Membrane type photobioreactor for enhancing microalgae culturing

Abstract

The invention discloses a membrane type photobioreactor for enhancing microalgae culturing. The membrane type photobioreactor comprises an external light source, a bottom plate, an inner sleeve and an outer sleeve, wherein the inner sleeve and the outer sleeve are vertically arranged on the bottom plate; the outer sleeve is positioned on the outer side of the inner sleeve and surrounds the inner sleeve; the top end of the outer sleeve is horizontally provided with a transparent top cover plate, the top of the outer sleeve is provided with a plurality of air outlets and the bottom of the outersleeve is provided with a discharge port; the bottom of the inner sleeve is provided with a plurality of exchange holes; the bottom plate is provided with an air inlet which is surrounded by the inner sleeve; the air outlets are positioned above the top end of the inner sleeve; the bottom plate is vertically provided with a membrane component which is positioned inside the inner sleeve; and the bottom edge of the membrane component is hermetically fixed with the bottom plate and surrounds the air inlet. The membrane type photobioreactor for enhancing microalgae culturing has the advantages ofsimple structure, simplicity and convenience in operation, stable performance, larger specific surface area and light transmission efficiency; and by using the membrane component, the gas is uniformly distributed, and the photobioreactor can be independently used or connected with a track pool for amplified culturing of the microalgae.

Description

technical field [0001] The invention relates to the technical field of algae cultivation reactors, in particular to a membrane-type photobioreactor for strengthening microalgae cultivation. Background technique [0002] Microalgae are a kind of autotrophic plants widely distributed in land and ocean, rich in nutrients and high in photosynthetic utilization. The polysaccharides, proteins, pigments, etc. produced by cell metabolism make them useful in the fields of food, medicine, genetic engineering, and liquid fuels. Very good development prospects. As a key to cracking the energy crisis in the post-petroleum era, microalgae has the advantages of large production capacity, no pollution, and renewable, and its development prospects are very bright. However, since the research and application of domestic energy microalgae are still in their infancy, there are still many problems that are difficult to solve, and it is also essential for the research and development of photobio...

Problems solved by technology

However, compared with the two reactors, the airlift type is more suitable for microalgae cultivation, because the bubbling reactor will have uneven cell density distribution in the axial direction, which may easily cause starvation or even death of some microalgae cells
