Introduction of on line circulating pickling technology for casing heat exchanger
YUE Jian-wei;ZHANG Wen-kang;Shandong nanshan donghai Alumina Co.,Ltd.;
Tube heat exchanger is the main heating equipment currently used in large scale chemical enterprises, but the equipment operation after a period of time, scarring effects will produce a layer of dense inner tube wall heat transfer effect. So how to thoroughly clean out this scar, is the key to improve the effect of heat exchanger tube at. This paper mainly introduces the Bayer process of alumina production, the dissolution process of casing in the heat exchanger tube to clean up the scale circulation pickling technology in online.
