2. Description of the Related Art In recent years, the problem of energy and the environment has been taken up as the greatest problem for humankind. Regarding energy issues, fossil fuels used for thermal power generation, fuel cells, etc., have a question of permanence due to resource depletion and environmental issues.

[0003] The use of nuclear power is limited in location due to the problem of radioactive pollutants, and it is difficult to greatly expand it. There is no technical prospect for using fusion energy.

[0004] Other energies include the use of energy such as, for example, hydraulic, solar, wind, wave, or geothermal. These are advantageous in that they are clean and can be dispersed.
Low energy density or localized heat source.

It has already been proved by natural phenomena that clean effective energy can be created by connecting the evaporation and liquefaction cycles of the heat medium.

That is, there are typhoons, low pressures, tornadoes, etc., which release enormous energy, and the output energy is immeasurable. A typhoon is a huge heat engine that uses water and air as heat medium = heat pump / clean energy generation system. Volcanic phreatic explosions have also proven that huge exergy can be extracted from thermal energy.

The radiant energy of the sun that falls on the earth for one hour is said to be comparable to the energy consumed by all human beings for one year, but the earth, seawater, open air, river water, etc., store most of the solar radiant energy. It is a storage of heat energy.

[0008] If the latent heat can be exploited through the vaporization and liquefaction cycle by applying the heat energy provided to these to the heat medium, the energy generation system will be so enormous that the energy problem for humanity can be solved.

A system for realizing such a principle is as follows.
Known as a heat pump, thermal air conditioners, heaters,
It is commercialized as a hot water storage device. It is also considered to be used as a district heating or snow melting device by being connected to a heat collecting device.

It has been found that these heat pump systems can generate 3-8 times the heat energy supplied to operate the heat medium liquefaction compressor. However, there has conventionally been only utilization as heat energy.

The step (1) and the step (2) of heating the substance to be heated by pressurizing the vaporized heat medium through a heat exchanger other than the heat exchanger under pressure to liquefy the heat radiation are connected and circulated. Extract the volume expansion energy at the time of vaporizing the liquid heat medium and the heat radiation energy of the step (2),
It has been found that there is a material heat energy recycling system characterized by recycling as effective thermal energy and electric energy or kinetic energy. Patent applications have already been filed (Japanese Patent Application Nos. 11-338320, 11-338320). 375
962, Japanese Patent Application 2000-35840, Japanese Patent Application 2000-4
03545).

According to the present invention, heat, pressure, and volume change in the adiabatic state change of the gas-liquid heat medium or the state change due to transfer of heat from outside the system are extracted as effective work energy (exergy). The present invention relates to an invention which has been achieved as a result of studying an improvement method.

That is, according to the present invention, a heat medium comprising a gas and / or a liquid having a predetermined temperature (To) and a pressure (Po) is provided.
In a thermo-hydraulic power conversion system that expands or contracts while transferring heat from outside the system in an adiabatic state or outside the system, and the resulting changes in volume and pressure can be taken out as kinetic or electric energy (exergy), Is substantially airtight and slidable between an outer cylinder having a heat medium introduction portion and a discharge portion, and an inner cylinder attached to an inner flange capable of taking out a revolving shaft at both ends or one end thereof and the two cylinders. It is composed of a movable spiral continuous partition interposed in a possible state.The inner cylinder contacts the inner wall of the outer cylinder and rotates around the planet while rotating. The space is made to change continuously, the heat medium is taken in from the inlet at one end of the cylinder and discharged to the other end By Rukoto, the new thermal hydraulic power conversion system characterized by taking out the positive or negative exergy from the revolution axis and the first aspect. A second aspect of the novel thermo-hydraulic power conversion system is characterized in that a heat exchange function is provided outside the external cylinder so that heat energy can be transferred to and from the outside of the system. And Next, in these new thermo-hydraulic power conversion systems, a helical groove of a designed pitch is formed on the inner wall of the outer cylinder or the outer wall of the inner cylinder, and the helical partition slides in accordance with the revolution of the inner cylinder, A new thermo-hydraulic power system that is installed in a form that allows access and that the space formed by the partition walls and the inner and outer cylinders layered in the longitudinal direction of the cylinder is substantially airtight and continuously changes. A third aspect of the present invention relates to a conversion device. Further, in the above system and apparatus, as the helical sliding partition, as a slidable material, an organic polymer resin, a fluorine-containing resin, a carbon fiber resin composite material, a flat strip material selected from metals softer than the cylinder, A fourth gist of the present invention is a novel thermo-hydraulic power conversion device characterized by using various cross-section rods or a tube-like material containing gas.

The basic system of the present invention has a predetermined temperature (T
o) A heat medium consisting of a gas and / or a liquid having a pressure (Po) is expanded or contracted while transferring heat from outside the system in an adiabatic state or outside the system. It is a thermo-hydraulic power conversion system that can extract energy (exergy). Conventionally known systems include 1) a piston / cylinder, 2) a turbine with rotating blades, and 3) an eccentric rotor pump with vanes. There is.

