Abstract
The invention provides a novel equal-dryness distribution device and method of gas-liquid two-phase fluid. The device comprises a gas-liquid separating pipe which is communicated with the downstream of a main path pipe, a liquid collecting box and a gas collecting box, wherein the liquid collecting box and the gas collecting box are communicated with the gas-liquid separating pipe; thin-wall tubes are mounted in the main path pipe and the gas-liquid separating pipe or in the gas-liquid separating pipe; rotational flow devices are also mounted in the main path pipe and the thin-wall pipes or the thin-wall pipes. According to the novel equal-dryness distribution device, the incoming two-phase fluid is divided into two parts through the rotational flow devices and the thin-wall pipes; one part is the single-phase fluid, namely, single-phase gas or single-phase liquid, and the other part is correspondingly the most of incoming liquid accompanied with small part of rest gas or the most of incoming liquid accompanied with small part of rest liquid, the former directly flows into the gas collecting box or the liquid collecting box, and the latter flows into the gas-liquid separating pipe; the gas phase and liquid phase are respectively collected into the gas collecting box and the liquid collecting box after separation and then are gathered and output after being distributed respectively, and thus the purpose of equal-dryness distribution is reached. With the adoption of the method, the size of the distribution device is reduced, and the adaptability scope of the flow rate and flow form of incoming two-phase fluid is expanded.
Description
Technical field
The present invention relates to a kind of fluid distributing apparatus and method, be specifically related to mass dryness fraction distributor and the methods such as a kind of novel gas-liquid two-phase fluid.
Background technology
Two-phase fluid distributes and is extensively present in the fields such as nuclear energy, oil, chemical industry and power.Main road two-phase incoming flow is assigned in each bypass line gas-liquid ratio in each branch road is consistent, and the mass dryness fraction such as is called and distributes.Two-phase fluid etc. mass dryness fraction distribute not only directly related with efficiency and economy under many circumstances, have close relationship with the safe and reliable operation of system especially.Therefore, each branch road that is assigned to of the mass dryness fraction such as two-phase fluid is an important technology.
At present, the main distribution method of using comprises both at home and abroad: symmetrical distribution method and phase-splitting combined method.
Symmetrical distribution ratio juris is to try hard to structurally accomplish full symmetric, distributes thereby the flow that makes two-phase fluid enter each branch road equates the mass dryness fractions such as realization.For example U.S. Pat 4505297, US5010910 are in such designing inwardly.But its shortcoming has, one, structure full symmetric, the each mass dryness fraction of its branch road can not guarantee consistent completely, because also will meet flow pattern when guaranteeing distribution structure symmetry and velocity flow profile symmetry just can make gas phase and liquid phase evenly enter each arm, but it is even that flow pattern and velocity flow profile are difficult to reach, for example, U.S. Pat 4505297 adds umbrella dividing plate in mixing header, U.S. Pat 5010910 arranges tapered blender carrying out inflow entrance, even if find to be difficult to guarantee like this, in practice the symmetric form of flow pattern and velocity flow profile; Its two, each branch road flow also needs symmetry, if having one or several conduit failure in branch road, be affected makes distribution effects variation to symmetry (structural symmetry and flow pattern velocity flow profile symmetry).
Phase-splitting combination ratio juris is that two-phase fluid is first separated, and distributes separately rear recombinant.For example U.S. Pat 5415195, US6250131, Chinese patent CN101402004A, CN102536182A.U.S. Pat 5415195 has been introduced a kind of Splitigator distributor, it is simple in structure, utilize the phase separation principle of threeway converging again output after gas-liquid separation, shortcoming is that its way outlet mass dryness fraction cannot regulate, be a fixed value, another shortcoming is that it cannot distribute incoming flow two-phase fluid completely, that is to say in order to reach its such distribution effects, main road incoming flow must have residual flow after distribution, and allocative efficiency is restricted.U.S. Pat 6250131 and Chinese patent CN101402004A utilize pipeline and gravity that incoming flow two-phase fluid is first divided into single-phase or approximate monophasic fluid, after distributing separately, converge again and the mass dryness fraction such as reach and distribute, but its shortcoming has: along with the increase of flow and the flow velocity of fluid in incoming flow, especially in the situation that main road pipe incoming flow flow pattern is annular flow, gas phase velocity is very large, its ability of carrying liquid is strengthened greatly, speed and the momentum of liquid phase are also very large simultaneously, make liquid phase become not malleable flow direction, when fluid process down-comer, liquid phase is difficult to enter completely down-comer, simple gravity and the down-comer of leaning on is difficult to make gas phase and liquid phase to separate completely, in gas phase pipeline, can carry a large amount of liquid phases, thereby the mass dryness fraction distribution effects such as affect, accommodation is narrower, in being used, actual field is very limited.Chinese patent CN102536182A passes through dilatation, two-phase incoming flow is all introduced in bulk container and utilized gravity to make gas phase and liquid phase natural separation, then gas phase and liquid phase distribute the mass dryness fractions such as rear recombinant reaches to distribute object separately, but its shortcoming is also obvious, whole incoming flows are separated in dilatation tank, and dilatation tank volume is inevitable very large, and equipment heaviness and material consumption are more, for the two-phase fluid of high temperature and high pressure steam and water, equipment volume has more just increased its dangerous hidden danger.
