[0002] The pipe-type photobioreactor is a common microalgae cultivation device. Its main structure is a spiral structure composed of straight pipes, curved pipes and pipe connectors. It has the characteristics of large lighting area and is suitable for large-scale open-air cultivation. When the pipe-type photobioreactor cultivates microalgae in the open air, dust and scale will gradually accumulate on the surface of the reactor pipe, causing the light received by the microalgae in the reactor to weaken, affecting the growth of the microalgae. Therefore, the pipe-type bioreactor needs to be cleaned regularly.

[0003] When cleaning many existing tubular photobioreactors, the inner side of the spiral structure reactor body is difficult to clean. Cleaners are required to hold a flushing tube and insert the flushing tube into the gap between the spiral pipes for flushing. Cleaners are also required to avoid collision between the flushing tube and the reactor pipe to prevent cracks in the reactor pipe due to collision, which makes the cleaning of the tubular photobioreactor inconvenient. Therefore, it is necessary to develop a tubular photobioreactor for microalgae cultivation to solve the above problems. Utility Model Content
