Light bioreactor for culturing microalgae systematically

Abstract

The invention relates to a light bioreactor for culturing microalgae systematically, which comprises an in-parallel pipe group, a control valve, a pH value sensor, a temperature sensor, a light sensor, a water mist sprayer, a liquid level alarm, a pipe pump, an air inlet pipe, an exhaust pipe, a feed pipe, a discharge pipe, a microporous pipe, a liquid storage tank, a cool and heat exchanger, a control panel, a bracket, a lighting facility and the like, wherein the pipe group and the valve are effectively connected in a close way, specific surface area is enlarged simultaneously when the volume of microalgae is enlarged during culturing, and the invention has small ground occupation, effectively uses stereo space and has sufficient air exchange, and utilization rate is increased; during culturing, the invention monitors parameters such as temperature, pH value, concentration of a culture medium, lighting intensity, and the like in real time, provides the best condition for microalgae growth and metabolism, effectively reduces culturing time, avoids danger of outside harmful creatures, and decreases production cost. The bioreactor can be used for culturing microalgae cells in a continuous or semi-continuous way and producing microalgae protein, biodiesel or aquatic baits and other products.

Description

technical field [0001] The invention relates to the technical field of microalgae bioengineering, in particular to a photobioreactor for systematically cultivating microalgae. Background technique [0002] As an important renewable resource, microalgae have the outstanding characteristics of wide distribution, large biomass, high photosynthetic efficiency, strong environmental adaptability, short growth cycle, and high yield. The further development and utilization of microalgae will provide new resources, such as microalgae protein, biodiesel or aquatic bait. [0003] However, microalgae resources in nature are widely distributed and there are many types. The development of microalgae resources needs to be monocultured and systematically carried out. At present, the development of microalgae resources is mainly carried out by photobioreactors. [0004] Photobioreactors include: cylindrical photobioreactor, cuboid photobioreactor, cubic photobioreactor, spherical crown ph...

AI Technical Summary

Problems solved by technology

However, due to the small scale, limited volume, small specific surface area, large floor area, insufficient gas exchange and low utilization rate of these reactors, the temperature, pH value, dissolved oxygen, medium concentration, light intensity, etc. The parameters are difficult to control in real time, and cannot provide suitable conditions for the growth and metabolism of microalgae
