PURPOSE:To release a gas in hot water by providing a flow regulating mechanism to keep a sufficient space in the titled deaerator, furnishing a nozzle to atomize hot water to be fed into the space and providing a filter for collecting fine bubbles before a supply hot water outlet. CONSTITUTION:Hot water from an inlet 2 is atomized 4 by a nozzle 3 equipped with an opening and closing mechanism and discharged into a space in the main body 1. The water level in the space is kept at a fixed level 6 by a flow regulator 5 and regulated not to exceed the high level 7. The pressure in the space is regulated at a value of about 0kg/cm<2> atmospheric pressure through a deaeration pipe 10. Since 5ppm excess oxygen remains in hot water at 55 deg.C, the excess oxygen is rapidly discharged to the outside from the atomized hot water. The fine bubbles remaining in hot water below the fixed water level 6 are collected by a filter 11 and discharged from a suction port 8 to a circulating pipeline through a discharge port 9. Consequently, gaseous oxygen, chlorine, etc., contained in hot water is discharged to the outside and the corrosion of metal is prevented. |
