摘  要：
为进一步降低生物质锅炉烟气排放污染,针对生物质锅炉烟气排放特点,设计了一种具有除尘、脱硫、余热利用功能的多效烟气净化装置,研究了该装置的工艺设计、系统计算,考察了该套装置的连续烟气净化性能。生物质锅炉多效烟气净化装置经过连续性运行,整体运行稳定,烟气温度、烟气SO_2含量、烟尘含量、SO_2去除率、烟尘去除率等工艺参数和运行指标均较为平稳。出口烟气温度控制在(62±3)℃范围内,平均出口烟气SO_2质量浓度为4.2 mg/m~3,SO_2去除率达到70.6%。平均出口烟尘质量浓度为4.6 mg/m~3,烟尘去除率达到90.57%,具有较好的运行稳定性和较高的除尘、脱硫效率。

摘  要：
Boiler flue gas has become an important source of atmospheric pollution,biomass fuel boiler was applied widely. However,the biomass boiler flue gas purification technology and equipment was shortage. In order to further reduce the pollution of biomass flue gas emissions,a multiple flue gas purification device with dust removal,desulphurization and waste heat utilization was developed. Flue gas dust removal using cyclone separation and atomized spray method,flue gas desulfurization using alkaline water washing and atomized spray desulphurization,waste heat utilization using high,low pressure multistage flue gas heat transfer utilization. The structure design, system calculation and running performance of this biomass flue gas purification device were also studied. The study showed that the flue gas purification device showed a stable operation characteristic and high purification efficiency,which gas temperature,SO_2 content, dust content, SO_2 removal rate, dust removal rate and other operating parameters were stable during the continuous operation. The result showed that the outlet gas temperature was( 62 ± 3) ℃,SO_2 concentration 4. 2 mg/m~3,and dust content of 4. 6 mg/m~3. The mean SO_2 and dust removal rate add up to 70. 6% and 90. 57% respectively. The multiple flue gas purification device had good operating stability and high dust removal,desulfurization efficiency.
