Problems solved by technology

However, when the liquid transported by the pipeline contains solid particles, because the solid particles will settle in the pipeline, the solid particles will contact the inner wall of the pipeline, resulting in frictional resistance, which consumes the transportation energy, and after the pipeline reaches a certain distance, the solid particles in the pipeline will Will stop moving and settle down, so that the effective distance of pipeline transportation reaches the limit
[0003] For example, in the civil engineering of land reclamation, high-pressure pumps are used to transport sandy-soil liquid-solid mixture materials to long-distance places. In the delivery pipe, sand particles sink under the action of gravity and contact with the inner wall of the pipe to generate greater frictional resistance. Consumes a large amount of transportation energy, so that after the pipeline transportation reaches a certain distance, the solid particles of sand and soil in the pipe will stop moving and settle down, reducing the efficiency of pipeline transportation and shortening the limit transportation distance

Embodiment 1

[0026] see Figure 1-3 One or more small pipes 3 are installed in the delivery pipe 1, and the small pipes 3 are provided with a joint 2 for high-pressure gas or water, through which the joint 2 is connected to input high-pressure gas or water 6, and small pipes 3 are provided with small pipes at a certain distance. Hole 4 through which high-pressure gas or water 7 is injected, and the injected high-pressure gas or water 7 causes the solid particles in the liquid-solid mixture material transported in the pipeline to be disturbed by power and cannot be deposited, so that the liquid in the pipeline are piped to greater distances.

[0027] This method is adopted: (1) The processing and manufacturing method of the small pipeline 3 for conveying high-pressure gas or water: the material is a seamless steel pipe with an inner diameter of Φ25-Φ40 (less than 1 / 20 times the inner diameter of the conveying pipe) and a wall thickness of 3mm-3.5mm. Small steel pipes, the length of every s...

Embodiment 2

[0030] see Figure 4-6 One or more corrugated hoses 9 are installed in the delivery pipe 1, and the corrugated hoses 9 are expanded and contracted by intermittently pressurizing and depressurizing the corrugated hoses 9, and the expansion and contraction of the corrugated hoses 9 are carried out alternately , so that the solid particles in the liquid-solid mixture transported in the pipeline are disturbed by dynamic force and cannot be deposited, so that the liquid in the pipeline is transported to a longer distance by the pipeline.

[0031] Using this method: (1) The material of the corrugated hose is a flexible hose with an inner diameter of Φ40~Φ50 (less than 1 / 15 times the inner diameter of the delivery pipe), and the length of each section of the hose can be 10 to 10 times the length of the delivery pipe section. 15 times. (2) Calculate the starting position of the corrugated hose: if the normal delivery distance of the delivery pump for the sand and soil liquid is N kil...

[0034] see Figure 7-9 A vortex generator 10 is connected and installed on the conveying pipe. Through the disturbance of the spiral force generated by the vortex generator 10, the liquid-solid mixture material flows in a spiral manner, thereby improving the efficiency of the pipeline conveying materials and extending the limit conveying distance.

[0035] Adopt this method: (1) manufacture the vortex generator 10, the vortex generator is formed by the fitting of two pipes with the same length and different pipe diameters—the inner pipe 10a and the outer pipe 10b, and the two ends are respectively welded to the flange as a whole, The inner pipe is installed with a nozzle 11 every certain distance along the circumference, the angle between the outlet direction of the nozzle 11 and the liquid flow direction is 15-20 degrees, and then rotated 15-20 degrees along the horizontal direction; the inner diameter of the inner pipe 10a and the inner diameter of the delivery pipe 1 The sa...

Abstract

The invention relates to a cleanup method for pipeline transport, which prevents the solid grains in the liquid and solid mix material from sedimentation and stops the occurrence of the shift through imposing the momentum disturbance to the liquid and solid mix material transported inside the pipeline, so as to improve the transport efficiency of the pipeline and to prolong the limit delivery distance. Preferentially, at least a small pipeline is arranged inside a delivery pipe, a plurality of small holes are interval arranged on the small pipelines in a certain distance, the high pressure gas or the water are projected through the small holes on the small pipelines. Preferentially, at least a corrugated hose is axially arranged inside the delivery pipe, the corrugated hoses are discontinuously pressurized and pressure released so as to cause the corrugated hoses to inflate and shrink. Preferentially, at least a vortex generator is axially arranged on the delivery pipe, which producesthe spire action force to cause the liquid and solid mix material to make spire type flowing.

Description

technical field [0001] The invention relates to a drainage aid method for pipeline transportation, in particular to a drainage aid method for exerting dynamic interference on liquid-solid mixed materials in the pipeline. Background technique [0002] Long-distance transportation of liquid substances by pipeline method is a common transportation method. However, when the liquid transported by the pipeline contains solid particles, because the solid particles will settle in the pipeline, the solid particles will contact the inner wall of the pipeline, resulting in frictional resistance, which consumes the transportation energy, and after the pipeline reaches a certain distance, the solid particles in the pipeline will It will stop moving and settle down, so that the effective distance transported by the pipeline reaches the limit. [0003] For example, in the civil engineering of land reclamation, high-pressure pumps are used to transport sandy-soil liquid-solid mixture mater...
