Cleaning device for photobioreactor, and photobioreactor

Abstract

The invention discloses a cleaning device for a photobioreactor, and the photobioreactor. The photobioreactor comprises a pipeline. The cleaning device is used for cleaning the pipeline, and comprises an inner ring body and an outer traction device, wherein the inner ring body is positioned in the pipeline; the inner ring body comprises a magnetic ring body and a cleaning structure layer arranged out of the magnetic ring body; the cleaning structure layer can be matched with and fit to the inner wall of the pipeline, and the inner wall of the pipeline can be cleaned in a friction way; the outer traction device is positioned out of the pipeline by corresponding to the inner ring body; the outer traction device and the magnetic ring body can generate magnetic forces which mutually act; the outer traction device can drive the inner ring body to move in the pipeline. Through the action force of the outer traction device, the inner ring body can be controlled to move and rub with the pipeline wall, and an interval period of movement, movement speed and the friction strength of different positions can be regulated.

Description

technical field [0001] The invention relates to an algae cultivation system, in particular to a cleaning device for a photobioreactor and a photobioreactor for preventing algae growing in a transparent tube from accumulating on the tube wall. Background technique [0002] Microalgae are a kind of autotrophic plants widely distributed on land and ocean, rich in nutrients and high in photosynthetic utilization. The polysaccharides, proteins, pigments, etc. produced by cell metabolism make them widely used in food, medicine, genetic engineering, liquid fuel and other fields. It has a good development prospect. [0003] However, there are not a large number of ready-made microalgae resources that can be directly collected and processed in nature. To develop microalgae resources needed for the development of human society, it is first necessary to cultivate and produce microalgae raw materials on a large scale. At present, the large-scale artificial cultivation of microalgae ma...

AI Technical Summary

Problems solved by technology

The existing cleaning process of photobioreactors for large-scale algae cultivation can only be carried out after harvesting, but this method cannot maintain the light transmittance of the tube wall during the "algae cultivation process", resulting in the inability to improve the efficiency of natural light utilization

And setting aside a special time period to clean the equipment will reduce the effective use time of the photobioreactor, and the maximum cultivation efficiency of the photobioreactor cannot be obtained.
