ている。As a solution heating concentrator of this type, the present inventors have previously developed a solution heating concentrator and filed an application in Japanese Patent Application No. 151763/1983. FIG. 4 is a diagram showing the system configuration of the solution heating concentrator. In the figure, 1 is a heat pump main body, and the heat pump main body 1 is connected to a heating tower 2 through a brine heat collection path 3. Also,
A solution heating concentrator 4 is connected to the brine heat collection path 3 .

を有している。The solution heating and concentrating device 4 includes a regenerator 5, a condenser 6, a heat exchanger 7, and a dilute solution path 8. The regenerator 5 and the condenser 6 are in communication with each other, and the concentrated solution outlet of the regenerator 5 is The condenser 6 is connected to a heat exchanger 7 through a concentrated solution path 9, and the condenser 6 is connected to a condensate outlet 10.
have.
ブラインの濃縮は、溶液加熱濃縮装置４の再生器５で希
溶液を加熱し、濃縮しており、ブラインの希釈は水道水
をヒーティングタワー２に供給することにより行なって
いる。The brine is concentrated by heating and concentrating a dilute solution in the regenerator 5 of the solution heating and concentrating device 4, and the brine is diluted by supplying tap water to the heating tower 2.
上記構成の溶液加熱濃縮装置によれば、低熱源が利用で
き且つ熱回収ができるので非常に有用な装置である。According to the solution heating concentrator having the above configuration, a low heat source can be used and heat can be recovered, so it is a very useful device.
〔発明が解決しようとする問題点〕
しかしながら上記構成の溶液加熱濃縮装置は、ブライン
が希釈し、濃縮を必要とする場合は、濃縮装置として有
効に作用するが、他の場合は熱源の利用価値がなく無為
に捨てられていた。[Problems to be Solved by the Invention] However, the solution heating concentrator with the above configuration works effectively as a concentrator when the brine is diluted and requires concentration, but in other cases the heat source has no utility value. It had been thrown away for nothing.
この熱回収方法としては、図示するように熱回収用の熱
交換器ＨＣを設置して、ブラインと熱交換をさせるのが
一般的で簡便な方法であるが、特別の熱交換器を必要と
し、加熱源が水でブラインが低温の時は凍結防止が必要
であり、複雑で且つ高価となるという欠点があった。As for this heat recovery method, a common and simple method is to install a heat exchanger HC for heat recovery and exchange heat with brine as shown in the figure, but it does not require a special heat exchanger. However, when the heating source is water and the brine is at a low temperature, anti-freezing is required, which is complicated and expensive.

点があった。In addition, it is easy to supply tap water to dilute the brine when it is completely concentrated, but there is a problem in that the impurities contained in the tap water accumulate in the brine and contaminate the brine. When using pure water, a separate pure water production device must be prepared, which is expensive.

てもよく、外部加熱源経路１３に排出してもよい。In this state, the diluted prine is diverted from the brine heat collection path 3 on the exit side of the heating tower 2 and is caused to flow into the condenser 6 by the pump P. Since this diluted brine is at a low temperature, while passing through the condenser 6 as a cooling heat medium, the diluted brine condenses water vapor that evaporates in the regenerator 5 and flows into the condenser 6, and recovers heat. The level increases. The internal pressure of the regenerator 5 decreases due to the condensation of this water vapor. After passing through the condenser 6 , the dilute solution path 8 is heated in a heat exchanger 7 and flows into the regenerator 5 . In the regenerator 5, external heating source path 1
The dilute brine is heated and concentrated by passing the heating medium through the dilute brine. At this time, as mentioned above, the internal pressure of the regenerator 5 is low, so the water absorbed in the dilute brine at a low boiling point is separated as water vapor. Ru. The concentrated brine from which water has been removed returns to the brine heat collection path 3 while heating the diluted brine in the heat exchanger 7 on the way as described above. Furthermore, the condensed water condensed in the condenser 6 may be discharged to the outside of the solution heating concentrator 4 or to the external heating source path 13.

By introducing the heating medium from the heat source through the heating source and heating the brine, the water contained in the brine evaporates and is condensed in the condenser 6. At the same time, the water is diverted from the brine heat collection path 3 by the pump Pl to the condenser. Heat is transferred to the brine flowing into 6 to condense it. The condensed water flows through the switching valve V and the path 12.

By simply doing this, it is possible to provide a solution heating concentrator at a low cost that has a stable concentration function, heat recovery function, and distilled water production function without adding any equipment.
