abstract:
The circular air-water atomizing equipment was designed based on the secondary atomization mechanism of the transverse jet in high velocity gas flow.In this paper,the liquid flow field and gas phase flow field of the circular air-water atomizing equipment were simulated by Fluent software.And the effects of different annular angles and tracheal distance on the liquid phase flow in the equipment were analyzed.The gas phase flow in the equipment were also analyzed under different gas flow rates.The results show that the angle of the ring gap should be controlled between 40°and 50°,and the distance from the outlet of the ring to the end of the trachea should be controlled between 2 and 4 mm,so that the droplets and gases are made to have sufficiently large relative velocity and sufficient secondary atomization time and distance.On this basis,the roadway dust reduction test was simulated,which obtained the satisfactory dust reduction effect.
