Gas-liquid rotary turbine separation device

Abstract

The invention relates to a gas-liquid rotary turbine separation device, which comprises a hollow shell arranged on a support and a rotating shaft which is fixed in the shell by a sealing and lubricating device, wherein one end of the rotating shaft extends out of the shell, and a separation rotor positioned on the middle part of an inner cavity of the shell is fixed to the other end of the rotating shaft; and a gas-liquid two-phase spray nozzle is formed at one end, which is adjacent to the separation rotor, of the shell. The gas-liquid rotary turbine separation device is characterized in that the separation rotor comprises a separation disc which is fixed to the rotating shaft and is provided with an annular liquid collecting tank and an annular air collecting cavity sequentially and axially; the liquid collecting tank is connected with a separation cone; the liquid collecting tank and the air collecting cavity are communicated with a liquid reverse action spray nozzle and an air reverse action spray nozzle; an annular partition plate is arranged between the liquid collecting tank and the air collecting cavity; and a liquid spiral case and an air spiral case which are partitioned by the partition plate are arranged on the middle part of the inner cavity of the shell axially side by side. The gas-liquid rotary turbine separation device has a reasonable structure, is novel in design, high in separation efficiency and convenient to disassemble and maintain and is arranged in an axial cordwood mode, and the floor space is reduced by reducing axial geometric dimensions.

Description

technical field [0001] The invention relates to a gas-liquid separation device, in particular to a gas-liquid rotating turbine separation device, and 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 development of my country's oil and gas industry, especially the development of offshore oil and gas fields, oil and gas separators have developed from the traditional gravity type to the direction of high efficiency, compactness and energy saving. China's small se...

[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
