摘要：

随着全球气候环境问题不断显现，关于CO₂减排的问题受到社会各界越来越多的关注。其中，以燃烧矿物作为主要能源来源的火电厂是CO₂最大的排放源，减少火电厂CO₂排放对缓解温室效应也就具有重大意义，当前火电厂实现CO₂减排的有效措施为富氧燃烧，研究富氧技术对减少火力发电厂CO₂减排有着重要的实用价值。根据传统的电渗析溶液除湿技术，提出了一种新型的基于电渗析技术直接作用于空气的富氧方法，并根据理论分析发现：在电场强度小于50 kV的情况下提高空气湿度与电场强度能显著增加装置富氧效果。

Abstract:

With the continuous emergence of global climate and environmental issues, the issue of CO₂ emission reduction has attracted more and more attention from all sectors of society. Among them, thermal power plants that use burning minerals as the main energy source are the largest sources of CO₂. Reducing CO₂ emissions from thermal power plants is also of great significance in mitigating the greenhouse effect. Currently, effective measures to achieve CO₂ emission reduction in thermal power plants are oxygen-enriched combustion. Oxygen enrichment technology has important practical value for reducing CO₂ emissions from thermal power plants. In this paper, based on the traditional electro-osmosis solution dehumidification technology, a new type of oxygen enrichment method based on electro-osmosis directly acting on the air is proposed. According to theoretical analysis, it is found that the oxygen enrichment effect of the device can be significant increased by improving the air humidity or electric field strength when the electric field intensity is less than 50 kV.
