Background
During the production process of coal mines, a great deal of coal dust and rock dust, which are collectively called dust, are generated in the processes of mining, digging and transporting. The dust hazard has two main aspects: firstly, the lung of a person is harmful to the human body, and if a large amount of mine dust is inhaled into the lung of the person for a long time, the person can suffer from pneumoconiosis, which is a occupational disease of miners with great harm at present. And secondly, coal dust explosion hazard is caused, when a large amount of coal dust is deposited in a roadway, coal dust explosion can be caused when certain conditions are met, and great threat is brought to safety production of a mine.
Especially in recent years, along with the continuous improvement of the mechanization degree of a coal mine, a large amount of coal dust can be generated, so that gas coal dust explosion accidents happen occasionally, and the safety production of mines and the lives of workers are seriously influenced.
In current dust device, spout through the drop of water after the high pressure nozzle spun atomizing mostly, especially when touchhing the dust of big granule, the area of contact of the drop of water after this kind of dust fall mode makes the atomizing easily less with the dust, and then makes the drop of water after the atomizing be difficult to subside the effect through the mode of parcel to the dust, and then leads to dust fall equipment to be difficult to reach efficient dust fall effect.
