The specific embodiment
Then, embodiments of the present invention are described with reference to the accompanying drawings.
Fig. 1 is the diagrammatic illustration figure of the xegregating unit of present embodiment.In Fig. 1, label RA represents the isolation ward of xegregating unit.This isolation ward RA is than the little chamber of R volume, room that is provided with xegregating unit.This isolation ward RA forms combination such as the plate of Merlon system, possesses to be used for exhaust outlet Rb that extraneous gas is taken into the air entry Ra of inside and is used for the air of inside is discharged to the outside on its wall.And, isolation ward RA constitutes, make that extraneous gas can not invade the inside from the part beyond air entry Ra and the exhaust outlet Rb or inner air must lack to external leaks, in other words, remain the part beyond air entry Ra and the exhaust outlet Rb airtight or roughly airtight.
In isolation ward RA, be provided with for example polishing filter of HEPA filter or ulpa filter etc. at this air entry Ra, on this exhaust outlet Rb, connecting the attraction portion 3 of air cleaning unit 1 described later airtightly.The polishing filter of HEPA filter or ulpa filter etc. since air by the time resistance have about hundreds of Pa, so the difference of the air pressure inside and outside isolation ward RA hour, does not almost have the exchange of air between isolation ward RA inside and outside by air entry Ra.
Above-mentioned isolation ward RA volume inside RB is a so-called better purifying space in claims.
In addition, as long as the structure of isolation ward RA constitutes and the part beyond air entry Ra and the exhaust outlet Rb remained airtight or roughly airtight just passable, be not particularly limited.
In addition, the room R that isolation ward RA is set for example respectively in old man's welfare facility corresponding to each room if research facilities such as enterprise and university then corresponding to the custodial warehouse of research department or medicine if general dwelling house is then corresponding to being provided with in the R of space of each room etc., but be not particularly limited.In addition, isolation ward RA also can be provided with without.Particularly, also can on the plummer of truck etc., isolation ward RA and air cleaning unit described later 1 be set, can be in the disaster site easy and isolation ward RA promptly is provided when disaster etc. in the case, so be preferred.
As shown in Figure 1, on the exhaust outlet Rb of isolation ward RA, connecting the attraction portion 3 of air cleaning unit 1 airtightly, between this attraction portion 3 and exhaust outlet Rb, be equipped with and purify mechanism 12.Arranged in order with filter is caught from the exhaust outlet Rb bacterium etc. that the dedusting of bigger seizure dust etc. can also be caught bacterium etc. except dust etc. with filter, HEPA filter or half HEPA filter, ulpa filter etc. according to mesh successively towards attraction portion 3 by this purification mechanism 12.
In addition, purify mechanism 12 and be not limited to structure as described above, so long as it is just passable to cooperate employed environment to make only structure, the combination of filter also is not limited to combination as described above.
In addition, also the filter set with structure same with purifying mechanism 12 can be arranged among the exhaust outlet Rb of isolation ward RA, in the case, purification mechanism 12 can be set between attraction portion 3 and exhaust outlet Rb also.
As shown in Figure 1, the attraction portion 3 of air cleaning unit 1 possesses peristome and is connected cup 3a in the above-mentioned purification mechanism 12 and the airtight container 10 that is communicated with airtightly via pipe arrangement 3p and this cup 3a airtightly.
As shown in Figure 1, in the hollow space 10h of the inside of airtight container 10, outside hollow space 10h, be equipped with and attract mechanism 11 with airtight airtightly state.This attracts mechanism 11 to discharge from outlet 11b from the suction inlet 11a inhaled air of air blast etc., constitute, this attractions mouthful 11a with state that pipe arrangement 3p separates under open the interior air of attraction hollow space 10h to hollow space 10h.Therefore, if the air that attracts mechanism 11 to attract in the hollow space 10h, then the pressure in the hollow space 10h reduces, and pressure becomes than low in cup 3a and the isolation ward RA, so the air of isolation ward RA attracted in the hollow space 10h of airtight container 10 by cup 3a, pipe arrangement 3p.At this moment, owing to be provided with among the attraction mouth 11a that attracted to direct attraction mechanism 11, so can in hollow space 10h, form air-flow by the air in the hollow space 10h that is attracted to airtight container 10 from pipe arrangement 3p.The reason that forms air-flow in the hollow space 10h of airtight container 10 is narrated in the back.
