摘要:

介绍了新庄选煤厂在煤炭洗选生产过程中煤尘产生源,分析了煤炭产品在生产、运输、储装、发运环节中产生煤尘的原因,并针对目前生产系统的实际情况,通过布置除尘器、封闭物料溜槽和运输皮带、在煤尘点和储煤场洒水、降低设备出料口风压、加装排风装置、增加在转载点和入料口物料防破碎装置等有效措施来降低煤尘浓度,结果表明,通过治理和改造,社会效益和经济效益显著,各环节煤尘浓度控制在10 mg/ m3以下,同时每年可为厂增加经济效益约106万元。

Abstract:

Introduced dust generation source in the production process of coal washing in Xinzhuang Coal Preparation Plant, analyzed forming reasons of the coal dust in production, transportation, storage, shipping links, according to the present production system, reduced coal dust concentration by precipitators arranged, material chute and transport belts enclosed, watered in coal dust and coal storage yard, cut down wind pressure in equipment outlet, exhaust devices installed, anti-crushing device increased on the transfer point and the feeding inlet, results show that has remarkable economic and social benefits through the management and transformation, various links of coal dust concentration is controlled in 10 mg / m3 below, generate annual profits about 1.06 million yuan.
