The application relates to the technical field of pipeline
corrosion inhibitor filling devices, and discloses an
intelligent control type pipeline
corrosion inhibitor
ring device and an operation method thereof. The device comprises a main body, a walking mechanism capable of elastically extending is arranged on the outer side of the middle part of the main body, a storage cavity is arranged on the back flow side of the main body, the storage cavity is used for storing
corrosion inhibitors, a
circulating pump and a flow regulating valve are arranged on the back flow side of the main body, the flow regulating valve is connected with the
circulating pump, a plurality of
corrosion inhibitor sprayers are arranged on the inner side and the outer side of the back flow side of the main body at intervals, the outlet of the
circulating pump is connected with the
corrosion inhibitor sprayers through pipelines, and a controller and a monitoring unit are arranged in the main body. The device has a reasonable and compact structure, is convenient to use, can realize in-situ rapid installation of a target protection section of a pipeline in service, does not need to
cut off the pipeline or stop the whole line, can match the
corrosion inhibitor concentration and the flow velocity of a
carrier fluid by combining a PLC controller and adjusting and controlling filling parameters in real time according to the pipeline flow, and can smoothly carry the
medicine by the fluid and uniformly attach the
medicine to the inner wall of the whole pipeline.
