ABSTRACT:
The present invention provides a deaerator and a deaerating method which enable the continuous deaeration of a liquid at a low cost. That is, with respect to a pipe which supplies a fluid by a supply means, a rip-out portion which rips out a fluid from an inner peripheral surface of the pipe is provided at a predetermined position in the inside of the pipe, and the fluid is supplied at a predetermined flow rate by a flow control means which adjusts the flow rate of the liquid which is supplied through the pipe so as to form a cavity on a downstream side of the rip-out portion. A through hole which communicates with the cavity is formed in the pipe, and deaeration of the liquid is performed by exhausting gases in the inside of the cavity by suction means such as a vacuum pump via the through hole.
