発明の名称 (英語) SOLAR HEAT COLLECTION DEVICE PROVIDED WITH FLUIDIZED BED, AND METHOD FOR COLLECTING SOLAR HEAT USING SAME NEW
発明の概要(英語) Provided is a solar-heat-collecting fluidized bed with which it is possible to efficiently realize an internally circulating flow and an externally circulating flow of particles. This solar-heat-collecting device 1 comprises a heat collection container 2 provided with a fluidized bed 3, an irradiation unit 4, and a gas introduction unit 5. The fluidized bed 3 comprises first and second opening parts 31, 32, a first partition plate 33, first and second flow spaces 34, 35, and particles P. The heat collection container 2 furthermore comprises at least one of: a particle introduction opening 6 and a particle discharge opening 7 for introducing and discharging the particles P, respectively; and first and second loop seal parts 8, 9 connected to the fluidized bed 3. The first loop seal part 8 connects the particle introduction opening 6 and the first flow space 34 of the fluidized bed 3, and supplies the particles P to the first flow space 34. The second loop seal 9 connects the second flow space 35 of the fluidized bed 3 and the particle discharge opening 9, and supplies the particles P within the second flow space 35 to the particle discharge opening 9.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, solar light collection type using the heat energy storage technology are actively studies.In this method, the heat engine is not subject to the constraints of the Carnot efficiency is not necessary, inexpensive and highly efficient energy storage is applicable to natural and have garnered attention as a new technology.
The inventors of the present invention, so far, in the inside of the fluidized bed can be generated by the circulation water and a thermal decomposition device or solar heat storage device has been proposed (Patent Document 1, reference 2).
Patent Document 1 is, as shown in Fig. 7, a second hydrothermal decomposition apparatus 100 in the formula column 103 is provided on the bed, each column 101,102 between the metal oxide particles P in cycling, thermal reduction reactor 101 as one of the column, the other column 102 (oxide) the thermal decomposition of water according to the present invention as used in a reactor.
However, the technique of Patent Document 1, the one reaction (reduction oxidation) 2 all of the second column 103 of the fluidized bed type one is generated inside the system, one 2 cannot be completely separated from the reaction, higher efficiency in each reaction is difficult to aim.
In addition, Patent Document 1 disclosed a solar cell 103 of the fluidized bed of heat storage device is used as a heat collection vessel, collecting the solar light 100 emitted from the device S in the upper window 104, the particles in the fluidized bed 103 by directly heating the P, and P to a layer of sensible heat can be distributed throughout the particles, the heated particles P is extracted for storing in a separate container not shown in, solar heat and batch processes, reducing the efficiency of the heat was caused.
In addition, the inventors of the present invention, in Patent Document 2, Patent Document 1 is different from the structure of the storage device is disclosed and includes a fluidized bed and, in particular, a large-scale heat collection, accumulation 3 of the Patent Document 2 for example (see also 4 and the corresponding drawing) is, the heat collecting container and separated from the heat storage container, these containers between the circulating particles in the storage device disclosed in the art.
However, Patent Document 2 of a device according to the 3 embodiment, the heat collecting in the container, the circulating flow within the fluidized bed of particles causes a heat collection effect of the particles can be confirmed, the heat collecting in the heat storage container from the container to heat the particles and the particles in the connecting transport path is successively supplied, it is difficult in practice.That is, the heat collecting part of the intracavity circulating in a vessel to separate the particles, the heat storage container and connected to a conveying path so as to be actually supplied to the flow of the method create (heat collection container-storage container-heat collection container of the heat is circulated outside the appropriate particles) is, it is not yet solved.
