摘要:

通过对某单位填料式凉水塔的调查,发现经过长时间运行,因填料损坏、细菌滋生而造成循环水的沟流、束流、堵塞现象严重,使凉水塔换热效率下降,风阻增加,造成风机电流增大,运行费用提高,而且由于填料需定期更换也增加了维修成本。因此需要对填料式凉水塔进行系统改造,措施有:用GPL高效低压离心喷雾系统代替填料的喷水系统改造;用三元流叶轮更换原循环水泵的普通叶轮;调整风扇角度等。改造后,循环水被喷射成0.51.0 mm的微小雾滴,气液接触表面积增加,并延长了水滴在塔内的停留时间,提高了换热效率;由于风阻降低,凉水塔的风机电流显著下降,运行费用大大降低,取得了很好的效果。

Abstract:

This article through to some unit packing type water tower survey and found that after a long runfor packing damagebacterial growth and cause recirculating water channel flowbeamchocking phenomenon and seriousmake cool water tower thermal dropwind resistance increasescausing fan current increasesthe operating cost is improvedand due to packing must change regularly also increased maintenance cost. Therefore need of the filler type water tower system transformationmeasures areuse 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 measuresafter the transformationthe circulating water is ejected into 0.51.0 mm small droplets gas-liquid contact surface areaincreasesand longer drop in tower stay time and improve thermal. Because the wind resistance is reducedcool water tower fan current significantlythe operating cost is reduced greatlyand good results have been achieved.
