[0016] The side wall of the culture reactor A is provided with a medium feed port and a feed port, and the bottom of the culture reactor A is provided with a sampling ...

specific Embodiment approach 2

[0022] Specific embodiment 2: This embodiment is a further description of the integrated culture device for oleaginous microalgae described in specific embodiment 1. In this embodiment, it also includes: microalgae harvester 7; microalgae harvesting The device 7 is used to collect the microalgae sample flowing out from the other end of the No. 2 electric valve 3-2.

specific Embodiment approach 3

[0023] Specific embodiment three: This embodiment is a further description of the integrated culture device for oil-producing microalgae described in specific embodiment two. In this embodiment, it also includes: a visible light source; the light source is used to provide microalgae visible light.

[0024] Turn on the visible light source to let the light pass through the transparent reactor B, so that the microalgae seeds can fully contact with the light and carry out photosynthesis. Compared with reacting under natural light, adding a visible light source in this embodiment can make the reaction more sufficient, and it is suitable for conditions with weak natural light or no light.

Abstract

The invention relates to an integrated culture device of oleaginous microalgae, belonging to the field of preparation of oleaginous microalgae. The integrated culture device of oleaginous microalgae disclosed by the invention aims to solve the problems of being high in energy consumption and easy to cause secondary pollution in the existing sectional culture. The integrated culture manner is adopted in the integrated culture device of oleaginous microalgae disclosed by the invention; high-density culture and oil content enrichment culture are combined together to culture synchronously; the process of moving microalgae between the two culture stages is avoided, therefore, the secondary pollution problem is solved; circulating hot water can be sufficiently utilized; the energy consumption in the culture process is reduced; the culture efficiency is increased; simultaneously, the time can also be effectively utilized; and each culture period of microalgae is shortened within 48-72 h. The integrated culture device of oleaginous microalgae disclosed by the invention is applied to culturing microalgae.

Description

technical field [0001] The invention belongs to the field of oil-producing microalgae preparation. Background technique [0002] Bioenergy is the key to solving energy problems. It is a representative of clean energy, not only has excellent recyclability, but also is environmentally friendly, green and clean, and it is an area of ​​great concern to the energy departments of various countries in the early 21st century. The cultivation of oleaginous microalgae can be simply divided into two stages. The first is high-density culture, the number of algae at this stage is accumulated, and the second is the enrichment of oil content after high-density culture. [0003] The existing cultivation method adopts segmented cultivation. First, high-density culture is carried out to accumulate the number of oleaginous microalgae to reach a higher density, and then the higher density oleaginous microalgae are transferred to the next stage, that is, oil content enrichment culture. Howev...
