FIELD: engines and pumps.
SUBSTANCE: device 1 comprises mixing channel 2, first flow guides 3 to swirl (V1) offgas in mixing channel 2. Device 1 comprises injectors 5 of fine aerosol into offgas in mixing channel 2, to the centre of first swirl (V1). Injection chamber 6 is arranged upstream of mixing channel 2. Chamber 6 receives offgas and is connected to mixing channel 2. Offgas received in chamber 6 flows to mixing channel 2 at the centre of first swirl V1. Injectors 5 force fluid into injection chamber 6. Device 1 comprises second flow guides 4 to create offgas second swirl V2 in channel 2, concentrically and outward relative to first swirl V1, so that offgas in second swirl spin in direction opposite aforesaid first direction.
EFFECT: accelerated evaporation owing to efficient spraying.
