Problems solved by technology

If oil spills cannot be recovered and disposed of quickly, it will seriously endanger the ecological environment on which human beings depend, and will have a series of serious impacts on water pollution prevention and control, soil and site treatment and restoration, and will also bring disasters to rescuers. Security risks
[0003] However, if the oil pipeline in operation suddenly leaks and is damaged, it is difficult to stop the transmission and reduce the pressure immediately, and it is impossible to take emergency measures to implement permanent repair in a short time, which causes the leakage from the exposed oil pipeline to the The gap for permanent repair of oil pipeline leaks, the possibility of oil hazards near the exposed oil pipeline leaks rises sharply
In the long-term pipeline emergency management process, there is a lack of more rigorous disposal experience and methods for the recovery of leaked oil products
[0004] In addition, the refined oil pipeline is different from the crude oil pipeline, not only its working pressure is high, but also because the fluidity, volatility, flammability and explosiveness of refined oil are higher than that of crude oil, so once a pipeline leakage accident occurs, the harm If there is no effective control and plugging means in a short period of time after the leakage accident occurs, the possibility of secondary disasters such as fire, explosion and environmental pollution caused by a large amount of leakage of refined oil is extremely high
However, due to the particularity of refined oil, the post-leakage control and plugging technology is very different from the emergency repair technology for crude oil pipeline leakage. It cannot be directly drained and blocked. The leakage of refined oil must be controlled first and then blocked. Is it effective? , Safe control of leakage is the first and key of emergency repairs, of course reliable drainage equipment is required

Abstract

The invention provides a drainage device for emergency disposal of oil pipeline leakage caused by third-party damage. The drainage device comprises a drainage sleeve connecting pipe(1), a drainage pipe connector(2) and a drainage main pipe(3). A leakage point of the oil product pipeline(7) is wrapped by the drainage sleeve connection pipe(1). The drainage pipe connector(2) is connected to the drainage sleeve connecting pipe(1). The interior of the drainage pipe connector(2) is connected with the drainage sleeve connecting pipe(1) through a drainage channel (10). The drainage main pipe(3) is communicated with the other end of the drainage pipe connector(2). A sealing sensor is arranged in the drainage sleeve connecting pipe(1). According to the drainage device, the overall strength is high,the structure is stable, the sealing and drainage effects is good, and emergency disposal can be safely and effectively carried out on oil pipeline leakage which is damaged by the third party, so that the safety of the surrounding environment and the treatment personnel is guaranteed. The invention belongs to the advanced environment-friendly industry.

Description

technical field [0001] The invention belongs to the advanced environmental protection industry, and relates to the technical field of water pollution prevention, soil and site treatment and restoration caused by oil pipeline leakage damaged by a third party, and specifically relates to an oil pipeline leakage damaged by a third party Drainage device for emergency treatment. Background technique [0002] In recent years, with the rapid economic development, the demand for energy has been increasing. In the process of crude oil extraction, transportation and refining, with the continuous increase in the construction and operation mileage of oil pipelines, the probability of exposed oil pipelines being damaged by third parties increases, and the probability of oil spill pollution incidents increases. If oil spills cannot be recovered and disposed of quickly, it will seriously endanger the ecological environment on which human beings depend, and will have a series of serious im...
