<p>PURPOSE:To prevent the generation of gaysering by providing a liquid mixing gas injection opening at every geyseriny generating limit liquid column height and controlling the flow of the mixed gas by means of the incline of temperature in a pipe shaft direction. CONSTITUTION:Units 11 are constituted by providing the vertical portion of the receiving piping 2 of an LNG tank 1 at every geysering generation minimum length A. And a liquid mixing injection opening 12 is formed at the lower end portion of each unit 11. The detection signal of the temperature detector 14 of each unit 11 is arranged to be inputted to a temperature difference operator 15 which acts as a controller. A boiling point curve according to a liquid column height within the piping 2 is inputted beforehand at this temperature difference operator 15. When the actually measured value of each point approaches to a boiling point curve at its point, a signal is sent to a flow control valve 13, and a mixing gas is injected from the injection opening 12 and a liquid is mixed.</p> |
