Method for removing indoor air contaminations based on synergistic action of negative ion generator and mixed medium

Abstract

The invention discloses a method for removing indoor air contaminations based on the synergistic action of a negative ion generator and mixed medium, which is realized by the joint action of a negative ion generator module and a cellular mixed medium module. According to the method, the negative ion generator module generates negative ions and ozone, and the cellular mixed medium module is filled with the mixture of modified active carbon and a catalyst; the modified active carbon is modified by using alkali, acid, or a metal and a metal oxide according to different contaminations; the catalyst is an oxide of a noble metal or a transition element metal; when contaminated gas passes through, gaseous contaminations are degraded under the chemical action of ozone, the modified active carbon and the catalyst, ozone is catalyzed to be degraded, and air reaching an outlet contains negative ions, so that the content of ozone is greatly reduced, and air is fresh and pollution-free, and is safe in use. The method disclosed by the invention is applied to air purification of an indoor air purifier or an air-conditioning system.

Description

technical field [0001] The invention relates to a method for removing indoor air pollutants by a negative ion generator in cooperation with mixed media, and belongs to the technical field of indoor air purification. Background technique [0002] With the aggravation of indoor decoration pollution and outdoor air pollution, various volatile organic compound gases (such as toluene, formaldehyde) and harmful inorganic gases (such as SO 2 , NO 2 ) is also increasing, threatening people's health. [0003] Negative ions, ozone, modified activated carbon, and catalytic decomposition are all purification technologies for indoor air. Negative ions can not only remove smog and dust in the indoor air by making the particle nuclear power form large ions, but also neutralize the positive ions in the air, activate the air, help the human body restore normal balance, promote growth and development, and prevent diseases. The generation of negative ions is often accompanied by the generat...

Problems solved by technology

[0004] Since the generation of negative ions is often accompanied by the generation of ozone, ozone exceeding the safety standard is harmful to human health, so most of the current negative ion generators focus on how to reduce the concentration of ozone while increasing the concentration of negative ions, so that the purification effect of ozone cannot be utilized; At present, there are still some negative ion generators that use the negative ions and ozone generated by the generator to purify the air together, but they do not consider the control of ozone concentration, which will be harmful to human health; in addition, although the technology of ozone decomposition catalyst purification is gradually mature, it will Its combined application with negative ion generator and modified activated carbon has not been reported
