Description
Technical field:
The present invention relates to the air purifying and sterilizing sterilization, specifically be meant the purification sterilization of circulating air in the central air-conditioning ventilating system, i.e. the application of clean technology.
Background technology:
Widely used central air-conditioning mainly is divided into water-cooled and air-cooled two kinds in the modern architecture, and the design principle of its ventilating system is consistent with general structure.The wind cyclic process is: new wind is sucked by fresh wind port, enter air shaft, again by the low efficient filter in the Ventilator Room, air after the filtration is through fan coil, in the central air-conditioning unit, be compressed into needed cold and hot wind, and through humidification after ajutage is sensible indoor from air outlet, an indoor wind part is discharged building through exhaust outlet, another part comes back to fan house by backwind tube, participates in circulation next time.
Existing central air-conditioning only has clear and definite requirement to airborne dust containing capacity, humidity, maximum supply air temperature difference and minimum rate of ventilation, and the purification techniques major measure is that the low efficient filter and the humidifier of filter particulate material, no disinfectant measure are installed.Therefore, by the wind that new wind and room air are formed, virus wherein and bacterium can't effectively be killed by existing apparatus, may cause the cross-infection of various pandemics in the crowd.
Present central air-conditioning air disinfection method mainly contains and installs ozone generator additional, sprays all kinds of thimerosals, its weak point is that the purification sterilization of ozone effectively, is difficult to the changeable architectural environment of adaptation situation in fixed-area, and peculiar smell is arranged, the excessive body health of speaking sarcastically that has.Various thimerosals all impair health.
Nonwoven is widely used in making high efficiency particulate air filter, and intensive irregular fiber and electrostatic effect can play control of dust, dedusting effect to aerial all kinds of impurity, efficiently reaches 99%.
The self-replacation cycle of microorganism can directly be killed or disturb to the sterilization enzyme, can directly kill all kinds of germs more than 90%.
The C-band ultraviolet lamp of wavelength 240-280 nanometer has very strong bactericidal potency, can make microbial death or forfeiture fertilities such as most of cell, virus, in seconds just can reach desirable sterilization effect.
Existing photocatalyst is done catalytic reaction with light source, and photosemiconductor material and organic pollution chemical combination, and organic pollution resolved into free of contamination water and carbon dioxide also have functions such as deodorizing, antifouling, hydrophilic, antiultraviolet in addition.
Summary of the invention:
The objective of the invention is to, coronavirus killed refining sterilizer of central air-conditioner ventilation system is provided, this device is installed the high-efficiency antimicrobial filter by the Ventilator Room front end in the central air-conditioning ventilating system, the C-band ultraviolet lamp is installed in backwind tube and is sprayed photocatalyst at air outlet, can strengthen control of dust, the dedusting dynamics, and kill various coronavirus and other virus and the bacterium that comprises SARS effectively, make virus and bacterial number in the room air reduce greatly, it is media cross-infection in the crowd that various pandemics are difficult to the central air-conditioning.
In order to achieve the above object, the present invention adopts following technical scheme: coronavirus killed refining sterilizer of central air-conditioner ventilation system, this device comprises: fresh wind port, air shaft, high-efficiency antimicrobial filter, Ventilator Room, fan coil, ajutage, air outlet, backwind tube, C-band ultraviolet lamp, photocatalyst of titanium dioxide.
The air shaft of coronavirus killed refining sterilizer of central air-conditioner ventilation system is connected with fresh wind port, the high-efficiency antimicrobial filter is installed in air shaft and Ventilator Room junction, fan coil is connected with Ventilator Room, ajutage is connected with fan coil, the port of ajutage is an air outlet, spray photocatalyst of titanium dioxide in air outlet, backwind tube is connected with Ventilator Room, and the ultraviolet lamp of C-band is installed in the backwind tube.
The high-efficiency antimicrobial filter is made up of nonwoven filtrate, sterilization enzyme, flange and bracing frame.Spraying sterilization enzyme is made pouch with the nonwoven filtrate on the nonwoven filtrate, is installed in flange and the bracing frame.Average per 10 meter amperes dress 20-40 props up 30-70 watt C-band quartz burner in backwind tube.
The workflow of coronavirus killed refining sterilizer of central air-conditioner ventilation system of the present invention is: new wind sucks from fresh wind port, pass through air shaft, through the high-efficiency antimicrobial filter, enter Ventilator Room, in fan coil, be compressed into needed cold wind or hot blast then by the central air-conditioning unit, humidification is after ajutage is sensible indoor from the air outlet that has sprayed photocatalyst of titanium dioxide again, the backwind tube of room air through the C-band ultraviolet lamp has been installed participates in following also to fan house next time.
The present invention compared with prior art has following advantage: do not change existing central air-conditioning overall structure, usage charges are low; The high-efficiency antimicrobial filter that adopts the nonwoven filtrate to make can filter the dust of particle diameter more than 0.3 micron effectively, and the mistake wind resistance is low, filter efficiency reaches 99%, than the high 30%-40% of existing filter efficiency; Sprayed the sterilization enzyme on the nonwoven filtrate, the ultraviolet germicidal lamp of C-band has been installed in backwind tube and has been sprayed photocatalyst of titanium dioxide at air outlet, therefore, can kill microorganisms such as the airborne various bacteriums of ventilating system, acarid, mould, virus and unit cell algae effectively, fast, and non-secondary pollution.
