In order to study the screen defogging characteristics of the converter wet dust removal sys-tem,a screen defogging experimental platform was built to study the nonstick screen defogging charac-teristics under different airflow speeds with the change of screen layer number,mesh number and water content.The results show that with the increase of gas velocity,the defogging efficiency increases first and then decreases.In order to avoid the secondary entrainment phenomenon,the airflow velocity in the screen of the converter wet dust removal system should be controlled at 3～4 m/s.The number of mesh layers increases from 2 to 6,the defogging efficiency increases first and then flattens out.When the number of layers is4,the defogging efficiency can reach95%.When the gas velocity is constant,the defogging efficiency increases with the increase of the number of mesh layers and water content,while the flood gas velocity decreases with the increase of water content.
