Coal yard dust screen type:
The forming width of single peak dust-proof screen (monomer) is between 250mm-500mm, the peak height is 50mm-100mm, and the length can be processed within 7.2m. board The thickness is 0.5mm-1.5mm, within the above range, it can be processed according to the customer's requirements.
Double peak dust-proof net (double body)
The molding width is between 400mm-600mm, the peak height is 50mm-100mm, and the length is within 7.2m. The plate thickness is 0.5mm-1.5mm, within the above range, it can be processed according to the customer's requirements.
The forming width of the three peak dust-proof screen (three body) is 810mm - 910mm, the peak height is 75mm, and the length is within 7.2m. The plate thickness 0.5mm-1.5mm can be processed according to the drawing.
The triplet has the advantages that the previous two specifications cannot match. It is easy to install, has high construction efficiency, and has good overall performance and strong wind resistance after installation. It can greatly reduce the construction cost and improve the competitiveness of the construction unit in the market. If the width is not appropriate, the company can make a single and dual dust-proof screen according to your steel structure size for easy combination.
The length of the dust-proof net shall not exceed 7.2m (the longer the net is, the farther the steel structure is, the worse the wind shielding effect will be). The peak height of 7.5cm has better wind protection effect, which is the conclusion drawn by the wind tunnel test of the National Academy of Sciences.
Material of wind and dust suppression wall: high-quality galvanized steel plate, low-carbon steel plate, color steel plate, aluminum and zinc plated steel plate
Surface treatment of wind screen: electrostatic powder spraying technology treatment, high corrosion resistance, slow reaction ability
Use of dust screen:
Dust net is mainly used for wind prevention and dust suppression in coal storage plants of coal mines, coking plants, power plants and other enterprises; Port, wharf coal storage plant and various stockyards; Dust suppression in various open-air material yards of steel, building materials, cement and other enterprises; Crop windproof, sandy weather dustproof and other harsh environments; * * * Coal storage yard of highway coal gathering station, construction site, road dust, both sides of expressway, etc. The dust suppression effect of single-layer wind and dust suppression wall can reach 65 85%, and that of double-layer wind and dust suppression wall can reach more than 95%.
Features of wind proof and dust suppression wall:
1 Prevent direct sunlight (anti-aging) The surface of the product is sprayed with plastic, which can absorb the ultraviolet rays in the sunlight, reduce the oxidation speed of the material itself, so that the product has good anti-aging performance, and improve the service life. At the same time, the ultraviolet transmittance is low, which avoids the damage of the sunlight medium.
2 Flame retardancy Because it is a metal plate, it has good flame retardancy and can meet the requirements of fire control and safety production.
3 The impact resistance product has high strength and can withstand the impact of hail (strong wind). The impact strength test shows that the middle and upper part of the sample is free to fall down with a 1kg steel ball 1.5m away from the top of the wave crest, and the product is free of fractures and perforating cavities.
4 The surface of anti-static products is treated by electrostatic spraying. After being exposed to sunlight, the dirt of the agricultural production system attached to the product surface can be oxidized and decomposed. In addition, its super hydrophilicity makes the dust easy to be washed by rain, which has a self-cleaning effect without maintenance costs.
Windshield type:
The forming width of single peak dust-proof screen (monomer) is between 250mm-500mm, the peak height is 50mm-100mm, and the length can be processed within 7.2m. The plate thickness is 0.5mm-1.5mm, within the above range, it can be processed according to the customer's requirements.
Double peak dust-proof net (double body)
The molding width is between 400mm-600mm, the peak height is 50mm-100mm, and the length is within 7.2m. The plate thickness is 0.5mm-1.5mm, within the above range, it can be processed according to the customer's requirements.
The forming width of the three peak dust-proof screen (three body) is 810mm - 910mm, the peak height is 75mm, and the length is within 7.2m. The plate thickness 0.5mm-1.5mm can be processed according to the drawing.

The peak height of 7.5cm has better wind protection effect, which is the conclusion drawn by the wind tunnel test of the National Academy of Sciences.
Dust screen has the characteristics of high and low temperature resistance, acid and alkali resistance, aging relief, high strength, long service life, etc. The construction is mainly divided into three steps:
1. Underground foundation of dust-proof net: prefabricated concrete block or cast-in-situ underground foundation.
2. Dust screen support structure: "dust screen" is supported by steel support, and the support structure has no special requirements. The main consideration is to provide enough strength for the "dust screen" to withstand the damage of strong wind, and then consider the overall beauty. In engineering design, the wind speed of 30m/s and wind pressure of 750Pa can be taken as design parameters.
3. Installation of dust screen and wind deflector: theory of wind and dust deflector: service life 15~20 years. Operating ambient temperature: - 40 ℃; ＋ 80 ℃ 。 The connection with the support is fixed by screws and pressing plates. Through the engineering application in recent years, the comprehensive dust suppression effect of the dust screen is very obvious. The comprehensive dust suppression effect of single-layer dust screen can reach about 65%~75%, and that of double-layer dust screen can reach about 75%~85%. Therefore, the setting of dust screen has effectively protected the environment. At the same time, the neat and beautiful dust-proof net has established a landscape for these areas.
The dust-proof mechanism of the "dust-proof net" is based on aerodynamics. When the wind passes through the "dust-proof net" composed of "wind and dust suppression plates", two phenomena appear behind the wall: separation and adhesion. The opening interferes with the airflow up and down, reduces the wind speed of the incoming wind, and greatly loses the kinetic energy of the incoming wind; Reduce the turbulence of wind and eliminate the vortex of incoming wind; It is generally believed that air flow separation occurs at the top of the wind deflector. The area between its departure point and attachment point is called the departure zone, and the length of this section is called the characteristic length or effective shielding distance of the wake area. The dust suppression effect or shielding effect of the "dust screen" depends on the characteristic length and wind speed of the windward wake area.
Dust net is also called windproof and dust suppression wall, windproof wall and windproof net.
