Pipeline cleaning method and remote-controlled spin-washing type pipeline cleaning robot used

Abstract

The invention relates to a pipeline cleaning method and a remote-controlled spin-washing pipeline cleaning device. The method is to seal the pipeline in sections inside the pipeline, first rotate and spray high-pressure water / cleaning liquid to the inner wall of the pipeline in the sealed section, and then stir the pipeline with blades. The swirling flow is generated in the sealing section of the pipe, and the dirt adhering to the inner wall of the pipe is strongly removed by spraying, soaking, and swirling impact; the cleaning process will not cause any damage to the inner wall of the pipe. The invention has the characteristics of good pipeline cleaning effect, strong applicability, low device manufacturing cost and convenient operation; adopts a unique spin washing method, can thoroughly clean the dirt attached to the inner wall of the pipeline, and has high medicament usage rate and small dosage; unique Some segmental cleaning methods can avoid pollution to other pipeline areas during the cleaning process.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to a pipeline cleaning method and a remote-controlled spin-washing pipeline cleaning robot used therefor, which is especially suitable for the cleaning of oil extraction and oil transportation pipelines. Background technique [0002] Pipes are composed of pipes, pipe joints and valves, etc. After connection, the pipes are used to transport gases, liquids or fluids with solid particles. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure of the pipeline to the low pressure. It can also be transported by the pressure or gravity of the fluid itself. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. [0003] During the transportation of the pipel...

Problems solved by technology

At present, the commonly used pipeline cleaning equipment is mainly used in the cleaning of large diameter and short distance pipelines. For long distance or small diameter pipelines, remote control robots are usually used for cleaning, but the remote control robots currently used for pipeline cleaning generally have complex structures. , cumbersome operation, high production cost, large application limitations, and high failure rate; in addition, the water consumption is huge when using high-pressure water cleaning, and iron brushes, scrapers, etc. are used as cleaning components to operate, which may easily cause residues on the inner surface of the pipeline. Grooves, which exacerbate the rate at which pipes re-foul
