Description

Technical Field

[0001] This utility model relates to the field of VOCs treatment technology, specifically a two-stage activated carbon VOCs adsorption device. Background Technology

[0002] VOCs (volatile organic compounds) refer to organic compounds with a saturated vapor pressure greater than 70 Pa at room temperature and a boiling point below 260℃ at normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10 Pa at 20℃ that exhibit corresponding volatility. High concentrations of VOCs in the air can easily cause acute poisoning. Mild cases may present with headache, dizziness, cough, nausea, vomiting, or a state of intoxication; severe cases may lead to liver poisoning and even rapid coma, and in some cases, may be life-threatening.

[0003] Using activated carbon to adsorb VOCs is an effective waste gas treatment technology. However, if the waste gas contains large particulate matter, it will affect the adsorption effect of activated carbon on VOCs. Therefore, a two-stage activated carbon adsorption is adopted. The first stage is mainly used to adsorb large particulate matter in the waste gas, and the second stage is mainly used to adsorb VOCs in the waste gas. This can effectively purify VOCs in the waste gas. However, after adopting a two-stage activated carbon adsorption, the replacement of activated carbon is more troublesome and inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a two-stage activated carbon VOCs adsorption device to solve the problems mentioned in the background art.

[0006] The transposition assembly includes an electric rotary table, a rotating rod mounted on the top of the rotating part of the electric rotary table, and a horizontal plate fixed to the top of the rotating rod.

[0007] The telescopic assembly includes a housing, a baffle slidably connected to the inner wall of the housing, and a compression spring disposed inside the housing.

[0008] A through hole is opened in the middle of the outer wall of the top of the disk, and the rotating rod passes through the through hole.

[0009] The top outer wall of the baffle is in contact with the bottom outer wall of the storage tube, and the top outer walls of the first and second tubes are at the same height as the bottom outer wall of the storage tube.

[0010] An observation port is provided on one side of the outer wall of the storage tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention relates to a two-stage activated carbon VOCs adsorption device, which can perform two-stage purification of waste gas. The first-stage adsorption mainly removes large particulate matter from the waste gas, while the second-stage adsorption mainly removes VOCs. This results in the activated carbon adsorption blocks in the first-stage adsorption being more saturated than those in the second-stage adsorption within the same working time. By rotating the transfer component, the activated carbon adsorption blocks in the second-stage adsorption are automatically moved to the first-stage adsorption for reuse. At the same time, the activated carbon adsorption blocks used for the second-stage adsorption are automatically replaced during the rotation process. The device eliminates the need for manual replacement of the activated carbon adsorption blocks, making it more convenient. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a two-stage activated carbon VOCs adsorption device, comprising: a base plate 1, and an inlet pipe 2 and an outlet pipe 3 respectively fixed to the two ends of the top outer wall of the base plate 1. The outer walls of the inlet pipe 2 and the outlet pipe 3 are fitted with the same disc 4, and a displacement component 5 is installed in the middle of the top outer wall of the base plate 1. The two ends of the displacement component 5 are respectively fitted with a first pipe 6 and a second pipe 7. An extension plate 8 is installed on one side of the outer wall of the disc 4. Telescopic components 11 are installed at both ends of one side of the outer wall of the extension plate 8. A fixing plate 9 is installed on the top outer wall of the extension plate 8. A storage pipe 10 is installed at one end of the fixing plate 9. A fixing frame 12 is installed on the outer wall of the storage pipe 10. A bent pipe 13 is installed at one end of the fixing frame 12. A support net 14 is installed on the inner wall of the top opening of the inlet pipe 2 and the outlet pipe 3. Activated carbon adsorption blocks 15 are placed in the first pipe 6, the second pipe 7 and the storage pipe 10. A discharge port 16 is opened at one end of the top outer wall of the disc 4.

[0022] It should be noted that: exhaust gas can enter through inlet pipe 2. After primary adsorption and purification by activated carbon adsorption block 15 in the first pipe 6, mainly removing large particulate matter, the exhaust gas enters the second pipe 7 through bend pipe 13. The activated carbon adsorption block 15 in the second pipe 7 further adsorbs and purifies the exhaust gas, mainly removing VOCs. As the gas is continuously purified, the adsorption capacity of activated carbon adsorption block 15 will gradually decrease, requiring periodic replacement. Since the activated carbon adsorption block 15 in the first pipe 6 performs primary adsorption and filtration, its adsorption saturation level is higher than that in the second pipe 7 within the same working time. Therefore, when replacing the activated carbon adsorption block 15, the first pipe 6 and the second pipe 7 can be rotated and repositioned by the switching component 5, thereby removing VOCs from the second pipe 7. The activated carbon adsorption block 15 is transferred to the top of the inlet pipe 2, where it can continue to adsorb large particulate matter in the waste gas, achieving a secondary utilization function. The activated carbon adsorption block 15 in the first pipe 6 falls from the top of the discharge port 16 as the first pipe 6 rotates. When the first pipe 6 rotates to the bottom of the storage pipe 10, the first pipe 6 squeezes the two telescopic components 11, causing the two telescopic components 11 to retract and move away from the bottom of the storage pipe 10. At this time, the unused activated carbon adsorption block 15 stored in the storage pipe 10 automatically falls down. The activated carbon adsorption block 15 at the bottom falls into the first pipe 6 and is moved to the top of the outlet pipe 3 as the first pipe 6 rotates, where it can be used to adsorb VOCs in the waste gas after primary treatment. As the first pipe 6 moves away from the bottom of the storage pipe 10, the two telescopic components 11 automatically reset and block the bottom of the storage pipe 10, preventing the activated carbon adsorption block 15 in the storage pipe 10 from continuing to fall. The device does not require manual replacement of the activated carbon adsorption block 15, making it more convenient.

