Description

Operation maintenance system of antibacterial and degerming air purifier
Technical Field
The invention relates to the field of air sterilization and purification and software and hardware, in particular to a software and hardware system for monitoring ultraviolet irradiation intensity in an antibacterial and degerming air purifier, controlling the opening and closing of an ultraviolet lamp, recording the running time of the ultraviolet lamp in the air purifier and the installation and cleaning or replacement date of each part needing cleaning or replacement, and reminding an owner of timely cleaning or replacement of each part.
Background
Ultraviolet radiation (UV-C) is a validated sterilization method that can be used to inactivate bacteria, viruses and microorganisms in water, air and solid surfaces, including novel coronaviruses and common influenza viruses. The ultraviolet sterilizing lamp is arranged in the air pipe of the central air conditioner, so that the damage possibly caused by direct irradiation of ultraviolet rays to a human body is avoided, the long-acting sterilizing device is also capable of sterilizing for a plurality of times through air circulation, and the problem of eliminating the killing angle of the traditional ultraviolet lamp caused by blocking light is solved.
The uv dose plays a critical role in the sterilization process. The uv dose may be expressed as the product of uv intensity and irradiation time. In the condition of sufficient ultraviolet dose, the inactivated virus and bacteria cannot be revived, but in the condition of insufficient ultraviolet dose, many virus and bacteria inactivated by ultraviolet irradiation can repair the damaged structure by the assistance of light. When the ultraviolet dose is the same, the irradiation mode with high intensity, short time or low intensity and long time can be adopted to achieve the aim of sterilization. A recent study was published by Milan university, IRCCS Foundation and Italian national physical institute of celestial bodies: the UV-C ultraviolet light can effectively inhibit novel coronaviruses. Researchers used different power UV-C ultraviolet light source to irradiate the new coronavirus, respectively at 3.7mJ/cm2,16.9mJ/cm 2 and 84.4mJ/cm 2 ultraviolet radiation dose through real-time Polymerase Chain Reaction (PCR) detection of new coronavirus pathological effects. Experimental results indicate that UV-C radiation can inhibit viruses, and that the response depends on the UV-C dose and virus concentration. For typical low virus concentrations, a UV-C dose of less than 4mJ/cm2 is sufficient to achieve complete inactivation of the virus, even at maximum virus input concentration moi=1000, with UV radiation doses up to 16.9mJ/cm2 being able to completely inhibit coronavirus.
According to the paper "polyvinylpyrrolidone iodine, physical method and chemical disinfection for inactivating SARS virus" completed by Hiroaki Kariwa, nobuhiro Fujii and IKuoTakashima, (Inactivationof SARS coronavirus by means of povidone-iodine, physical conditions and chemical reagents") is described in the paper, after the SARS virus in the culture medium is irradiated with ultraviolet light with the intensity of 134. Mu.W/cm 2 for 15min, the inactivating rate of the SARS virus is tested to be above 99.9995%, and the tailing phenomenon fed back from the experimental curve shows that the culture medium can protect the SARS virus. Whereas the curve from the beginning to 5 minutes of irradiation shows that SARS virus is more than 99.9% inactivated at 5 minutes of irradiation. The UV dose required for 90% inactivation was converted to about 13mJ/cm 2.
According to the national standard of ultraviolet germicidal lamp (GB 19258-2012), even if the lamp does not extinguish, the attenuation of the ultraviolet intensity reaches 50%, namely the lamp is regarded as reaching the average service life, and the average service life must be more than 5000 hours. The effective life of ultraviolet lamps is the cumulative ignition time when the ultraviolet intensity value is reduced to 70% of that prescribed by the present standard, as prescribed by the national standard "ultraviolet sterilizer health requirements" (GB 28235-2020). Many traditional air conditioner ultraviolet sterilization devices do not have an ultraviolet intensity detection device, and whether the ultraviolet dose meets the sterilization requirement cannot be determined, and the ultraviolet lamp loses 30% -50% of intensity along with the aging of the ultraviolet lamp, so that the ultraviolet lamp cannot be guaranteed to have long-term reliable ultraviolet sterilization capability. Under different wind speed conditions, the requirements on the ultraviolet dose are different, the higher the wind speed is, the larger the pipeline size is, the larger the ultraviolet dose is required, and under the high wind speed condition, if the ultraviolet dose cannot be improved, reliable sterilization cannot be performed; if the ultraviolet dose is too high under the condition of low wind speed, the service life of the ultraviolet lamp is wasted. The amount of uv light required to kill different bacteria, viruses and microorganisms also varies widely at different risk levels. Because the air conditioner air pipe is usually arranged at a hidden place or a high place, the labor cost for replacement and maintenance is high, the power of the ultraviolet lamp is required to be reasonably designed, a certain ultraviolet dose allowance is reserved, the ultraviolet intensity is also required to be monitored in real time, the power of the ultraviolet lamp is dynamically regulated, and maintenance personnel is timely informed of replacement and maintenance of the lamp when the ultraviolet dose is insufficient.
The antibacterial and degerming air purifier is usually formed by combining components such as a coarse-effect filter, a high-voltage electrostatic plasma dust-removing sterilizer, an ultraviolet lamp, a photocatalyst catalyst, a high-efficiency filter and the like, a proprietor can select one or more of the components to be installed according to the needs, the components are required to be cleaned or replaced regularly or irregularly, and otherwise, the antibacterial and degerming performance is reduced, and the using effect is influenced. For ultraviolet lamp adopting mercury lamp technique, there is also risk that mercury is revealed, and its ultraviolet irradiation intensity must drop by a wide margin before mercury is revealed, so detect ultraviolet irradiation intensity and not only can ensure ultraviolet lamp's normal use, can also prevent mercury and reveal the risk.
Although high efficiency filters can only intercept and not kill pathogens thoroughly in time, some pathogens (including new coronaviruses) die after a prolonged residence time on the filter screen. In view of biosafety, it is preferable to install an ultraviolet lamp in front of the filter and take out for replacement after at least 1 hour of irradiation of ultraviolet rays after the fan stops operating, or take out and dispose of properly in accordance with biosafety-related regulations with special protective equipment. The photocatalyst catalyst needs to generate Reactive Oxygen Species (ROS) and free radical oxidizing microorganisms under the action of light to achieve the effect of killing. Therefore, the ultraviolet lamp can make the high-efficiency filter and the photocatalyst catalyst exert better antibacterial and degerming performance, and the real-time monitoring of the ultraviolet intensity is particularly important.
At present, no special software and hardware system can monitor the ultraviolet irradiation intensity in real time, control the opening and closing of the ultraviolet lamp, record the running time of the ultraviolet lamp in the air purifier and the installation and cleaning or replacement date of each part needing cleaning or replacement, and remind the owners of cleaning or replacement each part in time.