The piston / cylinder is of a batch type, and the effective energy conversion rate of expansion work due to frictional energy loss, noise due to reciprocating motion, and conversion loss to rotational motion is low. Rotary bladed turbines are often used in steam power generation and gas turbines, but convert heat and pressure energy of a heat medium into fluid kinetic energy, and give the rotating blades a reaction or lift to convert them into rotational kinetic energy. Therefore, in a heating medium system having a small pressure difference and a small pressure difference, the effective work efficiency is extremely low. In the eccentric rotor pump with vanes, the operating loss of the vanes is large, and there is a problem of noise due to intermittent operation.

[0015] The novel thermo-hydraulic power conversion system of the present invention comprises:
Heavy-cylinder self-revolving spiral partition type thermal-to-pressure power conversion system, no valve is required like an eccentric rotor, rotation is smooth and noise is small, and pressure is not interposed by the kinetic energy of the heating medium like a turbine. Since the difference and volume expansion can be directly converted to rotary work, the effective work conversion efficiency of expansion energy can be close to 100% except for friction loss.

The installation of the spiral septum can be achieved by inserting a groove in the inner cylinder or the outer cylinder. The profile such as the pitch can be designed, and a volume expansion process, a constant volume process, and a volume reduction process can be appropriately set. One or more spiral partitions can be attached. In particular,
In the system of the present invention provided with an external heat exchange capability, the ability to design a profile is extremely advantageous in terms of improving work efficiency.

The cylinder material is steel, aluminum, titanium,
A metal such as magnesium is preferable, but a composite material such as CFRP or a reinforced thermoplastic resin can also be used depending on the heat medium. Further, the profile of the cylinder can be varied from a cylinder to a conical cylinder or a disk.

As the material of the spiral partition wall, in addition to metals such as aluminum and copper, a fluorine resin, a reinforced plastic polymer resin, and the like can be used. The shape is preferably a flat band shape, but it is also possible to use resin elastomers of various cross sections and these tubes.

In particular, in a large-capacity system, it is advantageous to use a tube to which gas pressure can be applied as the spiral partition wall material. In this case, the partition contacts between the inner cylinder and the outer cylinder and resiliently returns to its original shape as in the case of the ground contact state of the tires of automobiles and bicycles, so that friction between the cylinder and the partition at the groove wall does not occur. A heat medium expansion chamber can be formed.

The heat medium is defined by the system in which the system of the present invention is used. If the heat source temperature is selected, carbon dioxide gas, water, ammonia, a mixed water / ammonia system, hydrocarbon gas, chlorofluorocarbon gas, etc. Needless to say, can be used.

In the present invention, an application system of the heat-pressure power conversion system is a heat medium liquid evaporation system of a heat pump,

[0011] Power generation can be performed by utilizing the heat medium evaporation system, the compression system, the heat exchange system, etc. of the material heat energy resource utilization system proposed by the present inventor. Further, it is also possible to utilize cold heat and warm heat generated accompanying the exchange of heat in the present system device as effective resources.

In the case of the compression system of the present invention, it is also possible to use solar cell power or wind power as power.

Incidentally, as the external heat source of the system of the present invention,
When using fluid substances such as air, rivers, and seawater, these substances absorb solar energy (heat and light) and are continuously supplied with energy by convection. That is, it becomes an effective total solar energy effective utilization system.

Hereinafter, the present invention will be described in detail with reference to the drawings.

With the outer and inner cylinders in contact and the inner cylinder rotating in a planetary fashion, with a spiral partition with variable pitch on the surface of the inner cylinder, with a mechanism that revolves while forming an independent airtight chamber consisting of the partition and the inner and outer cylinders I have.

FIG. 2 is a schematic diagram of an example of an apparatus application system of the present invention. In the figure, examples of vaporization of a liquid material, adiabatic expansion and low pressure of high-pressure steam, constant volume heating, adiabatic compression and the like are shown. Here, the external heat source is a natural environmental substance such as air, seawater, or a river, and high-pressure carbon dioxide gas which is normal at this temperature is set as a heat medium.

[0027]

According to the novel thermo-hydraulic power conversion system and the apparatus of the present invention, when the pitch of the spiral partition is widened from the entrance to the exit, the high-pressure gas is converted into a low-pressure gas by adiabatic expansion, or a liquid substance is converted. It can be used for a system that expands its volume by heating and evaporating it, and the volume expansion can be converted into rotational energy to generate power with high efficiency. When the pitch of the spiral partition is not changed, constant volume heating is possible, and compression can be performed by a device for reducing the pitch of the spiral partition. Moreover, by exchanging heat using an external heat source outside the outer cylinder, various heat resource energies can be converted into effective power (exergy). Since no pollutants are generated when these types of energy are generated, it is extremely effective in protecting the global environment.
