Abstract
Description
The present invention relates to a deodorizing antimicrobial air purifier, and to a deodorizing antimicrobial air purifier comprising an oxygen generating component and a porous material having deodorization and antibacterial functions.
Among the many 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 the 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 carbon dioxide and acid gases and carbon monoxide.
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 storing oxygen in a small low-pressure container and spraying it to breathe when athletes need a large amount of oxygen momentarily, 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 together with HOC's and volatile organic substances (VOC's). One of the causes of children's asthma and atopic dermatitis, which is emerging as a social problem, is formaldehyde. It is believed to be aldehyde.
The easiest way to remove formaldehyde indoors is to ventilate it. However, natural ventilation has a weak effect of removing formaldehyde, and in many closed buildings, air conditioners are used in summer and heaters are closed in winter, so ventilation is not easy. In addition, overheating in the closed winter season 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, in order to compensate for the disadvantages of the adsorbent, impregnated activated carbon may be used in which an activated carbon is 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 activated carbon.Although the target material shows very strong removal performance, it is expensive and it is actually removed because of the limited amount of chemicals or catalysts attached to the activated carbon. The disadvantage is that the amount of material that can be made 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 a 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 deodorizing antimicrobial air purifier having various functions such as deodorization, antibacterial, sterilization, water purification, cleaning function.
In order to achieve the above object, the present invention provides a deodorizing antimicrobial air purifier comprising an oxygen generating component and a porous material.
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.
The deodorizing antimicrobial air purifier of the present invention may further include a catalyst, and as the catalyst, MnO 2 may be used.
The deodorizing antimicrobial air purifier according to the first embodiment of the present invention includes KO 2 and a porous material. Deodorizing antimicrobial air purifiers of this aspect may further include CaO 2 and / or MnO 2 .
The deodorizing antimicrobial air purifier according to the second embodiment of the present invention includes CaO 2 and a porous material, and may further include MnO 2 .
The deodorizing antimicrobial air purifier according to the third embodiment of the present invention includes Na 2 O 2 , CaO 2, and a porous material, and may further include MnO 2 .
The deodorizing antimicrobial air purifier according to the fourth embodiment of the present invention includes Na 2 O 4 , CaO 2, and a porous material, and may further include MnO 2 .
The deodorizing antimicrobial air purifier of the present invention can improve the air quality by removing harmful gases and generating oxygen, and has various functionalities such as deodorization, antibacterial, sterilization, water purification, and washing functions.
The deodorizing antimicrobial air purifier of the present invention includes an oxygen generating component and a porous material, and specifically, may be composed of 50 to 99 wt% of the oxygen generating component and 1 to 50 wt% of the porous material. 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 oxygen generating component is preferably 50 to 99% 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 50% by weight may reduce the oxygen generation effect. Therefore, the amount of porous material is preferably 1 to 50% by weight.
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 carbon dioxide gas 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. When 60 g of KO 2 caused a 100% chemical reaction, 234 ㅧ 60g = 14,040 cc (about 14L), and the normal oxygen concentration was about 20%, so it could absorb 14L ㅧ 5 = 70L of air.
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 (2L selective adsorption (N, C) / substitution) 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.
The deodorizing antimicrobial air purifier of the present invention may further include a catalyst, and as the catalyst, MnO 2 , copper oxide, peroxidase, catalase, potassium iodide, etc. may be used, and MnO 2 having high chemical stability is most preferable. . 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.
