Description

Technical Field

[0001] This utility model relates to the field of biogas purification technology, specifically to a filtration mechanism. Background Technology

[0002] Biogas filtration is an important step in the biogas production and utilization process. Its main purpose is to remove impurities and harmful components from biogas to improve its quality and safety and meet the requirements for subsequent utilization. It usually involves multiple steps such as pretreatment, desulfurization, and fine filtration. In the existing technology, each piece of equipment occupies a large area, is time-consuming and labor-intensive to assemble, and is placed outdoors, which accelerates the aging of the equipment. Therefore, a filtration mechanism is proposed to solve this problem. Utility Model Content

[0003] In view of this, the present invention provides a filtration mechanism that integrates activated carbon adsorption equipment, desulfurization equipment, dehydration equipment and fine filter into a housing, thereby reducing the equipment's footprint, slowing down its aging process, facilitating later maintenance, and allowing for direct overall relocation using lifting equipment when necessary.

[0004] To solve the above-mentioned technical problems, this utility model provides a filtration mechanism, including a box, which contains an activated carbon adsorption device, a desulfurization device, a dehydration device, and a fine filter. The desulfurization device is connected to both the activated carbon adsorption device and the desulfurization device, and the fine filter is connected to the dehydration device.

[0005] The activated carbon adsorption equipment is equipped with an inlet and an outlet. It is used to remove large particulate impurities mixed in biogas, reducing their damage to subsequent desulfurization equipment.

[0006] The desulfurization equipment includes a desulfurization tank and a feed pump. The desulfurization tank is equipped with an air inlet, an air outlet, a water inlet, and a water outlet. A first connecting pipeline is provided between the air inlet and the discharge pipe. The feed pump is equipped with a water supply pipeline connected to the water inlet and a water pumping pipeline connected to the water outlet. The desulfurization equipment is used to remove hydrogen sulfide mixed in biogas, reduce harmful gases in biogas, and improve the quality of biogas.

[0007] The dehydration equipment is equipped with a first connection port and a second connection port. A second connecting pipe is provided between the connection port and the gas outlet. The dehydration equipment removes a large amount of water from the biogas, thereby improving the combustion quality of the biogas.

[0008] The second connection port is equipped with a third connection pipe that communicates with the fine filter.

[0009] A cooling fan is also installed on the top of the enclosure, and the corresponding cooling fan has mounting holes. The cooling fan is used to dissipate heat from the equipment during long-term operation or when the temperature is high.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0011] 1. By integrating activated carbon adsorption equipment, desulfurization equipment, dehydration equipment, and fine filter into the housing, the equipment footprint is reduced, and it is easier to maintain and repair later. If necessary, it can be moved directly as a whole using lifting equipment.

[0012] 2. Desulfurization equipment is used to remove hydrogen sulfide mixed in biogas, reduce harmful gases in biogas, and improve the quality of biogas. Attached Figure Description
