Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Fig. 1 is the structural representation of photobioreactor of the present invention, comprises base 9, transparent bioreactor 3, light source 1, air filter 6, three-way regulating valve 7 and air compressor 8, and transparent bioreactor is housed on the base 3. The ventilation port at the upper end of the transparent bioreactor is sealed with the outside world and equipped with a ventilation tube. 4. The distance between the lower port of the ventilation tube and the bottom of the transparent bioreactor is 3-5 cm, so that the sterile air that passes through has a better Stirring action. The ventilation pipe 4 is connected with the air filter 6, the three-way regulating valve 7 and the air compressor 8 in turn. When connected, the two ports of the three-way regulating valve are respectively connected with the air compressor and the air ...

Abstract

This invention discloses a photo bioreactor, which is a small-scale photo bioreactor with such advantages as simple production, low cost and high microalgae culture efficiency. A transparent bioreactor is mounted on a base. The air vent at the upper part of the transparent bioreactor is sealed, and equipped with an air pipe. The air pipe is connected with air filter, three-way regulative valve and air compressor in sequence. An exhaust mouth is set at the side of the transparent bioreactor, which is sealed and equipped with an air pipe. A bacteria-filtration membrane or filter medium is set at the bottom end of the air pipe. Multiple light sources surround the transparent bioreactor on the base. The photo bioreactor realizes the preparation of compressed sterile air by using the air compressor and the filter, and the adjustment of the sterile air flux into the reactor by using the three-way regulative valve. The photo bioreactor can thus realize the adjustment of dissolved CO2 concentration in microalgae culture system and the stirring degree, and ensure uniform nutrition distribution in the system. The photo bioreactor has such advantages as simple production.

Description

technical field [0001] The invention relates to a photobioreactor device for cultivating microalgae. Background technique [0002] Photobioreactor is a key technology for high-density cultivation of microalgae. Photobioreactors for microalgae cultivation mainly include mechanically stirred photobioreactors and tubular photobioreactors. At present, in small-scale microalgae culture containers, mechanically agitated photobioreactors are generally used. The stirring blade of this reactor has great shear damage to the cells, the light source utilization rate is not high, and the microalgae culture density is low. And its price is generally more expensive, increasing the burden of the experiment. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies in the prior art and provide a small-scale photobioreactor with simple manufacture, low price and high microalgae cultivation efficiency. [0004] The present invention realizes through ...
