Problems solved by technology

However, there are a series of problems in this closed polyethylene transparent plastic bag photobioreactor, such as: there is a "dead zone" in a static state (mainly comprising a large number of inevitable wrinkles at the bottom of the transparent plastic bag formed by the dead zone) 4, and the dead zone formed by the bottom peripheral area that cannot be effectively stirred 7), resulting in the inability of the algae fluid to flow sufficiently around the bottom of the photobioreactor, thus further leading to incomplete disinfection, uneven nutrient distribution, and cells in the dead zone 4, 7 Adhesion to the wall is severe and gradually precipitates and stores or even dies. Oxygen analysis and carbon dioxide exchange compensation are also affected. The comprehensive result reduces the efficiency of microalgae cultivation
At the same time, this columnar photobioreactor is also very easy to tilt sideways, resulting in lodging
The above defects greatly reduce the application of this type of closed photobioreactor in the development of microalgae resources.

Embodiment 1

[0030] As shown in Figures 2 to 3, a fixed base 8 is built using sand, stone, cement, etc., and the center of the fixed base 8 is depressed: the lower end of the depression is an inverted right cone, including a concave cone tip 81 and a concave cone. The cone bottom part 82, the circumference of the cone bottom is 150.7cm, the diameter is 48cm, the side length of the cone is 33.9cm, the cone height is 24cm, and the cone tip is at an angle of 90 degrees; (150.7cm).

[0031] Long 150cm, wide 120cm barbed wire is folded in half and surrounded into a cylinder, fastened with a thin rope, as a fixed support network frame 2, the cylinder-shaped support network frame that surrounds is high 120cm, diameter 48cm, circumference 150cm.

[0032] Take a polyethylene double-layer transparent plastic tube with a thickness of 10 wires and a width of 75 cm, cut it every 200 cm, and seal it into a plastic bag with a sealing machine, one end is isosceles sealed from the middle to the two sides, ...

Abstract

An optical bioreactor for culturing microalga is composed of concave fixing base with conic shape, supporting mesh frame, transparent plastic bag, and inlet and outlet pipelines. Its advantages are high installation stability, uniform distribution of nutrients and sufficient disinfecting and gas exchange.

Description

technical field [0001] The invention belongs to the field of microalgae biotechnology, and relates to a photobioreactor device capable of effectively stirring in microalgae cultivation and avoiding dead angles in algae liquid, which is used for cultivating microalgae to produce related products or provide 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 particularity in terms of germplasm, ecological distribution, genetic information, biochemical composition, and metabolic pathways, which further determine their potential nutritional and pharmaceutical value. Humans may develop a large number of structurally specific high value-added bioactive ingred...
