Photoreactor for efficient photosynthetic cultivation of spirulina

Abstract

The invention discloses a photoreactor for efficient photosynthetic cultivation of spirulina. The photoreactor comprises support feet, a barrel and a barrel cover. The barrel is of tubular structure having an upward opening; the support feet are arranged at the lower periphery of the barrel through mounting pads; connection wing plates are connected to the periphery of the open end of the barrel and are integrated to the open end of the barrel; the open end of the barrel is provided with the barrel cover via a connection flange; the barrel cover is in convex type and is internally provided with an overflow weir; one side of the cover is provided with an overflow port. The photoreactor herein is convenient to maintain and wash at the premise that spirulina cultivation quality is guaranteed;therefore, it is effectively avoided that non-uniform distribution of nutrients in algae easily leads to non-uniform lighting for algae in deep and shallow tiers of the photoreactor, which causes optical damage and optical hunger.

Description

technical field [0001] The invention relates to the related technical field of microalgae cultivation, in particular to a photoreactor for high-efficiency photosynthetic cultivation of spirulina. Background technique [0002] Spirulina is characterized by high protein content, low fat and cellulose content, and a wide variety of vitamins. It is the food with the highest content of vitamin B12 and β-carotene. In addition, it is also the most absorbable food in all foods. It is also found that it contains algae protein with anti-cancer and anti-cancer effects, as well as other large amounts of mineral elements and biologically active substances that improve the body's immunity; under the condition of normal nutrition and temperature, light becomes An important factor affecting the growth of spirulina is that the light source for outdoor cultivation is mainly the sun; in the experiment, a cool white light source is generally used, and the light intensity required for growth and...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of high-efficiency photosynthetic cultivation spirulina photoreactor, aims to improve the spirulina cultivation photoreactor in the prior art with simple structure and single mode of use, and then it is easy to cause the spirulina nutrient substance in the reactor The distribution is uneven, and it is easy to cause light damage and light starvation caused by uneven light exposure of deep and shallow algae in the reactor, thereby reducing the cultivation quality of spirulina and most of the light reactors for bolt algae in the prior art are fixed Structure, the fixed structure is not easy to clean and repair, and it is easy to cause the growth of bacterial impurities, which reduces the accuracy of the spirulina cultivation experiment
