Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to an industrial waste gas treatment device and treatment method. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, lead and mercury sulfate, beryllium compounds, soot, and industrial dust, etc. Among these, dust is mainly purified through spray equipment.

[0003] In the existing technology, the internal structure of the spray equipment used to treat industrial waste gas is relatively simple. It mainly completes the dust suppression and removal work by spraying liquid from a large number of nozzles. Since most of the nozzles are fixed, some flue gas will pass directly through the spray area without being adsorbed by the liquid, which makes it difficult to guarantee the purification effect of industrial waste gas. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the prior art, since most nozzles are in a fixed state, it is difficult to guarantee the purification effect of industrial waste gas. Therefore, this invention proposes an industrial waste gas treatment device and treatment method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An industrial waste gas treatment device includes a spray tower with a smoke inlet and a smoke exhaust pipe, and a vertical pipe rotatably installed inside the spray tower via a support. The outer wall of the spray tower is fixedly connected to a liquid inlet pipe communicating with the upper end of the vertical pipe. Multiple spray pipes distributed circumferentially are fixedly installed at the lower end of the vertical pipe, and each of the multiple spray pipes has a nozzle fixedly installed at its lower end. The spray tower is provided with a drive unit for driving the vertical pipe to rotate.

[0007] To enable the nozzles to revolve around the axis of the spray tower, preferably, the drive unit includes a device box fixedly connected to the side wall of the exhaust pipe. Inside the device box, fan blades extending into the exhaust pipe are rotatably installed via a rotating shaft. A drive shaft is rotatably connected to the spray tower. The upper end of the drive shaft is connected to the rotating shaft via two meshing drive gears. The drive shaft is connected to the vertical pipe via a chain drive.

[0008] To improve the treatment effect of industrial waste gas, preferably, a cylinder is rotatably installed on the inner top of the spray tower and fixedly connected to the vertical pipe. The upper end of the cylinder is provided with multiple circumferentially distributed mounting slots, and an adsorption plate is installed in each of the multiple mounting slots. A horizontal pipe extending into the outer wall of the spray tower is inserted laterally, and a nozzle is fixedly installed at the lower end of the horizontal pipe. A wind baffle is fixedly connected to the lower inner wall of the spray tower, and the nozzle faces inward toward the wind baffle. A return pipe extending to the bottom of the spray tower is fixedly connected to the bottom of the wind baffle.

[0009] To improve the spraying of cotton from the nozzle, the horizontal tube is further slidably installed on the outer wall of the spray tower. One end of the horizontal tube is fixedly connected to a limiting plate. A reciprocating spring is installed between the limiting plate and the outer wall of the spray tower. The outer wall of the vertical tube is fixedly connected to a plurality of equally spaced protrusions. When the vertical tube rotates, the plurality of protrusions will press against the shaft end of the horizontal tube in sequence.

[0010] To further improve the rinsing effect on the adsorption plate, the adsorption plate is slidably installed longitudinally in the mounting groove, and the horizontal tube is provided with a lifting part to drive the adsorption plate to move up and down in the mounting groove.

[0011] To enable the adsorption plate to move up and down during rinsing, the lifting part further includes an active magnet fixedly installed at the lower end of the horizontal tube, a driven magnet fixedly installed on the adsorption plate, the opposite magnetic poles of the active magnet and the driven magnet being the same, wherein a mounting base is fixedly connected to the inner wall of the mounting groove, and a lifting spring is installed between the adsorption plate and the mounting base.

[0012] To further clean the outer wall of the adsorption plate, a crossbeam is fixedly connected in the mounting groove, and a brush plate is slidably mounted on the crossbeam. The brushes on the brush plate face the outer wall of the adsorption plate, and the adsorption plate is provided with a pushing part that drives the brush plate to slide back and forth.

