MIXING DEVICE FOR FURTHER PROCESSING OF WASTE GASES Russian patent published in 2017 - IPC F01N3/20 

FIELD: engines and pumps.

SUBSTANCE: mixing device (1) comprises a housing (4) having an inlet section (3) and located inside the housing (4), extending substantially parallel to the main injection direction (5) of the dosing device (6) and intended for supplying liquid and/or mixtures of liquid - gas in the inner tube (7), provided in the inner space (8) of the inner tube (7) with a premix (10) area. The body (4) has a spiral-shaped portion (13) of the body and a dosing device (6), arranged on the end face (11) of the body (4). The main waste gas flow (12) is directed between the body (4) and the outer side surface (14) of the inner tube (7) and is supplied to the main mixing area (16), and the partial waste gas stream (17) is fed to the pre-mixing area (10), located near the dosing device. A partial waste gas stream (17) through the pre-mixing area (10) enters the main mixing area (16) and the main waste gas stream (12) contains a large portion of the waste gas volume, than the partial waste gas stream (17).

EFFECT: increase the efficiency and reliability of waste gas cleaning with simultaneous disposal of its heat and captured components.
