Problems solved by technology

[0006] To sum up, the distributor with symmetrical distribution of branch pipes is difficult to meet the current production needs, and the distribution method of pre-intensified mixing or rectification is too narrow in application range, which is greatly restricted in engineering applications
Moreover, several types of distribution devices currently proposed cannot perform self-adaptive adjustments when the incoming flow or the pressure in some working areas fluctuate, resulting in changes in the flow and dryness of each branch. In addition, each The flow of the distribution branch cannot be quickly adjusted according to actual needs

Abstract

The invention discloses a gas-liquid two-phase self-adaption constant flow distributor. The gas-liquid two-phase self-adaption constant flow distributor comprises gas-liquid separation devices and gas-liquid mixers; a distribution branch at the rear of each gas-liquid mixer is provided with a self-adaption constant flow valve; a flow adjustment stop valve is arranged between each mixer and each self-adaption constant flow valve; a dryness flow meter is arranged at the rear of each self-adaption constant flow valve; due to the characteristic of constant flow of the self-adaption constant flow valves, the distributor can assimilate the influence of incoming flow or pressure fluctuation of certain working areas on the resistance characteristic of a system in a wide flow range, and performs self-adaption adjustment according to the designed flow; and the flow and dryness of other distribution branches are not influenced when the flow of certain distribution branches is changed, so the flow can be adjusted quickly.

Description

technical field [0001] The invention relates to a fluid distribution device, in particular to an adaptive constant flow distributor for gas-liquid two-phase fluid. Background technique [0002] In engineering fields such as petroleum, chemical industry and nuclear energy utilization, the distribution of gas-liquid two-phase fluids is often involved. In the distribution process, it is often necessary to maintain a consistent gas-liquid phase ratio in each distribution branch to avoid serious phase separation, and at the same time ensure that when the incoming flow or pressure in some working areas fluctuates (this fluctuation is often dynamic , randomly changing), can control the flow of each branch, keep the static set flow into each working area basically unchanged, and can realize rapid adjustment when it is necessary to adjust the flow of some branches, but not the flow of other branches affect dryness. This requires a device to control and adjust the distribution of in...
