Abstract

The invention discloses a pure gas-gathering tower type spherical diatomite particle purifying adsorbent and a preparation method thereof. The adsorbent comprises, by weight, 50-70 parts of diatomite mesoporous nano materials, 7-12 parts of tourmaline, 10-20 parts of MOFs grapheme composite materials, 5-10 parts of sepiolite, 5-8 parts of negative ion powder, 3-5 parts of far-infrared ceramic powder, 15-20 parts of Sesbania cannabina powder and 7-12 parts of nano-photocatalyst. The adsorbent is high in adsorption capacity, good in purifying effect and long in service life.

Description

technical field [0001] The invention belongs to the technical field of environmental protection materials, and in particular relates to a spherical diatom pure gas-gathering tower particle purification adsorbent and a preparation method thereof. Background technique [0002] Air disinfection and purification are of great importance to human health. The air often contains organic or inorganic substances harmful to human health such as viruses, bacteria or other pathogens, as well as formaldehyde, organic solvents and ammonia. Viruses and bacteria in the air are often killed by spraying peracetic acid, chlorine dioxide, or boiling vinegar, Chinese herbal medicine, or using ozone, or using ultraviolet radiation, and also commonly used methods such as activated carbon adsorption for air purification. [0003] At present, the purification products on the market are mainly activated carbon and bamboo charcoal. Due to the low porosity and large pore size of these products, the ads...
