Description
Technical field
This utility model relate to a kind of to room air carry out disinfection, sterilization and deodorant device, particularly a kind of irradiation under ultraviolet ray and filter screen of utilizing carries out air sterillization, sterilization and deodorant device.
Background technology
Along with the requirement of people to high-quality life, and owing to global population constantly increases, comsumption of natural resources amount constantly increases, cause natural environment and environmental destruction, many new infectious disease constantly attack the mankind, and a lot of in addition construction materials and finishing material volatile matter cause people's living environment is polluted.These factors form serious threat to environment for human survival, therefore, improve our environmental health situation, reduce the influence of environmental pollution to health of people, are the problems that present people show great attention to.
Investigation shows that the major pollutants in the air-conditioning have four kinds: the one, and biological pollution comprises antibacterial, mycete, pollen, algae, plant, insecticide, protozoacide, virus etc., can cause allergy, acariasis; The 2nd, chemical contamination comprises volatile organic matter, carbon monoxide, ozone etc.; The 3rd, physical contamination comprises extraneous dust coal ash, flue dust, heavy metal, concrete grey, greasy dirt, inorfil, lubricating oil and oil etc.; The 4th, other microorganism.The water tank of air conditioning system is the main breeding spot of legionella especially.Can spread all over the bed rearrangement building through pipeline, along with flowing of air, dirt in these pipelines propagates into various antibacterials, mycete, fungus, virus and biological pollutant indoor, and infringement is active people in the air conditioning chamber for a long time, and the time has been grown and just caused so-called " sick building syndrome " easily.I.e. " sick building syndrome " or other relevant diseases.EPA was done similarly investigation, proved that the pollution from air conditioner ventilation accounts for the over half of room air gross contamination degree.
In the past in decades, the scientific research personnel has made unremitting effort for solving air sterillization and air cleaning problem, has developed multiple air to be purified and the disinfectant device, and more widely used have ozonization equipment and a ultraviolet circulated air sterilizing equipment decontaminating apparatus.
For example, notification number is to disclose a kind of " ultrathin room air sterilizer " in the utility model patent of CN2209529Y, this device produces ozone by increase anion generator in existing air cleaner, ozone is delivered to wind channel by blower fan and discharge, thereby reach the effect of removing foreign flavor indoors and sterilization from air outlet.
In addition, notification number is to disclose a kind of " dedusting and purifying air disinfector " in the utility model patent of CN2549370Y, is applicable to the ventilation shaft inside that is arranged on central air conditioner system.Its primary structure is that the side near air inlet is installed electrostatic precipitator in housing, the outlet of electrostatic precipitator is connected with ozonator, end near air outlet in housing is provided with the ozone decomposer, in housing, the position that is positioned at air inlet is provided with centrifugal blower, and the outlet of centrifugal blower utilizes guide duct to be connected with electrostatic precipitator.This device can utilize electrostatic precipitation, utilizes the ozone with high concentration generation technique that air is carried out the taste removal sterilization processing, and air is purified.
Above-mentioned equipment adopts ozone generating-device to discharge ozone, ozone is a kind of strong oxidizer, carry out very rapid reacted in deactivation to antibacterial, by reacting with the two keys of bacteria cell wall lipid, penetrate thalline inside, act on albumen and lipopolysaccharide, change the permeability of cell, thereby cause antibacterial death, its shortcoming is: a little less than the penetration power of ozone, low to object vertical-depth killing bacteria ability; And the demonstration of scientist's current research, ozone has negative effect to the cholesterol in the human blood, and it can promote arteriosclerotic formation, and then causes cardiopathic burst.
In addition, publication number is to disclose a kind of " air sterillization sterilization purification device " in the utility model patent of CN264231Y, is provided with the high-pressure mercury Burdick lamp in this device, and inwall scribbles photocatalyst of titanium dioxide, also is provided with drainage screen and anion generator.The intravital air of access to plant shell, at first it is shone by the high-pressure mercury Burdick lamp, bacterial micro-organism is killed, making air ionization produce ozone by ultraviolet simultaneously sterilizes, air fully contacts with the photocatalyst of titanium dioxide that is coated in inner walls under the irradiation of high-pressure mercury Burdick lamp, and Organic substance and photocatalyst carry out decomposition reaction, so that the elimination harmful gas, and reach deodorization, taste removal and sterilization effects; Subsequently, through drainage screen filtration and interpolation anion air is further purified again.
By ultraviolet to the technology of air sterillization be utilize the ultraviolet of suitable wavelength in can the destroy microorganisms body cell DNA (DNA (deoxyribonucleic acid)) or the molecular structure of RNA (ribonucleic acid), cause the growth cell death and (or) the reproducibility cell death, reach the effect of sterilizing.Its shortcoming is: ultraviolet only shines body surface and reaches certain exposure rate standard just bactericidal effect, and it is invalid substantially to surpass in 1.5 meters scopes in addition of ultraviolet light source; The ultraviolet radiation sterilization needs long action time, generally will shine more than 6 hours; And ultraviolet can not be removed airborne chemical pollutant such as formaldehyde etc.
