[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown in the figure, the exhaust gas treatment system of the natural gas drying line with energy recovery provided in this embodiment of the utility model includes a base plate 1. A combustion barrel 2 and a filter box 3 are installed on the upper side of the base plate 1. The combustion barrel 2 and the filter box 3 are connected. A filter plate 4 is installed in the middle of the filter box 3. Two slots 5 are opened on the opposite inner sides of the filter box 3. A sliding groove 6 connected to the slots 5 is opened in the middle of the opposite sides of the filter box 3. A sliding plate 7 is slidably fitted in the two sliding grooves 6. Multiple teeth 8 are installed on the opposite inner sides of the four slots 5. Two cleaning brushes 9 corresponding to the filter plate 4 are rotatably fitted between the two sliding plates 7. Gears 10 that mesh with the multiple teeth 8 are installed at both ends of the two cleaning brushes 9. A discharge port 11 is opened on the lower side of the filter box 3, and a baffle 12 corresponding to the filter plate 4 is slidably fitted on the inner side of the discharge port 11.

[0027] In this embodiment, a base plate 1 is included, and a combustion barrel 2 and a filter box 3 are installed on the upper side of the base plate 1. The combustion barrel 2 and the filter box 3 are connected, and a filter plate 4 is installed in the middle of the filter box 3.

[0028] Specifically, exhaust ports are provided on both sides of the filter box 3. Valves are provided inside the air inlet, air outlet and the two exhaust ports. A transmission pipe 21 is connected between the air outlet and one of its exhaust ports.

[0029] Specifically, an air pipe 22 is installed at the air inlet and another exhaust outlet, and multiple combustion pipes 20 are located between the air inlet and the exhaust outlet. Activated carbon filter plates are installed in both the transmission pipe 21 and one of the air pipes 22. Through the two activated carbon filter plates, the exhaust gas after combustion can be filtered and purified again, and the flue gas and harmful gases can be adsorbed.

[0030] In this embodiment, two slots 5 are opened on the inner side of the filter box 3, and a sliding groove 6 connected to the slot 5 is opened in the middle of the opposite sides of the filter box 3. A sliding plate 7 is slidably fitted in the two sliding grooves 6. Multiple teeth 8 are installed on the inner side of the four slots 5. Two cleaning brushes 9 corresponding to the filter plate 4 are rotatably fitted between the two sliding plates 7.

[0031] Specifically, a first screw 13 is rotatably fitted inside one of the slide grooves 6. The periphery of the first screw 13 is threadedly fitted to the middle of one of the slide plates 7. Rubber blocks 14 are elastically fitted to the opposite inner sides of the two slide grooves 6. The first screw 13 is threadedly fitted to the middle of one of the slide plates 7, thereby driving the slide plate 7 to move up and down. This causes the slide plate 7 to drive the two cleaning brushes 9 to move up and down synchronously, thus preparing for the next step of cleaning the filter plate 4.

[0032] Specifically, a support rod 15 is installed in another slide 6, and another slide plate 7 is slidably fitted on the periphery of the support rod 15. Two adjacent rubber blocks 14 are in contact with the periphery of the slide plate 7. By setting multiple rubber blocks 14, the two adjacent rubber blocks 14 are always in contact with the periphery of the slide plate 7, which can reduce the leakage of combustion gas through the two slides 6, thereby achieving a seal on the two slides 6.

[0033] In this embodiment, both ends of the two cleaning brushes 9 are equipped with gears 10 that mesh with multiple teeth 8, and the filter box 3 has a discharge port 11 on the lower side, and the inner side of the discharge port 11 is slidably fitted with a baffle 12 corresponding to the filter plate 4.

[0034] Specifically, a second screw 16 is rotatably fitted inside the lower side of the filter box 3. The output end of the second screw 16 is fixed to the periphery of the baffle 12. Motors 17 are installed on the upper side and one side of the filter box 3. The second screw 16 is threadedly fitted to the baffle 12, thereby driving the baffle 12 to move horizontally. This can open or close the discharge port 11, preparing for the next step of guiding the cleaned harmful particles into the collection box 19 for collection and storage.

[0035] Specifically, the output end of one motor 17 is fixed to the upper end of the first screw 13, the output end of the other motor 17 is fixed to one end of the second screw 16, and a fuel tank 18 and a collection box 19 are installed on the upper side of the base plate 1.

[0036] Specifically, the collection box 19 corresponds to the baffle 12, and the upper end of the fuel tank 18 is equipped with multiple combustion pipes 20. The upper and lower ends of the combustion barrel 2 are provided with air inlets and outlets. The multiple combustion pipes 20 are located inside the combustion barrel 2. Through the fuel tank 18, power can be provided to the multiple combustion pipes 20, so that the multiple combustion pipes 20 can burn the natural gas exhaust gas, thereby removing unqualified gases in the natural gas exhaust gas, thus ensuring environmental compliance and recycling qualified gases.

[0037] Working steps: 1. When natural gas exhaust needs to be filtered, first open the valve at another gas pipe 22, then introduce the natural gas exhaust into the combustion chamber 2 through the other gas pipe 22, and start the fuel tank 18. At this time, the fuel tank 18 provides power to multiple combustion pipes 20, so that multiple combustion pipes 20 burn the natural gas exhaust, thereby removing unqualified gases in the natural gas exhaust. Then open the valve at the outlet and one exhaust port. At this time, the burned natural gas exhaust is introduced into the filter box 3 through the transmission pipe 21. At the same time, one activated carbon filter plate filters and purifies it, and adsorbs the flue gas and harmful gases. Then, the filtered and purified natural gas exhaust is filtered and filtered again through the filter plate 4, and harmful particles are filtered and intercepted. At this time, open the valve at one gas pipe 22, and the second-filtered natural gas exhaust is discharged from the filter box 3 through one gas pipe 22. At this time, another activated carbon filter plate filters and purifies the natural gas exhaust again, thereby realizing the filtration and treatment of natural gas exhaust, ensuring environmental compliance and recycling of qualified gases.

[0038] 2. When it is necessary to clean the filter plate 4, start one of its motors 17. The output end of the motor 17 drives the first screw 13 to rotate, so that the first screw 13 engages with the middle thread of its sliding plate 7, thereby driving the sliding plate 7 to move up and down. The sliding plate 7 drives the two cleaning brushes 9 to move up and down synchronously. The other sliding plate 7 slides around the support rod 15, so that the four gears 10 mesh with multiple teeth 8 and rotate, thereby driving the two cleaning brushes 9 to rotate synchronously. At this time, the two cleaning brushes 9 rotate and sweep the opposite sides of the filter plate 4, which can sweep away the harmful particles accumulated and blocked on the filter plate 4. At the same time, multiple adjacent rubber blocks 14 are always in contact with the periphery of the two sliding plates 7, thereby realizing the cleaning work of the filter plate 4.

[0039] Third, when it is necessary to collect the harmful particles that have been swept away, another motor 17 is started. The output end of the other motor 17 drives the second screw 16 to rotate, so that the second screw 16 is threadedly engaged with the baffle 12, thereby opening the discharge port 11. At this time, the baffle 12 is slidably engaged on the inner side of the discharge port 11. When the two cleaning brushes 9 rotate and clean the filter plate 4, the harmful particles swept away fall into the collection box 19 through the discharge port 11 for collection and storage, thereby realizing the collection of harmful particles.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
