とする。Alternatively, there was a problem that an excessive pressure rise in the deaeration tank (2) was caused. In addition, when heating is insufficient, the boiling point may not be reached and there is a risk of insufficient deaeration. Also, the deaeration tank (2)
It is also possible to control the heating of water by the temperature in the degassing tank (2), but since the control μ is around the boiling point of water,
There was a problem that proper heating control was difficult.This invention was made to solve the above problems. The purpose is to obtain a water treatment device that can perform the following steps.

正圧に保つ絞９弁である。In FIG. 1, (2) and (4) are the same as the configuration of the conventional device described above. (5) is a water seal serving as pressure regulating means, and the water seal (5) and deaeration tank (2) are connected through a conduit (6). (7) is a temperature element that detects the temperature inside the degassing tank (2), and (8) is a heater (4) that heats depending on the temperature detected by this temperature element (7).

) is a heating control means that is controlled by a signal from the temperature controller (8) and controls the amount of heating of the heating heater (4). α1 is the degassing tank (2) K connected evaporation tube, αB
are nine throttle valves arranged on this evaporation pipe 00 to maintain the internal pressure of the deaeration tank (2) at a positive pressure.

Set to a positive pressure of about ommAq. The saturated steam temperature corresponding to this pressure is approximately 102.5°C. In this state, the temperature setting of the temperature controller (8) is set to loo''c.

ある一定の圧力内に抑えることができる。The temperature of the water to be treated in the deaeration tank (2) is raised by the heating heater (4), and when the temperature reaches 100°C, the temperature element (7) is heated.
), the heating control means (9) is operated by the temperature controller (8), and the temperature is maintained at a constant temperature of 100°C. In other words, since the boiling temperature of the deaeration tank (2) at an internal pressure of 1000100O is 102.5°C, it is possible to control the temperature at 100°C. The above wasteful consumption of heat can be prevented. If throttle 9 valve 0 is not installed, the internal pressure of the deaeration tank (2) will be atmospheric pressure, so if the temperature setting of the temperature controller (8) is set to ``loo''c, the water to be treated will start boiling at 100℃, and the heating heater will start boiling. (4) may not stop and waste heat.In this case, setting the temperature to, for example, 97°C may be an option.
At this temperature, a sufficient deaeration effect cannot be obtained. In addition, in the event that the internal pressure of the insufflation tank (2) rises excessively, the pressure will be adjusted by the water seal (5) connected via the conduit (6).
It can be kept within a certain pressure.

ができるとともに必要以上の無駄な熱量消費を防ぐこと
ができる。The heating control means (9) may operate directly upon detection by the pressure transmitter (2). In FIG. 2, for example, the pressure-h controller α9 is set to 500 mmAq. The water to be treated is heated by the heater (4) and begins to boil. Although it is released from the evaporation pipe 00, it is suppressed by the throttle valve α, so that the internal pressure of the degassing tank (2) increases. As the pressure increases, the boiling point of the water to be treated rises, and the liquid temperature also rises. When the internal pressure of the degassing tank (2) reaches 500 mmAq, the heating control means (9) is activated by the pressure transmitter (2) and the pressure controller α9 to maintain the pressure of 500 mmAq. That is, since the boiling temperature of 500 mmAq is 101° C., it is possible to obtain the required deaeration effect corresponding to the same temperature, and to prevent unnecessary wasted heat consumption.

。In addition, in the above embodiment, a water seal (5) is used as a pressure regulating means to prevent an excessive rise in pressure in the deaeration tank (2), but as shown in Fig. 3, a U-shaped trap is used as a pressure regulating means. A similar effect can be obtained even if (to) is used.

同様である。The water seal (5) may be provided with a water level transmitter α4. That is, in FIG. 4, the pressure in the degassing tank (2) is detected by the water level transmitter α4 attached to the water seal (5), and the heating control means (9) K is detected via the water level controller α0. Alternatively, the heating amount of the heater (4) may be controlled. If the water level transmitter α4) is set to 50
If it is set to operate when it is lowered by 0 mm, the operation inside the degassing tank (2) is the same as when the pressure web Ia surface is retracted.

By providing the pressure adjustment means, it is possible to obtain a water treatment device that can perform deaeration processing by adjusting the pressure in the deaeration tank without inputting wasteful heat, and can perform effective deaeration processing. .
