Application of dust removal technology with active magnetized water spray in fully-mechanized driving face
Wang Wenbin
Abstract：In order to effectively solve the problem of poor dust wetting performance of dust-proof water and the inability of fully-mecha-nized excavators spray to effectively cover the dust source,a water-based medium of activated magnetized water with high efficiency for dust removal was developed.Combined with the simulation results of dust movement and distribution in the working space of fully-mech-anized mining face during the cutting of roadheader,based on the gas-water two-phase spray technology,a spray field with wide atomiza-tion coverage was constructed for the cutting drum of fully-mechanized excavators.The field application shows that the active magnetized water high efficiency spray field can effectively reduce the dust concentration during the excavation of the fully-mechanized mining face,in which the average total dust reduction rate of the working area of the personnel at the fully-mechanized driving face is 87.3％,and the average exhalation dust reduction rate is 84.5％,achieving good dust removal effect.
