The windproof net′s effect on direct air-cooled unit

Although it is well known that windproof net is very useful to control the form and diffusion of coal dust,the windproof net has not been widely applied to large-scaled coal ports.

The purpose,methods and contents of the model test on windproof net for the coal storage yard is described and the test result is analyzed.

Numerical simulation of windbreak net's dustproof effect in coal container yard;

The flow field of a large storage yard with windbreak was investigated in the wind tunnel under three dominant wind directions.

The windbreak is barely used in harbor engineering of China,and there are not much design experiences and the standard calculation method hasn t come to agreement.

The static and dynamic response analyses on wind excitation of the windbreak structure around the coal store yard of Qinhuangdao Port are conducted.

By studying dynamic characteristics of windbreak structure in Qinhuangdao,as well as the dynamic response characteristics of windbreak structure under pulsating wind pressure,the structural safety problem of windbreak in Qinhuangdao has been solved.

By using the large-area blower, this paper tests the wind-proof effect of butterfly-type wind-proof and dust-control net under natural condition, and based on the test results, points out that the butterfly-like wind-proof and dust-control net, which can get the ideal wind-proof and dust-control effect, can make 5 degree wind speed drop to 1 and 12 degree to 3.
