Description

Air cleaning unit

Technical field

The utility model relates to a kind of air cleaner, but particularly a kind of dedusting, removes the air cleaning unit of pernicious gas.

Background technology

In economic, civilized all today of high speed development, the people of the world still is faced with many crises that is threatening the survival and development, and air quality problems is exactly one of them.(Indoor air quality, contamination class IAQ) mainly comprise physical contamination (particle and pollen etc.), biological pollution (bacterium and virus etc.), chemical contamination (inorganic compound and organic compound) and radioactive pollution (radon etc.) to influence indoor air quality.These pollutants are mainly derived from pollution, domestic electric appliance pollution, the pollution of people's own activity and the pollution of outdoor air of construction material and house decorative material.In addition, the class room air pollution source that must carry is exactly a cigarette smoke.According to research, in the smog that cigarette and burning back thereof produce 4000 multiple harmful substances are arranged.The nineteen ninety U.S. " clean air act " amendment has been enumerated 189 kinds of toxic and harmfuls, wherein major part be volatile organic matter in the air (Volatile Organic Compounds, VOCs).VOC is the general name of the class low boiling carbon containing organic compound that can volatilize under normal room temperature, and its typical boiling spread is 50～100 ℃.U.S. EPA is defined as VOCs: except CO ₂, the carbon compound in some and the atmosphere such as carbonic acid, metal carbides, carbonate and ammonium carbonate outside the photochemical reaction.VOCs is made up of material widely, comprising: alkanes, alkene class, aromatic hydrocarbons, chlorinated hydrocabon, ester class, alcohols, aldehydes and ketone etc.Some not the organic substance in outdoor environment VOCs definition in indoor pollution research also by as a kind of VOCs, for example formaldehyde.

Chemical method comprises neutralisation, oxidizing process and catalysis method etc., and wherein, neutralisation is with strong points, and it is single to remove material, consumes the many and life-span weak point of reagent; The consumption of oxidizing process reagent is many, and easily causes secondary pollution; Catalysis method can carry out under normal temperature and low temperature, is only applicable to the concentration condition with higher, and requires not have in the air material that can react with catalyst itself, and price is also expensive.

Ion method comprises anion method and plasma method, but the anion method can't be removed VOCs, and plasma method produces effects very little to the removal of VOCs, and in the process that produces ion, can generate excessive ozone, health there is damaging effect, influences respiratory function, in addition carcinogenic.

Ultraviolet method is to utilize artificial ultraviolet (Ultraviolet, UV) high-energy photons of light is destroyed protein and reached the effect of sterilization, removes VOCs but but can't purify.

How improving air quality, body health benefits has been the thing that urgently can not treat.The air cleaning unit of prior art, its function singleness, even can produce secondary pollution, can not satisfy people's real demand.Not good relatively poor at present indoor environment with the public place air quality, and the still unsafty present situation of the clean-up effect of existing air cleaning unit, need improve existing air cleaning unit, produce a kind of air cleaning unit, can efficiently remove in the air flue dust and wave the voltinism pernicious gas, increase negative aeroion content simultaneously.
