1 to 14 is a view showing a microalgae culture apparatus according to an embodiment of the present invention.

As shown, the microalgal culture apparatus according to the present invention includes a plurality of culture tanks (11, 12, 13, 14), the plurality of culture tanks (11, 12, 13, 14) are exhaust gas, such as a factory It is placed on the rooftop or outdoors of the building where it occurs.

Each culture tank (11, 12, 13, 14) is made of a transparent material such as transparent synthetic resin, glass, etc. to facilitate the transmission of sunlight, and thus the photosynthesis of microalgae in the culture tank (11, 12, 13, 14) It is configured to facilitate. In addition, a culture medium tank 19 is disposed adjacent to the culture water tanks 11, 12, 13, 14 to supply a culture solution such as seawater.

A plurality of culture tanks (11, 12, 13, 14) are arranged at different heights, as shown in Figure 3, thereby forming a natural drain between the culture tanks (11, 12, 13, 14) It is configured to be. As described above, since a plurality of culture tanks 11, 12, 13, and 14 disposed at different heights do not need to use a separate electric device such as an electric motor for natural drain, carbon dioxide is generated through the use of electric energy. There is an advantage that can be prevented.

In particular, the plurality of culture tanks (11, 12, 13, 14) are arranged in a cascade, the plurality of culture tanks (11, 12, 13, 14) are communicatively connected to each other through a plurality of drain pipes (15) , Each culture tank (11, 12, 13, 14) is supported by a support frame (11a, 12a, 13a, 14a). Then, the plurality of culture tanks (11, 12, 13, 14) is protected by a protection house 50, the illumination securing unit 51 such as a fluorescent lamp is installed on the ceiling side of the protection house 50, ensuring such illumination The unit 51 is arranged on top of each culture tank (11, 12, 13, 14) is optimized for improving the culture efficiency of each culture tank (11, 12, 13, 14) without being affected by external conditions It is configured to secure roughness (about 300 ~ 400 lux).

In FIGS. 1 to 4, four culture tanks 11, 12, 13, and 14 are illustrated, but the present invention is not limited thereto, and may be variously designed to be less or more.
