High-efficiency filter element for water purification equipment and preparation method thereof

Abstract

The invention belongs to the field of non-woven material preparation, and relates to a high-efficiency filter element of water purification equipment and a preparation method thereof. The invention uses solid powder modified particles to modify the melt-blown fiber web twice, and the first modification applies The solid powder modified particles are mainly distributed on the surface of the melt-blown fiber web, and the solid powder modified particles applied for the second modification are mainly distributed in the middle of the melt-blown fiber web. Both the surface and the inner core of the blown fiber web have a suitable content of solid modified particles. In the first modification process, the surface of the melt blown fiber web still retains a certain degree of adhesion and adhesion, and then with the help of a strong solid The fluidized bed spraying device with powder spraying ability can improve the adhesion firmness of solid powder modified particles and fibers, and the solid powder modified particles are not easy to fall off, reducing the frequency of replacing filter elements and reducing the cost of water purification equipment.

Description

technical field [0001] The invention belongs to the field of nonwoven material preparation, and in particular relates to a high-efficiency filter element of water purification equipment and a preparation method thereof. Background technique [0002] As people's hygiene requirements for drinking water are getting higher and higher, water purifiers are used more and more widely in various occasions (such as homes, businesses, and some entertainment venues, etc.), and traditional reverse osmosis water purifiers need pre-assembly Install the filter element and the reverse osmosis filter element, the filter element assembly is generally a filter bottle with a filter element, or a filter bottle with multiple pre-filter elements. [0003] Chinese patent CN201911224557 discloses a large flux four-in-one filter element structure, including a filter bottle, a filter bottle cap, a water guide cylinder, a PP composite filter element, a reverse osmosis filter element, a PP upper end cap,...

AI Technical Summary

Problems solved by technology

In actual use, the main purification and interception functions are the second-stage filter element and the third-stage filter element, and the replacement cycle of the second-stage filter element and the third-stage filter element is short and expensive, and the second-stage and third-stage filter elements are frequently replaced. It will lead to high cost of water purification equipment, which will make water purification equipment unacceptable by consumers
