Description

Technical Field

[0001] This utility model belongs to the field of biogas purification technology, specifically referring to a gas purification device for biogas power generation. Background Technology

[0002] Biogas power generation is a process that uses biogas as fuel to generate electricity. Biogas is mainly composed of gases such as methane and carbon dioxide. It is a product of the fermentation of organic waste. Common sources include agricultural waste, sludge from urban sewage treatment plants, and food waste. However, biogas needs to be purified before it can be used for power generation. It needs to undergo purification treatments such as desulfurization and drying. Among these, the removal of hydrogen sulfide is particularly important. A common desulfurization method is to have the biogas react in a tank containing a desulfurizing agent.

[0003] However, most existing desulfurization units use a single desulfurization tank structure, which must be shut down and replaced after the desulfurizing agent is saturated, causing interruptions in biogas treatment and affecting power generation efficiency and continuous operation capability. In addition, replacing the desulfurizing agent requires special tools to disassemble multiple bolts or nuts, which is complicated and further increases the difficulty of maintenance and time cost. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a gas purification device for biogas power generation, which effectively solves the problems of inconvenient replacement of desulfurizing agent and reduced working efficiency.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A gas purification device for biogas power generation includes a base plate, on which a desulfurization tank and an auxiliary tank are arranged side by side. A fixed side plate is vertically fixed between the desulfurization tank and the auxiliary tank. Both the desulfurization tank and the auxiliary tank are provided with multi-layer horizontally arranged docking grooves. A bearing plate is inserted into the docking groove. A sealing strip that seals with the bearing plate is provided in the docking groove. A desulfurizing agent installation groove is provided on the bearing plate.

[0006] The desulfurization tank is equipped with an air inlet pipe at the bottom, which is connected to the auxiliary tank via a connecting pipe. The desulfurization tank is equipped with an air outlet pipe at the top, and the auxiliary tank is equipped with an exhaust pipe at the top that is connected to the air outlet pipe.

[0007] Preferably, the bearing plate is provided with a limiting hole, the fixed side plate is fixed with mounting blocks on both sides, the mounting block is vertically rotatably provided with a threaded rod, the threaded rod is threadedly connected with a limiting plate, the bottom of the limiting plate is fixed with a limiting post that can be inserted into the limiting hole, and the bottom of the threaded rod is provided with an end block.

[0008] Preferably, the desulfurizing agent installation tank is provided with uniformly distributed air vents or a mesh structure.

[0009] Preferably, the support plate is provided with an inwardly recessed hand groove.

[0010] Preferably, valves are installed on the outlet pipe, exhaust pipe, inlet pipe, and connecting pipe to control the gas flow and direction.

[0011] Preferably, a hydrogen sulfide concentration sensor is installed at the end of the gas outlet pipe.

[0012] Compared with the prior art, the present invention, by adopting the above-described structure, achieves the following beneficial effects:

[0013] 1. By setting up a parallel structure between the desulfurization tank and the auxiliary tank, the system can be switched without interrupting biogas treatment, ensuring continuous operation of the system.

[0014] 2. The combination of the limiting plate, threaded rod and limiting post enables the rapid fixing and release of the desulfurizing agent carrier plate, facilitating the replacement of the desulfurizing agent. Attached Figure Description

