Problems solved by technology

Disadvantages: Activated carbon has large pores, it is difficult to achieve fine filtration, and it cannot filter out micron and nanoscale substances, and is often used for coarse filtration
[0009] Disadvantages of microporous membrane filtration: Compared with nanoporous membranes, the diameter of the filtration holes on microporous membranes is still too large. Although it can meet many fine filtration requirements in daily industry and life, it cannot be used to filter extremely small substances. Such as blood purification, virus separation in protein, ion filtration in liquid, super purification of water, etc.
[0012] Similar to microporous membrane filtration, the disad

Abstract

The invention relates to a novel tree type nano cylindrical hole filtering membrane with 15 branch holes and used for liquid-liquid separating. The novel tree type nano cylindrical hole filtering membrane with the 15 branch holes and used for liquid-liquid separating is characterized in that a plurality of uniformly-distributed tree shaped structural cylindrical through holes are formed in one layer of solid materials, wherein each through hole comprises a big trunk hole, and fifteen small branch holes which are parallel to the trunk hole and completely communicate with the trunk hole; the surface material of the trunk hole is the same as the surface materials of the branch holes; each branch hole is a filtering hole, and the length of each branch hole is determined based on the filteringhole strength requirement; the trunk hole is used for decreasing the flowing resistance of the filtering membrane; the physical adsorption between one type of liquid in a liquid mixture to be separated and the surface of the trunk hole is weak, and the physical adsorption between the rest liquid and the surface of the trunk hole is strong; the radius of each branch hole is Rb,1=(0.1-0.2)Rcr, wherein Rcr is the radius of critical cylindrical hole through which liquid, with weak physical adsorption relative to the surface of the trunk hole, in the liquid mixture can be used as a continuous medium for flowing; and the solid material in the layer is treated as the filtering membrane.

Description

technical field [0001] The invention relates to the field of filter membranes, in particular to a novel tree-shaped nano-scale cylindrical pore filter membrane with 15 branch holes for liquid-liquid separation. Background technique [0002] Membrane for filtration, referred to as filter membrane, has important applications in industry and daily life. It can be used to filter out solid particles and impurities, purify liquids, and also to filter out bacteria and macromolecules, or to realize the separation of two liquids. separate. In daily life, filter membranes can be used to purify drinking water and various beverages, and can also be used to filter out impurities and various ions in seawater to achieve seawater purification. The existing commonly used filtering methods and means are: [0003] 1. Activated carbon filtration [0004] Activated carbon is an industrial adsorbent with a wide range of uses. It uses charcoal, various fruit shells and high-quality coal as raw ...
