Electrolytic disinfectant water generation system with electrode scale prevention function {Water treatment system for Prevention of cation on the disinfectant Generator}

The present invention relates to an electrolytic disinfection water generating device that generates electrolyzed disinfectant water after receiving water, and more particularly, an electrode scale prevention function capable of preventing the scale of electrodes generated when generating disinfection water by electrolyzing an electrolyte It relates to an electrolytic disinfection water generating system having a.

In general, in modern times, the population is densely populated, group feeding and burial are frequent, and the movement of the population is large due to the development of transportation. As a result, bacterial infectious diseases occur frequently and are becoming more widespread, and the importance of hygiene cannot be overemphasized under these circumstances.

According to such living conditions, various types of electrolytic disinfection water generating devices including the prior art applied by the applicant of the present application are being developed and used.

That is, the electrolytic disinfection water generator is an electrolyte, for example, salt, hydrochloric acid. Calcium carbonate, sodium carbonate, sodium hydrogen carbonate, etc. are electrolyzed according to the purpose and use to produce electrolytic disinfection water necessary for daily life.

However, the electrolysis method as described above is inevitably a uniform result by forming a scale S1 on the electrode 100 or changing the conductivity as shown in the photo of FIG. 1 attached by various inorganic materials contained in water. Electrolyzed water could not be obtained.

In other words, there is a limit to obtaining more accurate electrolytic disinfection water due to the change in conductivity of various inorganic substances contained in water. As shown in the photograph of FIG. 1 , excessive scale S1 is formed between the electrodes 100 to prevent smooth electrolysis.

That is, the electrode reaction as described above is a reaction between the cathode and the anode, and when an electric current is applied to the electrode, hydrogen cations and oxygen gas are generated by the decomposition reaction of water at the positive electrode, and hydroxide ions are generated by the reduction reaction of dissolved oxygen at the negative electrode. , at a higher voltage, hydrogen gas and hydroxide ions are generated by the decomposition reaction of water as shown in [Reaction Equation 1] below.

[Scheme 1]

The hydroxide ions generated in [Scheme 1] react with bicarbonate ions contained in water to generate carbonate ions as shown in [Scheme 2] below.

[Scheme 2]

Here, in the precipitation step of the scale, as calcium carbonate or magnesium hydroxide is produced, carbonate ions generated by a cathodic reaction of the hardness component contained in water react with calcium ions in water to precipitate as calcium carbonate as shown in [Reaction Formula 3] below As a result, scale is attached to the electrode, and electrolytic sterilization water cannot be properly generated.

[Scheme 3]

In addition, when magnesium ions are present in the water, the hydride ions generated by the cathodic reaction react with the magnesium ions contained in the water as shown in [Reaction Equation 4] below to precipitate as magnesium hydroxide to form scale.

Here, the electrolysis tank 30 may be made of a single or a plurality, and the electrode may typically have a plurality of cathodes and anodes alternately installed, and the anode overcomes various problems caused by oxidation during electrolysis. For protection, an element having oxidation resistance, that is, a platinum group element is coated to protect, and the cathode may be used without coating an expensive platinum group element. However, when the polarity of the voltage is alternately applied, the anode may also be configured to be coated with a platinum group.

The water pretreatment unit 40 removes an obstacle to ion exchange in the water supplied from the water supply unit 20 , and includes a micro filter 41 and a carbon filter 42 .

The micro filter 41 is for primary filtering of solids (eg, sludge, organic matter, suspended matter, solid matter, soil, sand, etc.) included in the water, and the carbon filter 42 is the micro filter 41 ), which can be configured to secondary filter the chromaticity, turbidity, and odor of the water in which the solids are primary filtered.

Here, the control signal of the control unit 70 to control the supply of water to the water supply line on the water outlet side of the water supply unit 20 and the water supply side of the micro filter 41 included in the water pretreatment unit 40 . A first valve (V1) that is controlled to open and close may be formed in accordance with, and in the water supply line on the water receiving side of the electrolysis tank 30, to control the access of water that has been ion-exchanged by the ion exchange resin storage tank 50 The second valve V2 that is opened and closed according to the control signal of the control unit 70 may be formed.

That is, while the pressure gauge P1 is formed in the water supply line on the water outlet side of the water pretreatment unit 40 , the pressure gauge P1 supplies water filtered through the first and second stages by the water pretreatment unit 40 . Since the pressure is checked and provided to the control unit 70, the control unit 70 selectively selects the opening/closing state of the first and second valves V1 and V2 according to the pressure information of the pressure gauge P1.

or

It selectively exchanges cations, such as, and does not require an anion. The reason is that the anion contains a material rather necessary for generating an electrolytic disinfectant, and this is because it does not significantly affect the generation of electrode scale.

