针对壳管式换热器提出采用换热管束高压头强力轮替冲洗工艺除污。介绍了新型强力自冲污换热器的结构及原理,分析了污水换热器强力自冲污的可行性,通过设计计算及经济性分析给出了技术经济可行的冲洗方案——单次冲洗10~20根换热管。
Puts forward the technique of flushing the heat exchanger bundles alternately with high head water for shell-and-tube heat exchangers. Presents the configuration and principle of a new self-flushing heat exchanger. Analyses the practicability of the technique. Gives the feasible flushing scheme through the design calculation and economic analysis, which is flushing 10 to 20 tubes once.
