燃烧后烟气的脱硫除尘技术

Desulfurization and dust removal technology for post-combustion flue gas

为了满足环境保护的要求,燃烧后烟气要实现达标排放,必须对其中的二氧化硫及灰份进行治理。本文重点介绍了燃烧后烟气脱硫除尘技术中石灰法脱硫除尘的原理、工艺流程、装备及实际应用效果。石灰法脱硫具有投资少、脱硫效率高、运行成本低等优点。

In order to meet the requirements of environmental protection, a flue gas after combustion should reach the discharge standards, so the sulfur dioxide and ash must be treated. This paper introduces the principle of lime method after combustion, flue gas desulfurization and dust removal technology of dust removal and desulfuriza- tion process, equipment and the actual application effect. Lime desulfurization with less investment, high efficiency, low - cost operation.
