BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to rotate a turbine from a fluid in a low-to-medium temperature range, which is generally discarded, by heat replacement, and replace it with another energy by power generation or the like, thereby causing environmental damage such as hot drainage. It aims to provide an inexpensive and efficient device that eliminates energy waste.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional side view of the negative part of the apparatus shown in FIG.
Shows a partially cutaway plan view thereof, FIG. 3 shows a low boiling point methylene chloride vapor pressure table, and FIG. 4 shows a partially broken side view of another example.

As shown in FIG. 1, the present apparatus has a structure in which a case portion is composed of a pressure resistant sealed container 1 for evaporation and a pressure resistant sealed container 2 for cooling, and a container partition plate 13 partitions the space between them. .

Below the evaporation pressure-proof sealed container 1, a suitable amount of the low boiling point solvent 26 is a warming liquid flowing from the outside of the container,
The heat exchange pipe 25 provided inside is immersed from the heating liquid inlet 27 and discharged from the heating liquid outlet 28.

Therefore, the low boiling point solvent 26 evaporates and is heated in the upper part by the heat exchange melting pipe 25 to become supersaturated vapor, and the opening / closing valve 5 fixed to the container partition plate 13 in the upper part and its outlet. The spray nozzle 4 rotates well with the impeller 6 installed outside the impeller storage case 18 provided in the container partition 13 on the inner side of the pressure-resistant sealed container 2 for cooling next to the spray nozzle 4 mounted on the side. Since the output shaft is output to the outside via the impeller shaft 12 which is the central shaft of the impeller 6, the shaft and the generator 7 are connected to generate electric power.

The impeller 6 extending outside the impeller storage case 18 is inside the pressure-resistant closed container 2 for cooling, and this part has a radiator 10 for cooling inside. A cooling pipe having a length of several meters is laid inside by the cooling water inlet 9 from the outside, and finally becomes a hot water or a hot solvent while liquefying the steam filled inside, and the hot water outlet 21 More discharged to the outside.

For this reason, the inside of the container is brought into a state close to vacuum due to the liquefaction of the vapor, and the impeller 6 is provided with the spray nozzle 4
Due to this, high-speed rotation can be performed in a place where the steam squeezed to a high pressure is radiated into the container near the vacuum.

A liquid level sensor 11 is provided at the bottom of the cooling pressure-tight sealed container 2, a high-pressure pump 22 having an inlet for the liquefied solvent at the bottom, and a backflow prevention solenoid valve 23 in the middle. A discharge side of the pump is fixedly attached to the bottom of the pressure-resistant sealed container for evaporation 1 so that the solvent can freely flow therein.

The container is divided into an upper part and a lower part, the upper container joining part 14 and the lower container joining part 17 together with the inner container partitioning plate 13 and the packing 15 so that the container can be divided into upper and lower parts. It is structured so that it can be secured by tightening with bolts when it is sandwiched.

Therefore, the low boiling point solvent 26 has physical properties which are less dangerous even if it becomes a high pressure supersaturated vapor, and is 30 ° C.
Since a solvent having a boiling point of about 40 to 40 ° C. is suitable, in the present invention, it is assumed that a CFC system or methylene chloride system is used as a solvent compatible with this, and the temperature of the methylene chloride in the closed container is shown in FIG. The following table shows the relationship between the vapor pressure and the vapor pressure.

According to this table, it is common waste hot water 4
In the situation of 0 ° C. to 95 ° C., the pressure becomes 1 to 6 atm, and the pressure difference becomes available.

FIG. 4 shows an inverse use of the previously described apparatus, with the inverse U
Both ends of the pressure resistant tube are a pressure resistant sealed container 1 for evaporation and a pressure resistant sealed container 2 for cooling, respectively.
Is rotated as a supersaturated vapor by rotating an impeller 6 with an on-off valve 5 and a spraying nozzle 4 provided in the middle, power is generated by a generator 7, and a liquefied solvent is evacuated by a high pressure pump 22 via a backflow prevention solenoid 23 to a pressure-proof sealed container for evaporation Return to 1.

With such a structure, the heating liquid inlet 27
By circulating more warm liquid and circulating cold water or a cooling solvent together from the cooling water inlet 9, supersaturated steam is generated by the opening / closing amount of the internal opening / closing valve 5 of the evaporative pressure resistant sealed container 1 and sprayed. High pressure is injected from the nozzle 4 to the impeller 6, which is rotated and the generator 7 is operated to generate electricity.

In the pressure-proof cooling container 2 for cooling, cooling by the cooling radiator 10 measures the liquefaction and decompression of the steam, and by using the cooling water as hot water, hot water of about 40 ° C. is produced. Use as hot water supply.

The liquefied solvent is returned to the pressure-resistant sealed container 1 for evaporation again by the high-pressure pump 22 and recycled, so that the solvent is not discharged to the outside at all, and the structure is safe. It has a shape.

As described above, it is possible to generate electric power with the low-temperature hot liquid, and when the hot water or the hot liquid is repeatedly sent from the storage tank by the pump, the stored heat energy can be converted into electric energy as needed. Also, it is a fully sealed closed low temperature heating turbine that can be reused as hot water supply by completely warming the water generated by cooling and the solvent used can be completely recycled.

[0022]

As described above, the constitution of the present invention is advantageous in that power can be generated by using a low boiling point solvent with a low temperature hot liquid, and the solvent used can be completely recycled by cooling and liquefying it. It is possible to provide a closed low-temperature heating turbine which is the above device.
