Abstract

PURPOSE:To atomize a high-density liq. by separating a closed vessel into first and second chambers, using a ceramic filter as the partition, providing a fluid supply port to the first chamber and furnishing a fluid discharge port to the second chamber. CONSTITUTION:A liq. and a gas are alternately supplied to the only one supply port 5. The liq. supplied from the supply port wets the three porous layers 8, 9 and 10 of the ceramic filter 2. The gas supplied to the first chamber 4 from the supply port blows the liq. contained in the three porous layers of the ceramic filter into the second chamber, hence the liq. is atomized, and the gas and the atomized liq. are discharged from the discharge port 6 through the second chamber. The atomized liq. having specified and uniform particle diameter can be easily obtained.
