Coal Shed Dust Hard to Control? Fog Cannon Machine Builds Full-Space Dust Reduction Barrier​

In coal sheds, coal dust raised by shuttling loaders during unloading spreads like brown smoke. Piled raw coal ripples with dust at the slightest airflow, coating inspectors’ helmets with coal ash and endangering equipment operation. Traditional sprinkling increases coal moisture affecting calorific value, while fog cannon machines offer efficient dust control via “precision coverage + intelligent dust management”.​

Customized Dust Reduction for Coal Dust Traits​

Coal dust’s light, floating nature: particles under 10 microns suspend for hours, and loader airflow pushes dust upward. Fog cannon machines crush water into 50-150 micron droplets via three-stage atomization, adsorbing coal dust targetedly. Their 320° rotating spray arms cover 20-120m radii, paired with overhead rail-mounted fog cannons to form a 3D fog network capturing even top coal pile dust.​

Key is the intelligent linkage system: dust sensors trigger activation when PM10 exceeds 0.5mg/m³. Fog cannons sync with loader movement, avoiding waste. Energy research shows this dynamic mode saves over 35% water vs fixed-time spraying.​

Case: Thermal Power Plant’s Coal Shed Dust Revolution​

A Shandong thermal power plant’s 12,000㎡ steel coal shed faced severe dust. 800 tons of daily coal flow caused 3.2mg/m³ dust during unloading. Workers needed N95 masks, and monthly equipment maintenance involved cleaning thick coal dust from radiators. Surrounding TSP exceeded standards, pressuring the plant to rectify.​

Last year, 6 intelligent fog cannon machines were installed: 4 fixed units on both sides covering storage areas, 2 overhead rail units targeting high-altitude dust. Linked to loader GPS, they activate in unloading zones, forming 3m fog “barriers”.​

Three months later, PM10 stabilized below 0.3mg/m³. The inspectors reported no instances of coughing when masks were not worn; the equipment’s heat dissipation efficiency increased by 15%. maintenance extended from monthly to quarterly. Surrounding TSP dropped 62%, passing environmental checks. Coal moisture increased only 0.2%, not affecting boiler efficiency.​

Hidden Values Beyond Dust Reduction​

Fog cannon machines brought unexpected benefits. Traditional sprinkling caused monthly loader slips, but dry floors post-installation eliminated annual accidents.​

Cost comparisons: 3 daily manual sprinklings used 15 tons of water; 6 fog cannon machines operating intelligently used 8 tons daily with under 50 yuan electricity, saving nearly 60,000 yuan yearly in water and labor.​

For large coal enterprises, remote control via mobile APP lets managers monitor dust and equipment status without frequent shed entries, enhancing safety and efficiency.​

Coal shed dust control impacts environmental compliance, safety, and health. With targeted design, proven results, and low costs, fog cannon machines are ideal. As loaders enter, their mist settles coal dust, protecting the environment and clearing paths for green production.
