Two stage shear coaxial injector to increase in transfer efficiency and atomization performance

摘要

The present invention relates to a two-stage shear coaxial injector apparatus, and more particularly, the atomization performance is improved by the jets injected from the second stage, and at the same time, the jets formed form an air curtain to prevent the liquid jet from scattering. A two stage shear coaxial injector with improved efficiency. The present invention is a nozzle body; A liquid nozzle installed on the nozzle body; A first stage gas nozzle positioned on the coaxial of the liquid nozzle to atomize the liquid injected from the liquid nozzle; And a second stage gas nozzle positioned on the coaxial of the liquid nozzle and refining the atomized liquid in the first stage gas nozzle.
