Production apparatus for culturing tiny alga and production method

Abstract

This invention relates to a production apparatus for culturing microalgae. The production apparatus comprises more than one transparent tubular culture reactor units aligned in parallel or alternately parallel. The reactor units are fixed on the base by flanges to constitute the production apparatus. A static mixer, a luminescent device and an electromagnetic vibrator are set at the central axis of each reactor unit. CO2 micro-nozzles are set on the central hollow tube of the static mixer, the diversion blade and the bottom of the reactor unit. The production apparatus has such advantages as low investment, easy operation, special structure, adequate utilization of sunlight, and continuous production, can be widely used in microalgae production.

Description

[0001] technology field. [0002] The invention relates to the field of microalgae cultivation engineering, in particular to a production device for cultivating microalgae and a production method thereof. Background technique [0003] Microalgae have been growing in fresh water, sea water or salty lake water since ancient times. In particular, it is well known that Spirulina was discovered in the Lake Chad area in the 1960s and has developed rapidly, because the microalgae is rich in protein and nutrients. , has become a treasure house of concentrated nutrition, and is recommended by the United Nations Food and Agriculture Organization (FAO) as the most ideal and perfect food in the 21st century. Countries all over the world are competing to produce it. At present, the output of countries in the world is close to 10,000 tons. [0004] With the rapid development of industrial production in various countries in the world, the continuous increase of energy consumption and the det...

Problems solved by technology

[0005] At present, the production method of microalgae (such as spirulina, etc.) cultivated in the world is still produced in an open-air large pond production system. Although the production is simple, the investment is low, and the production management technology content is low, there are many defects in this production method. For example, it is prone to biological pollution, that is, pollution from water sources, the atmosphere, the environment, operations, etc., and is severely restricted by climatic conditions, which will bring extremely adverse effects on the quality and stable production of microalgae production, especially in areas with little light and rainy areas and Areas with severe winter seasons cannot produce normally throughout the year, which directly limits the cultivation and development of microalgae

Since the 1980s, microalgae production developers (spirulina) and production engineering experts from all over the world have developed a variety of closed cultivation microalgae (such as spirulina) devices and Method, such as pipeline structure photobioreactor (Torzi110 et al., 1993) and CN1475558A disclose the reactor system of microalgae (spirulina), adopt the double-tower structure of artificial light cultivation, these devices are mainly used for producing food-grade spirulina , large investment, high energy consumption, high cost, difficult long-term industrialized production, as yet no report on the cultivation device and production method containing oil-rich microalgae
