Washing hydrogen water producing method and producing apparatus
View Patent ↗A method of producing washing hydrogen water in an embodiment, includes: a step of storing ammonia water in a first tank; a step of transferring the ammonia water from the first tank to a second tank; a step of diluting the transferred ammonia water with ultrapure water in the second tank; a step of mixing the diluted ammonia water into hydrogen water; and a washing step of washing an inside of the first tank by ultrapure water to remove fine particles derived from ammonia generated in the first tank.
1. A method of producing washing hydrogen water, the method comprising:
introducing ammonia water into a first tank to measure an amount of the ammonia water;
transferring the ammonia water from the first tank to a second tank;
diluting the transferred ammonia water with ultrapure water in the second tank;
mixing the diluted ammonia water into hydrogen water; and
washing an inside of the first tank with additional ultrapure water to remove fine particles derived from ammonia generated in the first tank.
2. The method of claim 1 , further comprising:
measuring the ammonia water in the first tank.
3. The method of claim 1 , wherein the first tank is filled with the additional ultrapure water during the washing causing the first tank to overflow.
4. The method of claim 1 , wherein the washing removes fine particles generated in the introducing and the transferring.
5. The method of claim 1 , wherein the ultrapure water and the additional ultrapure water have a resistivity of at least 18 MΩ·cm.
6. The method of claim 1 , wherein the hydrogen water has a dissolved hydrogen concentration at 25° C. under 1 atm of at least 0.1 ppm.
