Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like photosynthetic reaction tank device, and more particularly to a plate for storing microalgae, photosynthetic bacteria, etc. (hereinafter referred to as photosynthetic microorganisms) and performing a photosynthetic reaction under sunlight. A photosynthetic reaction tank device.

[0002]

2. Description of the Related Art Photosynthetic microorganisms have a property of absorbing carbon dioxide in the atmosphere, performing photosynthesis, and rapidly growing. Some photosynthetic bacteria have a wastewater treatment function and a hydrogen production function. Focusing on these properties, the development of technologies for using photosynthetic microorganisms to solve environmental pollution problems and the problem of limited natural resources has been promoted. In particular, in cities, it is desired to develop technologies for utilizing reusable resources such as sunlight and other environmentally friendly technologies.

[0003]

In order to utilize photosynthetic microorganisms, a culture tank facility (hereinafter, sometimes referred to as a photosynthetic reaction tank) is indispensable. However, conventional photosynthesis reactors for mass culture are horizontally installed and the depth is limited to the reachable range of light, so orthodox mass culture requires vast unused areas such as deserts and oceans. The construction was premised on. On the other hand, when constructing a large-scale reaction tank facility in a city, there are difficulties from the ground, and various types of high-efficiency, area-saving culture devices have been created to solve this difficulty. . As an example, a method of installing a reaction tank inside a building or in an underground space has been proposed. However, this method has a problem that a separate light condensing device or the like for guiding outdoor sunlight to the inside is required. Although a method of installing a reaction tank on the roof of a building has been proposed, the roof of the building is already used for a water tank, an air conditioner, a heliport, and the like, and a sufficiently large installation area cannot always be secured.

[0004] The inventor paid attention to the outer wall of a building. The exterior walls of buildings have traditionally been used to protect the indoor environment from adverse outdoor conditions such as rain, strong winds and excessive solar radiation, and are passive features that repel the interference of outdoor natural conditions that are undesirable for human habitation. Has been fulfilled. However, they have not fulfilled the active function of actively utilizing sunlight and other resources incident on the outer wall surface. If a photosynthetic reaction tank is installed on the outer wall surface of the building to recover the energy of sunlight, the above-mentioned land problem can be mitigated, and at the same time, contribution to efficient use of the building (intelligentization) can be expected. Heretofore, there has not been developed any technology for practical use of a photosynthesis reaction tank that can be attached to a vertical support such as an outer wall of a building.

Further, in the conventional outdoor culturing apparatus, since a photosynthetic reaction tank for microorganisms and a heat exchanger and a gas-liquid separation part are separately arranged, a device for circulating the culture liquid outside the reaction tank is required. As a result, stagnation occurs in the culture solution, and the structure is complicated, so that maintenance at the time of fouling is difficult. Accordingly, an object of the present invention is to provide a plate-like photosynthesis reaction tank device that can be supported at various angles including vertical.

[0006]

4) containing the photosynthetic microorganisms and water, and passing the heat medium through the other layer 24 (or 23) to control the temperature of the water in the one layer 23 (or 24). In a more preferred embodiment, the stirring means 9 is provided in the plate-like cylindrical body 3 or the one layer 23 (or 24).
Is provided.

[0008] The reaction tank apparatus of the present invention can be a minimum unit for simultaneously culturing microorganisms, photosynthesizing reaction, heat exchange, and gas-liquid separation in one reaction tank. For example, the light receiving surface of each unit is square, and the square units are arranged on the surface of the support W without gaps, so that the wide surface of the support W can be covered with the photosynthesis reaction tank, and effective use of sunlight can be achieved. If both ends of the plate-like cylinder 3 can be opened,
It is easy to clean the inner wall of the reaction tank that has become dirty after use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, both ends of a plate-like cylindrical body 3 are sealed with a pair of lids 5 to form a photosynthetic reaction tank 2, and the reaction tank 2 is fixed by a fixing means 15 such as a hexagon screw. The plate-like photosynthesis reaction tank device 1 is formed by attaching to the plate. The peripheral wall of the cylindrical body 3 is made of a transparent material such as transparent glass, acrylic resin, and polycarbonate. The photosynthetic microorganisms and water are stored in the cylindrical body 3 before closing the both-end openings, or the photosynthetic microorganisms and water are stored in the cylindrical body 3 from the entrances 16a and 16b provided in the lid 5 after closing the both-end openings. As needed,
Nutrients and the like necessary for culturing the photosynthetic microorganism can be contained in the water.

