るようにしている。Generally, power generation equipment in a thermal power plant or a nuclear power plant has conventionally had a block configuration as shown in FIG. That is, it has a turbine generator 3 that is integrally formed with a turbine 1 and a generator 2, and a steam generator 4 and a condenser 5 form a closed pipe line in this turbine generator 3. A pump 6 is arranged between the steam generator 4 and the condenser 5 to connect it, and a water intake T provided in the shallow sea near the power plant is connected to the condenser 5 via a pump 8. It is the composition. In the case of this configuration, the high temperature and high pressure steam obtained from the steam generator 4 is sent to the turbine generator 3 to do work, and then the condenser 5
In this condenser 5, the water intake T is guided by the pump 8.
It exchanges heat with the seawater pumped up from the tank, condenses, and returns to the steam generator 4 again by the pump 6. On the other hand, the seawater after heat exchange is discharged into the sea away from the water intake lower.

た。In this way, in power plants, seawater is used as a cooling medium to condense steam after work is done.
The temperature of the waste water discharged from the condenser after heat exchange is usually 5℃~
The temperature would be raised to about 10°C, and the discharge of this heated wastewater into seawater had the disadvantage of causing environmental problems.

整を行なうようにしたものである。In view of these conventional drawbacks, this invention detects the temperature difference between the temperature of the waste water discharged from the condenser and the seawater temperature at the part where this wastewater is discharged, that is, the temperature of the seawater at the discharge part. Degree to which it does not cause environmental problems 9 For example 2
In order to control the temperature so that it does not rise above ℃, either pump up seawater from the deep sea, where the temperature is always sufficiently low compared to the seawater temperature in the shallow sea, and mix this seawater from the deep sea with seawater from the shallow sea. Alternatively, it is mixed into heated wastewater to adjust the temperature of the wastewater.
以下、この発明に係わる蒸気復水装置の実施例につき、
第２図および第３図を参照して詳細に説明する。Examples of the steam condensing device according to the present invention will be described below.
This will be explained in detail with reference to FIGS. 2 and 3.

維持されるようにしたものである。In the example shown in Figure 2, seawater from the deep sea is mixed with seawater from the shallow sea to adjust the wastewater temperature, and in the example shown in Figure 3, seawater from the deep sea is further mixed into the wastewater to adjust the temperature of the wastewater in the same way. This is the case. In each of these figures, the same reference numerals as in the above-mentioned Fig. 1 indicate the same or corresponding parts. First, in the embodiment shown in Fig. 2, as a water supply system to the condenser 5, water is taken into the conventional shallow sea. An open/close control pulp 9 is inserted into a system of a pump 8 having a lower shaft, and a system of a pump 11 and an open/close control pulp 12 is branched from the same system and has a water intake 10 in the deep sea, which is always sufficiently lower in temperature than the shallow sea. In addition, temperature detectors 1 are installed on the drainage side of the condenser 5 and in the shallow sea near the water intake T.
3.14, and each of these temperature detectors 13.14
A temperature difference detector 15 is provided to detect the temperature difference between the opening and closing control pulps 9.
, 12 are controlled to open and close so that the difference in temperature detected by each temperature detector 13, 14 is maintained as small as possible, for example, at least ±2° C. or less.

御するのである。That is, specifically, the temperature detector 13. In other words, when the temperature on the discharge side of the condenser 5 rises higher than the temperature of the seawater in the shallow sea near the water intake T by the temperature detector 14, the temperature difference between the two is detected by the detector 15. By using the detection power, the opening degree of the opening/closing control pulp 9 is reduced to reduce the amount of water taken from the shallow sea, and at the same time, the opening degree of the opening/closing control pulp 12 is increased to increase the amount of water taken from the deep sea where the temperature is low. By doing so, the temperature of the water supplied to the condenser 5, and therefore the relative temperature of the condenser 5.
and also temperature sensor 13
When the temperature of the tank falls below the temperature of the temperature detector 14, the system operates in the opposite manner to that described above, thereby automatically controlling the temperature change in the shallow sea into which the wastewater is discharged to be as small as possible.

るように自動制御するのである。Next, in the embodiment shown in FIG. 3, the opening/closing control valves 9 and 12 in the embodiment shown in FIG. A water supply system is connected from the pump 11 system to the drainage system of the condenser 5 via an open/close control pulp 16. In this case, the temperature on the drainage side measured by the temperature sensor 13 is determined by the temperature sensor When the seawater temperature near the water intake T also rises, the temperature difference detector 15
The opening/closing control valve 16 is controlled once by the detected power, and seawater taken from the deep sea, which has a lower temperature, is mixed into the wastewater, and this mixing lowers the temperature of the wastewater, and the wastewater is also discharged. This system automatically controls temperature changes in the shallow sea to minimize them as much as possible.

発電効率を高め得るなどの利点も併有するものである。As described in detail above, according to the present invention, in a steam condensing device of a power generation facility that supplies water taken from the shallow sea and condenses it, a water intake system from the deep sea, which has a much lower temperature, is installed, and the condensing water is A detector is installed to detect the temperature difference between the temperature on the drainage side of the vessel and the temperature near the shallow water intake, and the detection power of this temperature difference detector is used to control the open/close control valves arranged in each water supply system. By supplying low-temperature water taken from the deep sea to a condenser, the temperature of the wastewater is relatively lowered, or by mixing it with the wastewater, which lowers the temperature of the wastewater. The temperature of the wastewater discharged into the shallow sea can be made as uniform as possible to the temperature of the seawater in this shallow sea, and therefore the environmental problems associated with the discharge of wastewater can be automatically resolved. In such cases, by supplying a large amount of low-temperature seawater to the condenser, the condensing performance can be increased, which secondarily improves the degree of vacuum inside the condenser.
It also has the advantage of increasing power generation efficiency.
