By converting the rotational energy into electrical energy and generating electric power, and cooling the working medium that has reached a high temperature with the heat sink of the cooling box 2, the vaporizer 27 of the cooling device, and the heat sink 9. The present invention relates to a circulating solar power generation apparatus in which a medium circulates in the circulating solar power generation apparatus and generates power.

Conventionally, as a method of generating electric power using an updraft, there is a solar up draft tower type electric power generation device shown in FIG.

In FIG. 17, the solar updraft tower includes a collector section 40, a chimney section 41, and a wind power generator 42. The collector part 40 is composed of a greenhouse-like facility whose ground is covered with a canopy such as glass or transparent plastic, accumulates solar thermal energy in the collector part 40 to warm the air, and the chimney part 41 is warm air generated in the collector part 40 Is generated to generate an ascending air current, and the wind power generator 42 installed on the ground is driven by the air current rising inside the collector 40 and the chimney 41 to generate electric power.

US Patent US 4,275,309 June 23, 1981

However, since the wind power generator 42 of the solar updraft tower type power generator is installed on the ground, in order to obtain the energy for rotating the wind power generator 42, a large amount of kinetic energy of the updraft is required, and Since the wind power generator 42 is installed on the ground, the energy of the updraft generated on the ground cannot be used 100%, and only a few tens of percent can be used.
Also, when the height of the chimney is low, the difference between the outside air temperature at the top of the chimney and the temperature inside the chimney is small, so the kinetic energy of the updraft in the chimney is small, so a large amount of power generation cannot be obtained was there.
Further, when the site area of the collector section 40 is small, the amount of generated ascending airflow generated in the collector section 40 is small, so that the energy for driving the wind power generator 42 is small, and there is a disadvantage that the power generation amount is small.

Therefore, in order to increase the difference between the outside air temperature at the top of the chimney and the temperature inside the chimney and obtain a great amount of kinetic energy of the updraft, the chimney must have a height of several hundred meters or more. there were.
Further, since the wind power generator 42 is installed on the ground and in the collector unit 40 and an upward air flow is always generated, as a countermeasure at the time of maintenance of the wind power generator 42, an apparatus for preventing the upward air flow is provided. There was a drawback that a great deal of cost was incurred.

Moreover, the site area of the collector part 40 for obtaining the rotational energy of the wind power generator 42 installed on the ground needs a huge site area and must be flat. If it is not flat, there is a drawback that the airflow is retained and the energy of the rising airflow cannot be obtained sufficiently.

Therefore, because of the high chimney and the collector section 40 on the vast site, it is vulnerable to natural disasters, especially earthquakes, storms, etc., and cannot be installed in places with short sunshine hours.

The present invention solves the above-described conventional problems, and can produce a large amount of power generation without a chimney of several hundred meters, is resistant to natural disasters, and generates power regardless of day and night, fine rain, and sunshine hours. It is an object of the present invention to provide a power generation apparatus that can be reduced in size and cost.

In order to solve the above-described problems, in the present invention, a downdraft is generated by generating an updraft simultaneously with an updraft generated by solar heat, the working medium circulates in the apparatus, and a cooling device other than solar heat Ascending current is generated by the heat generated by the condenser 22 and the auxiliary condenser 25 and the heat generated by the heater 50 to obtain the energy of the rising air.

In addition, in order for the working medium to circulate in the circulating solar power generator and generate electric power, a heat storage box 1 that generates an updraft, a rotary tube 3 that converts the energy of the updraft into rotational energy, and the rotational energy into electricity A generator 4 that converts energy, a radiator plate that constitutes a cooling box that radiates the heat of the hot working medium to the outside of the circulating solar power generator, a plurality of radiator tubes 9, and a vaporizer that cools the working medium itself The cooling box 2 with the built-in air and the cooled working medium is a downflow, and is constituted by a blower box 5 that blows air to the heat storage box 1.

Further, in the present invention, an updraft is generated in the heat storage box 1 and at the same time a downflow is generated in the blower box 5 due to the upflow, and the working medium is sucked from the cooling box 2, the rotary tube 3 and the heat storage box 1. The working medium circulates with the heat storage box 1, the rotary tube 3, the cooling box 2, the blower box 5, and the heat storage box 1.

