Problems solved by technology

[0004] Although artificial rainfall can reduce PM2.5 by means of wet deposition, when the wind speed is low and the humidity is high, the impact of rainfall on PM2.5 concentration is not significant
Moreover, the cold cloud catalysts (such as silver iodide, etc.) used in traditional artificial rainfall to reduce smog only have a condensation effect on water vapor, and have no obvious adsorption effect on fine particles such as PM2.5
This makes relying on the traditional method of artificial rainfall not ideal for dissipating smog, nor will it fundamentally resolve the problem of smog

Abstract

The invention discloses a cold cloud catalyst for spraying aerocolloid at high altitude and reducing fog and haze, and a preparation method thereof. The cold cloud catalyst is prepared from the following components in parts by weight: purified lake water, silver iodide, sulfosuccinate, disodium mono(polyoxyethylene alkyl)sulfosuccinate, 3-amino-N,N-diethyl-4-methoxybenzenesulfonamide, 1-amino-4-hydroxyl-9,10-amerantrone, 1-amino-4-anilino-2-bromoanthraquinone, sodium dodecyl sulfate, copper nanoparticles, 4-bromo-1-amino anthraquinone-2-sulfonic acid, polyoxyethylene polyoxypropylene ether, 1-amino-2-anthraquinonecarboxylic acid, N-alkylbenzotriazole, 2-(6-methyl-2-benzothiazolylazo)-5-diethylamino-phenol and dialkyl sulfosuccinate. The cold cloud catalyst has the advantages that particulate pollutants are removed from the air by a new technology of performing low-tension and efficient purification on the air polluted by fog and haze, so that the particles are dispersed and absorbed; and the catalyst can reduce the surface tension, is simple in structure and convenient to operate, and can realize automatic control.

Description

technical field [0001] The invention belongs to the field of atmospheric control, and in particular relates to a high-altitude spraying aerogel cold cloud catalyst for reducing smog and haze and a preparation method thereof. Background technique [0002] Smog seriously endangers human health, road traffic safety and the ecological environment. However, there are no effective measures and solutions for the control of smog at present. Vehicle restrictions, water spraying, installation of air purifiers, and large-scale holiday factory shutdowns can partially alleviate air pollution, but they are not enough to fundamentally solve the smog problem. Instead, they cause a lot of waste of water resources and increase electricity load . In recent years, the state has increased investment in smog control from the government level, and the artificial rainfall method is regarded as one of the most effective technologies that is expected to solve the smog problem. [0003] At present,...
