粪便真空输送管网与真空站参数的研究与设计

Design of Vacuum Flowing Network and Station for Urban Fecal Transportation

通常设计的真空站抽吸力以 5 5mH2 O为设计标准 ,这 5 5mH2 O抽吸力主要用来克服真空阀件的打开和污物由用户终端到达真空站的过程中遇到的阻力 ,包括提升段的提升损失和管道对气液两相流的摩擦损失 ,如果抽吸力不足 ,将导致污物无法收集到真空站。对真空输送管网和真空站重要参数作了研究与设计。

The vacuum abstract station has function to gather impurities, generally it is designed with vacuum degree of 5 5 mH 2O to win through the valves resistances and obstructs of impurities moving from the terminal of users to the vacuum center, including the head losses in the lifting section and the flowing friction of pipe wall in both the gas and liquid phases. If the vacuum degree is not enough, the impurities will not be possible transported into the vacuum station. The important parameters to design vacuum station and pipeline are researched profoundly.
