Two-in-one paper fiber powder activated carbon filter element and preparation method thereof

Abstract

A two-in-one paper fiber powder activated charcoal filter element comprises at least three filtering layers which are in sleeve joint coaxially and tightly, the three layers sequentially comprise an inner layer, namely a PP (Propene Polymer) filter element which is tubular, an intermediate layer, namely a two-in-one paper fiber powder activated charcoal kryptol which is tubular and sleeved outside the PP filter element, an outer layer, namely a fixed protective layer sleeved outside the two-in-one paper fiber powder activated charcoal kryptol, as well as an end cover which is used for sealing the two ends of each filtering layer of two-in-one paper fiber powder activated charcoal filter element, from inside out. According to the invention, paper fiber is taken as main raw material, activated charcoal powder is added, the advantage of strong adsorbability of activated charcoal powder and the character of branching and tangling of the paper fiber are utilized in a combined manner, and the defects of reeled winding form and incapability of resisting long time soaking in the prior art can be overcome.

Description

technical field [0001] The invention relates to a product and a preparation method for drinking water and other clean water purification, medicine, brewing, food decolorization, organic solvent adsorption and filtration, in particular to a filter element and filter element combining paper fiber and activated carbon powder method of preparation. Background technique [0002] In liquid, whether it is industrial production, electroplating solution, food, beverage, water, or household water, it must be kept clean. As the liquid is polluted during processing, or chlorine gas is added to tap water treatment, disinfection water will affect processing. hazardous to health. Therefore, most of them use activated carbon filter elements to absorb excess organic matter in the liquid to achieve the effects of purification, decolorization, and deodorization. [0003] (Paper fiber powder activated carbon) has a very large (surface area) and strong adsorption, decolorization, and odor remo...

AI Technical Summary

Problems solved by technology

[0005] One of the purposes of the present invention is to provide a new filter element material, that is, a two-in-one paper fiber powder activated carbon carbon rod, which can overcome the disadvantages of the old paper fiber powder activated carbon filter products that are not durable and have a short service life.
