Abstract
The utility model discloses a wind-restraining wall, which comprises a base, a holding frame and a wind-restraining wallface. The utility model is characterized in that the wall body has a certain height, and the wallface is set with a plurality of ventholes, which can loose the kinetic energy of the inflow in maximum limit, so as to avoid the obvious eddy flow of the inflow, and reduce the turbulivity of the wind to reach the purpose of reducing the dust emission, so that the utility model is simple in structure, and is economic and practical with good effect of wind retaining. The utility model can decide the height of the wind retaining wall as per the height of the stockpile to reach the optimal dust suppression effect, and accordingly to prevent the pollution to the surrounding air environment by the dust emission of the open bulk material yard.
Description
Technical field
The utility model belongs to the environmental protection field, is specifically related to a kind of brattice that presses down at open-air bulk cargo stockyard dust pollution improvement.
Background technology
Countries such as Korea S, Japan, Australia are just studied the technology of carrying out dust pollution improvement by the inhibition wind speed nineties, China's research in this regard is later, at present dust pollution is administered main employing watering spray system, covered with green net, but these measures all fail fundamentally to solve the dust pollution problem.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, and a kind of simple in structure, economical and practical, effective brattice that presses down is provided.
For achieving the above object, the utility model adopts following solution: a kind of brattice that presses down, and comprise basis, bracing frame, press down the brattice metope, it is characterized in that: body of wall has certain altitude, have some gravity vents on metope, the cross sectional shape of body of wall is a curved configuration.
The above-mentioned brattice that presses down is characterized in that: described gravity vent is one or more in square hole, circular hole, oblong aperture, slotted hole, tri-angle-holed, the diamond hole.
But above-mentioned brattice is characterized in that: the area of described gravity vent is for pressing down 20%～50% of brattice face area, and the body of wall height is 3～35 meters.
The utility model is arranged on enterprise open-air bulk cargo stockyard, and set-up mode is totally-enclosed or semiclosed, presses down the brattice height and decides according to the stockyard height.
Depositing dust principle of the present utility model is to press down the wind speed that brattice can effectively reduce incoming flow wind, change a part of incoming flow wind by pressing down the wind direction behind the brattice, lose the kinetic energy of incoming flow wind to greatest extent, avoid the obvious eddy current of incoming flow wind, reduce the turbulivity of wind and reach the purpose that has reduced dirt.
Compared with prior art, the utlity model has following advantage:
1, because the utility model is to have some gravity vents in pressing down on the brattice body of certain altitude, can lose the kinetic energy of incoming flow wind to greatest extent, avoid the obvious eddy current of incoming flow wind, reduce the turbulivity of wind and reach the purpose that has reduced dirt.So the utility model is simple in structure, economical and practical, it is effective to press down wind.
2, the utility model height that can determine to press down brattice according to the height of stockpile to be reaching best anti-dust effect, thereby can effectively prevent and treat the pollution of airborne dust to the ambient atmosphere environment.
Description of drawings
Fig. 1, structural representation of the present utility model.
Fig. 2, along the sectional drawing of A-A line among Fig. 1.
Among the figure: 1, press down brattice metope 2, bracing frame 3, delthyrium
4, circular hole 5, rectangular opening 6, concrete foundation
The specific embodiment
Embodiment 1: certain power plant's coal yard, be shaped as rectangle, and 967 meters of girths, dump is high 12 meters, and cardinal wind is a northwester throughout the year, and the residential quarter is adjoined in its southern side, and the coal yard airborne dust pollutes the residential quarter.The brattice that presses down as depicted in figs. 1 and 2 is set around coal yard, pressing down brattice metope 1 is fixed on the bracing frame 2, its bottom is provided with concrete foundation 6, and have gravity vents such as some delthyriums 3, circular hole 4, rectangular opening 5 pressing down on the brattice metope 1, its percent opening is 31%, pressing down the brattice cross section is shaped form, and it is high 15 meters to press down brattice.
When wind from outside when pressing down brattice, reduce the wind speed of the wind comes from, make the kinetic energy of wind be subjected to very big decay, the dust suppression rate can reach more than 70%.
Embodiment 2: certain iron company's coal yard is shaped as square, 11 meters of dump height, girth is 860 meters, and Office Area and living area are adjoined in west side and southern side, summer the cardinal wind southeaster, winter cardinal wind northwester, airborne dust causes severe contamination to Office Area and living area.Be provided with around coal yard and press down brattice (as shown in Figure 1 and Figure 2), it is high 15 meters to press down brattice, and percent opening is 34%, and all the other structures are with embodiment 1.
When wind from outside when pressing down brattice, reduce the wind speed of the wind comes from, make the kinetic energy of wind be subjected to very big decay, the dust suppression rate can reach more than 75%.
The utility model presses down the percent opening of brattice body of wall and the effect that the body of wall height determines to press down wind, can Situation according to meteorological condition and stock ground is selected suitable height and percent opening.
Claims (3)
1, a kind of brattice that presses down comprises basis, bracing frame, presses down the brattice metope, and it is characterized in that: body of wall has certain altitude, has some gravity vents on metope, and the cross sectional shape of body of wall is a curved configuration.
2, the brattice that presses down according to claim 1 is characterized in that: described gravity vent is one or more in square hole, circular hole, oblong aperture, slotted hole, tri-angle-holed, the diamond hole.
3, the brattice that presses down according to claim 1 and 2, it is characterized in that: the area of described gravity vent is for pressing down 20%～50% of brattice face area, and the body of wall height is 3～35 meters.