In the example of FIG. 1, the reaction tank device 1 is fixed to the support W by coupling the leg 6a of the fixing means 6 and the fixing means 21 on the support W. An example of the support W is a vertical structure wall such as an outer wall of a building where sunlight enters, a soundproof wall of an expressway, or a windproof wall. However, the reaction tank apparatus 1 of the present invention can be used horizontally, and even in this case, the efficiency of the photosynthesis reaction can be optimized by adjusting the inclination angle of the reaction tank 2 described later. In order to avoid precipitation of microorganisms, a stirring device 9 can be provided in the reaction tank 2. In addition, since the light receiving area can be increased and the thickness in the direction intersecting with sunlight can be made sufficiently thin, a region (dead space) in the reaction tank 2 where light does not shine can be minimized.

For example, the reaction tank device 1 can be appropriately attached to the outer peripheral wall of a building, and microorganisms and water can be moved between the reaction tanks 2 according to the direction of the sun. In this case, the ports 16a and 16b of each reaction tank device 1 are connected in order. By adjusting the mounting height of each reaction tank device 1, replacement of microorganisms and water can be simplified by utilizing gravity.

Further, photosynthetic microorganisms having a wastewater treatment function and a hydrogen production function are housed in the reaction tank 2, and hydrogen is produced together with the treatment of wastewater generated in the building by the reaction tank device 1 mounted on the outer wall of the building. it can. In this case, a carrier for supporting photosynthetic microorganisms can be provided in the cylindrical body 3.
Waste water is sent into the tank from an inlet 16a provided in the lid 5 of the reaction tank 2, and treated water is taken out of the tank from an outlet 16b. The treated water taken out can be reused in the building as middle water. The hydrogen gas generated in the tank is taken out of the tank through the vent 19a of the lid 5 and can be used as an energy resource. That is, by attaching the reaction tank device 1 to the building outer wall, an active role of wastewater treatment and energy production is given to the building outer wall, and it is possible to contribute to alleviation of the land problem and efficient use of the building.

Thus, the object of the present invention is to provide a "plate-like photosynthetic reaction tank apparatus which can be supported at various angles including vertical".

Due to the two layers in the cylinder 3, one layer 23 (or 24) is used as a microorganism culture tank (hereinafter, sometimes referred to as a culture layer), and the other layer 24 (or 23) is used as a temperature adjustment tank ( Hereinafter, it may be referred to as a temperature control layer.) However, the formation of two layers by the heat conductive partition 25b is not an essential requirement for the reaction tank apparatus 1 of the present invention.

FIG. 2A shows two transparent plates 25a, 25c and one heat conductive partition 25b, which are connected to four side edge spacers 26R1, 26L1, 2L.
An example in which a plate-like cylindrical body 3 (FIG. 2B) is formed by combining 6R2 and 26L2. Transparent plates 25a, 25c and heat conductive partition 25b
Are glass sheets, and the side edge spacers 26 can be made of acrylic resin. 1 and 2
As shown in (C), in order to prevent water leakage at the contact portion between the end of the plate-shaped tubular body 3 and the lid 5, an edge member 4 having a through hole 28 is interposed therebetween. That is, as shown in FIG. 2 (B), a concave portion having an inclined surface 27 which expands outward is formed on one side of each edge member 4 as an enlarged portion of a through hole 28, and the concave portion of the plate-like cylindrical body 3 is formed in the concave portion. The end portion is fitted, and the outer peripheral surface of the end portion of the tubular body 3 is sealed by the sealing member layer 30 previously applied to the inclined surface 27.
To the concave inclined surface 27 in an airtight manner. A packing groove is formed in the peripheral edge of the through hole 28 on the surface of the end member 4 opposite to the cylindrical body 3.
A packing 20 such as an O-ring is provided in the groove 29 (see FIG. 3A), and the lid 5 is hermetically attached to the edge member 4 via the packing 20. FIG. 2 (B) and FIG.
An arrow I in (C) indicates a direction in which each terminal in the length direction of the plate-shaped tubular body 3 is inserted into the edge member 4. Reference numeral 36 in the figure denotes an outer layer 23 and an inner layer 24 interposed between both ends of the heat conductive partition 25b and each lid 5.
5A shows a set of acrylic edge spacers to prevent communication between the spacers. The edge member 4 and the lid 5 are shown in FIG.
As shown in the figure, the fixing screw 18 can be detachably fixed.

