The air cleaning box 104 of the utility model uses the casing of made, can also scribble the coating of leaded, bismuth or its combination on the tank surface.So, can intercept the radiation that is discharged with the absorbed air pollutant effectively, like α, β and gamma-rays etc.
Fig. 5 is the operation principle sketch map of the air cleaning unit 101 of another preferred embodiment of the utility model.As shown in the figure, air filter 101 comprises air cleaning box 104 and blower fan 105.Blower fan 105 is arranged on outside the air cleaning box 104, and is connected with exhaust outlet 107.Air inlet 106 1 ends in the air cleaning box 104 also are provided with water proof face shield 117 and primary efficient filter screen 118, are used to prevent, for example outdoor rainwater and bigger object get into air cleaning box 104, cause damage.
Micro particle filtering layer 109 is arranged in air cleaning box 104 near exhaust outlet 107 1 ends with gas filter course 110; The cylindrical hollow structure that formation is provided with along air cleaning box 104 air flow directions; And sealing near said air inlet 106 1 ends; Wherein micro particle filtering layer 109 forms the outer wall of cylinder side wall, and gas filtration layer 110 forms the inwall of cylinder side wall.Oxide releasing unit 108 is arranged on the end of columnar structured sealing, and is connected to the external control unit through connecting line 119.
Air direction shown in the dotted arrow in Fig. 5 flows.Blower fan 105 is with outdoor contaminated air suction air cleaning box 104, and water proof face shield 117 and primary efficient filter screen 118 at air inlet 106 places can at first intercept moisture, and the bigger object of preliminary filtering particle gets into air cleaning box 104.The air to be clean that gets into air cleaning box 104 is at first through peroxide releasing unit 108.Oxide releasing unit 108 connects the electricity back and produces oxide from the outside, oxide that discharges or ion mix with the air to be clean of suction, are taken to the micro particle filtering layer and the gas filter course of cylinder type hollow structure then by air-flow.Sealing near air inlet 106 1 ends owing to columnar structured, gaseous oxidation thing that discharges or ion can take the micro particle filtering layer 109 and gas filter course 110 of barrel in the tube external diffusion and by air-flow to.Micro particle filtering layer 109 can be efficiency particulate air screen pack (HEPA), is used for filter particulates, bacterium, virus and fall-out.Filter material 112 in the gas filtration layer 110 can be to be zeolite, is used for the radioactive substance of absorption pernicious gas and gaseous state.Oxide or ion get into the duct of gas filtration layer 110 with pernicious gas, and are attracted on the filter material 112.Filter material 112 can comprise the transition metal material (like titanium, manganese, cobalt and palladium etc.) with catalytic activity, and under the catalytic action of transition metal material, pernicious gas is by further oxidation and decomposition.Finally, enter indoor through cleaned air passes from exhaust outlet 107.
The indoor positive pressure air purifier 101 of the utility model adopts effective integrated work principle of filter, and apparatus structure is simple, simple operation, can use a device efficiently to remove multiple pollutant simultaneously.Through cooperatively interacting between oxide releasing unit 108, micro particle filtering layer 109, gas filtration layer 110 and the metal cabinet; Effectively remove dissimilar high-risk air pollutants; Comprise high-concentration particle, germ, fall-out and pernicious gas etc., with the protection health.The utility model can be according to different environment, selects the various combination of suitable oxide, micro particle filtering layer, gas filtration layer etc. and applies in a flexible way, to reach maximum purification efficiency.
At first for removing high-concentration particle (comprising grit and pollen), micro particle filtering layer 109 can filter them, to prevent in its inlet chamber.Micro particle filtering layer 109 can be efficiency particulate air screen pack (HEPA), primary efficient filter screen, electro static filtering net or its combination in any.In the concrete practice, (for example particle species, size, concentration etc.) are selected different micro particle filtering layers 109 according to actual needs, or their combination reaches the optimum filtration effect.
For aerial bacterium and the virus of remove floating, can use through both cooperations of micro particle filtering layer 109 and oxide releasing unit 108 and realize.At first bacterium is filtered by micro particle filtering layer 109 with virus.The oxide (like ozone and ion) that oxide releasing unit 108 discharges can with the air-flow mixing, can effectively eliminate or the inactivation air-flow in bacterium and virus.In addition, oxide can also pass through micro particle filtering layer 109 with air-flow, and under the effect of oxide, further elimination or inactivation are adsorbed on bacterium and virus in the micro particle filtering layer, thereby can not cause secondary pollution.
For handling tool radioactive pollutant such as fall-out, can use through the cooperation of micro particle filtering layer 109, gas filtration layer 110 and air cleaning box 104 and realize.Micro particle filtering layer 109 (like HEPA) can filter dust and the particulate that contains radioactive substance (like caesium and uranium) effectively; The radioactive substance of gaseous state such as radon gas then can be adsorbed in the filter material 112 of special pore size distribution; Air cleaning box 104 uses the casing of made, also scribbles the coating of leaded, bismuth or its combination on the tank surface, so, can intercept and absorb the radiation (like α, β and gamma-rays etc.) that air pollutants discharge effectively; Final through after the said air cleaning unit 101, will not have in the radioactive substance inlet chamber.
For removing pernicious gas, then can use and realize through the cooperation of gas filtration layer 110 and oxide releasing unit 108.Gas filtration layer 110 can filter the dangerous industrial chemicals commonly used of peculiar smell, formaldehyde, VOC (VOCs) even tool pollutants such as (as: positive methane, methyl alcohol, isopropyl alcohol, ammonia).Pernicious gas is during with the oxide that has just discharged gas coming through filter course 110 together; Can be adsorbed on together in the duct of filter material 112; As indicated above, under the catalytic activity transition metal material effect that in filter material 112, contains, oxide can be with pernicious gas oxidation and decomposition effectively; Generate harmless product, and can not cause secondary pollution.When catabolite (for example, carbon dioxide and water) by through the carried away by air movement that purifies the time, filter material 112 will be regenerated, and comes further absorption pernicious gas and oxide.Have the adding of the transition metal (like titanium, manganese, cobalt and palladium) of catalytic action, can strengthen decomposition rate and capacity of decomposition gaseous contaminant.Simultaneously, filter material 112 can also effectively decompose residual oxide, is discharged into outside the air cleaning unit 101 to prevent it.
To sum up, the indoor positive pressure air purifier 101 of the utility model is simple in structure, easy to use, can prevent in the outdoor pollutant inlet chamber; And can be with introducing indoor formation cross-ventilation through the outdoor air that purifies; Can also in a device, purify polytype pollutant simultaneously.
