Problems solved by technology

[0003] At present, the large-scale cultivation of Haematococcus pluvialis mainly adopts racetrack culture ponds using outdoor natural light. The main factors hindering the large-scale production of Haematococcus pluvialls are biological pollution and population growth during the cultivation process of Haematococcus pluvialis. Low density leads to low output per unit area, resulting in high cost
The defects of Haematococcus pluvialis cultivated by pipeline photobioreactor or bioreactor composed of small-scale system are that the pipe wall is easily adhered by algae cells, which leads to the decrease of light transmittance, unstable temperature and difficulty in cleaning during the cultivation period. Only suitable for small-scale production in the laboratory

Abstract

The invention relates to a continuous algae cultivation and reaction system. The continuous algae cultivation and reaction system comprises at least two photobioreactors, a culture liquid tank and analgae seed tank. The two photobioreactors include a first photobioreactor and a second photobioreactor. The algae seed tank is connected with the first photobioreactor through a first pipe, and provides the first photobioreactor with algae liquid containing algae seeds. The culture liquid tank is connected with the first photobioreactor and the second photobioreactor in parallel through a second pipe, and provides nutrients for different algae growth stages. The first photobioreactor is connected with the second photobioreactor through a third pipe. Each photobioreactor comprises a sealed reactor tank. Waterproof LED lamps are arranged in the sealed reactor tanks. Each LED lamp comprises an LED chip, a sealed transparent lampshade, a heat radiating component and an exhaust component.

Description

technical field [0001] The invention belongs to the technical field of algae cultivation equipment, and in particular relates to a continuous algae cultivation reaction system. Background technique [0002] Microalgae is a kind of autotrophic plant with rich nutrition and high photosynthetic utilization. Its biomass contains a variety of biochemical substances, such as polysaccharides, proteins, oils, carbohydrates, pigments and other substances. It is widely distributed on land and in the ocean. , medicine, genetic engineering, liquid fuel and other fields have broad development prospects. Microalgae grow fast and have strong environmental adaptability, so they can be photosynthetically self-cultured in photobioreactors. Haematococcus pluvialis is a single-celled green algae. Under the conditions of nitrogen deficiency, phosphorus or strong light energy, astaxanthin in the cells of Haematococcus pluvialis will accumulate in large quantities. Natural astaxanthin is one of ...
