FIELD: process engineering.SUBSTANCE: invention relates to dispersion of suspensions. Device for dispersion of suspension (2) by at least one gas (7, 7a, 7b), particularly for flotation machine (100) comprises dispersing nozzle (10, 10'). The latter comprises the following components arranged one after another along suspension flow: suspension nozzle (3', 3", 3'") converging along the flow, mixing chamber (4) including said nozzle (3', 3", 3'"), mixing tube (5, 5') adjoining said mixing chamber (4) and converging along the flow, and at least one gas feed line (6, 6a, 6b) to feed at least one gas (7, 7a, 7b) into mixing chamber (4). Suspension nozzle (3", 3"') has at least N gas channels (31), larger than 3, connected with said gas feed line (6, 6a, 6b) to terminate at end side(3a", 3a'") of suspension nozzle (3", 3"') facing said mixing chamber (4). Device comprises A gas valves (V). Note here that N=A and everyone of N gas channels incorporates one gas control valve (V) to metre out gas (7a) fed to suspension (2) via appropriate gas channel (31).EFFECT: better dispersion of suspension and gas.19 cl, 20 dwg |
