Description

Technical Field

[0001] The utility model relates to the technical field of adsorption devices, in particular to an activated carbon adsorption device for waste gas. Background Art

[0002] Activated carbon adsorption device for waste gas is a common waste gas treatment technology. Activated carbon is a porous carbon material with extremely high specific surface area and rich microporous structure. This porous structure gives activated carbon excellent adsorption capacity, enabling it to efficiently adsorb pollutants such as organic matter, gas and pigments in gases, liquids and solutions. Activated carbon adsorption devices are widely used in various industrial fields, such as chemical industry, coating, printing, and environmental protection fields, such as air pollution control and water treatment. In the field of environmental protection, activated carbon adsorption devices are used to remove volatile organic compounds in waste gas to meet environmental emission standards. As the activated carbon adsorption is saturated, it needs to be regenerated or replaced. Common regeneration methods include heating, steam purging, nitrogen flushing, etc. Through regeneration, the adsorbed organic matter can be released, so that the activated carbon can be restored to a state where it can be used again.

[0003] When existing waste gas activated carbon adsorption devices are performing waste gas adsorption operations, it is often necessary to set different amounts of activated carbon for waste gases with different emission amounts to meet the adsorption needs. However, the existing waste gas activated carbon adsorption devices are not convenient for adjusting the amount of activated carbon, and are inconvenient to use. During actual adsorption, the activated carbon close to the air inlet end is often scrapped first, while the activated carbon far from the air inlet end has not yet reached the scrap standard. It is wasteful to directly replace the activated carbon far from the air inlet end, and the maximum utilization rate of the activated carbon cannot be achieved. The existing waste gas activated carbon adsorption devices are not convenient for replacing activated carbon, which affects work efficiency.

[0004] Therefore, an activated carbon adsorption device for waste gas is proposed. Utility Model Content

The second hydraulic cylinder 40 controls the extension of the second telescopic rod 41 to make the lower fixed second universal wheel 42 extend out of the second groove 39, and the second universal wheel 42 can move in different directions, so that the sealing mechanism 3 can be moved and fixed more easily.

[0030] like Figure 1-Figure 8As shown, a plurality of filter devices 13 are installed between the two sealing mechanisms 3, the plurality of filter devices 13 have the same structure, and the plurality of filter devices 13 abut against each other, the filter devices 13 each include a housing 14, and the outer sides of the housings 14 of the two outermost filter devices 13 abut against the corresponding sealing pipes 9, screw holes 15 are provided on both sides of the upper and lower ends of the housing 14, and the plurality of screw holes 15 are threadedly connected with screws 12, and a first fixing sheet 11 is provided between the upper and lower ends of adjacent housings 14, and the adjacent screws 12 between the two housings 14 penetrate the first fixing sheet 11 and are fixed to the upper and lower ends of the housing 14, and the screws on the outer sides of the housings 14 at both ends are fixed to the upper and lower ends of the housings 14.

[0031] like Figure 5-Figure 6 As shown, a sealing box 16 is movably sleeved in the shell 14, a sealing strip 17 is fixedly installed on one side of the sealing box 16, and the sealing strip 17 is sleeved in the sealing pipe 9. Two hinges 20 are fixedly installed on one side of the sealing box 16, and a sealing door 21 is fixedly installed on one side of the two hinges 20. A second handle 22 is fixedly installed on the sealing door 21. An activated carbon box 19 is movably arranged in the sealing box 16, and a first handle 18 is fixedly installed on one side of the activated carbon box 19. Second brackets 37 are fixedly installed at the four corners of the lower end of the shell 14, and the four second brackets 37 are fixedly installed with first universal wheels 38. By adopting the above technical solution, the second handle 22 is pulled to drive the sealing door 21, and the sealing door 21 can be opened by the hinge 20 connected between the sealing door 21 and the sealing box 16. The first universal wheel 38 arranged below the shell 14 can move the components on the second bracket 37 to different directions on all sides, which can be more convenient during installation and disassembly.

[0032] like Figure 7-Figure 9As shown, first grooves 23 are provided at both upper and lower ends of the shell 14, springs 24 are fixedly installed at one end of the two first grooves 23, and plug-in blocks 25 are fixedly installed at one end of the two springs 24. Abutment grooves 26 are provided at both upper and lower ends of the sealing box 16 and correspond to the plug-in blocks 25. The plug-in blocks 25 can be plugged into the abutment grooves 26. By adopting the above technical solution, when the sealing mechanism 3 pushes the sealing box 16, the plug-in block 25 can be squeezed to drive the spring 24 to contract and squeeze the plug-in block 25 into the first groove 23. When the first groove 23 of the next sealing box 16 is pushed to the plug-in block 25 by the sealing mechanism 3, the spring 24 can reinsert the plug-in block 25 into the abutment groove 26.

[0033] like Figure 1-Figure 2 As shown, one side of the cavity 4 of a sealing mechanism 3 is fixedly connected to a first air inlet pipe 27, a hot air blower 29 is fixedly installed on the upper end of the first air inlet pipe 27, the output end of the hot air blower 29 is connected to the first air inlet pipe 27, a dust filter 30 is fixedly installed on the end of the first air inlet pipe 27 away from the cavity 4, and an air inlet valve 28 is fixedly installed inside the first air inlet pipe 27 between the hot air blower 29 and the dust filter 30. By adopting the above-mentioned technical scheme, closing the air inlet valve 28 can stop the first air inlet pipe 27 from outputting exhaust gas. When the first air inlet pipe 27 stops conveying exhaust gas, controlling the hot air blower 29 to start can convey hot air into the first air inlet pipe 27, thereby achieving the effect of desorption of the activated carbon box 19 in the filter device 13.

