In industries such as power generation, metallurgy, mining, and papermaking, open-air raw material yards serve as a critical link in the centralized storage, processing, and transshipment of bulk raw materials and fuels. Dust pollution has long been a persistent challenge in these yards, not only degrading air quality in the work areas and surrounding environments but also posing serious risks to workers’ health and safety. Developing a systematic dust control solution that addresses the source, process, and end-of-pipe stages is key to meeting environmental standards and ensuring production safety.

Spray Dust Suppression Solution

Three-Pronged Dust Suppression Strategy

1. Source Dust Suppression

Wet dust suppression technology is employed at the source by spraying water mist or dust suppressants onto the surface of material piles to maintain a moisture content of >20% and reduce dust generation.

2. In-Process Dust Control

Deploy dry fog dust suppression systems at specific locations such as transfer points, discharge openings, and crushing points to agglomerate and settle dust at the source. This method requires low water consumption and does not affect material properties.

3. End-of-Process Dust Control

Install high-efficiency dust control equipment at the end of the process, such as mobile mist cannons and fixed mist columns.

Spray Mist

Core Dust Control Equipment

Raingun Series Dust Control Spray Guns

Widely applicable to large-scale dust-polluted areas such as coal yards, stockpiles, ore storage yards, and truck access roads in industrial and mining enterprises—including steel and metallurgy, power generation, ports and terminals, railway freight yards, mines, coal mines, non-ferrous metals, and coal-coke chemical industries—these spray guns offer an ideal solution for extensive dust pollution control.

Advantages of the Raingun Series Dust Suppression Spray Guns:

1. Specifically designed for dust suppression applications, delivering highly effective dust reduction;

2. Unique flow path and elevation angle design ensure excellent spray range and atomization;

3. Unobstructed orifice design reduces water quality requirements, allowing the use of turbid water and conserving fresh water;

4. Multiple elevation angle options to accommodate different types of stockpiles;

5. Utilizes a vertical swing arm drive mechanism, ensuring the spray gun rotates steadily and slowly during operation for exceptionally smooth misting;

6. Precise spray arc adjustment mechanism that does not creep over time;

7. The spray gun base and key components are made of high-quality materials such as copper and stainless steel, ensuring a long service life.

Long-Range Fogger

A high-performance water pump atomizes water droplets into a fine mist matching the size of dust particles. Driven by a powerful fan, this fine mist is projected over long distances. The fine mist particles, upon contact with airborne dust, wet the dust particles’ surfaces and increase their weight, causing the dust to continuously agglomerate and grow. Under the force of gravity, this rapidly suppresses and settles the dust, achieving a dust suppression rate of up to 98% while saving over 90% more water than conventional spray gun equipment.

DustClean Jet Series Dry Fog Nozzles

The DustClean Jet series of dry fog nozzles generates ultra-fine dry fog particles ranging from 10 to 40 microns. These particles exhibit exceptional adsorption and capture capabilities for dust suspended in industrial environments (where most particles are around 50 microns in size), causing dust particles to rapidly agglomerate into clusters. Under the combined effects of gravity and the kinetic energy of the spray, rapid and efficient settling is achieved. At the same time, water consumption is minimal, allowing for effective control of material moisture content.

The DustClean Jet Series dry fog nozzles are widely applicable for controlling fugitive dust in industrial and mining enterprises, including steel and metallurgy, thermal power generation, ports and terminals, cement and building materials, mining and beneficiation, non-ferrous metals, coal and coke chemical industries, papermaking, and railway freight yards. They are suitable for equipment such as mining and beneficiation machinery, loading and unloading equipment, stockpiles, raw material yards, and material handling systems, as well as for dust control in factory buildings.

Spray provides enterprises with comprehensive, water-saving, efficient, stable, and reliable dust control solutions covering all scenarios, helping companies meet national and local environmental emission standards and achieve sustainable development goals.
