The high speed rotation in atomization cavity is accelerated to mix into before atomization gas import, pressure fluid channel crosses with atomization gas channel
Spraying by spray-hole afterwards, import is vertical with spray-hole；
3, compared with traditional double fluid atomization nozzle, the atomizer structure is simple, low manufacture cost；Atomization cavity is selected resistance to
Grind the casting of steel 30CrMo precision, cast molding of pressure fluid import and atomization gas import, without machining；It sprays piece and selects tungsten
Steel, erosion resistant, due to wolfram steel higher cost, base cover sprays piece and uses embedding technique；Core arrangement designs reverse taper form, makes gas
Liquid mixture is in atomization cavity high speed rotation and presses to spray-hole, and inner core and spray-hole are apart from adjustable.
Therefore, the operating method for being suitable for the atomizer by sludge Direct spraying to desiccation tower of the invention, compact-sized, spray
Fog effect is outstanding.
