Embodiment Construction

[0033] Such as figure 1 with figure 2 As shown, the modular microalgae culture of the present invention. It includes five modules of an algae seed expander 8, a photobioreactor 4, a medium addition system, a gas delivery system, and an algae liquid delivery and supernatant return system. The photobioreactor 4 is installed on the bracket 13, and the bracket 13 has an angle adjuster for adjusting the inclination angle of the photobioreactor 4. The included angle between the photobioreactor 4 and the horizontal plane is 50-70°. The algal seed expander 8 is installed on the backlight side of the photoreactor 4 . All modules are pre-manufactured and assembled on site, and the substances between the modules are transported through pipe fittings during operation. Microalgae that can be cultured heterotrophically and have rapid biology can all be cultivated in the present invention, such as Chlorella, Scenedesmus tetrasaurus, Scenedesmus obliquus, Chrysophytes, Phaeodactylum tric...

Abstract

A modular microalgae culture system with a rapid algal species expanding culture device comprises the algal species expanding culture device, a photobioreactor, a culture medium adding system, a gas delivery system and an algae solution delivery and supernate backflow system, wherein the algal species expanding culture device is connected with the culture medium adding system, the photobioreactor is respectively connected with the algal species expanding culture device, the culture medium adding system, the gas delivery system and the algae solution delivery and supernate backflow system and is inclined, and the algal species expanding culture device is installed on the backlight side of the photobioreactor. The system is in modular design and convenient to install and adjust, all modules are manufactured in advance and assembled on site, substances among the modules are delivered through pipes in operation, installation, maintenance and management difficulty is greatly reduced, the number of element modules can be adjusted according to working conditions at any time, production is maintained under the optimal working condition, and microalgae yield can be greatly improved.

Description

technical field [0001] The invention relates to a culture system for realizing large-scale high-density and high-yield culture of microalgae. The invention belongs to the technical field of microalgae bioengineering. Background technique [0002] Microalgae is a kind of organism with rapid growth and strong environmental adaptability. Various biochemical substances contained in its biomass, such as oil, protein, carbohydrate and pigment, have high economic value and have great development prospects. Especially in recent years, microalgae have been considered as one of the most promising raw materials for the production of biofuels. [0003] Photoautotrophic cultivation in photobioreactors is the main mode of microalgae cultivation. When large-scale cultivation is carried out, a large number of algae species are required. Traditionally, the production of algae species is achieved by microalgae under photoautotrophic conditions by means of step-by-step expansion cultivation...
