Problems solved by technology

However, the function of the current filter material is relatively simple, the production process is relatively complicated and the production cost is relatively high, and the current filter material has relatively poor adsorption capacity, and the impurity in the filter material is generally filtered by blocking, so the filtration efficiency is relatively low
[0003] At present, no filter substrates made of plant stems, rods, and leaves have been retrieved

Abstract

The invention discloses a plant filter base material which is prepared by the working procedures of crushing, screening, degreasing, washing, softening, cleaning, puffing and drying a mixture of plant stems and leaves, and the like. According to the filter base material disclosed by the invention, plants are puffed, so that the fiber structure of the plants is fluffy to form a plurality of small gaps, the flow resistance to filter media is reduced, and impurities in filtered substances are effectively intercepted. According to the filter base material, a surface barrier form of a traditional filter material is converted into a volume type echelon filter and deep adsorption form. Additionally, the filter base material disclosed by the invention is in a fluffy structure, so that various additives can be steadily stored in the structures and cell capsules of plant fibers so as to be processed into various gas and liquid filter materials. When the filter media pass through the filter materials, the plant fibers are extruded, so that the additives are slowly released to repair the filter media, and the adverse effect caused by excessive release of the additives can be avoided.

Description

technical field [0001] The invention belongs to the technical field of filter materials, and in particular relates to a plant filter base material. Background technique [0002] In the filtration operation, various porous materials used to intercept the solid particles contained in the fluid and support the filter cake are filter materials. Commonly used filter materials in industry are: ①Woven material, filter cloth and filter screen woven from natural or synthetic fibers, metal wires, etc., is the most commonly used filter medium in industrial production. This type of material is cheap, easy to clean and replace, and the minimum particle size that can be retained is 5-65 μm. Single-strand filter screens made of fibers such as polyamide, polyester, or polypropylene are uniform in texture, corrosion-resistant, and fatigue-resistant, and are gradually replacing other fabric filter cloths. But this kind of material can't absorb the impurities in the filtered material, it's j...
