Embodiment Construction

[0017] The present invention will be described in detail below through specific examples.

[0018] An activated carbon air-conditioning filter element material and a preparation method thereof, which are made of the following raw materials in parts by weight (kg): sludge 130, corn stalks 15, peanut shells 18, zinc chloride 45, magnesium silicate 15, zirconia 8, ten Hexaalkyltrimethylammonium bromide 3, polyvinyl alcohol 3, zirconium fluoride 7, hydrotalcite 11, sepiolite powder 5, appropriate amount of distilled water;

[0019] A kind of activated carbon air-conditioning filter element material and preparation method thereof of the present invention, are made by following concrete steps:

[0020] (1) Air-dry the sludge from the sewage treatment plant under natural conditions, and then dry it in an oven at 110°C for 18 hours. After cooling, grind it into sludge particles with a particle size of 1-3mm for use;

[0021] (2) Dry the corn stalks and peanut shells in an oven at 80°...

Abstract

The invention discloses an active carbon air-conditioner filter core material and a preparation method thereof. The air-conditioner filter core material comprises the following raw materials, by weight part: 100-150 of sludge, 13-17 of cornstalk, 15-24 of peanut hull, 30-50 of zinc chloride, 13-16 of magnesium silicate, 6-9 of zirconia, 2-4 of cetyltrimethylammonium bromide, 2-3 of polyvinyl alcohol, 6-8 of zirconium fluoride, 8-12 of hydrotalcite, 5-6 of meerschaum powder, and a proper amount of distilled water. Zirconium fluoride, hydrotalcite, and meerschaum powder added in the air-conditioner filter core material greatly improve bactericidal activity, thermostability, and ion exchange performance of sludge active carbon, increase the adsorption capacity and adsorption range, and enlarge the application range of the adsorbent. According to the invention, the active carbon adsorbent is simple in preparation technology, wide in raw material source, low in cost, and excellent in performance, is good in use effect when taken as the air-conditioner filter core material, is less in change frequency, and has a long service life.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an activated carbon air-conditioning filter element material and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the increase of urban population and the strengthening of environmental protection awareness, the discharge of urban industrial wastewater and domestic sewage is increasing, the rate of urban sewage treatment is also increasing year by year, and the sludge generation rate of sewage plants is also increasing sharply. The sludge of the sewage treatment plant has a high water content, a large amount of organic matter, toxic and harmful substances, and semi-dry solid waste with complex rheology. It has a large capacity, is easily corrupted, unstable, and has a bad smell. cause serious environmental pollution. Activated carbon is a porous adsorption material with rich pore structure, high specific surface area and strong adso...
