Embodiment 1

[0086] The photobioreactor provided by Embodiment 1 of the present invention is as figure 1 As shown, it includes: several containers 110 .

[0087] Wherein, the structure of the container 110 is as figure 2 As shown, the shape of the container 110 is like a tank with one end closed, one end is an open end, and the other end is a closed end. length of the side fence 113 .

[0088] The above-mentioned several containers 110 are stacked and staggered, and the open end of the container 110 on the upper layer is placed corresponding to the closed end of the container 110 on the next layer; The sides of 113 are joined to form a photobioreactor with fluid communication.

[0089] That is to say, when assembling the photobioreactor, first get a container 110 and place it on the lowermost layer, and then get another container 110 and place it on the lowermost container 110 as the second layer; the opening of the container 110 of the second layer The closed ends of the containers 1...

Embodiment 2

[0099] The photobioreactor provided by the second embodiment of the present invention is as Figure 6 As shown, the difference from the photobioreactor in the first embodiment is that the photobioreactor also includes at least one column 120 in addition to several containers 110 .

[0100] The columns 120 are arranged outside the side walls and / or outside the closed baffles of the assembled containers 110 to maintain the stability of the assembled photobioreactor. The columns 120 may not be connected and fixed with the reactor, but only play the role of support, stability and guidance, which expands the selection range of materials for the columns 120 and reduces the cost.

[0101] After the number of layers of the container 110 is increased, the stability of the reactor is weakened when the number of layers is relatively small. In order to ensure the overall stability of the photobioreactor, a column 120 can be set on the periphery of the photobioreactor to ensure the reactio...

Embodiment 3

[0104] The photobioreactor provided by the third embodiment of the present invention is as Figure 7 As shown, the difference from the photobioreactor in the second embodiment is that the photobioreactor not only includes several containers 110 and several columns 120 , but also includes: at least one support plate 130 connected to each column 120 .

[0105] A cross-sectional view of the bioreactor is shown in Figure 8 shown. Wherein, the support plates 130 at the same height on different columns 120 form a support plate group, and several containers 110 are divided into several container groups by the support plate group; each support plate group is used to support a group of containers located above itself Assembled container group.

[0106] After the number of layers of the container increases, the weight borne by the container 110 at the bottom of the reactor will also increase. In order to reduce the load on the bottom reactor, the support for its supporting function c...

Abstract

Provided are a photo-bioreactor and a method for photo-biological cultivation. The photo-bioreactor comprises at least two containers layered vertically, wherein any two adjacent containers are connected with each other, thus the photo-biological culture fluid can flow from the container of top layer to the container of bottom layer one layer by one layer.

Description

technical field [0001] The invention relates to the technical field of photosynthetic microorganism cultivation, in particular to a photosynthetic microorganism cultivation method and system for cultivating photosynthetic microorganisms using an assembled photobioreactor, a photobioreactor and a container. Background technique [0002] The growth and reproduction of photosynthetic microorganisms, especially microalgae and cyanobacteria (referred to as algae), mainly rely on simple minerals. Through photosynthesis, algae use light energy (such as sunlight and artificial lighting) to convert water and carbon dioxide into high-value organic compounds such as pigments, proteins, fatty acids, sugars, and secondary metabolites. Algae show stronger growth potential than higher plants because of their extremely high light and nutrient utilization efficiency. [0003] By utilizing the latest breakthroughs in molecular biology, metabolic engineering, and functional genomics research,...
