Description
The present invention relates to far-infrared radiation, deodorizing, antibacterial air purifier, far-infrared radiation, deodorizing, antimicrobial air purifier, including illite and maculite having oxygen-generating components and porous materials having deodorization and antibacterial functions, and far-infrared radiation functions. It is about.
Among the various pollution problems that are seriously raised both domestically and globally, air pollution, particularly the increase in the concentration of pollution gases such as carbon dioxide, carbon monoxide and sulfur oxides, has a very detrimental effect on public health. Even small amounts of air can cause headaches, breathing problems, asphyxiation, as well as a variety of adult diseases. Although the pollution caused by these gases is intensifying, various air purifiers manufactured and sold for general household or commercial use are mostly used for removing dust in the air, purifying air by releasing anions, or removing odors using activated carbon or humidification devices. It has only functions such as humidity control, and there is no air purifier or air purifier for removing acid gas and carbon monoxide, including carbon dioxide gas.
To increase the oxygen concentration in the air, there is an oxygen supply device used in a hospital emergency room, that is, a method using liquid oxygen contained in a high pressure bomb. However, since the oxygen storage container is a high pressure cylinder, it is heavy and dangerous and handles a high pressure container. It is not easy for the general public to use because there are inconveniences that require regular safety tests. In addition, there are oxygen generating devices by electrolysis, but the devices are too complicated, expensive, and inconvenient for use at home. Recently, there is a method of spraying oxygen by storing oxygen in a small low pressure container and breathing when athletes need a large amount of oxygen in an instant, but the amount and time of use are so small that they are not widely used. . In addition to the methods described above, chemicals may be used as oxygen sources for special purposes. For example, substances such as sodium chlorate generate oxygen by heating.
Recently, various studies have been conducted on how to remove formaldehyde, which is a factor of sick house syndrome. This is because formaldehyde is interpreted as a direct cause of sick house syndrome along with harmful organic substances and volatile organic substances. It is believed that one of the causes of children's asthma and atopic dermatitis, which is emerging as a social problem, is formaldehyde.
The easiest way to remove formaldehyde indoors is to ventilate it. However, there is a problem that natural ventilation has a weak effect of removing formaldehyde, and in many closed-type buildings, air conditioners are closed in summer and heaters are closed in winter, and ventilation is not easy. Moreover, overheating in the winter months can accelerate the release of lower aldehydes. Although it is possible to consider a method of forcibly ventilating the indoor air by using a ventilation facility, in this case, there is a disadvantage in that the installation of the device is expensive.
Thus, simple and inexpensive formaldehyde removal methods have been tried in various ways. The most widely used technique for removing formaldehyde is to use an adsorbent such as activated carbon. Activated carbon is a porous material with a very large surface area, which removes formaldehyde by physical adsorption. For example, Korean Patent Publication No. 2004-0035638 discloses a curtain using charcoal.
In addition to activated carbon, adsorption by loess has also been attempted. However, these adsorbents are difficult to fundamentally remove harmful substances and have disadvantages of low adsorption efficiency. In addition, formaldehyde adsorbed to an adsorbent such as activated carbon is not permanently removed, but once the adsorbed state is lowered in the formaldehyde concentration, it is characterized by being desorbed and released to the surroundings. In addition to activated carbon, it is known to use porous adsorbents such as activated clay, silica gel, and activated alumina, but these are also known to have low adsorption performance and problems in their persistence.
Therefore, an impregnated activated carbon may be used in which activated chemicals are impregnated with a chemical that reacts with formaldehyde. Impregnated activated carbon is activated carbon that reacts with the substance to be removed or reacted with the activated carbon. The activated carbon has a very strong removal performance for the target material, but it is expensive and has a limited amount of chemicals or catalyst attached to the activated carbon. The disadvantage is that the amount of material that can be removed is relatively small.
As one of the methods for removing formaldehyde, there is a removal method using an oxidation catalyst. In this case, a metal oxide is used as a catalyst, and titanium dioxide uses a principle of oxidatively decomposing lower aldehydes when subjected to ultraviolet rays, and is relatively useful in that lower aldehydes can be fundamentally removed by a chemical reaction. Although it can be done, where the amount of light is small, its performance is difficult to express, and in particular, there is a disadvantage in that titanium dioxide particles must be processed on a nano scale.
