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

Embodiment Construction

[0020] A cold cloud catalyst for alleviating smog. The cold cloud catalyst for alleviating smog is AgI. AgI is used to induce the AgI crystal film with a pulse energy of 30mJ to change its structure, thereby promoting the formation of whiskers. growth, obtain the modified silver iodide of whiskers with electrostatic effect of the present invention, as an excellent cold cloud catalyst for alleviating smog.

[0021] The AgI preparation method in the present embodiment is as follows:

[0022] A. Slowly drop 0.2mol / L silver nitrate aqueous solution into 0.2mol / L KI solution and stir evenly with a magnetic stirrer at room temperature. The volume ratio of silver nitrate aqueous solution and KI solution is 1:1;

[0023] B. Stand still for 2 hours to obtain silver iodide precipitated powder, then repeatedly filter and wash with deionized water, so as to eliminate the residue of chemical reaction;

[0024] C. Put the precipitated silver iodide powder into a vacuum drying oven and dry ...

Abstract

The invention discloses a cold cloud catalyst for relieving haze. AgI is taken as the cold cloud catalyst for relieving haze; an AgI crystal surface is provided with a crystal whisker having electrostatic effect; AgI adopts laser with pulse energy of 5-50mJ for inducing an AgI crystal film, so that the structure is changed and the increasing of the crystal whisker is further boosted; the cold cloud catalyst for relieving haze with the crystal whisker having electrostatic effect provided by the invention is finally acquired. The cold cloud catalyst for relieving haze provided by the invention has an excellent adsorption effect on PM2.5 and other fine particulate matter.

Description

technical field [0001] The invention relates to a cold cloud catalyst for reducing smog. 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. The China Meteorological Administration has issued the "Implementation of the Action Plan for Air Pollution Prevention and Control". One of the effective techniques. [0003] At present, the catalysts used in artificial rain enhancement are usually divided into three categories: the firs...
