由于清洁的艰难程度是随着垢层厚度或堆积的添加而灵敏增大的,所以清洁距离时间不宜过长,应依据生产设备的特色,板式热交换器换热介质的性质,侵蚀速度及运转周期等状况定时进行检查,修补及清洁。选用化学清洁时,要依据实践请况和水质的不一样所结垢的垢质进行剖析化验别离制造药剂清洁。
    依据板式热交换器的方式,应在换热器的两头留有满足的空间来满足前提(操纵)清洁、修补的需求。固定管板式换热器在设备时,两头应留出满足的空间以便能抽出和替代管子。而且,用机械法清洁管内时,两头都可以对管子进行冲刷操纵。浮头式换热器的固定头盖端应留有满足的空间以便能从壳体内抽出管制,外头盖端有必要也留出一米以上的方位以便装拆外头盖和浮头盖。U形管式换热器的固定头盖应留出满足的空间以便抽出管制,也可在其相对的一端留出满足的空间以便能拆开壳体。

Due to clean difficult degree is sensitive with the add of scale thickness or accumulation increases, so clean distance time shoulds not be too long, should be based on the equipment features, the nature of the heat transfer medium, erosion rate and operating state such as cycle time for inspection, repair and clean.When choosing chemical cleaning, should be based on the practice condition and water quality is not the same, please analyzes the scale and quality of fouling in the laboratory by manufacturing pharmaceutical clean separation.On the basis of the heat exchanger, with satisfy the space should be at the two ends of the heat exchanger to meet the needs of premise (control) cleaning, repair.When fixed tube plate heat exchanger equipment, two head should be set aside to meet space so that it can take out and replace the pipe.And, when clean pipe by mechanical method, can be carried out on the pipe flushing control both ends.Fixed epicranium end of floating head heat exchanger should be left free to meet from housing to take control, outside the cranium end so it is necessary to also set aside a metre above the position of casual split cranium and floating head cover.Fixed cranium of u-tube heat exchanger should be set aside to meet space in order to take control, can also be used in its relatively set aside to meet at the end of the space to open shell.
