preparation example Construction

[0022] The present invention also provides the preparation method of artificial rainfall agent described in above-mentioned scheme, comprises the following steps:

[0023] Under airtight conditions, sodium chloride and titanium dioxide are stirred and mixed to obtain the artificial rainfall agent.

[0024] In the present invention, the particle size and water content of the sodium chloride and titanium dioxide raw materials should meet the requirements described in the above scheme. If the particle size of the raw material is large or there is agglomeration, the raw material is preferably pulverized. The moisture content does not meet the requirements, it is preferable to dry the raw materials to remove water first.

[0025] The present invention preferably uses a closed stirring device for stirring. During the stirring process, the titanium dioxide particles are automatically coated on the surface of the sodium chloride particles to form a titanium dioxide coating; the presen...

Embodiment 1

[0033] Commercially available edible sodium chloride without iodine and commercially available titanium dioxide are used as raw materials, wherein the particle size of titanium dioxide is 150-200 μm, the particle size of edible sodium chloride is 200-500 μm, and the water content is <1%. Sodium chloride and The mass ratio of titanium dioxide is 80:20. Sodium chloride and titanium dioxide are stirred and mixed in a closed device, so that titanium dioxide is coated on the surface of sodium chloride to obtain an artificial rainfall agent.

Embodiment 2

[0035] Commercially available edible sodium chloride without iodine and commercially available titanium dioxide are used as raw materials, wherein the particle size of titanium dioxide is 250-300 μm, the particle size of edible sodium chloride is 500-900 μm, and the water content is <1%. The mass ratio of titanium dioxide is 90:10. Sodium chloride and titanium dioxide are stirred and mixed in a closed device, so that titanium dioxide is coated on the surface of sodium chloride to obtain an artificial rainfall agent.

Abstract

The invention relates to the technical field of artificial rainfall, and provides an artificial rainfall agent and a preparation method and application thereof. The artificial rainfall agent comprisessodium chloride particles and titanium dioxide coatings coated on the surfaces of the sodium chloride particles. The artificial rainfall agent provided by the invention is non-toxic and harmless, hasstrong water vapor adsorption capacity, can improve the artificial rainfall efficiency and rainfall capacity, and can be used as condensation nucleus to continuously increase water drops and ice crystals in the cloud and reduce the water drops and ice crystals into rain when being scattered in the cloud layer. In the rainfall process, raindrops enable tiny dust particles and the like to fall ontothe ground, so that the effects of removing haze and reducing PM2.5 are achieved. Besides, titanium dioxide has a photocatalysis effect and can degrade pollutants in air and water, so that the haze removal effect is further improved. When the artificial rainfall agent provided by the invention is applied to artificial precipitation enhancement, hail suppression and haze treatment, an excellent effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of artificial rainfall, in particular to an artificial rainfall agent and its preparation method and application. Background technique [0002] Drought conditions are severe as climate change affects more areas than ever before as global warming trends intensify. The average area of ​​cultivated land affected by drought every year in my country is about 300 million mu, and 400 of the 669 cities have insufficient water supply. In particular, 110 of the capital and some large and medium-sized cities are seriously short of water. The overall situation of water resource shortage is becoming increasingly severe and urgent Need to open up new ways to increase water. Atmospheric precipitation is the ultimate source of recharge for surface water and groundwater, and plays a pivotal role in the terrestrial water cycle and the evolution of freshwater resources. my country's annual average total aerial water resources...
