Abstract: An integrated system of speedy pitch melt technology,separate installation of dust plenum and centralized bag filtration of dustwas combined with multi-tube electrostatic dust filtration in baking furnace to control dust contamination in the production workshop of a carbon factory. Experimental results showed that this project could enhance production workshop dust cleaning efficiency to 83.9%~93.2%. After purification,the concentration of dust emission was 20.0 mg/m3,the concentration of asphalt gas emission was 14.2 mg/m3,and the concentration of benzopyrene emission was 0.054×10-3mg/m3. All of the above pollutants complied with the national pollution emission standards. This project found a feasible way of dust and asphalt gas control in a small sized carbon factory.

摘要: 通过炭素厂车间粉尘和沥青烟治理工程实例,阐述了在沥青熔化、粉碎、混捏、压型、焙烧工序采用快速沥青熔化技术、分散安装集气罩与集中袋式除尘系统一体化、焙烧炉多管静电除尘系统相结合的污染物控制设计方案。结果表明:该工程能使车间作业场所空气中粉尘的净化效率达到83.9%~93.2%,大大降低了车间空气粉尘浓度。焙烧炉净化处理后烟尘排放质量浓度为20.0 mg/m3,沥青烟排放质量浓度为14.2 mg/m3,苯并[a]芘排放质量浓度为0.054×10-3 mg/m3,所有污染物均达到排放标准。为小型炭素厂粉尘及沥青烟的综合治理探索了一条切实可行的途径。
