Ash dykes, critical facilities for coal-fired power plants and mines, accumulate massive fly ash and slag year-round. Under wind, gray-white dust spreads like “sandstorms,” polluting surrounding air, accelerating equipment aging, and endangering workers’ health. Traditional sprinklers require frequent trips with limited coverage and high energy use, while automatic 100-meter fog cannon machines now offer a solution with “long-range coverage + intelligent dust control.”
Ash dyke dust has unique traits: covering tens of thousands of square meters, even kilometers, beyond traditional equipment reach; ultra-fine fly ash particles (10-50 microns) spread kilometers in wind, causing regional pollution; frequent vehicle movement disrupts manual dust suppression, posing safety risks. Strict environmental regulations mean excessive dust risks heavy fines and shutdowns, especially near sensitive ecological zones.
Equipped with high-flow turbo pumps and alloy nozzles, they spray up to 100 meters, covering 15,000㎡ per unit. 360° rotating heads and ±15° tilt adjust to undulating terrain, creating seamless fog curtains from dyke tops to slopes, suppressing dust at all heights.
Built-in PM2.5/PM10 sensors trigger auto-start when dust exceeds 0.5mg/m³, shutting down at safe levels—no manual operation needed. The system adjusts spray angle and volume based on wind speed/direction, boosting fog density above 5m/s winds to prevent dust escape.
Anti-corrosion coatings and stainless steel resist alkaline ash erosion and weathering. Large water tanks with auto-fill enable 12-hour continuous operation; anti-freeze heating works in -20℃ to 45℃, solving durability issues in complex dyke environments.
An Inner Mongolia coal-fired power plant’s ash dyke once plagued the area. Covering 800,000㎡ with over 10 million tons of fly ash, strong winds spread dust 5km to nearby villages, sparking 30+ annual environmental complaints. Four sprinklers consumed 200+ tons of water daily but failed to control top and slope dust, with high breakdown rates from frequent climbing.
Last year, 6 automatic 100-meter fog cannon machines were installed every 300m along the dyke edge, forming a circular dust barrier. Linked to the plant’s environmental monitoring platform, it enables remote data and status checks. After six months: third-party tests showed dust levels dropped from 2.8mg/m³ to 0.3mg/m³, meeting national Class I standards; village complaints ceased, earning environmental authority praise.
Costs fell sharply: 6 cannons use 80 tons of water daily, 60% less than sprinklers; near-zero breakdowns cut monthly maintenance from ¥50,000 to under ¥5,000. Vegetation around the dyke recovered as dust decreased, improving the ecosystem.
These fog cannon machines offer more than dust control. Their smart systems record dust patterns, optimizing compaction and covering operations—one energy group increased efficiency by 20% this way. Remote diagnostics prevent downtime, ensuring continuous dust suppression.
For ecologically sensitive areas, precise fog control avoids over-wetting ash, preventing secondary pollution while aiding vegetation recovery, turning ash dykes from “pollution sources” to “ecological buffers.”
With stricter environmental demands, ash dyke dust control is key for enterprises. Automatic 100-meter fog cannon machines, with long range, smart operation, and durability, build effective defenses—cutting costs, meeting standards, and protecting both environment and operations as they lock dust in place with fine mist.
