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
The present invention relates to a kind of anion generator and work in coordination with the method that mixed-media removes indoor air pollutants, belong to Techniques for Indoor Air Purification field.
Background technology
Along with the aggravation of the phenomenons such as interior decoration pollution, outside atmosphere pollution, the various volatile organic compound gases (as toluene, formaldehyde) in room air and harmful inorganic gas are (as SO
2, NO
2) also increasing, threaten the health of people.
Anion, ozone, modified activated carbon, catalytic decomposition are all the purification techniques for room air.Anion not only removes smog, dust in room air by making particle nuclear power form heavy ion, more can in and cation in air, activating air, helps human body to recover normal balance, enhancing development and prevent disease.The normal generation with ozone in anion generating process, ozone itself has stronger oxidisability, has good effect in removal organic gaseous contamination object space face.Modified activated carbon purification techniques, by some physics, chemical treatment, or change the structure of activated carbon surface micropore, or change the content of its surface acidic-basic property and some functional group, active carbon is made to have certain special absorption property characteristic, to there being comparatively ripe application in the purification of gas pollutant.
Due to the generation with ozone normal in anion generating process, the ozone exceeding safety standard is detrimental to health, therefore current anion generator pays close attention to how while increase negative ion concentration, to reduce ozone concentration mostly, and the catharsis of such ozone just could not be used; The anion that some anion generator current utilizes generator to produce and ozone purify air jointly, but do not consider the control to ozone concentration, like this can be unfavorable to health; In addition, though the technology of ozone decomposition catalyst purification is ripe gradually, by not appearing in the newspapers of itself and anion generator and modified activated carbon connected applications.
Summary of the invention
For overcoming above-mentioned defect, the invention discloses a kind of anion generator and working in coordination with the method that mixed-media removes indoor air pollutants.The method make use of on the one hand anion that anion generator produces and ozone purifies air, make use of modified activated carbon again on the other hand, itself and ozone is made jointly to decompose dusty gas, in addition, also utilize catalyst, promote decomposition reaction, the more important thing is and decompose unnecessary ozone, ensure the security of purification techniques.
Technical solution of the present invention is achieved in that
Anion generator works in coordination with the method that mixed-media removes indoor air pollutants, is realized by anion generator module, cellular mixed-media module acting in conjunction; The described filling-modified active carbon of cellular mixed-media inside modules and the mixture of catalyst; Dusty gas first produces anion and ozone through anion generator module, then by cellular mixed-media module, ozone is after cellular mixed-media catalytic decomposition, make the air in arrival exit with anion, pure and fresh, pollution-free, and ozone free, use safety.
Further, in described cellular mixed-media module, modified activated carbon, for different pollutants, selects alkalescence or acid or metal and metal oxide to do modification.
Further, in described cellular mixed-media module, catalyst is the oxide of noble metal or transitional metal element.

Further, described noble metal is palladium, platinum.
Further, the oxide of described transitional metal element is the oxide of Mn, Cu.
When dusty gas passes through, organic pollutant, under the oxidation of ozone and the catalytic action of catalyst, is finally broken down into innocuous substance, as follows to the cutting mechanisms of organic pollutant toluene.
Under the oxygen of inorganic pollution gas in modified activated carbon and air, steam effect, be decomposed into salt and water, to inorganic pollution gas SO
