DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] Embodiment 1:

[0040] Reference Figure 1-Figure 8 An industrial waste gas treatment device comprises a spray tower 1 provided with a smoke inlet 2 and a smoke exhaust pipe 3, and also comprises a vertical pipe 4 rotatably installed in the spray tower 1 through a bracket, wherein an outer wall of the spray tower 1 is fixedly connected with a liquid inlet pipe 13 connected with the upper end of the vertical pipe 4, and the liquid inlet pipe 13 is used to transport water to the vertical pipe 4, and a plurality of circumferentially distributed nozzles 5 are fixedly installed at the lower end of the vertical pipe 4, and the number of the nozzles 5 is 3-12, and the preferred number of the present application is 3, and nozzles 6 for spraying are fixedly installed at the lower ends of the plurality of nozzles 5, and a driving part for driving the vertical pipe 4 to rotate is provided in the spray tower 1.

[0041] When in use, the smoke will be introduced into the spray tower 1 from the smoke inlet 2, and the treated smoke will be discharged from the smoke exhaust pipe 3. While the smoke passes through the spray tower 1, the spray liquid is transported to the liquid inlet pipe 13, and the liquid will enter the vertical pipe 4. Finally, it will be sprayed into the spray tower 1 from the nozzle 6 at the lower end of the nozzle 5 to carry out dust reduction treatment on the smoke. When the smoke passes through the smoke exhaust pipe 3, the driving unit will drive the vertical pipe 4 to rotate, and the vertical pipe 4 will drive the nozzle 5 and the nozzle 6 at the lower end to revolve around their axis, thereby significantly increasing the spraying area of ​​the nozzle 6, thereby reducing the smoke directly passing through the spraying area, and improving the treatment effect of industrial waste gas.

[0042] The lower end side wall of the above-mentioned spray tower 1 is fixedly connected with a sewage pipe 33, and a valve is installed on the sewage pipe 33. The smoke inlet 2 is located above the sewage pipe 33, so the sewage generated by spraying will be retained at the inner bottom of the spray tower 1. When there is a lot of sewage, the valve on the sewage pipe 33 can be opened to allow the spray tower 1 to discharge excess sewage through the sewage pipe 33.

[0043] Embodiment 2:

[0044] Reference Figure 3-Figure 4 , which is basically the same as the first embodiment, and further discloses a specific implementation scheme of the driving unit.

[0045] The above-mentioned driving part includes a device box 7 fixedly connected to the side wall of the smoke exhaust pipe 3, and a fan blade 9 extending into the smoke exhaust pipe 3 is rotatably installed in the device box 7 through a rotating shaft 8, wherein a transmission shaft 10 is rotatably connected to the spray tower 1, and the upper end of the transmission shaft 10 is connected to the rotating shaft 8 through two mutually meshing transmission gears 11, and the transmission shaft 10 is connected to the vertical pipe 4 through a chain drive 12.

[0046] Specifically, when the smoke passes through the smoke exhaust pipe 3, the flowing smoke will drive the fan blades 9 to rotate, and the fan blades 9 will drive the rotating shaft 8 to rotate. The rotating shaft 8 will drive the transmission shaft 10 to rotate through two mutually meshing transmission gears 11. The transmission shaft 10 will drive the vertical pipe 4 to rotate through the chain drive 12. The vertical pipe 4 will drive the nozzle 5 and the nozzle 6 at the lower end to revolve around its axis, thereby significantly increasing the spraying area of ​​the nozzle 6, thereby reducing the smoke directly passing through the spraying area, and improving the treatment effect of industrial waste gas.

[0047] Embodiment three:

[0048] Reference Figure 3-Figure 8 , which is basically the same as Example 2, and further, a specific implementation plan for improving the effect of industrial waste gas treatment is specifically added.

[0049] A cylinder 14 fixedly connected to the vertical pipe 4 is rotatably installed on the inner top of the above-mentioned spray tower 1, and a plurality of mounting grooves 15 distributed circumferentially are provided on the upper end of the cylinder 14. Adsorption plates 16 are installed in the plurality of mounting grooves 15, and the surface of the adsorption plates 16 is an uneven non-flat surface. A transverse pipe 17 extending to the interior is laterally inserted into the outer wall of the spray tower 1, and a nozzle 18 is fixedly installed at the lower end of the transverse pipe 17. A wind shield 31 is fixedly connected to the inner wall of the lower end of the spray tower 1, and the nozzle 18 faces the inside of the wind shield 31. The bottom of the wind shield 31 is fixedly connected to a reflux pipe 32 extending to the bottom of the spray tower 1.

[0050] During the treatment of industrial waste gas, liquid enters the horizontal pipe 17, and the horizontal pipe 17 sprays the liquid onto the adsorption plate 16 through the nozzle 18. The rotating vertical pipe 4 drives the cylinder 14 to rotate, and the cylinder 14 drives multiple adsorption plates 16 to revolve around the axis of the vertical pipe 4, so that each adsorption plate 16 can be wetted by the liquid. The wetted adsorption plate 16 can further adsorb the particles in the waste gas to improve the treatment effect of the industrial waste gas. The adsorption plate 16 revolving around the axis of the vertical pipe 4 can significantly improve the efficiency of adsorbing floating dust, so that the efficiency of industrial waste gas treatment is higher.

