LASER FRAGMENTATION OF MICRO- AND NANOPARTICLES IN FLOW CHANNELS AND DEVICE TO THIS END Russian patent published in 2015 - IPC B02C19/18 B22F9/04 

FIELD: process engineering.

SUBSTANCE: invention relates to fragmentation of micro- and nanoparticles of fluid flow. Claimed process comprises laser irradiation of disperse solution of microparticles and nanoparticles. Disperse solution is forced by recycling pump at the rate of 1-10 cm/s through 100-300 mcm diameter nozzle. Note here that said laser irradiation is conducted at the nozzle outlet. Claimed device comprises laser radiation source, standby tank for said disperse solution, 100-300 mcm diameter nozzle and recycling pump. The latter can divert said disperse solution of said standby tank and force it at the rate of 1-10 cm/s through the nozzle communicated with said recycling pump. Laser radiation source incorporates the optical system for feed of laser radiation and focusing lens. The latter focuses the laser radiation beam to disperse solution jet at the nozzle outlet.

EFFECT: higher efficiency.
