High-efficiency microalgae culturing device based on plant bionics

Abstract

The invention discloses a high-efficiency microalgae culturing device based on plant bionics, belongs to the field of microalgae production and aims at providing a microalgae reactor with high efficiency in light collection and small occupied area so as to meet the demands of scale production of the microalgae. The high-efficiency microalgae culturing device disclosed by the invention is realized by the following technologies: a reactor comprises four parts, namely a root reactor, a stem reactor, leaf reactors and a guide pipe, wherein the root reactor is positioned at the bottom and is a collector of microalgae liquid; the stem reactor is a mixer of the microalgae liquid; the leaf reactors are arrayed on the stem reactor in a staggered way and is a place of which algae cells carry out photosynthesis; and a reactor system is connected through the guide pipe. The microalgae liquid in the root reactor is sucked into the stem reactor by the water pump and then injected into the leaf reactors; and after the reactor is filled with the microalgae liquid, the microalgae liquid is injected into the stem reactor and finally fed into the root reactor. The number of the leaf reactors is great; the leaf reactors are arrayed in a staggered way, are adjustable in angle and great in area-volume ratio; and the algae cells can be fully sensitized at the leaf reactors, so that the culturing efficiency is increased. The high-efficiency microalgae culturing device has the advantages of high sensitization efficiency of the microalgae liquid, small occupied area and high industrialization; and the high-efficiency microalgae culturing device is suitable for being used in various environments and especially suitable for culturing microalgae in north area of China in winter.

Description

technical field [0001] The invention relates to the field of microalgae cultivation system, in particular to a high-efficiency light-harvesting device for single-cell algae liquid based on plant structure bionics. Background technique [0002] In the context of the depletion of energy resources in human society, some microalgae have attracted much attention in recent years due to their high oil yield, rapid oil accumulation, and short production cycle, and have become one of the emerging hotspots in the field of bioenergy research. Research in this field in our country is still in its infancy. [0003] The cost of raw materials of algae accounts for more than 70% of the total cost of biodiesel production. Therefore, in the process of microalgae production, the key link is to promote the rapid growth of algae, so that the algae cells can reach the maximum productivity in the shortest time. At present, algae bioreactor has become the key equipment for high-efficiency, rapid ...
