[0021] (Schematic structure of liquid storage system)

[0022] First, refer to figure 1 and figure 2 The liquid storage system according to the present embodiment is described. figure 1 is a schematic diagram of the liquid storage system according to this embodiment, and shows a longitudinal section of the liquid storage tank. figure 2 is a schematic diagram of the liquid storage system according to this embodiment, and shows a cross-section of the liquid storage tank. exist figure 1 and figure 2 In , upward in the vertical direction is indicated by an arrow U, and downward in the vertical direction is indicated by an arrow D.

[0023] like figure 1 and 2 As shown, the liquid storage system according to this embodiment has a liquid storage tank 10 (abbreviated as a storage tank) capable of storing a liquid therein, and a pump for pumping a liquid fuel 20 stored in the storage tank to the outside of the storage tank 10. device 25 (referred to as a liquid pumping devi...

[0076] refer to Image 6 A liquid storage system according to this embodiment, and a method of supplying an incombustible gas to a gas phase space in a storage tank of the liquid storage system are described. Image 6 is a schematic diagram of the liquid storage system according to this embodiment, and shows a longitudinal section of the liquid storage tank. It is to be noted that the same reference numerals are used to designate substantially the same configuration as that of the first embodiment, and description thereof is omitted.

[0077] In an embodiment, the liquid pumping device 25 supplies the liquid fuel 20 stored in the storage tank 10 to the heat engine 2 . The heat engine 2 is a prime mover that converts thermal energy generated by the combustion of the liquid fuel 20 into mechanical energy. The heat engine 2 includes, for example, an internal combustion engine, an external combustion engine, a gas turbine, and a steam turbine. The heat engine 2 is an emergency ...

Abstract

According an embodiment, a liquid storage system comprises a tank for storing liquid fuel, a vent pipe for providing communication between outside of the tank and a gas space above a level of liquid fuel in the tank, a nonflammable gas supplying apparatus for supplying the gas space with nonflammable gases, a pressure control apparatus installed in the vent pipe to operate responsively to the pressure difference between the gas space and atmospheric pressure so as to limit a pressure in the gas space to a predetermined range. The pressure control apparatus introduces ambient air outside the tank into the gas space through the vent pipe when the pressure in the gas space is lower than a predetermined lower limit, and discharge the gas from the gas space out of the tank through the vent pipewhen the pressure in the gas space is higher than a predetermined upper limit.

Description

technical field [0001] Embodiments of the present invention relate to techniques for controlling pressure and oxygen concentration in a gas phase space vertically above a liquid level in a storage tank storing liquid. Background technique [0002] Storage tanks for storing liquids include so-called liquid storage tanks for storing water or flammable oils such as gasoline and diesel. Liquids are stored in such tanks. The liquid is pumped to the outside of the tank through pipes or similar means, if required. Sometimes, in a storage tank, the position of the gas-liquid interface (i.e., the liquid level) drops. The volume of the gas phase space vertically above the liquid level in a tank increases as the liquid level decreases. In the case of a closed space in the storage tank, the pressure in the gas phase space decreases as the liquid level moves vertically downward. When the pressure in the gaseous space reaches a value close to vacuum, it becomes difficult to pump liqui...
