Abstract

The application provides a tube for a microalgae photobioreactor. A projection is arranged on the inner wall surface of the tube, and the projection axially and spirally rotates and extends along the tube. Under the same condition, algae fluid can be automatically stirred into a turbulent state in the flowing process, and sedimentation and algae stacking are avoided. Lower flow rate is allowed in the tube through the structure, the energy consumption of system circulating delivery is reduced, the stay time of the algae fluid in the tube can be prolonged through the low flow rate, the time for the contact between the tube and light is prolonged, and the growth efficiency is improved.

Description

technical field [0001] The application relates to the field of photobioreactors for cultivating photosynthetic microorganisms or photosynthetic plant tissue cells, in particular to a tube with spiral protrusions on the inner wall. Background technique [0002] Microalgae cells are rich in sugar, protein, fat, vitamins, pigments, bioactive 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, and the inner wall of the tube used for cultivating algae is a smooth circular inner surface, and the algae liquid will stratify and settle during the flow process. The contact time greatly reduces the growth efficiency. Contents of the invention [0004] The invention solves the problem that the algae liquid in the pipe will sett...
