Description
Technical Field
The invention relates to a pipe cleaner for cleaning deposits in a natural gas pipeline, in particular to a jet flow pipe cleaner with a rotary steel brush.
Background
Because of the different selection of the transportation process and the difference of the gas quality treatment level and the like, the natural gas gathering and transportation pipeline or the long transportation pipeline inevitably generates physical or chemical action in the natural gas transportation process, so that sediments such as condensate, oil stain, medicament residue, dust and the like are generated in the pipeline, and the pipeline wall is corroded to form iron sulfide and iron oxide, so that the sediments in the pipeline are further increased, the pipeline transportation efficiency is reduced, the energy consumption is increased, and the risk is caused to the safe operation of the pipeline.
The regular pigging of the natural gas conveying pipeline is an important link of daily production activities of pipeline enterprises and is also a link with great safety risk. When the pipeline topography is large, the amount of sediment in the pipeline is large, the sediment shape is complex, and the like, the damage and blockage of the pipeline cleaner occur sometimes. When the pipe cleaner is damaged or blocked, the pipe cleaner can only be replaced or unblocked in a pipe cutting mode, and the mode causes great consumption of operation cost and great hidden danger of pipeline repair. In addition, in the overall implementation process of pipeline integrity management, the internal detection and evaluation of the pipeline is a key link, the requirement of the internal detection activity on the pipeline environment is harsh, and before the internal detection activity, the pipeline needs to be subjected to multi-round combined pipeline cleaning operation of various types of pipeline cleaners, so that the pipeline cleanliness is improved, and the requirement of the internal detection of the pipeline implementation is met. Generally, the pigging operation is a periodically necessary operation in the oil and gas pipeline transportation process, and the characteristic of easy loss of the pig causes the pigging operation cost to be high, and a greater safety risk exists in the pigging implementation process.
At present, the front end and the rear end of a traditional type pipe cleaner are closed, and the pipe cleaner is pushed to advance in a pipeline mainly by the aid of pressure difference formed by a conveying medium in the front and the rear of the pipe cleaner, so that deposits at the front end and the pipe wall of the pipe cleaner can be cleaned. According to the different form with the pipeline seal, can divide into spherical pig, leather cup shape pig, straight plate shape pig etc. with traditional pig. The traditional pipe cleaner has a simple structure and is easy to process, but the application process has a larger problem. The front and the back of the pipe cleaning process are closed, the running speed of the pipe cleaner is difficult to control due to the change of the pressure difference between the front and the back of the pipe cleaner, so that the friction between the pipe cleaner and a pipeline is intensified, and the pipe cleaning effect is difficult to ensure; deposits are easy to accumulate, and pipelines are easy to block, so that the pipeline cleaning fails; because the pigging effect of single pig is limited, need multiple pig combination to carry out the pipeline cleaning operation usually, this operational procedure is loaded down with trivial details, clears away with high costs and efficiency not high. In view of the limitations of the traditional type of pig, the current jet type pig has received attention from some scholars and institutions both at home and abroad. The jet type pipe cleaner penetrates through a jet channel in the pipe cleaner, and high-speed jet is formed by means of pushing pressure of a conveying medium at the rear end of the pipe cleaner, so that deposits on the wall surface of a pipeline are efficiently cleaned, the flowing form of the deposits at the front end of the pipe cleaner is changed, and the deposits at the front end of the pipe cleaner are prevented from being accumulated. The jet type pipe cleaner is mainly developed for cleaning natural gas liquid accumulation pipelines, and particularly has a good application prospect when the jet type pipe cleaner is used for large-drop fluctuating liquid accumulation pipelines. However, jet-type pigs are not suitable for cleaning pipes where solid deposits and dense pipe wall accretions formed by corrosion are the main deposits.
Therefore, how to design a cleaning device having the dual functions of powerful cleaning of pipe wall and jet flow, so as to be suitable for cleaning pipe wall deposits with various adhesion forms has become one of the important issues to be solved in the field.

