Dust Pollution Mechanism And Control Technology For Feeder Under Coal Storage Bunker

Integrating the comprehensive management and renovation project of dust pollution ofInner Mongolia Datang International Xilinhaote Mining, it deeply researched the reasons ofserious dust pollution of feeder, and conducted a research about dust spread and migration’sregular pattern. In addition, taking a feeder on106belt in the underground passage of CoalHandling System for example, the article applied gas-solid two-phase flow theory, established areasonable numerical simulation model, and conducted calculation of approximate numericalsimulation about law of dissipation and concentration distribution to dust of the feeder, usinglarge-scale numerical simulation software. Then, according to dust characteristics measured dataand law of dust dissipation, we draft reasonable comprehensive management and renovationprogram of dust pollution, conducted a field construction, and achieved good and effectivegovernance results. The dust concentration in workplaces has been reduced to less than10mg/m3, meet national standards. Practice demonstrates that the dust-cleaning scheme is feasibleand effective dust removal method and worth learning and promotion, that sealing using gratedischarge chute and drawing dust using bag filter.
