便携式钢瓶回收槽车快速接头段LPG的研究

The Disquition of Recycling in Tank Truck's Ouick-joint Pipeline by way of Portable LPG Cyclinders

液化石油气的槽车运输在业内采用得非常普遍,但在充装完毕后快速接头段内所存液化石油气的排放始终是一个问题,直接排放不仅不利于安全和不经济,而且也不利于环保。便携式回收专用钢瓶是由两用瓶阀来代替原用的单相瓶阀以及在瓶阀与瓶体之间加装一个铜制的过渡接头,利用气相平衡法、气相吹扫法与钢瓶排放法来排放剩余的残液。

Special portable recovery cylinders are modified with a dual-purpose valve instead of the commonlymonophase valve,and an addition of copper adapter joints.The remaining raffinate can be released by usingmethods such as gas phase balance,gas phase purging and gas bomb release,etc.