In addition, an end that on the outlet 11b that attracts mechanism 11, is connecting pipe arrangement 4p airtightly.The other end of this pipe arrangement 4p with the outside of isolation ward RA, for example be provided with in the room R of isolation ward RA or discharge portion 4 connections that room R is communicated with outward.In addition, pipe arrangement 4p is connected airtightly with airtight container 10 certainly.
Owing to be above such structure, if attract mechanism's 11 actions so make, then the air in the isolation ward RA is discharged to the outside with discharge portion 4 quilts by pipe arrangement 4p by in the hollow space 10h of inside that purifies mechanism 12, cup 3a, pipe arrangement 3p and attracted to airtight container 10.And, owing to be discharged from air outside by purifying mechanism 12, even, also bacterium etc. is removed, so can prevent the bacterium space-pollution that isolation ward RA is outer that waits in the isolation ward RA by being present in by purifying mechanism 12 so in isolation ward RA, have bacterium etc.
And, isolation ward RA constitutes, part beyond air entry Ra and the exhaust outlet Rb is remained airtight or roughly airtight, if the air by attracting mechanism 11 to attract in the isolation ward RA, then in the isolation ward RA by attracting inner air to become air pressure than outside low state.That is,, can infect disease countermeasure chamber with being used as in the isolation ward RA owing to can make isolation ward RA become negative pressure chamber.And, attracted to air among the cup 3a of attraction portion 3 by exhaust outlet Rb necessarily by purifying mechanism 12, so in isolation ward RA, when infecting disease countermeasure chamber, can prevent that the bacterium that the patient discharged etc. in the isolation ward RA is discharged to the outside by air cleaning unit 1.
In addition, if the pressure in the isolation ward RA reduces then flow in the isolation ward RA by air entry Ra, but,, also can remain outer low pressure than isolation ward RA even leaked-in air flow in the isolation ward RA owing in air entry Ra, be provided with the bigger polishing filter of aeration resistance.
In addition, in discharge portion 4 or pipe arrangement 4p, also can be provided with and possess for example heating arrangements 4d of heater for heating air such as heater or combustion furnace, in the case, will be through the air of pipe arrangement 4p etc. owing to can heat by heating arrangements 4d, even so just in case whether be cleaned bacterium that mechanism 12 catches or virus etc., as long as heat resistances such as this bacterium or virus are relatively poor, also can kill by heating arrangements 4d.Particularly, if by heating arrangements 4d with more than the air heat to 100 ℃ then can be, if be heated to again more than 300 ℃ then can sterilize reliably with air sterilization.Particularly, if heating arrangements 4d possesses the heating part again that hot-air heats once more that adds by the heating arrangements heating, then can further improve sterilizations such as bacterium or virus, sterilization effects.As this heating part again, can adopt the heating part of the structure of resistance parts such as in the stream of air configuration honeycomb or punched-plate, pottery, sword mountain type, wire netting.If such resistance parts make its temperature become than the temperature height that adds hot-air that flows to the resistance position component by the heat of above-mentioned heater or the heat of the special heater that is provided with etc., then can heat again adding hot-air.And, in heating part again, add flowing of hot-air owing to hindered, so can prolong again the holdup time that adds hot-air of heating part by the resistance parts.In other words, owing to can prolong the heat time heating time that adds hot-air that the resistance parts carry out, so can further improve to sterilizations such as bacterium or virus, sterilization effects.Particularly, if as honeycomb etc., use the bigger resistance parts of surface area, then can increase the touch opportunity that adds hot-air and resistance parts, can make the time of contact that adds hot-air and resistance parts also further elongated, so can further improve to sterilizations such as bacterium or virus, sterilization effects.
In addition, also can with heating arrangements or replace heating arrangements and bactericidal lamp is set or by medicament etc. to the sterilizing unit of sterilizations such as bacterium etc., in the case, also can be with sterilization, sterilizations such as airborne bacterium or viruses.
And then, also can not be provided with and purify mechanism 12 and above-mentioned heating arrangements 4d only is set, can prevent more reliably that the bacterium etc. in the isolation ward RA from discharging to the outside but possess both.
