(1) Brief Introduction
Thus it can be seen from the pollution avenues that people us are an important source of pollution. Article is one of the main media which affects air purifying (80% of the dust come from human beings). So we should adopt strict and scientific management policy to control the pollution
In order to ensure the disinfecting efficiency and great efficiency after long-term? usage, the practical use of dynamic disinfecting must adopt multi-technique and reasonable settings. Only coordinate well can achieve a perfect result because single function of disinfecting has a weakness
(2). operating principles
■ High-strength ultraviolet sterilizing
As early as 1942, scientists found that the lethal dose for ultraviolet to some microorganism is:
Staphylococcus aureus: 2180-4950uw.s/cm2
Typhoid bacillus: 2140uw.s/cm2
Bacterium coli: 2100-6400 uw.s/cm2
Bacterium aeruginosum: 6500uw.s/cm2
From 1987 to 1990, some home and abroad scientists proved that the average ultraviolet strength of 9400uw/cm2 could kill the germs in flowing air in 0.0625 to1 second. So we erect high-strength and long service life ultraviolet tube without ozone and the equipment which could improve the ultraviolet radiant intensity in the machine. So the built-in radiant intensity comes over 11000-15000uw/cm2.
The government prescribed that the ozone concentration must be less than 0.16mg/m3 in the place with creatures. So our products have been tested by SCCDC and the ozone density is less than 0.06mg/m3 in the process of working which is identical with the concentration of air.
■ Filtering, dusting and degerming
Air filtering is the most effective, safety, practical and convenient means of disinfecting. So adopting suitable filter will ensure blowing ?n airstreams attaining the required density of dust and germs. (Equal to the three-level filtering of 1st class environment requirement of china. The notebook of America for the engineers institute on heating, refrigeration and air conditioner and of 1998 pointed out)
■ Oxygen anion generator
Oxygen anion is the air microorganism for the living room of human beings. People are energetic and feel well physically in the environment with high content of oxygen anion. So our company developed high-efficiency oxygen anion generator. It can disinfect as well as produce a crisp air environment for the medical professionals.
■ Activated carbon filtering film
Activated carbon is the best remover of smog, peculiar smell, carbon monoxide, ammonia and some harmful gas. It has the features of good filtering efficiency, duplication of using and long service life.
■ High-tension electrostatic absorption
It adopts high-tension electric ion adsorbing principle to remove dust and germs. But it is difficult to attain the multi-target for the purifier. It couldn? be used as terminal purifying setup in clean operating room and also it could not be set up directly in clean room because it has lower and unstable efficiency of dusting as well as produce secondary dust. Therefore, we used it as auxiliary facility.

（6）Advanced Technology
■ Failure automatic detection alarm prompt of filtering system, etc.
Long-term and repeat use of filtering system will result in filter gauze blinding that affects the sterilization greatly. Such blinding will decrease the indoor air circulation frequency and repeat cleaning will cause that it no longer possesses the function of filtering, degerming, dusting and refreshing air, etc. However, it is impossible to check the filtering system daily in service use and thus automatic detection function could lighten the working load, strengthen the management and make the sterilizer normally operating at all hours.
■ High-strength ultraviolet intensity detecting
Only the built-in ultraviolet strength attains over 600 uw/m2, can it achieve greatest disinfecting effect. So you can examine the ultraviolet strength in the machine at any time, It is not only no need to use ?ltra-violet strength detector?to check it one by one but also it will do no harm to the operators who detect the built-in ultraviolet strength. It is the management to the emollient guarantee of the work environment and science
■ Standby ultraviolet tube automatic staring device
Meeting trouble of the ultraviolet tube, there? no need to replace the ultraviolet tube immediately because the standby ultraviolet tube will operate automatically which ensures the normal operation of the machine.
■ Infrared microwave automatic detection of environment pollution
The sterilizer detects working environment automatically at any time.. Once if finds a human body, the sterilizer will go into operation automatically and then will stop work automatically after the people have left for ten minutes. (if any body entered the sterilized room, it will cause secondary pollution). Therefore, to control the microorganism in air is mainly to reduce the pollution brought by people and in this way it could keep the indoor air reaching the stable sterilization effect and finally achieve the real dynamic sterilization.
