Easily expanded gas-liquid mixing and mass transfer flat plate photobioreactor device

Abstract

The invention relates to an easily expanded gas-liquid mixing and mass transfer flat plate photobioreactor device, which is characterized by comprising a plurality of flat plate reactors which are connected in parallel, wherein each flat plate reactor comprises a reactor shell, flow guiding plates, a gas-liquid mixing system and an exhaust pipe; each reactor shell is of a rectangular plate-type structure and the surface of the reactor shell is made from a light-transmitting material; a water pumping port and two air outlets are formed in the top surface of each reactor; the water pumping port is connected to a water pumping pipeline and the air outlets are connected to an elbow pipe; a draining port and a liquid inlet are formed in the bottom surface of each reactor; the pair of the flow guiding plates are arranged in a perpendicular mode; the flow guiding plates are as wide as the reactor and the height of the flow guiding plates is 3 / 4 of the height of the reactor; the flow guiding plates are made from tempered glass or organic glass; and the entire reactor is divided into an ascending area in middle and two descending areas at two sides. The flat plate photobioreactor device provided by the invention has the beneficial effect that by combining a jet device and a static mixer, each gas-liquid mixer serves as a special mixer for mixing gas and liquid.

Description

technical field [0001] The invention relates to an easy-to-expand photobiological plate reactor, in particular to a photobiological plate reactor with high-efficiency gas-liquid mixing and mass transfer. Background technique [0002] The photobiological plate reactor has a large specific surface area, simple structure, and low cost, and is suitable for the engineering application of microalgae carbon fixation in thermal power plants. At present, most of the flat plate reactors are in the experimental research stage, and most of them are small and medium-sized devices. Due to the simple scale-up, the structural strength of the reactor will be reduced, the circulation rate of the algae liquid will be slowed down, the gas-liquid mass transfer effect will be reduced, and the disturbance will be weakened, resulting in the generation of The failure of oxygen to be discharged in time directly leads to a significant drop in the efficiency of microalgae cultivation, and the structure...
