火力发电厂循环水管道内壁牺牲阳极阴极保护设计及施工

以草桥电厂埋地循环水管道内壁阴极保护工程为例,简要介绍了阴极保护的原理,研究了循环水管道内壁牺牲阳极阴极保护的设计和施工方法,包括管道内壁牺牲阳极阴极保护施工所需的机械通风系统的设计和施工方法的研究。阴极保护工程实施结果表明,本研究采用的阴极保护设计和施工方法合理,管道内部通风系统的设计和安装合理有效。

Design and Construction of Sacrificial Anode Cathodic Protection for Internal Surface of Buried Circulating Water Pipeline in a Thermal Power Plant

Taking the project of cathodic protection for the buried circulating water pipeline of Caoqiao Power Plant as a case, the principle of cathodic protection is briefly introduced and the design and construction method of sacrificial anode cathodic protection for the internal surface of the buried circulating water pipeline are presented, which include the design and construction approaches on the ventilation system required for the construction of the project. The implementation of the cathodic protection project shows that both the design and construction methods for the cathodic protection and ventilation are reasonable and effective.
