High-speed gas reactor of the invention includes main flow caliber and the jet orifice (2) of its surface distributed, and main flow caliber is
A piece logical heart cylindrical tube, of cylindrical tube is mainstream gas entrance (1), and the other end of cylindrical tube is mixed gas outlet (3),
Multiple jet orifices (2) are distributed between (1) 1~1.5 times of mainstream gas entrance in cylindrical tube.Mainstream gas refer to gaseous mixture
The big gas of volume ratio in body, the Gas Jet that jet orifice (2) is passed through is the small gas of volume ratio in mixed gas.Intersect
In jet mixing, the diffusion of Convention diffusion, DIFFUSION IN TURBULENCE and molecule acts on the mixing of fluid simultaneously.Jet orifice is by TiCl4Fluid
Multiple jetses are divided into, main flow O is entered in Convention diffusion mode2In be mixed with.And then, due to the effect of DIFFUSION IN TURBULENCE, stream
Body forms the tiny gas group of smaller yardstick.Finally by the effect that molecule spreads, fluid is set to reach microcosmic well mixed effect.
The high speed reactor can be equipped with sealable shell and/or port structure, and shell can be the arbitrary shape for needing.
Multiple is evenly distributed with the cylindrical tube within one week along caliber everywhere apart from (1) one times of caliber of mainstream gas entrance to penetrate
Discharge orifice (2).The jet orifice of single circle distribution is by TiCl4Fluid is divided into multiple jetses, and main flow O is entered in Convention diffusion mode2
In be mixed with.And then, due to the effect of DIFFUSION IN TURBULENCE, fluid forms the tiny gas group of smaller yardstick.Expand finally by molecule
Scattered effect, makes fluid reach microcosmic well mixed effect.This jet orifice distributed architecture is simple, and mixing efficiency is high, can reach
To optimal mixed effect.
The diameter of the multiple jet orifice (2) is identical.
The number of the jet orifice (2) is 16~32, and the ratio of jet bore dia and cylinder caliber is 0.05~0.02：
0.12~0.05.
Proved by checking computations, in larger J/n when hole count is more2In the range of, the value of mixing unevenness M can be less than
0.05, and hole count it is less when, this scope also reduce (wherein J be momentum flux ratio, n be jet orifice hole count).This is due to protecting
When holding identical pitch of holes, hole count is more, and bore size is smaller.TiCl of the less jet orifice in aperture radial inflow4Gas
Thinner jet is divided into, itself and O2The micromixing yardstick that main flow is mixed to form accordingly reduces, and is more beneficial for mixing quick
Carry out.Therefore, in the reaction tube of a diameter of 0.2m, in order that mixing more Quick uniform, jet orifice hole count at least take 16 holes with

Degree (h/R).
The volume flow ratio of the Gas Jet and mainstream gas is 0.0313~0.106：1.With jet TiCl4And master
Stream O2Volume flow ratio increase, TiCl4The momentum of jet also increasingly comes greatly, and it penetrates into O2The depth of main flow also can
Increase.There is the moderate value of a comparing in jet penetration, jet penetration is not enough or excessive, under all causing jet orifice
Trip area's temperature distributing disproportionation is even, and TiCl4And O2Mixed effect it is undesirable.(it may be said that volume flow ratio is influence jet wearing
One factor of saturating depth, jet penetration determines mixed effect.Therefore, rational jet penetration scope is controlled.)
For the tubular reactor that this cross jet mixes, an important variation is TiCl4Jet and O2Main flow
Between dimensionless group, i.e. momentum flux is shown in formula (1) than J：
ρ and v represent TiCl respectively in formula4Jet and O2Density (the kgm of main flow-3) and speed (ms-1), subscript j
Represent TiCl4Jet, subscript m represents O2Main flow.At a given temperature and pressure, flow velocity vjAnd vmCan respectively by following formula
Son is calculated：
Vj=n (π d2/4)·vj (2)
Vm=(π D2/4)·vm (3)
Wherein VjIt is all jet orifice TiCl4Total volumetric flow rate (the m of jet3·s-1), d is jet orifice aperture (m), and n is hole
Number, VmIt is O2Main flow volume flow (m3·s-1), D is reaction tube diameter (m).
Formula (2) and (3) are substituted into formula (1) abbreviation can obtain：
At a given temperature and pressure, TiCl4Jet and O2Density ratio (the ρ of main flowj/ρm) it is 15.014.By formula (4)
Understand, variable parameter has TiCl4And O2Volume flow ratio (Vj/Vm), reaction tube diameter (D), jet orifice hole count (n) and aperture
(d)。
One important parameter is dimensionless jet pitch of holes, and it is in combination with all variable geometry ginsengs on reaction tube
Number, is defined as S, sees formula (5)：
