Description
Technical field:
This utility model belongs to the air purifier technical field, relates in particular to a kind of manufacture technology field of multifunctional air purifier.
Background technology:
The source of room air pollution comprises multiple materials such as dust, fiber, foreign odor, abnormal flavour and antibacterial, virus, but the harm of health mainly is the pellet of indoor suspension.This is because cause the microorganisms such as antibacterial, spirillum, virus of health infringement, although its size only between 0.01 to 10 micron, they can not individualism in air, is everlasting than the particulate matter surface adsorption of they big several times.Traditional air purifier makes air pass porous filter material (materials such as non-woven fabrics, filter paper, fiber or foam filter material) by pressure fan, thereby pollutant are separated from air, reach the purification purpose, perhaps make in the air pollutant electrically charged, utilize dust collect plant to capture charged particle and reach the purpose that purifies air by corona discharge.But utilize physical filtering, absorption, static to condense the depurator of simple functions such as removing dust or comprehensive function on this class market, although it is effective to a certain extent, but just play the transfer of pollutant, can not fundamentally be eliminated the pollution that odor smell, pathogen, virus, microorganism etc. cause.
At present, second filial generation product the first three years of air purifier comes into the market, and it is to be the air purifier of major function with ozone, anion.Ozone has sterilization, sterilization, deodorant to taste and goes functions such as paint pigment.Therefore, utilizing ozone to combine with the smoke abatement and dust control of anion and the method for other advanced physical filterings or removal dust, is current comparatively ideal air purifier.But when ozone concentration reaches 0.15PPM, will produce injurious effects to human body, so general using ozone is when carrying out indoor sterilization processing, personnel should not be in indoor activity.
Present state-of-the-art air purifier is that a kind of smoke elimination, dedusting, sterilization and disinfection, deodorant to taste, decomposing organic pollutant of collecting is in photocatalysis air purifying device together.This type of air purifier is different from first generation physical air purifier and second filial generation ozone, negative ion type air purifier.Its treatment facilities is sterilization light and deodorize disinfection filtering net, have the effect of sterilization, sterilization, taste removal, dedusting simultaneously concurrently, the hydroxyl radical free radical ion is direct sterilization, disinfectant chemical substance, it directly decomposes Organic substance, antibacterial is destroyed cell membrane earlier, Organic substance in the decomposer directly solidifies its protein to virus again, and end product is CO
2And H
2O.Nano-photo catalytic is can realize regenerating voluntarily with respect to the superiority of normal optical catalyst article, and percent reduction greatly improves, and hydroxyl radical free radical ion itself is nontoxic, does not decompose, and does not overflow, and more can not produce toxin.After testing, this technology can effectively be killed nearly ten kinds of common pathogenic bacterias, and is all effective to pulmonary tuberculosis virus, influenza virus, hepatitis B virus and SARS virus.Photocatalysis is a kind of high-tech product, function with decomposing organic pollutant, photocatalysis and plasma dedusting coupling, the small amount of ozone that makes the plasma dedusting produce enters photocatalytic reaction device, accelerate light and swashed the effect right separation in electronics one hole of catalyst surface generation down, thereby improved the efficient of depurator decomposing organic pollutant, sterilization and deodorization etc.Go the cigarette method to combine with the dedusting of some physics so again, thereby become a kind of comprehensive, multi-functional air purifier.