[0051] When the nozzle 18 sprays liquid, it will also flush the adsorption plate 16. During the flushing, the wind shield 31 will block the lower end of the adsorption plate 16 to prevent the upward airflow from affecting the flushing effect. The sewage generated by the flushing will flow along the adsorption plate 16 into the wind shield 31, and will eventually flow into the bottom of the spray tower 1 through the reflux pipe 32, thereby realizing the automatic flushing of the adsorption plate 16 to ensure the adsorption effect of the adsorption plate 16 to adsorb floating dust, prevent the contaminated adsorption plate 16 from being difficult to efficiently adsorb dust, and indirectly improve the purification efficiency of industrial waste gas.

[0052] Embodiment 4:

[0053] Reference Figure 4-Figure 8 , which is basically the same as the third embodiment, and further, a specific implementation scheme for increasing the spraying area of ​​the nozzle 18 is specifically added.

[0054] The above-mentioned cross tube 17 is installed on the outer wall of the spray tower 1 in a transverse sliding manner, and one end of the cross tube 17 is fixedly connected to a limit plate 19, wherein a reciprocating spring 20 is installed between the limit plate 19 and the outer wall of the spray tower 1, and the outer wall of the vertical tube 4 is fixedly connected to a plurality of protrusions 21 arranged at equal intervals, the number of the protrusions 21 is 4-12, and the preferred number in this application is 6. When the vertical tube 4 rotates, the plurality of protrusions 21 will press the axial end of the cross tube 17 in turn.

[0055] Specifically, when the vertical pipe 4 rotates, the vertical pipe 4 will drive the multiple protrusions 21 to revolve around its axis, and the multiple protrusions 21 will press the ends of the cross pipe 17 in turn. When the cross pipe 17 is pressed by the protrusions 21, it will slide in the direction away from the protrusions 21. When the cross pipe 17 is not pressed, the reciprocating spring 20 will drive the cross pipe 17 to slide in the opposite direction and reset. Therefore, under the action of the multiple protrusions 21, the cross pipe 17 will slide back and forth and drive the nozzle 18 at the bottom to swing back and forth, thereby increasing the spraying area of ​​the nozzle 18 and improving the effect of flushing the adsorption plate 16, thereby indirectly ensuring the effect of adsorbing floating dust in the exhaust gas.

[0056] Embodiment five:

[0057] Reference Figure 4-Figure 8 , which is basically the same as the fourth embodiment, and further, a specific implementation scheme for making the adsorption plate 16 slide up and down is specifically added.

[0058] The above-mentioned adsorption plate 16 is longitudinally slidably installed in the mounting groove 15, and a lifting part is provided on the cross tube 17 to drive the adsorption plate 16 to move up and down in the mounting groove 15, and the lifting part includes an active magnet 25 fixedly installed at the lower end of the cross tube 17, and a driven magnet 24 is fixedly installed on the adsorption plate 16, and the opposite surface magnetic poles of the active magnet 25 and the driven magnet 24 are the same, wherein the inner wall of the mounting groove 15 is fixedly connected with a mounting seat 22, and a lifting spring 23 is installed between the adsorption plate 16 and the mounting seat 22.

[0059] Specifically, when the cross tube 17 slides back and forth, the cross tube 17 will also drive the active magnet 25 to reciprocate. When the active magnet 25 is located directly above the driven magnet 24, since the two have the same opposite magnetic poles, the driven magnet 24 will be subjected to a repulsive force and drive the adsorption plate 16 to slide downward. When the active magnet 25 is away from directly above the driven magnet 24, the lifting spring 23 will drive the adsorption plate 16 to slide upward and reset. Therefore, the reciprocating active magnet 25 will cause the adsorption plate 16 to slide up and down, and the adsorption plate 16 can shake off part of the liquid and dirt on the outer wall, thereby improving the flushing effect of the adsorption plate 16 and indirectly ensuring the effect of industrial waste gas purification.

[0060] A cross frame 26 is fixedly connected in the above-mentioned mounting groove 15, and a brush plate 27 is slidably installed on the cross frame 26. The brush on the brush plate 27 faces the outer wall of the adsorption plate 16, and the adsorption plate 16 is provided with a pushing part for driving the brush plate 27 to slide back and forth; the pushing part includes a pull rope 29 fixedly connected to the adsorption plate 16, and a pulley 28 is rotatably installed at the end of the cross frame 26. The end of the pull rope 29 is fixedly connected to the brush plate 27, and the middle part of the pull rope 29 is sleeved on the pulley 28, wherein a support plate 30 is fixedly connected to the end of the cross frame 26, and a reset spring 34 is installed between the brush plate 27 and the support plate 30.

