超重力法锅炉烟气同时除尘脱硫脱硝
Simultaneous removal of dust, SO2, and NOx from flue gas in a rotating packed bed
摘要
Abstract
Dust,SO2 and NOx generated in the process of boiler combustion has caused great harm to the environment and human body.With the enhancement of people's environmental awareness,the requirement of the flue gas purification become increasingly stringent.This article presents the side-stream test research on the simultaneous removal of dust,SO2and NOx from flue gas by using O3 as oxidant and NaOH solution as absorbent in a rotating packed bed.The effects of different operation conditions on removal rate of dust,SO2 and NOx were investigated.The dust removal rate,desulfurization efficiency and denitration efficiency can reach 98.3％,98.4％ and 68.7％ respectively under the optimum operation conditions of a rotation speed of 1000 r/min,a gas/liquid ratio of 125,a pH of 11 and a O3/NOx molar ratio of 1.1.The treated flue gas can achieve the environmental protection standard.This process with the advantages of low costs,high efficiency,small size and low investment cost exhibits widely application prospect in the purification of flue gas generated from middle or small boilers.关键词
