Research on a Removing Fouling Technology for the Sewage Heat Exchanger

摘要

Based on the particularity of the fouling in the sewage heat exchanger, this paper proposed a new heat exchanger with on-line draw-ring removing fouling technology, focused on the structure and principle of this heat exchanger, designed and manufactured the experimental prototype. After the experiment on this prototype with the scraper-ring mechanism or not for one month, the experimental results show that this heat exchanger has a very perfect removing fouling effect. That will provide a new concept for the broaden use of sewage heat exchanger.
