A leakage self-rescue container for stocking dangerous chemicals
comprises a first container for stocking dangerous chemicals, and a second
container
installed and fixed in the first container. The second container contains a
substantially
harmless liquefied gas and has an opening, which controllably communicates
with the
external environment. Where dangerous chemical products leak due to accidents
or
are threatened by high temperature, the liquefied gas in the second container
releases
so that the temperature in the first container decreases and thereby the
pressure in the
first container reduces so as to avoid the leakage or explosion caused by
overpressure,
or to increase the viscosity of the dangerous chemicals to reduce the leakage
rate
when the leakage occurs and to obtain valuable time for more effective rescue.
L'invention porte sur un contenant auto-assisté contre les fuites pour stocker des produits chimiques dangereux, lequel contenant comprend un premier contenant (101, 201) pour stocker des produits chimiques dangereux, et un second contenant (103, 203) qui est installé et fixé à l'intérieur du premier contenant (101, 201), le second contenant (103, 203) contenant le gaz liquéfié fondamentalement non dangereux (105, 205) et comportant des ouvertures ouvertes d'une façon réglable sur l'environnement externe. Lorsque les produits chimiques dangereux se trouvent répandus par accident ou sont menacés par une température élevée, il est possible, grâce à la libération du gaz liquéfié dans le second contenant (103, 203), de réduire la température dans le premier contenant (101, 201), et de réduire ainsi la pression dans le premier contenant (101, 201), de façon à éviter une fuite ou une explosion provoquée par une surpression, ou, lorsque la fuite s'est produite, il est possible grâce à l'augmentation de la viscosité du produit dangereux, de réduire le débit de fuite dans le but de gagner un temps précieux avant larrivées des secours pour une lutte plus efficace.
