Description

Technical Field

[0001] This utility model relates to the field of biogas production technology, specifically to an integrated anaerobic gas production and storage device. Background Technology

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the development and utilization of renewable energy has become an important issue. Biogas, as a clean energy source, is mainly produced by the anaerobic fermentation of organic waste (such as manure and agricultural waste), and its main components are methane and carbon dioxide. The utilization of biogas can not only reduce dependence on fossil fuels but also effectively treat organic waste and reduce environmental pollution. Currently, biogas technology is widely used in agriculture, animal husbandry, and organic waste treatment.

[0003] In existing technologies, anaerobic fermentation equipment typically uses a single-tank structure, requiring the entire fermentation tank to be opened for feeding. This leads to complex operation and easily compromises the airtightness of the fermentation environment, affecting fermentation efficiency and biogas production. This design not only increases operational difficulty but may also introduce oxygen, interfering with the anaerobic fermentation process and reducing the methane concentration in the biogas.

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.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] An integrated anaerobic gas production and storage device includes a base 1, a bottom tank 2 fixedly installed at the top left side of the base 1, a frame 3 fixedly installed on the outer left side of the base 1, a top tank 4 movably installed on the front of the frame 3, a lifting mechanism provided between the frame 3 and the top tank 4, the lifting mechanism including a guide groove 6, a guide groove 6 opened in the middle of the frame 3, a lead screw 7 movably installed inside the guide groove 6, a motor 8 fixedly installed at the top middle of the frame 3, the output shaft of the motor 8 fixedly connected to the lead screw 7, a movable block 9 threadedly connected to the outside of the lead screw 7, and a fixedly installed front side of the movable block 9. A lifting frame 10 is fixedly installed with a hanging pipe 11 on the lower left side of the lifting frame 10. The top of the top tank 4 is fixedly connected to the hanging pipe 11. The output shaft of the motor 8 passes through the hanging pipe 11 and is fixedly installed with a stirrer 12 on the top tank 4. A safety valve 13, an oxygen concentration sensor 14, and a methane concentration sensor 15 are connected sequentially from top to bottom on the front of the top tank 4. Connectors 16 are fixedly installed on both sides of the top of the top of the top tank 4. A sealing pipe 17 is fixedly connected to the bottom of the top tank 4. A sealing groove 18 is opened at the outer ring of the top of the bottom tank 2. A sealing ring 19 is movably installed inside the sealing groove 18.

[0026] In this embodiment, a separate design of bottom tank 2 and top tank 4 is adopted. The lifting mechanism realizes the raising and lowering of top tank 4, which facilitates the feeding operation. When feeding, top tank 4 is raised to expose the opening of bottom tank 2, making it convenient to put organic waste into bottom tank 2. After feeding is completed, top tank 4 is lowered and tightly connected to bottom tank 2 through sealing pipe 17 and sealing ring 19 to ensure the airtightness of fermentation environment. This simplifies the feeding process and significantly improves the convenience of operation and the practicality of equipment.

[0027] like Figure 1 and Figure 3 As shown, a gas storage tank 5 is fixedly installed at the top right side of the base 1, a pressure sensor 26 is fixedly installed at the upper right side of the gas storage tank 5, an exhaust pipe 27 is fixedly installed at the lower right side of the gas storage tank 5, a gas purification mechanism is provided between the top tank 4 and the gas storage tank 5, the purification mechanism includes a nitrogen gas purifier 20, the nitrogen gas purifier 20 is fixedly installed at the middle of the top of the base 1, an exhaust pipe 21 is fixedly installed at the upper right side of the top tank 4, a switch valve 22 is fixedly installed in the middle of the exhaust pipe 21, a bellows 23 is detachably installed between the inlet end of the nitrogen gas purifier 20 and the exhaust pipe 21, a compression pump 24 is fixedly installed at the outlet end of the nitrogen gas purifier 20, and an input pipe 25 is fixedly installed between the outlet end of the compression pump 24 and the inlet end of the gas storage tank 5.

[0028] In this embodiment, air replacement is achieved through two connectors 16 at the top of the top tank 4, using carbon dioxide to replace the internal air, ensuring an anaerobic fermentation environment and avoiding interference from oxygen in the fermentation process. At the same time, the stirrer 12 continuously stirs the raw materials in the bottom tank 2 under the drive of the motor 8, ensuring uniform fermentation and improving gas production efficiency.

[0029] Working Principle: First, the top tank 4 is raised by the lifting mechanism, exposing the opening of the bottom tank 2, facilitating the feeding of manure or other organic waste into the bottom tank 2. After feeding, the top tank 4 is lowered and tightly connected to the bottom tank 2 via the sealing pipe 17 and sealing ring 19, ensuring the airtightness of the fermentation environment. Before fermentation begins, air replacement is performed through the two connectors 16 at the top of the top tank 4: carbon dioxide is injected into the top tank 4 through the air inlet pipe, replacing the internal air and ensuring an anaerobic fermentation environment. Subsequently, microorganisms in the bottom tank 2 decompose organic matter under anaerobic conditions, producing biogas (mainly composed of methane and carbon dioxide). Simultaneously, the stirrer 12, driven by the motor 8, continuously stirs the raw materials, ensuring uniform fermentation and improving gas production efficiency. As fermentation progresses, biogas gradually accumulates in the top tank 4. The oxygen concentration sensor 14 and methane concentration sensor 15 monitor the gas composition in real time, ensuring that the methane concentration in the biogas reaches a usable level. When the biogas pressure reaches the set value, the safety valve 13 automatically opens to prevent excessive pressure inside the tank. Next, the biogas enters the gas purification unit through the gas outlet pipe 21, where impurities such as carbon dioxide and hydrogen sulfide are removed in the nitrogen gas purifier 20 to obtain high-purity methane gas. The purified methane gas is compressed by the compressor pump 24 and transported to the gas storage tank 5 through the input pipe 25. The pressure sensor 26 in the gas storage tank 5 monitors the gas storage pressure in real time to ensure that it operates within a safe range. When methane is needed, the gas is discharged through the exhaust pipe 27 for subsequent use.

[0030] It should be noted that the model number of the nitrogen gas purifier is: PSA-M3200-G2.
