Embodiment Construction

[0015] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] Such as figure 1 As shown, a high-efficiency PAP composite filter element provided by the present invention includes an outer layer of PP cotton 10, a middle layer of activated carbon 20, and an inner layer of PP cotton 30 rolled into a cylindrical shape. The three layers are in close contact; the outer layer of PP cotton 10 has a filtration accuracy greater than The filtering accuracy of the inner layer of PP cotton 30, the middle layer of activated carbon 20 is formed ...

Abstract

The invention relates to the technical field of water purification, and discloses a high-efficiency PAP composite filter element. The high-efficiency PAP composite filter element comprises outer-layerPP cotton which is rolled into a barrel, middle-layer activated carbon and inner-layer PP cotton; the filter precision of the outer-layer PP cotton is greater than that of the inner-layer PP cotton,and the middle-layer activated carbon is formed by pressing a plurality of carbon fiber stacks. The filter element achieves a tertiary filter effect, and can be compatible to existing water purifier filter bottles in markets, the number of pipes and the number of filter bottles in a water purifier are reduced, the full filter element only needs to be changed once, and water quality cannot be affected later.

Description

Technical field [0001] The invention relates to the technical field of water purification, in particular to a high-efficiency PAP composite filter element. Background technique [0002] Existing water purifiers on the market usually use a combination of three-stage independent filter bottle + filter element for filtration, and the filter element usually adopts a structure of PP cotton coated activated carbon particles and compressed activated carbon. The filter system of multi-stage filter element has disadvantages such as complicated pipeline and large space occupation, frequent filter element replacement, and carbon powder in the previous filter element is easy to precipitate and pollute the latter filter element. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency PAP composite filter element, which can achieve the effect of three-stage filtering with only one filter element, without multi-stage pipelines...
