| 摘要 |
The present invention is a technique related to a cryogenic storage tank capable of storing gas such as nitrogen gas in which a boiling point is very low. A device for recycling boil-off gas generated in the cryogenic storage tank comprises: a cryogenic storage tank in which liquefied gas is stored; a first discharge pipe connected to the lower part of the cryogenic storage tank and in order for liquefied gas to be discharged; a second discharge pipe connected to the upper part of the cryogenic storage tank and in order for liquefied gas in a vapor type to be discharged; and an auto channel switching valve for discharging the liquefied gas or the liquefied gas in the vapor type as being connected to the first discharge pipe and the second discharge pipe and operated according to the pressure of the liquefied gas in the vapor type generated inside the cryogenic storage tank. |
