Microalgae tube type reactor and system thereof

Abstract

The invention provides a microalgae tube type reactor and a system thereof, and belongs to the field of bioengineering. The microalgae tube type reactor comprises a stirring and circulating mechanism, wherein the stirring and circulating mechanism comprises a stirring internal mechanism and a stirring external mechanism; the stirring internal mechanism comprises a fixed guide rod and a stirring ball; the stirring external mechanism comprises a guide rail, a traction belt and a guide magnetic block; a guided magnetic block is embedded in one side, which is tangent with the inner wall of a pipeline, of the stirring ball; and the guided magnetic block is arranged corresponding to the guide magnetic block and can realize magnetic guide movement by a pipeline. A microalgae tube type reaction system comprises the microalgae tube type reactor; and an automatic valve is arranged at a liquid discharge port. The microalgae tube type reactor realizes stirring and circulation of microalgae by utilizing movement of the stirring ball; compared with the prior art, mechanical damage to the microalgae caused by mechanical stirring is greatly reduced; the microalgae tube type reaction system further perfects the microalgae tube type reactor.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a microalgae tubular reactor. Background technique [0002] The existing tubular photobioreactor has the following disadvantages: only a single mechanical pump is used as the circulation power, and the mechanical shear force generated by the long-term mechanical pump circulation is very harmful to the microalgae cells, which is easy to kill Dead algae cells, unable to make it grow normally. [0003] The purpose of stirring and circulating the algae liquid is to reduce the shading effect between cells and form a uniform concentration of nutrients and gas around the algae during the growth process, effectively eliminate the accumulation of dissolved oxygen in photosynthesis, and prevent the algae from sinking and anaerobic decomposition. , Improving the efficiency of photosynthesis, promoting gas-liquid mass transfer, and accelerating the growth of algae are the main methods to achie...

[0002] The existing tubular photobioreactor has the following disadvantages: only a single mechanical pump is used as the circulation power, and the mechanical shear force generated by the long-term mechanical pump circulation is very harmful to the microalgae cells, which is easy to kill Dead algae cells, unable to make it grow normally

The air-lift cycle is suitable for shear-sensitive algae cell culture due to its small shear force, but it has problems such as high power consumption when used in large-scale culture. Pump cycles such as centrifugal pumps and rotor pumps, when the pump is working, the algae cells will pass through the impeller. Damaged to varying degrees, especially the high-speed rotating impeller or rotor will break the spirulina filaments or algae cells, the higher the concentration of the algae liquid in the culture solution, the greater the damage, and the photosynthesis rate of the algae will also be affected. will have adverse effects
