LIQUID ATOMIZATION DEVICE

摘要

A liquid atomization device includes: a first gas spray unit and a second gas spray unit; a liquid outflow unit for flowing out a liquid; a gas-liquid mixing area where a gas flow sprayed from the first gas spray unit, a gas flow sprayed from the second gas spray unit, and a liquid which flows out from the liquid outflow unit are made to collide against each other to thereby atomize the liquid; a projection formed to project out of the device such that its cross section projects in a convex manner, the gas-liquid mixing area being formed in the projection; a spray slit formed in the projection along a wide angle spray direction of mist produced by the gas-liquid mixing area; and a restriction portion formed near a bottom of the spray slit such that the restriction portion is inclined in the wide angle spray direction of the mist.
