Research on Spring-Type Brush On-Line Cleaning Technology inside the Exchanger Pipe

Fouling in sewage heat exchanger mainly restrict large-scale application of sewage-source heat pump. This article introduces the influence of scaling on heat transfer and pressure drop. Based on the scale removal methods home and abroad, excogitates on-line cleaning method of biofouling in sewage-source heat pump, and briefly introduces the principle of on-line cleaning method.
