PROBLEM TO BE SOLVED: To easily disperse even particulates not more than 1μm in gas phase. SOLUTION: A solvent containing particulates in a coagulated condition is put in a vessel 1. Pressurized air is forcedly fed in an atomizing means 7 from a duct 5. Then, the solvent sucked through a capillary 3, and becomes a mist shape in a cavity 6. Microscopic droplets becoming a mist shape contain coagulated particulates as a nucleus. When a metallic pipe 8 to introduce the mist-shaped droplets is heated to a temperature sufficiently higher than a boiling point of the solvent, the mist-shaped droplets are rapidly heated. Then, the droplets are suddenly evaporated and boiled at heating time, and the coagulated particulates can be dispersed in a gas phase. |
