【Abstract】 In line with the marked decline in cooling efficiency over prolonged operatio of the packed cooling tower with two layers of cementgrids in the integrated sode plant of a company,a new type of anti-clogging PVC film packing T25-60°and an assembly flat steel support are adoptedfor retrofit after scheme comparison and design calculation.Testing by ano official organization at the provincial level and use by customers prowe thatsuch a retrofit procedure is not only economic and highly effcient but willalso restore comletely the cooling capacity of the original packed coolingtower with cement grids,thereby meeting production requirement.更多还原
