Description
Technical Field
The utility model relates to a sanitary safety equipment technical field especially relates to a quick pulse highlight degassing unit that disinfects.
Background
The deep ultraviolet with the wavelength less than 280nm can cause the coagulation and the denaturation of biological protein and the DNA or RNA breakage of biological genetic material, thereby leading the death of microorganisms and the inactivation and desensitization of sensitized protein. Experts in the prevention and control center of Chinese diseases in SARS find that the use strength is more than 90 muW/cm2Can kill SARS virus by irradiating coronavirus for 30 min. In the diagnosis and treatment of pneumonia infected with a novel coronavirus (trial fifth edition), it was pointed out that the novel coronavirus was sensitive to ultraviolet rays. Recent studies have found that the novel coronavirus is associated with the SARS coronavirus. Therefore, the coronavirus can be effectively inactivated theoretically by scientifically and reasonably using the ultraviolet rays.
The required ultraviolet dose is different according to different types of objects to be killed. When the ultraviolet intensity is 30000 mu W/cm2The time for killing virus, bacteria, mold spores, algae and other microorganisms is 0.1-1.0S, 1.0-8.0S and 5.0-40.0S respectively. The ultraviolet dose plays an important role in the sterilization process, the ultraviolet dose can be expressed as the product of the ultraviolet intensity and the irradiation time, and when the dose is the same, a high-intensity short-time or low-intensity long-time irradiation mode can be adopted to achieve the sterilization purpose. Under the condition of sufficient ultraviolet dose, the inactivated virus and bacteria can not be reactivated, but when the ultraviolet dose is insufficient, a plurality of virus and bacteria inactivated by irradiation can repair self-damaged structures through the assistance of light. Therefore, the ultraviolet dose affects the ultraviolet sterilization effect.
In addition, related studies have shown that the survival rate of bacteria increases from 6.4% to 24% when the relative humidity of the air rises from 25% to 75%. It is generally evaluated that the UV ray sterilization dose is usually based on 60% relative humidity, and when the humidity is increased, the UV ray dose should be increased correspondingly because the sterilization effect is reduced. For example, when the indoor relative humidity is 70%, 80% and 90%, respectively, the ultraviolet dose needs to be increased by 50%, 80% and 90%, respectively, to achieve the same sterilization effect. The change of the environmental humidity directly influences the microorganism killing efficiency, and the ultraviolet dose needs to be adjusted according to the environmental humidity, so that the effective sterilization requirement is met. Therefore, the environmental humidity affects the ultraviolet sterilization effect.
The traditional ultraviolet sterilization adopts a low-pressure mercury lamp, and performs space irradiation sterilization by using 253.7nm ultraviolet wavelength generated by mercury element excitation, wherein the sterilization time needs to last for hours, the action time is slow, and human and machine can not coexist. Meanwhile, the time required by the low-pressure mercury lamp from starting to stabilizing is long, generally several minutes, the low-pressure mercury lamp is greatly influenced by the environmental temperature, the service life is quickly attenuated, and the mercury element contained in the low-pressure mercury lamp has the problems of broken pollution risk and environmental influence of later-stage scrapping treatment.
In the 70 s of the 20 th century, the idea of using a pulsed xenon lamp as a surface sterilizing device for food packaging materials was proposed. In 1984, patents on the pulsed xenon lamp sterilization technology were registered in the united states, and in the following years, experiments for the pulsed xenon lamp technology to sterilize the surface of an object were gradually developed. At the end of the 90 s in the 20 th century, pulsed xenon lamp sterilization equipment gained acceptance in the food production management industry, and subsequently, pulsed xenon lamp sterilization technology began to be popularized in the field of food packaging. Meanwhile, the first pulse xenon lamp sterilization instrument used in the medical and health field is researched and developed in Japan. Since the 21 st century, the pulsed xenon lamp sterilization technology gradually shows good application prospects in the aspects of medical treatment, water treatment, air sterilization and the like.
The pulse xenon lamp device can emit strong pulse flash light from ultraviolet ray to infrared ray in spectrum similar to that of solar spectrum and instantaneous intensity several thousand times that of sunlight. The pulse high light has the characteristics of high light radiation intensity, and the spectrum range emitted by the pulse xenon lamp is wide and can cover the spectrum of 100-1100 nm. Through reasonable design and adjustment of driving parameters of the pulse xenon lamp tube, high peak values are obtained in an UV-C part (with the wavelength of 200-280 nm), a visible light part (with the wavelength of 400-760 nm) and an infrared part (with the wavelength of 760-1000 nm), visible light and infrared light output by the pulse xenon lamp can also be combined with high-energy pulse strong light to kill microorganisms, namely, the flash heating effect is utilized to passivate enzymes and other components of cells, and the pulse effect is utilized to damage cell walls and other components of the cells to cause bacterial death. Therefore, the pulse ultraviolet and the strong light emitted by the pulse xenon lamp are different from the common ultraviolet sterilization mechanism in the sterilization mechanism, the pulse ultraviolet and the strong light not only have the photochemical action and the photothermal action in the sterilization process, the sterilization process is more complicated, and the sterilization of the pulse ultraviolet and the strong light on microorganisms mainly has four ways: 1. destroying the cell membrane of the microorganism; 2. decomposition of enzymes in the microorganism; 3. disrupting the genetic material nucleic acid in the microbial cell; 4. photothermal action causes microbial cells to swell, resulting in cell disruption. Therefore, the pulse xenon lamp can kill microorganisms from multiple aspects, and has good prospect in the technical field of sterilization and disinfection.
However, the high-power instantaneous ultraviolet radiation contained in the pulsed ultraviolet light may also damage eyes and skin, which causes aging of the polymer material, and shows yellowing, cracking and structural strength reduction, so to apply the pulsed ultraviolet light and the high-power ultraviolet light to rapid sterilization in a human-computer coexistence environment, firstly, the safety problem needs to be solved, including: 1. UVC leakage control; 2. possible malfunctions result in light being directed directly at the eye; 3. the radiation dose control of the damage of the radiation to the surface of an object, in particular the damage to the surface of a high polymer material.
Chinese utility model patent application 2017109567139 discloses a pulse xenon lamp ultraviolet sterilization appearance utilizes powerful pulse xenon lamp and elevating gear, microorganism detection device to disinfect to the space, has replaced traditional low pressure mercury lamp in essence, carries out pulse space and disinfects, nevertheless can not man-machine coexistence, even near can not someone when using, and inconvenient carrying.
In medical environments, such as bedrails, call buttons, switches, tray tables, toilet seat rings, masks, shoes and the like in hospitals, elevator switches and handrails in public places, door handles, water taps and lighting switches in families, fruits, vegetables, bathrooms, cleaning supplies and the like used in daily life are required to be sterilized and disinfected quickly and conveniently, and the requirement of portability is also provided. The traditional disinfection water cleaning mode is tedious and low in efficiency, the time required by the traditional low-pressure mercury lamp is long, and the traditional low-pressure mercury lamp cleaning mode cannot be used for quickly sterilizing and disinfecting. The pulse xenon lamp is a better solution, but the pulse xenon lamp ultraviolet sterilizer in the prior art can not coexist in man-machine and is inconvenient to carry, and obviously can not meet the requirements of frequent use and portability in the epidemic period.
