Method and device.
Background technology
Increasingly sharpening for air pollution is pendulum vital task urgently to be resolved hurrily in face of people.The source of pollution includes outstanding
Floating particle, such as gasoline, diesel oil fuel combustion, the incineration of garbage, building, metal smelt etc.；Sulfur dioxide (SO2), such as with coal
And oil makees the smelting furnace of fuel, metal smelt etc.；Carbon monoxide (CO), is mainly discharged by automobile；Carbon dioxide, such as lives and fires
The carbon dioxide of material burning release；Each hydrocarbon, is produced by the operations of various industry, such as dry-cleaning, industrial coating evaporation,
Industrial product cleaning etc.；CFCs, is such as used for cold gas system and refrigerator as coolant, sends out to manufacture as foaming agent
Bubble glue, as the injecting substances of spray, as solvent cleaned circuit board and computer fittings etc..Air pollution can appreciable impact people
The health of class and other biological, various diseases are relevant with environmental pollution, such as respiratory system disease, disease in the blood system, cancer, the heart
Vascular system disease etc..Sulfur dioxide and nitrogen compound can produce acid rain, the ore deposit in the growth of impact plant and soil in air
Material.CFCs can damage the ozone layer in air.The concentration of carbon dioxide increases year by year in air, so that may cause
" greenhouse effect ", the temperature rises to make the earth.Airblrne particulates increase can affect visibility.Pollutant in local air
Accumulation depends on three conditions：Pollutant emission, the quiet wind in ground and atmospheric inversion layer are formed.The pollutant in city produce speed and show
Write more than rural area.City it is also so-called " pot cover effect, thus the mass rate of emission of its pollutant be significantly lower than surrounding, make city
The pollution level in city is significantly greater than rural area.In some with serious pollution big cities, people are often being rained or just can seen after blowing
Blue sky.Therefore urban air pollution is reduced, in addition to the generation and discharge of strict control pollutant, is tried to manufacture or is accelerated
Air flow, increases the removing speed of pollutants in air, can produce significant pollution improvement of environment effect.
At present maximum air pollution is haze, the increase and SEQUENCING VERTICAL direction mainly due to pollutants in air discharge

The Fence structure of high 3 meters of rice.Liquid nitrogen is sprayed in Fence structure, air cooling-down in Fence structure is made, about 10 degree inside and outside formation
The temperature difference, keeps liquid nitrogen sprinkling.Experimental example (six) air pollutants are heated into the central authorities that clearance technique device is put into Fence structure.
Outside Fence structure, wheat straw burning is blown into combustion fumes in Fence structure from the bottom of Fence structure, observes and record smog
1 hour of dissipation situation.Then experimental example (six) the air pollutants heating clearance technique device for being positioned over central authorities is lighted, is seen
Examine and record the dissipation situation of smog.
3) experimental result：When smog sprays into Fence structure Inner, observe 1 hour, the smog in Fence structure is without obvious
Dissipation sign.After lighting positioned at experimental example (six) the air pollutants heating clearance technique device in Fence structure central authorities, it is seen that
Smog above firing device spreads rapidly, and then also quickly diffusion disappears the smog of surrounding.Repetition test, from experimental example (six)
Air pollutants heating clearance technique device light after to smog fully erased time be 4.8-6.3 point.Illustrate that inversion layer is
The key factor for maintaining contaminants stable, the technology of the present invention device can accelerate air-polluting removing.
It should be noted that not discharging the impact of extraneous factor in the embodiment of above-mentioned simulation experiment.Although simulation
Do not increase external interference factor, such as wind, rain, snow natural cause in experiment, but in the case where there is haze, wind, rain, snow
It is benign etc. removal of the natural cause to haze, can accelerates to remove haze, and in normal fine day, the effect energy of the present invention
Haze is enough removed, can only preferably remove haze, without to haze if there is with other natural causes and situation about depositing
Increase play any facilitation.
Apply specific case in the present invention to be set forth the principle and embodiment of the present invention, above example
Illustrate that being only intended to help understands the method for the present invention and its core concept；Simultaneously for one of ordinary skill in the art, according to
According to the thought of the present invention, will change in specific embodiments and applications.In sum, this specification content
Should not be construed as limiting the invention.
