Gas-liquid two-phase flow distributor and gas-liquid two-phase flow distribution method

Abstract

The invention discloses a gas-liquid two-phase flow distributor and a gas-liquid two-phase flow distribution method. The distributor is provided with a mixing pipe (1). A spiral plate (3) and a throttling orifice plate (2) are arranged in the mixing pipe. An outlet of the mixing pipe is communicated with an inner cavity of a perforated cylinder (7); and the perforated cylinder is arranged in an inner cavity of a distribution cavity cylinder (6). A rotating shaft (15) is arranged on the rotating plate (10). A fixed partition plate (8) is arranged on the inner surface of the distribution cavitycylinder, and a rotating partition plate (9) is arranged on the outer surface of the perforated cylinder (7). A first distribution cavity outlet pipe (11) is communicated with a first distribution cavity (16), and a second distribution cavity outlet pipe (12) is communicated with a second distribution cavity (17). The invention further discloses the gas-liquid two-phase flow distribution method using the gas-liquid two-phase flow distributor. The distributor and the method can be used in the fields of petroleum, chemical industry, nuclear industry and the like, and realize accurate distribution of gas-liquid two-phase flow in proportion.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid two-phase flow and fluid distribution, and relates to a gas-liquid two-phase flow distributor and a gas-liquid two-phase flow distribution method. Background technique [0002] The flow patterns of gas-liquid two-phase flow are many and not uniform, and various flow patterns will appear under different gas-liquid flow rates. Under certain flow patterns, especially in the slug flow pattern, the pressure and gas-liquid flow at each section of the pipeline often fluctuate violently. Strictly speaking, the gas-liquid two-phase flow pipeline is always in an unstable flow state. [0003] In different industrial fields such as petroleum, chemical industry, and nuclear industry, there are corresponding applications for the proportional distribution of gas-liquid two-phase flow and uniform sampling operations. The proportional distribution of gas-liquid two-phase flow is more difficult than the propor...
