Microalgae population culture device and microalgae culture method

Abstract

The present invention relates to the field of microalgae culture, and discloses a microalgae population culture device and a microalgae culture method. The microalgae population culture device comprises: a cylinder body of a cylindrical hollow structure with an opening at the top end; a cylinder cover; a driving structure; a combined rod which comprises a rod body, a first inflation channel and a first light bar; a central column which comprises a column body, a second inflation channel and a second light bar; a compression fan which is arranged on the column body and communicates with the first inflation channel and the second inflation channel; a power source which is arranged on the column body and electrically connected with the driving structure, the first light bar and the second light bar. Through the arrangement of the technical scheme, the light distribution is uniform; the aeration range is wide and uniform, and the vortex-shaped water flow state and floating bubbles can prevent microalgae cells from settling and reduce wall attachment and bottom sinking in cooperation with the stirring effect; other foreign microalgae or organisms are prevented from entering the culture system, and the structure is compact and cleaning is convenient.

Description

technical field [0001] The invention relates to the field of microalgae cultivation, in particular to a microalgae population cultivation device and a microalgae cultivation method. Background technique [0002] Microalgae can effectively use light energy, CO2 and inorganic salts to synthesize proteins, fats, carbohydrates and a variety of high value-added bioactive substances, and can produce health food, food additives, feed and other chemicals through microalgae cultivation. Especially in recent years with the development of bioenergy technology, some oily microalgae can be used in saline-alkali land, desert, Marine aquaculture has the great advantage of not competing for land and people for food, and can use carbon dioxide in factory exhaust gas as a carbon source. Countries all over the world have taken it as a very important way to solve the shortage of biomass energy resources. way, and invest huge funds and research strength in research and technology development. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a microalgae population cultivation device and a microalgae cultivation method, which can solve the problems in the prior art that the light intensity is not suitable, a large number of microalgae adhere to the wall and sink to the bottom, are easily polluted by the outside world, and the structure is not compact Difficult to clean
