Description

Air purification module {Air filter module}

The present invention relates to an air purification device module that absorbs, adsorbs, decomposes, and removes carbon dioxide (Co2), VOCs, and greenhouse gases contained in the air, and also maintains a purification function even after long-term use, so that maintenance costs are very low.

The occurrence and frequency of fine dust are increasing due to various reasons such as industrial development, urbanization, and especially the influence of yellow dust from China. As the concentration of fine dust in the air rapidly increases, not only does the incidence of disease increase, but also massive damage occurs in the industry. According to data from the Korea Environment Institute, fine dust causes a total loss of up to 5 trillion won per year in human lives and industry.

Fine dust generated from power plants, automobiles, and industrial sectors is reaching a serious level that it is directly affecting the health of the people. Accordingly, policies to reduce fine dust generation are being promoted domestically and internationally. Reducing fine dust generation is the top priority, and removing the fine dust generated is also important to prevent it from affecting people’s health.

In particular, fine dust such as yellow dust cannot be reduced through reduction policies and technologies alone. Therefore, the development of technologies to remove the fine dust that has been generated is very important.

The development of technology to remove fine dust, which has a negative impact not only on industry but also on all aspects of life, is very important. Currently, various filter systems (bag filters, electric precipitators, HEPA filters, etc.) are being applied, but these filter systems have limitations in removing the increasing amount of fine dust.

In particular, ultrafine particles with a size of 0.1㎛ or less, particles with a size of 0.1 to 1.0㎛, and fine particles with a size of 1 to 10㎛ are distributed in the atmosphere.

Depending on the distribution of each particle, the filter method is different, and it is very difficult to remove ultrafine particles, and particles less than 10㎛ can be removed with a high-performance filter such as a HEPA filter.

However, these HEPA filters are used to remove particles in high-cleanliness spaces such as clean rooms, and operating these filters requires high costs.

Additionally, as the importance of the environment increases, technologies are being developed to capture and store greenhouse gases, which are the cause of global warming.

In particular, chemical absorption, adsorption, membrane separation, and deep-freezing methods are being used and developed as methods to reduce carbon dioxide (Co2), an acid gas among greenhouse gases, and VOCs. The chemical absorption method uses an absorbent to absorb and remove carbon dioxide, and is the most widely used due to its high efficiency and stable process.

The carbon dioxide absorption process using the above chemical absorbent and the regeneration process of the absorbent are basically equipped with an absorption tower and a stripping tower.

The above absorption tower is supplied with flue gas containing carbon dioxide and an absorption liquid, and absorbs the carbon dioxide in the flue gas into the absorption liquid through a chemical reaction. In addition, the flue gas from which carbon dioxide has been removed is discharged from the top of the absorption tower, and the carbon dioxide-containing absorption liquid that has absorbed carbon dioxide moves to the bottom of the absorption tower and is transferred to the stripping tower.

This is called the carbon dioxide absorption process. In addition, the stripping tower heats the carbon dioxide-containing absorption liquid to separate carbon dioxide from the absorption liquid. The carbon dioxide separated from the absorption liquid is discharged from the top of the stripping tower, and the absorption liquid from which carbon dioxide has been separated is transported to the absorption tower and reused. This is called the stripping process or the absorption liquid regeneration process.

The process of removing carbon dioxide from the carbon dioxide-containing absorbent in the above-mentioned stripping tower is performed at a high temperature of 100 to 140°C, and a lot of heat energy is consumed to maintain this temperature.

There is a need for the development of an absorption solution and related processes to reduce the energy consumed in the above carbon dioxide absorption and removal processes.

To this end, energy is recovered by heat exchange between the absorbent liquid that has absorbed carbon dioxide in the absorption tower and the high-temperature absorbent liquid from which carbon dioxide has been separated by heating in the stripping tower.

However, conventional technology has limitations in energy recovery because it recovers heat through simple heat exchange between the absorbent that absorbs carbon dioxide and the absorbent that separates carbon dioxide.

In particular, if the capacity of the heat exchanger is excessively designed to maximize energy recovery, the absorbent liquid that has absorbed carbon dioxide is separated into gas (carbon dioxide) and liquid (absorbent liquid) in the heat exchanger, which not only prevents smooth heat exchange, but also causes a problem in that the flow rate cannot be controlled due to the separation of gas and liquid in the pipe.

