Description

Device for mixing and conveying fresh water microalgae culture air and carbon dioxide Technical Field The utility model relates to the technical field of mechanical and electromechanical integration, in particular to a device for mixing and conveying air and carbon dioxide for fresh water microalgae cultivation. Background The growth of the fresh water microalgae needs to comprehensively consider various factors such as illumination, temperature, nutrient salt, pH value, a culture system and the like, different types and environments need to be pertinently optimized, the pH value of artificial culture needs to be ensured to be stable through environmental regulation so as to promote the growth, the stable pH value is greatly related to the amount of introduced carbon dioxide, the influence of the carbon dioxide concentration on the growth of the fresh water microalgae is greatly related to several aspects, firstly, carbon dioxide gas can be used as a carbon source for the growth of the fresh water microalgae, a proper amount of carbon dioxide can promote the growth of the fresh water microalgae, on the other hand, excessive carbon dioxide gas introduced into the algae liquid is combined with water to generate carbonic acid, the pH of the algae liquid is rapidly reduced, the introduced carbon dioxide content in the air is generally about 1% -5%, so that the excessive carbon dioxide concentration in the air can inhibit the growth of the fresh water microalgae, and the microalgae can die in a large area in severe cases. At present, in the prior art, the existence of fresh water microalgae is maintained by adopting the content of carbon dioxide naturally contained in air, and no special device for detecting the pH value is used in the microalgae liquid, so that the content of carbon dioxide in the microalgae liquid cannot be accurately controlled, and basically, whether carbon dioxide is added into the microalgae liquid is judged by the experience of an operator. The carbon dioxide inlet pipe and the air inlet pipe are respectively arranged, and in general, the carbon dioxide inlet pipe is closed and can be opened only when carbon dioxide is required to be introduced into the microalgae liquid. This mode of operation has a large impact on microalgae production.
