Common ones include benzene, toluene, ethylbenzene, xylene, etc. They are widely present in waste gases in the petroleum, chemical, printing, paint, coating, solvent and other industries.

[0003] Since VOC gas has a direct irritating and harmful effect on the human body, long-term exposure to a high concentration of VOC environment may cause damage to the brain and nervous system, and even lead to serious consequences such as poisoning. Therefore, a waste gas treatment device is needed to treat VOC organic waste gas.

[0004] At present, when treating VOC organic waste gas, activated carbon adsorption and spraying treatment are usually used to make VOC organic waste gas harmless. During activated carbon adsorption, after the waste gas passes through the activated carbon filter plate, the activated carbon will adsorb harmful substances and make the adsorption effect of the activated carbon worse. The current waste gas treatment device, its activated carbon filter plate cannot fully contact with the waste gas, and often there is a problem that the corner area of ​​the waste filter plate cannot be contacted or can only be contacted with a small amount of waste gas, so the filter plate needs to be replaced frequently, so it needs to be improved and optimized.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 8 As shown, the utility model provides a VOC organic waste gas treatment device, including an adsorption box 1, a spray box 2 is fixedly installed on the right side of the adsorption box 1, the adsorption box 1 and the spray box 2 are connected to each other through a ventilation pipe 3, a negative pressure fan 4 is fixedly installed on the left side of the adsorption box 1, the negative pressure fan 4 and the adsorption box 1 are connected to each other, and a sealed box door 5 is rotatably installed on the front side of the adsorption box 1;

[0029] A rotating shaft 6 is rotatably installed on the left inner wall of the adsorption box 1, and a rotating shaft 2 8 is rotatably installed on the right inner wall of the adsorption box 1. Mounting grooves 7 are provided on the front and rear sides of the rotating shaft 1 6 and the rotating shaft 2 8. An activated carbon filter 10 is detachably installed inside the adsorption box 1, and mounting plates 11 are fixedly installed on both the left and right ends of the activated carbon filter 10. A protrusion 12 is provided on the front and rear sides of the two sets of mounting plates 11, and the left mounting plate 11 is clamped to the inside of the rotating shaft 6 through the protrusion 12, and the right mounting plate 11 is clamped to the inside of the rotating shaft 2 8 through the protrusion 12. A driving block 26 is fixedly installed on the right side of the right mounting plate 11, and a driving groove 9 is provided inside the rotating shaft 2 8, and the driving block 26 is located inside the driving groove 9.

[0030] When it is necessary to treat the VOC organic waste gas, the staff starts the negative pressure fan 4 and the motor 19. The operation of the negative pressure fan 4 will suck the waste into the interior of the adsorption box 1 and the waste gas is now inside the activated carbon filter 10. The operation of the motor 19 drives the transmission shaft 20 to rotate, and through the transmission of the transmission belt 21, the drive shaft 15 starts to rotate synchronously. Since the guide block 17 is movably installed in the guide groove 16, the guide block 17 drives the rotating shaft 2 8 to rotate. Further, the rotating shaft 2 8 drives the driving block 26 to rotate through the driving groove 9. At this time, the activated carbon filter 10 rotates. Since the ventilation pipe 3 is located at the top of the adsorption box 1, the activated carbon filter The exhaust gas inside the net 10 is filtered out from the top of the activated carbon filter 10 and enters the interior of the ventilation pipe 3. The rotation of the activated carbon filter 10 will continuously change the filtering position of the activated carbon filter 10, so that each surface of the activated carbon filter 10 can filter the exhaust gas. At this time, the exhaust gas is discharged into the interior of the spray box 2 through the air supply port 22. Then the staff opens the valve of the spray pipe 23 to start the spraying operation of the spray pipe 23. The exhaust gas is filtered again upward by the filter plate 25. At the same time, the filter plate 25 will block the escape of the exhaust gas, so that the spray liquid can fully contact with the exhaust gas. After the exhaust gas treatment is completed, the clean gas is discharged from the exhaust port 24 to complete the collection;

[0031] After the treatment is completed, the activated carbon filter 10 needs to be removed to facilitate the desorption operation of the activated carbon filter 10. At this time, the staff stops the negative pressure fan 4 and the motor 19, and after the drive shaft 15 stops rotating, rotates the bolt 18. The bolt 18 drives the rotating shaft 2 8 to move to the right. The rotating shaft 2 8 is further retracted into the inside of the drive shaft 15, so that the mounting plate 11 on the right is completely disassembled. Then the staff pulls out the activated carbon filter 10 to the right. During the disassembly process, since the fixed end of the fixing head 13 is dome-shaped, the fixing head 13 will be squeezed into the inside of the protrusion 12 to complete the disassembly operation.

[0032] The drive shaft 15 is rotated by the operation of the motor 19 and the transmission of the transmission belt 21. At the same time, the activated carbon filter 10 rotates to adsorb the exhaust gas inside it. The rotation of the bolt 18 causes the rotating shaft 28 to move to the right. At this time, the staff can remove the mounting plates 11 on both sides of the activated carbon filter 10. Compared with the traditional device, the device continuously changes the filtering position of the activated carbon filter 10 through the rotation of the activated carbon filter 10, so that each side of the activated carbon filter 10 can filter the exhaust gas, and the exhaust gas and the activated carbon filter 10 are in full contact, thereby improving the filtering effect. Finally, the activated carbon filter 10 can be removed by rotating the bolt 18, thereby improving the work efficiency of the subsequent desorption treatment.

