Abstract

PROBLEM TO BE SOLVED: To provide the subject apparatus that can satisfactorily grow algae as chlorella, as it decreases the carbon dioxide in the air by introducing carbon dioxide in the air into the culture mixture of a kind of alga by means of an gas introduction means, as the culture mixture of the alga is irradiated with light. SOLUTION: A liquid culture mixture of an alga 2 is charged in a water tank 1, and irradiated with the light for photosynthesis of the alga from a light source as emission diodes, while carbon dioxide is supplied to the culture mixture by pressure-feeding the air into the culture mixture by using an air- introducing means. The air inhaled from the inlet opening 23 of the blower 19 is introduced through flexible inlet tubes 20, 21, 22 into the culture mixture 2.

ない第３の欠点がある。However, the above-mentioned apparatus has a first disadvantage that the growth of chlorella is not sufficient and is not efficient. The inventor of the present invention has investigated the cause, and found that this device irradiates the chlorella culture solution with light, but does not supply carbon dioxide, so that photosynthesis is not sufficiently performed. Therefore, it is conceivable to burn fossil fuel and introduce carbon dioxide contained in the exhaust gas into the water tank, but there is a second disadvantage that the cost increases. Furthermore, a large amount of carbon dioxide is present in the atmosphere, causing global warming, but the above-described device requires carbon dioxide, but does not effectively utilize the above-described atmospheric carbon dioxide. There is a third disadvantage.

In culturing microalgae, the present device 24 arranges the light source 7 for irradiating a specific wavelength directly in the culture solution 2, and effectively uses light not only by direct illumination but also by reflection of light by the water tank 2.

Algae can be efficiently grown. Moreover, by arranging the light source 7 in the culture solution 2, heat deviation of the light source 7 can be eliminated, and microalgae can be grown (grown / cultured) efficiently and effectively. In the carbon dioxide reduction device 24, photosynthesis of microalgae is performed by the following reaction formula.

For photosynthesis, light intensity, wavelength, water temperature, and carbon dioxide supply are important conditions. However, the light intensity is controlled by the number and current of the light emitting diode lamps 9 constituting the light source 7, the wavelength is controlled by the light emitting wavelength of the light emitting diode lamp 9 itself, and the water temperature is controlled by a heater (not shown) in the water tank 1. The supply amount of carbon dioxide is controlled by the amount of air blown by the blower 19, and all of the above conditions can be controlled.

As a result, carbon dioxide in the atmosphere is reduced, thereby suppressing global warming and the like. Since the fossil fuel is not burned and the exhaust gas is used as in the related art, the carbon dioxide itself in the atmosphere is taken in, so that the cost is low.

The air containing carbon dioxide was fed at a rate of 3.6 liters / minute with 5 million cells / cc of soculata. The light-emitting diode lamp 9 was arranged so that the light-emitting portion was completely immersed in the culture solution 2, and was repeatedly turned on and off every three hours. Fig. 3 shows the characteristics of one week.
The number of cells on the vertical axis is a coefficient calculated by the Birke-Tiruku hemocytometer, the unit is (10,000 cells / cc), and the horizontal axis is the number of days (days).

The case where no foil was used (characteristics C and D) is shown. The difference between the characteristics C and D was the difference in the number of light emitting diode lamps arranged outside the beaker. In the characteristic C, only 80 lamps were used, and the initial maintenance was barely possible. In characteristic d, the effect of growing a monochromatic light source was confirmed using 350 light emitting diode lamps.

From this equipment and results, even when illuminating from the outside, a monochromatic light source is more effective than a white light source, and even if a monochromatic light source is used, the reflection of the wall surface and supply of carbon dioxide increase the proliferation. It will be understood.
