Description

Technical Field

[0001] The invention relates to a cleaning device which is placed in a pipeline and moves along the pipeline, in particular to an oil and water pipeline descaling and cleaning device. Background Art

[0002] At present, some water injection pipelines in oil production plants and oil field gathering pipelines are seriously corroded and scaled. Corrosion, scaling and blockage of oil and water pipelines are common problems that affect oil field gathering and transportation production. As we all know, corrosion and scaling of oil and water pipelines have many hazards. First, the pipeline back pressure rises, increasing the transportation resistance and increasing the pipeline pressure, which not only increases energy consumption, but also creates the risk of pipeline breakage and leakage; second, the pipeline is completely blocked, the pipeline stops transporting, and affects the normal operation of the pipeline; third, the pipeline is severely corroded, which will cause perforation and leakage, shortening the service life of the pipeline; fourth, the scaling and deposition of oil sludge in the pipeline provides a living environment for the massive reproduction of sulfate-reducing bacteria, saprophytes and iron bacteria, polluting the oil and water in the pipeline.

[0003] At present, the main methods for cleaning scale in oil and water pipelines are chemical cleaning and the use of cleaning tools. The chemical cleaning process has safety and environmental risks. The use of cleaning tools is prone to drill jams, and the cleaning is not thorough and the investment is high.

[0004] In order to solve the problem of descaling and cleaning of oil and water pipelines, a "pipe descaling device" is provided in the Chinese utility model patent with application number 201821560216.3, which includes a support mechanism for supporting the oil pipe, a descaling body for being arranged in the oil pipe, a descaling blade arranged on the outer peripheral wall of the descaling body, a guide mechanism distributed in an annular shape, and a power mechanism for providing rotational force for the descaling body, wherein the power mechanism includes a rotating shaft whose length matches the length of the oil pipe, a transmission mechanism and a motor for driving the rotating shaft to rotate. Although this solution can meet the cleaning needs of some oil pipes, the rigid power mechanism and transmission mechanism greatly limit the applicability of the descaling device for descaling longer oil pipes.

[0005] In the Chinese utility model patent application number 201320059442.4, a "pipeline descaling and cleaning device" is provided, which includes a leather cup connecting column, a wire brush, an upper flange and a lower flange. The first leather cup is fixedly connected to the lower end of the first connecting column through the lower flange, and its concave surface faces downward; the second leather cup is fixedly connected between the upper end of the first connecting column and the lower end of the second connecting column, and its concave surface faces downward; the third leather cup has a concave surface facing downward, and its top surface is provided with a wire brush and is fixedly connected to the upper end of the second connecting column with the upper flange. end; the wire brush is a disc-shaped structure with bristles facing outward, and the diameter of the wire brush is larger than the diameter of the third leather cup. The wire brush end is placed in the pipeline along the flow direction of the medium in the pipeline, and moves forward with the thrust of the medium or the pressurizing device under the action of the leather cup, and the dirt in the pipeline is cleaned by the wire brush at the front end. Obviously, this solution is limited to scraping and cleaning a small amount of dirt in the pipeline. When the pipeline is blocked by scaling and the medium in the pipeline does not flow, the descaling and cleaning device cannot move to the blockage point, and it cannot realize the cleaning function of the blocked dirt.

[0006] In addition to the above solutions, high-temperature incineration and chemical cleaning fluid reprocessing are currently commonly used in China for descaling and cleaning. However, the waste gas generated by high-temperature incineration and the waste liquid generated by chemical cleaning fluid reprocessing have complex components and are difficult to handle, which can easily cause secondary pollution. The incineration temperature of high-temperature incineration is difficult to control, and overburning may cause the oil pipe to be scrapped. The chemical cleaning fluid will also corrode the oil pipe and shorten its service life.

[0007] Based on the above reasons, we urgently need an efficient oil and water pipeline cleaning solution. Summary of the invention
