During the stacking and transportation of coal in coal yards, flammable dust is easily generated, which can trigger explosions when encountering sparks. Traditional mist cannon machines lack explosion-proof design and may even become safety hazards. Explosion-proof mist cannon machines address core risks from 3 key dimensions.
The lower explosion limit of coal yard dust concentration is 50g/m³. Explosion-proof mist cannon machines adopt Ex d IIB T4 explosion-proof motors, with no exposed sparks in the circuit. Meanwhile, they quickly adsorb dust through 10-150μm fine mist, controlling the concentration below the safe value and preventing dust from being ignited by electric sparks or mechanical sparks.
High dust and high humidity in coal yards easily cause short circuits and component rust in ordinary mist cannon machines. Explosion-proof mist cannon machines have shells made of 304 stainless steel, with an IP67 waterproof rating, and dust-proof filters installed in pipelines. They can resist coal dust accumulation and rain erosion, with a failure rate 80% lower than that of ordinary models.
If a coal yard shuts down due to dust explosions or failure to meet environmental standards, the daily loss exceeds 100,000 yuan. Explosion-proof mist cannon machines support 24-hour continuous operation and are equipped with dust concentration sensors for automatic start-stop. They not only meet environmental requirements but also eliminate shutdowns caused by equipment safety issues, ensuring stable production.
When choosing mist cannon machines for coal yards, the core lies in “explosion-proof” rather than “dust suppression“—explosion-proof mist cannon machines are not only dust inhibitors but also safety barriers, building a solid defense for coal yard production.
