| 摘要 | PURPOSE:To prevent directly vapor explosion by a superheated and saturated liquid from inducing, by arranging an internal vessel contg. the superheated liquid inside an external pressure vessel at a distance of a surrounding space, which are connected with each other. CONSTITUTION:An internal vessel 3 is arranged inside an external pressure vessel 1 at a distance of a surrounding space 4. Internal pressure for both the vessels becomes identical with each other through an opening 2. Even when breakage is occurred on a part of the external pressure vessel 1, withstanding pressure of the internal vessel 3 against atmospheric pressure is maintained. Then, even when vapor explosion is occurred in the internal vessel 3, neither scattering of broken pieces nor spouting of vapor from a superheated liquid are caused, since the pressure of the surrounding space 4 is about the same as the pressure during a normal operation. In this manner, the vapor explosion of the pressure vessel can be prevented directly and an accident can be reduced to the least. | ||||||
