ATOMIZING METHOD FOR LIQUID TO UNIFORM SIZE AND DEVICE FOR EMBODIMENT THEREOF

摘要

PURPOSE:To generate a large amt. of micro liquid droplet groups having uniform sizes by punching microhole groups of uniform sizes in a structural body by laser working techniques or the like, supplying the pressurized liquid into said punched hole groups and applying high frequency oscillations of ultrasonic waves to the liquid column groups generated by the punched hole groups. CONSTITUTION:A large number of uniform microholes are punched to a thin sheet 1 of stainless steel or the like by a laser beam working or electron beam working method, and the sheet 1 is mounted airtightly by means of an O-ring 3 or welding into an outflow port 2 for liquid. When pressurized liquid is fed into the port through a liquid feed port (a), the liquid flows out through the microholes of the sheet 1 in the form of a large number of micro-sized liquid columns. High frequency oscillations are applied to a device 4 in the direction (b) parallel or the direction (c) vertical to these liquid column groups, whereby a large amt. of the micro liquid droplet groups 12 of uniform sizes are generated.
