“The return air alley in the panel area has better visibility，The vision is clearer。”Recently，Hanjiawan Coal Company to increase dust prevention and control efforts，Equipped with cloud and dust suppression devices for underground tunnels。

Previous tunnel spray device，Subject to pipeline water quality、Affected by factors such as the size of the nozzle，The spray atomization effect is sometimes not ideal。After the nozzle is clogged，Need to be cleaned or replaced regularly，Invisibly increases labor intensity。

To change this situation，Company communicates results through active application of benchmarking，Introduced "YCT-10N cloud and dust suppression device"。The main principle is to use a special atomizing nozzle to flow air、Water flow for air-water mixing and atomization，Forms finer and floatable water mist than traditional spray，Atomization accuracy reaches 70 microns，The spray angle can reach 180 degrees，Greatly increases the collision efficiency between water mist and dust。

“We set the spray on time to 2 minutes，Automatic shutdown duration is 30 minutes，Really liberating artificial intelligence。”Original，This device can also freely adjust m88 sports betting reviewthe spray start and stop time，Completely changed the passive situation where shutdown control relies on manual labor or power supply，In addition，This device also uses an external backflush filter，Solved the spray clogging problem from the source。

Last days，The company gradually installs the return air lanes in each underground panel area。“The dust control efficiency will be higher after the cloud dust reduction device is put into operation，Employee labor intensity is significantly reduced，Water consumption is saved 3-5 times compared with before。" Li Huigang, director of the company's one-pass and three-prevention office, introduced。(Li Jintao Song Ya)
