PRESSURE DIFFERENCE REDUCING DEVICE FOR REDUCING PRESSURE DIFFERENCE BETWEEN HIGH-TEMPERATURE AND HIGH-PRESSURE FLUID, METHOD OF REDUCING PRESSURE DIFFERENCE BETWEEN HIGH-TEMPERATURE AND HIGH-PRESSURE FLUID USING THE SAME, AND FILTRATION DEVICE EQUIPPED WITH PRESSURE DIFFERENCE REDUCING DEVICE AND FILTRATION METHOD USING THE SAME

摘要

To provide a pressure difference reducing device between high-temperature and high-pressure fluid, a method of reducing a pressure difference between the high-temperature and high-pressure fluid using the same, and a filtration device equipped with the pressure difference reducing device and a filtration method using the same, which can suppress an occurrence of a large pressure difference between the high-temperature and high-pressure fluid over an entire operation time.SOLUTION: A pressure difference reduction device between high-temperature and high-pressure fluid is employed, which operates to reciprocate a partition in an internal space by that an internal space of a cylinder containing the high-temperature and high-pressure fluid is separated into a first fluid containing portion and a second fluid containing portion by a partition fitted so as to be able to reciprocate, and while supplying high-temperature high-pressure fluid to the first fluid containing portion and the second fluid containing portion respectively, and valves of fluid discharge paths respectively connected to the first fluid containing portion and the second fluid containing portion are alternately opened and closed.SELECTED DRAWING: Figure 1
