A gas pipeline oil accumulation positioning detection and extraction system

Abstract

The invention belongs to the field of natural gas pipeline safety maintenance, and relates to the detection and suction treatment for the deposition and attachment position and accumulated amount of lubricating oil in the natural gas pipeline. It is characterized in that: the system consists of a pipeline robot and a back-end control system; the back-end control system sets the operating parameters, controls the placement of the recovery system and the gas-liquid separation reservoir, guides and controls the entry and exit of the robot, and performs post-processing on the pumped and discharged oil and gas. Processing: The pipeline robot is controlled by the front-end control system, equipped with a deposition detection module, a three-dimensional space detection module, a data storage module, a power supply module and an extraction and extraction module. Compared with the prior art, the present invention has the following advantages: non-stop detection and processing can be realized, pipeline space shape, oil accumulation shape and accumulation position can be measured in one pass, and accumulated lubricating oil can be processed in one pass, and it can also be used to detect pipeline deformation and deformation. defect.

Description

technical field [0001] The invention belongs to the field of safety maintenance of natural gas pipelines, and relates to a detection and pumping treatment system for the deposition, attachment position and cumulative amount of lubricating oil in natural gas pipelines. Background technique [0002] In recent years, in order to meet the needs, the scale of my country's oil and gas pipeline network has continued to expand, and the level of pipeline construction and management has been greatly improved. According to the "Medium and Long-Term Oil and Gas Pipeline Network Planning", the scale of the national long-distance oil and gas pipeline network will reach 169,000 km by 2020; by 2025, the scale of the pipeline network will reach 240,000 km. 131,400 km, including about 72,600 km of natural gas pipelines, 30,900 km of crude oil pipelines, and 27,900 km of refined oil pipelines. [0003] With the implementation of the clean energy strategy, the consumption of natural gas in my ...

Problems solved by technology

The first idea is the following two patents (application number: CN201610111812.2, CN201510386095.X), one is to reduce deposition by improving the liquid carrying capacity through the gas vortex effect, this scheme does not fundamentally reduce the liquid accumulation in natural gas, And it can only treat the water in the gas; the other is to remove the effusion by gas lift, which has a small processing capacity and is easy to leak and pollute the environment

The second idea, such as the patent (application number: CN201920883923.4), installs a removal device between the air inlet and outlet, so that the accumulated liquid accumulates in the lower part of the device. This solution destroys the integrity of the pipeline, the processing capacity is small, and it is easy to leak and cause pollution.

Wireless transmission is less stable than wired, fully automatic control is less secure than manual, and manual control is less efficient than automatic control
