为预测镇江大港港区散货码头矿砂在堆放和装卸中的粉尘污染情况,在风洞中进行了模拟试验。本文介绍了风洞试验情况,并得出了铁矿砂堆垛的起动风速,矿砂堆垛起尘量与风速、矿砂含水量之间的关系,堆垛起尘后降尘扩散情况以及矿砂装卸起尘量与风速的关系。这些成果对于有关的港口建设与管理、钢铁公司的矿砂堆场及装卸中的防粉尘污染都有实用价值。 In order to predict the dust pollution during the piling, loading and unloading of bulk cargo terminals in Zhenjiang Dagang Port, a simulation test was carried out in a wind tunnel. In this paper, the wind tunnel test is introduced, and the relationship between wind speed, sand dust accumulation, wind speed and water content of iron ore sand, the dust dispersion after dust accumulation and ore loading and unloading The relationship between the amount of dust and wind speed. These achievements have practical value for the related port construction and management, the iron ore yard of steel companies and dust pollution prevention during loading and unloading.