[0034] like Figure 1-Figure 2 As shown, a first exhaust pipe 31 is fixedly installed on one side of the cavity 4 of another sealing mechanism 3, an exhaust valve 32 is fixedly installed in the first exhaust pipe 31, a second air inlet pipe 33 is fixedly connected to one side of the first exhaust pipe 31, an incinerator 35 is fixedly installed on one end of the second air inlet pipe 33, the second air inlet pipe 33 is communicated with the incinerator 35, a second exhaust pipe 34 is fixedly connected to one side of the incinerator 35, and one end of the second exhaust pipe 34 is fixedly connected to one side of the first exhaust pipe 31. By adopting the above technical solution, closing the exhaust valve 32 can stop the first exhaust pipe 31 from transporting exhaust gas to the outside, and starting the incinerator 35 can allow the desorbed exhaust gas to enter the incinerator 35 along the second air inlet pipe 33 for incineration, and the incinerated exhaust gas is then discharged to the first exhaust pipe 31 through the second exhaust pipe 34.

[0035] like Figure 1-Figure 4 As shown, a control panel 2 is fixedly mounted on the first bracket 1 , and an output end of the control panel 2 is electrically connected to an input end of the first hydraulic cylinder 6 , a first air inlet pipe 27 , a hot air blower 29 , an incinerator 35 , and a second hydraulic cylinder 40 .

[0036] It should be noted that the utility model is an activated carbon adsorption device for waste gas. When in use, firstly, four first brackets 1 are installed at designated positions, and the first hydraulic cylinder 6 on the first fixed block 5 connected to the two sealing mechanisms 3 is started through the control panel 2, so that the first telescopic rod 7 drives the sealing pipe 9 connected to the second fixed block 8, so that the sealing pipes 9 of the two sealing mechanisms 3 clamp the filter device 13, and then the air inlet valve 28 and the air outlet valve 32 are opened, and the waste gas to be filtered will enter the dust filter 30 to initially filter out the dust particles, and then the waste gas will enter the cavity 4 of the sealing mechanism 3 along the first air inlet pipe 27. When the waste gas passes through the filter device 13, the activated carbon in the activated carbon box 19 in the filter device 13 will adsorb the harmful substances in the waste gas. After the waste gas passes through several filter devices 13 and reaches the designated emission standard, it will be discharged to the outside along the first exhaust pipe 31.

[0037] After the activated carbon is saturated with adsorption, it will need to be desorbed. The air inlet valve 28 and the air outlet valve 32 are closed, and the hot air blower 29 and the incinerator 35 are turned on through the control panel 2. The hot air blower 29 will send hot air into the cavity 4 along the first air inlet pipe 27. When the hot air contacts the filter device 13, the distance between the molecules of the activated carbon in the activated carbon box 19 will increase due to the heat, so as to achieve the effect of desorption. The desorbed waste gas will enter the incinerator 35 along the second air inlet pipe 33 for incineration and degradation. After the incineration is completed, it will be discharged into the first exhaust pipe 31 through the second exhaust pipe 34 and then discharged to the outside;

[0038] When the number of filter devices 13 needs to be adjusted according to usage requirements, the first hydraulic cylinder 6 is controlled to retract the first telescopic rods 7 on the two sealing mechanisms 3, driving the sealing pipe 9 connected to the second fixing block 8 to be retracted into the cavity 4, and the screws 12 connected to the second fixing plate 36 near one end of the first exhaust pipe 31 are removed. The second telescopic rod 41 is extended by controlling the second hydraulic cylinder 40 to extend the second universal wheel 42 below out of the second groove 39. The operator adjusts the installation distance of the two sealing mechanisms 3 to a suitable position, and a new filter device 13 is installed on the filter device 13 near one end of the first exhaust pipe 31. The two new first fixing plates 11 are fixed to the outer screw holes 15 at both ends of the original shell 14 by screws 12, and the other side of the first fixing plate 11 is fixed to the screw holes 15 on one side of the shell 14 at both ends of the newly installed filter device 13. Finally, the second fixing plate 36 is connected to the newly installed shell 14 by screws 12, so as to increase the number of filter devices 13 to meet different usage requirements.

[0039] When the sealing box 16 needs to be replaced, the sealing strip 17 on the replaced sealing box 16 is inserted into the right sealing pipe 9, and the first hydraulic cylinder 6 fixed on the first fixing block 5 makes the first telescopic rod 7 push the second fixing block 8 to drive the sealing pipe 9 to move forward and backward, thereby pushing the sealing box 16 in the filter device 13 to move leftward. When the sealing pipe 9 pushes the sealing box 16, the plug-in block 25 can be squeezed, thereby driving the spring 24 to contract and squeeze the plug-in block 25 into the first groove 23. When the first groove 23 of the next sealing box 16 is pushed to the plug-in block 25 by the sealing mechanism 3, the spring 24 can re-insert the plug-in block 25 into the abutment groove 26, and so on. At this time, the sealing box 16 whose iodine value close to the first air inlet pipe 27 reaches the scrap rate will move to the fixing plate 10 in the direction of the first air inlet pipe 27, and can be directly taken out through the second handle 22. By giving priority to replacing the activated carbon with lower adsorption capacity, the utilization rate of the activated carbon can be increased.

[0040] When replacing the activated carbon box 19 in the replaced sealed box 16, open the sealed door 21 and pull the sealed door 21 open through the second handle 22, pull the first handle 18 to pull out the activated carbon box 19 with too low iodine value, put the new activated carbon box 19 into the sealed box 16, and close the sealed door 21 for the next replacement.
