PROCESS FOR PRODUCING WATER ADDED WITH HYDROGEN AND APPARATUS THEREFOR

摘要

A process for producing a water added with hydrogen containing a large quantity of microbubbles with the intent of expanding the industrial applicability of water added with hydrogen through incorporation of a large quantity of microbubbles; and an apparatus therefor. Accordingly, there is provided diffusion compartment (5) of double tube structure wherein multiple tube bodies provided with porous element (6) of given pore diameter are disposed in roughly linear form along the longitudinal direction thereof. Raw water and hydrogen are supplied to one of the tube bodies, and the supplied raw water and hydrogen are mixed together in the diffusion compartment (5) to thereby obtain a mixed fluid of raw water and hydrogen. The mixed fluid is caused to pass through the porous element (6) so as to effect diffusion, and the mixed fluid of raw water and hydrogen having passed through the porous element (6) is fed at high pressure to an adjacent tube body to thereby effect mixing with hydrogen in the diffusion compartment (5) of the adjacent tube body. Thereafter, the mixture is caused to pass through the porous element (6) so as to effect diffusion. Thus, there can be accomplished continuous production of a water added with hydrogen containing a large quantity of hydrogen gas microbubbles.
