When the motor 6 rotates, it will drive the main shaft to rotate, and the rotation of the main shaft will drive the two stirring blades 7 to rotate together, so as to achieve the purpose of breaking up the desulfurizer and fully mixing it with the biogas. The inner part of the outer barrel 2 is fixedly connected to the inner barrel 8.

[0028] Reference Figure 2 The bottom end of the feed port 4 is fixedly connected to the top of the inner barrel 8, and the bottom end of the exhaust pipe 3 is fixedly connected to the top of the inner barrel 8.

The outside of the inner barrel 8 is fixedly connected with a condenser 9, and the bottom end of the outer barrel 2 is fixedly connected with a storage box 10. The condenser 9 here is used to condense the moisture in the biogas, so that it adheres to the inner wall of the inner barrel 8 and then flows into the interior of the storage box 10 along the inner wall of the inner barrel 8.

[0029] Reference Figure 2-3 The outside of the storage box 10 is slidably connected to the inner wall of the table body 1. Two grooves 12 are opened inside the left side of the table body 1. The outside of the storage box 10 is slidably connected to the inner wall of the groove 12. If you want to remove the storage box 10 here, you can first rotate the storage box 10 so that its two protrusions are aligned with the two grooves 12 opened inside the table body 1, and then gently pull down to remove the storage box 10. A connecting pipe 11 is fixedly connected to the bottom end of the right side of the outer barrel 2.

[0030] Reference Figure 2 The connecting pipe 11 here is used to circulate the condensate inside the condenser tube 9 to keep it at a low temperature at all times so as to condense the moisture in the biogas.

This is the entire condensation circulation system. The right side of the top of the air box 13 is fixedly connected with a water inlet 15. The water inlet 15 here is used to pour the condensate. The front end of the air box 13 is fixedly connected with an outer box 17. The upper and lower ends of the inner wall of the outer box 17 are fixedly connected with a top plate 18. The outer box 17 here provides support for the top plate 18.

[0032] Reference Figure 4-5 A special-shaped strip 19 is fixedly connected to the adjacent side of the two top plates 18, and a filter plate 20 is slidably connected to the inner wall of the air box 13. The filter plate 20 here can filter the biogas after reacting with the desulfurizer to make it purer. At the same time, its bottom end can filter the condensate to keep it at a low temperature. A motor 21 is fixedly connected to the top of the rear end of the special-shaped strip 19, and the rear end of the motor 21 is fixedly connected to the front top of the filter plate 20. The driving end of the motor 21 is fixedly connected to the main pulley 22.

[0033] Reference Figure 5The motor 21 here will drive the main pulley 22 thereon to rotate under the drive of electricity. The outer side of the main pulley 22 is provided with a belt 23. When the main pulley 22 here rotates, it will drive the belt 23 thereon to rotate. The inner wall of the bottom end of the special-shaped strip 19 is rotatably connected to the slave pulley 24. The inner wall of the belt 23 is sleeved on the outside of the slave pulley 24. The rotation of the belt 23 will drive the rotation of the slave pulley 24 to form a linkage. The front end outer side of the belt 23 is fixedly connected to a rotating column, and the outer side of the rotating column is slidably connected to a hanging brush 25.

[0034] Reference Figure 4-5 The belt 23 here will drive the rotating column on it to rotate when it rotates, thereby driving the hanging brush 25 to move up and down, so that it can clean the pollutants on the surface of the filter plate 20. The inner wall of the hanging brush 25 contacts the outside of the filter plate 20, and the rear end of the hanging brush 25 is slidably connected to the inner wall of the air box 13. The inner wall of the hanging brush 25 is slidably connected to the left and right sides of the special-shaped strip 19. The left and right sides of the bottom end of the special-shaped strip 19 are fixedly connected with the bottom block 26, and the front end of the bottom block 26 is fixedly connected to the bottom end of the inner wall of the outer box 17.

[0035] Reference Figure 2 and Figure 5 The outer box 17 here provides stable support for the bottom block 26, making it more stable. The adjacent sides of the two bottom blocks 26 are in contact with the left and right sides of the filter plate 20 respectively. The right bottom end of the filter assembly is fixedly connected with an outlet 27, from which the filtered biogas will be discharged and collected by the staff.

[0036] Working principle: When using this device, the staff can first transport the biogas through the exhaust pipe 3 to the inside of the outer barrel 2 at the top of the table body 1, that is, the inside of the inner barrel 8, and then pour the desulfurizer into the feed port 4, and then start the motor 6 in the support block 5. The motor 6 will drive the main shaft to rotate, and the main shaft further drives the two stirring blades 7 thereon to rotate. At this time, the stirring blades 7 can not only break up the desulfurizer, but also make the biogas evenly distributed everywhere, so that it can fully mix and react with the desulfurizer.

[0037] The function of the condenser 9 here is to separate the moisture in the biogas and improve the purity of the biogas. The separated moisture will slide into the storage box 10 along the inner wall of the inner barrel 8. If you want to take down the storage box 10, you can rotate it until the protrusion engages with the groove 12, and then pull it down to take down the storage box 10. The dehydrated biogas can further enter the interior of the air box 13 along the connecting pipe 14, and the condensate can be poured into the interior of the air box 13 through the water inlet 15.

[0038] The condensate in the condenser 9 will be drawn out from the connecting pipe 11 under the action of the water pump 16 and flow out from the top of the water pump 16, thereby forming a condensation circulation structure. At this time, the biogas will be further filtered through the filter plate 20 to make it purer. However, after long-term use, a lot of pollutants will be deposited on the surface of the filter plate 20. At this time, the motor 21 on the special-shaped strip 19 can be started, and the motor 21 drives the main pulley 22 to rotate.

[0039] When the main pulley 22 rotates, it drives the belt 23 and the slave pulley 24 to move, and the movement of the belt 23 drives the rotating column thereon to move, so that the hanging brush 25 moves up and down, thereby cleaning the surface of the filter plate 20, and the filtered biogas will be discharged from the outlet 27.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
