The first regenerator 7 having the condensing tube group 4 is arranged at a higher position than the waste heat recovery section.

Here, heat is released and condensed, and this condensed liquid descends through the liquid communication pipe 5 and returns to the evaporation tube group 2. That is, the heat transfer medium on the waste heat recovery section side naturally circulates in this closed circuit due to the difference in specific gravity caused by the phase change between vapor and liquid (water). Therefore, there is no need to install a forced circulation device such as a pump in the circulation system. Furthermore, since it is a closed circuit, a make-up water supply system is basically unnecessary, but even if it is necessary, a water supply system of extremely high walking capacity is sufficient.

A refrigeration cycle is constructed by circulating fluid through a condenser (hereinafter simply referred to as "second regenerator") 8, a steam absorber 9, a pump 10.13, and a heat exchanger 11.12. Reference numeral 14 is a cooling water passage, through which cooled water is discharged from the system through an outlet 15 and used. Similarly, water introduced from the inlet 16 is cooled and discharged to the outside via the outlet 17. In this case, the thermal demand on the cooling water user side is detected as the cooling water temperature at the cooling water outlet 17, and the control device 18 controls the circulating flow rate of the heat transfer medium on the waste heat recovery section side, and is operated by this device. The temperature is adjusted by adjusting the opening degree of the flow rate control valve 6, and the amount of heat corresponding to this temperature is controlled to be supplied to the cooling system side. Note that in the above configuration, the heat exchanger tube group of the waste heat recovery section may be a heat pipe.

That is, in the heat exchanger 21 of the cooling system, a high amount of heat on the exhaust gas side can be supplied to the cooling medium solution returning to the first regenerator 7, thereby making it possible to further increase the efficiency of the cooling system.

ルである。In this embodiment, a denitrification device is disposed in the waste heat recovery section to transport heat to the cooling system and to adjust the temperature of the exhaust gas in the flue to a temperature suitable for the denitrification reaction. That is, the denitrification device 23 is arranged in the evaporator tube group 2, and the flow rate N is adjusted so as to adjust the flow rate of the heat transfer medium in at least the evaporator tube group 2a located directly upstream of the denitrification device 23 in the evaporator tube group 2. A control valve 25 is provided, and the opening degree of the valve 25 is adjusted by an operating signal from an exhaust gas temperature controller 26 located immediately before the denitrification device 23. By adjusting the flow rate per unit time of the heat transfer medium passing through the evaporator tube group 2a, the amount of heat absorbed by the evaporator tube group 2a is adjusted, thereby controlling the temperature of the exhaust gas passing through the denitrification device 23. Adjust the temperature to the appropriate temperature. Reference numeral 24 is a nozzle for injecting a denitration agent such as ammonia.

As in the example, a denitrification device may be arranged for a group of condensing tubes constituting one closed circuit.

That is, in addition to the heat transfer tube group in the exhaust gas flow to the first evaporator tube group 2 and the second evaporator tube group 19, the third evaporator tube group 51 is further downstream of the second evaporator tube group 19. Deploy.

Thereby, the heat of the exhaust gas on the downstream side of the second evaporator tube group 19 can be used more effectively. Note that the cooling medium vapor discharged from the first regenerator 7 passes through the medium communication pipe 55 and is transferred to the cooling medium in the second regenerator 8 in the heat transfer tube group 56 in the second regenerator 8, thereby improving thermal efficiency. We are striving for further improvement. Note that the heat transfer medium circulating in the closed circuit including the second evaporator tube group 19 transfers heat to the cooling medium returned to the first regenerator 7 in the heat exchanger 11 . Further, reference numeral 57 is a heat exchanger that exchanges heat between the cooling medium headed for the second regenerator 8 and the coolant headed for the first regenerator 7. Note that the exhaust gas temperature in each evaporator tube group has, for example, the following values. That is, if the temperature is approximately 220° C. downstream of the first evaporator tube group 2, the temperature is approximately 170° C. downstream of the second evaporator tube group 19, and approximately 120° C. downstream of the third evaporator tube group 51.

る。Diagram A shows the cooling output of a so-called single-effect type device consisting of one evaporator tube group and one regenerator.While this type of device can operate even at a relatively low exhaust gas temperature, the The cooling output is low and the thermal efficiency is not very high. Diagram B is the first regenerator (low temperature regenerator) as shown in Figure 5.
7 and a second regenerator (high temperature regenerator) 8, the cooling output when only the second regenerator 8 is used is shown. In this case, when the exhaust gas temperature becomes high, the cooling output increases rapidly, but the cooling output is generally lower than the single-effect type, and the thermal efficiency is not good. On the other hand, the diagram shows the case where a heat exchanger 11.57 is used in addition to the second regenerator 8 in the configuration shown in Fig. 5, which greatly improves the cooling output and achieves high thermal efficiency. It can be seen that this has been achieved. Furthermore, diagram C shows the case where the first regenerator 7 is also used in addition to the second regenerator 8 and the heat exchanger 11.57, and in this case, the highest cooling output can be obtained, and the device with the configuration shown in the diagram It can be seen that the thermal efficiency is high.

。As described above in detail, the present invention provides a closed circuit by connecting a group of heat transfer tubes on the heat supply source side and a group of heat transfer tubes (condensing tubes) in a regenerator of a cooling system with a connecting tube. A heat transfer medium such as water is sealed in this closed circuit, and due to the phase change of the heat transfer medium, it is possible to circulate the medium using a natural circulation method by utilizing the difference in specific gravity between gas and liquid. Therefore, devices such as forced circulation pumps, water tanks, water replenishment pipes, water replenishment pumps, and deaerators are not required, making it possible to simplify the entire device and reduce the cost.
