The 100-meter remotely controlled mist cannon machine for coal sheds mainly achieves dust suppression through "high-pressure atomization + precise direction control".
Its working principle consists of three steps:
Water supply and pressurization:
The water pump pressurizes clean water (or water mixed with dust suppressant) to a high pressure and delivers it to the atomizing nozzles of the mist cannon machine through pipelines.
Atomization into mist:
When the high-pressure water flows through the nozzles, it is cut and broken into tiny water droplets with a diameter of 50-200 microns (close to the particle size of dust), forming a "mist curtain".
Long-range spraying and control:
The fan generates strong air flow to spray the water droplets to a 100 meter range along a set direction (horizontal/vertical). At the same time, the remote control system (such as wireless remote control, PLC) adjusts the rotation angle, spray flow and start-stop of the mist cannon machine. The water droplets collide with and adsorb the suspended dust in the coal shed, forming particles that settle, thereby achieving the dust suppression effect.
