Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.

as shown in fig. 1, a filter element of a filter comprises a cylindrical outer cover 1 (made of metal material, and a plurality of oil inlet holes are arranged on the outer cover 1), and an upper end cover 2 and a lower end cover 3 which are respectively arranged at two axial ends of the outer cover 1, wherein an oil outlet 21 is arranged on the upper end cover 2; an upper sealing cover 11 and a lower sealing cover 12 are arranged in the outer cover 1, and a plurality of oil outlet holes 111 are arranged on the upper sealing cover 11 corresponding to the oil outlet 21; the outer cover 1 between the upper cover 11 and the lower cover 12 is filled with fiber particles 13 made of pulp, i.e. the sealing of the fiber particles 13 is achieved by the upper cover 11 and the lower cover 12. The particle size of the fiber particles 13 is 1-5 mm, and micropores with the aperture of 1-15 um are distributed on the fiber particles 13.

In the present embodiment, in order to ensure that there is sufficient space for filling the fibrous particles 13; during installation design, the outer end face of the upper cover 11 is attached to the inner end face of the upper cover 2, and the outer end face of the lower cover 12 is attached to the inner end face of the lower cover 3. In addition, the specific surface area of the fiber particles 13 is large, so that the dust holding rate of the filter element of the filter is far greater than that of the filter element of the common filter, and the service life of the filter element of the filter can be prolonged.

In order to optimize the filtering effect of the filter element, an outer cover filter screen 4 is arranged on the inner peripheral wall of the outer cover 1, and an upper cover filter screen 5 is arranged on the inner side surface of the upper cover 11. Wherein, the outer cover filter screen 4 and the upper cover filter screen 5 are both made of stainless steel, composite fiber, modified nylon or non-woven fabric materials; the filter fineness of dustcoat filter screen 4 is 4 ~ 10um, and the filter fineness of going up closing cap filter screen 5 is 1 ~ 4 um.

When in work, fuel flows from outside to inside and sequentially passes through the outer cover 1, the outer cover filter screen 4, the fiber particles 13, the upper sealing cover filter screen 5, the oil outlet hole 111 and the oil outlet 21; when the fuel oil passes through the outer cover filter screen 4, impurity particles larger than or equal to 4-10 um in the fuel oil are isolated outside the outer cover filter screen 4; when fuel passes through the fiber particles 13, due to the extremely strong filtering adsorption force of the microporous structure of the fiber particles 13, most of impurity particles of 1-4 um in the fuel are adsorbed on the fiber particles 13, and meanwhile, the marine organism fermentation liquid components in the fiber particles 13 are slowly released, so that colloidal substances which cannot be used for combustion in the fuel are decomposed and converted into combustible substances, and the quality and the combustion value of the fuel are improved; the residual impurities in the fuel oil are isolated outside the upper sealing cover filter screen 5; the filtered fuel flows out from the oil outlet hole 111 and the oil outlet 21.

Because the fuel oil is subjected to triple filtration of blocking filtration by the outer cover filter screen 4, adsorption filtration by the fiber particles 13 and blocking filtration by the upper sealing cover filter screen 5, the initial filtration efficiency of the filter element of the filter for filtering impurities larger than or equal to 4um can reach 99.9 percent.

this embodiment has still disclosed a filter, and this filter includes casing and above-mentioned filter element, and the filter element sets up in the casing, and the structure and the mounted position of other spare parts of filter are the same with prior art, do not do the perplexing here.

The embodiment discloses a method for manufacturing the fiber particles 13, which comprises the following steps:

Making paper pulp according to the prior art, uniformly mixing the paper pulp and the marine organism fermentation liquor according to a certain mass ratio (the preferred mass ratio is 1:1), and making a paper pulp mixture into spherical fiber particles 13 by means of a forming die; that is, in the paper making process, the mode of forming paper by paper pulp plane is changed, and the pulp mixture is formed into spherical particles by a mold. The fibrous particles 13 can be formed by a person skilled in the art with the aid of an auxiliary die according to a known paper making process, which will not be described in further detail herein.

The marine organism fermentation liquor (existing product) is explained in detail below; the marine microorganism fermentation liquor (also called as biofuel energy-saving agent) is prepared by extracting chitin derivative chitosan from marine organisms by using auxiliary enzyme, degrading to obtain-micro molecular chitosan as raw material, and fermenting, culturing and magnetizing the micro molecular chitosan, chitosan enzyme, lysozyme and the like. The marine microorganism fermentation liquor plays an important role in 'fuel oil biological enzyme', the fuel oil biological enzyme is developed on the basis of biological enzyme, contains a special microbial enzyme group, can target and catalyze the combustion reaction of a flame-retardant component in a fuel through an 'induction fit' effect, and an active group electron cloud of the fuel oil biological enzyme interacts with an electron cloud in a target molecule, so that the strength of a chemical bond of the fuel oil biological enzyme is weakened, the activation energy of the reaction is reduced, the fuel oil biological enzyme can be fully combusted in an extremely short piston stroke time, and the purposes of improving the grade of an oil product, improving the combustion efficiency of the oil product, improving the power of an engine and reducing the emission of pollutants are achieved.

The above description is of the preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification and improvement made within the spirit and principles of the present invention should be included within the scope of the present invention.
