Device for breeding phototropic micro-organisms

摘要

Apparatus comprising interconnected: a process water storage tank (1), a transition tank (2), an exchanger (3) formed of: a pasteurization, a recuperation and a cooling sections, an ice water aggregate (5), a heating water tank (6), a photobioreactor (7), a reproduction and heating pure cultures tank (8), a prepared nutrients heating tank (9), a carbon dioxide gas tank (10), a mixing pump (11), a centrifuge (12), and a biomass storage tank (13), creating a functional installation, characterized in that, the photobioreactor (7) in its spacious closed tank (14) has at least one light element (19) and this element is formed of a cylindrical transparent tube (20) of ring-shaped, circular cross section inside which a column (22) with LED light-emitting diodes (25) embedded on its walls is placed. The tube (20) is sealed from the bottom with a lid (21) and its top edges project above the photobioreactor's tank (14) closing cover (17). The column (22) is formed of a pass-through tube, and includes a fan placed on the top. On the outer side of the tube (20) and parallel to its axis and opposing to each other vertical collectors (26) powered by a mixing pump (11) are located, in these collectors hydraulic nozzles (27) are mounted, with it's outlets facing the outer surface of the tube (20).;Apparatus applies the light-emitting diodes LED (25) emitting light at wavelengths 450 - 470 nm - blue light, 650 - 670 nm - orange light and 700 - 740 nm - red light. The inner wall of the photobioreactor's tank (14) constitutes reflective surface (30) of the light emitted and the walls itself constitute a heating jacket (15) with the outer insulation layer (16).;Mixing nozzles (31) are mounted in the sidewall of the tank (14) equipped with a turbidity sensor (47).
