Embodiment Construction

[0008] Describe an embodiment of the present invention below in conjunction with accompanying drawing.

[0009] figure 1 It is an axial-flow fluid vortex generator used in oil and gas pipelines. It includes: an inlet port (7), a casing (2), an outlet port (1), an inlet guide cone (6), a spiral blade (5), an intermediate body (4), and an outlet guide cone (3). The inlet end (7), the shell (2), and the outlet end (1) are welded into a pipeline. The inlet guide cone (6), the spiral blade (5), the intermediate body (4) and the outlet guide cone (3) in the casing (2) are welded into a combined device. The inner end of the spiral blade (5) is fixed on the intermediate body (4), and the outer end is fixed on the shell (2). When in use, the axial-flow fluid vortex generator is directly connected to the oil and gas pipeline, and an axial-flow fluid vortex generator is arranged every 3Km.

Abstract

The invention relates to a conveying device for the fluid of the mixture of oil and gas. The axial-flow fluid vortex generator used on oil and gas pipelines is formed by connecting an inlet end, a housing and an outlet end; a group of devices formed by connecting an inlet flow guiding cone, a helicallobe, a midbody and an outlet flow guiding cone are arranged in the housing; an inner end of the helicallobe is fixed on the midbody, and an outer end thereof is fixed on the housing. The invention ensures that the mixture fluid can flow in a pipeline in the modes of spiral and layering, so that compared with the traditional pure axial transmission, the deposition amount of paraffin and encrustment transmitted by the pipeline is decreased by more than 90%; meanwhile, the workload on cleaning paraffin precipitation sediment incrustation is reduced, the transmission kinetic energy loss is reduced, the transmission efficiency is improved, and the transmission cost is reduced. Meanwhile, the invention is also suitable for transmitting the mixture fluid in the fields of chemical engineering, medicine, food and the like.

Description

technical field [0001] The invention relates to a delivery device for oil-gas mixture fluid. Background technique [0002] Oil and gas transported through pipelines contain crude oil, natural gas, water and other substances, among which there are a large amount of paraffin and scale in the crude oil, these paraffin and scale will deposit on the inner wall of the pipeline during transportation, and after a certain period of time , the sediment will accumulate thicker and thicker, the effective diameter of the delivery pipeline will become smaller and smaller, and the delivery capacity of the pipeline will be greatly reduced. In order to enhance the conveying capacity, the traditional method is to regularly remove wax and scale from the pipeline by means of high-temperature steam dissolution or mechanical expansion. These methods have high work intensity and low removal efficiency. If it is not obvious, it will lead to an increase in the cost of oil and gas transportation. M...
