Title:
FUEL RECOVERY DEVICE IN CASSETTE GAS CYLINDER
Document Type and Number:
Japanese Patent JP2020180689
Kind Code:
A
Abstract:
To solve the problem that in the future, a large amount of cassette gas cylinders will be stockpiled, and most of them will expire without being used.SOLUTION: When a stem of a cassette gas cylinder is pushed into a holder 21, a passage opens, and a gas outlet pipe is installed in a sideways posture so that a gas introduction end faces downward, so that the gas introduction end is in a state of being thrust into a liquid layer of liquefied gas fuel. With a suction effect of a vacuum pump 73, the liquefied gas fuel is sucked from the gas introduction end in a liquefied state, and recovered in a recovery cylinder 55. The liquefied gas fuel filled in the cassette gas cylinder can be efficiently extracted and recovered in a short time. Further, since gas is not released into the air, treatment can proceed safely.SELECTED DRAWING: Figure 1
