Description
Technical Field
The invention relates to the technical field of article sterilization, in particular to a spray sterilization device.
Background
The main current sterilization schemes (sterilization of the surface of the object) in the market are as follows:
(1) The high-pressure pump spraying technology adopts fixed water pressure for the consideration of atomization effect and cost, the flow of each spray head is fixed, the aperture of the spray head for mechanical atomization is also fixedly arranged, the adjustment of water flow change required by different use scenes can only be realized by adding and deleting spray heads, the flexibility is poor, the adjustment of water flow of the spray heads by adopting high-pressure pump atomization spraying is limited, for example, the water flow control required by the sterilization of the luggage surface is stricter for an airport luggage processing system, the diameter particles of water drops sprayed by the method are larger, once the flow is overlarge, the luggage surface can be wetted, the trouble is caused for passengers, meanwhile, the consumption of liquid medicine is large, the cost is higher, and the environmental protection performance is insufficient. In addition, the high pressure of the high pressure spray system can cause the loaded solution to leak, the safety is at risk, the cost of the matched valve elements is high, and the fluid control is relatively difficult to realize.
(2) The scheme of ultrasonic atomization disinfection, this scheme atomizes into 1um to 5 um's tiny fog grain with the solution, and fog grain is sprayed to the air through the pressurization, and to the regional diffusion dry fog of needs disinfection accomplish disinfection process, often can only be used to space disinfection, can not realize a certain target object of accurate disinfection, and the disinfection covers the face imprecisely, uses the scene limited. The solution is poor in effect when the surface of an object is disinfected, and as the diameter of mist drops sprayed by the atomization method is smaller than 10um, small drops can be sprung from the surface of the object and cannot break or adhere to the surface to moisten the surface, the surface of the object is disinfected, and the surface of the object cannot be moistened basically within a limited time, so that the disinfection effect is limited. At present, devices which claim to be used for killing the surface of an object by dry fog exist on the market, and basically no authoritative detection report can prove the killing effect.
(3) 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 eliminated has larger difference, the output energy of ultraviolet rays is related to the type, the light intensity and the service time of ultraviolet lamps, the moving speed of luggage articles is high, the existing ultraviolet lamps on the market average the illumination time of the luggage articles for a few seconds under the factors such as equipment size requirement, workflow and the like, in addition, the surface of the sterilized object has a certain distance from the ultraviolet rays, so that the sterilization effect is influenced by the illumination output intensity of a lamp tube, and the ultraviolet lamps are easy to age, gradually lose 30% -50% of light intensity along with the increase of the using times, so that the sterilization effect is greatly discounted, and the sterilization effect is unstable. At present, in the fields of cold chain, airport disinfection and the like, the application effect of UVC ultraviolet disinfection in the cold chain and airport industries is also lacking in authoritative data support.
The three disinfection schemes can not meet the disinfection requirements of various places such as airports, ports, railways, passenger stations and the like on the surfaces of the articles gradually, and because the traffic of people is large, the required disinfection quantity of the articles is also large, the workload of workers is increased, the disinfection is not comprehensive enough, dead angles of parts of the articles are difficult to disinfect, and the improvement is needed.
