Abstract
The invention discloses an aeration control system for a photobioreactor. The aeration control system comprises an illuminance sensor, a turbidity sensor, an air supply device, and a controller; the illuminance sensor is used for measuring light intensity around the photobioreactor; the turbidity sensor is used for measuring the concentration of light organisms in the photobioreactor; and the air supply device is used for supplying aeration air to the photobioreactor; and the controller adjusts the supplied air flow of the air supply device according to the light intensity which is measured by the illuminance sensor and the concentration of the light organisms, which is measured by the turbidity sensor. Therefore, the aeration quantity can be adjusted according to the light intensity and the concentration of algae liquid. When the light is intense, the aeration quantity is large, and stirring velocity is increased; when the light is weak, the aeration quantity is small, and the stirring velocity is reduced; meanwhile, when the concentration of the algae liquid is high, the aeration quantity is increased; when the concentration is low, the aeration quantity is reduced, so that the optimum aeration stirring intensity for growth of microalgae is kept. Therefore, the yield of the microalgae is increased, energy consumption of the aeration is reduced, and production cost is reduced.
Description
technical field [0001] The invention relates to an aeration control system for a photobioreactor. Background technique [0002] Microalgae can effectively use light energy, carbon dioxide, water, and inorganic salts to synthesize proteins, fats, carbohydrates, and high-value-added bioactive substances. Algae have higher growth potential than higher plants because of their extremely high light and nutrient utilization efficiency. , so the cultivation of microalgae has received extensive attention. [0003] At present, the large-scale industrial production of microalgae mostly adopts the open pool type. This production mode has problems such as unstable production, easy to be polluted, uneven light received by microalgae, low utilization rate of light energy, and low cultivation efficiency. Therefore, the development of microalgae production and microalgae biotechnology industry is restricted. In recent years, scholars at home and abroad have conducted a series of research o...
