中文摘要:
      以福建省某化工危险废物处理工程为例,研究固态危废焚烧处置设施的技术性能。工程采用高温涡流燃烧+二燃室+水冷除尘器+急冷塔+干式吸附+布袋除尘+喷淋吸附+雾水分离工艺,设计处理量为100 kg/h。研究结果表明:在测试工况下,二燃室温度为(1 149.6±13.4)℃;烟气在炉膛的平均停留时间为(5.35±0.12)s,燃烧效率为99.97%;萘与CCl4的焚毁去除率分别为99.996%与99.991%,热灼减率为3.3%;焚烧设施的技术性能达到《危险废物焚烧污染控制标准》(GB 18484—2020)的要求;二噁英的排放值为0.007 6 ngTEQ/m3,HF和CO的排放值分别为1.21 mg/m3和72.8 mg/m3,烟气排放达标。
英文摘要:
      Taking a chemical hazardous waste treatment project in Fujian as an example, the technical performances of solid hazardous waste incineration disposal facilities were investigated. High temperature eddy combustion + secondary combustion chamber + water cooled dust removal + quench tower + dry adsorption + bag filter + spray adsorption + mist separation were adopted in the project, with the designed processing capacity of 100 kg/h. The results showed that under the test conditions, the temperature of the secondary combustion chamber was (1 149.6±13.4)℃, the average residence time of flue gas in the furnace was (5.35±0.12)s, the combustion efficiency was 99.97%,the incineration removal rates of naphthalene and carbon tetrachloride were 99.996% and 99.991% respectively, and the thermal reduction rate was 3.3%. The technical performances of the incineration facilities met the requirements of “Standards for pollution control on hazardous waste incineration”(GB 18484—2020). The emissions of Dioxin, hydrogen fluoride and carbon monoxide were 0.007 6 ngTEQ/m3、1.21 mg/m3and 72.8 mg/m3,respectively. Flue gas met the emission standards.
