Raceway pond microalgae reactor for realizing frequency-division uniform distribution of sunlight by utilizing nano light guide plates

Abstract

The invention discloses a raceway pond microalgae reactor for realizing frequency-division uniform distribution of sunlight by utilizing nano light guide plates. The reactor comprises a raceway pond middle baffle wall arranged in the reactor. The reactor is characterized in that a plurality of light channels are formed in a flow channel around the raceway pond middle baffle wall in the reactor; each light channel is formed by stacking a sunlight condenser, a band-pass filter and a nano light guide plate, wherein the band-pass filter is arranged between the sunlight condenser and the nano light guide plate; the nano light guide plate is longitudinally inserted in the raceway pond microalgae reactor, and the front surface of the nano light guide plate corresponds to the raceway pond middle baffle wall; a reflective film is arranged at each of the bottom of the nano light guide plate and the upper parts of the front and back surfaces of the nano light guide plate; and a plurality of aerator pipes are dispersedly arranged between every two adjacent channels in the bottom of the reactor. According to the raceway pond microalgae reactor, light energy is provided for the growth of microalgae by utilizing emergent light of the nano light guide plates; and the reactor can be widely applied to the fields of biology, environmental protection, energy and the like.

Description

technical field [0001] The invention relates to a photobioreactor, in particular to a runway pond microalgae reactor which uses a nanometer light guide plate to realize frequency division and uniform distribution of sunlight. Background technique [0002] Microalgae is a type of single-celled algae that can achieve photoautotrophy. Because of its high photosynthetic rate, fast growth rate, strong environmental adaptability, and wide range of biomass uses, it can be used to efficiently fix carbon dioxide and alleviate global warming. At the same time, microalgae biomass can be used to produce biofuels to alleviate the shortage of fossil energy, and is considered to be the biomass source of the third generation of biofuels. In addition, microalgae biomass can also be used to produce high value-added products such as pharmaceuticals, cosmetics, and health care products, which has good economic benefits. [0003] Photobioreactor is a device for microalgae cultivation, which pro...

Problems solved by technology

[0004] However, due to the large depth of the microalgae cell suspension in the photobioreactor of the runway pool, and the light intensity attenuation is severe when the light propagates in the microalgae cell suspension, it attenuates exponentially.

Therefore, the penetration ability of sunlight in the microalgae cell suspension is limited, and its penetration depth is generally only 0-4cm, so that a large part of the microalgae cells in the photobioreactor in the runway pool cannot receive light, and thus make the Low biomass production of microalgae in the raceway pond photobioreactor
