The air sterilization/disinfection device in the utility model can efficiently kill above 99.5% bacteria and viruses in the vent air, has the advantages of simple structure, low cost, less energy consumption, and easy arrangement and maintenance, and is widely used in the air supply, air return or exhaust pipelines of ventilation air-conditioning systems in buildings, transport facilities or other closed spaces.
Description
Technical field the utility model relates to a kind of air sterillization sterilizing unit that is applicable to the heating ventilation and air-conditioning system, particularly uses ultraviolet ray and microwave sterilization to kill the device of airborne microorganism in ventilation, the air-conditioning system.
The background technology air cleaning processing method in ventilation and air conditioning system and device at present mainly contains following several:
Filtration method promptly is provided with filter on the circulation of air section, the airborne solid particulate matter of filtering reduces the dust content in the vent air, also can reduce in the air with bacterium and the viral level of dust as the host simultaneously.This method is widely used, but it is low to nominal particle size dust purification efficient, and bacterium and virus that the solid particulate matter that is filtered out carries can not be killed, and still has the danger of leaking diffusion once more.So simple air cleaner can't the thorough disinfection sterilization.Particularly with air during as the disease transmission of communication media, ventilation and air conditioning system may become the passage of cross-infection.
Absorption method adopts airborne small dust of adsorbents adsorb and bacterial viruses such as active carbon, is a kind of effective method, but because adsorbent needs frequent the replacing or regeneration, and it is less to handle air mass flow, so be not suitable for the large-scale centralized ventilation and air conditioning system.
Ultraviolet sterilization, as Chinese patent " high-intensity ultraviolet duct type air disinfector " (application number 01226496), " having the electric air feeder and the air conditioner unit that strengthen anti-microbe ability " (application number 02108091) and " the ultraviolet air disinfector of air-conditioning unit " (application number 00258277) etc., the high intensity ultraviolet lamp is set in air system plumbing, the air that passes through is carried out ultraviolet radiation disinfection, but because ultraviolet ray irradiation air sterillization sterilization needs the long time (more than 10-30 minute), and in the air channel air velocity generally more than 3m/s, be that the time of staying of air in this sterilizer is less than 5 seconds, so can't play sending/sterilization of return air air at all.
Ultraviolet ray combines with photocatalyst, as Chinese patent " air cleaning facility " (application number 02202864), mainly by being decomposed airborne organic pollutant by the photocatalyst of ultraviolet ray irradiation, consider the solid particulate matter that removes during photocatalyst air cleaner filtered air and will cover photocatalyst surface, isolated ultraviolet ray is to the direct irradiation of photocatalyst, this kind sterilizing method and device lose the function of decomposing organic pollutant, so can not satisfy the needs of large-scale centralized air-conditioning and ventilating system.
The sterilizing and purifying method of cooperation of cold plasma special air purifying layer, as Chinese patent " the sterilizing and purifying method and apparatus of cooperation of cold plasma special air purifying layer " (application number 01107933), adopt a kind of cooperation of cold plasma catalyst T21, catalyst T260, special air purifying layer sterilizing and purifying method to air, the device more complicated that this kind method adopts, the air mass flow that can handle is little, only is applicable to the air sterillization sterilization of middle-size and small-size special-purpose ventilation and air conditioning system.
Ozonization as Chinese patent " electronics electric air sterilization clarifier " (application number 92233706) and " air circulation sterilizer " (application number 92215266), adopts ozone that ozone generator produces to the air sterilization that carries out disinfection.Because ozone gas is harmful, so after ozone generator the ozone reduction device must be set.But ozonization needs long-time sealing to handle, and air contacts with ozone in the process of flowing through between ozone generator and the ozone reduction device and that time of oxidation reaction takes place is very short, and sterilization effect is very poor.So be not suitable for ventilation and air conditioning system air sterillization sterilization.
In addition sterilizing method and device also have chemical fumigation, high-temperature sterilization, microwave, ultrasonic wave etc., and for various reasons, the application in ventilation and air conditioning system does not also obtain promotion and application.
Summary of the invention is in order to overcome above-mentioned the deficiencies in the prior art, and it is a kind of more effective and easy that the utility model will provide, and is applicable in ventilation, the air-conditioning system the carry out disinfection device of sterilization of air.
Air disinfecting device in the said ventilation of the utility model, the air-conditioning system, it comprises: the metallic conduit shell with air inlet and air outlet, close air inlet end in this shell, cross section along conduit enclosure is provided with air cleaner, is provided with ultraviolet lamp group in the one or both sides of this air cleaner; And in this conduit enclosure, be provided with the microwave radiation area near air opening end, this microwave radiation area is by section of tubing shell and two spaces that the metallic microwave reflector net of settling along cross-section of pipeline constitutes, at least one microwave emitter is installed on the metallic conduit shell in this microwave radiation area, and microwave emitter is placed on the miniature electric driving shaft, settle the microwave energy receiver on the opposite side conduit enclosure relative with microwave emitter, the signal that receives is given automaton by sensor feedback, the transmitting power of control microwave emitter.
For the more effective bacterium and the virus of adhering on the micronic dust that is filtered the device filtering of killing, high-intensity ultraviolet lamp group is installed in an air cleaner side down with the wind, in one week of the same cross section of conduit enclosure upper edge shell one group of ultraviolet lamp is installed, and add reflection shield, guarantee that light that each ultraviolet lamp sends can both the whole filter of direct irradiation plane; In the other side of air cleaner, same one group of ultraviolet lamp group also can be installed, continue to kill and Lou consider microorganism (bacterium, virus) in the past.
In order to improve the efficient of air cleaner, can on air cleaner, add static, to improve absorption affinity, to reduce to leak and consider micronic dust.
Because always having more small grit to leak, any air cleaner considers in the past, be attached to and leaked the bacterial virus of considering on the past grit, because of the ultraviolet irradiation time deficiency, might do not killed fully, but just be difficult to escape the misfortune thoroughly killed when they enter the microwave radiation area.
Air sterillization sterilizing unit of the present utility model divides two and kills the interval, kills means with two kinds, on the structure of device, can be divided into two bodies, can be overall use, also can partial installation, even monomer independently uses.
Air cleaner needs often to clean, and ultraviolet lamp group and microwave emitter etc. also needs cleaning, maintenance or changes.In order to overhaul with easy for installation, offer access door on the conduit enclosure in ultraviolet radiation zone and microwave radiation area, this door should be able to be closed locking and sealing, and can the shield microwaves radiation.
Air sterillization sterilizing unit of the present utility model reaches more than 99.5% through preliminary test its microorganism (bacterium and virus) killing rate.It is specially adapted to the air continuous sterilization sterilization of air-supply in the heating ventilation and air-conditioning system of building, car and boat and other enclosure spaces, return air and air draft.This apparatus structure is simple, with low cost, energy consumption is little, and (repacking) convenient maintenance is installed.
