Abstract

The invention discloses a preparation method of a biomass filtering and purifying filter material and a use method thereof. The preparation method comprises the following steps of using crop straw and agricultural and forestry wastes as raw materials; crushing, screening, soaking, cleaning, whitening, loosening, rinsing, whitening, drying, and the like, so as to prepare the biomass filtering and purifying filter material. The biomass filtering and purifying filter material has the advantages that the biomass is whitened and loosened, so that multiple fine gaps in a biomass fiber structure are loose, impurities in a filtering matter are effectively contained, and the flowing drag on the filtering matter is reduced; the filtering property is good; by utilizing the particular physical structure, the corresponding additive is added to act on the filtering matter according to different function requirements of the filtering matter, so that the expected requirement and effect are reached; the biomass filtering and purifying filter material provided by the invention has the characteristics that the application range is wide; and is convenient to be processed into various filtering devices for purifying gas and liquid.

Description

Technical field [0001] The invention relates to the technical field of filter materials, in particular to a preparation method and a use method of a biomass filter purification filter material. Background technique [0002] In the filtering operation, various porous materials used to intercept the alternative filtered substances contained in the fluid and retain the impurities are called filtering materials. The commonly used filter materials in industry are: ① Woven materials, filter cloth and filter screens woven from natural or synthetic fibers, metal wires, etc., are the most commonly used filter media in industrial production. Such materials are cheap, easy to clean and replace, and the minimum particle size that can be retained is 5 to 65 μm. The single-strand filter made of polyamide, polyester or polypropylene fibers has uniform texture, corrosion resistance and fatigue resistance, and is gradually replacing other fabric filter cloths. But this kind of material cannot a...
