The Analysis And Evaluation Metho On The Accident Of Central Heating Network At A Time In Beijing District

With the advancement of China's urbanization,the rapid development of urban central heating,central heating pipe network system is becoming more and more complex,and most of the multiple heat source connected to the Internet,annular heating network operation,it has become a new model of large urban central heating pipe network operation.With the continuous development of the central heating scale,the pipe length and the increase of use fixed number of year,the heat increased security hidden danger and accident frequency increases,shortcomings and so on accident influence area.In view of the continuously appear all sorts of accident case,analysis of accident cause of central heating pipelines or networks,the fast repair for the accident,heat recovery,reduce the energy consumption of heating,improve the enterprise benefit has important significance.This paper tries to solve the centralized heating network accident causes and exploratory research on the solution.In Beijing's central heating system,for example,through many years production management practice,the accumulation and summary central heating pipelines or networks in a variety of accident case,and analyzes the cause of the accident,accident treatment measures are proposed,and the countermeasures to enhance the reliability of central heating pipelines or networks in the future.Through summarizing and analyzing accident found that heating pipelines accidents according to the different ways of laying,the cause of accident is also different,grooved central heating pipelines laying most accidents due to the heating pipes,valves,compensator,windproof,drainage equipment caused by corrosion,and directly buried pipeline accidents is more because the anchorage point of failure,external thermal insulation leakage corrosion and thermal insulation to causes such as carbide.Different reasons,different ways of laying,the impact of different diameter,different time of accident is different,according to the causes and effects Settings incident classification and comprehensive evaluation system,and helps to reduce and reduce accident central heating pipelines or networks,at the same time is conducive to rapid disposal of the accident.
