摘要

脱硫吸收塔对烟气中的细小粉尘具有一定的脱除效果

但其脱除效率还有待进一步提高。本文采用理论分析和工程实践相结合的方法对脱硫吸收塔协同除尘的效率提升进行了研究。结果表明

通过在脱硫吸收塔内设置导流环和正六边形开孔均流板、优化喷嘴布置、增加液滴凝聚系统可以增加脱硫塔的除尘效率。在陕西某电厂实际应用后

系统除尘效率显著提高

可达到61%以上

能够满足火电厂对粉尘的超低排放要求。

Abstract

The desulfurization absorber has certain removal effect on fine dust in flue gas

but its removal efficiency needs to be further improved. In this paper

theoretical analysis and engineering practice are combined to study the efficiency improvement of desulfurization absorption tower. The research shows that

the dust removal efficiency of the absorber can be increased by several means

such as setting guide ring and hexagonal flow equalizer with holes in the absorber

optimizing the layout of the nozzles

and installing the liquid droplets agglomeration system. Moreover

this method was verified in a power plant in Shaanxi Province. It turns out that the dust removal efficiency reached 61%

which met the requirements of ultra-low emission.
