Reaction casing for a photosynthetic reactor and associated photosynthetic reactor

摘要

Reaction casing (1) for a photosynthetic reactor suitable for cultivating photosynthetic microorganisms, in particular algae, said reaction casing (1) being designed for both floating on an expanse of water and defining a path for a gas/liquid culture medium to flow in two phases between a first and a second opening (11, 12) of said casing. The casing comprises, on the one hand, an upper membrane (31) and a lower membrane (32) made at least partially of a flexible material, hermetically sealed and transparent to light radiation, said membranes being hermetically connected to one another by connecting lines (41, 42) defining inflatable cells (33, 34) and, on the other hand, connection elbows (35, 36) joining said cells in pairs to define the course of flow in a generally sinuous form, one of the cells (33) being fluidly linked to the first opening and another cell (34) being fluidly linked to the second opening (12). The present invention is applicable in the field of photosynthetic microorganism cultivation, in particular algae cultivation.
