Microalgae cultivation module and large-scale microalgae factory cultivation system

Abstract

The invention relates to a microalgae cultivation module and a large-scale microalgae factory cultivation system. The microalgae cultivation module comprises a box-type housing, wherein a culture solution leading-in opening is formed in the box-type housing, and at least one externally connected carbon dioxide vent tube with a plurality of vent holes is formed in the bottom of a cavity of the box-type housing; the side wall of the lower part of the box-type housing is connected with a collection port for collecting an algae liquid in the box-type housing, and at least one stirring device arranged in a culture solution is arranged in the box-type housing; a plurality of LED (Light Emitting Diode) lamps for lighting are also arranged in the box-type housing. The large-scale microalgae factory cultivation system mainly comprises at least two microalgae cultivation modules, a solution replenishment mechanism, a carbon dioxide supply mechanism, a temperature control device and a PH adjustment mechanism, and is characterized in that the microalgae cultivation modules are connected in a parallel, serial or combination manner. The microalgae cultivation module and the large-scale microalgae factory cultivation system provided by the invention have the characteristics of simple structure, convenience in operation and cleaning, controllable culture conditions, large culture volume per unit of land and the like.

Description

technical field [0001] The invention relates to a microalgae cultivation module and a microalgae large-scale factory cultivation system, belonging to the technical field of photobioreactors for microalgae cultivation. technical background [0002] Microalgae are the earliest organisms that appeared on the earth. They are tiny, ranging from a few microns to tens of microns, and can only be observed under a microscope. Microalgae are rich in species, fast in reproduction, rich in nutrients and various biologically active substances, and are easy to artificially reproduce and have a short reproduction cycle. Therefore, they are widely used in food, medicine, health products, cosmetics, aquaculture bait, feed additives, biological It has broad application prospects in pesticide, chemical industry, environmental protection and other fields. [0003] In recent years, the industrial cultivation of microalgae has gradually emerged, especially the cultivation of some high value-adde...

AI Technical Summary

Problems solved by technology

At present, most closed reactors are flat or tubular and installed indoors or outdoors. They occupy a large area, have low land utilization, high management costs, and a lot of money wasted on infrastructure construction, resulting in a significant increase in the cost of microalgae cultivation.
