Background technology
Percussion flow is to realize a kind of important method quickly mixed, is widely used in chemical field, and percussion flow is than tradition
Method is more efficient, energy consumption is lower.Impact flow reactor is exactly the device for being used to implement percussion flow process.Collision jet makes two
Fluid streams at a high speed hit by opposite flowing, reaches high relative velocity in shock moment, axial velocity goes to zero, and is converted into diameter
To flowing, in high turbulence impingement region, the external drag in transmittance process can be effectively reduced, strengthens Mass and heat transfer, promoted mixed
It closes.
In recent years, impact flow reactor has application chemically reacting, crystallize and prepare superfine powder etc., but relates to
And to reactor be mainly used for preparing small particle chemical substance, the size of reactor is smaller, it is difficult to carry out large-scale production.
A kind of impact flow reactor is provided in patent application CN103011119A and is used to prepare nano ferric phosphate, which includes two
The identical caliber channel of root, two strands of solution flowed in opposite directions are completed to hit in intersection with 15~180 ° of angle, this reaction
Device is suitble to prepare nano-particle, but due to there is no reaction cavity, so being not suitable for the mixing of two kinds of solution.Patent application
The design of another impact flow reactor is provided in CN103611487A, which includes mixing chamber, and designs one
Control unit and the flow of two ratio valve regulation chargings, are fluctuated by adjusting flow according to preset waveform, so as to make shock
The striking face rectilinear oscillation of stream.But if it happens shortcoming, which is reactor, to be blocked, then will cause to flow back, in addition the reaction
The smaller unsuitable scale application of device size.