In addition, conventional air purification technology frequently causes backflow by stacking activated carbon inside a tank and forcibly exhausting the air, and the pressure inside the tank increases, which can cause the dust collector to explode.

In addition, the deodorizing phenomenon occurs only in front of the activated carbon piled up inside the tank, so the deodorizing effect is low, and the deodorizing function only deodorizes the bad smell in a short period of time, so there is a problem that the deodorizing efficiency is low.

In addition, the after-care and installation costs for replacing activated carbon are excessive, which adds to the economic burden.

Therefore, in order to remove carbon dioxide, VOCs, fine dust and ultrafine dust that flow into or are generated in homes, offices, restaurants and other businesses, factories, etc., an air purifying device that overcomes the limitations of existing filtering methods such as non-woven fabrics and electric precipitators and can remove carbon dioxide, antibacterially and deodorize in addition to removing fine dust is needed.

In order to achieve the above purpose and effect, the present invention is described in detail with reference to the attached drawings as follows.

FIG. 1 is a perspective view illustrating an air purification device module of the present invention, and FIG. 2 is a cross-sectional view illustrating an air purification device module of the present invention.

The air purification device module of the present invention is excellent in absorbing, adsorbing, decomposing and reducing carbon dioxide (Co2), VOCs and greenhouse gases contained in the air, and in removing odors, contaminants such as infectious disease bacteria and yellow dust.

The above air purification device module (1) is largely composed of a housing, a first filter section (9), a UV-C lamp (15), a second filter section (9), a third filter section, a UV-C lamp (15'), a fourth filter section (12), and an ultraviolet filter (13).

The housing of the above air purification module (1) has an intake port (2) for sucking in air and an outlet port (3) for discharging purified air formed on the upper surface, and a partition plate (4) is installed vertically inside to isolate the intake port (2) and the outlet port (3), and a first filter chamber (5) and a second filter chamber (6) are formed on one side of the partition plate (4), and an air passage (7) is formed at the bottom of the partition plate (4) to connect the first and second filter chambers (5, 6).

In the first filter room (5) above, the first filter section (9) installed below the intake port (2) is formed into a ball shape by mixing activated carbon, zeolite, titanium dioxide, potassium dioxide, gellite, and volcanic rock to purify the intake air, and then fired at high or low temperature to complete the ball-shaped adsorption filter, thereby adsorbing harmful substances including carbon dioxide.

A UV-C lamp (15) is installed at the bottom of the first filter section (9) to promote photocatalysis of the first filter section (9) and the second filter section (10) by wavelength.

A second filter section (10) is installed at the bottom of the above UV-C lamp (15) to purify the inhaled air. Activated carbon, zeolite, titanium dioxide, potassium dioxide, gellite, and cypress yellow are mixed and formed into a ball shape, and then fired at high or low temperature to complete the ball-shaped adsorption filter, thereby adsorbing harmful substances including carbon dioxide.

The air purified in the second filter section (10) moves to the lower part of the second filter room (6) through the air passage (7) located at the bottom, and the third filter section (11) installed at the upper part of the air passage (7) adsorbs harmful substances, including carbon dioxide, through a ball-shaped adsorption filter formed by mixing activated carbon, zeolite, titanium dioxide, cypress yellow clay, and ceramics into a ball shape and then firing it at high or low temperature.

A UV-C lamp (15') is installed on the upper part of the third filter section (11) to promote photocatalysis of the third filter section (11) and the fourth filter section (12) by wavelength.

A fourth filter section (12) is installed on the upper part of the above UV-C lamp (15'), and carbon dioxide and other harmful substances are adsorbed by the ball-shaped adsorption filter formed by mixing activated carbon, zeolite, titanium dioxide, loess, and ceramics and sintering them at high or low temperatures to form a ball-shaped adsorption filter.

A Ulpa filter (13) is installed on the upper part of the fourth filter section (12) to remove ultrafine dust and sterilize viruses.

An exhaust fan (14) is installed on the upper part of the above-mentioned Ulpa filter (13) to exhaust purified air to the outside.