[0033] One end of the vent pipe 3 passes through the interior of the spray box 2, and an air supply port 22 is provided at the top of the vent pipe 3;

[0034] A filter plate 25 is fixedly mounted on the inner wall of the spray box 2 , and the filter plate 25 is located above the ventilation pipe 3 . A spray pipe 23 is fixedly mounted inside the spray box 2 , and the spray pipe 23 is located above the filter plate 25 . An exhaust port 24 is provided at the top of the spray box 2 .

[0035] The waste gas is discharged into the interior of the spray box 2 through the air supply port 22, and then the staff opens the valve of the spray pipe 23 to start the spraying operation of the spray pipe 23. The waste gas is filtered again by the filter plate 25 upward. At the same time, the filter plate 25 will block the escape of the waste gas, so that the spray liquid can fully contact with the waste gas. After the waste gas treatment is completed, the clean gas is discharged from the exhaust port 24 to complete the collection.

[0036] The waste gas discharged from the air supply port 22 is sprayed through the spray pipe 23, and the filter plate 25 is set to allow the waste gas to be filtered for a second time. At the same time, the filter plate 25 reduces the escape speed of the waste, further allowing the spray liquid to fully contact the waste gas, thereby improving the treatment quality of the waste gas.

[0037] A fixing head 13 is movably installed inside the protrusion 12 , and one end of the fixing head 13 is elastically connected to the protrusion 12 via a spring 14 .

[0038] Since the fixed end of the fixing head 13 is dome-shaped, the fixing head 13 will be squeezed into the inside of the protrusion 12 to complete the disassembly operation. During installation, the fixing head 13 will abut against the installation groove 7 through the elastic potential energy of the spring 14 to complete the fixing of the mounting plate 11.

[0039] Among them, a drive shaft 15 is rotatably installed on the right side wall of the adsorption box 1, and guide grooves 16 are provided at the upper and lower ends inside the drive shaft 15. A guide block 17 is movably installed inside the guide groove 16, and the guide block 17 is fixedly connected to the rotating shaft 28.

[0040] The guide groove 16 and the guide block 17 cooperate to limit the moving path of the rotating shaft 2 8 .

[0041] A bolt 18 is rotatably mounted on the outer wall of the driving shaft 15 , one end of the bolt 18 passes through the interior of the second rotating shaft 8 , and the bolt 18 and the second rotating shaft 8 are threadedly connected.

[0042] The rotation of the bolt 18 drives the rotating shaft 2 8 to move left and right. When the rotating shaft 2 8 moves to the left, the rotating shaft 2 8 and the rotating shaft 1 6 clamp the activated carbon filter 10 to complete the installation. When the rotating shaft 2 8 moves to the right, the mounting plate 11 is separated from the interior of the rotating shaft 2 8 to complete the disassembly.

[0043] Among them, a transmission shaft 20 is rotatably installed on the outer wall of the adsorption box 1, and the transmission shaft 20 and the drive shaft 15 are connected through a transmission belt 21. A motor 19 is fixedly installed on the right side of the adsorption box 1, and the output shaft of the motor 19 is fixedly connected to the transmission shaft 20.

[0044] The operation of the motor 19 drives the transmission shaft 20 to rotate, and through the transmission of the transmission belt 21, the drive shaft 15 starts to rotate synchronously.

[0045] The fixing end of the fixing head 13 is dome-shaped, and the fixing end of the fixing head 13 and the mounting groove 7 abut against each other.

[0046] During installation, the fixing head 13 will contact the installation groove 7 through the elastic potential energy of the spring 14, so that the installation plate 11 is fixed.

[0047] The working principle and use process of this utility model:

[0048] When it is necessary to treat the VOC organic waste gas, the staff starts the negative pressure fan 4 and the motor 19. The operation of the negative pressure fan 4 will suck the waste into the interior of the adsorption box 1 and the waste gas is now inside the activated carbon filter 10. The operation of the motor 19 drives the transmission shaft 20 to rotate, and through the transmission of the transmission belt 21, the drive shaft 15 starts to rotate synchronously. Since the guide block 17 is movably installed in the guide groove 16, the guide block 17 drives the rotating shaft 2 8 to rotate. Further, the rotating shaft 2 8 drives the driving block 26 to rotate through the driving groove 9. At this time, the activated carbon filter 10 rotates. Since the ventilation pipe 3 is located at the top of the adsorption box 1, the activated carbon filter The exhaust gas inside the net 10 is filtered out from the top of the activated carbon filter 10 and enters the interior of the ventilation pipe 3. The rotation of the activated carbon filter 10 will continuously change the filtering position of the activated carbon filter 10, so that each surface of the activated carbon filter 10 can filter the exhaust gas. At this time, the exhaust gas is discharged into the interior of the spray box 2 through the air supply port 22. Then the staff opens the valve of the spray pipe 23 to start the spraying operation of the spray pipe 23. The exhaust gas is filtered again upward by the filter plate 25. At the same time, the filter plate 25 will block the escape of the exhaust gas, so that the spray liquid can fully contact with the exhaust gas. After the exhaust gas treatment is completed, the clean gas is discharged from the exhaust port 24 to complete the collection;

[0049] After the treatment is completed, the activated carbon filter 10 needs to be removed to facilitate the desorption operation of the activated carbon filter 10. At this time, the staff stops the negative pressure fan 4 and the motor 19, and after the drive shaft 15 stops rotating, rotates the bolt 18. The bolt 18 drives the rotating shaft 2 8 to move to the right. The rotating shaft 2 8 is further retracted into the inside of the drive shaft 15, so that the mounting plate 11 on the right is completely disassembled. Then the staff pulls out the activated carbon filter 10 to the right. During the disassembly process, since the fixed end of the fixing head 13 is dome-shaped, the fixing head 13 will be squeezed into the inside of the protrusion 12 to complete the disassembly operation.
