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.

[0022] Example 1

[0023] Please see Figures 1-5 This utility model provides the following technical solution: an activated carbon adsorption-desorption circulation device, including a housing 1, a pipe 2 installed on one side of the housing 1, a dry filter 3 installed at the other end of the pipe 2, a VOCs input pipe 4 installed at the other end of the dry filter 3, a first electric valve 5 installed on the side of the pipe 2, an air outlet pipe 8 installed on the other side of the housing 1, a second electric valve 16 installed on the side of the air outlet pipe 8, a rain shield 10 installed at the upper end of the air outlet pipe 8, a partition 19 fixedly connected inside the housing 1, a drain pipe 14 fixedly connected to the lower side of the partition 19, and a third electric valve 13 installed on the side of the drain pipe 14. A water outlet pipe 12 is provided on the lower side of the body 1. A PLC control cabinet 11 is fixed to the lower center of the body 1 by screws. An activated carbon plate body 7 is slidably connected inside the body 1. A connecting housing 17 is fixedly connected to the upper end of the partition 19 inside the body 1. A desorption fan 15 is provided at the lower end of the connecting housing 17. A catalyst box 18 is provided at the upper end of the partition 19 near the connecting housing 17. A nozzle 20 corresponding to the activated carbon plate body 7 is provided at the lower end of the catalyst box 18. The activated carbon plate body 7 and the body 1 are fixedly connected by an activated carbon plate fixing mechanism 6. A dustproof plate fixing mechanism 9 is provided at the upper end of the connecting housing 17.

[0024] Specifically, the dustproof panel fixing mechanism 9 includes a locking block 91, a fixing hole 92, a locking groove 93, a fixing component 94, and a dustproof panel body 95. The dustproof panel body 95 is installed on the upper end of the connecting housing 17. The locking block 91 is provided on the side of the dustproof panel body 95, and the locking hole 92 is opened on the side of the locking block 91. The locking groove 93 corresponding to the locking block 91 is opened on the upper side of the connecting housing 17. The fixing component 94 is provided on the upper end of the housing 1 near the locking groove 93.

[0025] By adopting the above technical solution, when installing the dustproof panel body 95, the clip 91 on the side of the dustproof panel body 95 is inserted into the slot 93, and then the fixing component 94 and fixing hole 92 are used to fix the dustproof panel body 95.

[0026] Specifically, the fixing component 94 includes a fixing rod 941, a sliding rod 942, an L-shaped mounting groove 943, and a sliding plate 945. An L-shaped mounting groove 943 is provided at the upper end of the housing 1 near the slot 93. The sliding plate 945 is slidably connected inside the L-shaped mounting groove 943. The fixing rod 941 is fixedly connected to one side of the sliding plate 945, and the sliding rod 942 is slidably connected to the other side of the sliding plate 945.

[0027] By adopting the above technical solution, when installing the dustproof panel body 95, the sliding plate 945 in the sliding L-shaped mounting groove 943 slides on the surface of the sliding rod 942, and drives the spring 944 to compress. At this time, the locking block 91 on the side of the dustproof panel body 95 is inserted into the slot 93. Then, the sliding plate 945 is released, the spring 944 rebounds, thereby driving the fixing rod 941 to be inserted into the fixing hole 92, thus fixing the dustproof panel body 95.

[0028] Specifically, a spring 944 is fitted onto the surface of the slide bar 942 on one side of the slide plate 945.

[0030] In this embodiment, during installation of the dustproof panel body 95, the sliding plate 945 in the L-shaped mounting groove 943 slides on the surface of the sliding rod 942, compressing the spring 944. Then, the locking block 91 on the side of the dustproof panel body 95 is inserted into the slot 93. Releasing the sliding plate 945 causes the spring 944 to rebound, thus inserting the fixing rod 941 into the fixing hole 92, securing the dustproof panel body 95. Similarly, sliding the sliding plate 945 again allows the fixing rod 941 to slide out of the fixing hole 92, enabling the dustproof panel body 95 to be disassembled for cleaning of the dustproof panel body 95 and the desorption fan 15. During VOCs adsorption and desorption, the process is controlled by a PLC. Cabinet 11 opens the first electric valve 5 for a set time. VOCs are first initially filtered by the dry filter 3, and then adsorbed by the activated carbon plate body 7. Then the first electric valve 5 is closed. After a set time, when the VOCs are saturated by the activated carbon plate body 7, the desorption fan 15 is turned on. After a set time, the desorption is completed. At the same time, the second electric valve 16 and the nozzle 20 at the lower end of the catalyst box 18 are opened, so that the nozzle 20 sprays out the catalyst, which reacts with the desorbed substances to produce carbon dioxide and water. The third electric valve 13 is opened, and the water flows out through the drain pipe 14 and is discharged through the water outlet pipe 12. The carbon dioxide is discharged into the atmosphere. Then the first electric valve 5, the second electric valve 16 and the third electric valve 13 are reset for the next cycle.

[0031] Example 2

[0032] The difference between this embodiment and Embodiment 1 is that the activated carbon plate fixing mechanism 6 includes a fixing component 61, a slot 62, a card holder 63, an insert 64, a card hole 65, and a connecting plate 66. The connecting plate 66 is fixedly connected to the side of the activated carbon plate body 7. The insert 64 is provided on the side of the connecting plate 66. Card holes 65 are opened at both the upper and lower ends of the insert 64. The card holder 63 is installed at the side edge of the box body 1. The slot 62 corresponding to the insert 64 is opened on the side of the card holder 63. The fixing component 61 is provided inside the side of the card holder 63.

