Description
Technical Field
The invention relates to a sterilization device, in particular to an ultraviolet sterilization device.
Background
The ultraviolet sterilization and disinfection is to use ultraviolet with proper wavelength to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of the microorganism body, so as to cause the death of growing cells and/or regenerative cells, thereby achieving the effect of sterilization and disinfection. The ultraviolet disinfection technology is based on modern epidemic prevention science, medicine and photodynamics, and utilizes specially designed UVC wave band ultraviolet light with high efficiency, high intensity and long service life to irradiate flowing water so as to directly kill various bacteria, viruses, parasites, algae and other pathogens in the water.
Research shows that ultraviolet ray can kill microbes through the radiation damage to microbes and the destruction of nucleic acid, so as to reach the aim of disinfection. The action of ultraviolet light on nucleic acids can result in bond and strand breaks, interstrand cross-linking, and the formation of photoproducts, among other things, thereby altering the biological activity of DNA to render microorganisms unable to replicate themselves, and this ultraviolet damage is also lethal.
The ultraviolet ray can kill various microorganisms including bacteria propagules, spores, mycobacteria, viruses, fungi, rickettsia, mycoplasma and the like, and all surfaces polluted by the microorganisms can be disinfected by the ultraviolet ray, water and air. However, since ultraviolet irradiation energy is low and penetration is weak, only microorganisms directly irradiated thereto can be killed, and thus, it is necessary to sufficiently expose the sterilized portion to ultraviolet rays during sterilization.
The ultraviolet sterilizing lamp has the working principle that the ultraviolet sterilizing lamp acts on DNA of microorganisms to destroy the structure of the DNA, so that the DNA loses the functions of reproduction and self-replication, thereby achieving the aim of sterilization and disinfection. The actual bactericidal action is UVC ultraviolet ray, because the C-band ultraviolet ray is easily absorbed by the DNA of the organism, and the ultraviolet ray of about 253.7nm is the best. The germicidal effect is determined by the dose of radiation received by the microorganisms and is also related to the output energy of the ultraviolet radiation, the type of lamp, the intensity of the light and the duration of use. The ultraviolet irradiation dose refers to the amount of ultraviolet rays with specific wavelength required when a certain bacteria inactivation rate is reached, the larger the irradiation dose is, the higher the sterilization efficiency is, the main factor influencing the sufficient ultraviolet irradiation dose received by the microorganisms is the light transmittance, and when the UVC output intensity and the irradiation time are fixed, the actually received dose of the microorganisms changes along with the change of the light transmittance.
Existing uv sterilization equipment is generally classified into: the closed chamber type is provided with a closed chamber, can disinfect the surface of an object in the closed chamber, has small space and relatively concentrated radiation, and does not harm surrounding users; the open type is used for sterilizing the surfaces of air and articles placed in a room, a high-power ultraviolet lamp is needed, and meanwhile, because the space is large, the radiation is relatively dispersed, the irradiation time is long, and the surrounding users are injured when the ultraviolet lamp is used. In addition, the ultraviolet lamp is combined with the cavity in the traditional air purifier, and air passes through the area irradiated by the ultraviolet lamp to be sterilized, but the structure has short air irradiation time, so that germs cannot be effectively killed without receiving enough irradiation dose; and if a multi-stage cavity structure is adopted, although the air retention time can be prolonged, the ultraviolet lamp is very difficult to arrange, so that a plurality of dead angles which cannot be irradiated exist, and pathogenic bacteria are easy to gather. How to ensure that ultraviolet rays can sufficiently and effectively kill germs is an urgent technical problem to be solved.
