Abstract

PURPOSE:To keep pressure increase low in a container by circulating and discharging the noncondensing gas accumulated in the upper free space in a pressure suppressing chamber into a dry well. CONSTITUTION:The noncondensing gas accumulates in the upper free space of the pressure suppressing chamber 3 when the gas in the dry well 5 flows into a suppression pool 8 through a vent pipe 4. There is a gas discharge chamber 9 enclosed by a partition wall 6 having through-holes 7 in the suppressing chamber 3. The inflow and outflow of liquid are generated through the through-holes 7 by the liquid level oscillation of the pool 8. The compression of the gaseous phase part in the upper part is generated by the rise of the liquid level in the discharge chamber 9 by which the pressure is increased. An exhaust valve 2 opens to discharge the noncondensing gas into the dry well 5 when the pressure increases higher than the pressure of the dry well 5. The pressure in the discharge chamber 9 decreases on lowering of the liquid level. A check valve 11 opens to admit the gas from the suppressing chamber 3 to the discharge chamber 9 when said pressure decreases lower than the pressure of the dry well 5. The amt. of the noncondensing gas to be accumulated is decreased by circulating the noncondensing gas to the dry well 5 from the suppressing chamber 3, by which the pressure increases in the container 1 is kept low.
