摘要
目的:探讨采用组合式除尘技术降低石油焦输送系统粉尘的有效性。方法:设计了组合式除尘装置,并检测除尘效果。结果:转运站总尘时间加权平均浓度(C_(TWA))从3. 414~6. 144mg/m~3下降至1. 38~2. 79 mg/m~3,可降低31. 2%~77. 5%。结论:组合式除尘技术可将粉尘浓度降低至国家职业卫生标准范围内。
Acombinatorial dust removal device was designed and its effectivenessin the removal of dust in petroleum coke conveying system was tested. The total dust time weighted allowable average concentration (C_(TWA)) inthe transfer station decreased from 3. 414 ~6. 144 mg/m~3 to 1. 38 ~ 2. 79 mg/m~3,with a 31. 2% ~77. 5% dedust efficiency. The results showed that the combinatorial dedust technology could reduce the dust concentration to a level below the requirements of national occupational health standards.
