选煤厂粉尘在线监测与治理技术

Dust On-line Monitoring and Governance Technology of Coal Preparation Plant

针对煤矿选煤厂降尘效果不理想,无法对现场粉尘浓度进行实时检测并有效降尘的情况,提出了应用粉尘在线监测与气水两路喷雾自动降尘装置,对现场粉尘浓度进行自动分析,当粉尘浓度超过一定限值后进行自动喷雾降尘。该系统在皮带机机尾处试用后降尘效果较为明显,大大降低了现场粉尘浓度,工作环境得到了显著改善。

For the situation that dust-settling effect is not ideal, onsite dust concentration is not real-timely detected and dust-settling is not effective, using dust on-line monitoring and gas and water spray automatic dust- settling device is put forward, onsite dust concentration is automaticly analyzed, when the dust concentration exceeds a certain limit, automatic spray for dust-settling is carried on. dust-settling effect of the system installed in the tail of belt conveyor is more obvious, onsite dust concentration is greatly reduced, the work environment is significantly improved.
