FIELD: galvanic and chemical industry. SUBSTANCE: nozzle orifice is made in form of module panel which has parallel rows of nozzle holes. Axes of the holes from any subsequent row are shifted relatively axes of the holes of previous one. Number of rows is chosen according to relation N =(D/d), where D is diameter of entrance nozzle hole, d is diameter of exit nozzle hole. In this case value of shift of axes of any subsequent row relatively holes of previous row is equal to diameter of exit part of nozzle hole, and N is equal to 3. EFFECT: improved efficiency. 2 cl, 2 dwg
