Description
Technical field
The utility model relates to Study of Atmospheric Environment technical field, especially relates to a kind of haze analogue means.
Background technology
Haze is common in city, and mist is incorporated to haze and carries out early-warning and predicting as diastrous weather phenomenon together by the many areas of China, is referred to as " haze weather ".
Haze is the portmanteau word of mist and haze.Mist is a kind of nontoxic natural phenomena in fact, the condensation vapor suspended in air, and low visibility is in 1000 meters time, and meteorology is just called mist.When the steam of Air containment reaches to greatest extent, just occur saturated.If steam is more than saturation capacity, unnecessary will condense out, and dust granule small in air is combined, and forms little water droplet or ice crystal, is suspended in subaerial air layer, becomes mist.Temperature is lower, and the steam that can hold in air is also fewer, more easily forms haze.Haze is usually accompanied, and haze occurs simultaneously, and the conditions such as steam, quiet wind, inversion, the nuclei of condensation are indispensable.
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, once discharge exceedes atmospheric air circulation ability and carrying degree, fine particle concentration, by continued accumulation, if now affected by quiet steady weather etc., very easily occurs large-scale haze.
In haze weather, PM2.5 is chief-criminal, and main source has multiple: one is vehicle exhaust, and in recent years, the automobile in city gets more and more, and the car tail tolerance of discharge also gets more and more, and accounts for about 60% to " contribution " of PM2.5 in city; Two is dust on the roads and construction airborne dust, accounts for about 20% of PM2.5 source; Three is secondary pollutions that factory produces; The pollutant of four low-altitude dischargeds of burning coal when being warmings; Five is the burning of living beings and the flue dust of waste incineration generation.
Containing harmful in a large number fine grained, noxious material in haze, long-term suction can have a strong impact on health, is embodied in:
(1) respiratory health is affected:
The constituent of haze is very complicated, comprises hundreds of Atmospheric Chemistry particulate matter.Wherein, the particulate that the mainly diameter be harmful to health is less than 10 microns, as mineral grain thing, sea salt, sulfate, nitrate, Organic aerosol particle, fuel and automobile exhaust gas etc., it directly can enter and stick in human respiratory tract and alveolar.Especially submicron particle can be deposited in upper and lower respiratory tract and alveolar respectively, causes the illness such as acute rhinitis and acute bronchitis.For chronic respiratory disease patients such as bronchial astehma, chronic bronchitis, obstructive emphysema and COPDs, haze weather can make state of an illness acute attack or acute exacerbation.If be in this environment for a long time also can bring out lung cancer.
(2) cardiovascular system is affected healthy:
Haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, normal blood circulation can be hindered, cause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, angina pectoris, miocardial infarction, heart failure etc. may be brought out, make chronic bronchitis occur cor pulmonale etc.
In addition, thick fog weather pressure ratio is lower, and people can produce a kind of sensation of agitation, and blood pressure can increase naturally to some extent.On the one hand often temperature is lower the greasy weather again, and some hypertension, patients with coronary heart disease go to suddenly cold outdoor from warm indoor, blood vessel expands with heat and contract with cold, and blood pressure also can be made to raise, cause the generation of apoplexy, myocardial infarction.
(3) haze weather also can cause that surface layer is ultraviolet to be weakened, and make the increased activity of the infectiousness germ in air, infectious disease increases.
(4) child growth is unfavorable for:
Because sunshine in greasy weather reduces, children's Ultraviolet radiation is not enough, and in body, vitamin D generates not enough, greatly reduces, serious meeting causes Infant Rickets, children growth slows down to the absorption of calcium.
(5) mental health is affected:
Expert points out, there is impact in the lasting large greasy weather on the psychology of people and health, and say psychologically, the large greasy weather can cause oppressiveness, oppressive impression to people, can stimulate or aggravate the state of mental depression.In addition, due to the low pressure that greasy weather light is more weak and cause, some people can produce spiritual sluggishness, listless phenomenon in the greasy weather.
On November 5th, 2013, " climate change Green Book: reply climate change report (2013) " (hereinafter referred to as " Green Book ") that the Chinese Academy of Social Sciences, China Meteorological Administration combine issue is pointed out, immediate and mid-term China haze weather is totally in increase trend.Wherein, mist number of days is in obviously reducing, and haze number of days obviously increases, and continuation haze process increases significantly.
Haze weather phenomenon causes significant negative effect can to weather, environment, health, economic dispatch aspect, such as, cause urban atmosphere acid rain, photochemical fog phenomenon, cause atmospheric visibility to decline, and hinders aerial, the water surface and the traffic of face, land; Improve the death rate, make chronic disease aggravate, make respiratory system and cardiac system disease progression, the immune structure etc. of the human body that changes PFT and structure, affects fecundity, changes.
2013, " haze " became annual keyword.In the January of this year, 4 times haze process shrouds 30 provinces (district, city), and in Beijing, only having 5 days is not haze sky.Have report display, in 500 cities of Largest In China, only reach the air quality standard of world health organisation recommendations less than the city of 1%, meanwhile, polluting 10 the most serious cities in the world has 7 in China.
2014, national mitigation was done, the haze weather of health risk is included in natural the condition of a disaster in 2013 and circulated a notice of by Ministry of Civil Affairs first.
Current technology, only recognizes the formation basic theory of haze, but the actual conditions formed the forming process of haze, haze, haze are understood very few with the variation tendency etc. of weather condition, and a lot of research work is difficult to launch.
Existing mist analogue means is use humidifier or other atomising devices mostly, directly to carrying steam particle in test space, greatly differing from each other with natural mist formation condition, being difficult to use in and studying the Formation and Evolution of haze.
