Is excessive, the adjusting valve CV4 on the inlet side of the storage tank 3 is opened to store the excessive amount, and when the water supply 16 from the heat exchanger 2 is insufficient, the makeup water pump 7 and adjusting valve on the outlet side are provided. Each CV5 is driven and opened to make up for the shortage. Furthermore, the hot water boiler 4 is driven when the amount of steam supplied to the process is insufficient even though the water 16 is supplied from the heat exchanger 2 and the storage tank 3. That is,
The water supply 16 from the water supply tank 5 mentioned above is pressurized by the water supply pump 6 and introduced through the adjusting valve CV6 to make the water supply 16 of the specified temperature, and the water supply 16 of the specified temperature is introduced into the heat exchanger 12 described above. I have to. Reference numeral 11 in the drawing denotes a prime mover for driving the compressor 10, which is rotated by electric power, and 13 denotes an expansion mechanism for reducing the pressure of the working medium 17 into wet gas.
次に、かかる如く構成した太陽熱利用蒸気発生システム

る。First, in the heat collecting system shown in FIG. 1, the heat medium 15 is supplied with the solar heat energy collected by the solar heat collector 1, and is controlled to a specified temperature by adjusting the heat medium pump 8 and the adjusting valve CV1. . In this case, in order to control the heat medium 15 to the specified temperature, the outlet temperature of the solar heat collector 1 is monitored, and the opening of the adjustment valve CV1 is adjusted based on the deviation signal between this and the specified temperature to adjust the flow rate. Restrictions are enforced. In this way, the heat medium 15 that has reached the specified temperature due to the heat collection by the solar heat collector 1 exchanges heat with the water supply 16 in the heat exchanger 2, and the water supply 16 stabilizes the water supply 16. Is heated.

４は停止状態にある。Next, in the water supply system, at the time of normal solar radiation (when the amount of solar radiation required for system operation is obtained), the water supply 16 is boosted from the water supply tank 5 by the water supply pump 6 and passes through the regulating valve CV2 for heat exchange. It is heated by the heat medium 15 on the side of the solar heat collector 1 in the container 2 to become the feed water 16 of the specified temperature. At this time, the regulating valve CV2 limits the flow rate of the feed water 16 so that the outlet temperature of the heat exchanger 2 becomes the specified temperature. In this operating state, the regulating valve CV6 is in the fully closed state, and the hot water boiler 4 is in the stopped state.

合には調整弁CV5は全閉状態にあり、補給水ポンプ７も
停止状態にある。Further, in this case, the amount of solar radiation that reaches the solar heat collector 1 varies depending on the state of the atmosphere in the solar thermal energy. That is, when the amount of solar radiation is high, the solar heat collector 1
Since the amount of heat that can be collected by the
When the circulation amount of 15 exceeds the specified value, the heat exchanger 2
The amount of the feed water 16 having a specified temperature heated by is also increased from the specified amount. Therefore, the adjustment valve CV
By the adjustment of 3, the specified amount required by the process is introduced into the heat exchanger 12, and the surplus hot feed water 16 is stored in the storage tank 3 through the adjustment valve CV4. In this case, the regulating valve CV5 is in the fully closed state, and the makeup water pump 7 is also in the stopped state.

開状態にあり、調整弁CV4は全閉状態にある。On the other hand, contrary to the above, when the amount of solar radiation is low, the amount of heat that can be collected by the solar heat collector 1 decreases below the specified value, so the circulation amount of the heat medium 15 becomes less than the specified value, and the heat medium in the heat exchanger 2 is reduced.
The amount of feed water 16 heated by 15 at the specified temperature also decreases below the specified amount. Therefore, in such a solar radiation state, by activating the makeup water pump 7 and adjusting the adjusting valve CV5, the water supply 16 in the storage tank 3 that has stored the excess water supply 16 when the amount of solar radiation is high, It will be introduced into the heat exchanger 12. In this state, the adjusting valve CV3 is fully open and the adjusting valve CV4 is fully closed.

2,CV3,CV4,CV5はそれぞれ全閉状態にある。Next, when there is no light (when the amount of solar radiation required for system operation cannot be obtained in bad weather or at night), there is no high-temperature water supply 16 from the heat exchanger 2, so the hot water boiler 4 is started. . That is, the water supply from the water supply tank 5 passes through the regulating valve CV6, and the hot water boiler 4 produces the water supply 16 at the specified temperature. At this time, the flow rate of the water supply 16 is controlled by the regulating valve CV6 so that the water flow 16 flows at a specified flow rate. In this non-illuminated state, the solar heat collector 1 is on standby in a state where sunlight is not collected, and the heat medium pump 7 that supplies the heat medium 15 is in a stopped state. In addition, each regulating valve CV of the water supply system
2, CV3, CV4, CV5 are all fully closed.

The heat exchange is performed, and the working water 17 heats the feed water 16. As a result, the feed water 16 is stably supplied to the process as usable steam of higher temperature and pressure, and is used for power generation and process heat by driving a turbine (not shown). The working fluid 17 of the saturated liquid, which has been heat-exchanged in the heat exchanger 12 as described above, passes through the expansion mechanism 13 and is reduced in pressure to become wet gas, and is supplied to the heat exchanger 9 again.

のでよいので、設備面積を縮小することができる。As described above, in the solar heat utilizing steam generation system according to the present embodiment, heat exchange is performed by the heat exchanger 12 as compared with the conventional single heat collection system using solar heat energy, so the facility cost of the solar heat collector 1 is increased. Can be reduced, and since the capacity of the solar heat collector 1 can be small, the equipment area can be reduced.

しかも信頼性の高いシステムとすることができる。In addition, a cycle of the working medium 17, called a heat pump cycle, allows the waste heat source 14 from the process to be effectively utilized. That is, the cycle of the working medium 17 uses the waste heat source 14 discharged from a factory or the like as a heat source, and the working medium 17 is converted into high-temperature, high-pressure energy that can be easily used by the compressor 10, thus saving energy. It is an economical system. Specifically, the prime mover 11
With respect to the input of 1 kW, the output that transfers heat to the water supply 16 in the heat exchanger 12 is 3 W, which is an economical cycle about 3 times. From the above, this solar heat utilization steam generation system is extremely economical,
Moreover, the system can be made highly reliable.
又、貯蔵タンク３が設けられているので、日射量の高い

以下となった場合、貯蔵タンク３の給水を熱交換器12に
供給できる。Since the storage tank 3 is provided, the surplus water supply 16 can be stored when the amount of solar radiation is high, and the amount of heat that can be collected by the solar heat collector 1 is less than the specified value because the amount of solar radiation is low. When it becomes low, the water supply of the storage tank 3 can be supplied to the heat exchanger 12.

Therefore, the amount of steam supplied to the process can be stably supplied.
