Description

Technical Field

[0001] This utility model relates to the field of liquid paraffin exhaust gas treatment technology, specifically a liquid paraffin exhaust gas treatment device. Background Technology

[0002] In the chemical production field, liquid paraffin is an important basic chemical raw material. The exhaust gas generated during its production process is complex, containing various volatile organic compounds and harmful gases. Direct emission of these gases would cause serious air pollution. Currently, there are various methods for treating liquid paraffin exhaust gas, including combustion, absorption, and adsorption. While combustion can effectively decompose harmful components, it suffers from high energy consumption and the potential for secondary pollution. Absorption methods are limited by the performance of the absorbent, resulting in unstable treatment effects. Activated carbon adsorption, however, is a highly favored treatment method due to its abundant pore structure and large specific surface area, which allows it to efficiently adsorb various pollutants in the exhaust gas. Its excellent adsorption capacity and selectivity make it a preferred treatment method.

[0003] However, in practical applications, activated carbon has significant drawbacks in treating waste gas. On the one hand, activated carbon has a limited adsorption capacity, and its adsorption capacity decreases rapidly as adsorption proceeds, requiring frequent replacement to maintain the exhaust gas treatment effect. Activated carbon after absorbing waste gas becomes hazardous waste, and operators are highly susceptible to inhalation or skin contact with pollutants during direct contact, seriously threatening their health.

[0004] Therefore, it is necessary to modify it by setting up a convenient activated carbon plate replacement structure to reduce the time for activated carbon plate replacement, reduce labor costs and equipment downtime, and centrally treat the activated carbon after absorbing waste gas without direct contact with operators, thus protecting the health of operators and making it convenient for users.

Slots 6 are fixedly connected to both the front and rear sides of the inner wall of the C-shaped frame 4, and activated carbon plates 7 are attached to the inside of the slots 6. The top of the treatment box 2 is connected to an exhaust pipe 8 located between the right side of the activated carbon plate 7 and the top left side of the L-shaped plate 5. The right side of the inner wall of the treatment box 2 is fixedly connected to a first electric telescopic rod 9. The output end of the first electric telescopic rod 9 is fixedly connected to the right side of the C-shaped frame 4. The left side of the top of the treatment box 2 is provided with a replacement insertion slot 10 that runs through both the inside and outside. The top of the replacement insertion slot 10 is provided with a sealing structure 11. The top of the bottom plate 1 is provided with a carbon plate collection box 12 located below the treatment box 2. The front of the carbon plate collection box 12 is provided with a square groove, and the inside of the square groove is slidably connected with a movable sealing cover 13. The bottom of the treatment box 2 is provided with a carbon plate discharge slot 14 located on the right side above the carbon plate collection box 12.

[0022] refer to Figure 2 The sealing structure includes a removable cover plate 15 that is fixedly connected to the top left side of the processing box 2 by bolts. A sealing gasket 16 is fixedly connected to the bottom of the cover plate 15, and the surface of the sealing gasket 16 is in contact with the inner wall of the replacement insertion slot 10.

[0023] As a technical optimization of this utility model, the cover plate 15 is fixed to the top left side of the treatment box 2 by using bolts, and the sealing gasket 16 at the bottom of the cover plate 15 fits against the inner wall of the replacement insertion slot 10, which has a sealing effect on the replacement insertion slot 10, preventing exhaust gas leakage during exhaust gas treatment, further ensuring the sealing of the treatment box 2, maintaining the normal operation of the device and good exhaust gas treatment effect. At the same time, when it is necessary to replace the new activated carbon plate 7, the cover plate 15 can be opened by loosening the bolts, making it convenient to directly insert the new activated carbon plate 7 into the device.

[0024] refer to Figure 2 A second electric telescopic rod 17 is fixedly connected to the right side of the bottom of the processing box 2. The output end of the second electric telescopic rod 17 is fixedly connected to a push plate 18 located on the right side of the bottom of the carbon plate discharge trough 14. The top of the push plate 18 is slidably connected to the bottom of the processing box 2. The first electric telescopic rod 9, the second electric telescopic rod 17 and the solenoid valve are all electrically connected to the external controller.

[0025] As a technical optimization of this utility model, by setting the second electric telescopic rod 17 and push plate 18 on the bottom right side of the processing box 2, when the activated carbon plate 7 is saturated with adsorption, and it is discharged through the carbon plate discharge groove 14, the second electric telescopic rod 17 is activated to drive the push plate 18 to move to the left, which can push the activated carbon plate 7 falling from the carbon plate discharge groove 14 into the carbon plate collection box 12, thereby automating the discharge process of the activated carbon plate 7, reducing manual intervention, and improving work efficiency; at the same time, the first electric telescopic rod 9, the second electric telescopic rod 17 and the solenoid valve are all electrically connected to the external controller, which facilitates unified control and operation of the device and improves the intelligence level of the device.

[0026] refer to Figure 1 Rollers 19 are provided at the four corners of the bottom of the carbon plate collection box 12, and tracks 20 are provided on the front and rear sides of the top of the bottom plate 1. The surface of the rollers 19 is in contact with the inner wall of the track 20.

