preparation example Construction

[0040] A preparation method of composite air purifier, comprising the following steps:

[0041] 1) Preparation of component I: take a non-polar carrier, add it to the active component A solution, soak and filter to obtain a carrier loaded with active component A; let the carrier loaded with active component A stand until there is no liquid drop out, then dry and cool naturally to obtain component I;

[0042] 2) Preparation of component II: take the polar carrier, add it to the solution D containing the active component B and the accelerator C, and after impregnating and filtering, obtain the carrier loaded with the active component B and the accelerator C; The carrier of Component B and Accelerator C is allowed to stand until no liquid drips out, and after drying and natural cooling, Component II is obtained;

[0043] 3) Compounding: According to the proportioning ratio of the formula, component I and component II are evenly mixed in a certain proportion to obtain the composi...

Abstract

The invention discloses a compound air purifier. The compound air purifier is prepared by compounding a component I and a component II at the weight ratio of 1: (1-8), wherein the component I comprises a nonpolar carrier and an active component A loaded to the nonpolar carrier, the specific surface area of the nonpolar carrier is greater than 200m<2>/g, and the pore volume of the nonpolar carrier is greater than 0.1cm<3>/g; the active component A is strong alkali, permanganate or ferrate; the component II comprises a polar carrier as well as an active component B and an accelerant C loaded to the polar carrier, the specific surface area of the polar carrier is greater than 200m<2>/g, and the pore volume of the polar carrier is greater than 0.15cm<3>/g; the active component B is permanganate or ferrate, and the accelerant C is soluble salt of silver, soluble salt of golden, soluble salt of platinum, or soluble salt of palladium. The invention further discloses a preparation method of the compound air purifier, and an air purifying device comprising the compound air purifier. The compound air purifier provided by the invention has good purifying effects and sterilizing effects for various contaminants, and can work under high air speed.

Description

technical field [0001] The invention relates to the fields of environmental protection treatment and air purification, in particular to a composite purifying agent for air purifying, a preparation method thereof and an air purifying device. Background technique [0002] Indoor air pollution is threatening human health, especially the volatile harmful gases such as aldehydes and benzenes contained in new houses, new cars and new furniture. [0003] Formaldehyde is a colorless irritating gas and is one of the common pollutants in the air indoors and in cars. It often exists in plywood containing urea-formaldehyde resin, including particle board, hardwood plywood paneling, and medium-density fiberboard. The latter has the highest formaldehyde content. Formaldehyde is irritating to the eyes and nose, and long-term exposure may induce cancer. [0004] Benzene, xylene and other benzene series are volatile organic compounds. They are colorless and have a special aromatic smell. Th...
