NOVELTY - Liquefied natural gas re-condensing device comprises a low pressure container. The middle of the low pressure container is provided with filler. The upper part of container with filler is provided with a liquefied natural gas inlet and a high pressure nitrogen gas inlet. The container at the tank bottom is provided with a liquefied natural gas outlet. The liquefied natural gas enters into the upper part of filler from a re-condenser through a liquefied natural gas inlet (1). The evaporated gas from the lower part of filler enters into re-condenser through an evaporation gas inlet (2).    USE - Used as a liquefied natural gas re-condensing device.    ADVANTAGE - The device achieves the effect of reducing noise, vibration, and downstream external damage of output pump, and maintains stabilized pressure inside the container.    DETAILED DESCRIPTION - Liquefied natural gas re-condensing device comprises a low pressure container. The middle of the low pressure container is provided with filler. The upper part of the container with filler is provided with a liquefied natural gas inlet and a high pressure nitrogen gas inlet. The container at the tank bottom is provided with a liquefied natural gas outlet. The liquefied natural gas enters into the upper part of the filler from a re-condenser through a liquefied natural gas inlet (1). The evaporated gas from the lower part of the filler enters into the re-condenser through an evaporation gas inlet (2). A certain pressure of the inert gas enters the filler through an inert gas inlet (3). The evaporated gas and liquefied natural gas in the filler are exposed for liquefaction. The liquefied natural gas is discharged from the lower part of the re-condenser into a high pressure pump through the liquefied natural gas outlet (5).
