ものである。(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 amount used is replenished from 4 fl s of elevated water through the water supply pipe 7.
このような循環式給湯設備では、渦中に含まれている酸

設けられる。In such circulating hot water equipment, water often leaks due to corrosion caused by gases such as oxygen and chlorine contained in the whirlpool, and for this reason, various deaerators are provided to remove corrosive gases.

設けた抜気管8Cとより成るものである。An example of a conventional degassing device is a bubble separator shown in FIG. 3. In FIG. 6, 1 is a hot water storage D, 3 is a pump, 4 is a circulation pipe, 6 is an elevated water 4L, and 7 is a water supply pipe. 8 is a bubble separator installed in the middle of the circulation pipe 4, which includes a hollow large diameter section 8a;
Air cushion cylinder 8 provided on the upper surface of this hollow large diameter 18a
b, and an air vent pipe 8C provided on the upper plate of the air cushion cylinder 8b so as to be movable up and down.

上昇させることにより大気中に放出されるものである。In this bubble separator 8, when the bow enters the hollow large-diameter portion 8a, the flow velocity slows down, and the bubbles in the hot water are separated and accumulate in the cushion cylinder 8b, and this accumulated gas causes the air vent pipe 8C to rise. It is released into the atmosphere as a result.

b内の圧力が高いので、脱気できないものである。(Refer to Utility Model Publication No. 55-91902.) As another example of the conventional deaerator, an air vent 11 is provided at the top of a cylindrical tank 10 as shown in FIG. There is an air separation device 14 which is provided with an inlet pipe 12 through which liquid flows in substantially tangentially to the inner surface of the tank, and an outflow pipe 13 through which liquid flows out substantially tangentially to the inner surface of the tank from the lower side wall of the tank 10. This air separating device 14 separates air from the liquid that flows 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. 11, which is released into the atmosphere. (Refer to Utility Model Application No. 59-127708.) (Problems to be Solved by the Invention) By the way, the bubble separator 8 shown in FIG. The large air bubbles that originally existed in the pipe can be separated in the hollow large diameter part 8a, but the gases such as oxygen and chlorine dissolved in the vortex can be removed from the air cushion tube 8 because the hollow large diameter part 8a is sealed.
Since the pressure inside b is high, it cannot be degassed.

じることがありうる。For this reason, it is possible to install a full-fledged open-type deaerator in the middle of the circulation piping so that it does not interfere with hot water supply, but in order to achieve complete deaeration, the deaerator needs to be large, and the circulating hot water supply system The equipment requires a large installation space and is extremely expensive, making it impractical. Furthermore, in the case of a small deaerator, the amount of hot water soaked by the deaerator is regulated when the load fluctuates (intensive use of t'jjJ), so a shortage of hot water may occur.

不足を生じる心配が無い。(Function) According to the open type deaerator with the above configuration, the circulation circuit is circulated T!
A part of the flowing hot water is diverted to a bypass circuit, and the rest enters a deaeration circuit, where it is sprayed and deaerated in an open spray deaeration box, removing oxygen, chlorine, etc. dissolved in the vortex. Corrosive gases are completely degassed and released into the atmosphere. After deaeration, the hot water is returned to the circulation circuit through the bypass circuit by a forced pump, so that the amount of corrosive gas necessary to prevent corrosion is removed from the hot water flowing through the circulation circuit, and the hot water flows through the circulation circuit while the hot water is not in use. Corrosive gases such as oxygen and chlorine in the vortex gradually become diluted. In addition, even when hot water is used and water is supplied to the circulation circuit from an elevated water tank, the hot water flowing through the circulation circuit is always sprayed and degassed in the open spray deaeration box of the deaeration circuit. Since it returns to the post-circulation circuit, the amount of corrosive gas required to prevent corrosion can be degassed, and load fluctuations (intensive use of water) can be removed.
Since the flow of hot water is guaranteed by the bypass circuit, there is no need to worry about insufficient hot water.

スが無くなるので、確実に腐食が防止される。The operation of the open type deaerator constructed as above will be explained. The hot water heated by the heating heater 16 in the storage 44Hs leaves the hot water storage tank 15 and flows through the circulation path 17, one part of the water is diverted to the bypass circuit 20, and the rest is sent to the branch introduction pipe 22 of the four degassing paths 22. a, and from the spray n nozzle 25 in the open spray deaeration box 23, I+! 1n, corrosive gases such as oxygen and chlorine dissolved in the hot water are completely degassed and released into the atmosphere through the ventilation pipe 26, and the degassed hot water is stored in the open spray degassing box 23. is temporarily stored. and outlet pipe 2
The hot water is returned to the circulation circuit 17 by the forced pump 24 of 2b, combined with the hot water circulating through the circulation circuit 17, and sent into the hot water storage tank 15 by the forced pump 19, where it is heated again to a constant temperature by the heating heater 16. It flows into the post-circulation circuit 17. Thereafter, the above action is reversed, and corrosive gases such as oxygen and chlorine dissolved in the hot water circulating through the circulation circuit 17 are degassed, and the vortex corrodes the components of the circulating hot water supply equipment. Corrosion is reliably prevented because the amount of corrosive gases such as oxygen and chlorine required for
