Title: Gas leakage detecting device for double-shell low temperature tank
Inventor: TOMITA TSUTOMU
IPC: F17C13/12
Filed: 1984-04-10
Abstract: PURPOSE:To surely detect storage gas leakage, by setting the position of gas extraction in a place where leakage gas is liable to stay due to the difference between specific gravity of evaporated storage liquefied gas and that of seal gas. CONSTITUTION:In the case of that the specific gravity of leakage gas is greater than that of seal gas in a cold insulating layer, the positions of gas extraction are set, respectively at both of lowest point 10 on the outer surface of an inner tank 4 in a cold insulating layer and a point 11 slightly above the connecting section between the top end of an inner tank side plate and a dome-like inner tank roof 6. Leakage gas from the inner tank has a specific gravity larger than that of nitrogen gas, and therefore, even if gas leaks from any point on the inner tank roof 6, leakage gas flows along the upper surface of the dome-like shape roof toward the outer periphery thereof, and flows down along the outer surface of the inner tank side plate 4 to the bottom where leakage gas stays. Accordingly, leakage gas is mixed into gas taken in from the gas extraction position set on the bottom and is therefore extracted and detected.
