Abstract

The invention discloses a photo-bioreactor device, which comprises a spiral pipe and a first heat preserving cover which are both made from transparent materials, wherein a photosynthetic microbe culture solution is accommodated in the spiral pipe; a heat preserving fluid is circulated in a cavity inside the first heat preserving cover; and the first heat preserving cover is used for keeping the photosynthetic microbe culture solution in the spiral pipe in a preset temperature range. According to the photo-bioreactor device disclosed by the invention, the heat preserving cover is provided to ensure that the photosynthetic microbe culture solution can be kept at a suitable temperature, therefore, the fast growth of photosynthetic microbe cell is guaranteed, the light utilizing efficiency of the photosynthetic microbe is increased and the photosynthetic microbe yield is increased. In addition, a light source is arranged inside the photo-bioreactor device disclosed by the invention to ensure that extra light is provided for the photosynthetic microbe culture solution from inside, therefore, the light interception probability of the photosynthetic microbe cell can be increased and the overall yield is increased.

Description

technical field [0001] The invention relates to a photobioreactor device. Background technique [0002] Microalgae is a photoautotrophic organism, and light is one of the main limiting factors affecting its biomass in the process of microalgae autotrophy. The existing photobioreactor has the problem of receiving strong light on one side and weak light on the other side due to uneven light receiving. Microalgae cells have uneven chances of receiving light, which affects the light utilization efficiency of microalgae cells. [0003] Microalgae need a stable and suitable temperature to achieve sustained and rapid growth. However, the existing photobioreactors fluctuate greatly due to the change of the external environment temperature, and cannot maintain the stable and suitable temperature required for the growth of microalgae. Under the constantly changing temperature conditions, the microalgae cells cannot maintain a rapid growth state, thus The light utilization efficienc...