On the other hand, the cation exchange resin as described above has different selectivities depending on the type of cation during ion exchange, and when the concentration of cations is low, the exchange selection sequence is as follows.

를 이용하여 수지를 역세정시키는 방법으로 재생시킬 수 있도록 하였으며, 이는 상기 이온교환수지 재생장치(60)에 의해 이루어질 수 있는 것이다.At this time, when cations with low selectivity are captured by the ion exchange resin in which ions with high selectivity are captured, the ion exchange resin can be regenerated by contacting a large amount of ions with low selectivity, which is a salt of a saturated concentration, that is,

was used to regenerate the resin by a method of backwashing, which can be achieved by the ion exchange resin regenerating device 60 .

That is, the ion-exchange resin regeneration device 60 converts the ion-exchange resin, which is saturated with the ion-exchange action repeatedly performed in the ion-exchange resin storage tank 50, and the concentration of the ion-exchange resin with an ion regeneration solution as shown in the following [reaction formula 7]. It is to supply an ion regenerating agent (eg, salt or hydrogen chloride (HCl)) mixed with water to the ion exchange resin storage tank 50 to be regenerated by backwashing through the ion exchange resin.

Accordingly, the ion regenerating liquid is mixed with the water supplied to the ion exchange resin storage tank 50 with the ion regenerating agent discharged from the ion exchange resin regenerating device 60 connected to the water supply line, and the ion exchange resin storage tank (50) that can be put into the interior.

[Scheme 7]

Here, the operation format (concentration distribution) of the ion exchange resin can be explained by the attached FIG. 3 and the following [Scheme 8].

[Scheme 8]

On the other hand, in the water supply line on the water outlet side of the carbon filter 42 included in the water pre-treatment unit 40, a direction switching valve V4 whose opening direction is controlled by a control signal from the control unit 70 may be formed. In addition, the direction switching valve (V4) is the water pretreated by the water pretreatment unit (40) according to the control signal of the control unit (70) is injected into the ion exchange resin storage tank (50), and the ion exchanged water can be discharged to the electrolysis tank (30).

The ion exchange resin filter tank 80 has a filter network formed therein for filtering the ion exchange resin, which is formed in the water supply line between the ion exchange resin storage tank 50 and the electrolysis tank 30, This is to remove the ion exchange resin contained in the water when the water that is discharged from the ion exchange resin storage tank 50 by removing scale-inducing ions is supplied to the electrolysis tank 30, and accordingly, the electrolysis tank ( 30), only clean water can be supplied.

On the other hand, the disinfection water storage tank 90 is connected to the outlet line of the electrolysis tank 30 to store the electrolytic disinfection water, and after checking the level of the electrolytic disinfection water therein, the control unit 70 The water level sensor 91 provided to the can be formed.

Accordingly, the control unit 70 controls the opening and closing states of the first and second valves V1 and V2 included in the electrolytic disinfection water generating system according to the level information of the electrolytic disinfection water of the water level sensor 91, and the direction switching valve V4. ) of the direction change state, as well as the power supply state to the electrode in the electrolysis tank 30 can be controlled on or off.

That is, when the storage capacity of the electrolytic disinfection water sensed by the water level sensor 91 reaches a set capacity, the electrolytic disinfection water generation is stopped while controlling the overall operating state of the electrolytic disinfection water generation system off, and the disinfection water storage tank ( 90), when the level of the electrolyzed disinfectant water is lowered, the overall operating state of the electrolyzed disinfectant water generating system is turned on again.

Here, the third valve V3, which is opened and closed according to the control signal of the control unit 70, in the discharge line of the water outlet side of the disinfection water storage tank 90, and the third valve V3 when the third valve V3 is opened, the disinfection water storage tank ( A pump 92 for pumping the electrolytic disinfection water stored in 90 to the load side that requires it may be formed.

As described above, in the electrolytic disinfection water generating system having an electrode scale prevention function according to an embodiment of the present invention, as shown in FIGS. 2 and 3 , first, the first valve V1 is opened according to the control signal of the control unit 70 . When water is received from the water supply unit 20 to the water pretreatment unit 40 through the water supply line, sand, mud, and sludge are included in the water by the micro filter 41 included in the water pretreatment unit 40 . , and solids such as suspended matter are primarily removed, and color, taste, odor, etc. are removed by the carbon filter 42 included in the water pretreatment unit 40, and all obstacles to cation exchange with the water material can be removed.

