<P>PROBLEM TO BE SOLVED: To provide a defoaming device which can give strong turning flow to a fluid, can reduce the speed attenuation of the turning flow, and can efficiently perform the defoaming in a liquid. <P>SOLUTION: An inner cylinder 3 is formed inside an outer cylinder 1 extending up and down, a lid 5 is formed so as to close an annular space 7 between the outer cylinder and the inner cylinder, an inlet pipe 9 of a fluid is eccentrically formed to the upper end outer periphery of the outer cylinder, an outlet pipe 11 which derives a fluid along the flow of a fluid spirally flowing the annular space turning to the downward from the upside is eccentrically formed to the lower end outer periphery of the outer cylinder, two or more circular or slit-like foam removing holes 13 are formed in the peripheral wall of the inner cylinder, the fluid flowing in the annular space is separated into a liquid and a gas by a centrifugal force, and the gas is caught in the inner cylinder 3 through the foam removing holes 13 and is discharged from the upper part of the inner cylinder 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