[0013] To further clean the outer wall of the adsorption plate, the pushing part includes a pull rope fixedly connected to the adsorption plate, a pulley rotatably mounted at the end of the crossbeam, the end of the pull rope being fixedly connected to the brush plate, and the middle part of the pull rope being sleeved on the pulley. A support plate is fixedly connected to the end of the crossbeam, and a return spring is installed between the brush plate and the support plate.

[0014] To facilitate the discharge of wastewater from the bottom of the spray tower, preferably, a drain pipe is fixedly connected to the lower side wall of the spray tower, and the flue gas inlet is located above the drain pipe.

[0015] An industrial waste gas treatment method, the operation steps are as follows:

[0016] Step 1: Introduce industrial waste gas into the inlet of the spray tower;

[0017] Step 2: Make the nozzle continuously spray liquid and make the vertical pipe drive the nozzle to revolve around its axis;

[0018] Step 3: During the use of the nozzle, rinse the adsorption plate with the nozzle;

[0019] Step 4: Make the adsorption plate revolve around the axis of the spray tower;

[0020] Step 5: Discharge the industrial waste gas from the exhaust pipe into the spray tower.

[0021] Compared with the prior art, the present invention provides an industrial waste gas treatment device, which has the following beneficial effects:

[0022] 1. This industrial waste gas treatment device uses the flowing flue gas to drive the fan blades to rotate, and the vertical pipe drives the lower nozzle and spray head to revolve around its axis, thereby significantly increasing the spray area of ​​the nozzle and reducing the amount of flue gas that directly passes through the spray area, thus improving the treatment effect of industrial waste gas.

[0023] 2. This industrial waste gas treatment device can further adsorb particles in the waste gas by wetting the adsorption plate, thereby improving the treatment effect of industrial waste gas. The adsorption plate revolving around the vertical pipe axis can significantly improve the efficiency of adsorbing floating dust, making the treatment efficiency of industrial waste gas even higher.

[0024] 3. This industrial waste gas treatment device also washes the adsorption plate when the nozzle sprays liquid. The wind shield blocks the lower end of the adsorption plate to prevent the upward airflow from affecting the washing effect, thereby realizing the automatic washing of the adsorption plate. This ensures the adsorption plate's ability to adsorb floating dust and prevents the contaminated adsorption plate from being unable to efficiently adsorb dust, thus indirectly improving the purification efficiency of industrial waste gas.

[0025] 4. This industrial waste gas treatment device, through the action of multiple protrusions, causes the horizontal pipe to slide back and forth, which in turn drives the nozzle at the bottom to swing back and forth, thereby increasing the spray area of ​​the nozzle and improving the washing effect of the adsorption plate, indirectly ensuring the adsorption effect of floating dust in the waste gas.

[0026] 5. This industrial waste gas treatment device uses a reciprocating sliding active magnet to make the adsorption plate slide up and down, which can shake off some of the liquid and dirt on the outer wall of the adsorption plate, thereby improving the rinsing effect of the adsorption plate and indirectly ensuring the purification effect of industrial waste gas.

[0027] 6. This industrial waste gas treatment device, by intermittently pulling the rope on the adsorption plate, will cause the brush plate to slide towards the pulley, and the brush plate will scrub the outer wall of the adsorption plate, thereby further improving the rinsing effect on the adsorption plate.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Example 1:

[0040] Reference Figures 1-8 An industrial waste gas treatment device includes a spray tower 1 with a smoke inlet 2 and a smoke exhaust pipe 3, and a vertical pipe 4 rotatably installed inside the spray tower 1 via a support. The outer wall of the spray tower 1 is fixedly connected to a liquid inlet pipe 13 that communicates with the upper end of the vertical pipe 4. The liquid inlet pipe 13 is used to supply water to the vertical pipe 4. The lower end of the vertical pipe 4 is fixedly installed with multiple circumferentially distributed spray pipes 5. The number of spray pipes 5 is 3 to 12, and the preferred number in this application is 3. The lower end of each spray pipe 5 is fixedly installed with a spray nozzle 6 for spraying. The spray tower 1 is provided with a drive unit for driving the vertical pipe 4 to rotate.

