管道死端的问题及危害

The Problems and Dangers of Dead End in Pipe Design

本文分析了管道死端的形成机理,模拟设计了盲管中出现冷凝水及其爆炸当量的计算方法,通过案例探讨了管道死端设计存在问题时的危害。对其中盲管爆炸案例,从冷凝水的产生,爆炸时的冷凝水量,回流后冷凝水被加热的情况,进行了计算、分析,并用案例表明盲管设计不当时,会出现超压爆炸。同时,针对死端设计存在的问题,提出了解决方法。

By analyzing the forming mechanism of dead ends,stimulating calculation method of the appearance of condensed water and the explosion equivalent in blind pipes,this paper discusses the dangers of irrational design of dead ends through case analysis.The case shows blind pipes will explode because of overpressure when the design is not rational.Aiming at the case,this paper calculates and analyzes the appearance of condensed water,the amount of it when exploding,and the heat situation of it when flowing back.Finally,This paper puts forward solutions to the problems in dead end design.
