Description
Technical field
The present invention relates to a kind of new wind filtration system and application thereof, particularly relate to a kind of cleaning system and the application thereof that can improve IAQ.
Background technology
Along with the development of economy, and global industry degree is more and more come high, causes serious pollution to air.Especially in recent years haze weather occurs frequent, and PM2.5 pollution index becomes the important indicator 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, EU criteria is 22 μ g/m
3, and the World Health Organization (WHO) is year average 10 μ g/m in " air quality criteria " criterion value that 2005 formulate
3, annual average is 25 μ g/m
3.Contrast above standard, the current life of urban resident of Chinese 1% is at 40 below μ g, the resident living of 58% is at 100 more than μ g, current research show, haze can make fresh lung 6 days blackening lungs, PM2.5 particle to the damage of lung once formed, treatment cost and time will increase greatly, if formed " black lung ", the difficulty thoroughly eliminated increases greatly, almost may without reverse.
Due to outdoor air severe contamination, cannot to window ventilation, and room air how, the fact is, room air than outdoor air also to pollute serious, just pollutant structure is different, is mainly derived from several aspect: the 1) dust of finishing generation, personnel, dyestuff, aerosol spraying, outdoor enters, reentrainment of dust.These pollutants easily cause pneumonia, pulmonary emphysema, lung cancer, pneumoconiosis, silicosis etc., and toxic granulations can penetrate alveolar tissue and enter blood, flow into liver, kidney, brain, bone.2) biological pollution: the microorganism that personnel carry, disperses after air conditioner water and similar water drying.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 in binding, use the wood-based plate, furniture, coating, paint, cigarette etc. of adhesive.These pollutants easily cause allotriosmia, respiratory tract, inflammation, allergy, abnormal pulmonary function, dysfunction of liver, immunologic dysfunction etc.
Normal adult human will breathe 15 ~ 20m in one day
3air, when people breathe, containing more than 1800 kinds of bacteriums, the injury that room air pollution causes exceedes outdoor 5 times, poisonous suspended particulate in air, and indoor exceed outdoor 60 times.According to the World Health Organization 2006 annual report, annual 2000000 minors die from air pollution, and bioscience man finds, with modern medical service level, if reduce air pollution, people can live 30 years more.And the disease of 68% is relevant with room air, the cancer of 80 ~ 90% is relevant with living environment, and BJ Children's Hospital further investigation reveals that, has the family of 90% to carry out finishing in leukemia children within half a year, China's 90% new decorating house formaldehyde.
Solution at present for indoor air circulation purification mainly contains: 1) indoor air-purifier, indoor air-purifier principle is the requirement by meeting people to the purification of the intrinsic air in indoor, but there are two large defects in indoor air-purifier, to such an extent as to makes this solution lose meaning completely: first, do not have fresh air to enter under air-proof condition, cause anoxic, gas concentration lwevel is too high, if when air-proof condition is bad, limit purifies, limit is polluted, and does not thoroughly solve purification of air; Secondly, because clarifier is side air draught, air-out after filtering, both sides air forms negative pressuren zone and zone of positive pressure, and the air filtered can flow to negative pressuren zone from zone of positive pressure by the shortest path, such iterative cycles, makes air at a distance can not get purification.2) the new blower fan of self-balancing, side air intake, leads to new blower fan by pipeline, then by pipeline to indoor air-supply, meanwhile, an other road, air draught indoor, by new blower fan, and then by pipeline to outdoor air draft, can realize cold and hot exchange, economize energy.But need a large amount of pipe laying, cannot implement after finishing; The pipeline time, strong point was in blast state, there will be air leakage phenomena, and was difficult to discover, not easily detect and keep in repair, therefore can cause secondary pollution after using a period of time; Filtration only has primarily efficient filter, does not therefore have effect to PM10, PM2.5.3) by the new blower fan of air intake that HEAP filters, effectively PM2.5 can be filtered, easy for installation.But there is serious relaxation phenomenon in HEPA screen pack, As time goes on, the effect of filtration reduces gradually, more detrimentally, user does not know when decay to what degree, time wait will change HEAP, Severe blockage, and when in outdoor air, PM2.5 concentration is very low, also PM2.5 pollutant can be discharged out on the contrary in filter screen, 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 the need to consumptive material, without the need to changing.But poor filtration effect, filters unstable.
To sum up, there is no indoor air cleaning system effectively at present, especially for the air cleaning system of PM2.5 pollutant.