[0041] During use, the flue gas is introduced into the spray tower 1 through the inlet 2. The treated flue gas is discharged from the exhaust pipe 3. During the passage of the flue gas through the spray tower 1, spray liquid is delivered into the liquid inlet pipe 13. The liquid enters the vertical pipe 4 and is finally sprayed into the spray tower 1 from the nozzle 6 at the lower end of the spray pipe 5 for dust suppression. When the flue gas passes through the exhaust pipe 3, the drive unit drives the vertical pipe 4 to rotate. The vertical pipe 4 then drives the lower nozzle 5 and nozzle 6 to revolve around its axis, thereby significantly increasing the spray area of ​​the nozzle 6 and reducing the direct passage of flue gas through the spray area, thus improving the treatment effect of industrial waste gas.

[0042] The lower side wall of the above-mentioned spray tower 1 is fixedly connected to 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. Therefore, the sewage generated by the spraying will remain at the 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 the excess sewage through the sewage pipe 33.

[0043] Example 2:

[0044] Reference Figures 3-4 Similar to Embodiment 1, but further, a specific implementation scheme for the drive unit is disclosed.

[0045] The aforementioned drive unit includes a device box 7 fixedly connected to the side wall of the exhaust pipe 3. Inside the device box 7, a fan blade 9 extending into the exhaust pipe 3 is rotatably installed via a rotating shaft 8. A drive shaft 10 is rotatably connected to the spray tower 1. The upper end of the drive shaft 10 is connected to the rotating shaft 8 via two meshing drive gears 11. The drive shaft 10 is connected to the vertical pipe 4 via a chain drive 12.

[0046] Specifically, when the flue gas passes through the exhaust pipe 3, the flowing flue gas will drive the fan blades 9 to rotate, which in turn will drive the rotating shaft 8 to rotate. The rotating shaft 8 will drive the transmission shaft 10 to rotate through two meshing transmission gears 11. The transmission shaft 10 will then drive the vertical pipe 4 to rotate through the chain drive 12. The vertical pipe 4 will then drive the lower nozzle 5 and the nozzle 6 to revolve around its axis, thereby significantly increasing the spray area of ​​the nozzle 6, thereby reducing the direct passage of flue gas through the spray area and improving the treatment effect of industrial waste gas.

[0047] Example 3:

[0048] Reference Figures 3-8 The implementation is basically the same as in Example 2, but with a further addition of a specific implementation plan to improve the treatment effect of industrial waste gas.

[0049] The inner top of the spray tower 1 is rotatably mounted with a cylinder 14 fixedly connected to the vertical pipe 4. The upper end of the cylinder 14 is provided with a plurality of circumferentially distributed mounting slots 15. Each mounting slot 15 is equipped with an adsorption plate 16. The surface of the adsorption plate 16 is an uneven, non-flat surface. A horizontal pipe 17 extending into the outer wall of the spray tower 1 is inserted laterally. A nozzle 18 is fixedly mounted at the lower end of the horizontal pipe 17. A wind baffle 31 is fixedly connected to the lower inner wall of the spray tower 1. The nozzle 18 faces into the wind baffle 31. A return pipe 32 extending into the bottom of the spray tower 1 is fixedly connected to the bottom of the wind baffle 31.

[0050] During the treatment of industrial waste gas, liquid is introduced into the horizontal pipe 17, which sprays the liquid onto the adsorption plates 16 through the nozzles 18. The rotating vertical pipe 4 drives the cylinder 14 to rotate, which in turn drives multiple adsorption plates 16 to revolve around the axis of the vertical pipe 4. This ensures that each adsorption plate 16 is wetted by the liquid. The wetted adsorption plates 16 can further adsorb particles in the waste gas, thereby improving the treatment effect of industrial waste gas. The adsorption plates 16 revolving around the axis of the vertical pipe 4 can significantly improve the efficiency of adsorbing floating dust, making the treatment efficiency of industrial waste gas even higher.

