Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter media technology, specifically to filter media for oily dust filtration. Background Technology
[0002] Currently, in dust removal and purification systems, the filter media used generally have a three-layer or two-layer structure, namely coarse fiber + base fabric + fine fiber surface layer, or base fabric + fine (coarse) fiber structure. With the increasing environmental protection requirements in my country and the growing harm of smog to human health, developing a new type of filter media that improves purification and filtration efficiency has become an urgent need for the environmental protection industry. Existing filter media, due to their coarse fibers, large pores, and simple structure, result in relatively low dust removal and purification efficiency, leading to relatively high dust emissions, especially ultrafine dust emissions, causing pollution to the surrounding environment and affecting people's production, lives, and health.
[0003] In the current process of using oil and dust filter media, the filter media is filtered according to the personnel's usage, which results in poor filter media coverage. As a result, the filter media becomes loose and fragmented after long-term use, which reduces the filtration efficiency. At the same time, the filter media only filters a single type of material, which limits the applicability of the material and results in low filtration accuracy. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a special filter material for oily dust filtration, which has the advantages of all-round coating of the filter material and improved filtration performance, thus solving the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a filter material for filtering oily dust, comprising a fiber surface layer, a high-temperature resistant adhesive installed at the bottom of the fiber surface layer, a dust-attracting layer at the bottom of the fiber surface layer, a first fiber mesh layer installed at the bottom of the dust-attracting layer, a base fabric layer fixedly installed at the bottom of the first fiber mesh layer, an activated carbon filter material fixedly installed at the bottom of the base fabric layer, a PE filter material fixedly installed at the bottom of the activated carbon filter material, a glass fiber layer fixedly installed at the bottom of the PE filter material, a second fiber mesh layer fixedly installed at the bottom of the glass fiber layer, an adsorption layer fixedly installed at the bottom of the second fiber mesh layer, a nanofiber layer installed at the bottom of the adsorption layer, and a coating layer installed at the top of the nanofiber layer.
[0006] As a preferred technical solution of this utility model: the fiber surface layer, dust-receiving layer, first fiber mesh layer, base fabric layer, activated carbon filter material, PE filter material, glass fiber layer, second fiber mesh layer, adsorption layer, and nanofiber layer have the same size and are bonded to each other.
[0007] As a preferred technical solution of this utility model: the dust-receiving layer is located between the fiber surface layer and the first fiber web layer, and the dust-receiving layer is located on the outer wall of the activated carbon filter material and the PE filter material.
[0008] As a preferred technical solution of this utility model: the activated carbon filter material consists of several particles, and the particles are located on the inner wall of the fiber surface layer and the nanofiber layer.
[0009] As a preferred technical solution of this utility model: the PE filter material and the activated carbon filter material are mixed and located on the inner wall of the fiber surface layer and the nanofiber layer, and the PE filter material is made of polymer material.
[0010] As a preferred technical solution of this utility model: the coating layer and the high-temperature resistant adhesive are applied to the top of the nanofiber layer and the bottom of the fiber surface layer, respectively, and the coating layer and the high-temperature resistant adhesive are located around the bottom of the fiber surface layer and the top of the nanofiber layer.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This oil-dust filtration media has a coating layer and a high-temperature resistant adhesive located around the bottom of the fiber surface layer and the top of the nanofiber layer, respectively. This ensures that the fiber surface layer and the nanofiber layer are on the outermost layer of the filter media. The coating layer and the high-temperature resistant adhesive fix the fiber surface layer and the nanofiber layer to the outside of the filter media, forming a protective layer on the surface of the filter media to prevent corrosion. By installing a first fiber mesh layer and a second fiber mesh layer, the shape and stability of the filter media are maintained, increasing the strength and stability of the filter mesh and preventing the filter media from shifting or spreading during use.
[0013] 2. This oil and dust filtration media features several particles located on the inner walls of the fiber surface layer and nanofiber layer, giving the activated carbon filter media a porous, hydrophilic, and highly adsorption capacity. It is commonly used for organic gas filtration. When oil and dust pass through the activated carbon filter media layer, the dust impurities are adsorbed in the pores, thus achieving a purification effect. The PE filter media, located between the activated carbon filter media and the fiber surface layer and nanofiber layer, provides strong acid and alkali resistance for oil and dust filtration, making it suitable for various environments without causing secondary pollution and improving the filtration accuracy of the material.

[0025] In a preferred embodiment: the dust-receiving layer 2 is located between the fiber surface layer 1 and the first fiber web layer 3, and the dust-receiving layer 2 is located on the outer wall of the activated carbon filter material 5 and the PE filter material 6.
[0026] In the above structure, the dust-receiving layer 2 uses physical barriers and inertial collisions to intercept dust particles in the flue gas, preventing them from entering the internal structure of the filter material, reducing clogging of the internal filter material, and extending the service life of the filter material.
[0027] In a preferred embodiment, the activated carbon filter material 5 consists of several particles, and these particles are located on the inner walls of the fiber surface layer 1 and the nanofiber layer 10.
[0028] In the above structure, several particles are located on the inner wall of the fiber surface layer 1 and the nanofiber layer 10, which makes the activated carbon filter material 5 porous, hydrophilic and highly adsorbent. It is often used for organic gas filtration. When oil dust passes through the activated carbon filter material 5 layer, dust impurities are adsorbed in the pores, thereby playing a purification role.

The coating layer 11 and high-temperature resistant adhesive 12 fix the fiber surface layer 1 and nanofiber layer 10 to the outside of the filter media, forming a protective layer on the surface of the filter media to prevent corrosion and clogging, thereby extending the service life of the filter media and improving filtration efficiency. By installing the first fiber mesh layer 3 and the second fiber mesh layer 8, the shape and stability of the filter media are maintained, increasing filtration efficiency. The strength and stability of the mesh prevent the filter media from shifting or scattering during use. Several particles are located on the inner wall of the fiber surface layer 1 and the nanofiber layer 10, giving the activated carbon filter media 5 a porous, hydrophilic, and highly adsorption capacity. It is commonly used for organic gas filtration. When oil dust passes through the activated carbon filter media 5 layer, dust impurities are adsorbed in the pores, thus playing a purification role.
