できないものである。In this bubble separator 8, when hot water enters the hollow large-diameter portion 8a, the flow rate slows down, and the bubbles in the mountain are separated and accumulated in the cushion cylinder 8b, and the accumulated gas is removed by raising the air vent pipe 8c. It is released into the atmosphere. (
(See Japanese Utility Model Publication No. 55-91902.) As another example of a conventional deaerator, as shown in FIG. There is an air separation device 14 which is provided with an inlet pipe 12 through which liquid flows in approximately tangentially to the tank 10, and an outflow pipe 13 through which liquid flows out approximately tangentially from the lower side wall of the tank 10 to the inner surface of the tank. In this air separation device 14, the air in the liquid is separated from the liquid flowing into the tank 10 as it swirls and descends along the inner wall of the tank and accumulates in the upper part of the tank 10. When a certain amount has accumulated, air is released from the air vent 11. It is released into the atmosphere. (Refer to Utility Model Application Publication No. 59-127708) (Problems to be Solved by the Invention) By the way, the bubble separator 8 shown in FIG. Although large bubbles can be separated, gases such as oxygen and chlorine brought in by the water supply and dissolved in the vortex cannot be degassed because the hollow large diameter part Bah is sealed and the pressure inside the air cooker cylinder 8b is high. It is something.

循環式給湯設備としては大きな設置スペースを必要とし
、且つ著しくコスト高となって、実用向きではない。For this reason, it is possible to install a full-scale deaerator in the middle of the circulation piping, but the deaerator will be large in order to achieve complete deaeration.
Circulating hot water supply equipment requires a large installation space and is extremely expensive, making it impractical.

After deaeration, the hot water is returned to the circulation circuit by a push pump, so the hot water flowing through the circulation circuit is deaerated as necessary, and corrosive gases such as oxygen and chlorine in the hot water flowing through the circulation circuit are gradually removed while the hot water is not being used. Even if hot water is used and water is supplied to the circulation circuit from an elevated water phase, the water flowing through the circulation circuit must be diverted to the bypass circuit and stored in an open deaeration box. Since the spray is degassed and returned to the circulation circuit after deaeration, the amount of corrosive gas required for corrosion prevention can be degassed, and the hot water supply follows the load fluctuations well.

ガスが無くなるので、確実に腐食が防止される。This divided water flows through the branch introduction pipe 20m and is sprayed from the spray nozzle 22 in the open deaeration box 21, and corrosive gases such as oxygen and chlorine dissolved in the vortex are completely degassed. The hot water after deaeration is temporarily stored in the open deaeration box 21. Then, the hot water is returned to the upstream of the forced pump 19 of the circulation circuit 17 through the bypass circuit 20 by the forced pump 24 of the outlet pipe 20b, and is combined with the hot water circulating in the circulation circuit 17, and is pumped into the hot water storage 4ff15 by the forced pump 19. The water is sent there, is heated again to a certain temperature by the heater 16, flows into the circulation circuit 17, and is branched into the bypass circuit 20 from the middle. Thereafter, the above process is repeated, and corrosive gases such as oxygen and chlorine dissolved in the water circulating through the circulation circuit 17 are degassed, and the vortex contains gases necessary to corrode the components of the circulating hot water supply equipment. Since large amounts of corrosive gases such as oxygen and chlorine are eliminated, corrosion is reliably prevented.
