Description

New wind filtration system
Technical field
The utility model relates to a kind of new wind filtration system, relates in particular to a kind of cleaning system that can improve IAQ.
Background technology
Along with economic development, and global industrialization degree more and more comes highly, to atmosphere, caused serious pollution.Especially in recent years haze weather occurs that frequently, PM2.5 pollution index becomes the important indicator of evaluating air quality.As far back as 2006, EPA was that PM2.5 is no more than 33 μ g/m with regard to air quality ideal standard 3, European Union's standard is 22 μ g/m 3, and the < < air quality criteria > > criterion value that the World Health Organization (WHO) formulated in 2005 is year average 10 μ g/m 3, annual average is 25 μ g/m 3.Contrast above standard, the life of urban resident of China 1% is below 40 μ g at present, 58% resident living is more than 100 μ g, current research demonstration, haze can make 6 days blackening lungs of fresh lung, once PM2.5 particle forms the damage of lung, treatment cost and time will increase greatly, if formed in " black lung ", the difficulty of thoroughly eliminating increases greatly, almost may without reversing.
Due to outdoor air severe contamination, the ventilation of cannot windowing, and room air is how, the fact is, it is serious that room air also will pollute than outdoor air, just pollutant structure is different, is mainly derived from several aspects: the dust that 1) finishing produces, personnel, dyestuff, aerosol spraying, outdoor entering, reentrainment of dust.These pollutants easily cause pneumonia, pulmonary emphysema, lung cancer, pneumoconiosis, silicosis etc., and the penetrable alveolar tissue of toxic granulations enters blood, flow into liver, kidney, brain, bone.2) biological pollution: the microorganism that personnel carry, after air conditioner water and similar water are dry, disperse.These pollutants easily cause pneumonia, rhinitis, respiratory tract anaphylaxis, allergic.3) formaldehyde, phenyl ring class toxic gas.Derive from air aldehyde resin etc. for the raw material of binding, use the wood-based plate, furniture, coating, paint, cigarette of adhesive etc.These pollutants easily cause allotriosmia, respiratory tract, inflammation, allergy, abnormal pulmonary function, dysfunction of liver, immunologic dysfunction etc.
Normal adult human will be breathed 15~20m in one day 3air, when people breathe, contains and surpasses 1800 kinds of bacteriums, and the injury that room air pollution causes surpasses outdoor 5 times, and poisonous suspended particulate in air is indoor over outdoor 60 times.According to the World Health Organization's 2006 annual reports, annual 2000000 minors die from air pollution, the discovery of bioscience man, and with modern medical service level, if reduce air pollution, people can live 30 years more.And 68% disease is relevant with room air, 80~90% cancer is relevant with living environment, and BJ Children's Hospital further investigation reveals that, has 90% family within half a year, to carry out finishing, China's 90% new decorating house formaldehyde in leukemia children.
The solution purifying for indoor air circulation at present mainly contains: 1) indoor air-purifier, indoor air-purifier principle is by the purification of indoor intrinsic air being met to people's requirement, but there are two large defects in indoor air-purifier, to such an extent as to makes this solution lose meaning completely: first, under air-proof condition, do not have fresh air to enter, cause anoxic, gas concentration lwevel is too high, if in the bad situation of air-proof condition, limit purifies, pollute on limit, does not thoroughly solve air cleaning; Secondly, because clarifier is a side draught wind, air-out after filtering, both sides air forms negative pressuren zone and zone of positive pressure, and the air having filtered can pass through the shortest path flow to negative pressuren zone from zone of positive pressure, and iterative cycles, makes air at a distance can not get purifying like this.2) the new blower fan of self-balancing, a side air intake, by device for cleaning pipeline to new blower fan, then by pipeline to indoor air-supply, meanwhile, an other road, from indoor air draught, by new blower fan, and then by pipeline to outdoor air draft, can realize cold and hot exchange, save the energy.But need a large amount of pipes laying, after finishing, cannot implement; Pipeline time strong point, in blast state, there will be air leakage phenomena after use a period of time, and is difficult to discover, and is difficult for detecting and maintenance, therefore can cause secondary pollution; Filtration only has primarily efficient filter, and therefore to PM10, PM2.5 does not have effect.3) the new blower fan of air intake filtering by HEAP, can effectively filter PM2.5, easy for installation.But there is serious relaxation phenomenon in HEPA screen pack, As time goes on, the effect of filtration reduces gradually, and more harmful is, user does not know when decay to what degree, when wait will be changed HEAP, seriously stopped up, and when in outdoor air, PM2.5 concentration is very low, in filter screen, also can discharge PM2.5 pollutant out on the contrary, HEPA screen pack can not clean, and can only change, and use cost is very high.4) by the new blower fan of electro static filtering, advantage is without consumptive material, without replacing.But poor filtration effect, filters unstable.
To sum up, there is no at present indoor air cleaning system effectively, especially for the air cleaning system of PM2.5 pollutant.
