Efficient low-resistance separator for high-liquid-content gas-liquid two-phase flow

Abstract

The invention provides an efficient low-resistance separator for high-liquid-content gas-liquid two-phase flow, and belongs to the field of separators. The efficient low-resistance separator for the high-liquid-content air-liquid two-phase flow comprises a gas-liquid two-phase inlet, a gravity sedimentation chamber, a first-stage cyclone tube, a liquid collecting chamber, a liquid collecting chamber draining port, a second-stage cyclone tube, a gas exhausting port, an air exhausting chamber and the like, and is used for gas-liquid separation on high-liquid-content gas. According to the separator, an operation mode that the cyclone tubes at the same stage are connected in parallel and the cyclone tubes at different stages are connected in series is performed in one separator, namely, a plurality of cyclone tubes are connected in parallel to form a stage, and cyclone tubes at two stages are synchronously arranged, so that the separation efficiency is effectively improved while the processing capacity of the device is improved; in addition, the separator can be adapted to the working condition of high-liquid-content gas-liquid two-phase flow; two stages of guide blades connected in series are arranged in each cyclone tube at each stage, so that the separation capacity of the cyclone tubes at each stage can be improved; and meanwhile, the cyclone production synergistic effect between the two-stage guide blades connected in series can be realized, so that the resistance is low, and the requirements on pressure in a following process can be met.

Description

technical field [0001] The invention belongs to the field of gas-liquid separation equipment, and relates to a high-efficiency and low-resistance separator for high-liquid gas-liquid two-phase flow. Background technique [0002] Compared with fossil fuels such as petroleum and coal, natural gas has many advantages such as cleanness, convenience, high quality and high efficiency. Nowadays, natural gas is widely used in various industries and has strong market development potential. However, liquid water or condensate often appears in natural gas gathering and transportation pipelines, which will reduce the cross-sectional area and effective delivery capacity of the pipeline, and cause corrosion damage to the pipeline. Therefore, before long-distance transportation, natural gas should undergo gas-liquid separation to effectively remove the moisture in it. [0003] At present, traditional gas-liquid separation equipment is usually composed of multiple separation equipment. Th...

Problems solved by technology

Among them, the single-stage cyclone gas-liquid separator has poor separation effect on natural gas with high liquid content, while the combined cyclone and filter gas-liquid separator has good separation effect, but has disadvantages such as large pressure drop and frequent replacement of filter elements.
