Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of waste gas treatment devices, and in particular, to a waste gas treatment device for corrugated paper production. Background Art

[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper in a waveform formed by a corrugating roll. It is generally divided into four layers: a facing paper, a backing paper, a core paper, and a corrugated paper. It has the characteristics of low cost, light weight, and high strength, and is widely used in packaging fields, construction fields, furniture fields, etc.

[0003] Since corrugated paper production often uses waste paper as the main raw material, various odor substances may be adsorbed during the recycling and storage of waste paper. During the treatment of waste paper, these odors will volatilize with heating to form waste gas. If these waste gases are directly discharged without treatment, they will have an impact on the human body and the environment.

[0004] Therefore, after corrugated paper production is completed, the generated waste gas is usually collected and treated, and then discharged after treatment. When treating the waste gas, spraying the waste gas is one of the treatment methods. Water or a chemical solution is sprayed on the waste gas through a spraying nozzle, and the waste water is further purified through physical water absorption or chemical reaction.

[0005] However, when most spraying nozzles spray waste gas, the spraying nozzles are fixedly installed on the treatment tank and it is difficult to change the angle and position. Therefore, when spraying the solution, it is difficult to spray the waste gas in the treatment tank completely, resulting in a poor purification effect. Summary of the Invention

[0012] To ensure the protection of the first driving gear ring and the second driving gear ring during spraying, further, a support cover is detachably installed on the side of the mounting plate. Both the first driving gear ring and the second driving gear ring are located inside the support cover, and the driving shaft is rotatably installed through the support cover.

[0013] To ensure that when the high-pressure nozzle swings up and down, the connecting pipe does not block the movement of the high-pressure nozzle, further, the connecting pipe is provided as a flexible hose.

[0014] To ensure that when the water inlet pipe rotates, the water receiving pipe can smoothly follow the rotation, furthermore, the water receiving pipe is provided in an L shape, and the vertical portion of the water receiving pipe is located between the rotating ring and the treatment tower.

[0027] As Figures 1 to 6 shown, it shows an exhaust gas treatment device for corrugated paper production in an embodiment of this disclosure, which includes a treatment tower 1. An intake pipe 2 and an outlet pipe 3 are connected and installed on both sides of the treatment tower 1. It further includes a water inlet pipe 4, a support disc 5, a spraying assembly, a rotating assembly and an angle adjustment assembly. The water inlet pipe 4 is rotatably installed through the treatment tower 1. The support disc 5 is fixedly installed in the treatment tower 1, and the water inlet pipe 4 is rotatably installed through the support disc 5. Spraying assemblies are arranged on both sides of the water inlet pipe 4 for spraying the exhaust gas inhaled into the treatment tower 1. The rotating assembly is arranged on the treatment tower 1 for driving the water inlet pipe 4 and the spraying assemblies to rotate, so as to spray the exhaust gas evenly. An angle adjustment assembly is arranged on the spraying assembly for adjusting the spraying angle.

[0028] As Figure 2 、 Figure 4 and Figure 6As shown, after the corrugated cardboard box is produced, the exhaust gas generated is collected through the air collecting hood, and then introduced into the treatment tower 1 through the air inlet pipe 2. After being introduced, the exhaust gas in the treatment tower 1 is sprayed by the spraying assembly. The spraying assembly includes high-pressure nozzles 6, connecting pipes 7 and water receiving pipes 8. A number of high-pressure nozzles 6 are provided, and a number of high-pressure nozzles 6 are all arranged on the side of the water inlet pipe 4 through a rotating assembly. Connecting pipes 7 are connected and installed between the high-pressure nozzles 6 and the water inlet pipe 4. The water receiving pipe 8 is connected and installed on the side of the water inlet pipe 4. The rotating assembly includes a mounting plate 9 and a rotating shaft 10. Two mounting plates 9 are provided, and both of the two mounting plates 9 are fixedly installed on the side of the water inlet pipe 4. The rotating shaft 10 is rotatably installed between the two mounting plates 9, and the high-pressure nozzle 6 is fixedly installed on the side of the rotating shaft 10 through a connecting block. Specifically, after the water source enters the water inlet pipe 4, it enters the high-pressure nozzle 6 through the connecting pipe 7, and the high-pressure nozzle 6 can spray the water source to contact the exhaust gas.

[0029] As Figure 3 shown, after spraying is completed at one position, the water inlet pipe 4 can be rotated through the rotating assembly, thereby driving the high-pressure nozzle 6 to rotate and changing the spraying position. The rotating assembly includes a rotating ring 11, a rotating frame 12, a support frame 13 and a first motor 14. The rotating ring 11 is fixedly installed on the treatment tower 1, and a chute is provided on the inner side wall of the rotating ring 11. The rotating frame 12 is rotatably installed in the chute of the rotating ring 11, and the top end of the water inlet pipe 4 is fixedly connected to the bottom end of the rotating frame 12. The support frame 13 is fixedly installed on the rotating ring 11, the first motor 14 is installed at the top end of the support frame 13, and the output end of the first motor 14 is fixedly connected to the top end of the rotating frame 12.

