Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] like figure 1 shown, see also figure 2 , the embodiment of the present invention provides a pipeline pulse flow generator, the pipeline pulse flow generator includes: an input pipeline 1, a resonance cavity 2, a resonant shrapnel 24 and an output pipeline 3, the input pipeline 1 and the resonance The inlet 21 of the cavity 2 communicates, and the output pipe 3 communicates with the outlet 22 of the resonance cavity 2. A cavity 23 is arranged in the resonance cavity 2, and the cross section of the cavity 23 is from the inlet 21 to the outlet 22 first increases and then decreases, the periphery of the inlet 21 and the periphery of the outlet 22 are both axially provided with a plurality of resonant shrapnel 24, and the resonant ...

The invention discloses a pipeline pulse flow generator, comprising: an input pipeline, a resonant cavity, resonant shrapnel and an output pipeline, the input pipeline communicates with the inlet of the resonant cavity, the output pipeline communicates with the outlet of the resonant cavity, and the resonant cavity A cavity is provided, and the cross section of the cavity first increases and then decreases from the entrance to the exit. The periphery of the entrance and the periphery of the exit are both provided with a plurality of resonant shrapnel along the axial direction. The resonant shrapnel is located inside the cavity, and the resonance shrapnel and the hollow The cavities collectively serve to form a pulsating flow of fluid therethrough. In the present invention, by setting a cavity whose cross-section first increases and then decreases, the passing fluid forms a pulse flow. In addition to strengthening the formation of the pulse flow, multiple resonant shrapnels also form constraints and guide the direction of cleaning ball movement, making it It passes smoothly from the entrance to the exit, thereby enabling the pigging operation of the entire gathering and transportation pipeline to proceed smoothly and reducing cleaning costs; the structure of the pulse flow formed by the present invention is simple, small in size, and easy to manufacture and install.
Description
technical field [0001] The invention relates to the field of petroleum and natural gas, in particular to a pipeline pulse flow generator. Background technique [0002] In the process of oil and gas pipeline gathering and transportation, the cost of oil and natural gas gathering and transportation is increased due to factors such as large resistance loss and high energy consumption. Studies have shown that the use of pulse flow can greatly reduce the resistance loss in the process of oil and gas gathering and transportation. The pulser can convert the oil and gas continuous fluid into a pulse flow without any additional auxiliary devices, thereby improving the flow characteristics of the boundary layer, reducing the resistance during oil and gas gathering and transportation, reducing energy consumption, and improving the process of crude oil gathering and transportation Problems such as paraffin scaling. [0003] In the currently used pipeline pulse flow generator, in order ...