[0023] In a preferred embodiment, the transposition assembly 5 includes an electric rotary table 501, a rotating rod 502 mounted on the top of the rotating part of the electric rotary table 501, and a horizontal plate 503 fixed to the top of the rotating rod 502.

[0024] It should be noted that the electric rotary table 501 can drive the rotating rod 502 to rotate, which in turn drives the horizontal plate 503 to rotate, which in turn drives the first tube 6 and the second tube 7 to rotate and change position.

[0025] In a preferred embodiment, the telescopic assembly 11 includes a housing 1101, a baffle 1102 slidably connected to the inner wall of the housing 1101, and a compression spring 1103 disposed inside the housing 1101.

[0026] It should be noted that when the first tube 6 rotates to below the storage tube 10, it will push the baffle 1102 into the housing 1101 and compress the compression spring 1103. When the first tube 6 rotates away, the compression spring 1103 will push the baffle 1102 outward to reset.

[0027] In a preferred embodiment, a through hole is provided in the middle of the outer wall of the top of the disk 4, and the rotating rod 502 passes through the through hole.

[0028] It should be noted here that: disk 4 does not affect the rotation of rotating rod 502.

[0029] In a preferred embodiment, the top outer wall of the baffle 1102 is in contact with the bottom outer wall of the storage tube 10, and the top outer walls of the first tube 6 and the second tube 7 are at the same height as the bottom outer wall of the storage tube 10.

[0030] It should be noted that during the rotation of the first tube 6, it can fit against the bottom outer wall of the storage tube 10, which facilitates the activated carbon adsorption block 15 in the storage tube 10 falling into the first tube 6.

[0031] In a preferred embodiment, an observation port is provided on one side of the outer wall of the storage tube 10.

[0032] It should be noted here that this is to facilitate observation of the number of activated carbon adsorption blocks 15 stacked in storage tube 10, so as to replenish them in a timely manner.

[0033] Working principle: Waste gas can enter through the inlet pipe 2. After the waste gas is purified by the activated carbon adsorption block 15 in the first pipe 6, the large particulate matter in the waste gas is mainly removed. After primary treatment, the waste gas enters the second pipe 7 through the bend pipe 13. The activated carbon adsorption block 15 in the second pipe 7 further adsorbs and purifies the waste gas, mainly removing VOCs. As the gas is continuously purified, the adsorption capacity of the activated carbon adsorption block 15 will gradually decrease. At this time, it is necessary to replace the activated carbon adsorption block 15 regularly. Since the activated carbon adsorption block 15 in the first pipe 6 performs primary adsorption and filtration of the gas, the adsorption saturation of the activated carbon adsorption block 15 in the first pipe 6 is greater than that of the activated carbon adsorption block 15 in the second pipe 7 within the same working time.

[0034] Therefore, when replacing the activated carbon adsorption block 15, the electric rotary table 501 can drive the rotating rod 502 to rotate, which in turn drives the horizontal plate 503 to rotate, thereby causing the first tube 6 and the second tube 7 to rotate and change positions. This transfers the activated carbon adsorption block 15 in the second tube 7 to the top of the air inlet pipe 2, where it can continue to adsorb large particles in the waste gas, achieving a secondary utilization function. The activated carbon adsorption block 15 in the first tube 6 falls from above the discharge port 16 as the first tube 6 rotates. When the first tube 6 rotates to the bottom of the storage tube 10, it pushes the two baffles 1102 into the two housings 1101 respectively and squeezes the two compression springs 110. 3. This causes the two baffles 1102 to move away from the bottom of the storage tube 10. At this time, the unused activated carbon adsorption blocks 15 stored in the storage tube 10 automatically fall down. The activated carbon adsorption block 15 at the bottom falls into the first tube 6. As the first tube 6 rotates, it is moved above the outlet tube 3 and can be used to adsorb VOCs in the exhaust gas after primary treatment. During the process of the first tube 6 moving away from below the storage tube 10, the two compression springs 1103 push the two baffles 1102 outward and reset them, continuing to block below the storage tube 10 to prevent the activated carbon adsorption blocks 15 in the storage tube 10 from falling further. The device does not require manual replacement of the activated carbon adsorption blocks 15, which is more convenient.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
