Abstract

The invention relates to a vacuum flushing dredging system of a drainage pipe network. The vacuum flushing dredging system comprises drainage pipelines, a pump station water-collecting well and receiving wells, wherein the drainage pipelines comprise drainage main pipes and drainage branch pipes, the output ends of the drainage branch pipes are connected with the drainage main pipes through the receiving wells, the tail ends of the drainage main pipes are connected with the pump station water-collecting well, a flushing device is arranged on each drainage main pipe, each flushing device comprises a buffer pool, a flushing pool, a vacuum pump, a vacuum membrane valve and a siphon unit, one side of the bottom of an auxiliary pool is connected with the bottom of a flushing chamber through the siphon unit, the other side of the bottom is connected with the drainage main pipes, and the top of the flushing chamber is connected with the vacuum pump through the vacuum membrane valve. Compared with the prior art, the vacuum flushing dredging system has the advantages of automatic cleaning, trouble saving, labor saving and the like.

Description

technical field [0001] The invention relates to a flushing and dredging technology in the field of municipal drainage, in particular to a vacuum flushing and dredging system for a drainage pipe network. Background technique [0002] Drainage pipeline refers to the system composed of pipes and channels and their ancillary facilities for collecting and discharging sewage, waste water and rainwater. After the sewage flows from the branch drainage pipe with a large slope into the main drainage pipe with a small slope, the flow velocity decreases, and the sediment and suspended solids carried in the sewage are easily deposited in the main pipe with a small slope and a large diameter. For combined pipelines, the design flow is designed according to the combined flow of rain and sewage in the rainy season. The flow rate of sewage received by drainage pipes in the dry season and the flow rate of sewage in the pipe are much lower than the value in the rainy season, so that the large...
