Gas vane type gas-liquid rotary turbine separation device

Abstract

The invention discloses a gas-vane type gas-liquid rotating turbine separating device. The separating device comprises a hollow shell mounted on a bracket, and a rotating shaft fixed in the shell through a sealing and lubricating device, wherein one end of the rotating shaft extends out of the shell, and a separating rotor positioned in the middle of an inner cavity of the shell is fixed at the other end of the rotating shaft; one end of the shell adjacent to the separating rotor is provided with a gas-liquid two-phase nozzle; the separating rotor comprises a separating disc fixed on the rotating shaft, wherein an annular liquid collecting tank and an annular gas collecting cavity are axially arranged on the separating disc in order; the liquid collecting tank is connected with a separating cone and communicated with a liquid retroaction nozzle; a circle of gas vanes communicated with the gas collecting cavity surround the periphery at the bottom of the gas collecting cavity, and an annular separating board is arranged between the liquid collecting tank and the gas collecting cavity; and a liquid volute and a gas volute which are separated by a separating board are axially arranged at the middle part of the inner cavity of the shell in parallel. The gas-vane type gas-liquid rotating turbine separating device is reasonable in structure, novel in design, high in separation efficiency, and convenient in demounting and maintenance due to axial cordwood system arrangement; and since the axial geometric size is reduced, the floor space of the separating device is reduced.

Description

technical field [0001] The invention relates to a gas-liquid separation device, in particular to a gas-blade type gas-liquid rotary turbine separation device, which belongs to the technical field of oil-gas separation and natural gas dehydration in oil-gas gathering and transportation systems. Background technique [0002] In the petroleum industry, the traditional gas-liquid two-phase separation technology has been well developed, but there are three main problems: one is that the traditional separation equipment is bulky and heavy; the other is that the useful energy in the multiphase fluid is partially or completely consumed; the third is that when foam and emulsification are produced, the separation is not complete. With the continuous development of my country's oil and gas industry, especially the development of offshore oil and gas fields for the development of oil and gas industry requirements, oil and gas separators have developed from the traditional gravity type t...

Problems solved by technology

[0002] In the petroleum industry, the traditional gas-liquid two-phase separation technology has been well developed, but there are three main problems: one is that the traditional separation equipment is bulky and heavy; the other is that the useful energy in the multiphase fluid is partially or completely consumed; the third is that when foam and emulsification are produced, the separation is not complete

[0004] The pressure energy conversion device in the hybrid two-phase turbine in the Hays patent - the gas-liquid two-phase nozzle, is realized by an irregular flow channel with an adjustable throat cross-sectional area. Although it can achieve a certain degree of flow regulation, it cannot guarantee the fluid Efficient use of pressure energy; the separated liquid film is always in contact with the gas, which is not conducive to reducing the secondary mixing; the gas blades of the separator adopt axial blades, the overall length is large, and the floor area is large
