Description
Technical Field
The invention relates to a disinfection factor detection method and a device, in particular to a disinfection factor detection method and a device of an upper level horizontal emission sterilizer.
Background
With the continuous and deep understanding of human beings on bacterial and viruses, hospitals are also paying more and more attention to the prevention and control of viral infection, especially in the areas with infectious diseases such as tuberculosis or new coronary disease, namely, the guarantee of providing targeted disinfection equipment is needed. The existing disinfector needs to utilize a fan and the like to suck polluted air in a ward into the disinfector, and ultraviolet rays in the disinfector are utilized to kill viruses. However, the virus in the infectious ward is much, and the virus may spread when the air current in the ward, so the disinfection effect of the common disinfector is not ideal.
In order to achieve targeted disinfection, there are currently upper level flush sterilizers, as shown in particular in fig. 1; wherein, the assembly of sterilizer device 2 is on wall 1, and sterilizer device 2 can produce the ultraviolet light curtain that has the disinfection effect, and the natural convection current of disinfection room utilization air when bacterium virus 9 is located the region of ultraviolet light curtain, utilizes the ultraviolet light curtain can kill the virus, realizes high-efficient disinfection fast.
For the above-mentioned upper-layer flat-jet sterilizer, in order to achieve the effect, it is necessary to determine the sterilization effect of the sterilizer by using the performance of the high-power ultraviolet lamp tube capable of outputting the ultraviolet light curtain with the required intensity, i.e. the sterilization factor (high-power ultraviolet lamp tube). Therefore, it is very important to reflect the state of the disinfection factor in real time, so as to avoid the situation that the disinfection state is not good or even the disinfection can not be carried out.
At present, the condition of the ultraviolet lamp tube can be detected by measuring the working voltage or the working current of the ballast, or the condition of the ultraviolet lamp tube can be judged by using a feedback signal of the ballast, but the upper-layer flat-jet sterilizer is difficult to meet the measurement requirement, namely, the upper-layer flat-jet sterilizer cannot detect and judge whether the intensity of ultraviolet rays emitted by the ultraviolet lamp tube meets the requirement. When the photosensitive sensor is used for detecting the ultraviolet lamp tube, only the quality of the ultraviolet lamp tube can be monitored, and whether the intensity of the ultraviolet lamp tube meets the requirement cannot be detected.
When the ultraviolet intensity sensor is used for detecting the condition of the ultraviolet lamp tube, the ultraviolet intensity sensor needs to be extremely close to the ultraviolet lamp tube, and for the upper-layer flat jet type sterilizer, because the ultraviolet intensity emitted by the high-power ultraviolet lamp tube is high, when the ultraviolet intensity sensor is close to the high-power ultraviolet lamp tube, the measuring range of the existing ultraviolet intensity sensor generally cannot meet the measuring requirement, and under the high-intensity irradiation intensity, the service life of the ultraviolet intensity sensor and the service life of a corresponding circuit cannot meet the requirement of long-term use.
