Description

A kind of air purifier

Technical field

The utility model relates to a kind of small household appliances, and in particular to a kind of air cleaning unit that can remove formaldehyde etc..

Background technology

Air purifier is the small household appliances product for purifying the air of a room, and is mainly solved due to finishing or other originals The air pollution problem inside rooms because caused by.The characteristics of having persistence and uncertainty due to the release of indoor air pollutants, Therefore it is the method for internationally recognized improvement IAQ to be purified the air of a room using air purifier.

There are various different technologies and medium in air purifier, enable it to provide a user with the sky of cleaning and safety Gas.Conventional air purifying process has：

1st, active carbon adsorption technology

Activated carbon application is administered in finishing pollution, and activated carbon is prepared using advanced boring technique, it is possessed and interior The pore structure that pernicious gas molecular size matches, is exclusively used in formaldehyde adsorption, benzene homologues, ammonia, radon etc. all harmful Gas and air in planktonic bacteria.With inhale taste, detoxification, it is deodorant, dry, it is mould proof, sterilized, purification etc. comprehensive function, have Effect removes indoor environmental pollution, is successfully applied to finishing pollution improvement.Advantage：Adsorption capacity is very strong, can effectively in adsorption chamber Harmful substance in air.Shortcoming：Activated carbon can only be adsorbed temporarily, and be raised with temperature, wind speed, and the pollutant for being adsorbed is just Separate out is possible to, so often to change filtering material, it is to avoid adsorption saturation.

2nd, negative aeroion

Negative aeroion can reduce the polluter from air, reduce harm of the excessive active oxygen to human body, make air It is purified, advantage：Second-hand-cigarette pollution effects significantly can simultaneously be used effect dedusting by negative oxygen ion clarifier, promote human body new old generation Thank and improve the health care of sleep, while discharging drop ozone has certain sterilizing.Shortcoming：The life-span is very short in atmosphere for negative oxygen ion, institute It is very general to other pollution clean-up effects to need sustained release.

3rd, electrostatic precipitation technology

Electrostatic precipitation is using the principle absorption bulky grain of high-pressure electrostatic absorption, advantage：Efficiently remove the particulate in air Pollutant, such as dust, coal smoke, pollen, cigarette taste and kitchen fume etc..Simultaneously also effectively absorption air in gaseous contaminant and Filter the pathogenic tiny organism in air.Shortcoming：Easily produce ozone.

4th, UV radiation technology for sterilization

UV radiation technology for sterilization is to irradiate material using ultraviolet, makes the microbial cell kernel protein molecular of body surface Construction changes and causes death.Due to ultraviolet penetrability difference, generally ultraviolet irradiation is mainly used as bakery and confectionery car Between, the surface of equipment, packaging material and water it is sterilized.Advantage：It is sterilized efficiently rapid, when air is by irradiating, in air Microorganism is just killed rapidly；Shortcoming：Ultraviolet can produce very big nocuity to the skin of human body.

5th, photocatalyst technology

Also referred to as cold catalyst technology, its operation principle is that nm-class catalyst is plated on specific carrier, is made Filter screen, by fan action, under the ultraviolet irradiation of specific wavelength, makes catalyst that Strong oxdiative occur with pernicious gas and reacts, Solidification virus protein, suppresses virus activity, so that purify air.Persistently, stable chemical nature, hardness is high for photocatalysis, Price is low, harmless.But, the condition that the technology is realized in itself is harsher, the practical application in air purifier There is larger gap compared with efficacy in laboratory.

Advantage：Photocatalysis technology has the practicality effect of broad spectrum activity, and purification efficiency is higher.Shortcoming：Photocatalyst must be Competence exertion effect under ultraviolet irradiation.If solar irradiation can not be obtained, want to activate photocatalyst again, then must add in addition Uviol lamp launches ultraviolet, so being fitted with uviol lamp in general smell photocatalysis purifier（Wavelength in 254nm or 365nm）.But excessive ultraviolet has injury to human body, so to avoid ultraviolet lamp exposed.

In interior, such as home environment, pollutant is mainly the formaldehyde of art work generation, dust etc., the formaldehyde in house ornamentation Incubation period is 3 to 5 years, and even more long, and pet and body hair, scurf, second-hand flue dust etc. are also not allow what is eliminated；And in work Make in environment, the chemical contamination that all kinds of machines are brought is also extremely serious；

Active carbon adsorption power is stronger, and surface area is very big, and it is all effectively, but PARA FORMALDEHYDE PRILLS(91,95) etc. to many pernicious gases The effect very little of organic matter, and be very easy to saturation, once saturation, purification filtering material in itself again can become pollution sources.

Negative oxygen ion can not only purify air, and air quality can be improved, using wide.But produce negative oxygen from While sub-, a large amount of ozone and negative Nitrogen ion, excessive concentration are also easily produced, will result in secondary pollution.Using ozone technology Air purifier, the ozone concentration of generation is too high, people can be known from experience and caused serious injury, it should strict control clarifier air-out The ozone concentration of mouth, makes whether the generation rate of ozone meets national standard.

Photocatalyst itself does not change under the irradiation of light, can but promote the nuisance in the material air of chemical reaction Matter such as formaldehyde, benzene are degraded under light-catalysed effect, generate nontoxic material, and the bacterium in air is also purple Outer light is removed, and therefore air is purified.Have the disadvantage that photocatalyst must be acted in competence exertion under ultraviolet irradiation.Photocatalyst Necessary air velocity is relatively low, and purification speed is slow, easily loses effectiveness by dust covering, it is necessary to often clean or apply again Dress.

Existing air purifier based on filtering, PARA FORMALDEHYDE PRILLS(91,95), VOC（VOC, volatile organic compounds）It is limited etc. removal effect, it is unsuitable for interior and uses.
