Wherein, this electrochemical sterilized water treater have employed the opaque PVC bucket of sealing as water tank 1, and the clorox that can reduce generation decomposes by illumination; By the common salt aqueous solution (if configuration quality mark is the common salt aqueous solution of 4%-8%) in water tank 1; Circulated by high-pressure diaphragm pump 3 and extract reaction to electrolyzer 7, can greatly reduce the quantity of electrode, cost-saving, circulation is extracted and also can be made edible salt solution reaction more rapidly fully; This processor structure is simple, easy to operate, capping, and No leakage pollutes, and can in situ preparation clorox, guarantees sterilization and disinfection performance.
As shown in Figure 3, above-mentioned all electrolyzer 7 and water tank 1 and pump 3 parallel communication, especially, at all electrolyzers 7 and be provided with the water inlet pipe 41 and rising pipe 42 that common salt aqueous solution can circulate between water tank 1 and pump 3.Like this by electrolyzer 7 and arrange water inlet pipe 41 and rising pipe 42 between water tank 1 and pump 3, and be communicated with water tank 1 again by the parallel connection of all electrolyzers 7, can realize water tank 1, between pump 3 and electrolyzer 7 one-way circulation flowing, the edible salt solution in water tank 1 is made to accelerate flowing, the clorox that electrolysis is produced dissolves more fully in water tank 1, improves edible salt electrolysis of solutions efficiency.
In order to can be convenient, flexible switch according to carrying out synchronous or nonsynchronous electrode when different the electrode of two in electrolyzer 7, each electrolyzer 7 is controlled by a pole-reversing key 5, to meet actual needs.
Pole-reversing key 5 and the time relay 6 cooperating in the embodiment of the present invention, realizing the principle that electrolyzer 7 pole plate positive and negative electrode switches mutually is:
1) as shown in Figure 4, when the time relay 6 forward time arrives, start pole-reversing key 5 to work, namely to control contactor A1, A2 of pole-reversing key 5 closed for the time relay 6, keep B1, B2 to disconnect simultaneously, so two electrode case of electrolyzer 7 are, be positioned at above Fig. 3 electrolyzer 7 for cathode electrode, below be anode electrode;
2) as shown in Figure 5, when the time relay 6 reversed time arrives, start pole-reversing key 5 to switch, namely the time relay 6 controls contactor A1, A2 disconnection of pole-reversing key 5, keep B1, B2 closed simultaneously, so the situation of two electrodes of electrolyzer 7 is, be positioned at above Fig. 4 electrolyzer 7 for anode electrode, below be cathode electrode.
The pole-reversing key 5 that electrolyzer 7 connects, and controlled by the time relay 6, as aforesaid way achieve two electrodes in electrolyzer 7 occur after reacting certain hour positive and negative electrode switch time, electrode as anode before in the time of falling pole electrolyzer 7 becomes negative electrode, negative electrode becomes anode, instantaneous increase electric current can effectively be removed on negative electrode because salt impurities in water such as calcium ions and magnesium ions can react with hydroxide ion the oxyhydroxide dirt fouling generating and be insoluble in water, anode can reduce anode generation corrosion speed and degree after obtaining switching simultaneously, improve the work-ing life of interior two electrodes of electrolyzer 7.
The time relay 6 in this electrochemical sterilized water treater acts on and being also, when common salt aqueous solution pump 3 to electrolyzer 7 reacts by high-pressure diaphragm pump 3, react while be easily pumped to cyclic water tank 1 by electrolyzer 7 simultaneously, the reaction times of regulating electrolytic tank 7 is carried out by the time relay 6, specifically according to determine according to cyclic water tank 1 water yield and required clorox effective concentration, such as cyclic water tank 1 water yield 200L, massfraction is adopted to be the common salt aqueous solution of 4%-8%, actual required clorox effective concentration reaches 50mg/l, the cyclic electrolysis time if desired just can reach for 30 minutes, at this moment the working hour of the time relay 6 sets 30 minutes, this treater startup optimization auto stop after 30 minutes, actual required clorox effective concentration value can be reached.
Wherein two electrodes of above-mentioned each electrolyzer 7 are Ti electrode, and surface is also coated with iridium tantalum coating or tantalum platinum coating, because betatopic corrosion reaction can be there is in the electrode as anode in electrolyzer 7, anode electrode is caused to be oxidized, therefore two electrodes in electrolyzer 7 all adopt noble metal titanium, and surface is provided with iridium tantalum coating or the similar rare metal coating of tantalum platinum coating, can when electrolyzer 7 works, the consumption of noble metal titanium on electrode can be reduced, reduce electrode corrosion and the heavy metal ion that discharges, improve the work-ing life of electrode in electrolyzer 7, and electrolyzer 7 Inner electrolysis can be made to react more abundant.
In order to optimize the structure of electrochemical sterilized water treater, structure is compacter, mobile also convenient, is located in cabinet 2 by all integrated to electrolyzer 7, pump 3, pole-reversing key 5, the time relay 6 and power supply 10, as shown in Figure 2, cabinet 2 is connected with water tank 1 with rising pipe 42 by water inlet pipe 41.Concrete becomes upper strata 21, middle level 22 and lower floor 23 by cabinet 2 by detachable baffle for separating, it is at the middle and upper levels 21 for putting the time relay 6 and pole-reversing key 5, middle level 22 is for putting AC/DC transmodulator and rectifier 8, lower floor 23 is for putting all electrolyzers 7 and pump 3, in order to each equipment in cabinet 2 keeps dry, bottom the lower floor 23 in cabinet 2, be also provided with waterproof layer 24.
In order to improve controllability and the automatization performance of this electrochemical sterilized water treater; cabinet 2 arranges control panel 9; control panel 9 works for control pump 3 and the time relay 6, is provided with outlet 25 and the air switch 26 for the protection of overcurrent protection in circuitry each in cabinet 2 on cabinet 2 simultaneously.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
