Gas-liquid diphasic fluid distributor

Abstract

The invention discloses a gas-liquid two-phase fluid distributor, wherein a main pipe is designed as an annular channel; a cross tee is arranged on the pipe for gas-liquid separation; a sieve tube is arranged inside the pipe; a corresponding annular liquid channel is arranged on the lower part of the pipe and is connected with manifold branches of a gas path through a communicating pipe; a plurality of liquid-phase branches are led out of the liquid channel and are mixed with the gas path; and flowmeters and adjusting valves are arranged on the liquid-phase branches and used for measuring and adjusting the liquid-phase flow rate. Gas-liquid two-phase fluid flowing into the pipe is separated into single-phase gas and single-phase liquid first, and then the single-phase gas and the single-phase liquid are separated into a plurality of branches for flowing respectively, and are remixed to ensure the dryness of mixture of the gas-liquid two-phase fluid obtained by each branch is consistent with that of an inlet of the main pipe, thereby realizing high-efficiency equal dryness distribution of the gas-liquid two-phase fluid and obviously increasing the flow rate of the inlet and the adaptation range of the dryness.

Description

technical field [0001] The invention relates to a fluid distributor, in particular to a gas-liquid two-phase fluid distributor. Background technique [0002] In engineering fields such as petroleum, chemical industry and energy power, it is often necessary to distribute the gas-liquid two-phase fluid into two or more branches. During the distribution process, it is always hoped that the two-phase fluid at the outlet of each branch has the same gas-liquid ratio. That is, the distribution of two-phase fluid is carried out according to the principle of equal dryness. Therefore, there is a need for a device for the control and measurement of the distribution of two-phase flow fluid in each branch. [0003] At present, the distributors used at home and abroad mainly include radial distributors, Splitigator distributors from Texaco, etc. The principle of the radial distributor is that the distribution branch pipes are radially arranged in geometric distribution, and the position...

Problems solved by technology

However, there is an obvious problem in this method, that is, the influence of the flow pattern of the fluid in the main pipeline on the separation efficiency is not considered. Therefore, in the case of annular flow in the main pipeline, it is obviously difficult to better separate the two-phase flow through the ordinary tee. Separated into a separate gas phase and liquid phase to flow separately, and due to the entrainment effect when the flow rate is high, part of the water enters the gas phase pipeline, the greater the flow rate of this part of water, the greater the impact on the distribution effect

[0004] To sum up, there are some problems in the distribution device at this stage: the method of directly distributing the two-phase fluid by the radial distributor can no longer meet the needs; single-phase fluid

Thereby existing technology can only be adapted to very little fluid velocity range