[0033] By adopting the above technical solution, when disassembling the activated carbon plate body 7, by pulling the activated carbon plate body 7, the activated carbon plate body 7 drives the connecting plate 66 to slide outward. The connecting plate 66 slides outward and drives the insert 64 to slide out of the slot 62 in the card holder 63. At this time, the activated carbon plate body 7 can be disassembled and replaced.

[0034] Specifically, the fixing component 61 includes a second spring 611, a limiting plate 612, and a locking pin 613. The second spring 611 is disposed inside the side of the mounting base 63. The other end of the second spring 611 is provided with the limiting plate 612, and the other end of the limiting plate 612 is provided with the locking pin 613. The other end of the locking pin 613 is configured with an arc-shaped structure.

[0035] By adopting the above technical solution, when fixing the activated carbon plate body 7, the insert 64 on the side of the connecting plate 66 is inserted into the slot 62 again. By setting the other end of the locking pin 613 into an arc-shaped structure, the insert 64 squeezes the locking pin 613. After the locking pin 613 is squeezed, it will compress the limiting plate 612 and the second spring 611. When the locking hole 65 is aligned with the locking pin 613, the second spring 611 rebounds, thereby driving the locking pin 613 to be inserted into the locking hole 65, so as to fix the activated carbon plate body 7.

[0036] In this embodiment, when disassembling the activated carbon plate body 7, by pulling the activated carbon plate body 7, the activated carbon plate body 7 drives the connecting plate 66 to slide outward. The sliding of the connecting plate 66 causes the insert 64 to slide out of the slot 62 in the card holder 63. At this time, the activated carbon plate body 7 can be disassembled and replaced. When fixing the activated carbon plate body 7, the insert 64 on the side of the connecting plate 66 is inserted into the slot 62 again. By setting the other end of the locking pin 613 into an arc structure, the insert 64 squeezes the locking pin 613. After the locking pin 613 is squeezed, it will compress the limiting plate 612 and the second spring 611. When the card hole 65 is aligned with the locking pin 613, the second spring 611 rebounds, thereby driving the locking pin 613 to be inserted into the card hole 65, so as to fix the activated carbon plate body 7.

[0037] The structure and operating principle of the dry filter 3, first electric valve 5, PLC control cabinet 11, third electric valve 13, desorption fan 15, second electric valve 16, catalyst box 18, and nozzle 20 in this utility model have been disclosed in Chinese patent application No. 202420670788.6, which discloses an activated carbon adsorption-desorption circulation device. Its working principle involves the PLC control cabinet 11 opening the first electric valve 5 for a set time. VOCs are first initially filtered by the dry filter 3, then adsorbed by the activated carbon plate body 7, and finally the first electric valve 5 is closed. After a set time, once the VOCs are saturated by the activated carbon plate body 7, the desorption fan 15 is turned on. After a set working time, the desorption is completed, and at the same time, the second electric valve 16 and the nozzle 20 at the lower end of the catalyst box 18 are opened, so that the nozzle 20 sprays out the catalyst, which reacts with the desorbed substances to produce carbon dioxide and water. The third electric valve 13 is opened, and the water flows out along the drain pipe 14 and is discharged through the water outlet pipe 12. The carbon dioxide is discharged into the atmosphere. Then the first electric valve 5, the second electric valve 16 and the third electric valve 13 are reset, and the next cycle treatment is carried out.

[0038] The working principle and usage process of this utility model are as follows: When installing the dustproof plate body 95, the sliding plate 945 in the L-shaped mounting groove 943 slides on the surface of the sliding rod 942, compressing the spring 944. Then, the locking block 91 on the side of the dustproof plate body 95 is inserted into the slot 93. Releasing the sliding plate 945 causes the spring 944 to rebound, thus inserting the fixing rod 941 into the fixing hole 92, thereby fixing the dustproof plate body 95. Similarly, by sliding the sliding plate 945 again, the fixing rod can be inserted into the fixing hole 92. 941 slides out from inside the fixing hole 92, allowing the dustproof plate body 95 to be disassembled for cleaning of the dustproof plate body 95 and the desorption fan 15. During VOCs adsorption and desorption, the first electric valve 5 is opened for a set time via the PLC control cabinet 11. VOCs are first pre-filtered by the dry filter 3, then adsorbed by the activated carbon plate body 7. The first electric valve 5 is then closed. After a set time, once the activated carbon plate body 7 is saturated with VOCs, the desorption fan 15 is turned on. After a set working time, desorption is complete, and simultaneously... Open the second electric valve 16 and the nozzle 20 at the lower end of the catalyst tank 18, causing the nozzle 20 to spray the catalyst, which reacts with the desorbed substances to produce carbon dioxide and water. The third electric valve 13 opens, and the water flows out through the drain pipe 14 and is discharged through the water outlet pipe 12, while the carbon dioxide is released into the atmosphere. Then, the first electric valve 5, the second electric valve 16, and the third electric valve 13 are reset for the next cycle. When disassembling the activated carbon plate body 7, by pulling the activated carbon plate body 7, the activated carbon plate body 7 drives the connecting plate 66 to slide outward, and the connecting plate 66 sliding outward drives the insert block 64. Slide the activated carbon plate body 7 out of the slot 62 in the card holder 63. At this time, the activated carbon plate body 7 can be disassembled and replaced. When fixing the activated carbon plate body 7, insert the insert block 64 on the side of the connecting plate 66 into the slot 62 again. By setting the other end of the locking pin 613 into an arc structure, the insert block 64 presses the locking pin 613. After the locking pin 613 is pressed, it will compress the limiting plate 612 and the second spring 611. When the card hole 65 is aligned with the locking pin 613, the second spring 611 rebounds, thereby driving the locking pin 613 to be inserted into the card hole 65 to fix the activated carbon plate body 7.
