Abstract

The invention relates to a vacuum sewage conveying system for crossing an obstacle. The vacuum sewage conveying system comprises a vacuum sewage pipeline penetrating through the lower side of the obstacle, an air pipeline and a ventilation pipeline which communicate with the vacuum sewage pipeline, valve assemblies mounted on the air pipeline and the ventilation pipeline, and a controller used for controlling the valve assemblies to act; one end of the air pipeline communicates with the vacuum sewage pipeline, and the other end extends above the ground; the ventilation pipeline communicates with the upstream end and the downstream end of the vacuum sewage pipeline. The vacuum sewage conveying system for crossing the obstacle relates to a specific technology for avoiding pipeline blockage caused by vacuum degree reduction and solid garbage precipitation in sewage when the sewage passes through the certain obstacle on the vacuum sewage pipeline, so that the conveying distance and the conveying efficiency of the vacuum sewage conveying system are improved, pipeline blockage is reduced to a certain extent, and the system reliability is improved.

Description

technical field

[0001] The invention relates to a technical field of vacuum sewage conveying system applied between a vacuum sewage collection system and a vacuum sewage treatment system, wherein the vacuum sewage collection system is the source of vacuum sewage generation or the front end of vacuum sewage collection, the vacuum sewage treatment system and the sewage after The present invention particularly relates to a vacuum sewage conveying system for crossing obstacles. Background technique

[0002] The vacuum sewage collection and transportation system (referred to as the vacuum sewage system) refers to the vacuum generated by the vacuum pump station (the vacuum here is not absolute vacuum, but a state of decompression or lower than atmospheric pressure) and atmospheric pressure. The pressure difference to collect and transport sewage system.

[0003] Taking the vacuum sewage conveying system in the prior art as an example, its existing defects are described in detail,...