[0030] Specifically, by starting the first motor 14, the output end of the first motor 14 drives the rotating frame 12 to rotate in the chute of the rotating ring 11. The rotating frame 12 drives the water inlet pipe 4 to rotate in the treatment tower 1, and the water inlet pipe 4 can rotate synchronously on the support disc 5. Then the high-pressure nozzle 6 changes its position driven by the water inlet pipe 4. When rotating, the water pump connected to the water receiving pipe 8 beside the treatment tower 1 can be moved to move synchronously with the water receiving pipe 8. And the water receiving pipe 8 is set to be L-shaped, and the vertical part of the water receiving pipe 8 is located between the rotating ring 11 and the treatment tower 1. One end of the L-shaped water receiving pipe 8 can be connected to the water inlet pipe 4, and the other end can be located between the rotating ring 11 and the treatment tower 1 and connected to the water pump at the bottom end. And when rotating, there will also be space for rotation.

[0031] As Figure 5As shown, during spraying, the angle of the high-pressure nozzle 6 can also be changed by an angle adjustment assembly, which includes a drive gear ring 15, a drive gear ring 2 16, a second motor 17 and a drive shaft 18. The drive gear ring 15 is fixedly mounted on the rotating shaft 10, the drive gear ring 2 16 is meshed with the drive gear ring 15, the second motor 17 is mounted on the top of the supporting disc 5, the top of the drive shaft 18 is fixedly connected to the output end of the second motor 17, and the drive gear ring 2 16 is fixedly mounted on the drive shaft 18.

[0032] Specifically, by starting the second motor 17, the output end of the second motor 17 drives the driving shaft 18 to rotate, the driving shaft 18 drives a plurality of driving gear rings 16 to rotate, the driving gear rings 16 drive the driving gears 1 meshing therewith to rotate, the driving gears 1 drive the rotating shaft 10 to rotate, the rotating shaft 10 drives the high-pressure nozzle 6 to swing up and down, thereby changing the spraying angle, and further spraying the exhaust gas in other parts of the treatment tower 1, because the side of the mounting plate 9 is detachably mounted with a support cover 19, the driving gear rings 15 and the driving gear rings 2 16 are both located in the support cover 19, and The driving shaft 18 is rotatably installed on the support cover 19, and the support cover 19 can support the driving shaft 18, and during spraying, the driving gear ring 15 and the driving gear ring 2 16 can be located in the support cover 19 for protection to prevent the sprayed medicine or water source from being attached to the driving gear ring 15 and the driving gear ring 2 16 and causing them to rust, and the connecting pipe 7 is configured as a hose. When the high-pressure nozzle 6 swings up and down, the connecting pipe 7 is a hose, so the hose can bend after the high-pressure nozzle 6 swings. After the high-pressure nozzle 6 is swung, the water source can still enter the high-pressure nozzle 6 through the connecting pipe 7.

[0033] Working principle: When treating waste gas, first, the waste gas is introduced into the treatment tower 1 through the intake pipe 2 on the side of the treatment tower 1 by an air suction pump. Then, the water connection pipe 8 is connected to a water suction pump, and the water source is sucked up by the water suction pump and enters the intake pipe 4 through the water connection pipe 8. After the water source enters the intake pipe 4, it enters the high-pressure nozzle 6 through the connecting pipe 7. The high-pressure nozzle 6 can spray the water source to contact the waste gas, thereby purifying the waste gas. After the high-pressure nozzle 6 sprays at a position for a period of time, by starting the first motor 14, the output end of the first motor 14 drives the rotating frame 12 to rotate in the sliding groove of the rotating ring 11. The rotating frame 12 drives the intake pipe 4 to rotate in the treatment tower 1, and the intake pipe 4 can rotate synchronously on the support disc 5. Then, the high-pressure nozzle 6 changes its position under the drive of the intake pipe 4, so that the high-pressure nozzle 6 rotates to other positions, changing the spraying orientation, thereby spraying the waste gas more comprehensively. And while spraying, the second motor 17 can be started. The output end of the second motor 17 drives the drive shaft 18 to rotate. The drive shaft 18 drives a number of second drive gear rings 16 to rotate. The second drive gear rings 16 drive the first drive gears meshing with them to rotate. The first drive gears drive the rotating shaft 10 to rotate. The rotating shaft 10 drives the high-pressure nozzle 6 to swing up and down, thereby changing the spraying angle and further spraying the waste gas in other parts of the treatment tower 1. The support cover 19 on the side of the mounting plate 9 can support the drive shaft 18, and when spraying, the first drive gear ring 15 and the second drive gear rings 16 can be protected inside the support cover 19. After spraying is completed, the waste gas after spraying is sucked out through the exhaust pipe 3 on the side of the treatment tower 1 and sucked into the next process for further treatment of the waste gas in the next process.

[0034] It should be added that the rotating frame 12 is set in a U shape. The two ends of the rotating frame 12 are slidably installed in the sliding groove of the rotating ring 11. The top end of the intake pipe 4 is fixedly connected to the central part of the rotating frame 12, and the output end of the first motor 14 is fixedly connected to the central part of the top end of the rotating frame 12. Therefore, when rotating, the intake pipe 4 can rotate around the center of the treatment tower 1 in the treatment tower 1, making the spraying more uniform. And the high-pressure nozzle 6, the intake pipe 2, and the exhaust pipe 3 are all located below the support disc 5. The waste gas purification spraying and suction are all carried out below the support disc, and it will not contact the second motor 17.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not restrictive. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered by the scope of the claims of the present disclosure.
