Description

Spraying disinfection device

Technical Field

The invention relates to the technical field of article disinfection, in particular to a spraying disinfection device.

Background

In order to effectively block the transmission of germs and infection sources from the sources, a plurality of disinfection devices are arranged in various public places such as airports, ports, railways, passenger stations and the like to disinfect the luggage of passengers. The following three types of sterilization schemes (for sterilizing the surface of an object) are currently in the market:

(1) high-pressure pump sprays technique, because of the consideration of atomization effect and cost, adopt fixed water pressure, the flow of every shower nozzle is fixed, and mechanical atomizing's shower nozzle aperture also is fixed setting, to the regulation of the required discharge change of different use scenes, can only realize through adding and deleting the shower nozzle, the flexibility is relatively poor, and adopt high-pressure pump atomizing to spray the regulation to shower nozzle discharge limited, for example, to airport luggage processing system, the required discharge control of the disinfection on luggage surface is stricter, this kind of method spun water droplet diameter granule is great, in case the flow is too big, can cause the luggage surface to be drenched, cause the trouble for the passenger, and simultaneously, the liquid medicine consumes the volume greatly, and the cost is higher, the feature of environmental protection is not enough. In addition, the high pressure of the high-pressure spraying system can cause leakage of the loaded solution, the safety has risks, the matched valve elements have high cost, and the fluid control is relatively difficult to realize.

(2) The ultrasonic atomization disinfection scheme atomizes solution into 1um to 5um tiny fog particles, the fog particles are sprayed into air through pressurization, dry fog is diffused to an area needing disinfection to complete the disinfection process, the disinfection process can only be used for space disinfection, a certain target object cannot be disinfected accurately, the disinfection coverage is not accurate, and the use scene is limited. When the scheme is used for disinfecting the surface of an object, the effect is poor, and as the diameter of the fog drops sprayed by the atomization method is smaller than 10 microns, small drops can bounce off the surface of the object and cannot crack or adhere to the surface of the object to make the surface wet, so that the disinfection effect is limited because the surface of the object cannot be basically wetted in a limited time. At present, no authoritative detection report can prove the killing effect of the equipment on the surface of the object, which is declared to be related to the killing of the surface of the object by the dry fog, exists in the market.

(3) The ultraviolet disinfection proposal, the ultraviolet sterilization effect is determined by the irradiation dose received by the microorganism in unit time, the irradiation dose required by different microorganisms to be killed has larger difference, and the output energy of the ultraviolet ray is related to the type, light intensity and service time of the ultraviolet ray lamp, the moving speed of the luggage is fast, and due to factors such as equipment size requirement and work flow, the illumination time of the luggage items by the existing ultraviolet lamps on the market is averagely several seconds, in addition, the surface of the object to be sterilized is away from the ultraviolet ray by a certain distance, so that the sterilization effect is influenced by the illumination output intensity of the lamp tube, and the ultraviolet lamp is easy to age, gradually loses 30-50% of light intensity along with the increase of the using times, so that the sterilization effect is greatly reduced, and the sterilization effect is unstable. At present, in the fields of cold chain and airport disinfection and the like, the application effect of UVC ultraviolet disinfection in the cold chain and airport industry is lack of authoritative data support.

Along with the continuous change of epidemic situation, the three disinfection schemes can not meet the disinfection requirements of airports, ports, railways, passenger stations and other large places on the surfaces of articles, and the workload of workers is increased due to the fact that the flow of people is large and the required disinfection amount of the articles is large, and the disinfection is not comprehensive enough, and partial dead corners of the articles are difficult to disinfect and need to be improved.
