Description

Technical Field

[0001] This utility model relates to the technical field of biogas pretreatment equipment, and in particular to a treatment device for separating hydrogen sulfide from biogas. Background Technology

[0002] When using biogas for power generation, hydrogen sulfide in the biogas needs to be separated to reduce air pollution during the biogas power generation process. Existing equipment for biogas desulfurization is very inconvenient to replace the desulfurizing agent, and the desulfurizing agent inside the equipment is difficult to make sufficient contact with sulfides, resulting in low efficiency of the desulfurizing agent.

[0003] Regarding the automatic replacement device for desulfurizing agent in biogas pretreatment disclosed in patent publication number "CN208414350U", the operation of the first and second stirring mechanisms keeps the iron oxide desulfurizing agent mixture in a flowing state, which can improve the utilization efficiency of the desulfurizing agent mixture and facilitate the replacement of the desulfurizing agent solution. However, when replacing the desulfurizing agent solution, it is difficult to completely remove the desulfurizing agent mixture adhering to the inner wall of the tank. At the same time, relying solely on the desulfurizing agent is insufficient to completely separate hydrogen sulfide from the biogas. Therefore, this application proposes a treatment device for separating hydrogen sulfide from biogas. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a treatment device for separating hydrogen sulfide from biogas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A treatment device for separating hydrogen sulfide from biogas includes a tank. A motor bracket is fixedly connected to the top of the tank, and a motor is fixedly installed on the motor bracket. A support plate is fixedly welded to one side of the tank. A bellows is located below the support plate and connected to one side of the tank. A first transmission wheel is fixedly connected to the motor drive shaft and rotatably connected to the top of the tank. A second transmission wheel is located on one side of the first transmission wheel and rotatably connected to the top of the support plate. A belt is located below the motor and wound around the outside of the first and second transmission wheels. A first bevel gear is fixedly connected to the bottom of the second transmission wheel and located inside the bellows. A filter screen is fixedly connected to the inner wall of the bellows. The first bevel gear meshes with a second bevel gear and rotatably connects to the filter screen. A fan is fixedly connected to one end of the second bevel gear near the tank. Two slide rails are located on one side of the filter screen and fixedly connected to the inner walls of the bellows on both sides. A rotating roller is fixedly connected to the bottom of the first transmission wheel and located inside the tank. Three scraper frames are fixedly connected to the side of the rotating roller.

[0007] Preferably, an input pipe is connected to one side of the tank, and a flange is fixedly connected to the end of the input pipe away from the tank. An output pipe is connected to one side of the tank, and an output valve is fixedly installed on the output pipe.

[0008] Preferably, the fan faces the connection point between the air box and the tank.

[0009] Preferably, the bellows has a slot at the top, and one end of each of the two slide rails passes through the slot.

[0010] Preferably, the filter screen has a plurality of fine holes.

[0011] Preferably, the three scraper frames are attached to the inner wall of the tank at a point away from the edge of the rotating roller.

[0012] This utility model has the following beneficial effects:

[0013] 1. Through components such as the first drive wheel, motor, and scraper frame, when the motor drives the first drive wheel to rotate the roller, the desulfurizing agent mixture of the three scraper frames is in a flowing state, thereby improving the separation effect of hydrogen sulfide in biogas more efficiently. In addition, when it is necessary to discharge the ineffective desulfurizing agent mixture, the desulfurizing agent mixture adhering to the inner wall of the tank can be completely removed, avoiding insufficient discharge.

[0014] 2. The prepared activated carbon blocks are inserted into the air box along the slide rail through the second drive wheel, the first bevel gear, the fan, and other components. When the second drive wheel causes the first bevel gear to rotate, the second bevel gear drives the fan to rotate. The negative pressure generated by the fan carries the biogas through the filter screen to the activated carbon blocks on the slide rail. The activated carbon blocks can further adsorb and separate hydrogen sulfide in the biogas, improving the separation effect. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A treatment device for separating hydrogen sulfide from biogas includes a tank 1, a motor bracket 4 fixedly connected to the top of the tank 1, an input pipe 3 connected to one side of the tank 1, a flange 2 fixedly connected to the end of the input pipe 3 away from the tank 1, through which desulfurizing agent can be added, and through the flange 2 to establish a connection with an external pipe, and an output pipe 14 connected to one side of the tank 1, on which an output valve 13 is fixedly installed, and by turning the output valve 13, the desulfurizing agent in the tank 1 can be discharged through the output pipe 14.

[0022] A motor 5 is fixedly mounted on a motor bracket 4. A support plate 9 is fixedly welded to one side of the tank body 1. A bellows 12 is located below the support plate 9 and connected to one side of the tank body 1. A slot is provided above the bellows 12, and one end of two slide rails 11 passes through the slot. Activated carbon blocks can be slidably inserted into the bellows 12 through the slot along the slide rails 11, making it convenient and efficient to replace activated carbon blocks. A first drive wheel 6 is fixedly connected to the drive shaft of the motor 5 and rotatably connected to the top of the tank body 1. A second drive wheel 8 is located on one side of the first drive wheel 6 and rotatably connected to the top of the support plate 9. A belt 7 is located below the motor 5 and wrapped around the outside of the first drive wheel 6 and the second drive wheel 8. A first bevel gear 10 is fixedly connected below the second drive wheel 8 and located inside the bellows 12. A filter screen 15 is fixedly connected to the inner wall of the bellows 12. The filter screen 15 has several fine holes that can effectively filter out impurities in the biogas. The first bevel gear 10 is meshed with the second bevel gear 16, which is rotatably connected to the filter screen 15. The second bevel gear 16 is fixedly connected to a fan 17 near the end of the tank 1. The fan 17 faces the connection between the air box 12 and the tank 1. In this way, the fan 17 accurately draws the biogas in the tank 1 into the air box 12. The filter screen 15 has two slide rails 11 on one side, which are fixedly connected to the inner walls of the air box 12 on both sides. The first drive wheel 6 is fixedly connected to a rotating roller 19 inside the tank 1. The rotating roller 19 is fixedly connected to three scraper frames 18 on the side. The three scraper frames 18 are attached to the inner wall of the tank 1 at the edge away from the rotating roller 19. When it is necessary to discharge the desulfurizing agent, the residual desulfurizing agent mixture on the inner wall of the tank 1 can be effectively scraped off.

[0023] When using this device, the activated carbon block is first slidably inserted into the air box 12 through the slot along the slide rail 11. Then, the motor 5 is started, causing the first drive wheel 6 to rotate the roller 19. The three scraper frames 18 on the roller 19 keep the desulfurizing agent mixture in a flowing state, thereby improving the separation effect of hydrogen sulfide in biogas more efficiently. At the same time, the first drive wheel 6 rotates the second drive wheel 8 through the belt 7. The second drive wheel 8 drives the first bevel gear 10 to rotate. Under the rotation of the first bevel gear 10, the second bevel gear 16 drives the fan 17 to rotate. The negative pressure generated by the fan 17 carries the biogas through the filter screen 15 to the activated carbon block on the slide rail 11. The activated carbon block can further adsorb and separate hydrogen sulfide in the biogas, improving the separation effect. Moreover, the activated carbon block can be inserted or removed through the slot on the air box 12 and the slide rail 11, making replacement convenient. When the desulfurizing agent fails, the desulfurizing agent mixture in the tank 1 can be discharged through the output pipe 14 by turning the output valve 13. At the same time, the three scraper frames 18 can completely remove the desulfurizing agent mixture that is stuck to the inner wall of the tank, so as to avoid insufficient discharge.
