Abstract

The invention discloses an in-pipe combined type visual automatic descaling device which comprises an ultrasonic descaling assembly, a mechanical descaling assembly and a power assembly. The ultrasonic descaling assembly comprises an inner shaft, a four-way connector, a claw head arm rod, an arm rod supporting rod and an ultrasonic descaling claw head. The mechanical descaling assembly comprises a connecting ring, a supporting wheel, a device cavity, a wheel brush, an outer rotor motor, a jet flow component and a connecting disc. The power assembly is fixedly installed at the side, away from the jet flow component, of the connecting disc, and an infrared camera is installed at the other end of the power assembly. The invention further discloses an in-pipe combined type visual automatic descaling method. According to the in-pipe combined type visual automatic descaling device and the descaling method provided by the invention, pipelines with different sizes and in various scaling forms can be cleaned stably and efficiently on the premise that the pipelines are not damaged, and the descaling effect is visualized.

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; ...
