Description

Combined air purifying and sterilizing device
Technical Field
The invention relates to an air purification device, in particular to a combined air purification and sterilization device. The method is used in the technical field of household appliances.
Background
The health and life safety of people are directly affected by urban building syndrome, indoor air conditioning diseases, organic pollution and the like caused by modern living environment, indoor decoration and the like. Because the central air conditioning system cannot be cleaned and disinfected frequently, the interior of the system becomes a breeding place for bacteria, so that the environmental pollution is increasingly paid attention to. Particularly, the problem of cross infection of infectious diseases due to the use of a central air conditioning system is receiving attention. The existing air purifier mainly adopts an activated carbon adsorption technology, an ozone purification technology, an anion dust removal technology and a high-voltage static technology. The active carbon adsorption technology can only adsorb and store harmful substances, but can not decompose or remove the harmful substances, and only transfers pollution sources. Ozone technology has the effects of sterilization and deodorization, but has low removal efficiency on organic pollutants, and ozone is harmful to human bodies and the environment. The anion and high-voltage electrostatic technology is a physical action process, can remove smoke dust in air, but cannot remove and purify pollution caused by chemistry, biology, microorganisms and the like.
Photocatalysis is an emerging environmental purification technology. Nano TiO 22The photocatalyst can effectively oxidize or reduce harmful gas molecules adsorbed on the surface of the photocatalyst, kill bacteria, inhibit viruses, convert harmful organic matters, bacteria and the like into harmless substances such as water, carbon dioxide and the like, and has no secondary pollution. Therefore, in recent years, it has become a research focus for indoor air purification.
Found by literature search, the patent names of the invention are as follows: indoor air purification method and device, and patent applicationThe number is: 03126563.4, which discloses an activated carbon filter, ultraviolet lamp and nano TiO2The air purification means of photocatalysis combination. However, because the gas flow of the central air conditioner is large, the primary air purification rate of the photocatalysis is often low, and although the concentration of pollutants in the air can reach the indoor air quality standard through multiple cycles, the problem of infectious disease cross infection caused by the use of the central air conditioning system cannot be effectively solved. Meanwhile, the active carbon can only adsorb but not remove harmful gases, which finally causes secondary pollution. On the other hand, the ultraviolet light source used by photocatalysis can generate ozone, although the ozone has the sterilization and disinfection function, and can generate coupling effect with photocatalysis, thereby obviously improving the activity of photocatalysis. But if not properly controlled, the environment is often polluted, andcausing harm to human health.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a combined air purification and sterilization device with the functions of efficiently removing organic pollutants in indoor air and sterilizing, after particles and dust are collected through a primary filter screen and high-voltage static electricity, the combined air purification and sterilization device can efficiently degrade the organic pollutants and sterilize under the ozone-nano photocatalysis coupling action, and the excessive ozone and the residual organic pollutants are absorbed through water mist, so that the pollutant removal rate can be high through one-time passing. Multiple treatments are carried out, and the method is safe and reliable.
The invention is realized by the following technical scheme, and the invention comprises the following steps: particle trapping assembly, ozone-photocatalysis assembly, water mist spraying-gas-water separation assembly. The connection relationship is as follows: according to the airflow direction, the particle trapping assembly is arranged at the forefront, the ozone-photocatalysis assembly is arranged behind the particle trapping assembly, the water mist spraying-gas-water separation assembly is arranged behind the ozone-photocatalysis assembly, the three assemblies are independent and parallel to each other, the periphery of the three assemblies is tightly connected with the air pipe, and all the airflows sequentially pass through the particle trapping assembly, the ozone-photocatalysis assembly and the water mist spraying-gas-water separation assembly.
The particle trapping assembly consists of a primary filter screen and a high-voltage electrostatic dust removal component. The two parts are parallel to each other, the parallel surface is perpendicular to the airflow direction, and the size of the parallel surface is consistent with the inner section of the pipeline.
