Description

Air cleaner using electrolysis {Airwasher using Electrolysis}

The present invention relates to an apparatus for purifying air by electrolyzing water to make sterilized water including a mixed oxidant and making micro water with the sterilized water and contacting with contaminated air. More specifically, a reactor for electrolyzing water is provided. And electrolysis of water in the reactor to produce microwater containing mixed oxidant and to clean the microwater containing mixed oxidant and contaminated air in or out of the container.

The electrochemical process of electrolyzing water as an alternative to chlorine disinfection in waterworks is actively underway. Disinfection using the electrochemical method is an environmentally friendly process in that electrons are used unlike conventional disinfection methods using chemical disinfectants. In addition, the process is easy to automate, the operating cost is low, and mixed oxidants such as O ₃ , H ₂ O ₂ , OH (OH radical) and HOCl (hypochlorous acid) are produced simultaneously with chlorine to remove disinfection effect and organic matter. There is an advantage that it can.

The use of these electrochemical methods for air purification requires techniques to produce sterilized water with higher concentrations of mixed oxidants.

In addition, since general air cleaners use water, secondary pollution may occur due to water contamination due to contact with contaminated air, and inconvenience of having to change water frequently to prevent ancillary contamination of the air cleaner's bucket. there was.

Therefore, the present invention was invented to solve the conventional problems as described above, using the electrode according to the object of the present invention, including HClO (hypochlorous acid) excellent in sterilization power even if the reaction space and the reaction time to reduce the electrolysis occurs The present invention provides a device for purifying contaminated air in and out of a container by making sterilized water of mixed oxidant and using natural humidification using a vibrator or wheel disk.

According to a feature of the present invention for achieving the above object, the present invention is at least a pair of electrodes, the oscillator, a wheel disk by a method of making a micro water and a power supply for applying power to the pair of electrodes In the air humidifier using a sterilizing water containing a mixed oxidant, characterized in that selected from the injection using a pump or a combination thereof, the power supply unit control panel or operation button for applying power to the pair of electrodes It may be provided with, it is possible to switch the direction of the electrode supplied to the pair of electrodes through the control panel.

According to the air cleaner using the electrolysis according to the present invention it can be expected the following effects.

That is, in the air purifier of the present invention using the electrolytic decomposition of the water to the mixed oxidant and using the sterilized water in contact with the contaminated air in the form of micro water through a vibrator, a wheel disk, a spray using a pump or a combination thereof Therefore, not only the function of purifying sterilization but also the function of humidification was implemented.

1 is a block diagram showing a schematic configuration of an air cleaner using electrolysis in which a pair of electrodes are installed in a reaction tank composed of an air suction fan, a vibrator, a wheel disk, a pump, and a nozzle according to a specific embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the air cleaner using the electrolysis according to the present invention as described above will be described in detail.

As shown in FIG. 1, an air cleaner using electrolysis according to a specific embodiment of the present invention includes a reaction tank having a component selected from the group consisting of an air suction fan, a vibrator, a wheel disk, a pump, a nozzle, or a combination thereof. It is configured to include a pair of electrolysis electrodes installed in.

The reaction tank is configured to include at least one pair of electrodes to cause an electrolysis reaction. The electrolysis reaction occurs when a direct current is supplied to the pair of electrodes. The DC current is supplied through the DC power jack 80.

In the air purifier using the electrolysis according to a specific embodiment of the present invention, it has been described that the DC current is supplied by the DC power jack 80, the electrolysis reaction occurs by supplying the DC power to the electrode.

DC power supplied to the pair of electrodes is controlled by the PCB. And an operation button for driving the PCB. In addition, in order to solve the problem of erosion of the electrode can be alternately supplied through the PCB to the direction of the current.

In general electrolysis of water, ozone and hydrogen peroxide are generated by the oxidation reaction at the anode and the reduction reaction at the cathode as follows.

[Anode, Anode]

H ₂ O ⇒ H ⁺ + (OH) _ads + E ^-

(OH) _ads ⇒ (O) _{ads ^{or O 2 + H + + e}} -

(O) _ads + O ₂ ⇒ O ₃

Cathode

O ₂ + 2H ⁺ + 2e ^- ⇒ H ₂ O ₂

OH radicals are partly HO ₂ when the H ₂ O ₂ to react with the water in the weak ^acid-as dissociated (hydroperoxide ion) is generated as follows.

_{H 2 O 2 + H 2 O} ⇔ HO 2 - + H 3 O -

O ₃ + HO ₂ ^- ⇒ ⊙OH + O ₂ ^- + O ₂

O _{3 ^{+ O 2 - ⇒ O 3 -}} + O 2

_{^{O 3 - + H + ⇔ ⊙HO}} 3

⊙ HO ₃ ⇒ OH + O ₂

The oxidation of O ₃ in water is largely divided into the direct reaction by O ₃ molecules and the indirect reaction of OH radicals produced by the decomposition of O ₃ .

In summary, O and O ₂ formed by electrolysis of water The molecules combine to form ozone. Next, hydrogen peroxide is produced by the electrolysis of oxygen or by the bonding of OH radicals, which are intermediate products produced by the decomposition of ozone.

After Cl ⁻ ions present in water bind with Cl _2, they react with H ₂ O to generate HOCl.

The OH radical is if the direct measurement is not possible, but the ozone due to disappear was instantaneously present in the water, OH ^- or the conjugate base of HO ₂ of the hydrogen ^{peroxide-forming} a and radical chain cycle reaction, and finally the OH To generate radicals.

Microorganisms in contact with the sterilizing water are inactivated or removed by the resulting mixed oxidant. That is, bacteria are removed by electrosorption and other microorganisms are removed by direct electrolysis by reaction with e ⁻ . Looking at this in more detail, it is as follows.

(Scheme 1)

Microorganism ⇒ Electrosorption ⇒ Inert

M + O ₃ ⇒ Inactivaton

M + OH ^- ⇒ Inactivaton

M + HOCl ⇒ Inactivaton

(Scheme 2)

Microorganisms (Microorganics) e ^- ⇒ M ^-

M + O ₃ ⇒ Product

M + OH ^- ⇒ Product

M + HOCl ⇒ Product

That is, the oxidizing and sterilizing action is performed smoothly by the mixed oxidants (O ₃ , H ₂ O ₂ , HOCl, OH radicals) generated during the electrolysis of water. After the electrolysis is made, sterilized water is maintained by high residual HOCl (hypochlorous acid) and anion to maintain high sterilizing power.

As described above, according to the air purifier using the electrolysis according to a specific embodiment of the present invention, the sterilized water containing the mixed oxidant has the advantage of having the ability to purify the contaminated air while maintaining its function in the state of micro water. have.
