Abstract

The invention discloses a polyamide filter material and a filter element for oil filtration. The filter material is made from a polyamide material and is of a hollow cylindrical structure prepared by mutually gluing and winding superfine fibers ejected by virtue of melt-blowing technical processing; the filter material is of a loose structure which is provided with filter holes different in pore diameters; the pore diameter distribution mode of the filter holes is as follows: the pore diameters are sequentially and gradually decreased from outside to inside along the cylindrical structure. By virtue of controlling the structural parameters of the filter material, filtration of oils such as fuel oil or lubricating oil is realized, the filter material has relatively high filtration precision, assimilative capacity and oil-water separation capability on the premise of ensuring oil resistance and alcohol corrosion resistance; the scheme breaks through the restriction that only hydrophobic materials can be selected as traditional filter materials so as to meet oil-water separation indexes; by virtue of fully using the characteristics such as high corrosion resistance and high reliability of the polyamide material in the oils, the filtration requirements of common oils are met.

Description

technical field [0001] The invention relates to a filter material, a preparation device and a preparation method thereof, in particular to a polyamide filter material for oil products, a filter element, a preparation device and a preparation method thereof. Background technique [0002] During the production, transportation and storage of engine fuel, a large number of impurities will be produced and mixed. Clean fuel oil will also produce pollutants such as metal oxides, precipitated colloids, and asphaltene after storage for a period of time. Severely polluted fuel will cause wear and carbon deposits in the engine's fuel injection system and combustion chamber, resulting in increased fuel consumption and a sharp increase in exhaust emissions after the fuel engine has been used for a period of time. The current general solution is to install an oil filter on the engine to remove impurities, colloids, asphaltene and moisture in the fuel to make the fuel clean. Clean fuel c...
