METHOD OF DESALINATION OF WATER AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC C02F1/12 

FIELD: water and air purification technology.

SUBSTANCE: invention relates to a method and a device for desalinating water. Method of desalination of salty water, in which desalinated salt water, supplied in form of jet or shroud, is periodically exposed to impact of strong shock wave and high-speed flow of hot gaseous detonation products, leading to fine aerodynamic fragmentation of jet or shroud of desalinated salt water. Formed two-phase torch is supplied tangentially to vortex zone, where in conditions of strongly swirled high-temperature flow there is fast evaporation of microdroplets of desalinated salt water with formation of finely dispersed crystalline sea salt, separated from gaseous detonation products and steam due to the field of centrifugal forces. Gaseous detonation products and water vapor are discharged from the vortex zone into the condensation zone of water vapor and its separation from gaseous detonation products. Salt residue is continuously removed from the vortex zone in the form of finely dispersed crystalline sea salt. Method is realized in a device in which systems for fragmentation and evaporation of desalinated salt water are made in form of pulse generator of strong shock wave and high-speed flow of hot gaseous detonation products, connected to vortex reactor for evaporation of microdroplets of desalinated salt water with formation of finely dispersed crystalline sea salt, connected to condenser water vapor. Water vapor condenser is equipped with system for removal of gaseous detonation products and system for discharge of desalinated water to consumer.

EFFECT: invention provides desalination of salty water by means of thermomechanical action on jet or shroud of salt water with strong shock wave and high-speed flow of hot gaseous detonation products obtained in cyclic working process with pulse-detonation burning of one or another fuel.
