Description

High efficiency deodorization and air sterilization apparatus using advanced oxidation process and its method {Apparatus and Method of High Efficiency Deodorization and Air Sterilization using Advanced Oxidation Process}

The present invention relates to an air purifier, and to an air sterilization and deodorization device that provides a beneficial environment for the human body by improving the sterilization and deodorization efficiency while reducing the amount of residual ozone.

The air purification structure for sterilizing and deodorizing polluted air includes a filter method using a filter having high adsorption of harmful substances such as activated carbon, an ultraviolet radiation method that emits sterilizing ultraviolet rays, and ozone that emits ozone having sterilization and deodorization properties. Emission systems or mixing systems in which these are combined are used.

Examples of a mixed method in which the ultraviolet irradiation method and the ozone emission method are applied are disclosed in Korean Utility Model Registration No. 0182607, Korean Utility Model Registration No. 0265613, and Korean Utility Model Registration No. 0329780.

In general, ozone (O 3) is a fuselage of pure oxygen, which generates ozone by electric silent discharge and blows it into water, or when used in air, has strong sterilization and oxidizing power. Therefore, it decomposes harmful heavy metals and sterilizes infectious pathogens within seconds. It is a gas which returns to dissolved oxygen in water again.

As mentioned above, ozone is an unstable gas, which is highly chemically active, which causes bacteria, viruses, fungi, odors, various harmful gases in the air and water, and organic substances harmful to the human body (solvents, pesticides, heavy metals, etc.). Attack and chemically react with them to oxidize. This property is used to make air or water clean and sterile.

On the other hand, ozone is a colorless and irritating odorous gas with strong oxidizing power and composed of three oxygen atoms. Unlike chlorine, such ozone does not leave any harmful residues when used as an oxidizing agent.

It removes virus bacteria and has strong bleaching power.

In addition, ozone has an excellent effect of reacting with harmless organic substances such as tobacco smoke, other odorous gases, and various harmful organic substances. This ozone is over a hundred years

It has been used in various fields, such as large-scale water purification plants in Europe and the United States for a long time. Naturally, it forms an ozone layer in the global stratosphere to protect humans from strong solar ultraviolet rays.

The ozone allowable concentration of the above-mentioned ozone in a long working environment is 0.1 ppm, fresh air in the beach contains about 0.05 ppm of natural ozone, and fresh air in the forest often contains about 0.03 ppm of ozone. Ordinary people can detect the smell of ozone in the 0.01 ~ 0.03 ppm in the air.

The ozone described above has a sterilizing ability several hundred times faster than chlorine, and it is a pollution-free material having no sterilization power while retaining seven times the sterilizing power of the conventional chlorine sterilizer. The remaining ozone gas itself is gradually decomposed into oxygen.

No harm (ozone concentration half-life: 10-15 hours in air, 20-30 minutes in water).

On the other hand, ozone effects include sterilization and disinfection effect to remove various germs and viruses from indoor air, and to wash food materials such as fruits, fish and vegetables, and kitchen utensils using ozone water to remove bacteria and ticks. Remove it.

By deodorizing effect, organic gas components that cause odors in restaurants, hotels, buildings and homes are decomposed and reacted with ozone gas to create pleasant air and improve working environment by removing ozone from various factories and waste disposal facilities. .

Pesticides, harmful gases and heavy metals are removed to remove residual pesticides such as fruits and vegetables by washing with ozone water to clean them and to remove pesticides and heavy metals from groundwater.

Decomposes and cleanses with ozone and cleans various organic gases that cause pollution.

Decompose into ozone and release safely.

Long-term preservation and freshness can be extended to maintain freshness and preservation period by ozone treatment and meat ozone treatment when storing fruits and vegetables at low temperature.

Bleaching and bleaching effect is the bleaching and bleaching effect of pulp, fiber and food in the paper, textile, food industry.

On the other hand, ozone, which has sterilization and deodorization functions, has been found to be a cause of photochemical smog, and it is known to cause respiratory disorders when inhaled by the human body. The sheep should be such that they are not harmful to living things, such as humans or livestock.

Therefore, considering that the decomposition time of ozone in the natural state is about 2 to 6 hours at room temperature, in the case of an air purifier that introduces air at a constant speed by a fan, a short time for the purifying air to pass through the purifier In other words, ozone must be sufficiently decomposed within seconds.

However, in the above-described conventional apparatuses, the ozone generator and the ultraviolet lamp are disposed to face each other in the same space, so that the decomposition rate of ozone generated by the ozone generator is lowered, thereby increasing the amount of ozone contained in the purified air. Disinfection and deodorization efficiency is low

In addition, a general air purifier uses a dust collecting filter using a nonwoven fabric to remove dust contained in the air, and an activated carbon filter to remove odors and to purify air or collect ionized pollutants by an electric field. Is adopted. Such an air purifier has some effects in removing dust contained in the air, but is not known to have a great effect in reducing air pollution because it does not have a function of sterilizing bacteria contained in the air. In particular, activated carbon filters for removing odors in the air have to be replaced after long-term use, so it is not economical and troublesome replacement work has been pointed out.

The ozone lamp 15 and the ultraviolet lamp 17 can be manufactured so that desired short wavelength light or light of a plurality of wavelengths can be emitted by appropriately adjusting the type and mixing ratio of the gas injected into the glass tube.

The photocatalyst coating guide plate 29 was provided with a strong catalyst coating film 30 in close proximity to the ozone lamp 15 and the ultraviolet lamp 17.

In addition, the photocatalyst coating guide plate 29 may increase the contact efficiency with the lamps 15 and 17 while the contaminated air introduced through the air inlet 12 stays sufficiently in the ozone lamp 15 in the housing 11. The vortices are provided to the lamps 15 and 17 so as to form vortices.
