Description
Technical field
The utility model belongs to air contaminant treatment technical field, particularly relates to a kind of air purifier of administering haze on a large scale.
Background technology
Haze is the mixture of mist and haze, and sooner or later during high humidity, the composition of mist is many.Daytime, haze occupied the main force during high humidity, and relative humidity is between 80% to 90%.Wherein mist is natural weather phenomenon, the water in air vapour generative forces of heaven and earth.Although using dust as the nuclei of condensation, totally nontoxic; The core substance of haze is to be suspended in the materials such as airborne cigarette, dust, wherein contains various germ materials, and health is produced to injury greatly, and relative air humidity is lower than 80%, and color is turned to be yellow.Gas can directly enter and stick in human body lower respiratory tract and the lobe of the lung, and health is had to injury.The formation of haze weather is to be mainly artificial environmental pollution, adds the natural conditions such as temperature is low, wind is little and causes pollutant to be difficult for diffusion.On January 4th, 2014, country includes haze weather in first natural the condition of a disaster in 2013 and circulates a notice of.February 20 started, and 1/5th territories, the whole nation meet with haze, and therefore administering haze is the problem that we must face.
At present, Pm2.5, Pm10 that majority state haze contamination phenomenon both domestic and external causes are more and more serious, along with change
The increase of stone fuel consumption, pernicious gas concentration in air such as the sulfur dioxide producing after its burning and nitrogen dioxide constantly increase, these pernicious gases carry out physical and chemical reaction by sunlight and the mutual catalysis of airborne moisture content, and the aerosol of generation nitrogen oxide particulate, the chemical fumes particulate that wherein 0.1 μ m to 10 μ m is showy is maximum to the harm of human body, and its source is that fossil fuel high-temp combustion is discharged into fumes of sulphuric acid in atmosphere and the dust of photochemical fog and industrial processes.
For this reason, countries in the world are all at development Domestic indoor air purifying device, but this can only solve the governing problem of Pm2.5 in family room, yet outdoor below standard Pm2.5 still invades indoor, can not be fast and initiatively eliminate pernicious gases such as above-mentioned nitrogen oxide in atmosphere and the aerosol particles pollutant of PM2.5, thus serious haze pollution situation at present can not be changed.
Someone also proposes to use the way of rain making, haze is administered, yet, Central Meteorological Observatory's chief predictor
Hippology money expert points out " by rain making, eliminating haze, both uneconomical also unrealistic ", and this is because rain making must have certain condition,, must have certain cumulonimbus layer that is, and is just in the overhead in haze area.If it is also impracticable adopting the mode of water spray, because there is no the water of these super flood tides can use, also spray on the top that can not cheaply the water of these super flood tides be taken to haze layer, make water eliminate haze, control bad meeting and make water become droplet, increase the weight of on the contrary haze, only on ground, to spray a large amount of water now, substantially be not have effectively, the too many road surface of Spraying Water in Winter also easily freezes, so use spraying to eliminate haze, is actually impracticable.
In addition, really the method that also has nothing better at home and abroad at present, can administer fast, cheaply haze, the situation of haze is more and more serious situation, this point is the common recognition of national all circles, must try every possible means it to administer fast, cheaply, otherwise Arrested Development not only, and under the shrouding of serious haze, it is nonsensical that the economic well-being of workers and staff of all becomes.
