Engineering characteristics

Features of windbreak dust suppression net products:

1.An environmental protection requirement, the input of the silo is too large, a form of compromise treatment, lower cost, and general environmental protection function. The environmental protection ability is worse than the storage shed, but the effective dust suppression ability can reach more than 65~85%.

2.A good treatment plan for the temporary open yard used for a long time.

Application Area

1.Coal storage yards of power plants, coal mines, coking plants, coal washing plants, etc.

2.Coal storage yards and various stockyards in ports and terminals

3.Various open yards for enterprises such as steel, building materials and cement

4.Coal storage yard of railway and highway coal consolidation station

5.Temporary construction sites for construction and road works


Wind and dust suppression walls are widely used in large (medium) open-air coal storage plants and bulk cargoes such as coal, ore powder, sand ash, etc. In the storage or work operations, the weather is often polluted by dust and dust. In the surrounding environment, the use of wind and dust suppression walls has a dust suppression rate of about 65%–85%, which can effectively play the role of wind and dust suppression.

The punching fractures of the wind and dust suppression wall are easy to corrode. In order to avoid the fractures after the windshield is punched by the sulfur dioxide corrosion in the industrial atmosphere of the coal yard, after the electrostatic powder spraying of the wind and dust suppression net is full, it is water-resistant and wear-resistant , Oil resistance, good insulation, beautiful and beautiful appearance. The dust suppression rate can reach more than 80%. Various colors can be customized according to needs.

1.The wind deflector must be firmly fixed to the structure. The structure can use BJMB structure or welded structure, but make sure that the wind will not blow them down

2.Flexible use, small investment, and occupied land can be re-planned to use functions after several years.

3.The material is very important. The place of use is generally in a corrosive environment. It is important to pay attention to the anti-corrosion ability of the material. Avoid structural corrosion and damage to windshields due to component corrosion.

Process Description

The design and construction of wind and dust suppression walls are mainly divided into three parts:

(1)Underground foundation: Precast concrete blocks or cast-in-place underground foundation.

(2)Supporting structure: engineering design parameters according to wind speed. Supported by steel brackets, the brackets mainly provide sufficient strength for the “wind and dust suppression wall” to resist the damage of strong winds, and secondly, consider the overall beauty. The main body of the support is made of steel pipe, and the reinforced concrete pillar is used as the support of the “wind and dust suppression wall”.

(3)Wind and dust suppression wall installation: The wind and dust suppression wall is formed by pressing inorganic non-metallic materials at one time. The service life is 15-20 years. Ambient temperature: -40℃ to +80℃, the connection is fixed by screws and pressure plates. The specific size, curvature and opening rate of the wind and dust suppression wrench should be designed according to the actual situation of the yard.

(4)Retaining brick wall: In order to prevent the overflow of slime water after rain and snow, a 1-3 meter retaining brick wall can be set under the windshield. Use effect of wind and dust suppression net (wall): The comprehensive dust suppression effect of wind and dust suppression net (wall) is very obvious. The comprehensive dust suppression effect of the single-layer wind and dust suppression wall can reach 65% to 85%, and the comprehensive dust suppression effect of the double-layer wind and dust suppression wall can reach 75% to 95%. It has obvious features such as low investment cost and no running cost for this technology.

(5)The calculation of the structure must have sufficient safety and cannot be weakened structurally.

(6)The use of materials must also be sufficiently resistant to corrosion. Many windshields have a very low cost, and safety risks quickly emerge, which is equivalent to turning the entire storage area into a dangerous zone (the structure collapses and the panels are blown off).
