摘要:

为解决燃煤电厂输煤系统煤粉尘外泄问题,通过对比不同方案,采用包括曲线落煤管、全封闭除尘导料槽、脉冲布袋除尘器、湿式除尘器等防抑尘设备和技术,提出输煤系统降尘防尘的优化方案,形成涵盖煤炭燃料“翻、堆、取、运”全作业过程的粉尘防控体系,并以随州发电工程为例实施应用。研究结果表明:该方法可有效减少煤炭燃料转储运各环节中煤尘溢出的情况,能够实现作业环境无尘化和燃料运输清洁化,为有效控制输煤系统作业时产生的煤粉尘污染提供了一种可行的防尘技术。

Abstract:

To solve the problem of coal dust leakage from the coal handling system of coal-fired power plants, by comparing different solutions, dust prevention and control equipment and technologies were adopted including curved coal fallout pipe, fully enclosed dust-removing guide chute, pulsed bag dust collector, and wet dust collector. The optimized solution for dust reduction and prevention of the coal handling system was put forward. The dust prevention and control system covering the whole operation process of coal fuel ″turning, stacking, picking, and transporting″ was formed and was applied in Suizhou Power Generation Project. The results of the study show that the method effectively reduces the spillage of coal dust in all aspects of coal fuel transfer and basically realizes a dust-free operating environment and clean fuel transport. It provides a feasible dust prevention technology for controlling the coal dust pollution produced during the operation of the coal handling system.

Key words: coal-fired power plant, coal handling system, dust, coal dump, comprehensive management
