Immersion equipment for mixing two liquids

The invented submersible device for mixing two fluids, from which at least one is a liquid is formed by a tube (1) for reception of fluids and open at its both axial ends, further by at least two nozzles (2, 3) intended for supply of fluids and by at least one through-flow channel (4, 5) defined by walls in which the nozzles (2, 3) protrude by their one end and which has its other end leads in the tube (1). At the height, where the through-flow channel (4, 5) is led in the tube (1) defines a percussion zone (PZ) for percussion of fluid flows injected by the nozzles (2, 3) and leaving the through-flow channel (4, 5) in each other. At least one wall of the through-flow channel (4, 5) is formed by a portion of the tube (1) wall.
