DEVICE FOR CULTIVATING MICROORGANISM USING SOLAR LIGHT ENERGY

摘要

PURPOSE:To enable the effective use of solar light energy and the cultivation of microorganism by photosynthesis, by loading a ship, car, etc. with a closed type device for cultivating microorganism to be provided with light energy of collected solar light. CONSTITUTION:Light energy obtained by a device for collecting solar light using a lens array is sent to the light radiator 1 for the Chlorella culture tank 10 by the light conductive cable 20. The culture tank 10 is closed, microorganisms are recovered by the Chlorella recovery device 11, and a carbon dioxide gas and a medium are fed to it. Photosynthesis is carried out by absorbing water, a very small amount of nutrient source, namely the medium, and the carbon dioxide gas, etc. introduced into the medium, and the microorganisms are propagated by absorbing phosphorus, nitrogen, a very small amount of other metals in the medium. The propagated Chlorella is recovered through the recovery device 11, evolved oxygen is exhausted into the air, the carbon dioxide gas, water, etc. are returned to the culture tank 10. Since the device for cultivating Chlorella is of a closed type, it can be transferred by a car, ship, etc. and cultivation can be carried out effectively.
