Abstract

The present invention belongs to the field of micro algae biotechnology, and is especially one kind of closed pipeline optical bioreactor plant for large scale culture of micro algae. The optical bioreactor plant includes transparent pipeline, gas analyzing unit, auxiliary pipe system, culture parameter sensing and controlling unit and economic micro algae. The present invention adopts large gas analyzing unit, parallel connected transparent pipes, mechanically drive water flow, mutual light blocking of cells, etc. to ensure the gas exchange inside the reactor for photosynthetic metabolism, reduce oxidation damage and light damage, replenish CO2 effectively, reduce the blocking of bubble column on water flow, and raise micro algae culturing efficiency and yield. In addition, the optical bioreactor plant may be established in place with sufficient sun light to utilize natural light effectively.

Description

technical field

[0001] The invention belongs to the field of microalgae biotechnology, and relates to a pipeline photobioreactor for cultivating microalgae. The device is a closed system, which can effectively block the contamination of harmful organisms; at the same time, the algae liquid can be stirred effectively to avoid the existence of dead angles; in addition, the gas exchange is sufficient, which can effectively compensate for carbon dioxide and resolve dissolved oxygen. The device can be used for large-scale cultivation of microalgae, production of related products or provision of aquaculture bait. Background technique

[0002] As an important part of primary productivity in the biosphere, microalgae are the only bait for the entire growth process (or specific developmental stages) of aquatic animals in the aquatic ecosystem or the bait for bait organisms. At the same time, microalgae are close to 50% of plant species, and have diversity, complexity and particulari...

Examples

Embodiment 1

[0038] 30-ton scale pipeline photobioreactor.

[0039] In a standardized plastic greenhouse (length 66m, width 10m, net area 1 mu of land), according to Figure 3A and Figure 3B, design a new microalgae scale cultivation photobioreactor.

[0040] First, build a large-scale gas analysis device 2 at both ends of the greenhouse. 50 circular parallel pipe connections 9 are respectively arranged on one side of the inner surface of each gas analysis device 2, the circumference of the connections is 36 cm, and the connections are evenly arranged. The pipe interface of the large-scale gas analysis device at the two ends requires remote correspondence, and the upper end of the large-scale gas analysis device is provided with a filtered compressed gas pipeline 4, a gas analysis pipeline 5, a discharge pipeline 6 and a material feeding pipeline 7. Filtered compressed gas (air or carbon dioxide enriched air) release pipeline port 41 is placed in the pipeline interface 9 of the gas analysi...