Activated carbon, zeolite, titanium dioxide, and potassium dioxide gellite powder that have gone through a refining process, which are commonly mixed in the above 1st, 2nd, 3rd, and 4th filter sections, are mixed and formed into a ball shape, and then subjected to a high-temperature or low-temperature sintering process to manufacture an adsorption filter, which adsorbs carbon dioxide and VOCs and changes the adsorbed carbon dioxide (Co2) into water and oxygen, and potassium dioxide has the function of adsorbing carbon dioxide and converting it into water and oxygen.

Therefore, the adsorption filters of the 1st, 2nd, 3rd, and 4th filter sections are formed into a spherical ball shape by impregnating potassium iodide (stable iodine) powder to maximize the desired air flow and adsorption power, thereby improving the efficiency as an adsorption filter and maintaining the adsorption filter even after long-term use.

In addition, a catalytic method using manganese dioxide was used to promote the reaction speed of the adsorption filters in the first, second, third, and fourth filter sections. Manganese dioxide has catalytic properties and is therefore widely used as a catalytic agent.

Therefore, the photocatalytic effect is maximized by using the wavelengths of 385 nm, 185 nm, and 253.7 nm generated from UV-C lamps (15, 15') depending on the efficiency of titanium dioxide.

In addition, activated carbon powder is mixed with zeolite mineral material and processed through low-temperature firing at around 150 to 300℃ to strengthen the original adsorption, absorption, and organic matter decomposition functions of activated carbon (carbon), and titanium dioxide is mixed and molded here, and harmful substances and odors are simultaneously deodorized under a UV-C lamp (amalgam lamp) (15, 15').

In addition, as another embodiment, a high-temperature calcined activated carbon powder and a multiporous mineral powder such as a ceramic powder or a zeolite powder are mixed and processed by high-temperature calcination at about 700 to 1,000°C, and harmful substances and odors are simultaneously deodorized under a UV-C lamp (amalgam lamp) (15, 15').

Meanwhile, activated carbon is a filtering agent with a large specific surface area, making it an essential material for adsorbing various hazardous substances. It is a material that has developed even finer pores through an activation process using carbon as a raw material.

Activated carbon has a large internal surface area of about 1,000㎡ per gram, and has the property of adsorbing molecules of the adsorbed substance by applying a pulling force to the surrounding liquid and gas with the functional groups of the carbon atoms. It has the best adsorption power among existing natural substances, and is used for eliminating sick house syndrome and purifying the air. Since it is a thousand-year-old ingredient and harmless to the human body, it is excellent for air purification, removing sick house syndrome, mold, deodorization, catalyst, and carrier functions.

In addition, natural zeolite, ceramic, and UV-C lamps have excellent physical adsorption and chemical cation substitution effects, and have the ability to absorb, adsorb, store, and then release substances other than moisture, such as gases, up to 20 times, so they have excellent adsorption effects.

In addition, titanium dioxide is a substance that adsorbs organic substances and, when exposed to light, reacts with the previously adsorbed organic substances to cause a photocatalytic reaction, sufficiently compensating for the shortcomings of photocatalysis while adsorbing and decomposing more organic substances.

Additionally, titanium dioxide is an eco-friendly material that is harmless to the human body and transforms various pollutants into substances that are harmless to the human body.

In addition, UV-C lamps (amalgam lamps) are harmless to the human body with light wavelengths of 235.7 nm and 184.9 nm, and are light that causes photosynthesis in plants. When they react with titanium dioxide, a photoelectron (low-temperature plasma) phenomenon occurs, forming a powerful low-temperature photoplasma of 30,000 volts and separating the air into negative ions and pure oxygen and hydrogen.

In addition, among pozzolans, Gelrite is a representative pozzolan with a germanium content of 2.0 ppm, contains a large amount of far-infrared minerals, and has a component effect 187 times higher than that of yellow soil. It is an environmentally friendly material mineral that is widely used in all fields such as environmental improvement agents and medicine, and has deodorizing effects, removing harmful substances, neutralizing heavy metals, and suppressing radon and formaldehyde.

Therefore, the air purification device module of the present invention maintains its purification function even after long-term use, and thus has very low maintenance costs, reducing the economic burden and allowing it to be installed and used in homes, offices, businesses such as restaurants, and factories.

In addition, the air purification device module (1) can be manufactured in a module type and installed in a dust collector.
