Abstract
The utility model discloses a dust retaining wall, which includes a support frame. The plane of the support frame perpendicular to the ground is the wall. The wall is provided with a plurality of rectangular wind shields with a slope angle. The wind shields comprise a louver window with a louver cross section. The wall is of a certain height. The utility model is a louver-type dust retaining wall comprised of a plurality of wind shields arranged on a support frame with a certain height. When the wind blows dusts to the dust retaining wall, motion energy of the dust particles is reduced, and the particles finally drop onto the ground due to the inertia and the gravity. The utility model is featured with simple structure, economy, practicability and good dust retaining effect. The height of the dust retaining wall can be determined in accordance with height of the material piles to achieve the optimum dust retaining effect and effectively avoid pollution of rising dusts of open coal fields, scattered material piling fields or construction sites to the ambient environment.
Description
Technical field
The utility model belongs to the environmental protection field, is specifically related to a kind of dust break wall at power plant, colliery, harbour, harbour, open-air coal yard or bulk cargo stockyard and building site dust pollution improvement.
Background technology
Countries such as Korea S, Japan, Australia are just studied the dust pollution technology in open-air coal yard and bulk cargo stockyard the nineties, China's research in this regard is later, at present dust pollution is administered and adopt mainly in the open that coal yard, bulk cargo stockyard and building site are provided with the watering spray system, cover, spray the dust suppression coagulating agent 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, dust break wall that dust-break is effective is provided.
For achieving the above object, the utility model adopts following solution: a kind of dust break wall, comprise bracing frame, bracing frame plane perpendicular to the ground is a metope, it is characterized in that: some verge boards that have the angle of slope are set on metope, verge board is a rectangle, and these verge boards are formed louvered, and its cross sectional shape is a louver structure.
Above-mentioned dust break wall is characterized in that: the angle of inclination between described verge board and the metope is 10 °-170 °, and the body of wall height is 3～30 meters.
The utility model is arranged on around power plant, colliery, harbour, harbour, the open-air coal yard of enterprise or bulk cargo stockyard and the building site, and set-up mode is totally-enclosed or semiclosed, and the dust break wall height is decided according to the stockyard height.
Depositing dust principle of the present utility model is to utilize the verge board that has the angle of slope to form windbreak, and grit and verge board are after collision, and grit kinetic energy reduces, and utilizes its inertia and deadweight that grit is landed simultaneously, reaches the purpose of depositing dust.
Compared with prior art, the utlity model has following advantage:
1, because the utility model is to be provided with some verge boards that have the angle of slope on bracing frame, thereby constitute the dust break wall of venetian blind type, when wind blows to dust break wall with grit, grit kinetic energy reduces, utilize its inertia and deadweight that grit is landed simultaneously, so the utility model is simple in structure, economical and practical, dust-break is effective.
2, the utility model height that can determine dust break wall according to the height of stockpile to be reaching best anti-dust effect, thereby can effectively prevent and treat the pollution to the ambient atmosphere environment of open-air coal yard or bulk cargo stockyard and building site airborne dust.
Description of drawings
Fig. 1, be structural representation of the present utility model.
Among the figure: 1, verge board 2, bracing frame
The specific embodiment
Embodiment 1
Certain coke-oven plant's coal yard is shaped as rectangle, 350 meters of girths, and each 120 meters in north and south, each 55 meters of things, dump is high 8 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.Dust break wall (as Fig. 1) is set in the coal yard southern side, and dust break wall is arranged on the bracing frame 2 by some verge boards 1 and constitutes, and verge board 1 is a rectangle, and cross sectional shape is a louvered, and the angle of inclination between verge board 1 and the body of wall is 45 °, and dust break wall is high 11 meters.
When wind from outside when the dust break wall, reduce the wind speed of the wind comes from, make the kinetic energy of wind be subjected to very big decay, grit has strengthened the grit sinking speed after colliding with impeller, reaches the effect of dust-break, helps depositing dust to greatest extent.The dust-break rate can reach more than 70%.
Certain Mechanology Inc.'s boiler room coal yard is shaped as square, and 4 meters of dump height, girth are 240 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.Around coal yard dust break wall (as Fig. 1) is set, verge board 1 is a rectangle, and cross sectional shape is a louvered, and the angle of inclination between verge board 1 and the body of wall is 55 °, and dust break wall is high 6 meters.
The angle of inclination of the utility model blade and body of wall, the ventilative rate of decision body of wall and the angle of the wind comes from direction and blade can be selected suitable angle according to the situation in meteorological condition and stock ground, satisfy certain ventilative rate and require to get final product.
Claims (2)
1, a kind of dust break wall comprises bracing frame, and bracing frame plane perpendicular to the ground is a metope, it is characterized in that: some verge boards that have the angle of slope are set on metope, and verge board is a rectangle, and these verge boards are formed louvered, its cross sectional shape is a louver structure, and body of wall has certain altitude.
2, dust break wall according to claim 1 is characterized in that: the angle of inclination between described verge board and the metope is 10 °-170 °, and the body of wall height is 3～30 meters.
