METHOD FOR SEPARATION OF PARTICLES SUSPENDED IN GAS FROM GAS FLOW AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC B04C5/18 

FIELD: technological processes.

SUBSTANCE: invention relates to procedure of separation of particles suspended in gas from gas flow. Method consists in the fact that gas flow with particles suspended in it is sent into peripheral part of cylindrically shaped volume along tangent to circumference of inner cylindrical surface, this, vortex motion of gas flow is created, and particles suspended in flow are moved to periphery of flow under action of centrifugal force, and particles are braked against inner surface of volume, and after braking particles are collected in another closed volume-collector of particles. In collector underpressure is pulled, at the same time pressure in closed volume of particles collector is maintained as lower than pressure in volume of cylindrical form, afterwards particles separated from gas flow are collected into receiving hopper. Device comprises body, fan with motor, collector of particles, ejector for creation of underpressure additionally to the one pulled by fan, and receiving hopper with detachable cover, on which it is mounted. Narrow part of particle collector lower part adjoins receiving cavity of ejector, and outlet nozzle of ejector is connected to receiving hopper. Device is equipped with sieve installed above receiving cavity of ejector. Receiving hopper is equipped with vortex extinguisher.

EFFECT: improved efficiency, quality of gas flow, with application of invention in the field of polymer powder coats application onto metal and non-metal parts, provision of possibility for secondary use of separated particles in new process cycle directly after completion of previous cycle of powder coating application.