[0051] When the nozzle 18 sprays liquid, it also washes the adsorption plate 16. During the washing process, the baffle 31 blocks the lower end of the adsorption plate 16 to prevent the upward airflow from affecting the washing effect. The wastewater generated during washing flows along the adsorption plate 16 into the baffle 31 and then flows into the bottom of the spray tower 1 through the return pipe 32, thereby realizing the automatic washing of the adsorption plate 16. This ensures the adsorption plate 16's adsorption effect on floating dust and prevents the contaminated adsorption plate 16 from being unable to efficiently adsorb dust, thus indirectly improving the purification efficiency of industrial waste gas.

[0052] Example 4:

[0053] Reference Figures 4-8 The implementation is basically the same as in Example 3, but with a further addition: a specific implementation plan to increase the spray area of ​​nozzle 18.

[0054] The horizontal tube 17 is slidably installed on the outer wall of the spray tower 1. One end of the horizontal tube 17 is fixedly connected to a limiting plate 19. A reciprocating spring 20 is installed between the limiting plate 19 and the outer wall of the spray tower 1. A plurality of equally spaced protrusions 21 are fixedly connected to the outer wall of the vertical tube 4. The number of protrusions 21 is 4 to 12. In this application, the preferred number is 6. When the vertical tube 4 rotates, the plurality of protrusions 21 will press against the shaft end of the horizontal tube 17 in sequence.

[0055] Specifically, when the vertical tube 4 rotates, it will cause multiple protrusions 21 to revolve around its axis. The multiple protrusions 21 will press against the end of the horizontal tube 17 in turn. When the horizontal tube 17 is pressed by the protrusions 21, it will slide away from the protrusions 21. When the horizontal tube 17 is not pressed, the reciprocating spring 20 will drive the horizontal tube 17 to slide back to its original position. Thus, under the action of the multiple protrusions 21, the horizontal tube 17 will slide back and forth, and drive the nozzle 18 at the bottom to swing back and forth, which can increase the spray area of ​​the nozzle 18, improve the washing effect of the adsorption plate 16, and indirectly ensure the adsorption effect of dust in the exhaust gas.

[0056] Example 5:

[0057] Reference Figures 4-8 The implementation is basically the same as in Example 4, but with a further addition: a specific implementation scheme is added to allow the adsorption plate 16 to slide up and down.

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

[0059] Specifically, as the horizontal tube 17 slides back and forth, it also drives the active magnet 25 to slide back and forth. When the active magnet 25 is directly above the driven magnet 24, since the magnetic poles of the two are the same, the driven magnet 24 will be subjected to a repulsive force, which will 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. Thus, the reciprocating active magnet 25 will cause the adsorption plate 16 to slide up and down, and the adsorption plate 16 can shake off some of the liquid and dirt on the outer wall, thereby improving the rinsing effect of the adsorption plate 16 and indirectly ensuring the purification effect of industrial waste gas.

[0060] A crossbeam 26 is fixedly connected in the mounting groove 15. A brush plate 27 is slidably mounted on the crossbeam 26. The brushes on the brush plate 27 face the outer wall of the adsorption plate 16. The adsorption plate 16 is provided with a pushing part that drives the brush plate 27 to slide back and forth. The pushing part includes a pull rope 29 fixedly connected to the adsorption plate 16. A pulley 28 is rotatably mounted at the end of the crossbeam 26. The end of the pull rope 29 is fixedly connected to the brush plate 27. The middle part of the pull rope 29 is sleeved on the pulley 28. A support plate 30 is fixedly connected to the end of the crossbeam 26. A return 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, which in turn pulls the brush plate 27 towards the pulley 28. The brush plate 27 then brushes the outer wall of the adsorption plate 16, thereby further improving the rinsing effect on the adsorption plate 16. When the adsorption plate 16 stops pulling the pull rope 29, the reset spring 34 will drive the brush plate 27 to slide back and reset, completing the secondary brushing of the adsorption plate 16.

