Abstract

PURPOSE:To make pressures in inner and outer tanks equal and prevent buckling of the inner tank by providing an emergency communication device which is closed in normal operation and opened to communicate atmospheres in the inner and outer tanks by the effort of an atmosphere in the outer tank whose pressure is increased more than that in the inner tank when it is damaged. CONSTITUTION:A roof 11a of an inner tank 11 and a wall 12a of an outer tank 12 are connected by an inverse U-shaped pipe 13. The pipe 13 has at the perpendicular part an emergency opening valve 16 which is kept closed in the normal state. If a low temperature liquid flows out on account of an accident such as a damage of the inner tank 11, a pressure P1 in the inner tank is reduced to a negative pressure because of reduction of liquid level in the inner tank 11 while the other pressure P2 in the outer tank 12 is increased because of rise of liquid level and atomization of a low temperature liquid. The pressures may make a relation of P2>P1. If the differential pressure exceeds a set value, a pressure controller 18 is actuated to open the emergency opening valve 16 so that the atmospheres in the inner and outer tanks may be communicated by the pipe 13 to fall in the relation of P1=P2, thereby preventing the buckling of the inner tank 11.

Due to the increase in pressure due to vaporization (boil-off) of the liquid that entered the tank, there is a possibility that y Pl<' /all G P* >'''/al G and P+ <pt. , the inner tank will be pushed from the outside by external pressure, and unless some measure is taken against this, normally △p=p.

汚損を招く問題点がある。If the inner tank roof or 1ill plate buckles in this way, even if the damage is initially small, it will lead to large-scale damage, leading to major damage to the inner tank → large amount of liquid leaking → destruction to the outer tank → a catastrophic disaster. figure,
Repairs are also difficult.In contrast, the protection measures for conventional double-shell cryogenic tanks are as shown in Figures 1 and 1-7. Safety valves (31 pcs., outer tank (2)

It was operated individually. This countermeasure is designed to prevent damage to the inner tank.In terms of capacity, it is not possible to deal with a large amount of liquid released from the inner tank.

Since the safety valve 1 and the outer tank safety valve (4) are made separately, there is a delay in operation, which is not necessarily a desirable safety measure.

It is something to do.

Make it conductive. A valve α4, which is normally open, is installed on both vertical sides of this pipe (13). An emergency release valve αe (emergency communication device), which is normally closed, is provided between the α port I and the valves I and α9. Inner tank internal pressure P1 and outer tank internal pressure P are applied to this emergency release valve Oe.

When low-temperature liquid flows out due to a breakage accident, the liquid level in the inner tank αυ drops and P becomes negative pressure, and conversely, the outer tank (1
The pressure P inside 3 increases due to the rise in the liquid level and the vaporization of the low temperature liquid, and becomes pp. This pressure difference is immediately detected by the differential pressure transmitter Q7)K, and when the differential pressure exceeds the set value, a signal from the differential pressure transmitter a71 is transmitted to the pressure controller Ql.
The emergency release valve αe is opened by the operation of the pressure controller Q8, and the inner tank internal surrounding air and the outer tank internal surrounding air are brought into conduction by the knob Q3, and the PH: Pl door j is transmitted.
ri,p,:>p, phenomenon, t,ru inner tank (11+) buckling is prevented, and outside air is sucked into the inner tank atmosphere,
There is also no risk of explosion due to the release of flammable gas from the outer tank to the outside.
