Circulating air chemical filtering sterilizing equipment and integrated mobile sterilizing equipment

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to circulating air chemical filtration disappears and kills equipment and integration removal disinfecting equipment.

Background

The new coronavirus is a brand new challenge for human survival due to high pathogenicity, invisibility of infection and difficult inactivation, and the existing sterilization technology, disinfection standard specification and the like cannot effectively meet the challenge of the new coronavirus. The research and test of Jilin university shows that after the treatment of ultraviolet disinfection and alcohol disinfection according to the current national standard and operation specification, the ward of the new crown patient in hospital still has the new crown virus residue on the object surface and in the air.

The ultraviolet disinfection is to destroy RNA and DNA structures on the surfaces of viruses and bacteria, can kill the viruses and bacteria in the air and on the surfaces of objects under the condition of meeting the light wave intensity, but cannot achieve the purpose of killing when the ultraviolet radiation cannot reach the place and the light wave intensity is insufficient, and in addition, the ultraviolet radiation can cause harm to human bodies and can be applied only in an unmanned state.

Ozone is a strong oxidant, can destroy RNA and DNA structures on the surface layers of bacteria and viruses after the concentration of ozone in the air reaches a certain standard, so that the purpose of killing the bacteria and viruses on the surfaces of the air and objects is achieved, and the ozone is transmitted through the air and is not influenced by shielding and small-amplitude distance change. However, ozone stimulates respiratory tracts of human bodies, has peculiar smell and can only be applied in an unmanned state.

The current national regulation of ultraviolet disinfection duration is 30-60 minutes, ozone disinfection duration is 30 minutes for air disinfection and 120 minutes for object surface disinfection. The long time for disinfection causes low disinfection efficiency and huge workload in application, and the disinfection workload and the operation difficulty are increased greatly undoubtedly when the sickrooms in the whole floor or building need to be vacated frequently.

In the face of the brand-new high-difficulty inactivated virus, on the basis of the simultaneous application of the multiple means, the application adopts higher virus killing strength than the traditional standard, and can achieve the purpose of killing the new coronavirus. In view of the fact that basic scientific research to date does not provide any scientific research data for killing new coronavirus, the application can improve the strength of the killing technology by times.

Detailed Description

In order to better explain the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

The technology provides a solution for thoroughly sterilizing and disinfecting the surfaces of air and objects in small and medium-sized limited spaces. The multi-finger area of the small and medium-sized finite space is less than 100m²Volume of less than 400m³Such as a building space or a cabin space. The application of the technology in small and medium-sized limited spaces mainly solves the problem that the people are susceptible to infection caused by intensive contact of the people or the problem that the people are susceptible to infection due to high density of virus and bacteria in the spaces. By applying the technology, the air and objects in the unmanned state space can be thoroughly disinfected and killed by surface bacteria and viruses, and the air flowing through the product of the technology in the manned state space can be disinfected and sterilized by circulating the air, so that the reduction of the viruses and bacteria in the space is realized, and the infection rate of diseases is reduced.

Ultraviolet disinfection lamps and ozone disinfectors are common, but a disinfection device form integrating the two technologies is an innovation. The two technologies are applied independently and have certain limitation, the ultraviolet disinfection effect is limited by the shielding object and the distance, and the ozone disinfection effect is influenced by the concentration unevenness caused by the influence of air flow. And the two technologies are applied simultaneously, so that mutual compensation can be realized, and the disinfection effect is enhanced. On the basis, the air circulation chemical filter screen is added for disinfection, so that the disinfection capability is further improved.

The three disinfection technologies are applied simultaneously after the ultraviolet and ozone disinfection intensity is greatly improved, in the current disinfection technology, the result of the most thorough disinfection and sterilization on the surfaces of air and objects can be achieved, the disinfection and sterilization capability is greatly improved, and a limited indoor relatively safe space can be created for human beings when strong viruses such as new corona are faced.

The overall structure schematic diagram of the sterilizing vehicle of the utility model is shown in figure 1, and comprises an ultraviolet sterilizing device 1, an ozone sterilizing device 2 and a circulating air chemical filtering sterilizing device 3; when the three disinfection technologies are applied simultaneously, the disinfection and sterilization duration can be greatly shortened, and great convenience and great improvement of efficiency are brought to practical application. The product of the technology has the goal of killing 20-30m in 10 minutes²The high-infection sickroom is completely killed.

