Days ago，Hanjiawan Coal Company has equipped the underground excavation working face with a water-rotating fog cannon，“The visibility of the return air tunnel in the excavation working face has been improved，The dust concentration has dropped。”The front-line workers in the excavation field were very happy。
In the past, spray dust suppression devices required the spray pipeline to be processed in advance，m88 live casino and sports bettingRequires both water flow and wind pressure before use，Use wind pressure to atomize water flow，Sprayed through the nozzle，Indispensable。As the excavation working face continues to extend，The full-section spray device still needs to be manually moved forward for installation，Time-consuming and laborious。
To change this situation，The company benchmarks through outbound activities、Technical Exchange，Actively introduced the "ZZL-25-type" water-rotating fog cannon。The device is made of thick-walled seamless steel pipe、Wear-resistant bearing、Composed of pressure reducing valve and filter valve，Light weight、Easy to carry，is a new type of environmentally friendly dust reduction spray device。
The operating principle of this device is simple，Water flow filter、After the pressure reducing valve enters the hollow shaft of the rotating device，Spray out from the nozzle holes of the hollow nozzle。After the water pressure reaches a certain pressure，The hollow tube begins to rotate driven by the reaction force of the jet water m88 casino reviewcolumn，Also drives the fan blades to rotate，The wind pressure generated by the fan blades atomizes the water flow and transmits it to long distances。At the underground site，The water mist reaches a longer distance at the same time，It can also achieve larger area coverage，Thus achieving the purpose of dust reduction。At the excavation face，Can achieve good dust reduction、Dust removal effect，Also suitable for dust reduction in enclosed spaces，Reduced safety hazards。
After the device is put into operation，Employee labor intensity is significantly reduced，Dust suppression efficiency is 3 to 5 times higher than traditional spray watering，Easy to operate，Reduces the dust concentration at the work site，The visibility of the tunnel return air flow transportation route is further improved，Increased safety factor，Protected the lives and health of frontline workers。(Li Jintao, Marshal Lu)
