Description
Technical Field
The invention relates to the technical field of pipeline cleaning, in particular to a rotary jet flow pipe cleaner.
Background
In recent years, the demand of people for petroleum and natural gas is increasing day by day, so that the demand of oil and gas import in China is very large, at present, natural gas is imported mainly by virtue of pipelines and LNG, and the pipelines are widely applied to natural gas gathering and transportation. As the pipe runs, the inner wall of the pipe may adhere to a large amount of wax, deposits, dirt, and condensate. The effective sectional area of the pipeline is reduced due to the situations, the transportation of natural gas is influenced, and in severe cases, ice-like crystalline substances, namely natural gas hydrates, can be directly generated in the pipeline by the natural gas, so that a flow channel is gradually reduced and even blocked, and finally accidents are caused. Therefore, the pipe must be cleaned regularly to remove accumulated liquid in the pipe, reduce the total pressure drop and improve the conveying capacity.
The prior pipe cleaner generally arranges a leather cup or a ball body into a pipeline, and pushes the leather cup or the ball body to move in the pipeline by means of front-back pressure difference so as to clean the pipe. This kind of pig separates completely around, and the condition in the pipeline is complicated in reality, and differential pressure can't remain unchanged all the time around the pig, can accelerate for one time when differential pressure is too big can the pig functioning speed, and the unable deceleration of pig self under artificial supplementary does not have, can accelerate the wearing and tearing of pig leather cup like this, destroys the inner wall of pipeline even, shortens pipeline life. Simultaneously, because the pig can't carry out effectual processing to the front end condensate, a large amount of condensate gathering will probably appear for a long time when the pig operation, and this not only can strike the pig, causes the pig damage, still can cause the overload of trap to produce serious accident.
In order to solve the problems, the invention provides a rotary jet flow pipe cleaner.
Disclosure of Invention
In order to overcome the defects in the background art, the invention provides a rotary jet flow pipe cleaner.
