Detailed Description
The present invention will be described in further detail with reference to specific embodiments thereof for the purpose of making apparent the objects, contents and advantages thereof.
The invention provides a three-layer composite filter material for a high-power internal combustion engine, wherein a first three-layer structure of the filter material is sequentially provided with a coarse filter layer, a nano layer and a supporting layer according to the flowing direction of fluid;
the fiber section of the fiber of the rough filtering layer should be round or T, Y, V, X type differential synthetic fiber and natural fiber, with average diameter of 20-50um and length of 0.5-12mm, and is selected from one or more of fibric, mercerized fiber, polyester fiber, polypropylene fiber, aramid fiber, glass fiber and profiled fiber.
The nanometer layer is composed of 1-100% by mass of fibrillated fibers and 0-99% by mass of glass fibers, wherein the diameter of the trunk of the fibrillated fibers is less than 1um and is selected from one or more of tencel fibers, Richcel fibers, aramid fibers and acrylic fibers, and the average diameter of the glass fibers is 200-600 nm.
The supporting layer is made of plant fiber and/or non-plant fiber, the average length of the plant fiber is 0.5-10mm, the average diameter is 5-30um, and the supporting layer is selected from one or more of wood pulp fiber, bamboo fiber, cotton fiber, and deflection fiber; the average length of the non-plant fibers is 0.5-10mm, the average diameter is 5-20um, and the non-plant fibers are selected from one or more of nylon fibers, polyester fibers, polypropylene fibers, aramid fibers, glass fibers, Richcel fibers and tencel fibers.
Preferably, the quantitative ratio of the fibers of the coarse filter layer is 1-20g/m2The nano layer has a quantitative of 0.1-10g/m2The quantitative amount of the supporting layer is 10-150g/m2。
The invention discloses a three-layer composite air filter material for a high-power internal combustion engine, which aims to solve the problems of too fast resistance rise, short service life and the like of the traditional filter material for the high-power internal combustion engine under the working conditions of high flow rate, high dust density, high oil mist and the like. The three-layer composite air filter material is formed by a wet method at one time, the interlayer bonding strength is high, and as the nano-layer fibers provide thinner fibrils and fibril bundles, the fiber filling rate in unit volume is effectively improved, so that the filtering efficiency of the material is improved; and the surface layer adopts fibers with round or special-shaped cross sections, so that the surface bulk of the rough filtering layer can be effectively improved, and the dust holding capacity, namely the service life, of the material is improved. Because the running revolution of the high-power high-horsepower engine is high, the filter material is easy to form filter cakes by dust at high flow speed, and the filter material is bonded into blocks by the action of water vapor and oil mist, so that the resistance of the filter material can rise too fast to shorten the service life. The coarse filter layer of the material can effectively separate coarse particles at a high flow rate, and the nano layer can effectively resist finer particles, so that the formation of dust filter cakes can be effectively relieved, and meanwhile, the looseness of the coarse filter layer increases gaps of dust distribution to enable oil mist to be difficult to bond dust particles into blocks, so that the problem that the service life of the filter material is shortened in practical application is effectively solved.
The traditional gradient filtration deep material has high pollutant carrying capacity but poor recovery rate, and is easy to increase the resistance too fast in construction sites and the like or in regions with more dust in deserts and poor in back flushing performance. Although the traditional surface filtering material such as electrostatic spinning has high filtering efficiency and good back-blowing performance, dust in the area with oil mist in some air is easy to block holes on the surface with oil, and the back-blowing vibration does not come down, so that the resistance rises more quickly.
The filtering material is a three-layer one-step forming process, the operation is simple, wherein the surface layer and the middle layer form a gradient layer, the middle layer and the bottom layer form a surface filtering layer, and the surface filtering layer has good back flushing performance and high dirt receiving capacity due to the large pores of the surface layer, and is not afraid of oil mist weather. Because of the multilayer composite filtering material, the surface layer of the material provides the pollutant carrying capacity, the middle part provides the efficiency, so the material has the characteristics of gradient and surface filtration, the product has high pollutant carrying capacity, good back flushing performance and improved working condition applicability.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
