In-pipe composite visual automatic descaling device and descaling method

Abstract

The invention discloses an in-pipe composite visual automatic descaling device, which includes an ultrasonic descaling component, a mechanical descaling component and a power component; the ultrasonic descaling component includes: an inner shaft, a four-way connector, a claw head arm lever Rod and ultrasonic descaling claw head; mechanical descaling components include: connecting ring, support wheel, device chamber, wheel brush, external rotor motor, jet component and connecting plate; the power component is fixedly installed on the side of the connecting plate away from the jet component, And the other end is equipped with an infrared camera. The invention also discloses an in-pipe composite visualized automatic descaling method. The in-pipe composite visual automatic descaling device and descaling method provided by the present invention ensure that pipes of different sizes and various forms of scaling can be cleaned stably and efficiently without damaging the pipelines, and the descaling Dirt effect visualization.

Description

technical field [0001] The invention relates to the technical field of pipeline maintenance equipment, in particular to an in-pipe composite visualized automatic descaling device and a descaling method. Background technique [0002] Pipeline transportation is currently the main way of oil and gas transportation. The medium transported in the pipeline is mainly water and oil, which contain organic matter, H 2 S, CO 2 , a variety of ions, and impurities such as mud and sand, so it is easy to form scales such as carbonates, sulfates, and sulfides, which will cause pipeline blockage, reduce pipeline transportation capacity, and have certain safety hazards. [0003] At present, the commonly used scale treatment technologies mainly include mechanical methods and chemical methods. Chemical descaling is mainly to dissolve and remove scales by chemical methods, including chelating agent solvent cleaning, pickling, etc., and choose different chemical reagents for different scales; ...

AI Technical Summary

Problems solved by technology

[0006] (1) Without a visual device, it is impossible to judge the descaling effect, and it is difficult to completely remove the scale in the pipe. In the process of descaling, it usually needs to be cleaned repeatedly many times, the equipment is easily damaged, and the pigging efficiency is low;

[0007] (2) The descaling form is single, the effect is unstable, it is difficult to deal with the stubborn adhesive scales produced by carbonates, sulfates, sulfides, etc., the scope of application is relatively narrow, it is difficult to travel in the pipeline, and it is difficult for corrosion pits in the pipeline The scale removal is also relatively weak
