Study of the Mechanisms of Atomization and Dust-Mist Coupling of Aeo-9-Charged Solution

To effectively improve the dust reduction rate of fine dust and prevent the occurrence of secondary dust, dust reduction technology using surfactant-charged solution has been extensively studied. Firstly, the water mist induction-charged atomization mechanism and optimal atomization-charged voltage were determined by the induction-charged spray experiment. Secondly, from the surface tension and spray experiments, the atomization mechanism of the AEO-9-charged solution was determined. Finally, according to the electrostatic adsorption experiment between the bituminous coal and charged droplet, the electrostatic adsorption mechanism was proposed. The contact angle experiment showed the significant effect of AEO-9 in improving the wettability of the bituminous coal. And the molecular simulation was used to study the molecular interaction mechanism of among the H2O, AEO-9, and bituminous coal molecules. The collision wetting ability of the AEO-9-charged solution to coal dust was significant enhanced, and the dust-mist coupling mechanism was revealed at the micro-level
