When the diesel engine 1 is operated and exhaust gas is supplied to the steam generator 4, the controller 10 detects the temperature and flow rate of the supplied exhaust gas and controls the pump 11 to match the supplied amount of exhaust gas.

The plate is heated and sprayed in the form of a mist by exhaust gas at about 450°C to generate a printing plate. This steam drives a turbine 5, and is then condensed in a condenser 8 and stored in a water tank 9. Note that the exhaust gas contains harmful substances such as NOx, but these are absorbed into water in the steam generator 4 and water tank 9 and removed as appropriate through the treatment equipment 12 and 13. What remains as a gas without being absorbed by the water is drawn out using a vacuum pump 7 connected to a condenser 8 and removed through a processing device 14. The water stored in the water tank 9 is pumped again to the steam generator 4 by the pump 11.

o has a critical temperature of 35° C. and 70 kg/−, and is stable without thermal decomposition even when the temperature and pressure are increased to 65′ C and 130 kg/c1a. Therefore, it has already been considered to take advantage of the critical temperature of 35°C, 70kg/cJ and the stable properties of COl to raise the temperature and pressure of COt to 65°C and 1130kg/cJ and use it for turbine power generation. It has been proposed that it can be applied to heat sources. When the exhaust gas contains a large amount of CO2, the above-mentioned properties of CO2 will work effectively. That is, the steam generator 4
If a large amount of exhaust gas is supplied to the turbine 5 together with the steam generated, CO2 will be supplied at a temperature exceeding the critical temperature.

所定の値に維持することも必要である。In FIG. 2, refrigerants 23 and 24 are lithium bromide dihydrate (Li-Br・2+1□0) mixed with an alcoholic liquid such as ethanol or methanol. The condensation tank 22 was housed under a vacuum of about 75 mm of mercury, and the condensation tank 22 was housed under a vacuum of about 71 mm of mercury. Then, steam or hot water from the steam generator 4 shown in FIG. 1 is supplied into the refrigerant 23 housed in the evaporation tank 21, and the refrigerant 23 is heated under a vacuum of about 75 mm of mercury. Since the refrigerant 23 contains an alcohol-based liquid, its boiling point is low and even steam or hot water at about 65° C. will boil and evaporate. Further, above the surface of the refrigerant 23 of the evaporation tank 21, a pipe through which water from the outdoor cooler flows is arranged, and a saucer 26 is arranged below the pipe, so that the refrigerant 23
The water vapor that has boiled and evaporated is turned into wet steam here and sent to saucer 2.
6 to the condensing tank 22, and during the flow, cold water is generated by adiabatic expansion. This cold water is condensed in the tank 22.
Here, the cooling water pipe is cooled and joined with the refrigerant 24. As a result, the water flowing back through the cooling water pipe is cooled from 12°C to about 7°C. In this process, the concentration of the refrigerant 23 increases due to boiling and evaporation, and conversely, the concentration of the refrigerant 24 decreases due to the joining of cold water. It is also necessary to circulate a part of the refrigerant 24 back to the refrigerant 23 in the stem tank 21 using the refrigerant to maintain the concentration of the refrigerant at a predetermined value at all times.

２では、蒸発タンク２１から高温で還流する冷媒のため

ように冷媒２４の温度を下げるものである。As mentioned above, in refrigeration equipment, lithium bromide dihydrate, whose boiling point has been further lowered by mixing an alcoholic liquid, is used as a refrigerant, and the water is evaporated and condensed in the evaporation tank 21, and during the process, it is converted into cold water by adiabatic expansion. The system generates water that flows through air-conditioning water pipes to cool the water. This makes it possible to effectively utilize low-temperature heat sources that were generally considered difficult to utilize. In FIG. 2, the cooling water heated to 32°C gfN'/Nr by the outdoor cooler is for supplementary cooling of the water vapor in the evaporation tank 21 and the refrigerant 24 in the a-condensation tank 22. and to improve the condition of the condensation tank 22. That is, in the evaporation tank 21, a part of the water vapor is cooled and condensed to become wet steam, thereby increasing the effect of adiabatic expansion, and the condensation tank 2
In step 2, the temperature of the refrigerant 24 is lowered so that the discharge temperature of the water recirculating through the cooling water pipe does not rise due to the refrigerant recirculating at high temperature from the evaporation tank 21.

ることが可能となる。- In the case of refrigeration equipment that uses a heat source, for example, fresh water at 90°C is replaced with boiling water at 95°C, and this is used as a heat source to heat the water to 5°C or more.
It produces cold water of about 10°C. Therefore, in this refrigeration equipment, even if there is a low-temperature heat source, it cannot be utilized if the temperature is below the above-mentioned temperature, and a low-temperature heat source below 80°C has a coefficient of performance of only about 3 to 4 at best. However, as mentioned above, if lithium bromide dihydrate (Li-Br・2+1□0) mixed with an alcoholic liquid is used as a refrigerant, the temperature will be as low as 65℃ to 68℃. Refrigerators can also be operated using hot water as an energy source. Moreover, as a result, the coefficient of performance can be doubled from 3 to 4 to 7 to 8. This makes it possible to utilize the thermal energy of low-temperature geothermal fluids more widely.

て利用してもよいことはいうまでもない。Note that the present invention can be modified in various ways and is not limited to the above embodiments. For example, as a heat source, it is of course possible to use not only industrial waste gas but also exhaust gas from a garbage incinerator or other heat engine. It goes without saying that a hot water generator may be used in place of the steam generator and used as a heat source for power other than a turbine generator or for heating and cooling using an absorption refrigerator.

るため、無駄なく蒸気及び温水をつくることができる。As is clear from the above description, according to the present invention, it is possible to use hot waste gas to generate turbine power generation using gas and steam, and to utilize hot water (for air conditioning, heating, hot water, etc.). Furthermore, since steam and hot water are directly generated by spraying water onto hot waste gas, steam and hot water can be produced without waste.

システムの簡素化を図ることができる。Because of this high heat exchange efficiency, it is possible to recover down to temperatures as low as 120'C, which was conventionally said to be around 200°C. This system also eliminates the need for a waste heat boiler (heat exchanger) to generate steam and hot water.
The system can be simplified.
