Water-uninterrupted pipeline biological membrane and growth ring collecting device

Abstract

The invention belongs to the technical field of drinking water, and particularly discloses a water-uninterrupted pipeline biological membrane and growth ring collecting device which comprises a main pipeline, general pipelines, a bypass pipe, an upper end valve and lower end valves. The general pipelines are arranged at the two ends of the main pipeline and communicated with the main pipeline, the lower end valves are arranged in the general pipelines corresponding to the two ends of the main pipeline, three-way valves are arranged on the sides, away from each other, of the two lower end valves, and the bypass pipe is arranged at one side of the general pipeline; the two three-way valves are communicated with each other through a bypass pipe; and the upper end valves are arranged in the two ends of the bypass pipe. the main body pipeline is formed by combining the two semicircular pipelines and the connecting piece, so that the main body pipeline can be more conveniently disassembled by a worker, and the pipeline growth ring and the biological membrane can be continuously collected under the condition that water is not cut off.

Description

technical field [0001] The invention relates to the technical field of drinking water, in particular to a biofilm and growth ring collection device for continuous water pipelines. Background technique [0002] Corrosion aging in water supply network is a very common phenomenon. The aging and corrosion of the pipe network will often form growth rings and biofilms inside the pipes. The derivative products after the operation of these pipe networks seriously affect the water quality of the pipes. The growth of the growth rings will also reduce the diameter of the pipes, reduce the cross-section of the water, and increase energy consumption. Therefore, how to effectively monitor these risk points and collect data to quantify its change mechanism has become the focus of the water supply industry. [0003] However, the pipeline has been buried underground for a long time. If the data is collected by cutting the pipeline, firstly, the growth ring and biofilm formation process cann...

AI Technical Summary

Problems solved by technology

[0003] However, the pipeline has been buried underground for a long time. If the data is collected by cutting the pipeline, firstly, it is impossible to linearly monitor the growth ring and the formation process of the biofilm. Second, the construction is not cheap and the sample should be destroyed. In order to ensure the smooth operation of the pipe network, the third is that if the water is cut off, sampling will inevitably affect the water supply of some branch pipes

[0004] Therefore, there is a great need for a device to solve the above-mentioned inconvenient sampling problem, and at the same time, it can continuously monitor the growth ring and biofilm of a single pipeline.
