Fluid mixing output apparatus and fluid utilization apparatus using the same

Abstract

By homogeneously mixing a plurality of fluids, when mixing a gas with a liquid, it is possible to mix a large amount of gas into the liquid, so that large bubbles are not generated, and fine bubbles (in some cases, fine bubbles including microbubbles or ultra-fine bubbles) can be mixed into the liquid. A fluid mixing output apparatus of the present disclosure includes a housing and an internal structure accommodated in the housing. The housing is provided with a plurality of fluid supply ports for supplying at least a first fluid and a second fluid and a fluid outlet at its downstream end for outputting a plurality of fluids after mixing the plurality of fluids. The internal structure includes a first portion, a second portion, a third portion, and a fourth portion. The first portion includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The second portion is located downstream from the first portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. The third portion is located downstream from the second portion, and includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The fourth portion is located downstream from the third portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. One of the plurality of fluid supply ports of the housing is formed in a portion corresponding to the vane of the third portion, and the second fluid is supplied to the third portion and supplied to the fourth portion as a swirling flow while being mixed with the first fluid.
