Abstract: A liquid atomization device includes a nozzle body. The nozzle body includes: a first gas spray portion and a second gas spray portion for spraying two gas flows; a liquid passage having a passage through which liquid flows by formation of the two gas flows sprayed by the first gas spray portion and the second gas spray portion; a gas-liquid mixture area where the gas flow sprayed from the first gas spray portion and the gas flow sprayed from the second gas spray portion are made to collide against liquid which flows from the liquid passage to atomize the liquid; and a spray outlet for spraying mist atomized in the gas-liquid mixture area to outside.

Abstract: A liquid atomizing device includes a first gas injection portion and a second gas injection portion for making two gas flows collide against each other; a liquid outflow portion from which liquid flows out; a gas-liquid mixing area portion where a gas flow injected from the first gas injection portion, a gas flow injected from the second gas injection portion and liquid which flows out from the liquid outflow portion are made to collide against each other to atomize the liquid; an injection outlet portion in which the gas-liquid mixing area portion is formed; and a slit portion formed in a tip end surface of the injection outlet portion along a direction in which the mist is injected widely.

Abstract: A liquid atomizing method in which a collision portion formed by making at least two gases collide with each other, or a portion including the collision portion, and liquid are made to collide with each other to atomize the liquid. A liquid atomizing device includes at least two gas injection portions from which gases are injected, and a liquid injection portion from which liquid is injected, a collision portion formed by making gases injected from the at least two gas injection portions collide with each other or a portion including the collision portion, and liquid injected from the liquid injection portion are made to collide with each other to atomize the liquid.
