当量にのぼり、吸蔵に至る。It is confirmed that the raw water is filled in the water passage chamber 3 through the water supply passage 20a, penetrates and passes through the filter cloth 4, and enters the inside of the activated carbon block filter in the porous water purification member 5.
A DC voltage (1.4 V) was applied to the cylindrical body 2 and the rod-shaped conductor 7 via the positive terminal 24 of the positive electrode and the leaf spring 23 of the negative electrode. The outer peripheral surface of the porous water purification member 5 is a positive electrode, which is the opposite electrode of the inner wall surface of the cylindrical body 2 of the negative electrode, and the peripheral wall of the central through-hole 6, which faces the rod-shaped conductor 7 of the positive electrode, is the negative electrode. While the raw water is purified in the permeation layer in the activated carbon block filter, the hydrogen gas mainly generated by the electrolysis dissolves, and a part of the gas becomes bubbles, so that the internal pressure of the water passage chamber 3 increases. The umbrella nut 9 is pushed out into the through hole 6 and is located at the top of the water purifier 1.
Through the drainage section 8 through the opening 9c. The water permeation pores in the activated carbon block filter have an average of 0.15 μm and a porosity of 40%, have a very large pressure loss, and require a large pressure to push out water in the permeation layer of the activated carbon block filter. . Therefore, the retained gas that is not involved in the electrolysis in the water passage chamber 3 mainly dissolves hydrogen gas more largely than dissolution under atmospheric pressure, and further diffuses and adsorbs hydrogen gas into activated carbon pores. Rise to a considerable amount, leading to occlusion.

スを脱着することになる。The amount of hydrogen gas absorbed by the activated carbon block filter in a dry state was examined using ASAP (manufactured by Shimadzu Corporation), and the result was as shown in FIG. Next, a digital micro pressure gauge was set up in the water passage chamber 3 and the pressure change in the water passage chamber 3 was examined without drainage, and the results are as shown in Table 1. From Table 1, 0.351 kgf / cm for 150 minutes
Since the peak was at 2 and then decreased, it is considered that the water was pushed out by the pressure of the hydrogen gas, the water was displaced, and the permeation hole was completely passed by the hydrogen gas. This means that the atmospheric pressure was maintained for about three hours when the pressure began to decrease, and that the hydrogen gas was absorbed by 530 cc / g, which was a 32% increase from the initial level, in the graph of FIG. In order to desorb the gas once adsorbed, it is necessary to apply energy from the outside such as decompression and heating. However, when water continuously passes through the permeable layer, the pressure of the outer peripheral surface 4 m of the porous water purification member is reduced. No matter how high the pressure is, it is appropriate to judge that the hydraulic pressure in the permeable layer decreases, so that the occluded gas is desorbed by the reduced pressure.

水素ガスを脱着溶解していると考えることができる。Table 2 shows that the amount of dissolved hydrogen gas in the waste water is extremely small, but is reliably generated in the applied voltage range of 6 V to 1.5 V, and almost no oxygen gas is generated. . In natural water, oxygen is 10 mg / L.
The dissolved oxygen amount was reduced, but the amount of dissolved oxygen was reduced in the range of 1 to 6 V due to discharge to the outside of the system by bubbling with hydrogen gas or reduction or the like. In such a situation where the reduction potential is negative, even if it is continuously drained, it exceeds 30 L before it reaches ± 0. Therefore, it can be considered that the absorbed hydrogen gas is desorbed and dissolved in the permeated water every time.

る。According to the active hydrogen storage water purifier of the present invention,
By directly applying a DC voltage to the raw water in the water passage compartment defined by the inner wall surface of the cylindrical body, the electrolysis of the raw water proceeds efficiently. In addition, the water impregnated in the activated carbon block filter becomes a permeation resistance, and the pressure of the water passage chamber rises due to the hydrogen gas generated during closing, which is advantageous for the adsorption of the hydrogen gas to the activated carbon block filter, and conversely, the water At the time of permeation, the hydraulic pressure is reduced, and the occluded hydrogen gas is desorbed by the reduced pressure. At that time, when the ultrafine hydrogen particles adsorbed in the fine pores of the activated carbon are desorbed and dissolved in purified water, it is assumed that they maintain the same size as at the time of adsorption, so they have extremely high reduction activity, For active oxygen, etc.
It can be the most effective antioxidant. Such an effective antioxidant effect can be applied not only to drinking but also to hot water for bathing.
