A method of reducing smog based on breaking through the temperature inversion layer

Abstract

The invention relates to the field of atmosphere pollution treatment, in particular to a haze reducing method based on a breakthrough thermal inversion layer.In an open environment, cold air, with haze, of a near-earth region is heated and compressed and subjected to vertically-upward forced lasting jetting so that a high-temperature air column can be formed, the high-temperature air column is formed, and an upper-cold and lower-hot temperature gradient convection air column is maintained; when the convection air column breaks through the top of the thermal inversion layer, a channel favorable for vertical convection of the atmosphere is formed, and haze in a channel area is dispersed into the overhead portion of the top of the thermal inversion layer along with ascending airflow; along with decreasing of the concentration of haze in the channel, haze in the surrounding area is dispersed into the channel, air in the surrounding area carries the haze to be gathered in the channel, circulation that haze is dispersed to high altitude is formed, and reduction of haze in a certain area is achieved.

Description

technical field [0001] The invention relates to the field of air pollution treatment, in particular to the formation of atmospheric convection in a vertical direction in a certain area by spraying high-temperature compressed air and infrared radiation, and by changing the local temperature gradient of the temperature inversion layer, assisting the upper boundary of the generated atmospheric convection to advance to high altitude , and finally generate a vertical convection channel of gas that runs through the inversion layer vertically, so as to achieve the effect of making the haze break through the inversion layer to diffuse and reduce air pollution near the ground. Background technique [0002] Haze is a combination of fog and haze. Since both have the effect of reducing visibility and can be transformed into each other under certain conditions, the boundaries of the definition are not clear, so they are generally referred to as haze. Fog is the condensation or sublimatio...

Problems solved by technology

At the same time, the fine particles in the smog have a strong scattering and absorption effect on sunlight, greatly reducing the sunlight radiation received by the ground, which will further enhance the strength of the inversion layer, causing a vicious circle

[0004] At present, the methods of treating smog through electrostatic adsorption and dust bag filtration focus on reducing the emission of suspended particulates, which have been proved to be effective in the flue environment, but the treatment effect on the smog that has been dispersed in the open environment is not ideal

The method of building high-altitude exhaust pipes to climb over the temperature inversion layer has a long project period, and the high-altitude pipes are not easy to maintain

The large-scale microwave bombardment inversion layer method has large equipment volume and high cost
