Description

A kind of rain making dust and its application process

Technical field

The present invention relates to rain making field, more particularly to a kind of rain making dust and its application process.

Background technology

So far, rain making and to increase rain artificially be years of researches problem, such as with airplane spray dry ice, iodate Silver, salt fines etc., or got to silver iodide in cloud layer with rocket gun, rain making is realized with this.But, the above method All because its material expensive, expense are too high can not large area, implement rain making for a long time.

The content of the invention

The technical problems to be solved by the invention are to provide the artificial drop that a kind of cheap, the suitable large area of expense is used for a long time Rain dust, while providing the application process of the dust.

Applicant observes several natural phenomenas for many years：First, in typical continental climate area, whenever sleet mistake Afterwards, always there is one layer of dust in outdoor parked vehicle, on building exterior window；Secondly, why Tianshan Mountains, the Qinling Mountains, the mountain of Taihang Mountain Sleet is especially more in the col in underfooting and some mountain areas, because blow west wind China more, blows air over formed at these foots of the hill greatly Underbalance effect, to make these at the foot of the hill or in col rainwater is especially more；Wherein, underbalance effect refers to negative pressure and makes at the foot of the hill to generate A range of air-flow vortex, this air-flow vortex cause dust and vapor do above and below or left and right irregularly seethe motion, Dust is rapidly rising or falling, and is just rained once running into cloud layer；In addition, also prior natural phenomena, when west wind blows Carry out sandstorm, Hexi Corridor Region ten, which has more than seven times, all rains or snow.

Several natural phenomenas illustrate that dust contributes to the formation of raindrop and snowflake while sleet energy depositing dust above. So, applicant proposed that using dust the natural phenomena of raindrop formation can be helped to realize rain making, i.e.,：

To solve the above problems, a kind of rain making dust of the present invention, the dust is by common soil, sandy soil or both Mixture is ground, dries, sieve, pack is made, wherein, the particle diameter of the dust is no more than 20。

It is corresponding with above-mentioned rain making dust, should present invention also offers a kind of application process of rain making dust Method includes：

（1）The condition of raining of cloud layer near objective area is detected, it is determined that reaching the cloud layer of condition of raining；

（2）When the regional overhead 25 ~ 35min strokes of the cloud layer distance objective for reaching condition of raining, with aircraft or rocket Big gun uniformly sprays the dust to the cloud layer for reaching condition of raining, so that the cloud layer is in the target when realizing rainfall Area overhead.

The present invention has advantages below compared with prior art：

1st, rain making dust is made by common soil or sandy soil in the present invention, on the basis of rain making is realized, due to general Logical soil, sandy soil are all obtained conveniently, and expense is cheap, and extremely suitable large area is used for a long time.In addition, dust drops back into ground with rainfall Face, goes back to nature, and will not produce additional contamination.

2nd, in the present invention rain making dust and reach the cloud layer of condition of raining from touch realize that rainfall needs one section when Between, when applying sprinkling in addition to the reaction time for needing to ensure is 25 ~ 35min, others operation can refer to existing skill The operation of aircraft or rocket gun sprinkling dry ice etc., simple and fast, using convenient are utilized in art.

Embodiment

The present embodiment rain making dust is made by following steps：

（1）Obtain commonly soil and remove after the impurity such as wooden slag, paper scrap, plastics, common soil is ground through ball mill grinding into fine powder While dried.

Common soil referred herein is the soil on ordinary meaning, i.e., it includes sand, light loam and loess embankment, is adopted during making With any all right in these three soil；It is of course also possible to directly using the dust storm in desert, can also be using common soil and dust storm Mixture, the stickiness of dust storm and the common soil of hybrid energy reduction of common soil.

In actual use, ball mill can be dried while being ground to abrasive material, and the temperature of drying can To be located between 105 DEG C ~ 110 DEG C, contained humidity in drying fine powder, it is ensured that mutually scattered between fine particle not to be sticky in together Drying operation can be stopped.

（2）Fine powder is crossed into 700 eye mesh screens, 18 are obtainedThe dust of left and right.

Wherein, the particle diameter of dust of the present invention is no more than 20, according to particle diameter and the corresponding relation of sieve mesh number, can make Sieved with the sieve of 700 mesh and above mesh number.

（3）Powder is allocated, packed.

Corresponding with above-mentioned rain making dust, another embodiment of the present invention also provides a kind of administration of rain making dust Method, the application process comprises the following steps：

（1）The condition of raining of cloud layer near objective area is detected, it is determined that reaching the cloud layer of condition of raining.

Wherein, objective area is the area for needing to carry out rain making, it is contemplated that rain making dust is with reaching rainfall bar The cloud layer of part realizes 25 ~ 35min of rainfall needs reaction time from touching, so, on the basis of the outward flange of objective area, Cloud layer condition of raining detection is carried out in the range of the 25 ~ 35min strokes of distance objective area outward flange.

（2）When the regional overhead 30min strokes of the cloud layer distance objective for reaching condition of raining, with aircraft or rocket gun to Reach that the cloud layer of condition of raining uniformly sprays dust, so that the cloud layer reaches space-time on objective area and realizes rainfall.

Wherein, dust makes water droplet or ice crystal in cloud layer increase to a certain extent by core of dust, drops to ground, is formed Precipitation or snowfall.

It should be strongly noted that present invention focuses on dust is used for into rain making, for applying sprinkling process, removing It is that outside 25 ~ 35min, others operation such as determines to reach the cloud layers of condition of raining to need the reaction time ensured, it is contemplated that Cloud layer reaches the time in objective area overhead, and technology of dust etc. is sprayed to cloud layer and can refer to existing rain making technology, Because existing rain making is the physical characteristic according to different cloud layers, proper moment is selected, is sowed with aircraft, rocket into cloud dry The catalyst such as ice, silver iodide, salt fines, make cloud layer precipitation or increase precipitation, that is, need also exist for finding the cloud for meeting condition of raining Layer rather than at will sprinkling, need also exist for finding accurately the time point of sprinkling dry ice, silver iodide etc., to ensure to be in mesh during cloud layer rainfall The regional overhead of mark, needs also exist for spraying dry ice, silver iodide etc. to cloud layer using aircraft or rocket gun.

It is low due to consuming, it can deploy throughout the year with large area, rainwater is more, vegetation nature riotous growth makes earth desert Change process is able to slow down or part is effected a radical cure, while harm of the arid to agriculture animal husbandry can also be reduced.

In addition, applicant want to combat poison with poison control PM2.5 dust harzards, as long as cloud layer not raining also, at this moment Rain making dust of the present invention can be sprayed with aircraft or rocket gun, rainfall can be formed, rainwater natural energy controls the powder in low latitude Dirt.
