ことになり、赤水の発生を防止することができる。2. Description of the Related Art The generation of red water in a water supply pipe of a building or the like is caused by red rust due to corrosion of the piping system. In recent years, as a measure for preventing the red water, a pipe using a vacuum deaerator, which is highly safe and low cost. Corrosion prevention device is used.
For example, although the pipe corrosion prevention device as shown in FIG. 2 is adopted, in the same drawing, 31 is an elevated water tank, 32 is a load, 33 is a water distribution line, 34 is a deaeration device, and 35 is a deaeration line. . In these configurations, by the action of the deaerating device 34, the deaerating operation is performed while circulating the water in the elevated water tank 31 through the deaerating line 35, and if necessary, the water distribution line 3
Water is supplied to the load 32 through 3.
Therefore, the water distribution line 33 is constantly filled with degassed water, and the generation of red water can be prevented.

上問題となる。However, recently, the site area is small,
Further, since the air-conditioning equipment is installed on the rooftop, it is often impossible to secure the installation space for the deaerator 34. Therefore, as shown in FIG. 3, the deaerator 34 is installed in an existing water receiving tank 36 such as underground. Will be installed in. By the way, in this water receiving tank 36, the capacity of the water tank and the flow rate of the pumping pump 37 are set by predicting the maximum amount of water used in a building or the like.
The processing capacity of the deaerator 34 connected to this is also required to have a capacity equivalent to these, so that the cost is greatly increased as compared with the conventional deaerator corresponding to the average amount of water used.
Note that if the conventional degassing device with the same capacity is used as it is, the flow rate of the pumping pump 37 will be higher, so the degassing process of the treated water will not be sufficient, and the degassing concentration will be higher than the prescribed degassing concentration.

い。According to the present invention, the raw water stored in the water receiving tank is degassed by the degassing device, a predetermined amount of this degassed water is stored in the degassing water tank, and then the pumping pump is driven to send the water to the elevated water tank. At the same time, deaerated water is supplied to the deaerated water tank. Then, when a load is generated and the deaerated water in the elevated water tank is distributed to a predetermined water level,
The pumping pump is driven for a relatively short time to feed the deaerated water from the deaerated water tank to the elevated water tank, while the deaerated water tank is driven for a little longer time to replenish the deaerated water. Therefore, since degassed water of a predetermined concentration is always stored in the degassed water tank,
The capacity of the deaerator may be the same as the conventional one.
In addition, if the pumping pump is frequently operated due to an abnormal increase in load and the supply of degassed water is insufficient, water is urgently supplied from the bypass circuit to the degassed water tank, so water is not cut off.

According to the above-mentioned arrangement, the load 2 is generated and the deaerated water is supplied from the elevated water tank 3 through the water distribution line 4. However, when the water is supplied to a predetermined water level, the ball tap type water level adjusting device 17 operates and the controller 14 is activated. The pumping pump 7 is turned on to feed the deaerated water from the deaerated water tank 5 to the elevated water tank 3. On the other hand, when the degassed water in the degassed water tank 5 drops to a predetermined water level, the ball tap type water level adjusting device 17 operates and drives the degassing device 8 via the controller 14 to remove the degassed water in the degassing water tank 5. Replenish up to the prescribed water level. Similarly, when the raw water in the water receiving tank 10 drops to a predetermined water level, the solenoid valve 21 is opened to receive the raw water.
It should be noted that the load 2 is temporarily increased and the supply of deaerated water to the elevated water tank 3 exceeds the capacity of the deaeration device 8, and the water level of the deaerated water tank 5 is the lower limit of the low water level detection sensor 13. When the temperature drops to 0, the sensor 13 operates, the solenoid valve 16 is opened via the controller 14, and water is urgently supplied from the water receiving tank 10 to the ball tap type water level adjusting device 17 via the bypass circuit 12 to respond. I am trying to do it. Therefore, the mixed water of deaerated water and raw water is distributed, but since it is a temporary phenomenon, red rust does not occur in the piping system.

きるので便利である。Since the present invention has the water distribution system as described above, the pumping pump having a large flow rate can be dealt with by the degassed water stored in the degassing water tank. Since the degassed water having a predetermined concentration is supplied to the degassing water tank in sequence, it is not necessary to install a large capacity degassing device.
Therefore, since the deaerator, which has a relatively small capacity and is suitable for the average amount of water used, can be applied, the facility cost can be greatly reduced. Further, it is convenient because water can be supplied through the bypass circuit to deal with a temporary increase in load.
