摘　　要：换热设备积垢热阻大 ,能耗高 ,换热设备污垢使中国工业生产蒙受的损失每年达百亿元以上。发明了换热管内微型液轮机用以实现换热设备在线除垢、防垢并强化传热。当管内液体流动时 ,液轮机自行运动。由于转子不断刷洗换热管 ,换热管内很难结垢 ;如果原有积垢 ,也可除垢 ;而且滞流边界层受到不断的扰动 ,强化了传热。工厂试验证明 ,换热管内微型液轮机在线除垢防垢效果好。该技术对节能有重要意义。介绍了换热管内微型液轮机的工作原理、转速特性。Since the heat resistance produced by fouling of heat exchangers is great and the energy consumption is high,the fouling of heat exchangers has brought about billions of dollars of economic losses of China in dustries In order to realize the foul removing/preventing on line and enhance h eat transfer,the miniature hydraulic turbine in the heat exchanger tube is inven ted Such hydraulic turbine works of itself while the fluid in the tube flow As the rotor continuously scrub the heat exchanger tube,it is hard to form the new foul and easy to remove the original foul Furthermore,the hydranlic turbine en ables the sticky boundary layer to be disturbed,and enhance heat transfer The i nd ustrial tests prove that using this miniature hydraulic turbine in the heat exch anger tube has a good effect on foul removing/preventing Utilizing this technol ogy has great significance in saving energy The working principles,the rotation al speed properties,the flow resistance properties and the industrial tests for foul removing/preventing on line of the miniature hydraulic turbine in the heat exchanger tube are introduced
