Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a high-efficiency fiber filter element. Background Art

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. Chemical plants, steel mills, pharmaceutical plants, coking plants, and oil refineries, in particular, produce strong odorous waste gases, seriously polluting the environment and affecting human health. Industrial waste gas includes both organic and inorganic waste gases. Organic waste gases primarily include various hydrocarbons, alcohols, aldehydes, acids, ketones, and amines; inorganic waste gases primarily include sulfur oxides, nitrogen oxides, carbon oxides, halogens, and their compounds. Filter elements are a commonly used filtration device in waste gas treatment and filtration.

[0003] The existing filter element has poor filtering performance, which greatly affects its effectiveness. This is especially true because the exhaust gas contains various organic and inorganic impurities, which are difficult to remove effectively and evenly, resulting in low removal efficiency. Furthermore, the filter element is difficult to secure within the setting machine, making it more difficult to clean and replace the filter element later.

[0004] This case was created to solve the above problems. Utility Model Content

[0025] The present invention will be further described in detail below through the accompanying drawings and examples.

[0026] like Figure 1-2 Shown: A high-efficiency fiber filter element, built into base 9 and used to filter exhaust gas from the setting machine, includes a circular filter element, the bottom of which is supported by a support 6. A connecting rod extends from support 6 to connect and secure it to base 9. The connecting rod includes a long rod 7, the bottom of which is threaded into a threaded groove in support 6, and the top of which extends above the circular filter element and is topped with a screw 8. An inverted U-shaped connecting plate 13 is placed on the interlayer. Screw 8 passes through this connecting plate 13 and is tightened by bolts 11 to provide support and limit the entire circular filter element.

[0027] A long groove 10 is provided on the base 9 relative to the connecting plate 13, so that both sides can be quickly placed and embedded in the limit position. The entire annular filter element is easy to load and can be quickly disassembled by removing the upper bolts 11.

[0028] like Figure 3-4 As shown: the annular filter element includes three layers of filter cotton rolled into a circle from the inside to the outside. The three layers of filter cotton are tightly fitted. The inner side of the three layers of filter cotton is provided with an iron mesh retainer 2, and the outer side is covered with a wire mesh 1.

[0029] It should be noted that the base has a through slot 12 that is the same size as or slightly larger than the iron mesh holder 2. The iron mesh holder 2 is relatively taller than the entire ring filter element and extends above the through slot 12, allowing exhaust gas to be completely filtered from the periphery inward before being discharged upward from the inside of the iron mesh holder 2. Furthermore, the relatively high iron mesh holder 2 is easy to remove, facilitating the rapid disassembly and assembly of the entire ring filter element.

[0030] The ring filter element has an inner diameter of 180mm and an outer diameter of 380mm. Generally, the thicker the filter pad, the higher the fan frequency required. Therefore, considering energy conservation standards and environmental safety, a 132kW fan with a frequency of approximately 25Hz is used.

[0031] During operation, cooled exhaust gas is blown into the housing 9 by a blower, filtered through three layers of filter cotton (synthetic fiber, high-temperature resistant, flame-retardant), and then discharged upward into the inner cavity. The outermost layer, filter cotton 1 (3), is conventional adsorption (flame-retardant), serving as a primary filter layer for oil removal, allowing the oil layer to quickly slide off. The middle layer, filter cotton 2 (4), has a relatively low density and high thickness, serving as a medium-efficiency filter layer for smoke removal. The innermost layer, filter cotton 3 (5), has a high density and low thickness, serving as a filter layer for removing microparticles.

[0032] The main consideration is that there are a lot of impurities on the outermost side of the ring filter element, which will be flushed during use. The impurities will seep down along the outer wire mesh 1 with the liquid. If the horizontal part of the conventional wire mesh 1 is easy to collect the wastewater on the upper side and not easy to seep down, it will cause secondary pollution at the junction of the ring filter element and the horizontal wire mesh. Figure 5-6 As shown, the improvement of this solution lies in that the outer wire mesh 1 used for covering is designed to be staggered in an inclined pattern similar to a diamond shape instead of the original crisscross pattern. The junctions of the staggered wires form wastewater nodes 14. This allows the wastewater on the relatively upper side to flow smoothly downward along all the inclined wire meshes and gather at the wastewater nodes 14 at the wire junctions. It can not only seep down into the inclined wire mesh, but also drip when the accumulated wastewater is large, thus improving the cleaning effect.

[0033] Secondly, the multi-layer filter cotton of the annular filter element is not completely flat, resulting in the upper side not being level and unable to fit with the inner wall of the base 9, causing the exhaust gas to leak directly from the upper side without being filtered through the circumferential filter cotton layers, greatly affecting the exhaust gas filtration efficiency. Therefore, see the attached Figure 7 As shown, a sealing cap 15 is fitted onto the top of the annular filter element, pressing down the multi-layer filter cotton of the annular filter element. Furthermore, it is preferred that the outer side of the sealing cap 15 be formed into a ring-shaped body extending circumferentially downward to fit over the outer surrounding wire mesh 1. This is because the wire mesh can be horizontal as a whole, and thus, it is easier to tightly adhere to the annular filter element through the lateral periphery to form a secondary seal, thereby achieving a better sealing effect.

[0034] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content of the specification, and its protection scope must be determined according to the scope of the claims.
