spring member 61 and the first torsion spring member 51 are deformed and stored respectively.

[0080] Furthermore, when the end of the protrusion 32 moves along the curved surface 81 to the arc surface 82, at this time, the top side of the two first knocking plates 5 is respectively attached to the cover 62 on the second knocking plate 6, and the bottom ends of the first knocking plates 5 are respectively turned up to be away from the grid plate 4, and the bottom ends of the two first knocking plates 5 are respectively turned up to get closer to each other, thereby partially shielding the flow port 41 opened on the grid plate 4. Under the certain shielding of the two first knocking plates 5, part of the acid-base waste gas flowing from the flow port 41 flows along the first knocking plate 5 to the exhaust duct, and because the first knocking plate 5 is attached to the cover 6 2 to close the gap between the first knocking plate 5 and the cover 62, and with the flipping and tilting of the top end of the second knocking plate 6, the liquid accumulated in the receiving box 63 is discharged into the exhaust duct along the drain port 64, and the liquid flowing in the exhaust duct and the flowing gas in the exhaust duct collide with each other to break up the liquid by impact, so that the unreacted washing liquid in the broken up liquid is neutralized with the acid-base waste gas again, and when the end of the protrusion 32 slides along the arc surface 82, the top side of the first knocking plate 5 is kept in contact with the cover 62, so that the blast can continue to flow along the exhaust duct for a certain period of time.

[0081] Furthermore, when the end of the protrusion 32 disengages from the arc surface 82, the second torsion spring member 61 and the first torsion spring member 51 release their stored forces respectively, thereby causing the first hinge shaft 65 and the second hinge shaft 52 to reset and flip. At this time, the second gear 54 is again meshed with the gear rod member 8 to allow the gear rod member 8 to slide to hit the guide plate 31. At the same time, the first hinge shaft 65 and the second hinge shaft 52 are reset and flipped to drive the second knocking plate 6 and the first knocking plate 5 to reset and flip, and the bottom of the second knocking plate 6 and the first knocking plate 5 respectively hit the grid plate 4, so that the grid plate 4 vibrates again to splash the liquid on the grid plate 4, thereby neutralizing the splashed acid and alkali waste gas containing unreacted washing liquid and flowing from the air inlet 42 again.

[0082] Therefore, by utilizing multiple vibrations of the grid plate 4 and the guide plate 31, the second knocking plate 6 and the first knocking plate 5, the unreacted washing liquid in the condensed liquid is splashed and neutralized with the acid-base waste gas again, thereby improving the washing liquid to be more fully neutralized with the acid-base waste gas during a single spraying process, thereby improving the utilization rate of the washing liquid.

[0083] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