FIG. 3A shows the appearance of the outer end face of the edge member 4 as viewed from the direction of arrow IIIA in FIG. 2B. A transparent plate 25a and two left and right side edge spacers 26R1, 26L1 are provided inside the cylindrical body 3.
And the edge spacer 36 (and the heat conductive partition 25b) define the inner layer 24, the transparent plate 25c and the two left and right side edge spacers 2

The inner layer 24 is formed by taking the heat medium in and out through the outlet 40b.
Is the temperature control layer 24. By transmitting the heat of the temperature control layer 24 to the culture layer 23 via the heat conductive partition 25b, the water temperature of the culture layer 23 can be controlled at, for example, 25 to 35 ° C. suitable for the growth of microorganisms. When resting the activity of the microorganisms at night, a low-temperature heat medium is fed into the temperature control layer 24 to lower the temperature of the culture layer 23, thereby reducing the activity of the microorganisms. As a heat medium of the temperature control layer 24, a heat medium for air conditioning in a building can be used. In the example of FIG. 1, the temperature control layer 24 faces the support and the culture layer 23 faces the atmosphere, that is, the sunlight incident side. However, the temperature control layer 24 can be directed to the atmosphere side. In this case, there is an effect of preventing the temperature of the culture layer 23 from rising by absorbing the heat rays by the temperature control layer 24 before the sunlight reaches the culture layer 23.

Sunlight can be taken into the cylindrical body 3 also from the opening 8. When the reaction tank device 1 is arranged to face the window on the outer periphery of the building, the opening 8 may be a window for taking in light and / or air from the outside. However, the fixing means 6 used in the reaction tank device 1 is not limited to one having the opening 8. FIG. 2 (C)
The edge member 4 has a stopper 31 to the mounting plate 7 or the like, and can be mounted to the mounting plate 7 by a relatively short stopper 31 instead of the mounting means 15 such as the long hexagon wrench screw in FIG. .

FIG. 6 shows an embodiment of a reaction tank apparatus 1 having fixing means 6 to which five plate-like photosynthesis reaction tanks 2 can be attached. The fixing means 6 shown in FIG. 6 includes a pair of parallel column members 6L and 6R attached to a support W such as a building wall or the like so that the inclination angle can be adjusted, and each cylindrical member 2 between the two column members 6L and 6R. And a group of shaft members 6H rotatably supporting the shaft member 6H. By adjusting the inclination angle θb (see FIG. 7) and adjusting the rotation angle θa (see FIG. 7) around the shaft member 6H, it is possible to adjust the incident angle of the sunlight rays entering each reaction tank 2. it can. FIG.
For example, it is possible to adjust the predetermined angle θb according to the change in the sunlight incident direction due to the season, and to adjust the rotation angle θa according to the change in the sunlight incident direction due to the weather.

Conventionally, it has been reported that when the light intensity is too high, not only the activity of the photosynthetic microorganisms decreases, but also the efficiency of the photosynthetic reaction decreases. The present inventors have experimentally confirmed that when sunlight in fine weather is incident on the plate-shaped surface of the photosynthetic reaction tank 2 at right angles, the light is too strong to obtain the maximum efficiency. From this experimental result, the rotation angle θa is adjusted so that the angle of incidence of the sunlight on the plate-like surface of the reaction tank 2 becomes a right angle in the cloudy weather shown in FIG. It has been found that by adjusting the rotation angle θa so that the incident angle becomes an acute angle or an obtuse angle in fine weather, the photosynthetic reaction efficiency of the reaction tank device 1 can be maintained high regardless of the season and weather.

Each reaction tank 2 shown in FIG. 6 is designed so that some of the reaction tanks 2 are not shaded by other reaction tanks 2 when the angle is adjusted.