Thereafter, the water passing through the carbon filter 42 is put into the ion exchange resin storage tank 50 , and at this time, the pressure gauge P1 checks the water outlet pressure of the water and transmits it to the control unit 70 .

Then, the control unit 70 selectively controls the opening and closing states of the first and second valves V1 and V2 while comparing the water outlet pressure checked by the pressure gauge P1 with the reference pressure, while the direction Since water is introduced into the ion exchange resin storage tank 50 through the direction change of the switching valve V4, the ion exchange action of the cations contained in the water in the ion exchange resin storage tank 50 is performed smoothly. .

That is, when the water that maintains a constant pressure is introduced into the ion exchange resin storage tank 50, the water reacts with the ion exchange resin stored in the ion exchange resin storage tank 50, and calcium ions contained in the water; Hard water components such as magnesium ions are removed by replacing them with sodium ions contained in the ion exchange resin.

On the other hand, when the cation contained in the water in the ion exchange resin storage tank 50 is removed by the ion exchange action, the control unit 70 turns the direction switching valve V4 to change the direction of the ion exchange resin storage tank 50 and Since the electrolysis tank 30 is communicated, water from which cations are removed by ion exchange in the ion exchange resin storage tank 50 can be discharged into the electrolysis tank 30 .

At this time, since the ion exchange resin sieve 80 having a filter network is connected to the water supply line connecting the ion exchange resin storage tank 50 and the electrolysis tank 30, the ion exchange resin sieve tank 80 ) is to filter the ion exchange resin from the water when the water is discharged to the electrolysis tank 30, and thus clean water from which the ion exchange resin has been filtered can be introduced into the electrolysis tank 30. .

Here, since the electrolyte stored in the electrolyte storage tank 10 is pumped and supplied to the electrolysis tank 30, when power is supplied to the electrodes in the electrolysis tank 30, in the electrolysis tank 30, the electrolyte and It is possible to generate electrolytic disinfection water by performing an electrolysis reaction of the water, as well as to prevent the formation of scale on the electrode.

That is, since scale-inducing ions are removed from the water injected into the electrolysis tank 30 , when the water causes an electrolytic reaction with the electrolyte to generate electrolytic disinfection water, the electrode is scaled as shown in FIG. 1 . is not created

Then, the electrolytic disinfection water generated in the electrolysis tank 30 flows into the disinfection water storage tank 90, and the level of the introduced electrolytic disinfection water is detected by the water level sensor 91 and then transmitted to the control unit 70. do.

Then, the control unit 70 controls the third valve V3 and the pump 92 according to the water level detection signal of the water level sensor 91, and the electrolytic disinfection water stored in the disinfection water storage tank 90 is required ( For example, a small-scale restaurant, plastic house, poultry farm, pig farm, etc.)

On the other hand, when the cations contained in the water in the ion exchange resin storage tank 50 are removed by the ion exchange action of the ion exchange resin, the sodium ions in the ion exchange resin are reduced and the hard water component of the water binds to the ion exchange resin. Therefore, the ability of the ion exchange resin is gradually lost.

That is, since the ion exchange resin is saturated and the concentration is lowered due to the ion exchange action repeatedly performed in the ion exchange resin storage tank 50, there is a need to regenerate it.

Accordingly, the ion-regenerating liquid is introduced into the ion-exchange resin storage tank 50 to regenerate the ion-exchange resin having a lower concentration, which is an ion-regenerating agent (eg, salt or hydrogen chloride (eg, salt or hydrogen chloride) in the ion exchange resin regeneration device 60 . HCl)) is made possible by supplying the water supply line on the water inlet side of the ion exchange resin storage tank 50 .

That is, when the ion regenerating agent supplied from the ion exchange resin regeneration device 60 is mixed with the water fed into the ion exchange resin storage tank 50, the ion regenerating agent mixed with the ion regenerating agent is added to the ion exchange resin storage tank 50. The input can be made, and accordingly, the ion exchange resin in the ion exchange resin storage tank 50 can be regenerated through backwashing.

Although the technical idea of the electrolytic disinfection water generating system having an electrode scale prevention function of the present invention has been described with the accompanying drawings, the best embodiment of the present invention is exemplarily described, and the present invention is not limited.

Therefore, the present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone skilled in the art without departing from the gist of the present invention as claimed in the claims.
