The casing that air cleaning box of the present invention 104 uses metals to make can also scribble the coating of leaded, bismuth or its combination on the tank surface.So, can effectively intercept the radiation that discharges with the absorbed air pollutant, such as α, β and gamma-rays etc.
Fig. 5 is the operation principle schematic diagram of the air cleaning unit 101 of another preferred embodiment of the present invention.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 for preventing, for example outdoor rainwater and larger object enter air cleaning box 104, cause damage.
Micro particle filtering layer 109 and gas filter course 110 are arranged in air cleaning box 104 near exhaust outlet 107 1 ends, the cylindrical hollow structure that formation arranges along air cleaning box 104 Air flow directions, and sealing near described 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 by 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 preliminary larger object of filtering particle enters air cleaning box 104.Enter the air to be clean of air cleaning box 104 at first through peroxide releasing unit 108.Oxide releasing unit 108 produces oxide connect electricity from the outside after, and the oxide that discharges or ion mix with the air to be clean of suction, are then taken to micro particle filtering layer and the gas filter course of cylinder type hollow structure by air-flow.Owing to columnar structuredly sealing near air inlet 106 1 ends, the gaseous oxygen compound that discharges or ion can and be taken to micro particle filtering layer 109 and the gas filter course 110 of barrel in the cylinder external diffusion by air-flow.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 adsorbing the radioactive substance of pernicious gas and gaseous state.Oxide or ion enter 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 (such as titanium, manganese, cobalt and palladium etc.) with catalytic activity, and under the catalytic action of transition metal material, pernicious gas is further oxided and decomposes.Finally, the air after purifying enters indoor from exhaust outlet 107.
Indoor positive pressure air cleaning device 101 of the present invention adopts effective integrated work principle of filter, and apparatus structure is simple, simple operation, simultaneously can be with a device high-efficient cleaning except multiple pollutant.By 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 present invention can be according to different environment, select the various combination of suitable oxide, micro particle filtering layer, gas filtration layer etc. and apply 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, and is indoor to prevent that it from entering.Micro particle filtering layer 109 can be efficiency particulate air screen pack (HEPA), primary efficient filter screen, electro static filtering net or its any combination.In the concrete practice, (such as particle species, size, concentration etc.) selects 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 to realize by both cooperations of micro particle filtering layer 109 and oxide releasing unit 108.At first bacterium and virus are filtered by micro particle filtering layer 109.The oxide (such as ozone and ion) that oxide releasing unit 108 discharges can and 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 the virus in the micro particle filtering layer, thereby can not cause secondary pollution.
For processing tool radioactive pollutant such as fall-out, can use to realize by the cooperation of micro particle filtering layer 109, gas filtration layer 110 and air cleaning box 104.Micro particle filtering layer 109 (such as HEPA) can filter dust and the particulate that contains radioactive substance (such as 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; The casing that air cleaning box 104 uses metals to make also scribbles the coating of leaded, bismuth or its combination on the tank surface, so, can effectively intercept and absorb the radiation (such as α, β and gamma-rays etc.) that air pollutants discharge; Final through after the described air cleaning unit 101, will not have radioactive substance and enter indoor.
For removing pernicious gas, then can use to realize by the cooperation of gas filtration layer 110 and oxide releasing unit 108.Gas filtration layer 110 can filter the pollutants such as industrial chemicals commonly used (as: positive methane, methyl alcohol, isopropyl alcohol, ammonia) of peculiar smell, formaldehyde, VOC (VOCs) even tool danger.Pernicious gas and the oxide that just discharged are together during gas coming through filter course 110, 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 effectively oxidation and decomposition of pernicious gas, generate harmless product, and can not cause secondary pollution.When catabolite (for example, carbon dioxide and water) by when the air-flow that purifies is taken away, filter material 112 will be regenerated, and further adsorbs pernicious gas and oxide.Have the adding of the transition metal (such as titanium, manganese, cobalt and palladium) of catalytic action, can strengthen decomposition rate and capacity of decomposition to 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, indoor positive pressure air cleaning device of the present invention 101 is simple in structure, easy to use, can prevent that outdoor pollutant from entering indoor; And can will introduce indoor formation cross-ventilation through the outdoor air that purifies; Can also in a device, purify simultaneously polytype pollutant.
