离子液法烟气脱硫技术和石灰石-石膏法烟气脱硫技术在燃煤电厂应用对比分析

摘要

简单介绍了离子液烟气脱硫技术和石灰石-石膏法烟气脱硫技术.以一台300MW燃煤发电机组的烟气参数为例, 对两种技术从设备材质、技术指标、运行成本和系统投资等方面进行了对比分析.石灰石-石膏法烟气脱硫作为燃煤电厂烟气处理的主流技术应用广泛, 但产生的大量二次污染物给燃煤电厂造成了很大的困扰;离子液循环吸收法作为一种新颖的、高效型、资源型烟气脱硫技术而被广泛关注, 应用前景广阔.%The ionic liquid and limestone-gypsum flue gas desulfurization applied to FGD are introduced in this paper. Taking the flue gas parameters of a 300 MW coal-fired generator unit as an example, the two technologies are compared and analyzed from the equipment material、technical indexes、operating cost and investment. Limestone-gypsum FGD is widely used in coal-fired power plants, but a large number of secondary pollutants produced by this desulfurization system, it has caused great trouble to coal-fired power plants. Ionic liquid FGD is widely concerned as a novel、high desulfurization efficiency、resource-based technology, it has a wide application prospect.
