Tube bundle type photobioreactor

Abstract

The invention provides a tube bundle type photobioreactor. The tube bundle type photobioreactor comprises n*m tube bundle assemblies, wherein n tube bundle assemblies are arranged in one direction side by side and are connected in parallel to form a tube bundle assembly group; m tube bundle assembly groups are arranged in one direction side by side and are connected in series to form the tube bundle type photobioreactor; each tube bundle assembly comprises p horizontally placed reaction tubes which are arranged in one direction side by side, the n is larger than or equal to 1, the m is larger than or equal to 2, and the p is larger than or equal to 2. The invention further provides the reaction tube for the tube bundle type photobioreactor.

Description

technical field [0001] The present application generally relates to the field of photobioreactors for cultivating photosynthetic microorganisms or photosynthetic plant tissue cells, and specifically relates to a horizontal tube row photobioreactor for cultivating photosynthetic organisms and the tube row components used therein. Background technique [0002] Microalgae cells are rich in sugar, protein, fat, vitamins, pigments, biologically active substances, and trace elements and other high value-added biological substances, and are becoming an important source of materials in the fields of human food, medicine, dyes, and fine chemicals. Broad application prospects. [0003] The core of the large-scale cultivation of microalgae is the photobioreactor. At present, there are two main methods: open cultivation system and closed cultivation system. [0004] The open culture system was developed earlier and is most commonly used. However, the utilization rate of light energy i...

Problems solved by technology

[0006] However, the tubular photobioreactor, which is an example of a closed photobioreactor system, has its own disadvantages while improving algae bioproductivity.

For example, the tubes of the tubular photobioreactor are connected by flanges, and the distance between the tubes is relatively large, which makes the volume of the photobioreactor used for cultivating the same amount of microalgae larger, while the number of flanges is large and the number of connection points Many, high possibility of leakage

[0007] In addition, there is a serpentine tube photobioreactor, which is mainly made by bending pipes. Since the bending of the tube of rigid material has the minimum bending radius, the photobioreactor with this structure is also a waste of space.
