And its wind-proof dust-suppression method.
Background technique
With the gradually prominent and national continuous attention for environmental issue of environmental problem, dust pollution is as one
Serious pollution sources have obtained the highest attention of relevant department.China's economy is grown rapidly, the cargo transporting amount of the bulk cargos such as coal
It is continuously increased, outdoor coal yard, stock ground etc. easily generate fugitive dust in operation operation process, cause serious pollution.2013, state
Business institute issues《About the notice for printing and distributing prevention and control of air pollution action plan》, it is desirable that large-scale dump, stock ground must realize closing
Storage or construction wind-proof dust-suppression facility.Wind-proof dust-suppression net can effectively control the hand that scattered rickyard plays dirt and diffusion as one kind
Section, has been widely applied among Practical Project.
When wind passes through wind-proof dust-suppression net, can occur separating and adhering to two kinds of phenomenons after wall, form upper and lower interference gas
Stream, wind-proof dust-suppression net can reduce the wind speed for carrying out wind, and loss carrys out the kinetic energy of wind to greatest extent, reduce the turbulivity of wind, thus
