Problems solved by technology

The main problem is that the sampling port is directly facing the gas-liquid flow, which may easily cause the sampling port to be blocked
In addition, it is difficult to keep the distribution ratio constant due to the difficulty in satisfying the equal kinetic energy sampling conditions
In addition, the theoretical distribution ratio is fixed, and the distribution ratio cannot be adjusted at any time according to changes in upstream flow conditions

Abstract

A gas-liquid two-phase flow sampler with variable ratios belongs to the field of fluid distribution. A gas-liquid two-phase flow uniform distributor mainly comprises a diversion pipe, a fixed distribution chamber, a rotary distribution chamber, a current rectifier and a differential pressure gauge, wherein diversion grooves are uniformly formed in the circumferential direction of the diversion pipe; a two-phase fluid is uniformly diverted through the diversion grooves formed in a pipe wall to enter the fixed distribution chamber and the rotary distribution chamber respectively. Flow characteristics of all diversion ports can be guaranteed to be identical through flow pattern adjustment and resistance regulation of an entrance. By adjusting the lengths of the diversion grooves at the upstream of the rotary distribution chamber, a distribution ratio can be regulated in the range of 0-100%. Compared with a current gas-liquid two-phase fluid sampling device, the gas-liquid two-phase flow uniform distributor has the advantages that the size is small, the structure is compact, the distribution ratio can be randomly adjusted, and a sampling fluid and a main fluid have the same gas-liquid components and are not affected by parameters such as flow velocities and flow patterns of a gas-liquid phase of the entrance.

Description

technical field [0001] The invention belongs to the field of fluid distribution, in particular to a gas-liquid two-phase flow uniform distributor with adjustable distribution ratio. Background technique [0002] Gas-liquid two-phase flow widely exists in many industrial fields such as petroleum, chemical industry and nuclear energy. In a gas-liquid two-phase flow system, it is usually necessary to separate the gas-liquid two-phase flow into two streams. T-shaped tee and Y-shaped tee are the most common fluid distribution devices. However, when the gas-liquid two-phase flow passes through the tee, the ratio of the gas-liquid phase entering the two downstream branches of the tee is often the same as the gas-liquid phase in the upstream main pipeline. The composition is different, which is the so-called gas-liquid phase separation phenomenon. Many experimental studies have shown that the sampling characteristics of gas-liquid two-phase flow not only depend on the distributor ...
