Kind Code:
A1
Abstract:
This spraying nozzle is provided with: a first cylinder part in which there are formed a cleansing liquid introduction opening for introducing a cleansing liquid, a gas introduction opening for introducing a gas along a direction orthogonal to the flow direction of the cleansing liquid, and a discharge opening for discharging a mixed fluid of the cleansing liquid and the gas; a throttling part provided farther upstream in the flow direction of the cleansing liquid than a merge part at which the cleansing liquid and the gas merge; and a second cylinder part in which there is formed a second gas introduction opening for introducing the gas into a second flow path that communicates with the gas introduction opening. This gas-liquid mixing device includes: the spraying nozzle; and an expansion joint that includes a barrel part configured so as to be capable of expanding and contracting, the expansion joint being provided to a cleansing liquid introduction line for sending the cleansing liquid from the cleansing liquid introduction opening into a first flow path and/or to a gas introduction line for sending the gas from the second gas introduction opening into the second flow path.
