Description

A rapid plugging method for plugging the air bag outside the leakage of the risk source pipeline

technical field

The invention relates to a pipeline leakage sealing device and a sealing method thereof, in particular to a risk source pipeline leakage external sealing air bag and a rapid sealing method thereof. It is used for sealing pipeline leakage in the process of petrochemical, coal chemical production, toxic gas and liquid production and storage and transportation, and can also be used for pipeline sealing in gas, heat and water supply emergency.

Background technique

Pipeline leakage often occurs. On July 7, 2000, a major poisonous gas leakage accident occurred in Chengdu-Chongqing Expressway. Due to the lack of corresponding sealing equipment and corresponding sealing methods, a large amount of poisonous gas leaked and poisoned many firefighters. On March 29, 2005, liquid chlorine leaked from the Huaian section of the Beijing-Shanghai Expressway; on August 18, 2009, Chongqing styrene poisonous gas leaked; on August 5, 2009, ammonia gas leaked in Chifeng, Inner Mongolia, also because there was no corresponding sealing device And the corresponding plugging method has caused great economic loss.

With the rapid development of industry, the economic loss caused by leakage is also becoming more and more serious. In the world, about 4 billion tons of dangerous substances are produced every year. There is a huge potential danger in the storage and transportation of these substances. Because of the leakage, not only the energy and materials are continuously lost, but also the toxic and harmful , Corrosive, flammable, explosive, high temperature, high pressure various liquid media are constantly leaking. As a result, it will cause environmental pollution, cause fire, explosion, poisoning and personal injury and death accidents. An enterprise often stops production of the entire production system because of a small leak. At this time, people began to notice the practical value of quickly establishing a blocking emergency device in an emergency.

There is no corresponding pipeline sealing device and sealing method for existing pipeline leakage. The main sealing device and disposal method are to use different shapes of plugging pads, plugging wedges, plugging glue, plugging tape and other plugging materials. Plugging; micropore leakage is blocked by screwing and adhesive into the hole; leakage of pressurized pipeline is plugged by bundling air, or using rubber plate and strapping tape, or using metal shell lined with rubber pad, etc. Blocking with special equipment,

The above-mentioned different plugging devices and plugging methods for different existing pipeline leakage are inconvenient in actual use, the scope of application is relatively limited, the operation is relatively complicated, and it cannot be quickly and effectively plugged and eliminated. There are high professional requirements for operators.
