摘要
在电厂供热管网维护过程中,管网疏排水、放水、分段隔离等操作大都需要进入阀门井等受限空间内进行工作。受限空间一直是安全事故的高发区域,作业风险点多,作业风险性大。从某电厂供热管网实际情况出发,介绍了部分降低供热管网受限空间作业风险的措施,有效地保障供热管网安全稳定运行,降低受限空间事故发生率。
During the maintenance of the heating pipe network of a power plant, the drainage, discharge and segmented isolation of the pipe network mostly need to work in a confined space such as the valve well.Confined space has always been a high incidence area for safety accidents with many operation risk points and high operation risks. Based on the actual situation of the heating pipe network of a power plant, several measures to reduce the operation risks in confined space of the heating pipe network are described so as to effectively ensure the safe and stable operation of the heating pipe network and reduce the incidence of accidents in confined space.
