<P>PROBLEM TO BE SOLVED: To provide a gas-liquid mixing nozzle device having a slot element reducing a flow rate in which a liquid enters a gas-liquid mixing concave portion. <P>SOLUTION: The gas-liquid mixing nozzle device includes a base 102 having a first to a third side surfaces, a sealing element 104, a throttle element, and a nozzle 108. The base includes a gas passage 200 and a liquid passage 300 provided in a concave state on the first side surface, and a liquid housing concave portion 400 and a gas-liquid mixing concave portion 500 respectively provided in a concave state on the second side surface and the third side surface. The liquid passage passes through from the first side surface to the liquid housing concave portion, the gas passage and the liquid housing concave portion pass through respectively from the first side surface and the second side surface to the gas-liquid mixing concave portion, and the liquid housing concave portion communicates to the gas-liquid mixing concave portion at a first part. The sealing element is provided at an opening of the liquid housing concave portion, and the throttle element projects from the sealing element to the first part, and reduces the cross-sectional area. Further, the nozzle is joined to an opening of the gas-liquid mixing concave portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
