| 摘 要： | 以内置自转塑料螺旋扭带换热器为研究对象,对换热管中有、无自转扭带时污垢的粘附速率、换热器的动态污垢热阻、管壁的磨腐速率进行了工业应用对比试验研究。研究结果表明:自转清洗扭带的防垢、除垢、清洗效果显著,扭带管的污垢平均粘附速率是普通光管的54%;动态污垢热阻比光管下降了30%;塑料扭带对管壁的磨损微乎其微。为自转螺旋塑料扭带的工业应用推广提供了依据。

| Abstract: | The contrast experimental researches on the adhesive velocity of fouling,the dynamic thermal resistance of fouling,the abrasion velocity of the tube wall for the heat exchangers between smooth tubes and tubes with the self-cleaning plastic twisted-tape were carried out.The results indicate that the average adhesive velocity of fouling for the tubes with inserted twisted tape is only 54% that of the smooth tubes,the average dynamic thermal(resistance) of fouling is 30% smaller than that of the smooth tube,the abrasion velocity of the tube wall is very small.These investigation results will provide experimental support for the industry applications and popularization of self-cleaning twisted tape in heat exchangers. |
