LNG/CNG加气站放散管设计

Design of blow-down pipe in LNG/CNG filling station

放散管在天然气加气站应用广泛,由于其竖直向上并敞口,为放散管设计考虑防雨防沙设施更是必不可少。本文介绍了在笔者参与的加气站设计中所采用的防雨防沙设施用以有效防止雨水沙尘进入放散总管阻碍放散气体的向上排放。

Blow-down pipe is widely designed in natural gas filling stations. Therefore it is necessary for thepipes to prevent rain or sands falling into them as they are vertical and open on the top. It is introduced in this paperabout the measures taken to prevent rainwater or sands accumulated in the bottom of the pipe as little as possible ina natural gas filling station that the write has designed.