The product can be applied in three sterilization modes at the same time under the full load state, can be optionally applied in a combination of two modes according to the environment and the requirement, and can also start a single sterilization mode.

1) Structural design of ultraviolet disinfection equipment

Once the current civilian ultraviolet lamp product is settled and mostly is a single tube and shines the position and use, but medical ultraviolet lamp product is that double-barrelled single telescopic link is rotatable every single move and adjusts the application. The two application modes can not avoid the inherent limitation of the ultraviolet lamp tube, namely weak light emission in the directions of two ends of the axis of the lamp tube, and can not play a role in sterilization. Therefore, the product is only a local sterilization device, and cannot be called a space sterilization device.

The ultraviolet disinfection and sterilization device 1 of the present application employs two retractable, rotatable and pitching brackets 22, so that two lamps 21 can be respectively positioned in a staggered manner in the horizontal and vertical dimensions, and the two lamps compensate for the weak light-emitting area, thereby achieving complete disinfection and sterilization in the space, as shown in fig. 2.

In addition, a single 15-30W lamp tube is mostly adopted by the civil ultraviolet lamp, and two 30W lamp tubes are mostly adopted by the medical ultraviolet lamp. The ultraviolet disinfection and sterilization equipment adopts 2 150W standard 254nm wavelength ultraviolet lamp tubes, and the sterilization and disinfection intensity is greatly improved. The ultraviolet ray with 254nm wavelength is the best wavelength for sterilization.

2) Circulating air chemical filtering sterilizing equipment

The chemical filter screen sterilization and disinfection part adopted by the circulating air chemical filtering and disinfection equipment 3 is a multi-time sterilization and disinfection structure, as shown in fig. 3. The fan 31 is arranged on the top of the circulating air chemical filtering sterilizing device, and a chemical filter screen 32, an ultraviolet sterilizing bin 33 and a filter 34 are arranged below the fan. After the fan 31 is started, negative pressure is formed in the structure of the circulating air chemical filtering and sterilizing equipment, indoor air is sucked in and is blown out through the top fan after being filtered, and indoor air circulation is formed. The air quantity of the circulating air chemical filtering disinfecting and killing equipment is 972m³The speed of the fan is 60m in 10 minutes³The air circulation amount is approximately 3 times formed in the space.

Air in the space enters the product air duct from the bottom, dust with the diameter larger than PM2.5 in the air is filtered by the high-efficiency filter 34, dust removal and purification of the air are achieved, and virus and bacteria are attached to particles, so that the amount of intercepted dust is the reduction of the virus and the bacteria. The primary air dedusting and purifying further has the functions of keeping the subsequent device clean, prolonging the service life of the device and reducing the subsequent maintenance.

However, the pure air filtration bacterial virus reduction is only the initial stage of the filter, and the bacterial virus blocked on the filter can be propagated and copied on the filter along with the prolonging of the service time, so that the filter becomes a pollution source.

In the application, the defect that the 6W 254nm wavelength ultraviolet lamp tube is arranged in the interlayer space between the high-efficiency filter 34 and the chemical filter screen 32 to carry out primary sterilization and disinfection on the air passing through the high-efficiency filter 34 is avoided. The ultraviolet lamp tube has another function of exciting the activity of chemical substances on the chemical filter screen 32 and enhancing the sterilization and disinfection capability of the chemical filter screen.

The air is sterilized and disinfected by the chemical filter screen, and residual PM2.5 particles are removed, so that the air blown out by the fan does not contain viruses, bacteria and particles with the diameter larger than PM 2.5.

The fan 31 is a variable air volume fan, can circulate at a large air volume under full load, and can realize virus and bacteria in the chemical filter screen filtering chamber with lower air volume under a mute state.

After the product establishes innovative functional characteristics of thorough disinfection, quick disinfection and flexible combination, besides medical related places which need disinfection, a plurality of problems which disturb the society due to new coronavirus are solved, such as: conference rooms, office buildings, school classrooms, public service business halls, subway and airplane high-speed rails and the like can be efficiently killed in a short time before application. By adopting a circulating air chemical filtering and disinfecting mode, various bacteria and viruses generated by gathering of people can be killed and reduced, and a sterile and nontoxic sanitary environment is provided.

In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