[0062] An industrial waste gas treatment method, the operation steps are as follows:

[0063] Step 1: Introduce industrial waste gas into the flue gas 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: During the use of nozzle 6, rinse the adsorption plate 16 with nozzle 18;

[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 exhaust pipe 3 to the spray tower 1.

[0068] In operation, this industrial waste gas treatment device introduces the flue gas into the spray tower 1 through the inlet 2. The treated flue gas is then discharged through the exhaust pipe 3. During the passage of the flue gas through the spray tower 1, spray liquid is supplied into the liquid inlet pipe 13. The liquid enters the vertical pipe 4 and is finally sprayed into the spray tower 1 from the nozzle 6 at the lower end of the spray pipe 5 for dust suppression. As the flue gas passes through the exhaust pipe 3, the flowing flue gas drives the fan blades 9 to rotate, which in turn drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the transmission shaft 10 to rotate through two meshing transmission gears 11. The transmission shaft 10 drives the vertical pipe 4 to rotate through the chain drive 12. The vertical pipe 4 then drives the lower nozzle 5 and nozzle 6 to revolve around its axis, thereby significantly increasing the spray area of ​​the nozzle 6 and reducing the direct passage of flue gas through the spray area, thus improving the treatment effect of industrial waste gas.

[0069] During the treatment of industrial waste gas, liquid is introduced into the horizontal pipe 17, which sprays the liquid onto the adsorption plates 16 through the nozzles 18. The rotating vertical pipe 4 drives the cylinder 14 to rotate, which in turn drives multiple adsorption plates 16 to revolve around the axis of the vertical pipe 4. This ensures that each adsorption plate 16 is wetted by the liquid. The wetted adsorption plates 16 can further adsorb particles in the waste gas, thereby improving the treatment effect of industrial waste gas. The adsorption plates 16 revolving around the axis of the vertical pipe 4 can significantly improve the efficiency of adsorbing floating dust, making the treatment efficiency of industrial waste gas even higher.

[0070] When the nozzle 18 sprays liquid, it also washes the adsorption plate 16. During the washing process, the baffle 31 blocks the lower end of the adsorption plate 16 to prevent the upward airflow from affecting the washing effect. The wastewater generated during washing flows along the adsorption plate 16 into the baffle 31 and then flows into the bottom of the spray tower 1 through the return pipe 32, thereby realizing the automatic washing of the adsorption plate 16. This ensures the adsorption plate 16's adsorption effect on floating dust and prevents the contaminated adsorption plate 16 from being unable to efficiently adsorb dust, thus indirectly improving the purification efficiency of industrial waste gas.

[0071] When the vertical tube 4 rotates, it drives multiple protrusions 21 to revolve around its axis. The multiple protrusions 21 then press against the end of the horizontal tube 17 in turn. When the horizontal tube 17 is pressed by the protrusions 21, it slides away from the protrusions 21. When the horizontal tube 17 is not pressed, the reciprocating spring 20 drives the horizontal tube 17 to slide back to its original position. Thus, under the action of the multiple protrusions 21, the horizontal tube 17 slides back and forth, and drives the nozzle 18 at the bottom to swing back and forth, which can increase the spray area of ​​the nozzle 18, improve the washing effect of the adsorption plate 16, and indirectly ensure the adsorption effect of floating dust in the exhaust gas.

[0072] As the horizontal tube 17 slides back and forth, it also drives the active magnet 25 to slide back and forth. When the active magnet 25 is 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 a repulsive force, which will 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. Thus, the reciprocating active magnet 25 will cause the adsorption plate 16 to slide up and down, and the adsorption plate 16 can shake off some of the liquid and dirt on the outer wall, thereby improving the rinsing effect of the adsorption plate 16 and indirectly ensuring the purification effect of industrial waste gas.

[0073] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
