Description

technical field [0001] The invention belongs to the field of microalgae biotechnology, and particularly relates to a high-efficiency modular algae photobioreactor, which utilizes the high-efficiency photosynthesis of algae and is suitable for efficient production of algae biomass and CO in life support systems for space flight and submarine navigation. 2 Fixed and O 2 regeneration. Background technique [0002] Since the beginning of manned space exploration, the controlled ecological life support system has been paid attention to as the basis of manned spaceflight, and the CO 2 Remove and O 2 Regeneration is a key technology in the study of controlled ecological life support systems. Microalgae have become one of the important organisms in the study of controlled ecological life support systems due to their good adaptability, simple cultivation, stable operation, and efficient and rapid production of food and oxygen required by space crew. The growth of microalgae depend...

Problems solved by technology

At present, most of the research is carried out by dynamic centrifugation, and hollow fiber membrane is also used. However, centrifugation depends on the centrifuge, which is unfavorable for space flight requirements in terms of power consumption and volume weight. The hollow fiber membrane method has low efficiency, It is easy to block and other problems, so it is urgent to develop a stable and efficient gas-liquid separation technology for space algae reactors

[0007] Traditionally designed reactors integrate functional devices such as cultivation, stirring, gas separation, and measurement and control as a whole. The design is complex, and each component cannot be operated independently or easily replaced, which greatly reduces the stability of the equipment and increases the complexity of operation.
