Hard nucleus popular science: Why tank car of lukewarm mountain chamfer can explode twice

Groovy tank car, one kind carries the car of chemical, can understand tank truck temporarily in the article, won't cause what misunderstanding

? ? Your person is mournful message, stage high of big brook of lukewarm mountain of city of stage of Zhejiang of not long ago fast the groovy tank car that assembles oil gas of carrier fluid fossil produces an accident, happening of open fight between factions explodes since, already caused death of more than 10 people, more than 100 people to get hurt, succeeding activity still is undertaking. Huxi releases information into chief editor, say the spot produced explosion 2 times, beyond a lot of in all round film the anticipation of video masses.

Write this article right now, not be to be chased after of purpose duty at who, also not be to want to take person blood steamed bread. About the risk sex that explodes 2 times, although accident of groovy tank car is medium,the example that explodes 2 times cans be found everywhere on the net, but safe conduct propaganda does not return the likelihood to reach the designated position before this. Mend the fold after a sheep is lost still not late, borrow this article to hope everybody can understand somewhat.

Want to say groovy tank car, it must have seeing the name of a think one thinks of its function a jar, accident of this kind of traffic causes explosion, likelihood whether possibly to explode a few times, specific have much risk, with the material that lades inside jar direct and relevant. The liquefied petroleum gas that this accident car lades, namely a kind very incidental the dangerous chemical that explodes 2 times.

Generally speaking, the groovy tank car of normal travel, the environment that inside and outside is relative isolation (have the UniCom such as control a powerful person) , in-house environment is relatively stable. Still lade on the groovy tank car that compares a few familiar model in me have prevent the equipment such as wave board and catenary of electrostatic ground connection to be detonated in order to prevent report of in-house combustible quiet and secluded. But, once car produces an accident to cause rupture of can without lid, so exterior element is contacted with respect to meeting and photograph of liquefied petroleum gas.

Because the density of liquefied petroleum gas after aerification is a bit bigger than air, the liquefied petroleum gas that divulges so can flow to drip and drift in lower part of can without lid, and partial air also can borrow machine and liquefied petroleum gas to mix. This part mixture may burn or trouble spot has other material to may burn, extruding of together with can without lid is out of shape. Pressure of the can without lid below multiple element action changes suddenly, produce first time explosion. This explosion is the explosion with kind of relative lesser power, mix because of right now air and liquefied petroleum gas not complete, a lot of liquefied petroleum gases still are in the condition of pure liquefied petroleum gas, do not share reaction.

Of course, dinkum mechanical collision brings about attaint of can without lid possibly also to make then pelter of force of coal tub internal pressure, become acuteness to cause vapour to explode (whether heating is divisional normal temperature model heat with blaze model the liquefied petroleum gas is destroyed evenly model the fundamental condition that vapour explodes) . Explosion of anyhow first time often spreads out around can without lid. So, this explosion has a very main effect, it is further damage can without lid, gush of liquefied petroleum gas to the middle of sky.

When liquefied petroleum gas and airy mixture ratio exemple enters explosion limit, meet ignition requirement (high temperature, bright fire, electrostatic etc) produce explosion possibly the 2nd times. The liquefied petroleum gas when exploding because of the 2nd and air mix very sufficient, once detonate opposite explosion might,explode than first time likelihood even stronger. Inspect gross to decide, the likelihood is more dangerous. Of course, 2 times explosive may not can happen, the firefighter also can do his utmost to prevent it to happen, it is occasionally floods and fires have no mercy for anybody is not manpower to be able to be held back only.

At the same time I still searched a few literature, about the incidence that the liquefied petroleum gas explodes, did not find kill and wound radius effectively, found the deadly radius below specific requirement only. Light sees this deadly radius know, actually already special far. Want not to get hurt, should be apart from than this apparently far many much.

Some friends may think, he wants to watch the scene of bustle namely, can be in the 2nd times before explosive hind go surrounding view, I think to still be no good. Because pledge in stowage uncertain condition falls, it may not be a liquefied petroleum gas, theoretic have 3 tiny explosion likelihood. Serve as masses eating melon and did not lade inside capable judgement what, and whether can explode 3 times. I think to be sure for the purpose of, still do not go add trouble to. And, a little chemical material can produce many poisonous and harmful gas after explosion, inspiratory later may cause cannot go against the physiology that turn to harm.

And, collect this lively what to do, besides can send a few video, what cannot obtain. Jam possibly instead traffic, allow follow-up rescuing delay, increasing casualties is the serious consequence that produces very likely. Say so, if there is groovy tank car to produce an accident on high speed, should call the police for a short while, it is to restrain oneself to go next the desire of add trouble to, increasing chaos is the hand with our the oldest common people. Of course, although I also adore the sort of heroic man that be ready to help others for a just cause particularly, but this kind of behavior hopes seriously everybody do according to one's abilities, dangerous chemical issue is not the level that ordinary common people can participate in really. In case go in him defect again finally, not be the ending that everybody is willing to see apparently.
