本实用新型涉及一种光生物反应器，特别是一种微藻培养的光生物反应器。The utility model relates to a photobioreactor, in particular to a photobioreactor for cultivating microalgae.
背景技术Background technique
微藻是一类分布极广的低等自养生物，其具有光合作用效率高、零净碳值、生长周期短、易培养、油含量高等优点，是一种极具前景的生物柴油原料。其对环境条件要求不高，适应能力强，且不需要占用耕地面积，单位产量高，有些微藻的含油量可达50％（质量分数）以上。与陆生植物相比，微藻单位面积产油量是油料植物产油量的数十倍。此外，微藻中含有极其丰富的生物质资源，是珍贵的高价值药品和化学品的可靠来源，在保健品及医药用品应用上具有很大的潜力。部分微藻还能应用于食品添加剂以及功能性食品的开发。因此，产业化培养微藻成为了当前研究的热点问题。Microalgae is a kind of low-level autotrophic organisms with wide distribution. It has the advantages of high photosynthetic efficiency, zero net carbon value, short growth cycle, easy cultivation, and high oil content. It is a promising biodiesel raw material. It does not require high environmental conditions, has strong adaptability, does not need to occupy arable land, and has a high unit yield. The oil content of some microalgae can reach more than 50% (mass fraction). Compared with terrestrial plants, the oil production per unit area of microalgae is dozens of times that of oil plants. In addition, microalgae contain extremely rich biomass resources, which are reliable sources of precious high-value drugs and chemicals, and have great potential in the application of health care products and medical supplies. Some microalgae can also be used in the development of food additives and functional foods. Therefore, the industrial cultivation of microalgae has become a hot topic in current research.
目前，国内外应用较多的大规模微藻培养主要以密闭式光生物反应器为主。其中，管式光生物反应器材料价格相对较低，且其单位光照面积较其他光生物反应器更大，微藻生长速率更快，是目前最适用于室外大规模培养的光生物反应器之一。管式光生物反应器的限制因素在于其管段长度受溶解氧浓度、二氧化碳浓度及pH值的制约较大，反应器中微藻光合作用所产生的氧气若不能及时排出，反而会抑制微藻生长。因此，如何改进管式光生物反应器使其内藻液溶氧能及时排出，对于增大反应器管段长度、实现其产业化培养有重要意义。At present, the large-scale microalgae cultivation that is widely used at home and abroad is mainly based on closed photobioreactors. Among them, the material price of tubular photobioreactor is relatively low, and its unit light area is larger than other photobioreactors, and the growth rate of microalgae is faster. It is currently one of the most suitable outdoor large-scale cultivation photobioreactors. one. The limiting factor of the tubular photobioreactor is that the length of the tube section is greatly restricted by the concentration of dissolved oxygen, carbon dioxide concentration and pH value. If the oxygen produced by the photosynthesis of microalgae in the reactor cannot be discharged in time, it will inhibit the growth of microalgae. . Therefore, how to improve the tubular photobioreactor so that the dissolved oxygen in the algae liquid can be discharged in time is of great significance for increasing the length of the reactor tube section and realizing its industrial cultivation.