[0061] Specifically, when the adsorption plate 16 slides up and down, the adsorption plate 16 intermittently pulls the pull rope 29, and the pull rope 29 pulls the brush plate 27 to slide toward the pulley 28. The brush plate 27 brushes the outer wall of the adsorption plate 16 through the brush, which can further improve the flushing effect of the adsorption plate 16. When the adsorption plate 16 no longer pulls the pull rope 29, the reset spring 34 drives the brush plate 27 to slide in the opposite direction and reset, and completes the secondary brushing of the adsorption plate 16.

[0062] A method for treating industrial waste gas, the operating steps are as follows:

[0063] Step 1: Pass the industrial waste gas into the smoke inlet 2 of the spray tower 1;

[0064] Step 2: Make the nozzle 6 continuously spray liquid, and make the vertical pipe 4 drive the nozzle 6 to revolve around its axis;

[0065] Step 3: While the nozzle 6 is in use, the nozzle 18 flushes the adsorption plate 16;

[0066] Step 4: Make the adsorption plate 16 revolve around the axis of the spray tower 1;

[0067] Step 5: discharge the industrial waste gas from the spray tower 1 through the smoke exhaust pipe 3 .

[0068] When in use, the present industrial waste gas treatment device will be introduced into the spray tower 1 from the smoke inlet 2, and the treated smoke will be discharged from the smoke exhaust pipe 3. While the smoke passes through the spray tower 1, the spray liquid is transported into the liquid inlet pipe 13, and the liquid enters the vertical pipe 4. Finally, it will be sprayed into the spray tower 1 from the nozzle 6 at the lower end of the nozzle 5 to perform dust reduction treatment on the smoke. When the smoke passes through the smoke exhaust pipe 3, the flowing smoke will drive the fan blades 9 to rotate, and the fan blades 9 will drive the rotating shaft 8 to rotate. The rotating shaft 8 will drive the transmission shaft 10 to rotate through two mutually meshing transmission gears 11, and the transmission shaft 10 will drive the vertical pipe 4 to rotate through the chain drive 12. The vertical pipe 4 will drive the nozzle 5 and the nozzle 6 at the lower end to revolve around their axis, thereby significantly increasing the spraying area of ​​the nozzle 6, thereby reducing the smoke directly passing through the spraying area, and improving the treatment effect of the industrial waste gas.

[0069] During the treatment of industrial waste gas, liquid enters the horizontal pipe 17, and the horizontal pipe 17 sprays the liquid onto the adsorption plate 16 through the nozzle 18. The rotating vertical pipe 4 drives the cylinder 14 to rotate, and the cylinder 14 drives multiple adsorption plates 16 to revolve around the axis of the vertical pipe 4, so that each adsorption plate 16 can be wetted by the liquid. The wetted adsorption plate 16 can further adsorb the particles in the waste gas to improve the treatment effect of the industrial waste gas. The adsorption plate 16 revolving around the axis of the vertical pipe 4 can significantly improve the efficiency of adsorbing floating dust, so that the efficiency of industrial waste gas treatment is higher.

[0070] When the nozzle 18 sprays liquid, it will also flush the adsorption plate 16. During the flushing, the wind shield 31 will block the lower end of the adsorption plate 16 to prevent the upward airflow from affecting the flushing effect. The sewage generated by the flushing will flow along the adsorption plate 16 into the wind shield 31, and will eventually flow into the bottom of the spray tower 1 through the reflux pipe 32, thereby realizing the automatic flushing of the adsorption plate 16 to ensure the adsorption effect of the adsorption plate 16 to adsorb floating dust, prevent the contaminated adsorption plate 16 from being difficult to efficiently adsorb dust, and indirectly improve the purification efficiency of industrial waste gas.

[0071] When the vertical pipe 4 rotates, the vertical pipe 4 will drive the multiple protrusions 21 to revolve around its axis, and the multiple protrusions 21 will press the ends of the cross pipe 17 in turn. When the cross pipe 17 is pressed by the protrusions 21, it will slide in the direction away from the protrusions 21. When the cross pipe 17 is not pressed, the reciprocating spring 20 will drive the cross pipe 17 to slide in the opposite direction and reset. Therefore, under the action of the multiple protrusions 21, the cross pipe 17 will slide back and forth and drive the nozzle 18 at the bottom to swing back and forth, thereby increasing the spraying area of ​​the nozzle 18 and improving the effect of flushing the adsorption plate 16, thereby indirectly ensuring the effect of adsorbing floating dust in the exhaust gas.

[0072] When the cross tube 17 slides back and forth, it will also drive the active magnet 25 to reciprocate. When the active magnet 25 is located directly above the driven magnet 24, since the magnetic poles of the two opposite surfaces are the same, the driven magnet 24 will be subjected to repulsive force and drive the adsorption plate 16 to slide downward. When the active magnet 25 is away from directly above the driven magnet 24, the lifting spring 23 will drive the adsorption plate 16 to slide upward and reset. Therefore, the reciprocating active magnet 25 will cause the adsorption plate 16 to slide up and down, and the adsorption plate 16 can shake off part of the liquid and dirt on the outer wall, thereby improving the flushing effect of the adsorption plate 16 and indirectly ensuring the effect of industrial waste gas purification.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
