- the medium supply pipe 92 of the medium supply unit 90 may be provided with a valve for intermittent supply of the medium, the culture of the photobioorganic discharge pipe 101 constituting the optical bioorganic storage unit 110 is cultured
- a control valve 103 may be installed to control the discharge of the completed photobioorganic gas.
- control unit 150 enables continuous production of the photobioorganism, and each sensor, that is, the PH measuring sensor 120 and the dissolved amount measuring sensor 130 for measuring the dissolved amount of oxygen and carbon dioxide. And a system for controlling the system based on a signal of an illuminance measuring sensor 140 and a biomass concentration measuring sensor 145 for measuring illuminance of light irradiated from the surface light source unit 70 to the flat panel bioreactor module. Equipped with a microcomputer.
- the biomass concentration measurement sensor is Opt is preferably used ASD19-N, the dissolved oxygen sensor is preferably used Mettler toledo M300.
- control unit may be further provided with a temperature sensor 151 for measuring the temperature of the photo organisms cultured by the plate-type photobiological culture vessel.
- the plate-type photobioreactor module and the photobiological culture system using the same according to the present invention configured as described above are capable of culturing continuous photobioorganisms.
- a medium including a microalgae for culturing the photobioorganisms is supplied to the culture space 21 of the plate-type photobioreactor 20 through the medium supply unit 90.
- the planar photobiological reaction vessel 20 is irradiated with light using the surface light source unit 80, and the medium for culturing stored in the storage space 21 using the gas supply unit 70. Feed oxygen and carbon dioxide.
- the discharge hole of the gas supply pipe 71 is opened when the pressure is higher than the set pressure, it is possible to prevent the medium for culturing through the gas supply pipe 71 to flow back through the discharge pipe.
- the control unit 150 includes an illuminance sensor 140, a dissolved-quantity sensor 130, a temperature sensor 151, a PH sensor 120 and a biomass concentration measuring sensor ( By optimizing the culture atmosphere by the signal detected from 145) it is possible to maximize the culture efficiency.
- the cultured photobioorganisms are stored in the photobioorganic storage tank through the photobioorganic discharge pipe. This process enables the continuous production of photobioorganisms.
- the plate-type photobioreactor module and the photobiological culture system using the same are irradiated with light from the outside of the plate-type photobioreactor using the surface light source unit, so that heat generated from the lamp module of the light source unit is cultured. It can be prevented from being delivered directly to the photobiological organism in question.
- the photobiological culture system according to the present invention can be irradiated to a flat-type photobiological culture vessel using light irradiated from a lamp such as sunlight and a light emitting diode, so that the degree of freedom of design can be increased, and the light guide plate is used. Irradiation of the photobioreactor can maximize the uniformity of light distribution.
- this photobiological culture system can be easily adjusted in the high concentration culture by microalgae by optimizing the culture conditions of photobiotic organisms, and can increase the spatial efficiency.
