Technical Field

[0002] Algae plants are a relatively primitive and ancient type of low-level autotrophic organisms. They have a simple structure and no differentiation of roots, stems, and leaves. They are mostly single-cell, group, or multi-cell thallus, with great differences in size. They contain photosynthetic pigments and can photosynthesize. There are about 30,000 species of them, which are mainly distributed in fresh water or sea water. Excessive reproduction of some species can cause red tides, algal blooms, and other phenomena. At present, the existing spirulina cultivation is mainly carried out in greenhouse pools. The circulation of algae liquid is mainly based on plate-type instantaneous displacement of algae liquid circulation, followed by open spirulina cultivation in lakes and seas. The harvesting of spirulina is mainly based on manual washing, filtering, dripping, and scraping. The steps are cumbersome, time-consuming, and laborious. In addition, the existing open-type greenhouse spirulina cultivation pools have technical problems such as large footprint, pollution of aquaculture water, slow and uneven water circulation inside the device, and difficulty in controlling various indicators inside the device.

[0003] Therefore, how to provide a three-dimensional pipeline enclosed edible microalgae cultivation device and its use method with small footprint, no aquaculture water pollution, fast and uniform water circulation inside the device, and easy control of various indicators inside the device is one of the technical problems that need to be urgently solved in this field.
