ある。(Prior Art) As shown in FIG. 2, in a circulating hot water supply system, hot water heated by a heater 2 in a hot water storage tank 1 is forcibly circulated in the direction of the arrow by a pump 3, and is supplied from a hot water tap 5 of a circulation pipe 4. The used amount is replenished from the elevated water tank 6 through the water supply pipe 7.

In the figure, 1 is a hot water storage tank, 3 is a pump, 4 is a circulation pipe, 6 is an elevated water tank, and 7 is a water supply pipe. Reference numeral 8 denotes a bubble separator installed in the middle of the circulation pipe 4, which includes a hollow large-diameter portion 8a, an air cushion tube 8b provided on the upper surface of the hollow large-diameter portion 8a, and an upper plate of the cushion tube 8b that can be moved up and down. It consists of an air vent pipe 8C provided in the air vent tube 8C.

きないものである。(Utility Model Publication No. 55-91902) As another example of the conventional deaerator, as shown in FIG. There is an air separation device 14 which is provided with an outflow pipe 13 through which the liquid exits approximately tangentially. In this air separation device 14, the air in the liquid that has flowed into the tank 1° is separated while swirling and descending along the inner wall of the tank and accumulates in the upper part of the tank 10. When a certain amount has accumulated, the air is removed from the air vent 11. This is what 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 hot water cannot be degassed because the hollow large diameter portion 8a is sealed and the pressure inside the air cushion cylinder 8b is high. It is something that cannot be done.

この為、循環配管の途中に本格的な脱気器を設けること
が考えられるが、完全脱気の為には、脱気器が大型化し
、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 for complete deaeration, the deaerator becomes large and requires a large installation space as a circulating hot water supply equipment. Moreover, the cost is extremely high and it is not suitable for practical use.

態を保持できる。(Function) As mentioned above, hot water diverted from the hot water storage tank to the sub-circulation circuit is sprayed and deaerated in an open deaeration box, so corrosive gases such as oxygen and chlorine dissolved in the hot water are completely removed. It is degassed and released into the atmosphere. The degassed water is returned to the hot water storage tank by a push pump. Since this action is repeated and repeated, the water in the hot water storage tank and the water flowing through the main circulation circuit are gradually deaerated, and even when hot water is used and water is replenished from an elevated water tank, By repeating and continuously performing the above actions, the amount of corrosive gas necessary for corrosion prevention is degassed, and in response to load fluctuations in hot water supply, the hot water storage tank is transferred to a sub-circulation circuit independent of the main circulation circuit. Since the water is diverted and degassed by spraying in the open deaeration box, there is little influence on the main circulation circuit, there is no shortage of hot water, and extremely stable operating conditions can be maintained.
