Description

TECHNICAL FIELD

[0001] The utility model mainly relates to pipeline detection technical field, concretely relates to a chemical industry pipeline leak automatic detection device. BACKGROUND

[0002] In modern chemical industry, chemical industry pipeline as the key infrastructure connecting various production links, conveying various fluid materials, is widely used in petroleum chemical industry, natural gas, fine chemical industry and many other fields. These pipelines are running under complex conditions such as high temperature, high pressure and strong corrosion for a long time, combined with the influence of pipeline aging, external force impact, installation defects and other factors, pipeline leakage accidents occur from time to time.

[0003] Pipeline leakage not only leads to material waste, causing huge economic losses, but also may cause fire, explosion, poisoning and other serious safety accidents, posing a great threat to personnel life safety and ecological environment. For example, the leakage of toxic and harmful chemical substances will pollute the soil, water and air, and destroy the ecological balance; the leakage of flammable and explosive substances is easy to cause violent explosion when encountering fire source, causing heavy casualties and property losses.

[0004] At present, for the detection and treatment of chemical industry pipeline leakage, the traditional method mainly relies on manual inspection and some simple detection equipment. Manual inspection has problems such as low efficiency, high labor intensity, and detection results are greatly affected by human factors, which is difficult to realize real-time and comprehensive monitoring of the pipeline, and is easy to cause the leakage point to be found not in time, delaying the best treatment opportunity. Some early detection equipment, such as simple pressure sensor, flow monitoring device, etc., has limited detection accuracy and cannot accurately locate the small leakage point, and has single function, which can only complete the leakage detection, and the leakage treatment after leakage still needs manual operation, which not only consumes time and effort, but also carries out manual leakage plugging in high-risk environment, and the operator faces great safety risk.

[0005] In addition, some existing pipeline plugging technologies, such as traditional repair welding, punching and other methods, have high requirements for pipeline leakage environment and conditions, which are difficult to implement under some special conditions (such as pressure, high temperature, strong corrosion, etc.), and the plugging effect is unstable, which is easy to cause secondary leakage. With the rapid development of chemical industry, higher requirements for the automation, efficiency, safety and reliability of pipeline leakage detection and treatment are put forward.
