Description

Filter device for hydrogen extraction power generation equipment The present invention relates to a filtration device for power generation equipment, and more specifically, to a hydrogen extraction type filtration device for power generation equipment and a method for manufacturing the same, which is applied to power generation equipment that extracts hydrogen to generate electricity and improves filtration efficiency. In general, hydrogen is the lightest element and a colorless, tasteless, and odorless gas; because it does not emit pollutants when burned, it is widely utilized as a pollution-free energy source to replace coal and petroleum. This hydrogen is extracted through the electrolysis of water introduced from the outside. The hydrogen extracted in this way is a combustible gas that ignites easily when in contact with air or oxygen, and the hydrogen-air mixture can exhibit explosive combustion reactions depending on the conditions. In particular, hydrogen power plants generate energy through chemical reactions, resulting in low noise and no harmful emissions, making them a highly sought-after eco-friendly energy source located within urban areas. Meanwhile, in the process of extracting hydrogen from power generation equipment, a filtration device is installed to remove impurities contained in the incoming water; however, since the filtration device in conventional technology consists of a simple perforated plate, high-purity filtration cannot be achieved, resulting in a problem of limited filtration efficiency. In addition, since the perforated plate is made of lightweight aluminum, there was a problem where vibration and deformation occurred due to the incoming water pressure.

FIG. 2 is a perspective view of the combination of the perforated plate body and the mesh net of the present invention. Figure 3 is an enlarged view of section A of Figure 2. FIG. 4 is a planar structural diagram of the filtration device of the present invention. FIG. 5 is a cross-sectional structural diagram of the filtration device of the present invention. FIG. 6 is a cross-sectional view of the separated state of the filtration device of the present invention. FIG. 7 is an enlarged cross-sectional view of a filtration device in a separated state according to another embodiment of the present invention.

Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art. Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted. First, the configuration of a filtration device for hydrogen extraction type power generation equipment according to one embodiment of the present invention is as follows through FIGS. 1 to 6. The filtration device in this embodiment comprises a perforated plate body (10) having a plate-like structure forming a flat surface and a plurality of perforations (12) formed through it in a circular shape, and a mesh net (20) having a fine mesh through-hole structure smaller than the perforations (12) and fixed to the bottom surface of the perforated plate body (10) by spot welding. At this time, a reinforcing pipe (11) having a cylindrical shape with an internal penetration is integrally welded and fixed at multiple locations on the upper surface of the perforated plate body (10). In addition, the spot welding is performed at regular intervals along two welding lines formed at regular intervals along the edge portion, and the mesh net (20) is structured to be expanded by a certain width (d) compared to the perforated plate body (10), so that elastic support of the perforated plate body (10) can be achieved by utilizing the elasticity of the mesh net (20) mounted in the flow path when the filtration device is installed. We will now examine the manufacturing process and the effects of use of the filtration device of the present invention having such a configuration. The filtration device of the present invention is installed on the inlet path of water flowing in for hydrogen extraction and performs the function of capturing and filtering foreign substances. That is, as the incoming water fi
