Description
Technical field
The invention belongs to emergency rescue technology field, is related to a kind of method for making chemical powder be quickly dissolved in water.
Background technology
According to the data of announcement, China, every year up to 200,000,000 tons, is related to more than 3000 by the hazardous chemical material of highway transportation
A kind, including more than 100,000,000 tons of inflammable and explosive oil product, more than 400 ten thousand tons of liquid chlorine, more than 300 ten thousand tons of liquefied ammonia, and hypertoxic cyanide number
100000 tons etc..120,000, the vehicle of peril of transportation chemicals cargo is engaged in, wherein transporting the tank cars of all kinds of liquid gas up to 1.47
Ten thousand.Most of hazardous chemical material is related to trans-regional, long range, large-tonnage transport.Hazardous chemical production, storage,
In transport, business process, hundreds of leakage accidents occur every year, total number of accident is accounted in the leakage accident ratio that transit link occurs
About 1/3.The dangerous chemical leakage accident occurred in transport can cause interruption of communication, wherein the flammable and explosive substance leaked out
Easily trigger big fire and explosion；The toxic and harmful gas leaked out, including the toxic and harmful gas that hazardous chemical evaporates out, prestige
The life security of the people is coerced, also needs to shift wind direction downstream resident sometimes.
For example, on March 29th, 2005, Beijing-Shanghai high speed Jiangsu Huaian 103 km of section uplink places generation automobile crash thing together
Therefore cause a groove tank car for being loaded with about 35t liquid chlorines that chlorine leakage occurs.The disperse with the wind of the chlorine of leakage, involves Huaiyin, Lianshui
11,3 small towns administrative village of 2 counties and districts, causes 29 people to be poisoned to death, and 456 people poisoning hospitalization, 1867 people's outpatient services, which are stayed, to be controlled,
More than 10000 villager is forced evacuation transfer, and nearly 9000 (only) domestic animals, poultry are dead, more than 20,000 mu crops total crop failure or impaired.
It is eliminate danger as early as possible destruction of the chemical leakage accident to ecological environment and the threat to life security, it is necessary to adjust
