Embodiment 1

[0024] The single fiber fineness is 3dtex, and the fiber length is 51mm PPS short fiber (Toray company Turkang fiber) to obtain a carded sliver through a woolen carding machine to make a fiber line, and then draw 4 of the prepared fiber lines, Obtain the roving that apparent fineness is 3.8Nm, carry out twisting again, make the roving that twist coefficient is 240, and its roving elongation is 29%, and the hairiness of roving surface hairiness length is 0.5~100mm accounts for 1 / 4 of the total amount of roving surface hairiness 60%; the above-mentioned roving is wound on the cylindrical body that the metal plate that the surface has small hole is made with cross helical shape, forms the filter layer that thickness is 2cm, obtains the winding type filter core of the present invention, and its outermost layer yarn and The angle of the porous aggregate axis is 60°. The filter element is used to filter the 85°C return water produced by the boiler, and the pressure loss is tested, a...

Embodiment 2

[0026] The single fiber fineness is 3dtex, and the fiber length is 51mm PPS staple fiber (Toray company Turkang fiber) to obtain a carded sliver through a woolen carding machine to make a fiber line, and then 2 of the prepared fiber lines are drawn, Obtain the roving that apparent fineness is 3.8Nm, carry out twisting again, make the roving that twist coefficient is 210, and its roving elongation is 25%, and the hairiness of roving surface hairiness length is 0.5~100mm accounts for the roving surface hairiness total number 80%; the above-mentioned roving is wound on the cylindrical body that the metal plate that the surface has small hole is made with cross helical shape, forms the filter layer that thickness is 2cm, obtains the winding type filter element of the present invention, and its outermost layer yarn and The angle of the porous aggregate axis is 65°. The filter element is used to filter the 85°C return water produced by the boiler, and the pressure loss is tested, an...

Embodiment 3

[0028] Using PPS short fibers with a single fiber fineness of 6dtex and a fiber length of 72mm to obtain a carded sliver through a woolen carding machine, and then drawing 6 of the prepared fiber threads to obtain an apparent fineness The roving of 1Nm is twisted again to obtain a roving with a twist coefficient of 220, its roving elongation is 25%, and the hairiness of roving surface hairiness length is 0.5~100mm accounts for 30% of the total number of roving surface hairiness; The roving is wound in a cross-helical shape on the cylinder made of a metal plate with small holes on the surface to form a filter layer with a thickness of 3 cm to obtain the wound filter element of the present invention, the outermost layer of yarn and the axis of the porous aggregate Angle 55°. The filter element is used to filter the 85°C return water produced by the boiler, and the pressure loss is tested, and the pressure loss is relatively low, specifically 0.4kg / cm 2 .

Abstract

The invention discloses a wound filter element and application thereof. The wound filter element comprises a porous aggregate and a rough yarn wound on the porous aggregate, wherein the rough yarn contains polyphenylene sulfide fibre, has a coefficient of twist of 180-280, has excellent bulkiness and better filtering property, and can not be excessively drafted during the winding. The wound filter element disclosed by the invention has the characteristics of small pressure loss, high filtering accuracy, and excellent steaming resistance and chemical properties, and can be applied to the field of filtration of various kinds of high-temperature liquids.

Description

technical field [0001] The invention relates to a winding filter element and its application, in particular to a winding filter element used in the field of high-temperature liquid filtration and its application. Background technique [0002] The wound filter element is a filter element for deep filtration, which is used for low-viscosity and low-impurity filtration. It is made of textile fiber thread, which is precisely wound on the porous aggregate according to a specific process. It has a honeycomb shape that is sparse on the outside and dense on the inside. Structure, forming numerous three-dimensional small holes, can effectively remove suspended solids, particles, rust and other impurities in the fluid, and has very good filtration characteristics. Widely used in the filtration of tap water, beverages, industrial water, domestic water, electroplating solution, chemical liquid, oil, paint, etc. [0003] Currently commercially available wound filter elements are mostly ...
