Abstract

A microalgae culture system is disclosed. The system includes a microalgae pretreatment pool, a gas liquid mixer, a heat exchanger, a carbon dioxide conveying pipe, a microalgae solution conveying pipe, an aeration device, a bioreactor and a microalgae solution collecting pool. The microalgae pretreatment pool, the gas liquid mixer, the gas liquid mixer, the heat exchanger, the microalgae solution conveying pipe, the aeration device, the bioreactor and the microalgae solution collecting pool are connected in order. The bioreactor is separately connected to the carbon dioxide conveying pipe and the microalgae solution conveying pipe. A microalgae solution pH electrode and a carbon dioxide detector for measuring the carbon dioxide concentration are disposed in the gas liquid mixer. The bottom of the bioreactor is connected to the aeration device through the carbon dioxide conveying pipe. The gas liquid mixer is connected to the heat exchanger. A culture liquid is disposed in the bioreactor. The culture system is simple in structure and high in culture efficiency, and is capable of reducing energy consumption, reducing microalgae settlement and wall adhesion, and increasing the collection rate of the microalgae.

Description

technical field [0001] This field relates to the technical field of microalgae, in particular to a microalgae culture system. Background technique [0002] With the rapid growth of the global economy, the rapid consumption of fossil energy, and the greenhouse effect caused by carbon dioxide emissions has become a major threat to human sustainable development, seeking new energy and reducing carbon dioxide emissions has become a hot issue of concern to all mankind. After years of exploration, scientists have discovered that microalgae is one of the ultimate solutions to the above problems. It can be used to produce different forms of biofuels, such as methane, biodiesel, aviation fuel, hydrogen and even bioethanol. On the other hand, the cultivation of microalgae fixes carbon dioxide through the photosynthesis of microalgae, and converts gaseous carbon into bio-organic carbon. Microalgae energy is a clean energy source with "zero" carbon dioxide emissions. [0003] EM bacter...