Moreover, in this invention, in order to convert the kinetic energy of an updraft into 100% rotational energy, the rotary tube 3 is provided in the ceiling of the heat storage box 1, and the rotary tube 3 is provided with the cooling vent 11 on the cooling box 2 side. In order to make the speed of the ascending airflow flowing into the rotary tube 3 larger than the ascending speed at the lower part of the heat storage box 1, the heat storage box 1 is narrowed from an arbitrary height toward the ceiling. It is characterized by that.

Further, the volume of the rotary tube 3 is made smaller than the volume of the heat storage box 1 in order to make the temperature and pressure in the rotary tube 3 higher than the pressure and temperature in the heat storage box 1 and the temperature and pressure in the cooling box 2. Thus, adiabatic compression is generated in the rotary tube 3 by the kinetic energy of the rising airflow of the heat storage box 1.

In order to make the speed of the working medium ejected from the plurality of L-shaped nozzles 31 larger than the inflow speed of the working medium flowing into the rotary tube 3, the total cross-sectional area of the plurality of L-shaped nozzles 31 ejection openings Is smaller than the cross-sectional area of the rotary tube 3.

Therefore, the working medium ejected from the plurality of L-shaped nozzles 31 is cooled by the difference between the temperature of the cooling box 2 and the temperature of the rotary tube 3 and the difference between the pressure of the cooling box 2 and the pressure of the rotary tube 3. The heat of the working medium is radiated from the adiabatic expansion in the box 2 to reduce the temperature of the working medium itself.

In the present invention, the high-temperature working medium flowing into the cooling box 2 is adiabatically expanded to dissipate the heat of the working medium to the cooling box 2 and to dissipate the dissipated heat to the outside of the circulating solar power generator. The air outside the solar thermal power generation apparatus is blown to the heat radiating pipe 9 by the blower 10, and the heat radiating pipe 9 is provided to absorb the heat from the outside air flowing into the heat radiating pipe 9 and release it outside the circulation type solar thermal power generation apparatus. Features.

It is provided in the power generator.

In addition, an auxiliary electric motor 23, an auxiliary compressor 24, and an auxiliary condenser 25 are provided to assist carrying out the refrigerant liquefied by the condenser 22 to the capillary tube 26 provided at a height of several meters or more from the condenser 22. Characterized by

Moreover, in this invention, the heat | fever which generate | occur | produces with the condenser 22 and the auxiliary condenser 25 of a cooling device is thermally radiated to the thermal storage box 1, and an updraft is generated, It is characterized by the above-mentioned.

Also, by providing the cooling tube 2 with the capillary tube 26 and the vaporizer 27 in the cooling box 2, when the liquefied refrigerant is vaporized in the vaporizer 27, the heat in the cooling box 2 is absorbed and the cooling box 2 The working medium is cooled at the same time as the temperature of the liquid is lowered.

Moreover, in this invention, the some heater 50 was provided in the thermal storage box 1, the temperature detector 51 was provided in the ceiling of the thermal storage box 1, and the control apparatus 52 was provided outside the circulation type solar thermal apparatus.

Further, the temperature of the ceiling of the heat storage box 1 is measured, and when the temperature measured by the temperature detector 51 is below the set range, the power of the heater 50 is turned on by the control device 52, and when the temperature is above the set range, the heater 50 is turned off by the control device 52, and the temperature of the rising airflow in the heat storage box 1 is always kept within the set range, thereby obtaining the power generation amount within the set range.

As described above, the circulating solar power generation device is characterized in that it can generate power regardless of the outside air temperature, day and night, season, and fine rain.

The heat generated by the solar heat / cooling device condenser 22 and auxiliary condenser 25 and the heat generated by the heater 50 generate an updraft and downdraft in the circulating solar power generator, and rotate the kinetic energy of the updraft and downdraft. By generating electricity by converting it into energy or electric energy, it is possible to constantly obtain a power generation amount within a set range regardless of day and night, fine rain, season, and outside temperature.

Further, since the fossil fuel is not burned, the fuel cost can be reduced to zero without generating carbon dioxide gas, so that the power generation cost can be greatly reduced.

Moreover, since the electricity used with the electric motor 20, the auxiliary electric motor 23, and the heater 50 can use the electric power generated with the circulation type solar thermal power generation apparatus, the electricity is not supplied from the outside.
Therefore, the circulation type solar thermal power generation apparatus does not cost other than initial investment and maintenance costs.

Since the circulating solar power generator uses the updraft and descending airflow to produce the power generator, it does not require a large site and a high chimney, so construction costs can be reduced, and the circulating solar power generator The device can be miniaturized.
