Abstract
This article through to some unit packing type water tower survey and found that after a long run, for packing damage, bacterial growth and cause recirculating water channel flow, beam, chocking phenomenon and serious, make cool water tower thermal drop, wind resistance increases, causing fan current increases, the operating cost is improved, and due to packing must change regularly also increased maintenance cost. Therefore need of the filler type water tower system transformation,measures are: use the GPL efficient low-pressure centrifugal spray system instead of packing of hydraulic system modification. With ternary flow change original circulating water pump impeller ordinary impeller. Adjust the Angle of fan measures, after the transformation, the circulating water is ejected into 0.5～1.0 mm small droplets gas-liquid contact surface area, increases, and longer drop in tower stay time and improve thermal. Because the wind resistance is reduced, cool water tower fan current significantly, the operating cost is reduced greatly, and good results have been achieved.关键词