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, this utility model proposes a gas purification device for biogas power generation, including a base plate 1. A desulfurization tank 2 and an auxiliary tank 3 are arranged side-by-side on the base plate 1. A fixed side plate 4 is vertically fixed between the desulfurization tank 2 and the auxiliary tank 3. Both the desulfurization tank 2 and the auxiliary tank 3 are provided with multiple horizontally arranged docking grooves 5. A support plate 6 is inserted into the docking groove 5. A sealing block is provided on the end face of the insertion end of the support plate 6. When the support plate 6 is fully inserted into the docking groove 5, the sealing block is axially compressed between the end wall of the support plate 6 and the docking groove 5 to form an end face seal. Through the combination of radial sealing on the side wall and end face compression sealing, multiple sealing barriers are formed, greatly enhancing the reliability of the seal. The seal is frictionless during the pulling process, does not increase operating resistance, and achieves a reliable seal between the support plate 6 and the tank body. This effectively prevents biogas from leaking out of the gaps in the installation groove, ensuring that all airflow passes through the desulfurizing agent bed, thus guaranteeing desulfurization efficiency and safety. The support plate 6 is equipped with a desulfurizing agent installation groove 7 and an inwardly recessed hand groove 17, providing operators with a point of leverage. When pulling the support plate 6 for replacement, the operation is more convenient and labor-saving. The desulfurizing agent installation groove 7 is equipped with evenly distributed vent holes or a grid structure, which, while ensuring effective support for the desulfurizing agent, greatly increases the contact area between biogas and the desulfurizing agent, improving the efficiency of the desulfurization reaction and the utilization rate of the desulfurizing agent.

[0023] like Figure 1-4As shown, the desulfurization tank 2 is equipped with an air inlet pipe 8 at the bottom, which is connected to the auxiliary tank 3 via a connecting pipe 9. The desulfurization tank 2 is equipped with an air outlet pipe 10 at the top, and the auxiliary tank 3 is equipped with an exhaust pipe 11 connected to the air outlet pipe 10 at the top, realizing a parallel structure of two tanks. This allows for the replacement of the desulfurizing agent without interrupting biogas treatment, improving system continuity. Valves 18 are installed on the air outlet pipe 10, exhaust pipe 11, air inlet pipe 8, and connecting pipe 9 to control the gas flow and direction. The airflow path can be flexibly controlled through the valves 18 to achieve independent or parallel operation of the desulfurization tank 2 and the auxiliary tank 3. A hydrogen sulfide concentration sensor 19 is installed at the end of the air outlet pipe 10 to monitor the hydrogen sulfide content in the purified gas in real time, monitor the desulfurization effect in real time, and prompt the replacement of the desulfurizing agent or switching of the tank to ensure purification quality.

[0024] like Figure 1-4 As shown, the bearing plate 6 is provided with a limiting hole 12, and the fixed side plate 4 is fixed with mounting blocks 13 on both sides. A threaded rod 14 is vertically rotatably mounted on the mounting block 13. A limiting plate 15 is threadedly connected to the threaded rod 14. A limiting post 16 that can be inserted into the limiting hole 12 is fixed at the bottom of the limiting plate 15. The bearing plate 6 can be quickly locked and released through threaded transmission, which is convenient for disassembly and maintenance. An end block 20 is provided at the bottom of the threaded rod 14 for manually rotating the threaded rod 14 to drive the limiting plate 15 to move up and down. Fixing and releasing can be completed without special tools.

[0025] In practical use, biogas is introduced into desulfurization tank 2 through inlet pipe 8, and desulfurized through multiple layers of desulfurizing agent. The treated biogas is discharged through outlet pipe 10 for drying.

[0026] When the desulfurizing agent in the desulfurization tank 2 is saturated, open the valve 18 of the connecting pipe 9, and at the same time close the valves 18 of the air inlet pipe 8 and the air outlet pipe 10 of the desulfurization tank 2 to introduce biogas into the auxiliary tank 3 for continued desulfurization. At this time, the operator can rotate the end block 20 on the side of the desulfurization tank 2 to drive the threaded rod 14 to rotate, so that the limiting plate 15 moves upward and drives the limiting post 16 to disengage from the limiting hole 12 of the bearing plate 6. The bearing plate 6 can then be pulled out from the docking groove 5 to replace the desulfurizing agent. After the replacement is completed, reinsert the bearing plate 6, rotate the threaded rod 14 in the opposite direction to make the limiting plate 15 rise, and insert the limiting post 16 into the limiting hole 12 to complete the fixation.

[0027] The hydrogen sulfide concentration sensor 19 installed at the end of the gas outlet pipe 10 monitors the gas quality in real time. When the hydrogen sulfide concentration is detected to be rising, the operator is prompted to switch or replace the desulfurizing agent.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
