AI Technical Summary
In existing dust suppression devices for coal mine roadways, single-layer water curtain nets are easily affected by pedestrians and vehicles, resulting in poor dust suppression effect. Furthermore, the nozzles are prone to clogging, and the sprayed water cannot form an effective mist, causing dust to penetrate the water curtain net and resulting in poor dust suppression effect.
It adopts a double-layer water curtain structure, combined with an adjustable atomizing nozzle and a pneumatic mist core mechanism. The angle of the atomizing nozzle is adjusted through a limiting mechanism and a fixing mechanism. Water and air resonance is formed by an air pump and a water pump to generate fine mist droplets, thereby enhancing the dust suppression effect.
It improved the dust suppression effect in the tunnel, reduced the dust concentration, enhanced the ability to capture and settle dust, and lowered the dust concentration in the tunnel.
