摘要
针对化工行业VOCs治理难题,本研究以某涂料厂废气处理工程为例,探讨商用纳米催化材料的催化氧化工艺应用。基于废气特征(苯系物质量浓度800~1200 mg/m^(3),风量15000 m^(3)/h)及排放限值(非甲烷总烃质量浓度≤50 mg/m^(3)),选用市售纳米钯基催化剂构建处理系统。通过参数优化确定最佳反应温度(280~320℃),VOCs去除率稳定在95%以上。长期运行表明,催化剂活性衰减速率0.04%/d,系统压降<800 Pa,运行成本较传统技术降低45%。配套多级过滤与安全联锁设计,有效防控颗粒逃逸风险。结果表明,商用纳米材料经工艺适配可实现高效低耗治理,为中小企业提供可推广的技术方案。
In response to the difficult problem of VOCs control in the chemical industry,this study takes the waste gas treatment project of a certain paint factory as an example to explore the application of commercial nano catalytic materials in catalytic oxidation process.Based on the characteristics of exhaust gas(mass concentration of benzene derivatives 800~1200 mg/m^(3),air volume 15000 m^(3)/h)and emission limits(mass concentration of non methane total hydrocarbons≤50 mg/m^(3)),a commercially available nano palladium based catalyst is selected to construct a treatment system.By optimizing parameters,the optimal reaction temperature(280~320℃)was determined,and the VOCs removal rate remained stable at over 95%.Long term operation has shown that the catalyst activity decay rate is 0.04%/d,the system pressure drop is less than 800 Pa,and the operating cost is reduced by 45%compared to traditional technology.Equipped with multi-level filtering and safety interlock design,it can effectively prevent and control the risk of particle escape.The results indicate that commercial nanomaterials can achieve efficient and low consumption management through process adaptation,providing scalable technical solutions for small and medium-sized enterprises.
