摘要

华电宁夏灵武发电有限公司3、4号超超临界2×1 060MW机组凝结水精处理系统采用CSK40高交联度凝胶型阳离子交换树脂与CPA12大孔型阴离子交换树脂。混床投运15个月后对树脂性能跟踪检测结果表明:阴、阳树脂依旧保持良好的性能

仅阴树脂PSS吸附容量有所降低

但仍能维持较高的物质传递系数;在标准运行条件时

混床出水水质达到设计要求。

Abstract

The high crosslinked gel type cation exchange resin(CSK40)with oxidation-resistant ability(durability)

and porous type anion exchange resin(CPA12)which has a property of antiorganic contamination

were applied in condensate polishing system of 1 060MW unit in Huadian Ningxia Lingwu Power Generation Co.

Ltd.Detection of the running resins was conducted after15months since they were put into service.The results showed the resins maintained high quality.Although the value of PSS adsorption capacity of anion exchange resin decreased to a certain extent

the change of PSS leachable rate of cation exchange resin and mass transfer coefficient(MTC)of anion exchange resin was still small.Therefore

it is considered that this type of resin combination has high conformity to CP of air-cooled thermal power plants that with very high condensate temperature and under very sever operation conditions for resins.
