Detailed Implementation

[0018] 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.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-2 As shown, this embodiment provides an integrated biogas desulfurization and dust removal purification device, including a main body 1. A first venturi tube 6 and a second venturi tube 7 are respectively arranged at the bottom of the main body 1. The first venturi tube 6 and the second venturi tube 7 are arranged opposite to each other. Biogas flows through the first venturi tube 6, and dust removal liquid flows through the second venturi tube 7. An atomizing head is provided at the end of the second venturi tube 7. A partition 10 is provided inside the main body 1. One end of the partition 10 is fixedly connected to the inner wall of the main body 1, and a gap is provided between the other end and the inner wall of the main body 1. A mixing component is provided above the partition 10. A support plate 15 is provided above the mixing component. An opening is provided between one end of the support plate 15 and the inner wall of the main body 1. A desulfurization tank 18 is fixedly connected to the top surface of the support plate 15. A bend 17 is connected to one side of the desulfurization tank 18. A one-way valve is provided inside the bend 17, and the end of the bend 17 is adapted to the opening.

[0021] This invention achieves preliminary mixing and dust removal of biogas and dust removal liquid by setting up opposing first Venturi tubes 6 and second Venturi tubes 7. The first Venturi tube 6 carries biogas, and the second Venturi tube 7 carries dust removal liquid and has an atomizing head at its end. The baffle 10 allows the gas and liquid to rise above the baffle 10 for further processing after preliminary treatment below the baffle 10. The mixing assembly is used to mix the gas and liquid. The support plate 15, the opening, and the connection between the desulfurization tank 18 and the bend 17 provide channels and structural support for the subsequent desulfurization process, enabling the device to complete an integrated purification process of desulfurization and dust removal.

[0022] A further optimized design includes a mixing component comprising a connecting shaft 13 rotatably connected to the inner wall of the main body 1. The output shaft of a motor 12 is fixedly connected to the end of the connecting shaft 13, and several blades 14 are mounted on the connecting shaft 13. The connecting shaft 13 in the mixing component is fixedly connected to the output shaft of the motor 12. The motor 12 drives the connecting shaft 13 to rotate, which in turn drives the blades 14 to rotate. This design enhances the mixing effect of biogas and dust removal liquid, ensuring sufficient contact between the two, improving dust removal efficiency, and creating better conditions for the subsequent desulfurization process.

[0023] The design is further optimized by embedding a water inlet pipe 20 within the main body 1. The water inlet pipe 20 is connected to the second venturi tube 7, and an outlet pipe 11 is connected to the water inlet pipe 20. The top of the outlet pipe 11 is fixedly installed on the bottom surface of the support plate 15, and several nozzles 16 are installed on the outlet pipe 11. The dust-removing liquid sprayed from the nozzles 16 mixes with the biogas for secondary dust removal. The water inlet pipe 20, connected to the second venturi tube 7, provides dust-removing liquid to it. Simultaneously, the outlet pipe 11 connects to the water inlet pipe 20 and is installed on the bottom surface of the support plate 15. The dust-removing liquid sprayed from the nozzles 16 on the outlet pipe 11 mixes with the biogas for secondary dust removal. This design further increases the contact area and contact time between the biogas and the dust-removing liquid, improving the dust removal effect and ensuring that dust and other impurities in the biogas are more thoroughly removed.

[0024] In a further optimized design, a collection tank 8 is installed within the main body 1, located between the first Venturi tube 6 and the second Venturi tube 7. The collection tank 8, situated between the first Venturi tube 6 and the second Venturi tube 7, collects wastewater and impurities generated after treatment from the first Venturi tube 6 and the second Venturi tube 7, facilitating subsequent treatment and discharge, and preventing the accumulation of wastewater and impurities within the device, which could affect its normal operation.

[0025] The design is further optimized by tilting the baffle 10, with a connecting pipe 9 at its lower end, the bottom of which connects to the collection tank 8. This tilted design allows liquid and impurities on the baffle 10 to flow naturally towards the connecting pipe 9 and then into the collection tank 8, facilitating collection and treatment and improving the automation and operational efficiency of the device.

[0026] To further optimize the design, several buffer plates 19 are installed inside the desulfurization tank 18, allowing the biogas to remain within the tank for a longer period. This ensures sufficient contact between the biogas and the desulfurizing agent, improving the desulfurization effect, guaranteeing the effective removal of sulfides from the biogas, and ultimately enhancing its quality.

[0027] A further optimized design includes an air inlet pipe 4 installed on one side of the bottom of the main body 1, which connects to the first venturi tube 6. An air outlet pipe 3 is connected to the top surface of the main body 1, with the end of the outlet pipe 3 furthest from the main body 1 connected to the dryer 2. The air inlet pipe 4, connected to the first venturi tube 6, provides a biogas source for the device; the air outlet pipe 3, connected to the top surface of the main body 1, connects to the dryer 2 at the end furthest from the main body 1. This design allows the biogas, after desulfurization and dust removal treatment, to be discharged through the outlet pipe 3 and enter the dryer 2 for drying, removing moisture and improving the purity and quality of the biogas to better meet usage requirements.

[0028] A further optimized design incorporates a boss 5 on the bottom surface of the main body 1, with the dryer 2 positioned on top of the boss 5. This design creates a height difference between the dryer 2 and the main body 1, facilitating the connection of the gas outlet pipe 3 and the delivery of biogas. It also benefits the installation and maintenance of the dryer 2, improving the overall stability and reliability of the device.
