Embodiment 1

[0038] (1) mineral processing step: select attapulgite to have the pure natural mineral material concentrate with adsorption capacity, and the content is more than 60%;

[0039] (2) Purification step: the selected natural mineral material is purified, and attapulgite is pulverized to 325 orders;

[0040] (3) modification, activation step: by the appropriate proportioning of the weight of natural mineral material after the proportioning of purification, wherein the weight percentage of attapulgite after the proportioning is 76%, the weight percentage of artificial zeolite molecular sieve is 20%, after purification The attapulgite is added with a surfactant, and the weight percentage of the surfactant dodecyldimethylbenzyl ammonium bromide is 0.5%, and the temperature is controlled at 50°C to activate and expand the pores; then weigh 0.5 % sodium carbonate or sodium chloride or sodium fluoride or sodium bisulfite and 1% ammonium bicarbonate or sodium bicarbonate or aluminum sulf...

Embodiment 2

[0050] In Example 2, the steps of beneficiation, purification, modification, activation, primary drying, primary granulation, secondary drying, secondary granulation, tertiary drying, roasting, sieving and finished product testing and packaging are the same as in Example 1, with different What is more is that the weight percentage is attapulgite 47%, artificial zeolite molecular sieve 49%, temperature is controlled at 80 ℃ and carries out activation expansion; Wherein attapulgite, artificial zeolite molecular sieve, dodecyl dimethyl benzyl ammonium bromide , sodium carbonate or sodium chloride or sodium fluoride or sodium bisulfite and ammonium bicarbonate or sodium bicarbonate or aluminum sulfate, nano photocatalyst titanium dioxide powder and nano air catalyst titanium dioxide powder is 100%.

Embodiment 3

[0052] In embodiment 3, the packing steps including ore dressing, purification, modification, activation, primary drying, primary granulation, secondary drying, secondary granulation, tertiary drying, roasting, sieving and finished product testing and packaging are the same as in Example 1, with different It is 57% by weight of attapulgite, 33% by weight of artificial zeolite molecular sieve, 2% by weight of surfactant dodecyldimethylbenzyl ammonium bromide, and 2.5% by weight Sodium carbonate or sodium chloride or sodium fluoride or sodium bisulfite with 2.5% ammonium bicarbonate or sodium bicarbonate or aluminum sulfate and weigh 2% nano photocatalyst titanium dioxide powder material and 1% nano air catalyst titanium dioxide powder material, and the temperature is controlled at 65°C for activation and hole expansion; among them, attapulgite, artificial zeolite molecular sieve, dodecyldimethylbenzyl ammonium bromide, sodium carbonate or sodium chloride or sodium fluoride or su...

Abstract

The invention provides a composite air purificant containing nanometer mineral matters, which contains 47wt% to 78wt% of attapulgite as a natural mineral, 20wt% to 50wt% of synthetic zeolite molecular sieve as a molecular sieve, 0.5wt% to 5wt% of sodium carbonate or sodium chloride or sodium fluoride or sodium hydrogensulfite as a modifier, 0.5wt% to 5wt% of ammonium bicarbonate or sodium bicarbonate or aluminum sulfate as a foaming agent, 0.5wt% to 2wt% of dodecyldimethylbenzylammonium chloride as a surface active agent, 0.2wt% to 2wt% of nanometer photocatalyst titanium dioxide colloidal solution as a photocatalyst and 0.1wt% to 1wt% of nanometer aircatalyst titanium dioxide colloidal solution as photochemical catalysts. The composite air purificant is prepared by first drying, first pelleting, second drying, second pelleting, third drying, baking and finish product detection and package. The invention has high alternative adsorbability and high decomposition efficiency for organic pollutants in the air.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to the production of a composite air purifier containing nano-minerals by selecting natural mineral materials and photocatalyst materials and adopting a semi-dry method for modification and activation and a preparation method thereof. Background technique [0002] According to the report provided by the World Health Organization, the number of premature deaths due to urban pollution in the world has exceeded 750,000, including 530,000 in Asian countries and regions. The number of people suffering from air pollution is even more numerous. At present, the problem of air pollution in my country's cities is still prominent. The ambient air quality of 44.9% of cities is lower than the national second-class standard, and 43 cities' ambient air quality is lower than the national third-class standard. According to experts, 30% of the world's new and reconstructed buildi...
