BUBBLE DETECTION DEVICE AND CONDENSATION EQUIPMENT USING BUBBLE DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a bubble detection device capable of detecting bubbles existing in a liquid with good sensitivity, and to provide condensation equipment using the bubble detection device.;SOLUTION: A bubble detection device 1 is provided in a flow passage in which a liquid which has the possibility of containing bubbles flows, and detects bubbles contained in the liquid. The bubble detection device includes: a vertical container 3 in which a supply pipe 9 for supplying a liquid is connected at a side wall part, and in which a discharge pipe 11 for discharging the liquid is connected at a lower part; a liquid return pipe 5 which is provided at an upper part of the vertical container 3 and which always returns the liquid which has flowed in to a liquid source; and a differential pressure gauge 7 for detecting a differential pressure in a region where bubbles can exist in the vertical container 3 or at one part of the vertical container 3 and the liquid return pipe 5.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
