Embodiment Construction
[0024] See attached figure 1 , a two-stage pipeline type gas-liquid cyclone separator, the separator is mainly composed of two parts, the first-stage separation module I and the second-stage separation module II, the two-stage separation module passes through the front flange 7 in the middle of the separator and the rear method Lan 8 for connection; Among them, the primary separation module I is mainly composed of the axial inlet 3, the primary guide vane 4, the guide body 5, the sleeve 6, and the front liquid discharge pipe 17; the blade of the primary guide vane 4 is spiral, The outer edge and the inner edge are respectively connected with the inner wall of the first-level separation pipe (1) and the outer surface of the first-level guide body 5; the sleeve 6 is adjacent to the first-level guide vane 4 and connected with the tail of the blade; The barrel 6 is coaxial, extends horizontally inside the sleeve 6 and forms an annular cavity with the sleeve 6 . A front drain pipe...

A two-stage pipeline type gas-liquid cyclone separator is mainly composed of a first-stage separation module and a second-stage separation module; and the first-stage separation module is mainly composed of an axial inlet, a first-stage guide vane, a flow guider, a sleeve and a front liquid discharging tube. The sleeve is connected with the tail of the first-stage guide vane, and forms an annular cavity together with the first-stage separation tube and the flow guider; and the second-stage separation module is connected with the first-stage separation module through a middle part flange, and is mainly composed of the annular plate, a second-stage guide vane, an inner cylinder, an outlet diverging segment, a rectifying device, a rear liquid discharging tube and an axial outlet. The inner cylinder is fixed in the second-stage separation tube through the annular plate, the second-stage guide vane is arranged in the inner cylinder, the wall surface of the inner cylinder is provided with a spiral bar-shaped groove, and the tail part of the inner tube and the outlet diverging segment form the annular outlet. The separator integrally has a tubular structure, has a small size, and is easy to mount a pipeline; two ends of the separator are provided with standard flanges, so the separator can be conveniently connected with and detached from the pipeline; and the separator adopting two-stage cyclone separation makes the liquid content of a separated gas low, and has a high separation efficiency.
Description
technical field [0001] The invention relates to a two-stage pipeline type gas-liquid cyclone separator, which is an online separator used for the separation of condensate in natural gas pipelines, and belongs to the technical field of multiphase separation of oil and gas gathering and transportation systems. Background technique [0002] With the continuous development of gas fields, a certain amount of condensate and liquid water will be carried in the produced gas. The existence of moisture in natural gas will cause damage to the gathering and transportation system: during the gathering and transportation of natural gas containing sour gas, acid is easily formed due to the existence of water, which corrodes pipelines and equipment; It is easy to form hydrates and block valves, pipelines and equipment; the existence of liquid in natural gas will also reduce the transmission capacity of pipelines and cause unnecessary power consumption. Therefore, the liquid components must...
