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.

A rotary jet flow pipe cleaner comprises a rotary jet flow part and a pipe cleaning part, wherein the rotary jet flow part comprises a jet flow disc, an end cover, a connecting shaft flange, a cleaning brush and a rotating shaft; the jet flow disc is fixed between the end cover and the connecting shaft flange, and the cleaning brush and the rotating shaft are arranged on the connecting shaft flange; the pipe cleaning part comprises a shell, a flow guide disc, a leather cup, an isolation flange, a baffle, a spring and a control valve; the leather cup, the flow guide disc, the isolation flange and the leather cup baffle are all fixed outside the shell, and the control valve is fixed inside the shell through a spring and the baffle; the rotary jet flow part and the cleaning pipe part are connected with a bearing end cover through a rotating shaft and a bearing.

Further, the jet flow dish is formed by two concatenations, it has half arc passageway and the cylindrical nozzle that revolves to opposite to be used for the concatenation to be complete jet flow passageway to process respectively above-mentioned, the cylindrical nozzle has the efflux basic section of broad to guarantee effectual jet width, simultaneously cylindrical nozzle exit velocity is lower, thereby pressure is higher prevents that outlet pressure decline from leading to the gas in pig the place ahead to strike the pig against the current, arc passageway can produce the rotatory power of drive jet flow dish after the fluid passes through, from the fluid that the nozzle passes through, the condensate liquid of the pig front end that the disturbance is gathered, and the reaction force that the efflux produced also can drive jet flow dish and rotate, the direction of rotation of jet flow dish is revolved to the direction decision of nozzle by the arc passageway that splices into, the change of two jet flow dish positions of accessible.

Furthermore, the rotating direction of the jet flow disk is the same as the screwing direction of the connecting shaft flange and the rotating shaft, so that the working process is ensured not to be loosened due to rotation.

Furthermore, one end design has the screw hole with the pivot assembly in the middle of the connecting shaft flange, and the other end design has cistern and drain hole to be used for holding and the output of foamer, and the drain hole realizes the intercommunication of cistern and cleaning brush.

Furthermore, when the control valve is blocked during the operation of the pipe cleaner, the shell stops moving, the control valve moves forwards to close the jet flow channel due to the action of inertia to overcome the action force of the spring, all energy used for jet flow is converted into the pressure difference between the front and the back of the pipe cleaner, the forward thrust of the pipe cleaner is increased, and the jet flow channel is opened again through the action of the spring and inertia after blocking is removed.

During the working process of the rotary jet flow pipe cleaner, fluid enters the rotary jet flow part after passing through a control valve of the pipe cleaning part, is sprayed out of a nozzle through an arc-shaped flow passage to disturb the condensate ahead, and simultaneously impacts scales on the lower portion of the pipe wall belt, the reaction force brought by the fluid drives the jet flow disc to rotate, the scales are further treated by the cleaning brush, the foaming agent flowing out of a liquid tank through a liquid guide hole enters the cleaning brush and finally is mixed into the condensate at the front end of the pipe cleaner to generate bubbles, and the damage of slug flow generated by condensate accumulation is reduced; the pipe cleaning part collects and transports cleaned scales by using a leather cup, and if blockage occurs in the operation process, the control valve moves forwards to close the jet flow channel and increase the forward thrust of the pipe cleaner to realize blockage removal.

The invention can effectively clean the pipeline by using the jet effect and the cleaning brush through the rotary jet, can reduce the harm of slug flow caused by the accumulation of condensate, can automatically remove the blockage after the blockage occurs, improves the reliability of the pipe cleaning operation and saves the maintenance cost of the pipeline.
