技術簡介

本發明提供一種過濾結構，包括：一第一多孔層，具有多數個第一孔洞；以及一第二多孔層，位在該第一多孔層上方，且具有多數個第二孔洞，其中該些第二孔洞的尺寸小於該些第一孔洞的尺寸。該過濾結構可藉由壓擠等簡易省能的方式排出水分。

Abstract

The invention provides a filter structure. A second porous film having a plurality of second holes is disposed on a first porous film having a plurality of first holes. The second holes are smaller than the first holes. The filter structure has excellent venting efficiency and avoids the problem of having blocked holes as a result of filtrated residue. The filter structure can also be dried by an easy and power-saving method such as compression. The invention also provides a method for filtration. The above-mentioned filter structure is provided. A mixed solution drifts down onto a top surface of the second porous film of the filter structure. Residues larger than the second holes in the mixed solution are intercepted, and a liquid in the mixed solution passes through the second holes and keeps flowing down.
