Preparing method for air purifying agent for eliminating noxious gas and peculiar smells

Abstract

The invention relates to a preparing method for an air purifying agent for eliminating noxious gas and peculiar smells. The preparing method includes the steps that water, an acid-base adjusting agent, a dispersing agent and an antifoaming agent are added into a high shearing device in the certain proportion and stirred to be even, an astringing agent and a photocatalyst are added into the high shearing device filled with the water, the acid-base adjusting agent, the dispersing agent and the antifoaming agent in the certain proportion, the mixture is highly sheared, shearing is carried out for the certain time, then a surfactant is added, packaging is carried out, and then the air purifying agent for eliminating noxious gas and peculiar smells is obtained. The air purifying agent can be used under the conditions that light exists and light sources are not allowed condition, and the effect is optimum under the condition that light exists.

Description

technical field [0001] The invention relates to a preparation method of an air purifier capable of removing harmful gas and peculiar smell. Background technique [0002] At present, air purifiers are divided into two types, one is the purifier that uses its own fragrance to cover up the odor, and the other is the purifier that uses adsorption or chemical reaction to absorb or degrade harmful gases. The first one is just to cover up the odor, and does not remove the harmful gas itself; and the second one is currently divided into two types in the market, one is the traditional adsorption principle of activated carbon for adsorption. This method only absorbs the harmful gas, but does not completely remove it. The adsorbent needs to be replaced after the adsorption is saturated; the other is a new type of photocatalyst. Under the irradiation of light, the valence band electrons of the nano photocatalyst are excited to the conduction band, forming electrons and holes, which in...

The first one is just to cover up the odor, and does not remove the harmful gas itself; and the second one is currently divided into two types in the market, one is the traditional adsorption principle of activated carbon for adsorption. This method only absorbs the harmful gas, but does not completely remove it. The adsorbent needs to be replaced after the adsorption is saturated; the other is a new type of photocatalyst. Under the irradiation of light, the valence band electrons of the nano photocatalyst are excited to the conduction band, forming electrons and holes, which interact with O2 and H2O adsorbed on its surface. , to generate superoxide anion free radicals, O2- and hydroxyl radicals -OH, whose free radicals have a strong ability to oxidize and decompose, and can destroy C-C bonds, C-H bonds, C-N bonds, C-O bonds, O-H bonds, and N-H bonds in organic matter key, decompose organic matter into carbon dioxide and water; at the same time destroy the cell membrane of bacteria and solidify the protein of virus, change the living environment of bacteria and virus to kill bacteria and virus. Although this kind of method can remove harmful gas, it must be used with light Exist, the use is subject to certain restrictions
