Description
Technical Field
The invention relates to a disinfection and sterilization device of a central air conditioner, in particular to a rear-mounted UV-LED deep ultraviolet disinfection and sterilization system based on the central air conditioner.
Background
In daily life, certain pathogen infectors and carriers exist in markets, supermarkets, stations or hospitals in public places, so that more viruses or pathogenic bacteria exist in a closed space, and cross infection is easily caused by the propagation of indoor air.
In the above public places, the most common sterilization means are an ultraviolet sterilization lamp (ultraviolet lamp for short) and a disinfectant, the ultraviolet lamp generates 254nm and 185nm ultraviolet rays by using low-pressure mercury vapor, the ultraviolet sterilization lamp tube directly sterilizes the applied ultraviolet rays, and the emitted light rays are ultraviolet rays which directly irradiate the human body to be greatly harmful. The volatility and toxicity of the disinfectant obviously cause harm to human bodies inevitably. Therefore, the traditional sterilization process needs to be isolated by man-machine, and the sterilization effect which works in real time and takes effect in real time cannot be achieved.
At present, it is known that ultraviolet rays have a bactericidal effect, and ultraviolet rays can destroy DNA in an organism, cause nuclear damage to pathogenic microorganisms such as bacteria and pathogens, or destroy a specific nucleic acid to cause death. It is well known that microorganisms and bacteria are feared by their ability to reproduce. If not controlled, serious disease can result. The basic principle of uv disinfection is to destroy the inside of these microorganisms, rendering their DNA non-replicable and causing fatal damage. In the process of killing various bacteria by ultraviolet rays, people and chemical substances do not need to be added. Belongs to a pure physical disinfection method and has no secondary pollution. Ultraviolet light of 254nm wavelength is readily absorbed by the organism. Ultraviolet light acts primarily on the genetic material DNA of an organism. Ultraviolet light can break and break DNA-RNA molecular bonds, resulting in the inability of bacteria to reproduce and die. Ultraviolet light with a wavelength of 185nm ionizes oxygen in the air, producing oxygen ions. The free oxygen ions are unstable and then combine with oxygen in the air to produce ozone having a strong oxidizing effect. Ozone is also effective in killing bacteria.
Based on the principle and the effect of ultraviolet sterilization, the ultraviolet sterilization lamp tube is arranged in the circulating pipeline of the current air circulating system or air purifying system, but the lamp tube is easy to damage, mercury pollution can be generated after the lamp tube is damaged, the replacement is inconvenient, the light attenuation is large, the service life is short, and the sterilization effect can be weakened. For example, there is known an ultraviolet disinfection apparatus, which is installed in a main room of a central air conditioning system and combined with the central air conditioning system to form a clean central air conditioning system with a sterilization function, the ultraviolet disinfection apparatus includes a plurality of ultraviolet lamp modules and a support thereof, the lamps adopt a modular structure, each lamp module includes a lamp holder, an ultraviolet lamp tube, a cable, etc., the ultraviolet lamp tubes on each module have the same specification, the support includes a plurality of rods, the rods are arranged in parallel or intersect to form a "#" shape, and the ultraviolet lamp modules are detachably fixed on the rods. The ultraviolet ray disinfection device of the central air-conditioning system can be widely applied to central air-conditioning systems of office buildings, meeting places, hospitals, movie theaters, hotels, trains, waiting rooms and the like and air supply systems of other pipelines, such as air supply systems of food industry, pharmaceutical factories and precision processing workshops. This ultraviolet lamp module passes through the support and arranges the cross section department at the air conditioner pipeline, and whole be "#" shape, not only can influence the efficiency of circulation of air, still gather the filth easily, need frequent dismouting and cleanness, and is very troublesome, and ultraviolet fluorescent tube itself still has aforementioned not enough, and bactericidal effect also remains to be improved.
