Fluid handling device

Abstract

[Problem] To provide a fluid conveying device that can suppress pressure loss. [Solution] The nozzle portion 2 of the fluid conveying device 100 includes a first nozzle outlet 32, a second nozzle outlet 42, a third nozzle outlet 52, and a plurality of fourth nozzle outlets 45. The first nozzle outlet 32 ​​is formed by a first partition 3 and ejects a first jet. The second nozzle outlet 42 is formed in an annular shape on the outer periphery of the first partition 3 and ejects a second jet. The third nozzle outlet 52 is formed in an annular shape surrounding at least a portion of the outer periphery of the second partition 4 and ejects a third jet. A support member 46 supports the third partition 5 on the outer periphery of the second partition 4. A plurality of support members 46 are provided at predetermined intervals in the circumferential direction. The plurality of fourth nozzle outlets 45 are provided on the second partition 4 and eject a portion of the second jet J2 as a fourth jet J4. The support member 46, the fourth nozzle 45 and the second nozzle 42 are arranged sequentially from the third nozzle 52 side along the transport direction of the third jet.
