The effect of invention
Electrolytic ionic water generation method of the present invention has effect as described below.
(1) Jiang Yuanshui is stored in and generates in storage tank, and aqueous electrolyte liquid is stored in the electrolytic solution storage tank generating in storage tank, carrying out electricity decomposes, thereby can be only with necessary amount batch type in generating storage tank, generate electrolytic ionic water, in the situation that the concentration of the former water yield in generation storage tank and the aqueous electrolyte liquid in electrolytic solution storage tank is certain, the time that only regulates electricity to decompose just can generate the electrolyzed alkaline water of desired pH.
(2) owing to carrying out electricity under the state at the former power and water solution matter aqueous solution of storage, decompose, so can make the gap between ion-exchange membrane and electrode, situation than the continous way generation method of the former power and water solution matter aqueous solution of continuous supply is wider, the former power and water solution matter aqueous solution can both easily pass through gap, even contain the tap water of calcium or magnesium etc. in former water, be also difficult to adhere to calcium or magnesium on electrode or ion-exchange membrane.Thus, along with the process of electricity resolving time, electric decomposition efficiency can not reduce.In addition, by described gap is broadened, oxygen becomes bubble in anode side and occurs, and hydrogen becomes bubble at cathode side and occurs, because they are from interstitial diffusion, so can be by gas bubble blockage.Thus, the productivity of electrolytic ionic water is compared and is improved with continous way.
(3) owing to being difficult to adhere to calcium or magnesium etc., thus can make regularly cleaning during elongated, safeguard easily, can not interrupt because regularly cleaning makes to generate continually, so the productivity of electrolytic ionic water can not reduce yet.
Electrolytic ion water generating device of the present invention has following effect.
(1) due to have can store former water generation storage tank, can store the electrolytic solution storage tank of aqueous electrolyte liquid and can separate the ion-exchange membrane that generates the former water in storage tank and be immersed in the aqueous electrolyte liquid of the electrolytic solution storage tank in former water, so can be only with necessary amount batch type generate the electrolyzed alkaline water of desired pH.
(2) because Jiang Yuanshui is stored in generation storage tank, aqueous electrolyte liquid is stored in to electrolytic solution storage tank, can generate electrolytic ionic water, so can make the gap of gap, ion-exchange membrane and the positive plate of ion-exchange membrane and negative plate broaden, former water, aqueous electrolyte liquid can easily pass through these gaps, the liquid throughput of time per unit increases, many with the former water of two electrode contacts or total quantitative change of aqueous electrolyte liquid, thereby can compare the electrolyzed alkaline water that generates desired pH with the short period of time with continuous generating mode, the productivity of generation is high.
(3) owing to can making described gap broaden, even so contain calcium or magnesium etc. in former water, calcium or magnesium are also difficult to be attached on electrode or cationic exchange membrane, gap can not be stopped up, can maintain for a long time electric decomposition efficiency, contribute to the raising of the formation efficiency of electrolyzed alkaline water.In addition, even if be attached with calcium or magnesium etc., cleaning or maintenance easily, can easily be removed dirt settling by cleanings such as sour waters.Can make regularly cleaning during elongated, safeguard easily.In situation about making regular check on continually, for inspection makes the generation of electrolyzed alkaline water, stop, because its frequency tails off, productivity can not reduce yet temporarily.And even at the bubble of anode side generation oxygen, at the bubble of cathode side generation hydrogen, these bubbles are also difficult to stop up described gap, thereby are difficult to be blocked by the aqueous electrolyte liquid in described gap, the productivity of electrolytic ionic water is difficult to reduce.
(4) owing to generating electrolytic ionic water with batch type, so if make magnitude of voltage and current value certain, make the concentration of aqueous electrolyte liquid certain, only, by regulating conduction time, just can generate the electrolyzed alkaline water of desired pH value.
(5) because the generation storage tank of described electrolytic ion water generating device and the both sides of electrolytic solution storage tank or a side are insulating material system, so can make reliably to generate storage tank and be immersed in the electrolytic solution storage tank insulation in its former water.
(6) positive plate and the negative plate of the ion-exchange membrane of electrolytic ion water generating device, clamping ion-exchange membrane are arranged on to electrolytic solution storage tank, positive plate is configured in to the inner face side of electrolytic solution storage tank, negative plate is configured in to the exterior side of electrolytic solution storage tank, can changes ion-exchange membrane according to electrolytic solution storage tank.
(7) adopt ion-exchange membrane, positive plate and negative plate assembling all-in-one-piece box part, and can dismounting with respect to electrolytic solution storage tank, easy thereby the replacing of ion-exchange membrane becomes.
