Abstract

The utility model relates to antibiotic filter gauze of air conditioner, in particular to a filter gauze which can kill and inhibit bacteria and virus adsorbed on the filter gauze at the same time of filtering air. The antibiotic filter gauze adopts active carbon fibers which are loaded with at least one of silver, copper, or zinc ions as a filter layer, the two sides of which are loosely fixed with silk screens with pore diameters larger than 0.5 mm and the margin is fixed with frames. The new gauze can effectively filter suspended substances in the air and absorb harmful gases as well as kill bacteria and virus. The utility model has a simple structure and is suitable for various conditioner filter systems.

Description

A kind of antibiotic air-conditioning filter net

Technical field

The utility model relates to a kind of antibiotic air-conditioning filter net, especially in filtered air, can kill and suppresses to be adsorbed on the bacterium on the screen pack, the air-conditioning filter net of virus.

Background technology

The air-conditioning system of operation adopts most of room air to circulate, to reach energy-saving effect more at present.Adopt the public arena of air-conditioning system,, can cause increasing in the air quantity, the especially issuable Legionella of central air-conditioning cooling system of suspended particulate substance, bacterium, virus, will people's health be constituted a threat to because air can not upgrade in time.If the fresh air proportion of displacement is too big, will cause energy consumption to rise significantly.

At present the sterilization measure of air-conditioning system is mainly contained physical sterilization, the chemical bactericide sterilization of ultra violet lamp.But air can produce ozone under ultraviolet irradiation, though ozone has certain bactericidal action, its excessive concentration can cause headache, symptom such as uncomfortable in chest, dizzy; The corrosion that the chemical bactericide sterilization often brings air-conditioning system, and frequent sterilization could be in order to be effective.

Patent 00127594 is released the manufacture method of a kind of broad-spectrum antibacterial and anti-mildew air-conditioning filter net and used antibacterial antimildew polyacrylic fibres thereof, by the chemical reaction nano level silver of absorption and silver oxide particle in the surface of silicate clay and micropore, method by spinning is spun into the polyacrylic fibres that has nanometer-level silver on the surface then, forms the air-conditioning filter net with antibacterial and mouldproof effect by weaving again.But can not guarantee that a large amount of Nano Silvers and silver oxide in spinning process, are covered by macromolecule, thereby make greatly discount of antibiotic, fungistatic effect, and polypropylene fibre pernicious gas in the absorbed air well, detergent power is lower.

Summary of the invention

In order to overcome sterilization of air-conditioning system medium ultraviolet and the existing defective of chemical sterilization, solve the sterilizing efficiency and the low problem of detergent power of present air-conditioning filter net, the utility model is released a kind of antibiotic filter screen, suspension in the filtered air effectively, and pernicious gas and the kill bacteria in the absorbed air effectively.

The technical scheme that its technical problem that solves the utility model adopts is: adopt and cover Ag-bearing, copper, a kind of active carbon fiber felt or activated carbon fiber cloth of zinc ion at least, filtering layer as antibiotic filter screen, the two sides is easily fixing keeping air permeability and good greater than 0.5mm woven wire or plastic silk screen with the aperture, and the edge can adopt metal framework or wooden, plastic frame to fix.

In order to save cost, can will cover Ag-bearing, copper, a kind of active carbon fiber felt or activated carbon fiber cloth of zinc ion at least, being superimposed with common carbon fibers felt that does not cover year silver, copper, zinc ion or activated carbon fiber cloth forms the filtering layer of antibiotic filter screen.Wherein silver ion can also be used nanometer metallic silver and corresponding oxide Ag/Ag ₂The O compound provides.

Activated carbon fiber has very high specific area and absorption property, effectively suspension in the filtered air and pernicious gas.According to adsorption mechanism, adsorption and desorption is a reversible process.Promptly in adsorption process, there is the phenomenon of desorb to exist; When absorption had just begun, based on adsorption reaction, its inverse process was separated suction phenomenon and can be ignored; But after reaching certain adsorbance, the speed of desorb is just apparent in view; When adsorption and desorption speed equates, reach adsorption equilibrium.From the statistics angle, ion or suspended particulate from be adsorbed the material sorption to coming off fully from sorbing material, have the regular hour yardstick; The bacterium of required filtration, virus, the possible survival ability that has is stronger, can survive for a long time under the normal temperature, is far longer than the mean residence time on adsorbent.Therefore, filter bacterium, virus and the suspended particulate substance of high concentration by activated carbon fiber merely, can produce the desorb of bacterium, virus inevitably, reenter air and water body and form infection.But cover the silver, copper, the zinc ion that are loaded in the activated carbon fiber surface, can in bacterium, viral sorption in the time period on activated carbon fiber surface, chemical action take place to kill it.

The beneficial effects of the utility model are, the suspension in the filtered air effectively, and pernicious gas and kill bacteria and the virus in the absorbed air effectively are simple in structure, applicable to multi-form air-conditioner filtering system.
