2) and tap water (H
2O) mixing zone 115, chlorine (Cl
2) 115 mix with tap water and to generate hydrochloric acid (HCl) and hypochlorous acid (HClO) in the mixing zone, obtain hypochloric acid water, from posticum 122 outflows.
In addition, what deserves to be mentioned is that when normal operation, electrolysis of hydrochloric acid liquid can not diluted by tap water, consult Fig. 5 and be another generating structure schematic diagram that is used to prepare the electrolytic system of hypochloric acid water of the present invention; Being provided with of said chlorine relief outlet 112 highly is higher than being provided with highly of said posticum 122; Illustrated in the diagram stop water service after; The water level of water jacket 12 can be reduced to below the level of chlorine relief outlet 112, so just avoids tap water to get into inside groove 11, dilute electrolyte.Thereby, adopt said structure to avoid electrolysis of hydrochloric acid liquid to be diluted by tap water.
Three, the structure of electrolyzer and placement form are used for stable supply electrolysis of hydrochloric acid liquid.
Consult Fig. 6, Fig. 6 shows the structural representation of inside groove of the electrolyzer of preferred embodiment.On the basis of said structure; The inside groove 11 of the utility model adopts the multi-channel inside groove, and the middle part of said inside groove 11 is provided with central electrolytic strip 23, and said central electrolytic strip 23 is divided into A district 13, B district 14 and C district 15 with inside groove 11; A district 13 is the electrolytic solution buffer zone; B district 14 and C district 15 are electrolysis zone, and electrolyte stream hand-hole 111 is located at A district 13, and yin, yang the two poles of the earth electrolytic strip 18,19 is located at C district and B district respectively.Being provided with of central authorities' electrolytic strip 23 can buffering salt acid electrolyte (HCl), optimizes electrolysis effectiveness.In the present embodiment, electrolyzer 1 20 °～40 ° placements of tilting, so that inside groove 11 also tilts 20 °～40 °, perhaps inside groove 11 20 °～40 ° settings of directly tilting.The below of said central electrolytic strip 23 offers the opening 231 of 2～4mm.In electrolytic process, the speed that pumps into of electrolytic solution can not be too fast, and electrolytic solution can be from the A district 13 gets into B districts 14; Be by convection into C district 15 by B district 14 then, blocked if electrolytic solution gets into the off-capacity or the duct in B district 14, at this moment; Electrolytic solution will be from the A district 13 gets into C districts 15, is by convection into B district 14 through opening 231 again, and the circulation of electrolytic solution is controlled more convenient; Avoid electrolytic solution in the inside groove more than the budget amount, make hypochloric acid water comparatively stable.
The electrolytic system that is used to prepare hypochloric acid water of the present invention has following characteristics: 1) adopt aseptate electrolytic system; With wide material sources, cheap tap water and hydrochloric acid is raw material; Owing to there is not a barrier film, easy and simple to handle, production efficiency is high, and in the production process; Do not produce alkaline water, can economize in raw materials in a large number; 2) electrolyzer of electrolytic system is divided into inside groove, water jacket, inside groove be located at water jacket inside and with the water jacket seal, inside groove holds electrolysis of hydrochloric acid liquid; Water jacket circulation tap water; Electrolysis of hydrochloric acid liquid generates chlorine after by electrolysis and discharges to combine with the tap water of water jacket from the chlorine relief outlet and generate hypochlorous acid (HClO), and the tap water that circulates of water jacket can also cool off the electrolytic strip of inside groove, can reduce the heat of electrolytic strip; Thereby lower the impedance of electrolytic strip, avoid influencing the growing amount of chlorine.3) in the electrolytic process, 20 °～40 ° placements of electrolyzer inclination avoid the circulation of electrolytic solution not smooth.4) the chlorine relief outlet is near the posticum setting, and being provided with of chlorine relief outlet highly is higher than being provided with highly of posticum, and chlorine mixes generation hypochlorous acid in the mixing zone with tap water, has avoided electrolysis of hydrochloric acid liquid to be diluted by tap water, and can stablize the output of chlorine.5) adopt intelligent controller,, control the chlorine production amount of electrolyzer, make the most effectively hypochloric acid water with electrolysis power, flow of electrolyte and water flow loop parameter as intelligent controller.7) through being set, relief valve, water pressure gauge, filter tap, two-way valve and restrictor can control the pressure and the discharge of current on the water service pipeline; Under meter is set to be used to measure discharge and to feed back to intelligent controller; Vacuum breaker is set is used to prevent that the hypochloric acid water that generates from refluxing.8) through on the hypochloric acid water escape route, mixing tank being set, can increase the combined amount of chlorine and water, the formation efficiency of hypochloric acid water is provided,, be used to measure the pH value of hypochloric acid water and feed back to intelligent controller through the soda acid inductor block is set.In sum, the electrolytic system that is used to prepare hypochloric acid water of the present invention simple in structure, and can effectively improve the production rate of hypochloric acid water, prepared hypochloric acid water has sterilization and disinfectant environmental protection effect.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
