Description
Technical field
The present invention relates to a kind of outdoor environment temperature reduction purification method and device, be meant a kind of method and apparatus that is applicable to that the hot dry densely distributed outdoor environment temperature reduction of airborne dusts such as urban road purifies especially.
Background technology
The a research report of The World Health Organization (WHO) estimates that having every year nearly, 656,000 Chinese die from air pollution.Air pollution estimates to cause every year about 2,000,000 people in the whole world dead too early.And in air pollution, the city dust on the roads of mating formation has become one of important source of urban environment air particle, and dust on the roads pollutes attention and the concern that ambient air quality and health effects is subjected to day by day the environmental management department researcher.Dust on the roads is meant laying dust on road, the street under the effect of certain dynamic condition (wind-force, motor vehicle roll or the crowd activity), and one or many is kicked up and mixed, and enters into the particle that surrounding air forms certain grain size distribution.The main component of dust on the roads---suspended particles can enter lung by air.The dust of the 0.1mm particle diameter above 50% can be deposited on lung.Suck siliceous dust and more can cause permanent injury human body.Cigarette dirt is common suspended particulates, because particle diameter is little, between 0.001-0.1mm, so extension is strong, almost can not sink in still air, the not only instant visible disastrous effect of polluting, and long-term suction more can cause lung cancer.More people can suffer from the disease of respiratory system, as cough, asthma, bronchitis, expiratory dyspnea etc.According to the study, the concentration of airblrne particulates whenever doubles, and the death rate promptly increases by 15%.
It is main that traditional dust collection method adopts hand sweeping, sometimes because the improper floating dust amount that can increase on the contrary in the environment of cleaning.Except hand sweeping, usually adopt the way of cleaning ground at hot dry weather, in the hope of reaching the double effects of dedusting and cooling, but because the particle water of water sprinkler ejection is bigger, the contact area of particle water and air is limited, the ability of absorption airborne dust particle is relatively poor, can't effectively reduce the concentration of airborne dust particle in the air.In addition, particle water absorbs heat insufficient in air, and cooling-down effect is poor, is finally absorbed by ground after dropping to ground, and humidity is constantly increased, and on the contrary than sultryyer before the watering, and because ground is drenched, can cause pedestrian's the ponding with ground of slipping.Adopt simple watering method water consumption big, the energy consumption cost height.Therefore, can't be applied to the cooling and the dedusting of large space.
The electrostatic spray technology is the nearly in the world 40 years a kind of novel atomization techniques that grow up, the formed trickle droplet of electrostatic atomization, the dust that in transport process, suspends in the absorbed air, the particle diameter spectrum of droplet is narrower, the droplet of band like charges is mutually exclusive, be difficult for coalescence in the space, charged drop near dust granule makes dust granule produce electrostatic induction, under the effect of electrostatic force, be adsorbed on the dust granule surface, increase the deposition that the liquid deposition amount especially can increase substantially dust granule, improved the deposition efficiency of the liquid particle that disperses; Spray in the space, and liquid distribution is even, has reduced the sprinkling dead angle.
Electrostatic spray is compared with traditional mechanical spraying and is had the following advantages:
1, charged thin water smoke drop size is littler than the drop of traditional mechanical atomizer, even size distribution.
2, charged thin water smoke drop is difficult for coalescence takes place owing to having like charges, and disperse is even.
3, charged thin water smoke drop is because electrostatic induction effect dust removing effects is better than traditional mechanical spraying.
The new invention that purifies about environmental dust removal was brought into use spray technique in recent years.Patent CN87213270U patent " aerosolater " discloses a kind of aerosolater, utilizes vaporific molecule and dust in expansion chamber, useless cigarette, and the waste gas contact, when making its generation chemical reaction formation sour water reach excess load, blowoff valve is discharged automatically.This device is suitable for the industrial production of factory and enterprise, directly is contained in and produces dust removing effects on the production equipment, is not a kind of method and apparatus that is applicable to that outdoor environment purifies.Therefore, still lack a kind of efficient new invention of environment protecting and power-saving that is applicable to that outdoor environment purifies at present.
Summary of the invention
One of purpose of the present invention provides a kind of convenience, environmental protection, energy-conservation outdoor environment temperature reduction purification method, a kind of efficiency of dust collection height has been proposed, good cooling effect, energy consumption is low, is applicable to the method and apparatus that the hot dry densely distributed outdoor environment temperature reduction of airborne dusts such as urban road purifies.
