The current prevention measures for industrial dust have fence/porous fence, chemical stabilizer, watering, etc. This study mainly discusses a new type of prevention measures: indoorized storage piles. This study mainly refers to the calculation of industrial wind erosion dust method in USEPA's AP42 and use ANSYS Fluent model to calculate the emission and the efficiency for indoorized storage piles. By simulating different conditions, the emission is 588.84(t/year) for case of no control measure; the emission is 132.3(t/year) and the efficiency is 77.5% for case of porous fence; the emission is 34.93(t/year) and the efficiency is 94.1% for case of indoorized storage piles; the emission is 82.09(t/year) and the efficiency is 86.1% for watering; the emission is 10.9(t/year) and the efficiency is 98.1% for case of porous fence with watering; the emission is 3.8(t/year) and the efficiency is 99.4% for case of indoorized storage piles with watering.
