Haze dispersing and surface air cooling system

Abstract

The invention discloses a high-altitude air pumping system. The high-altitude air pumping system is mainly formed by an air balloon, a high-altitude air pumping machine, an air feeding pipeline, a ground pressurizing fan, a high-strength cable, a pulley base, a winch, a power supply and a controller. In places around a city which is in haze and an urban district, by reasonably allocating the high-altitude pumping systems in a certain number, a large amount of relatively clear high-altitude air can be pumped from a certain altitude to the ground, and thus the concentration of pollutants in surrounding ground air can be diluted; meanwhile, because of the increment of the total capacity of local ground air and the difference between the pressure and the temperature of mixed air and those of the surrounding air, the transverse moving or ascending of local air can be inevitably caused; under an ideal situation, the affect of a thermal inversion layer can be locally weakened, and thus the haze over the city can be dispersed; in the midsummer, for a city suffering from a heat island effect, a large amount of high-altitude air with lower temperature can be pumped to the ground, thus the local ground air temperature can be reduced, and the city air quality can be improved.

Description

technical field [0001] The invention relates to the control of urban smog and the mitigation of urban heat island effect. Background technique [0002] Air pollution and temperature inversion may lead to smog. In urban areas, due to the lack of wind and the lack of up-and-down air convection, a large number of smog from motor vehicles and floating objects produced by other pollution sources are not easy to spread, and the concentration of fine particulate matter (PM2.5) in the surface air may rise sharply. serious harm to the health of the human body. [0003] In order to reduce the hazards of smog weather, on the one hand, local governments discourage people from reducing outdoor activities; on the other hand, they can promote the use of zero-emission vehicles through administrative means, restricting the driving of fuel-fueled vehicles and emissions from industrial pollution sources. Nevertheless, there is still a lack of effective means to disperse smog in the world at ...

AI Technical Summary

Problems solved by technology

The heat island effect not only affects people's health, but also further increases power consumption and pollutant emissions due to the widespread use of air conditioners.
