The presence of dust will affect the disinfection effect, and different disinfection methods have different inactivation effects on pathogens and need a certain time. Ultraviolet physical inactivation can only inactivate pathogens within the light range, chemical reagents can accompany pathogens but high concentration will cause damage to the human body, and pathogens cannot be fully inactivated after aggregation, which will increase the concentration of pathogens.

[0027] Further, as a preferred, the dehumidification mesh is a cylindrical filter paper with different diameters, which is sequentially sleeved from large to small, and is arranged at intervals with the annular notches, and multiple annular notches are arranged at the bottom of the partition plate, and the upper part is a spiral sector.

[0028] Compared with the prior art, the present application provides an intelligent disinfection equipment for biological aerosols, which has the following

[0029] Beneficial effects:

[0030] 1. In this invention, a filter screen is set in the physical disinfection layer to filter and disinfect bioaerosols. The filter screen has large pores to ensure efficient air passage and mainly filters dust while also filtering some pathogens. The filter screen is composed of multiple narrow and long mesh strips that are stacked in multiple layers. The mesh strips are inclined, forming inclined gaps between them and the fixed rods. A diamond-shaped gap is formed in the middle. When the amount of dust filtered by the equipment reaches a certain level, the dust will accumulate at the bottom of the inclined gap and the diamond-shaped gap. The surface inside the filter screen can still be filtered by air. Compared with one or more horizontally arranged filters, it is less prone to clogging, more efficient and effective. When there is less dust in the bioaerosol, filter yarn can be filled into the diamond-shaped gap to improve the filtration effect and reduce the concentration of pathogens in the exhaust air. At the same time, inactivation is achieved by irradiation lamps.

[0031] 2. In this invention, the dehumidifier shell is fixed to the lower end of the fan, and the upper part of the partition plate is close to the fan. The upper part guides the airflow spirally through the annular groove. The airflow continuously enters within the interval formed by the dehumidifier mesh and circulates in the annular space. After passing through layers of dehumidifier mesh, it is discharged. The airflow circulates within the interval formed by the dehumidifier mesh and fully contacts the entire cylindrical surface of the dehumidifier mesh, filtering out some pathogens and some chemical reagents. The filtered water flows downward and collects in the collection tank. The chemical reagents inactivate the pathogens. On the one hand, the chemical reagents enhance the adhesion ability of the pathogens and are adsorbed onto the dehumidifier mesh, meeting the condition that the chemical reagents need a long time to inactivate the pathogens. On the other hand, it avoids the chemical reagents being discharged into the air and causing harm to people. Finally, dehumidification is completed and the concentration of pathogens discharged into the air is further reduced. Attached Figure Description

DETAILED DESCRIPTION

[0038] Please refer to Figures 1-4 In the embodiment of the present application, a biological aerosol intelligent disinfection device comprises:

[0039] The rack 1 is provided with an inlet 3 at the upper end and an outlet 4 at the lower end.

[0040] The machine box 2 is fixed inside the rack 1.

[0041] The physical disinfection layer 5 is fixed inside the rack 1 below the inlet 3 and communicates with the inlet 3.

[0042] The chemical disinfection layer 6 is fixed at the upper end of the physical disinfection layer 5 and is provided with a fan 7 at the lower end.

[0043] The dehumidification layer 8 is fixed at the end of the fan 7 away from the chemical disinfection layer 6, and the lower end of the dehumidification layer 8 communicates with the outlet 4.

[0044] It should be explained that when biological aerosol disinfection is carried out to inactivate pathogens therein, the types of pathogens inside the aerosol are different and also include dust. Filtration disinfection cannot inactivate pathogens, and the presence of dust will reduce the disinfection effect. Through a single means of disinfection, it is difficult to achieve satisfactory results. The physical disinfection layer 5 and the chemical disinfection layer 6 work together to improve the disinfection effect and efficiency of the device.

[0045] As a preferred embodiment, the chemical disinfection layer 6 continuously sprays water mist of a certain concentration of disinfectant.

[0046] In this embodiment, as Figure 2 The physical disinfection layer 5 comprises:

[0047] The fixed shell 51 is fixed inside the rack 1 and is provided with grooves on both sides.

[0048] The support frame 52 is symmetrically arranged in two groups, and the two ends are fixed in the grooves. The support frame 52 is placed with partition blocks 53 in the grooves.

[0049] The filter screen 55 is fixed with multiple fixed rods 54 at the upper and lower ends, and the fixed rods 54 are fixed with the support frame 52.

[0050] The irradiation assembly 56 is symmetrically arranged in two groups and fixed at both sides of the fixed shell 51, so that the filter screen 55 is between the irradiation assemblies 56.

[0051] As a preferred embodiment, the filter screen 55 is selected to have large pores, is made of rigid material, and is composed of a plurality of narrow and long gauze strips arranged in a staggered manner. The gauze strips are inclined and form inclined gaps between the gauze strips and the fixed rods 54, and rhombic gaps are formed in the middle.

