Problems solved by technology

[0002] At present, there are chemical adsorption and physical adsorption methods for the treatment of harmful gases. The more common chemical adsorption is the activated alumina material loaded with potassium permanganate, with alumina as the carrier and potassium permanganate as the active material, but the high Potassium manganate itself is corrosive and irritating to tissues. It is easy to pollute the skin and cause black, oral mucosa black staining, gastric bleeding, liver and kidney damage, etc. The lethal dose of potassium permanganate is about 10 grams.
Physical adsorption is mainly represented by activated carbon and its derivative products. However, activated carbon is flammable and is a dangerous product, and it carries a large amount of black dust, which will pollute the indoor and vehicle environment and bring safety hazards
[0003] Existing air purifiers mainly use ozone purification technology, negative ion dust removal technology and high-voltage electrostatic technology. Ozone technology has sterilization and deodorization effects, but the removal efficiency of organic pollutants is low; in addition, ozone itself is harmful to the human body and the environment
Negative ions and high-voltage electrostatic technology are physical effects that can remove smoke and dust in the air, but cannot remove and purify pollution caused by chemicals, biology, and microorganisms
In the structure of the air purifier product, the activated carbon filled inside is responsible for the main function of absorbing formaldehyde. However, because the activated carbon itself has an adsorption saturation value, and there is no change before and after adsorption, users cannot make a correct identification, and the electronic components are inconvenient to disassemble and replace. , over time, the product becomes an ornamental item purchased at a high price

Abstract

The invention relates to an inorganic silicon nanometer adsorbent for adsorbing toxic and harmful gas (formaldehyde, ammonia, benzene, TVOC and the like), peculiar smells and moisture in air and a preparing method thereof. The adsorbent is prepared from, by mass, 0.020% to 0.024% of Fe2O3, 0.11% to 0.15% of Al2O3, 0.022% to 0.026% of CaO, 95.10% to 95.30% of SiO2 and the balance loss on ignition. The specific area of the adsorbent is 200 m<2> / g to 2,000 m<2> / g, the average pore size is 0.5 nm to 20 nm, and the total pore volume is 0.1 ml / g to 10 ml / g. The adsorbent has the advantages of being stable in chemical property, high in adsorption performance, good in heat stability and high in mechanical strength.
