TECHNICAL FIELD
[0001] The utility model relates to the field of environmental protection and energy utilization technology, especially to tail gas drive power generation control ion transmembrane transport's efficient biological carbon fixation treatment device. BACKGROUND
[0002] With the rapid development of global economy, the massive emission of industrial tail gas has become one of the important factors leading to climate change and energy crisis. According to the International Energy Agency (IEA) 2020 report, global carbon dioxide (CO2) emissions continue to rise, posing a serious threat to the environment and ecosystem. Therefore, reducing CO2 emissions and improving energy efficiency have become important issues facing the world.
[0003] Microalgae, as a biological resource with high CO2 utilization capacity, have been widely concerned and regarded as one of the important ways to solve the above problems due to their rapid growth, easy cultivation and high ecological and economic benefits. Microalgae can convert CO2 into organic matter through photosynthesis, while producing oxygen, which is of great significance to alleviate the greenhouse effect and improve energy efficiency. However, industrial carbon-containing tail gas not only has large flux, but also has high CO2 concentration, which directly used for microalgae cultivation not only causes CO2 secondary escape, but also often leads to limited growth or even death of microalgae.
[0004] Currently, some technologies have attempted to convert CO2 in industrial tail gas to provide a suitable growth environment for microalgae. For example, by converting CO2 in solution into carbonate, electric repulsion, and screening through ion membrane, a suitable culture environment for microalgae growth is formed. This kind of technology reduces the dissipation of high concentration CO2 escape to some extent, but still has some problems.
[0005] Specifically, most existing technologies are still in the laboratory stage, lacking mature devices to effectively combine tail gas conversion with microalgae symbiotic devices. These technologies often have low efficiency, high cost, and complex equipment when dealing with large-scale industrial tail gas. For example, in [Reference 1: A novel system integrating electrolysis and ionic membranes (EIMs) enables artificial carbon concentration and alleviation of metal cation stress in microalgae cultivation, author: Hou Yuyong, journal name: Green Chemistry, publication year: 2023, volume: 25. Issue number: 18, page number: 7273-82], although a CO2 conversion device based on electronic repulsion for transmembrane screening is disclosed, the device has not yet been practically connected with large-scale industrial tail gas treatment.
