干散货码头防风抑尘措施下堆场静态起尘量的计算研究

Calculation Method of Wind Erosion Dust Source Intensity in a Yard of Dry Bulk Terminal Under the Wind Dust Suppression Measures

研究了《港口建设项目环境影响评价规范》(JTS105-1—2011)推荐的堆场静态起尘量计算公式中考虑堆场围护设施情况下的源强计算,研究结果表明:堆场设置防风网,再结合洒水及多堆堆垛可降低堆场的风速,静态起尘抑尘效率可达98%;堆场设置条形仓,再结合堆场洒水及多堆堆垛间风速的降低,静态起尘抑尘效率可达99%以上;筒仓本身无粉尘外溢问题,起尘量几乎为0。

In this paper, the calculation of wind erosion dust source under the wind dust suppression measures using the recommended formula by 《Specifications for Environmental Impact Assessment of Port Engineering 》(JTS 105-1—2011) were discussed. The results show that yard set the dust screen, combining between pile of stacking yard sprinkler and wind speed decreased, the dust suppression efficiency can reach 98%. Yard set bar, combining with pile of stacking yard sprinkler and wind speed is reduced, the dust suppression efficiency can reach above 99%. Silo doesn't have dust spillover problem, the quantity of dust is almost zero.