[0027] As a technical optimization of this utility model, rollers 19 are installed at the four corners of the bottom of the carbon plate collection box 12, and a track 20 is provided on the top of the base plate 1. The rollers 19 cooperate with the track 20, making it easier to move the carbon plate collection box 12. When the carbon plate collection box 12 is full of activated carbon plates 7, it can be easily removed from the track 20 for processing, improving the practicality and ease of operation of the device. At the same time, when the carbon plate collection box 12 is pushed onto the base plate 1, the rollers 19 are aligned with the track 20 to keep the carbon plate collection box 12 aligned with the carbon plate discharge groove 14, so that the waste gas carbon plates can fall accurately into the carbon plate collection box 12.

[0028] refer to Figure 3 The upper and lower sides of the front and rear sides of the inner wall of the processing box 2 are fixedly connected with the guide rail 21 with sealing effect. The upper and lower sides of the front and back of the C-shaped frame 4 are provided with the sliding groove 22 that cooperates with the guide rail 21. The surface of the guide rail 21 is slidably connected to the inner wall of the sliding groove 22.

[0029] As a technical optimization of this utility model, guide rails 21 with sealing effect are fixedly connected to the upper and lower sides of the front and rear sides of the inner wall of the treatment box 2. Slide grooves 22 that cooperate with the guide rails 21 are opened on the upper and lower sides of the front and back of the C-shaped frame 4. The sliding connection between the guide rails 21 and the slide grooves 22 not only further enhances the sealing of the treatment box 2, but also ensures the stability of the C-shaped frame 4 moving in the treatment box 2, making the first electric telescopic rod 9 push the C-shaped frame 4 more smoothly, which is conducive to the replacement operation of the activated carbon plate 7.

[0030] refer to Figure 2 The front and rear sides of the bottom left side of the inner wall of the treatment box 2 are fixedly connected to the first limiting block 23. The distance from the left side of the C-shaped frame 4 to the right side of the first limiting block 23 is the same as the distance from the activated carbon plate 7 to the replacement insertion slot 10. The front and rear sides of the bottom right side of the inner wall of the treatment box 2 are fixedly connected to the second limiting block 24. The distance from the activated carbon plate 7 to the carbon plate discharge slot 14 is the same as the distance from the right side of the C-shaped frame 4 to the left side of the second limiting block 24.

[0031] As a technical optimization of this utility model, the first limiting block 23 and the second limiting block 24 play a positioning role. The first limiting block 23 can move the C-shaped frame 4 to a suitable position to ensure that the activated carbon plate 7 is aligned with the replacement insertion slot 10, which facilitates the insertion of the new activated carbon plate 7. The second limiting block 24 can move the C-shaped frame 4 to a suitable position to ensure that the activated carbon plate 7 is aligned with the carbon plate discharge slot 14, which facilitates the smooth discharge of the used activated carbon plate 7 into the carbon plate collection box 12, thereby improving the accuracy and efficiency of the activated carbon plate 7 replacement and discharge process.

[0032] The working principle and usage process of this utility model are as follows: When in use, the air inlet pipe 3 is connected to the exhaust gas outlet pipe. The solenoid valve is opened by the external controller, allowing the exhaust gas to enter the treatment box 2. At this time, the exhaust gas will pass through the activated carbon plate 7 in the C-shaped frame 4. The activated carbon plate 7 begins to adsorb pollutants in the exhaust gas. The exhaust gas continues to enter the treatment box 2 from the air inlet pipe 3. After being adsorbed by the activated carbon plate 7 in the treatment box 2, the purified exhaust gas is discharged from the exhaust pipe 8. As time goes by, the adsorption capacity of the activated carbon plate 7 gradually decreases. At this point, the activated carbon plate 7 needs to be replaced according to the actual situation or a preset time interval. The operator closes the solenoid valve through the external controller to stop the exhaust gas from entering the treatment box 2, and starts the first electric telescopic rod 9, which retracts to pull the C-shaped frame 4 to the right. When the C-shaped frame 4 moves to the appropriate position, aligning the activated carbon plate 7 with the carbon plate discharge groove 14, the used activated carbon plate 7 will fall from the carbon plate discharge groove 14. At the same time, the second electric telescopic rod 17 is started, which pushes the push plate 18 to push the fallen activated carbon plate 7 into the carbon plate collection box 12. Then, the first electric telescopic rod 9 is extended, causing the C-shaped frame 4 to move to the left, aligning the slot 6 inside the C-shaped plate with the replacement insertion slot 10. The top of the treatment box 2 is then opened for replacement. The sealing structure 11 of the insertion slot 10 has a detachable cover 15. A new activated carbon plate 7 is inserted into the slot 6 of the C-shaped frame 4 through the replacement insertion slot 10. After insertion, the sealing structure 11 is closed to ensure the airtightness of the treatment box 2. The first electric telescopic rod 9 is then activated again to move the C-shaped frame 4 to its initial position, allowing the new activated carbon plate 7 to begin adsorbing the exhaust gas. When the carbon plate collection box 12 is full of used activated carbon plates 7, the operator can easily remove the carbon plate collection box 12 via the track 20 for centralized disposal of the activated carbon after absorbing the exhaust gas. Furthermore, after replacing or removing the carbon plates, the movable sealing cover 13 can be pushed backward to close the top of the carbon plate collection box 12, preventing the carbon plates from emitting harmful substances.
