Description

Disinfection-type air purification system [0002]

More particularly, the present invention relates to an anti-pollution air purification system capable of purifying air contaminated with positive and negative ions generated in a bipolar ionizer and eliminating pests by an ultrasonic generator.

The demand for environmental products such as air purifiers is continuously increasing due to interest in yellow sand, air pollution, well-being, and sick house syndrome.

BACKGROUND ART [0002] Generally, an air purifier is a device for creating a pleasant indoor environment by removing impurities such as various dusts, gases, odors, and smoke contained in air, and includes a casing having an inlet and an outlet.

The casing is provided with an air blowing device for introducing air into the casing through the suction port and again supplying the air to the outside of the casing through the discharge port. The dust and dirt in the air introduced into the casing And a filter device for filtering odor components.

The filter device includes a pre-filter arranged to primarily filter relatively large dust, a dust filter configured to collect fine dust that has passed through the pre-filter, a deodorizing filter provided to filter odorous components in the air, , And an antibacterial filter for treating microorganisms such as viruses or fungi.

As the dust collecting filter, an electric dust filter using ionization phenomenon of dust particles or a high efficiency particulate air (HEPA) filter made of a nonwoven fabric type filter fabric made of an asbestos fiber is used. As the deodorizing filter, An activated carbon filter for adsorbing a component, a photocatalytic filter for removing bacteria together with an odor component, and the like are used.

When the air blowing device is operated through such a configuration, the air introduced into the casing through the suction port sequentially passes through various filters constituting the filter device, and then is discharged to the outside of the casing through the discharge port. In this process, the dust and odor component And the like are removed.

However, in a conventional air purifier, a filter device installed inside a casing may not be able to function properly due to clogging or performance deterioration when it is used for a long period of time. In order to prevent the filter device from being cleaned or periodically replaced There is a hassle to do.

For example, the prefilter should be cleaned and used after drying, and dust filters and deodorization filters should be replaced periodically (for example, every one year).

Recently, it has been confirmed that the antimicrobial filter contains octyl isothiazoline (OIT), a toxic substance commonly used as an inhibitor of microbial growth inhibiting bacteria and fungi, killing general users. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

It is to be noted that the same components of the drawings are denoted by the same reference numerals and symbols as possible even if they are shown in different drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Also, when a part is referred to as "including " an element, it does not exclude other elements unless specifically stated otherwise.

FIG. 1 is a block diagram of a sanitary air cleaning system according to an embodiment of the present invention.

1, the air-purifying system according to the embodiment of the present invention includes a power supply unit 10, a bipolar ionizer 20, a blowing fan 30, an ultrasonic generator 40, and a detector 50. [ .

 The power supply unit 10 includes a single integrated board, receives AC power for general commercial use, converts AC into DC required for operation of the bipolar ionizer 20 and DC required for operation of the ultrasonic generator 40, and outputs the DC.

When the bipolar ionizer 20 applies AC currents of several tens mA to the positive and negative electrodes 21 and 22 provided on both sides of the product, The covalent bonds with the water vapor in the air dissociate and the anions such as peroxide ions (O ₂ ^- ), excess oxidizing ions (O ₂ ^2- ), hydroxyl radicals (OH *), (VOCs), bacteria, viruses, bacteria, fungi, formaldehyde (HCHO) and fine dusts as shown in FIG.

The peroxide ions (O ₂ ^- ), the excess oxidizing ions (O ₂ ^2- ), and the hydroxyl radicals (OH *) completely decompose the carbon-hydrogen bonds and carbon-carbon bonds of formaldehyde and organic compounds into strong reactivity, The charge generated momentarily on the surface of the dust is attracted to the electrostatic attraction using strong (+) and (-) charges, and the particle size is enlarged to several hundreds to several thousands times, so that the mass is small, Lt; / RTI >

In addition to the complete removal of the secondary pollutants, no ozone is generated and no harmful human body is circulated in the indoor space to provide a refreshing sensation ("Spray and Electrification of Sub-micron Particles Charged by Corona Discharge Volume distribution ", Transactions of the Korean Society of Mechanical Engineers, Vol. B, Vol. 25, No. 1)

The ultrasonic generator 40 receives DC power (for example, DC 12V) from the power supply unit 10 and generates ultrasonic waves by the ultrasonic vibration and oscillation unit provided therein to radiate the ultrasonic waves through the speaker 42.

At this time, the frequency is heard at a non-audible frequency, for example 27,000 Hz to 40,000 Hz, which can not be heard by humans, such as rats, cockroaches, ants and ticks, and the radiation method is to radiate indiscriminate irregular, do.

Also, the speaker 42 is composed of a radial piezo speaker.

The detection unit 50 measures the concentrations of the carbon dioxide (CO ₂ ) gas and the sulfur oxide (SO _x ) gas present in the air in the sensors 54a and 54b and outputs them to the microcomputer 56. The microcomputer 56 detects the concentration of carbon dioxide The lamps 52 are turned on or off in different colors according to the concentrations of carbon dioxide (CO ₂ ) and sulfur oxides (SO _x ).

The carbon dioxide (CO ₂₎ sensor 54a measures the carbon dioxide concentration by measuring the degree of absorption of infrared rays using, for example, the principle that carbon dioxide absorbs only infrared rays of a specific wavelength, or measures the concentration of carbon dioxide To measure the carbon dioxide concentration.

SO _x such as SO ₂ and SO ₃ is a typical harmful gas generated by automobile exhaust pipes and boilers and causes not only air pollution but also acid rain. Therefore, detection of SO _x gas is one of the most important factors It is one.

The SO _x The sensor (54b), for example, measuring the amount of SO _x gas to the sensing electrode from the electromotive force caused by contact with SO _x.

If the microcomputer 56 determines that it is safe according to the measurement concentration of the carbon dioxide and the sulfur oxide, the microcomputer 56 emits the lamp 52 in green, for example, And if it is judged to be dangerous, the lamp 52 emits red light, for example.

At this time, a plurality of lamps 52 may be provided for each color to emit light. In the present invention, one lamp is composed of RGB LEDs emitting various colors.
