换热站板式换热器免拆化学清洗剂配方和试验方法

Formula and Test Method of Chemical Cleaning Agent for Plate Heat Exchanger in Heat Exchange Station Without Dismantling

板式换热器清洗几乎是每个供热公司每年都需要面临的任务。免拆卸化学清洗可以减少工人拆卸、复装板式换热器的工作,还可以减少由于拆卸和复装带来的材料损耗,降低工作强度,提高工作效率。本文介绍了选用免拆化学清洗药剂或配方的试验方法,给从业者提供既能有效清洗板片表面污垢、又能减少对管道和设备腐蚀的化学清洗药剂或配方,并提供试验途径。

Plate heat exchanger cleaning is a task that almost every heating company needs to face every year.Disassembly-free chemical cleaning can reduce the work of workers to disassemble and reassemble the plate heat exchanger,can also reduce the material loss caused by disassembly and reassembly,reduce work intensity and im‐prove work efficiency.This paper introduces the test method for selecting chemical cleaning agents or formulations without dismantling,and provides practitioners with a chemical cleaning agent or formulation that can effectively clean the surface of the board and reduce corrosion to pipes and equipment,and provides a test method.
