Description

Ultrasonic online decontamination device for pipeline

Technical Field

The utility model belongs to the technical field of the ultrasonic decontamination, concretely relates to online decontamination plant of ultrasonic wave for pipeline.

Background

The pipeline conveying has the characteristics of safety, convenience, low cost and the like, and is widely applied to the fields of nuclear power, thermal power, seawater desalination, petrochemical industry, municipal administration, fire fighting and the like. As the media (water, oil and the like) conveyed by the pipeline usually contain impurities such as ions, silt, hydrogen sulfide, carbon dioxide and the like, the impurities are easy to accumulate and scale inside the pipeline along with the service life of the pipeline, so that the pipeline is blocked, the pipeline is locally corroded, even the pipeline is perforated and the like, and the safety of pipeline conveying is seriously affected. Especially in the nuclear power field, the pipeline is usually used for conveying radioactive liquid medium, and radioactive pollutants in the medium are easy to gather at dirt to form radiation hot spots, so that external irradiation damage is caused to maintainers.

At present, the modes of chemical decontamination, high-pressure water jet decontamination, mechanical decontamination and the like are mainly used for decontaminating the interior of a pipeline, but the modes all cause certain damage and harm to the pipeline or the surrounding environment of the pipeline, the pipeline is easy to damage after being used for many times, the surrounding environment of the pipeline is movably polluted, and the environment is not environment-friendly; and the decontamination cost of enterprises is greatly improved due to the existing pipeline internal decontamination mode, and the practicability is lower.

Ultrasonic online decontamination is to form shearing force on the interface of the inner wall of the pipeline and a dirt layer through ultrasonic waves and generate a cavity effect in the liquid inside the pipeline, so that the binding force between the dirt layer and the inner wall of the pipeline is reduced, the dirt layer falls off from the inner wall of the pipeline, and the purpose of decontamination is achieved. The decontamination method does not need to disassemble and open the pipeline, can effectively avoid damage and harm to the pipeline or the surrounding environment of the pipeline, is energy-saving and environment-friendly, greatly reduces decontamination cost of enterprises such as electric power enterprises and has strong practicability. In the existing ultrasonic online decontamination devices, in the decontamination process, the decontamination device needs to be manually pushed to move to different target positions on the pipeline for decontamination, or after the decontamination of one section of pipeline is completed, the decontamination device needs to be manually detached and then placed on the next section of target pipeline again, so that the manual waste and the low efficiency are caused, and the decontamination cost is increased.
