Experimental Research on Hydraulic Removing Fouling Heat Exchanger (HRF) (Ⅱ)—Fouling removal characteristics of HRF heat exchanger

摘要

In order to investigating the removing fouling characteristics of HRF beat exchanger, the experimental table of flow and heat exchange of urban sewage is established. The experiment results show that the reduction rate of fouling impedance and fouling heat-resistance in a heating periods are both over 70%, when the removing fouling cycle is 10 hours, the cleaning velocity is 5m/s and the cleaning time every time is 1 minute.
