Biological microalgae photosynthesis reactor and application method thereof

Abstract

The invention discloses a biological microalgae photosynthesis reactor and an application method thereof. The biological microalgae photosynthesis reactor comprises a microalgae photosynthesis bioreaction system and a reaction tower, wherein the reaction tower and the microalgae photosynthesis bioreaction system are connected through a circulating liquid delivery pipeline; the microalgae photosynthesis bioreaction system is composed of multiple groups of vertical transparent pipelines connected in series; the top of each group of vertical transparent pipelines is provided with an oxygen discharge device for releasing oxygen gas; and the bottom of each group of vertical transparent pipelines is provided with a carbon dioxide injection port for helping cell division acceleration. Thus, Spirulina can be cultured indoors; the discharge of oxygen gas and the injection of carbon dioxide are facilitated; accelerated cell division is satisfied to achieve the purpose of fast growth; and the inside of the pipeline is less prone to pollution. The biological microalgae photosynthesis reactor is novel in design, is a favorable innovation scheme, and has great market popularization prospects.

Description

technical field [0001] The cultivation device for spirulina of the present invention particularly relates to a biological microalgae photosynthetic reactor and a use method thereof. Background technique [0002] Spirulina is a class of lower plants with simple and primitive cell structure and no chromatophores in the cells. It is the earliest photosynthetic organism on the earth, and its pigments are distributed in the pigmented area outside the protoplast. Spirulina contains β-carotene, vitamins B1, B2, B5, B6, B11, B12, C, E, and a variety of essential trace elements calcium, magnesium, sodium, potassium, phosphorus, iodine, selenium, iron, copper , zinc, etc., as well as γ-linolenic acid and polysaccharides, each of which has special physiological functions, can enhance the body's immunity, inhibit the carcinogenic effect of some carcinogens, and have good effects on reproduction, cardiovascular, respiratory, digestive and nervous systems . The cell wall of Spirulina is...

Problems solved by technology

Due to the influence of water source, temperature, light, and nutrient solution on natural conditions, weather, seasons, and regions, the annual production effective time is less than 240 days in the south and 180-150 days in the north of the Yangtze River. The growth of Spirulina requires nitrogen, phosphorus, and potassium. , also needs a large amount of CO2, and needs to grow in an alkaline environment with a pH value less than 11, so it is necessary to add a large amount of baking soda (NaHCO3) in the breeding pond. Due to the long-term addition of baking soda, the pH value in the breeding pond will increase, affecting The growth of spirulina will affect the output of spirulina. If the acid is used directly to neutralize the spirulina, it will kill the spirulina. Moreover, the temperature of the spirulina is not easy to control when it grows, the light energy cannot be effectively used, and the carbon dioxide cannot be obtained in time The supply of spirulina has great defects in the actual cultivation process, and there are also closed pipelines to produce spirulina, such as Chinese patent No. 03128138.9, patent name: a photosynthetic bioreactor system for industrial production of microalgae, consisting of three-dimensional double-row Flat spiral pipeline and unique U-shaped connecting elbow, double reaction tower, infusion pump with zero shear force, carbon dioxide gas injection device, artificial lighting device, cold and heat exchanger, etc., although this reactor is also equipped with carbon dioxide Gas injection device, but it cannot be injected into each transparent tube separately, the injection amount of carbon dioxide is not easy to control, which brings inconvenience to the actual production of spirulina, and oxygen can only be discharged by a separate oxygen exhaust device, which is easy to cause pollution to the pipeline , the microorganisms are destroyed, and the lighting cannot be flexibly controlled. The reaction tower can only be connected to one reaction device, which increases the production cost, and the production efficiency is very low. There are deficiencies and cannot meet the needs of rapid social development.
