Problems solved by technology

Although the research and manufacture of the above-mentioned various types of photosynthetic bioreactors have different characteristics and advantages in terms of light and nutrient utilization in microalgae cultivation and production, so far they can only be used in laboratories and small, It can be used in pilot production, but it is far from being extended to the industrial production of microalgae.
The main obstacles hindering the application of microalgae photosynthetic bioreactors to industrial production, first of all, the above-mentioned various types of photosynthetic bioreactors are complicated in technical operation, and the investment cost is too high to produce large water bodies; the most d

Abstract

A photosynthesizing bioreactor system for industrial culturing microlgae is composed of dual lines of 3D spiral pipeline with unique U-shaped joint elbow, dual reaction towers including oxygen exhausting tower and regulating tower, liquid delivering pump with zero shear force, CO2 filler, artificial lighting unit and cold (or heat) exchanger. Its advantages are less possessed ground area, high output rate, low energy consumption, and low pollution.

Description

technical field [0001] The invention relates to an industrialized production system for cultivating microalgae, in particular to a photosynthetic bioreactor system for microalgae with closed pipelines. Background technique [0002] Microalgae is a new type of protein resource that has been extensively researched and developed around the world since the 20th century. Microalgae contain high levels of protein, amino acids, vitamins, unsaturated fatty acids, polysaccharides and minerals and other nutrients needed by the human body. From the 1990s to the present, the annual output of my country's microalgae industry, such as spirulina raw powder, has exceeded 1,000 tons. Since the beginning of the 21st century, people have paid great attention to the natural astaxanthin from Haematococcus, which is newly discovered by biological scientists and has high health value. The astaxanthin 3S-3'S contained in this algae, Astaxanthin, is the most exciting new product in the microalgae ...