The front supporting plate 4 and the rear supporting plate 5 can be in a disc shape and can be made of metal materials, the front port and the rear port of the tube body 1 are respectively covered by the front supporting plate 4 and the rear supporting plate 5, and the opposite annular surfaces (namely the parts outside the tube body) of the front supporting plate 4 and the rear supporting plate 5 are respectively abutted to the front end of the at least one front sealing leather cup 2 and the rear end of the at least one rear sealing leather cup 3. The front clamping flange 6 and the rear clamping flange 7 are sleeved on the pipe body 1 and respectively abut against the rear end of the at least one front sealing cup 2 and the front end of the at least one rear sealing cup 3, so that the at least one front sealing cup 2 and the at least one rear sealing cup 3 are respectively clamped and fixed between the front supporting plate 4 and the front clamping flange 6 and between the rear supporting plate 5 and the rear clamping flange 7. The middle part of the front supporting plate 4 is provided with a circular through hole 41 communicated with the inside of the tube body 1. Referring to fig. 2, the rear support plate 5 has a plurality of through holes 51 communicating with the inside of the tube body 1, and a fixing shaft 52 is formed at the middle portion of the rear support plate 5 extending along the axis of the tube body 1 toward the front support plate 4, the fixing shaft 52 penetrates through the circular through hole 41, and a bearing 53 is mounted on a portion of the fixing shaft 52 outside the circular through hole 41. As shown in fig. 3, a through hole (not shown) is formed in the middle of the rotary impeller 9, a circular air inlet 91 is formed in one side surface of the rotary impeller 9, a plurality of arc-shaped air passages 92 which are communicated with the air inlet 91 and radially distributed are formed in the rotary impeller 9, and air outlet holes 93 which are communicated with the outside are formed in the end portions of the arc-shaped air passages 92 far away from the center of the rotary impeller 9. The rim of the steel brush disk 8 has a steel brush 81, the middle portion of the steel brush disk 8 also has a through hole (not labeled), the steel brush disk 8 is fixedly installed on the side surface of the rotating impeller 9 not provided with the air inlet 91, the installation mode can be integrated with the rotating impeller, or can be fixed on the rotating impeller by a fastening member such as a bolt, and the through hole of the steel brush disk 8 is aligned with the through hole of the rotating impeller 9. The air inlet 91 of the rotary impeller 9 is coaxially opposed to the circular through hole 41 of the front support plate 4, and the through hole of the rotary impeller 9 and the through hole of the steel brush disk 8 are fitted and fixed to the bearing 53. And the end of the fixed shaft 52 passes through the through hole of the rotary impeller 9 and the through hole of the steel brush disc 8 and then is fixedly combined with the middle part of the side surface of the propulsion plate 10, thereby forming the jet flow cleaning device. When the jet flow pipe cleaner cleans sediments in a natural gas conveying pipeline, a conveying medium (natural gas) pushes an airtight component (a sealing leather cup) of the jet flow pipe cleaner to push the jet flow pipe cleaner forwards, and a pushing plate pushes the sediments to move forwards. Meanwhile, the conveying medium enters a plurality of arc air passages 92 inside the rotary impeller 9 through the through holes 51 on the rear supporting plate 5 through the pipe body 1, the circular through holes 41 of the front supporting plate 4 and the air inlet 91 so that the rotary impeller 9 drives the steel brush disc 8 to rotate to clean the attached sediments on the pipe wall, and the conveying medium is ejected through the air outlet 93 to form jet flow so as to clean and blow the sediments in front of the steel brush disc 8, so that the jet flow pipe cleaner has the double effects of powerful pipe wall cleaning and jet flow.
More specifically, as shown in fig. 3, the air inlet 91 is circular and is opened in the middle of one side surface of the rotary impeller 9 and does not penetrate the other side surface of the rotary impeller 9. The through hole of the rotary impeller 9 is formed on the other side surface of the rotary impeller 9 coaxially with the air inlet 91. The diameter of the air inlet 91 is larger than the diameter of the perforations of the rotating impeller 9. A tubular perforated portion 94 is formed in the perforation of the rotary impeller 9 so as to extend in the direction of the air inlet 91 at the hole edge, and as shown in fig. 1, the perforated portion 94 is fixed to the bearing 53 in a sleeved manner. Thus, the air inlet 91 can introduce the conveying medium into the rotating impeller 9, so that the rotating impeller 9 rotates under the reaction force of the arc-shaped air channel 92 to the conveying medium; further, since the through hole 94 is fixed to the bearing 53, the stability of the coupling between the rotary impeller 9 and the bearing 53 can be improved, and the stable rotation of the rotary impeller 9 can be ensured. The curved degrees of the plurality of arc air passages 92 are the same, and the plurality of arc air passages 92 are uniformly distributed inside the rotary impeller 9 in a clockwise or counterclockwise direction, and a plurality of air outlets 93 are formed in the periphery of the rotary impeller 9.
