摘要
火力发电厂输煤系统由于除尘系统工艺布置不科学和设计的不合理性,导致原设计的除尘系统无法满足对现场除尘的要求,致使尘源点设备区域内粉尘污染严重,导致现场作业环境远远超过10mg/Nm3的要求,严重超标的粉尘污染影响安全生产以及危害员工的身心健康。本文对火力发电厂输煤系统粉尘污染的原因进行分析、总结,提出了解决问题的方法,改善现场作业环境,消除安全隐患,保证安全生产,为新建机组设备选型以及在运机组改造工程提供参考。
Owing to the unscientific processing set-up and unreasonable design of dedusting system in coal transfer system of thermal power plant, the dedusting system that designed previously can not meet the need of site dedusting, serious dust pollution has occurred in dust source point equipment area, field work environment has exceed the requirements of 10mg/Nm3, and greatly exceeding dust pollution has influenced safety in production and jeopardized employees＇ health. The paper analyzes and summarizes the causes of dust pollution in coal transfer system of thermal power plant, and puts forward solutions solving the problems, which will improve field work environment, eliminate security risks and ensure safety in production. It is hoped that the paper be of reference for equipment selection of newly constructed set and modification works of transport units.