Referring to Korean Patent No. 10-0480808, a method of removing formaldehyde using an oxidizing agent such as sodium percarbonate is disclosed. The patent discloses a method for removing lower aldehydes including formaldehyde as a method of oxidizing hydrogen peroxide contained in sodium percarbonate. Is using. In this patent, relatively inexpensive sodium percarbonate is used as an oxidant to remove formaldehyde, which is excellent for removing formaldehyde in limited or confined spaces. However, the oxidizing power of sodium percarbonate is limited only to the surface of the grains of sodium percarbonate, so when all of the hydrogen peroxide on the surface portion is consumed, the removal efficiency drops sharply, and the oxidizing power is much lower than that of the hydrogen peroxide itself.
An object of the present invention is to provide far-infrared radiation, deodorizing, antibacterial air purifier that can remove the harmful gas and generate oxygen to improve the air quality.
Another object of the present invention is to provide a far-infrared radiation, deodorization, antibacterial air purifier having various functions such as far infrared radiation, deodorization, antibacterial, anion release, sterilization, water purification, cleaning function.
In order to achieve the above object, the present invention provides a far-infrared radiation, deodorizing, antimicrobial air purifier comprising an oxygen generating component and a porous material, and elite and macsumite.
In the present invention, the oxygen generating component may be one or a mixture of two or more selected from KO 2 , CaO 2 , Na 2 O 2, and Na 2 O 4 .
In the present invention, the porous material is a material having nano-sized pores made from vermiculite and fiolite.
Far-infrared radiation, deodorizing, antibacterial air purifier of the present invention may further include a catalyst, MnO 2 may be used as a catalyst.
Far-infrared radiation, deodorizing and antimicrobial air purifiers according to the first aspect of the present invention include KO 2 , a porous material, an illite and macsumite. Far-infrared radiation, deodorant, antimicrobial air purifiers of this embodiment may further comprise CaO 2 and / or MnO 2 .
Far-infrared radiation, deodorizing, antimicrobial air purifying agent according to the second embodiment of the present invention includes CaO 2 , a porous material, an illite and maculite, and may further include MnO 2 .
Far-infrared radiation, deodorizing, antibacterial air purifying agent according to the third embodiment of the present invention includes Na 2 O 2 , CaO 2 , porous material, illite and maculite, may further comprise MnO 2 .
Far-infrared radiation, deodorizing, antibacterial air purifying agent according to the fourth embodiment of the present invention includes Na 2 O 4 , CaO 2 , porous material, illite and maculite, may further comprise MnO 2 .
Far-infrared radiation, deodorizing, antibacterial air purifier of the present invention can remove the harmful gas and generate oxygen to improve the quality of the air, far infrared radiation, deodorization, antibacterial, anion release, sterilization, water purification, cleaning functions, etc. Has
Far-infrared radiation, deodorizing, antibacterial air purifier of the present invention includes oxygen generating components and porous materials and illite and maclite, specifically, 50-98 wt% oxygen generating components, 1-49 wt% porous materials, 0.5- illite 48 wt% and 0.5 to 48 wt% of macsumite. When using less than 50% by weight of the oxygen generating component has the disadvantage of reducing the ability to purify the air and decrease the air purification effect. Therefore, the amount of the oxygen generating component is preferably 50 to 98% by weight. When using less than 1% by weight of the porous material can not obtain functionality such as deodorization, antibacterial function, when using more than 49% by weight may reduce the oxygen generating effect. Therefore, the amount of porous material is preferably 1 to 49% by weight. If the content of illite and macsumite is too small, functionality such as far-infrared radiation cannot be obtained, and when too much, the oxygen generating effect may be reduced. Therefore, the amount of illite and macsumite is preferably 0.5 to 48% by weight, respectively.
In the present invention, the oxygen generating component may be one or a mixture of two or more selected from KO 2 , CaO 2 , Na 2 O 2, and Na 2 O 4 . The oxygen generating component reacts with moisture and carbonic acid at room temperature to generate oxygen as shown in Chemical Formulas 1 to 6 below. That is, carbon dioxide is removed and oxygen is generated at the same time. In addition, the oxygen generating component removes formaldehyde as shown in the formula (7). Specifically, oxygen generated in Chemical Formulas 1 to 6 according to Chemical Formula 7 oxidizes formaldehyde to formic acid. In this case, in the case of using a catalyst, in particular MnO 2 , not only oxygen generation is increased, but also the oxygen generation rate can be stably maintained.