The ozone-photocatalysis component comprises a nanometer photocatalysis reaction sheet and an ultraviolet lamp light source. The nano photocatalytic reaction sheet can be a foam metal loaded nano photocatalytic net or a filter screen made of composite nano photocatalytic particles, and the filter screen is preferably in a wavy shape in order to reduce the flow velocity of air flow vertically passing through the net. The ultraviolet lamp light source is a cold cathode ultraviolet lamp tube or a common ultraviolet lamp tube which can generate certain ozone. The filter screen made of the composite nano photocatalytic particles is more than two layers, and the layers are parallel to each other and are vertical to the direction of air flow; the ultraviolet lamp tube is positioned between every two layers of the filter screen made of the composite nanometer photocatalytic particles and is parallel to the filter screen.
The water mist spraying-gas-water separating component is internally provided with a nozzle, a water mist intercepting net, a bent gas-water separator, a water storage tank, a regulating valve, a water pump or an air pump and a connecting pipeline. A water storage tank is positioned at the bottoms of the water spray interception net and the elbow-shaped gas-water separator; the water storage tank, the regulating valve, the water pump (or the air pump) and the nozzle are connected by connecting pipelines.
After air enters the system, micro particles are removed by the primary filter screen and the high-voltage electrostatic dust removal component and then enter the ozone-photocatalysis component. Under the oxidation action of ozone, the photocatalytic degradation action, the ultraviolet lamp irradiation and the synergistic action of the ozone, the photocatalytic degradation action, the ultraviolet lamp irradiation and the ultraviolet lamp irradiation, organic pollutants, bacteria and the like in the air are oxidized, decomposed and killed. Residual ozone gas and organic pollutants are absorbed under the action of a large amount of micro water mist, meanwhile, the water mist is intercepted by a water mist intercepting net and a crank-shaped gas-water separator, and finally, clean air is discharged.
The present invention selects an Ultraviolet (UV) lamp tube capable of generating ozone as a light source for photocatalysis. This has two roles: first, interaction of ozone with UV, second, photocatalysis (e.g. TiO)2) Interaction with ozone. Through the synergistic effect, a large amount of OH with high oxidizing capability is generated, so that the organic matter is effectively removedContaminants and kill bacteria. Can be briefly expressed by the following chemical reaction equation:

(9)
in the formula (9), M represents an organic substance in the air. TiO 22Under the irradiation of ultraviolet light, an electron-hole pair is formed, and ozone has strong electrophilicity, so that the recombination probability of electrons and holes is degraded, and the purpose of degrading organic matters is achieved. In addition, after the ozone captures electrons, the electrons are combined with hydrogen ions to generate high-activity hydroxyl radicals, so that organic matters in the air are better degraded.
The invention also utilizes water mist to spray and form mist water particles with different sizes from tens of microns to hundreds of microns, thereby greatly improving the contact area between water and gas and leading residual ozone, organic gas and the like to be quickly absorbed by the water particles; the water mist is intercepted by the water mist intercepting net and the crank-shaped gas-water separator and is separated from the gas. The crank-shaped gas-water separator consists of crank-shaped blades, the distance is 10mm-100mm, the length and the number of corners can be 2-8, and the crank-shaped gas-water separator is determined according to the conditions of airflow resistance and separation effect. The solubility of ozone in water is tens of times of that of air, and simultaneously, the ozone and the captured organic gas in the water solution continue to generate oxidation-reduction reaction to obtain further purification. The water for spraying the water mist is recycled and added or replaced periodically.
Compared with the prior art, the invention utilizes the particle trapping component, the ozone-photocatalysis component and the water mist spraying-gas-water separation component, can not only utilize ozone to assist to achieve the purposes of efficiently removing pollutants in gas and killing bacteria, but also eliminate the pollution to the environment caused by the residual of ozone, thereby achieving the purposes of efficiently removing the organic pollutants in the gas and killing the bacteria. The technology of the invention is particularly suitable for indoor air purification of the central air-conditioning system, and can effectively solve the cross infection of infectious diseases caused by the use of the central air-conditioning system; it can also be used for indoor air humidifying and purifying device.
