Description

A kind of high-altitude sampler for the acquisition of black carbon
Technical field
The present invention relates to atmospheric sampling equipment technical field more particularly to a kind of high-altitude samplers for the acquisition of black carbon.
Background technique
The research report of United Nations Environment Programme and World Meteorological Organization's publication is shown, controls black carbon and near-earth ozone etc. The discharge of " smog " helps reply global warming, compared with reducing emission of carbon dioxide, works faster, operates simpler.The mankind will be from now on If adopting an effective measure and controlling black carbon and near-earth ozone discharge for 20 years, it will significantly delay global warming, improve crops every year 50,000,000 tons of yield.
Black carbon is the unburnt byproduct such as fossil fuel.Smog, coal produced by forest fire smoke, brickkiln are fired This kind of black solid little particulate is often retained in cigarette.Black carbon is stronger to sun light absorpting ability, is attached to the whites such as iceberg snow lid Behind surface, heat is on the one hand absorbed, reflection is on the one hand hindered, accelerates iceberg, ice field and arctic melting, then accelerates the whole world Warm speed.In addition, black carbon is one of pollution factor of air quality surveillance, it is believed that exist with diseases such as lung cancer and be associated with.
Black carbon is different from most of Air Pollutants, and the residence time is shorter in atmosphere.The black carbon of regional atmospheric simultaneously The evolutionary process of aerosol concentration is that many factors such as contaminated source, meteorology, a underlying surface are comprehensive on different time and space scales The Dynamic Coupling complex process of influence, these processes betide different time scales, thus the temporal-spatial evolution of black carbon aerosols Show the non-linear of height, variability and non-stationary characteristic.These complexity features cause black carbon aerosols concentration in the time With in spatial distribution have very strong variability, it is difficult to the accurate information of its spatial and temporal distributions and evolution trend is obtained, so that atmosphere Aerosol become in the research of current environmental and climatic change one it is not only important but also be difficult to the uncertain factor accurately estimated, it is serious to hinder Hinder mankind's objective understanding black carbon aerosols to the exact effect of environmental and climatic changes.Due to the strong spatial and temporal variation of black carbon Property, vertical distribution variation also very greatly, lacks the black carbon sampling analysis means of synchronous different height at present, thus lacks not It is level to synchronize black carbon observation data, only assume that it decays with altitude index in research, then by the diffusion of atmosphere, transmission The value for obtaining time, spatial point, causes to miss by a mile in this way.
Still further aspect, at present it has been found that black carbon particle has great specific surface area, can adsorb many toxic has Harmful polluter, such as the harmful chemical substance of sulfur dioxide, polycyclic aromatic hydrocarbon.Traditional black carbon mensuration means mainly lean on light Learn gray scale mensuration, principle is built upon on the particle collected on quartz filter paper band decays caused by the absorption of light.The party Method can be with the concentration of the black carbon of real-time measurement, but this method cannot be used for further analyzing other adsorbed harmful gas of black carbon sample Body ingredient.Therefore establishing more scientific and reasonable black carbon acquisition method and device is very important.
