Problems solved by technology

However, due to the influence of gas-liquid coupling, liquid extraction resistance, and the volume of the separation device, it is very difficult to achieve low-cost, high-efficiency gas-liquid two-phase separation, and the applicable gas-liquid ratio range of each separation device is small

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1a and Figure 1b As shown, a horizontal pipeline type gas-liquid separation device of the present invention includes a main road pipe 1 arranged in a horizontal manner. The left and right sides are respectively provided with a tangential air guide channel 3 and a tangential liquid intake channel 4 along the axial direction, and a liquid intake boss 5 is designed at the bottom of the pipe section where the tangential air guide channel 3 is located. Downstream of the channel 3 and the tangential liquid extraction channel 4 is the gas phase outlet pipe 10; the liquid collection chamber 8 is connected below the main pipe 1, vertically downward, and the liquid collection chamber 8 passes through the tangential guide flow channel 3 and the tangential liquid extraction flow The channel 4 communicates with the left and r...

Abstract

The invention discloses a horizontal pipeline type gas-liquid separation device and method; a gas-liquid two-phase fluid is subjected to phase separation after being swirled by a swirling device in amain pipeline, a liquid phase and a gas phase are changed into a liquid film-gas core flow pattern under the action of centrifugal force, and the liquid film and a gas core both rotationally flow in apipeline; when two phases of the liquid film and the gas core flow into a separation section structure, the liquid film and a small amount of carrying gas are guided out of the main pipeline througha tangential liquid taking flow channel to enter a liquid collecting cavity; the carried gas flows around a middle partition plate in the liquid collecting cavity and then tangentially flows into thefluid of the main pipeline from the other side to a gas guide flow channel. The two flow channels are tangent to the rotational flow direction of the fluid in the pipe, so that the flow resistance forleading out the liquid film is relatively small, meanwhile, the disturbance to the gas core in the main pipe is extremely small, and the disturbance of the gas to the liquid film layer and the secondary carrying of liquid drops are reduced; the pipeline is horizontally arranged, so that the influence of gravity on the export of the viscous sub-layer of the liquid film is increased, the separationefficiency of the gas-liquid separation device is greatly improved, and the gas-liquid separation device is wide in applicable gas-liquid range.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid two-phase fluid separation, and in particular relates to a horizontal tube type gas-liquid separation device and method. Background technique [0002] In petroleum, chemical and other industrial production fields, fluids with different dryness will directly affect production efficiency. Therefore, the gas-liquid separation technology that realizes the efficient separation of gas-liquid two-phase fluids on-line in pipelines is not only widely used, but also very important. The mechanism of gas-liquid separation technology includes gravity sedimentation, centrifugal separation, filtration separation, inertial separation, etc. Traditional separation technology mainly relies on gravity sedimentation and centrifugal separation. The three-phase separator is a typical separation device that uses the principle of gravity sedimentation to separate gas and liquid. Its advantages such as simple structure...
