煤炭堆场智能水幕系统洒水设计与应用

分析露天煤炭堆场粉尘治理存在的问题,论述开放性堆场洒水抑尘的重要性。研制出一种移动式的堆场智能水幕系统,可以实现大范围行走、大容量储水、自动寻源补水、煤堆表面的定量精准洒水。该系统采用与堆场大型移动单机集成式设计、利用移动单机悬臂建立臂架喷淋系统实现煤垛表面的全覆盖均匀洒水,结合堆场喷枪洒水管网实现上水单元在多个固定取水点自动寻源补水。工程应用结果表明,移动洒水系统大幅度提高了堆场的清洁生产水平,有效抑制堆场粉尘的排放,实现了堆场煤垛表层全季节高效洒补水,为大型露天堆场的煤尘污染治理提供一种新的可靠技术方案。

Design and application of intelligent water curtain system for coal yard

Based on the analysis of the existing problems of dust control in open coal yards,the importance of dust suppression by watering in open coal yards is discussed.A mobile intelligent water curtain system for storage yard has been developed,which can realize large-scale walking,large capacity water storage,automatic source searching and water supplement,quantitative and accurate watering on the surface of coal pile.The system adopts the integrated design with the large-scale mobile single machine of the storage yard,uses the cantilever of the mobile single machine to establish the boom spray system and realize the full coverage and uniform sprinkling on the surface of the coal stack,and combines with the sprinkling pipe network of the spray gun of the storage yard to realize the automatic source searching and water replenishment of the water supply unit at multiple fixed water intake points.The results of engineering application show that the mobile sprinkler system greatly improves the clean production level of the yard,effectively inhibits the dust emission of the yard,and realizes the efficient water sprinkling on the surface of the coal stack at all seasons,which provides a new reliable technical method for the coal dust pollution control of large open storage yard.
