Description
Technical field
This utility model relates to the device that a kind of gas that central air-conditioning is sent carries out disinfection and purifies.
Background technology
Since atypical pneumonia was popular, each side (comprising hospital, public place, subway, office, market etc.) greatly increased the demand of air sterillization.Existing air disinfection method mainly is peracetic acid mist fumigation and steaming method and uviol lamp sterilization.With peracetic acid mist fumigation and steaming method sterilization equipment there is serious corrosivity, people's eyes, respiratory tract had serious stimulation; The people can not be at the scene when sterilizing with uviol lamp, and use is restricted.Additive method because sterilizing efficiency is lower, can not reach the on-the-spot disinfectant sanitary standard of hospital of GB15982-1995.The gas that central air-conditioning is carried has also been made some new regulations during this period, and existing each side is badly in need of having no side effect air sterilization technique that sterilization effect is good and equipment.
In the air sterillization scheme device of existing part central air-conditioning, the gas of central air-conditioning being sent by drainage screen filters, gas after the filtration is sent to each unitary user through ultraviolet light source, catalysis net, shutter, because windage is big, cold air is difficult for flowing, cause the thermoregulation weak effect, sterilization rate is low.
Summary of the invention
In order to overcome the defective of said apparatus, the utility model proposes a kind of air sterillization sterilization, the device that has the function of catalytic degradation organic pollutant simultaneously to the central air-conditioning circulating current.This device can have good sterilization and reduce the air disinfection and purification function of organic contamination substrate concentration in the room air under the condition of low windage.
A kind of air disinfecting and purifying device of the present utility model, comprise housing, drainage screen, light source, shutter, it also comprises the nano-photo catalytic degradable material, drainage screen, uviol lamp and shutter are installed on the housing successively, drainage screen is installed in the air inlet place of housing, shutter is installed in the air outlet place of housing, and uviol lamp is installed between drainage screen and the shutter, is mounted with the nano-photo catalytic degradable material on the shutter.
Described air disinfecting and purifying device, the barrier board of its shutter are the knuckle shape, and the nano-photo catalytic degradable material is loaded in the surface of barrier board.
Described air disinfecting and purifying device, the barrier board knuckle angle of its shutter are 30～150 degree, and the mounting distance of barrier board and barrier board is 5～30 millimeters.
Described air disinfecting and purifying device, its nano-photo catalytic degradable material is for containing nano-TiO
2Catalysis material, its TiO
2Particulate size is less than 30 nanometers.
Air disinfecting and purifying device of the present utility model under the little situation of windage, can effectively go out except that the antibacterial in the organic pollutant, and this apparatus structure is reasonable in design, and cost is low.This device has been realized the air sterillization sterilization to the circulating current of central air-conditioning, simultaneously circulating current is carried out catalytic degradation and reaches air sterillization and the purpose that reduces organic pollution in the elimination room air in the room.The design of shutter barrier board knuckle shape has avoided ultraviolet directly to penetrate from shutter simultaneously, causes the injury of ray.

Fig. 3 is the structure cutaway view of existing shutter barrier board.
Among the figure: 1. housing 2. drainage screens 3. uviol lamps 4. shutters 5. nano-photo catalytic degradable materials 6. airflow directions 7. ultraviolet directions 8. installed parts 9. uviol lamps 10. shutters 11. uviol lamps 12. shutters 13. ultraviolet directions
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
See also shown in Figure 1, a kind of air disinfecting and purifying device of the present utility model, form by housing 1, drainage screen 2, uviol lamp 3, shutter 4, nano-photo catalytic degradable material 5, drainage screen 2, uviol lamp 3 and shutter 4 are fixed on the housing 1 successively, drainage screen 2 is installed in the air inlet place of housing 1, shutter 4 is installed in the air outlet place of housing 1, and uviol lamp 3 is installed between drainage screen 2 and the shutter 4, is mounted with nano-photo catalytic degradable material 5 on the shutter 4.
Quite a lot of for the quality that makes the gas that central air-conditioning transfers out, also can establish a plurality of uviol lamps, shutter, realize multiple sterilizing and purifying.See also shown in Figure 2ly, be provided with installed part 8 in housing 1, shutter 10 is installed on the installed part 8, near uviol lamp 9 is installed near the barrier board of shutter 10, also is mounted with nano-photo catalytic degradable material 5 on the shutter 10 simultaneously.
Sterilizing and purifying device of the present utility model, the barrier board of its shutter 4,10 is that (inventor is designed to the knuckle shape to the knuckle shape, be to touch nano-photo catalytic degradable material 5 in order to allow air-flow collide better, and under uviol lamp 3,9 irradiations, realize air disinfection and purification, can prevent simultaneously ultraviolet) to the air outlet external leakage, nano-photo catalytic degradable material 5 is loaded in the surface (its load mode can be coating, also can be paster) of barrier board.The barrier board knuckle angle of shutter 4,10 is 30～150 degree, and the barrier board of shutter 4,10 and the mounting distance of barrier board are 5～30 millimeters.The angle of barrier board knuckle is relevant with the mounting distance of barrier board and barrier board, and the fabrication and processing standard can not direct projection go out to be advisable from shutter 4,10 with the ultraviolet light of uviol lamp 3,9.
See also shown in Figure 3ly, the barrier board of existing shutter 12 is a parallel shape, and this structure easily causes ultraviolet light 13 directly to penetrate from shutter 12, and human body is damaged.
Sterilizing and purifying device of the present utility model, its uviol lamp 3,9 required power supplys can be separate cabling, independent control; Also can with the switch interlock of central air-conditioning, or set up an independent switch.
Sterilizing and purifying device of the present utility model can be arranged separately in the air outlet or the return air inlet place of each house lead in of central air-conditioning with it by the installed part that is located on the housing 1; Also can be installed in the air cleaning system of central air conditioner main machine, or be installed in the central air-conditioning gas pipeline, during installation, only need this device is got final product with the channel seal of central air-conditioning is fixing.
In experiment, the inventor utilizes homemade model machine, has carried out on-the-spot air sterilization experiment in hospital, and room area is 12m
2(volume is 40m
3), the result is as follows in sterilization:
| Number of times | Bacterium amount (cfu/m before the sterilization 3) | 30 minutes bacterium amount (cfu/m sterilize 3) | Extinction rate (%) | 60 minutes bacterium amount (cfu/m sterilize 3) | Extinction rate (%) |
| 1 | 3000 | 150 | 95 | - | - |
| 2 | 4000 | 300 | 93 | 50 | 99 |
| 3 | 2400 | 250 | 90 | - | - |
Experimental result shows that at the indoor effect observation that carries out disinfection under the unmanned situation of closing, sterilization rate reached average sterilization rate 〉=90% 95%, 93%, 90%, three time in 30 minutes.
