Flat-plate photobioreactor device system

Abstract

The invention relates to a flat-plate photobioreactor device system. The flat-plate photobioreactor device system comprises a photobioreactor body, an aeration system, an algae liquid circulation system and a spray system, wherein the photobioreactor body comprises a reactor shell, a spray area and reaction areas; n stages of reaction areas are available, n is greater than 1, the n stages of reaction areas are partitioned by inner partition boards, and space is reserved between the inner partition boards and the bottom of the reactor shell, so that algae liquid can enter each reaction area from the spray area; flow guide plates are arranged in the reaction areas along the flowing direction of the algae liquid, and are positioned in the central positions of the reaction areas; space is reserved between the flow guide plates of the n stages of reaction areas and the top of the reactor shell. The flat-plate photobioreactor device system has the beneficial effects that the large-scale application of the microalgae carbon fixation technology can be realized, the problems that the traditional stirring mixing method is poor in mixing effect, and the shear force generated by stirring can severely damage the cellular structure of the microalgae are solved, the sufficient mixing of CO2 and the algae liquid in the photobioreactor is guaranteed, and the CO2 mass transfer rate is improved.

Description

technical field [0001] The invention relates to a flat-plate photobioreactor device and system, in particular to microalgae-fixed CO 2 flat-panel photobioreactor device system. Background technique [0002] Global warming caused by the "greenhouse effect" is a major environmental problem facing mankind in the 21st century. CO 2 The contribution to the greenhouse effect accounts for about 50% of all greenhouse gases, while CO 2 More than 70% of China's emissions come from the combustion of fossil fuels such as coal and oil, so controlling the CO released by coal-fired power plants 2 Very important. [0003] To address CO emissions from coal-fired power plants 2 For emission issues, microalgae carbon sequestration technology is one of the most promising technologies. The growth of microalgae has many requirements on the culture environment, such as temperature, light and photoperiod, CO 2 Concentration, etc. have an impact on it. Photobioreactor is the main engineering e...
