Embodiment 1

[0019] Picture 1-1 , 1-2 and figure 2 It is a schematic diagram of the simulation of the case when the windproof net is applied. The material pile in the figure is a trapezoidal volume, the bottom size is 51×154 (m×m), the top size is 10×113 (m×m), and the height is 17m. The setting parameters of the windproof net in this implementation case are: the length of the mesh is 154m, and the length is expressed as L3+L3+L4+L3+L3, which is 1 time of the material pile; the total height of the mesh is 22m, and the height is expressed as L1+ L1+l2 is 1.3 times the height of the material pile; the distance between the windproof net and the bottom of the material pile is 17m, which is 1 time the height of the material pile. Case analysis Peripheral area: length x width x height is 714 x 308 x 119 (m x m x m). Among them, 714=306+357+51(m), in order to better study the flow field area and reduce the influence of the boundary on the flow field, the windward side is selected to be 6 time...

Abstract

The invention discloses a windproof net. The windproof net comprises a net sheet, the net sheet is arranged in front of a material stack windward side, and is of an inverted concave structure, the distance between the arranged position of the net sheet and the edge of the bottom of a material stack is 1-1.5 fold of the height of the material stack, the total height of the net sheet is 1-15 fold of the height of the material stack, the length of the net sheet is 1-1.5 fold of the overall height of the material stack, the opening height of the inverted concave structure is 1 / 2-1 / 3 of the height of the net sheet, and the opening length is 1 / 2-3 / 5 the total length of the net sheet. By the adoption of the windproof net, not only is a good dust resisting effect guaranteed, but also building material consumption is drastically saved.

Description

technical field [0001] The invention relates to a windproof net, in particular to a windproof net used in an open storage yard. Background technique [0002] With the rapid expansion of coal production capacity, coal piles in coal storage yards are wind-eroded and dusty, forming an open dust source in the open air, often causing the concentrations of sensitive indicators such as PM2.5 and PM10 to exceed the standard by several times or even dozens of times in the atmospheric environment around the coal yard. Seriously affect the health of stockyard staff and surrounding residents. In order to effectively control this kind of pollution, it is very necessary to conduct a systematic study on the law of wind erosion and dust generation of coal piles. [0003] The windproof net is a kind of porous barrier, which is generally set around the solid bulk cargo yard. The windproof mesh has a certain porosity, which can improve the wind field and turbulent flow structure of the incom...
