Embodiment Construction
[0032] A three-stage refinement method for disinfectant vapor of the present invention, first, utilizes ultrasonic atomization technology to carry out primary atomization on disinfectant liquid; secondly, utilizes mixing refinement technology to impact hot air and disperse disinfectant atomized gas, Use the airflow to collide, cut, and break the atomized gas, effectively break the disinfectant atomized gas molecular clusters, and refine the disinfectant atomized gas twice; finally, use the evaporation technology to mix the disinfectant and air with the inner wall of the evaporator Full contact, heating and evaporation make the atomized gas three times thinner, so as to achieve the purpose of outputting disinfectant vapor of ultrafine particles.
[0033] Such as figure 1 As shown, the disinfectant vapor three-stage refining system for realizing the above method includes: an ultrasonic atomization device 1, a mixing and refining device, an evaporator 3 and a control system. The...

Provided are a three-level refining method and a system for disinfectant steam. The three-level refining method comprises the steps of firstly using ultrasonic atomization technology to primarily atomize disinfectant liquid; secondly, utilizing mixed refining technology to shock hot air to scatter disinfectant atomization gas, utilizing air flow to lead the atomized gas to be crashed, cut and broken, effectively breaking molecular groups of disinfectant atomization gas, and secondarily refining disinfectant atomization gas; finally, using efficient steam technology to enable mixed gas of disinfectant and air to be fully in contact with the inner wall of an evaporator to be heated to be evaporated, enabling the atomization gas to be refined thirdly, and achieving the purpose of inputting super fine grain disinfectant steam. The three-level refining method and the system for disinfectant steam use method combination of ultrasonic atomization, air flow milling and an evaporation three-level refining method to obtain micron disinfectant steam grains, thereby remarkably improving decontamination effect and decontamination efficiency when the disinfectant steam serves as decontamination steam.
Description
technical field [0001] The invention relates to a three-stage refinement method and system for disinfectant steam, which is mainly used in the field of disinfectant steam sterilization. Background technique [0002] The currently used steam disinfection technologies mainly include formaldehyde vapor, gaseous chlorine dioxide and hydrogen peroxide and other disinfectant vapors. Vapor hydrogen peroxide (VHP) can oxidize many microorganisms including bacterial spores, and at the same time, it is much less harmful to public health than formaldehyde. VHP is produced by evaporating 30-50% of a disinfectant solution. Since the disinfectant is finally decomposed into water and oxygen by catalysis, it will not pollute the product and the environment while disinfecting. VHP technology has been used in medicine, biology and pharmaceutical industry for more than ten years, and has gradually developed into a mainstream disinfection technology. Many VHP generators are now commercially ...
