Description

Technical Field

[0002] Microalgae cultivation is a crucial technology for bioenergy development, carbon sequestration, and the production of high-value-added products. The performance of its core equipment, the photobioreactor, directly impacts cultivation efficiency. Currently, mainstream technologies exhibit two typical structures: First, the transparent tubular reactor, constructed with spirally arranged glass or polycarbonate tubing. While offering good light transmittance, it suffers from significant drawbacks: low space utilization due to tubular installation; high flow resistance from tubular bends necessitates the installation of circulation pumps, leading to excessive energy consumption; cleaning algae deposits from the tubing walls requires specialized equipment, resulting in difficult operation and high maintenance costs; and the use of irregularly shaped tubing molds increases manufacturing costs and leads to high losses. Second, the planar stainless steel reactor, employing a welded stainless steel frame with a transparent top plate. While facilitating large-scale deployment, it suffers from the following problems: severe light shading by the stainless steel frame, resulting in light loss; large footprint, hindering photosynthesis and reproduction of microalgae; rapid heat conduction through the metal frame causing significant temperature fluctuations in the culture medium, hindering temperature control; individual manufacturing costs increase exponentially with size, insufficient modularity hinders large-scale application; and it is difficult to disassemble and clean.
