摘要:
采用污垢热阻动态试验法对波纹管和光管的流动阻力、污垢性能和传热性能进行实验研究，用氯化钙和碳酸钠配制硬度为800mg/L的硬水，在流速为0.25m/s，水浴温度为60℃的条件下，对两者析晶污垢进行了对比实验.两套实验系统都在一个恒温水浴内，设备系统的主体用两根管模拟换热器，一根为光管，另一根为波纹管.实验中，水泵将工作介质由低位水箱送至高位水箱，高位水箱向实验管分别同时提供水源，通过溢流式水位调节器保持恒定的水位.结果表明，波纹管具有良好的抗垢性能，表现出诱导期长、结构速率慢、污垢热阻小等优点；其平均传热系数都大于光管，表现出了良好的强化传热特性.
Abstract:
The flow resistance,the fouling performance and heat transfer performance inside the corrugated tube and the plain tube were studied.The calcium choride and sodium carbonate were used to prepare the solution with hardness of 800 mg/L,flow rate of 0.25 m/s and water temperature of 60 ℃ in the experiment.The crystallization fouling of the corrugated tube and the plain tube was compared.Two experimental systems were both in a constant temperature water bath.The main device had two analog heat exchange tubes,one was plain tube,the other was corrugated tube.In the experiment,pumps transported the working fluid from the low water tank to the high water tank.The high water tank provided water to the two tested tubes at the same time.The overflow type water level regulator was used to maintain the water level constant.The experimental results show that the corrugated tube exhibits a good antifouling performance.The corrugated tube has advantages of smaller fouling thermal resistance,longer induction period and smaller fouling thermal resistance,and the average heat transfer coefficient of which is also superior to plain tubes,exhibiting a good heat transfer enhancement feature.
