Abstract
The invention discloses an adjustable photobioreactor for high-density culture of microalgae. The photobioreactor comprises reaction vessels, a light source and an oxygenation device. The reaction vessels are arranged on two sides of the light source, and each reaction vessel is a square transmitting vessel with the upper bottom surface provided with an air vent. The oxygenation device comprises a main ventilation pipe, a branch ventilation pipe, an oxygenation pump and air distributors. One end of the main ventilation pipe is communicated with the oxygenation pump, one end of the branch ventilation pipe is communicated with the main ventilation pipe through a ventilation quantity adjusting valve, the other end of the branch ventilation pipe is connected with the air distributors, and the air distributors are arranged in the reaction vessels through the air vents. The photobioreactor is simple to operate and low in manufacturing cost, and practical operation in links such as inoculation, culture condition adjustment, sampling and cleaning is simple. Physiological induction is performed by adjusting illumination, ventilation quantity and nutrient solution so as to adjust culture density of the microalgae.

The above-mentioned adjustable algae high-density culture bioreactor that declines, it is that described light source comprises the many fluorescent tubes that are set up in parallel, described fluorescent tube is fixed on the framework, and the parallel sided of the exiting surface of described light source and reaction vessel.
The above-mentioned adjustable algae high-density culture bioreactor that declines, it is that described light source is suspended on the support, and per two fluorescent tubes are controlled by a power switch.
The above-mentioned adjustable algae high-density culture bioreactor that declines, it is that described total ventpipe is arranged on the support.
The material of described reaction vessel is transparent material, such as organic glass.Described total ventpipe is pvc pipe or metal tube, and described ventpipe is pvc pipe or rubber hose.
Beneficial effect of the present invention:
The reaction vessel that the present invention adopts transparent material to make places respectively the fully daylighting of light source both sides, boosts productivity, and is provided with a plurality of power switches adjusting light source, the within the specific limits intensity of regulating illumination.
Adopt oxygen increasing pump and total ventpipe and a ventpipe to realize the preparation of pressurization aseptic gas, the corresponding air flow variable valve of each reaction vessel is regulated the air flow that aseptic gas enters reaction vessel, can control meltage, the stirring extent of gas in the microalgae culture system, guarantee that simultaneously the homogeneous of nutritive ingredient distributes.
This reaction system is simple to operate, cost of manufacture is cheap, and the links such as inoculation, culture condition adjusting, sampling, cleaning are easy to actually operating.
This reaction system can effectively be controlled the culture condition of little algae, reduce natural condition to the interference of experiment, can cultivate in indoor placement, cultivate in extensive raceway pond formula, occupy little space, micro algae growth is quick, experimental implementation of high while of output is dexterous oversimplifies, and has realized low-cost large-scale cultivation of little algae.
