The vibration dispersion granulation was a program that has been studying in recent years, but was stuck in gas-liquid vibration dispersion. While the situations of the two-phase liquid-liquid vibration dispersion were studied in the paper. And the technology of the uniform droplet was obtained by imposing periodic amplitudes and frequencies on the liquid-liquid vibration dispersion device which was designed in the experiment. In order to study conveniently, the iodine kerosene was acted as jet breakup liquid and the water as the stationary-phase liquid meanwhile. In the paper, the relationship between the parameters of frequency, amplitude, flow velocity, diameter ratio as well as aperture and the number, dimension and the uniformity of the jet droplets was explored thoroughly.1. The influences of frequency, amplitude, aperture and diameter ratio on the unformity and particle size of the droplets were studied in liquid-liquid vibration dispersion granulation. It was drawn from the results that each parameter had an optimal value range, neither was it too large nor too small, otherwise the uniformity would worsen. What's more, the droplet size would get small if any one of the parameters changed big.2. The optimal frequency theoretical mode (fopt=uikopt/Ï€di) was established in the liquid-liquid vibration dispersion system, and the jet velocity of the jet liquid of the nozzle was deduced(ui=u0d02/di2).3. The relationship between amplitude and frequency was established by nonlinear fitting the optimal amplitude4. The fracture behavior of the liquid-liquid vibration, namely the frequency imposed was exactly equal to the number of the unform droplets was researched. And also the relationship between various parameters and the size of the droplets was obtained...
