Harvesting device, harvesting method and photobiological culture system of photobioreactor

Abstract

The invention discloses a harvesting device for a bioreactor, a harvesting method and a photo-biological culture system. The harvesting device is used for harvesting algae cultured in the photo-biological reactor. The photo-biological reactor comprises a plurality of plate-type culture units, each culture unit extends along the horizontal direction, the culture units are arranged in a sandwich manner in the vertical direction, and a culture space for accommodating a culture solution is formed in the upper surface of each culture unit; and a side opening is formed in the side face between each two adjacent culture units. The harvesting device comprises an inhaler and a collection container, wherein the inhaler comprises an inhaling hole and a connecting hole which are communicated with each other, the inhaling hole can be connected to the side opening, and the connecting hole is communicated with the collection container; the collection container is communicated with the inhaling hole through the connecting hole and can generate negative pressure, and algae solutions on the culture units can be harvested at the inhaling hole and stored in the collection container. The harvesting device can be used for effectively reducing energy consumption for algae solution collection, has a high harvesting speed and a low loss rate, and is suitable for industrial application.

Description

technical field

[0001] The present invention generally relates to a photobiological cultivation system, in particular to a photobioreactor harvesting device, a harvesting method and a photobiological cultivation system. Background technique

[0002] Microalgae are a kind of autotrophic plants widely distributed in land and ocean, rich in nutrients and high in photosynthetic utilization. The polysaccharides, proteins, pigments, etc. produced by cell metabolism make them useful in the fields of food, medicine, genetic engineering, and liquid fuels. Very good development prospects.

[0003] The mass cultivation of microalgae has a history of several decades. The current industrialized microalgae cultivation is a liquid immersion type, that is, a large amount of culture medium is used as the medium for the growth of microalgae, and the algae are submerged in the culture medium for cultivation. Submerged culture mainly includes open culture tank and closed photobioreactor (photo...