[0052] It should be explained that the filter screen 55 in the physical disinfection layer 5 is arranged to filter and disinfect the biological aerosol. Different filter materials with different pore sizes are usually used to filter biological aerosol according to the size of different pathogens. The filtering efficiency is related to the pore size of the filter material. The smaller the pore size, the greater the air resistance, and only the filtering effect can be achieved. The presence of dust makes the filtering effect worse. The filter screen 55 selected in the device has large pores to ensure the efficiency of air passing through. At the same time, the filter screen 55 is composed of a plurality of narrow and long gauze strips arranged in a staggered manner to form multiple layers of superposition and strengthen the filtering effect. The filter screen 55 group filters dust and filters part of the pathogens.

[0053] It should be explained that the gauze strips are inclined and form inclined gaps between the gauze strips and the fixed rods 54, and rhombic gaps are formed in the middle. When the dust filtered by the device reaches a certain amount, it will gather downward under the action of gravity, showing that the dust gathers at the bottom of the inclined gap and the rhombic gap. The surface inside the filter screen 55 can still be filtered by air. Compared with one or more horizontally arranged, it is not easy to block and has higher efficiency and better effect. When the dust in the biological aerosol is less, the filter gauze can be filled in the rhombic gap to improve the filtering effect and reduce the concentration of pathogens in the discharged air.

[0054] In this embodiment, the irradiation assembly 56 includes: Figure 3

[0055] The lamp shell 561 is fixed on the fixed shell 51.

[0056] The irradiation lamp 562 is fixed in the middle of the lamp shell 561.

[0057] The reflection plate 563 is arranged in two groups and fixed in the lamp shell 561, and is symmetrically arranged about the irradiation lamp 562.

[0058] As a preferred embodiment, the irradiation lamp 562 is an ultraviolet lamp, and the reflection plate 563 is arranged to focus the light emitted by the irradiation lamp 562, so that the light is concentrated in the space where the filter screen 55 is located, and irradiates all surfaces inside and outside the filter screen 55 through the inclined gaps and the rhombic gaps.

[0059] ​It needs to be explained that the irradiation lamp 562 under the focusing of the reflecting plate 563 ensures that the ultraviolet light irradiated on the filter screen 55 is more sufficient, and the existence of the inclined gap and the rhombic gap inside the filter screen 55 makes the whole surface of the filter screen 55 can be fully irradiated by ultraviolet light before the filter screen 55 accumulates dust, after the filter screen 55 accumulates dust or after the rhombic gap fills the filter screen, ensures that the inside of the filter screen 55 is fully inactivated.

[0060] In this embodiment, as Figure 4 , the dehumidification layer 8 comprises:

[0061] The dehumidification shell 81 is fixed at the lower end of the fan 7, and a liquid collecting groove 85 is arranged inside the dehumidification shell 81 near the lower end;

[0062] The partition plate 82 is coaxially fixed inside the dehumidification shell 81, and a plurality of annular grooves 83 are formed in the partition plate 82; and

[0063] The dehumidification net 84 is arranged as a plurality of dehumidification nets fixed between the liquid collecting groove 85 and the partition plate 82.

[0064] As a preferred embodiment, the dehumidification net 84 is a cylindrical filter paper with different diameters, which is sequentially sleeved from large to small, and is arranged in the annular groove 83, and a plurality of annular grooves 83 are formed in the bottom of the partition plate 82, and the upper part is a spiral sector.

[0065] It needs to be explained that the dehumidification shell 81 is fixed at the lower end of the fan 7, and the upper part of the partition plate 82 is close to the fan 7, and the upper part of the partition plate 82 guides the airflow to spiral through the annular groove 83, and the airflow continuously enters the space formed by the dehumidification net 84 and flows in the annular space, and after passing through the dehumidification net 84, the airflow is discharged, and the airflow flows in the space formed by the dehumidification net 84 and fully contacts the whole cylindrical surface of the dehumidification net 84, filters out part of the pathogens and part of the chemical reagents, and the filtered water flows downward and collects in the liquid collecting groove 85, inactivates the pathogens by the chemical reagents, on the one hand, the chemical reagents improve the adhesion ability of the pathogens and are adsorbed on the dehumidification net 84, meet the condition that the chemical reagents inactivate the pathogens for a long time, on the other hand, avoid the chemical reagents from being discharged into the air to harm the personnel, and finally complete the dehumidification and further reduce the concentration of pathogens discharged into the air.

[0066] In specific implementation, the filter screen 55 in the physical disinfection layer 5 is arranged to filter and disinfect the biological aerosol. The filter screen 55 adopts large pores to ensure the efficiency of air passing, and is composed of multiple narrow and long gauze strips staggered to form multiple layers of superposition. Dust is filtered, and part of the pathogen is filtered at the same time. When the dust filtered by the equipment reaches a certain amount, the dust is accumulated at the bottom of the inclined gap and the rhombic gap. The surface inside the filter screen 55 can still be filtered by air. When the dust in the biological aerosol is less, the filter screen can be filled in the rhombic gap to improve the filtering effect. The irradiation lamp 562 ensures that the ultraviolet light irradiated on the filter screen 55 is more sufficient under the focusing of the reflecting plate 563, so as to ensure that the inside of the filter screen 55 is fully inactivated. The air flow spirally passes through the annular slot 83 guided by the partition plate 82, and continuously enters the space formed by the dehumidification net 84 while flowing in the annular space. After passing through the dehumidification net 84 layer by layer, the air flow is discharged. The filtered water flows downward and is accumulated in the liquid collecting tank 85, and the whole disinfection process is completed.

[0067] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
