Description
Technical field
The utility model relates to measuring instrument field, particularly relates to suspended particle specific charge measuring instrument.
Background technology
Haze is the interactional result of specific weather condition and mankind's activity.The economy of high density population and social activities will inevitably discharge a large amount of fine particle (PM2.5), once discharge exceedes atmospheric air circulation ability and carrying degree, by continued accumulation, if now affected by quiet steady weather etc., very easily there is large-scale haze in fine particle concentration.
Fog seems gentle, the inside but reaches kind more than 20 containing various harmful fine grained, noxious material, include acid, alkali, salt, amine, phenol etc., and dust, pollen, acarid, influenza virus, tubercle bacillus, pneumococcus etc., its content is tens times of normal atmospheric water droplet.Compared with mist, the healthy harm of haze to people is larger.Because the floating particle thing diameter of granular tiny in haze is generally below 0.01 micron, directly bronchus can be entered by respiratory system, even lung.So the respiratory system of what haze had the greatest impact is exactly people, the disease caused mainly concentrates on that breathing problem, cranial vascular disease, nasal cavity inflammation etc. are sick plants.Meanwhile, during haze weather, air pressure reduces, Inhalable Particulate increases suddenly, air flow property is poor, and what harmful bacteria and virus spread towards periphery slows, and cause virus concentration in air to increase, the risk of transmission is very high.Environmental Protection Agency issues " about air particle interdisciplinary science assessment report " for 2009 and points out, have enough scientific research results to demonstrate Fine Particles can adsorb and have carcinogen and genotoxicity mutagen matter in a large number, very important negative effect is brought to health, comprise and improve mortality ratio, make chronic disease aggravate, make respiratory system and cardiac system disease progression, the immune structure etc. of the human body that changes pulmonary function and structure, affects fecundity, changes.
According to Beijing Municipal Health Bureau's statistics, occur the weather of severe haze, the patient that the division of respiratory disease carrying out various big hospital directly under the jurisdiction of a municipal government is gone to a doctor just increases 2-5 and becomes at every turn.More produce the French performer of Beijing participation international film festival, be hospitalized for treatment because of breathing problem by quick-fried with the Reynolds that allows that " this assailant is not too cold " is well-known, special visit is also cancelled temporarily.
More seriously, air pollution can also affect the fertility of the mankind and the health of infant.Expert claims, and is exposed to the animal of rich air pollutant embryo and infant period, and the fertility of the colony that adulthood of comparing is exposed in contaminated environment is decreased significantly.
Cover in the research of five continents at one, researcher has done 100 multinomial researchs, comprehensive more statistics and larger sample, calculate the relation of most of pollutant in the air such as heart disease risk and dust, ozone, nitrogen monoxide, carbon monoxide and sulphuric dioxide.They find, for the most of air pollutants except ozone, even if the exposure being less than 7 day time also can increase the concurrent probability of heart disease.For dust, in air, often increase the concentration of 1 microlitre, by the heart disease probability of increase by 2.5%.This just means, if the concentration of dust granules reaches 10 micrograms/cubic meter in a city, and the concentration of closing on city reaches 20 micrograms/cubic meter, and the probability suffered from a heart complaint in this city increases by 2.5% than first city.
Numerous experts in the United Nations's air environmental protection field study confirmation, ecological negative ion (small particle diameter negative ion) can make an initiative sally and catch granule micronic dust, make it condense and precipitate, effective removing air 2.5 microns (PM2.5) and following micronic dust, the even particulate of 1 micron, thus reduce PM2.5 to the harm of health, the clean-up effect of ecological negative ion to air comes from the bacterium in negative ion and air, dust, the particulate of the positively chargeds such as smog combines, and be polymerized to fall and eliminate PM2.5 harm, coincidentally negative ion does Brownian movement (motion of " it " font) in atmosphere, and the effective ways of minute dusts thing are inherently eliminated in Brownian movement, negative ion eliminates floating dust in conjunction with promoting floating dust Brownian movement after floating dust, experiment proves, floating dust diameter is less, more easily precipitated by negative ion.
And in prior art, not for the instrument measuring haze particle specific charge, by the research to haze specific charge, further can design more suitably ecological charged particle and, to catch granule micronic dust, play the effect alleviating haze by let us.
Therefore, prior art has yet to be improved and developed.
