Description
Technical Field
The invention relates to the technical field of ultraviolet lamp disinfection, in particular to a method for maintaining a disinfection ultraviolet lamp, and further relates to a system and a device for maintaining the disinfection ultraviolet lamp.
Background
Ultraviolet radiation is an proven effective physical disinfection method for pathogenic microorganisms, and compared with chemical disinfection, the ultraviolet radiation disinfection method has the advantages of no secondary pollution, instant use, high efficiency and convenience.
Uv lamps are a core element of such disinfection products and must be routinely maintained in order to ensure effective disinfection power and dosage. The first aspect of maintenance is the daily cleaning of the lamp tube, which is mainly represented by the adhesion and accumulation of greasy dirt and dust on the glass surface of the lamp tube due to daily natural accumulation, and particularly comprises the ambient electrostatic adsorption and the like caused by the on-off operation of an ultraviolet lamp. Because the penetration force of ultraviolet rays is very weak, the power of the radiated ultraviolet rays is directly reduced by the oil dirt and dust attached to the surface of the lamp tube. Ultraviolet disinfection users such as hospitals generally arrange special staff to perform cleaning and maintenance work of ultraviolet lamp tubes, but when the users need cleaning, whether the cleaning reaches the standard and the like are judged by human subjectivity, and scientific detection and decision are lacked. A second aspect of maintenance is the replacement of the lamp at the end of its life, i.e. the objective natural decay of the radiant power of the uv lamp over time, when the radiant power decays below a certain threshold (e.g. to meet a country-relevant standard), a new lamp has to be replaced, i.e. as indicated by monitoring the lamp life. The life expectancy of the lamp tube is generally marked when the lamp tube leaves a factory, but the life expectancy is only based on statistical estimation, and the actual life is influenced by various factors, particularly the quality management levels of different manufacturers are different. A third aspect of maintenance is the replacement of faulty lamps (e.g. short or open lamps), especially in intelligent uv disinfection systems, where autonomous fault detection is necessary to actively remind maintenance personnel to replace new lamps in time, thereby ensuring continuous disinfection. In the traditional method, maintenance personnel can replace the lamp tube after patrolling and detecting a fault, prompt and replacement cannot be realized in time, and uninterrupted coverage of disinfection cannot be realized.
