Abstract:
In a mist nozzle, a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to the mist nozzle, so that a liquid flow is introduced from an upstream of a gas-liquid mixing section and a vicinity of a wall surface of the gas-liquid mixing section into the gas-liquid mixing section on an outer lid side. A pressurized gas is supplied from a gas supplier from a facing surface, so that a gas flow introduces into the gas-liquid mixing section and collides with the liquid flow, and a gas-liquid mixed flow is advanced to a spout portion while circulating the wall surface of the gas-liquid mixing section on the outer lid side. Therefore, it is possible to promote atomization of the liquid in the gas-liquid mixing section and spray a liquid having a smaller particle diameter.

Claim (Index 1):
A spraying apparatus comprising:\n a liquid storage tank that stores a liquid; a mist nozzle that spouts fine mist; a gas supplier that supplies a pressurized gas to the mist nozzle; and a liquid supplier that supplies a pressurized liquid to the mist nozzle, the pressurized liquid being obtained from the liquid stored in the liquid storage tank, wherein the mist nozzle includes a mist nozzle main body that has a liquid passageway through which the pressurized liquid is supplied from the liquid supplier and a gas passageway through which a pressurized gas is supplied from the gas supplier, an inner lid that is disposed at a tip of the mist nozzle main body, covers an opening of the liquid passageway, and has a flat inner end portion, an outer lid that is disposed at the tip of the mist nozzle main body, covers the inner lid, covers an opening of the gas passageway, and has a flat outer end portion facing the inner end portion of the inner lid, a gas-liquid mixing section that is disposed between the inner lid and the outer lid, is formed at a space of a disc-shaped profile between the inner end portion of the inner lid and the outer end portion of the outer lid, and mixes a gas flow flowing through the gas passageway and a liquid flow flowing through the liquid passageway, a liquid inlet that is provided so as to penetrate at least one portion of the inner end portion of the inner lid in a circumferential direction, communicates with the gas-liquid mixing section, and allows a liquid flow flowing through the liquid passageway to enter the gas-liquid mixing section, a gas inlet that is disposed on a side portion of the gas-liquid mixing section between the inner lid and the outer lid so as to communicate with the gas-liquid mixing section, and allows the gas flow flowing through the gas passageway to enter the gas-liquid mixing section toward the liquid flow entering the gas-liquid mixing section from the liquid inlet, and a spout that is provided so as to penetrate the outer end portion of the outer lid, communicates with the gas-liquid mixing section, and spouts as the fine mist a liquid atomized by mixing the gas flow and the liquid flow in the gas-liquid mixing section.
