The existing ice particle jet surface treatment technology is prone to ice particle adhesion during application, which seriously affects the surface treatment efficiency. Based on the basic structure of the jet pump, the ice particle air jet surface treatment technology is proposed for the instant preparation and utilization of ice particles, which solves the problem of ice particle adhesion and clogging. In order to realize the efficient utilization of ice particles and the high-speed jetting of ice air jet, the integrated jet structure of ice particle ejection and acceleration was developed. The influence of the working nozzle position (Ld), expansion ratio (n) and acceleration nozzle diameter ratio (Dn), length-to-diameter ratio (Ln) on the ice particle ejection and acceleration was systematically studied, and the structural parameters of the injector were determined with the impact kinetic energy of ice particles as the comprehensive evaluation index, and the surface treatment test was carried out to verify the results. The results of the study show that: under 2 MPa air pressure, the ejector nozzle parameters of n = 1.5, Dn=4.0, Ld=4, Ln=0 mm, can be sufficiently ejected to accelerate the ice particles. The structure parameters of the aluminum alloy plate depainting test, can obtain a larger radius of paint removal and make the aluminum alloy plate surface smoother, aluminum alloy surface roughness from 3.194 ± 0.489 m to 1.156 ± 0.136 m. The immediate preparation and utilization of ice particles, solved the problem of ice particles in the engineering application of air jet technology, ice particles bonding and storage problems. The instantaneous preparation and utilization of ice particles solves the problems of ice particle adhesion and storage in the engineering application of ice particle air jet technology, and can provide a feasible technical method in the field of material surface treatment.
