Embodiment 1

[0025] Microalgae (represented by Chlorella) were cultivated in a 20L specific spectrum airlift photobioreactor.

[0026] (1) First place the entire culture tank in a sterilizer for high-temperature sterilization, then place the inner light source in the closed tube of the inner light source, insert each sensor into its socket and connect it to the display device, and connect the gas distribution device and the air inlet , and then place the entire culture tank in the outer light source bracket.

[0027] (2) Close the sampling port. The culture solution containing algae species is injected into the culture tank through the feeding port, and added to the set effective volume scale line.

[0028] (3) After feeding, close the feeding port. Turn on the display devices of the pH, carbon dioxide concentration, and temperature sensors, and record the current values ​​of each parameter.

[0029] (4) Turn on the air compressor pump and the cylinder of carbon dioxide. Set a certain ...

Abstract

The invention belongs to the microalgae-culturing photobioreactor field and particularly relates to a special spectrum airlift photobioreactor for culturing microalgae. The invention solves the problems of the existing photobioreactor such as low utilization rate of light energy, uneven heat transfer, uneven gas-liquid mixture and low CO2 fixing efficiency. The photobioreactor uses a gas distributor to distribute gas and a heat exchanger using condensed water or hot water for temperature control; the internal / external light source adopts a fluorescent lamp with a specific wavelength, the range of wavelength is any wavelength from infrared to near ultraviolet; the top cover and base of a culture tank are made of stainless steel; the base consists of the gas distributor and the heat exchanger; and a guide cylinder which is a transparent glass cylinder is formed in the tank to divide the tank to an ascending area and a descending area. The invention is characterized by simple structure, special-wavelength illumination, uniform gas-liquid mixing, even heat transfer and the like and is suitable for the culture of laboratory microalgae; and all influencing factors are monitored online, the yield can be increased, and the culture period can be shortened.

Description

technical field [0001] The invention belongs to the field of photobioreactors for cultivating microalgae, in particular to a specific spectrum airlift photobioreactor. Background technique [0002] Microalgae is a class of biological resources with great application value, and many active substances come from microalgae. Using photobioreactors to artificially cultivate microalgae is an important way to solve the problem of large-scale cultivation of microalgae. [0003] At present, there are mainly three types of closed photobioreactors for cultivating microalgae, namely stirred tank type, bubble column or airlift type and pipeline type photobioreactor. Pipeline-enclosed photobioreactors are generally formed by bending transparent hard materials with small diameters into different shapes and connecting them. In such pipe-closed photobioreactors, due to the use of small pipe diameters (25-50mm ), although it has a larger ratio of illuminated surface area to volume, which ca...