In the case of KO 2 , the theoretical value of the amount of pure oxygen generated by the chemical formula is 234 cc / g. If 60 g of KO 2 is a 100% chemical reaction, 234 ㅧ 60 g = 14,040 cc (about 14 L), and the oxygen concentration of normal air is about 20%, so 14 L ㅧ 5 = 70 L It becomes possible.
In the present invention, the porous material is a material having nano-sized pores made from vermiculite and fiolite. Specifically, the porous material is composed of 10 to 90% by weight vermiculite and 10 to 90% by weight of zirconia, and the pore size is 1 to 1,000 nm, preferably 10 to 100 nm.
The porous material of the present invention may be a natural inorganic material such as heulandite (Ca, Na 2 (Al 2 Si 7 O 18 ) .6H 2 O); Vermiculite: (Mg, Fe, Al) 3 (Al, Si) · 4O 10 (OH) 2 · 4H 2 O) is made of 100% natural products such as inorganic polymers, which are harmless and harmless to humans. It is a new material and inexpensive compared to existing products, and it has a continuous effect as a polar porous crystal of fine porosity, and has various functions such as deodorization, antibacterial, sterilization, water purification, and washing function.
The porous material of the present invention can be produced in a gel form through a mixing process, a drying process, and the like of the raw material and water; It can be produced in soft and hard form through mixing, compression, spinning, and baking.
The porous material of the present invention is a piezoelectric and pyroelectric polar crystal (TM 0.06 mA) capable of ion exchange (2 L selective adsorption (N, C) / substituted) of molecular function, catalyst (nonpolar molecular adsorption / separation / discharge), antibacterial agent ( Food poisoning bacteria: Staphylococcus aureus) acts as a deodorant, purifies and cleans water (ammonia, nitrogen, phosphorus, formaldehyde), and adsorbs and removes VOC, HCHO and heavy metals.
Illite is a mica-like mineral belonging to a monoclinic system, and its chemical composition is (K, H 3 O) Al 2 (Si, Al) 4 O 10 (H 2 O, OH) 2 . In terms of chemical composition, SiO 2 , MgO, H 2 O are relatively high, and K 2 O is low. Hardness 1-2 and specific gravity 2.6-2.9. Cleavage is complete with 001, streaks white, earthy luster. It is produced in aluminium-rich heterogeneous or tuff sedimentary rocks, and is produced as an altered mineral of hydrothermal deposits. Illite has the effect of far-infrared radiation, anion release, deodorization and the like.
Macsumite is a natural mineral that contains a large amount of hornblende in gantherite. It is a compound word of gantholite and hornblende, and far-infrared rays of the organic compound absorption wavelength band are radiated more than 90%. Far-infrared rays are emitted to all the minerals, and it was confirmed that elvan has more far-infrared radiation than other minerals. However, in order to benefit the human body and organic compounds, far infrared rays of 8 to 11 μm should be emitted. Most minerals do not have a great influence on the human body because the far-infrared emissivity drops sharply in the human body and the organic compound wavelength band. In order for the far-infrared rays to be emitted in this range, it is necessary to use the macsumite containing the hornblende properly. In addition to the far-infrared radiation effect described above, the macsumite has effects such as antibacterial and deodorization.
Far-infrared radiation, deodorizing, antimicrobial air purifier of the present invention may further include a catalyst, MnO 2 , copper oxide, peroxidase, catalase and potassium iodide, etc. may be used as the catalyst, among which MnO has high chemical stability. 2 is most preferred. If the amount of the catalyst is less than 0.01% by weight, the ability to purify the air is reduced and the air purification effect is reduced.When the amount of the catalyst is used more than 25% by weight, the difference in the amount of change in formaldehyde and carbon dioxide removal and the amount of change in oxygen generation are different. There was little. Therefore, considering the production cost, the amount of the catalyst is preferably 0.01 to 25% by weight.
