板式换热器清洗的作用和目的主要有两点：
The function and purpose of plate heat exchanger cleaning are mainly two points:
第一： 恢复生产
First: resume production
在工业生产的过程中，有的时候会因为操作不当引起的突发情况造成个别设备或者局部管道线路结垢、堵塞，影响生产的正常运行。对于这时的情况，主要是快速的清除污垢，保证生产装置可以正常的运转，恢复正常生产状态。
In the process of industrial production, sometimes due to improper operation caused by the sudden situation, resulting in individual equipment or local pipe line fouling and congestion, affecting the normal operation of production. For this case, the main is to quickly remove dirt, to ensure that the production unit can work properly, to resume normal production.
第二： 恢复效率
Second: restore efficiency
比如化工设备结垢造成板式换热器等设备传递热量热系数减少，管道流通面积的减少或者流通阻力增大，使能、物等消耗增加，生产效率明显下降。这时通过清洗除垢来恢复生产设备的生产效率。
For example, chemical equipment fouling, resulting in plate heat exchanger and other equipment to transfer heat, heat coefficient reduction, the flow of the pipeline area reduction or flow resistance increased, so that energy, material consumption increased, production efficiency decreased significantly. At this time, the production efficiency of the production equipment is resumed by cleaning and descaling.