In addition, attract mechanism 11 to be enclosed in airtightly in the hollow space 10h of airtight container 10, it attracts mouthful 11a open in hollow space 10h, but because outlet 11b is connected airtightly with pipe arrangement 4p in hollow space 10h, even so from attracting mechanism 11 that leakage of air is arranged, also the air of this leakage can be remained in the hollow space 10h, and then from attracting mouthful 11a to attract.That is, because can be from air cleaning unit 1 to external leaks, so can prevent by the air that leaks from attraction mechanism 11 with the space-pollution outside the isolation ward RA from the air that attracts mechanism 11 to leak.
For example, under the situation that might in isolation ward RA, have the bacterium that can not catch by purification mechanism 12, if the not shown treating apparatus can handle this bacterium etc. is set in xegregating unit, for example with the pasteurization device with the same function of above-mentioned heating arrangements 4d of having of bacterium pasteurization, or by the processing mechanisms such as sterilizing unit with sterilizations such as bacteriums such as medicament, air is supplied to this processing mechanism from discharge portion 4, even then just in case exist in air can not be by purifying bacterium that mechanism 12 catches etc., also can be with this bacterium sterilization, but in this case, make during air is transplanted on treating apparatus in the isolation ward RA, need air can not leak into structure in the outer space of isolation ward RA fully.In this case, if attract mechanism 11 to be enclosed in airtightly among the hollow space 10h of airtight container 10, even then air leaks from attracting mechanism 11, the air that leaks also is maintained in the hollow space 10h, so can prevent by the air that leaks from attraction mechanism 11 air pollution outside the isolation ward RA.
In addition, if make structure as described above, then both can be arranged on than attracting mechanism 11 to lean on upstream side, in other words be arranged on, also can be arranged on than attracting mechanism 11 to lean on the downstream, in other words be arranged on purifying mechanism 12 than attracting mechanism 11 by discharge portion 4 sides with purifying mechanism 12 than attracting mechanism 11 by isolation ward RA side.So, can improve the in-built free degree of air cleaning unit 1.
And, if make air cleaning unit 1 action of present embodiment, then the air cleanliness in the isolation ward RA can be remained 10, more than 000 grade (can remain on the specification 209E of the United States Federal (if JIS-B-9920 then is 7 grades)), if the air-tightness in the isolation ward RA improves, then can remain 1,000 grade (the specification 209E of the United States Federal (if JIS-B-9920 then is 6 grades)) above, approach the cleannes of 100 grades (the specification 209E of the United States Federal (if JIS-B-9920 then is 5 grades)).In addition, for the living environment in the isolation ward RA being remained comfortable state and in isolation ward RA, being provided with under the situation of air-conditioning equipment, if this air-conditioning equipment is moved then the cleannes reduction, but also can keep 1,000 grade (the specification 209E of the United States Federal (if JIS-B-9920 then is 6 grades)) above cleannes in the case.
In addition, owing to attract mechanism 11 to be sealed in the hollow space 10h of airtight container 10, so even will attract mechanism 11 to maximize also can to prevent the deterioration of the indoor environment brought by the noise that attraction mechanism 11 sends.The large-scale mechanism with the above attraction of tens kPa for example, and compares, even also can use in the general indoor mechanism that has only the attraction about hundreds of Pa that uses in the air cleaning unit of type that is provided with.And, attract the attraction mouth 11a of mechanism 11 to separate by making with pipe arrangement 3p, can reduce the pressure loss, the noise that produces in the time of can reducing from the hollow space 10h of airtight container 10, to suck air by the attraction mouth 11a generation that attracts mechanism 11.And then, attract the attraction mouth 11a of mechanism 11 to separate by making with pipe arrangement 3p, can freely design caliber and the radical of the pipe arrangement 3p that is communicated with in the hollow space 10h with cup 3a and airtight container 10, so also can make the sectional area of hollow space 10h of the sectional area of sectional area ratio cup 3a of each pipe arrangement 3p and airtight container 10 little.So, can reduce the noise that produces when flowing into air 10 from cup 3a to airtight container.
And then, if the heat that attracts mechanism 11 to maximize then attract mechanism 11 to produce is also increased, so, then become problem because of the fault of cooling off the bad attraction mechanism 11 that causes if be sealed in the hollow space 10h of airtight container 10.But, under the situation of the air cleaning unit 1 of present embodiment, owing in the hollow space 10h of airtight container 10, form air-flow, to attract mechanism's 11 coolings by this air-flow, even, attract mechanism 11 also can Yin Wendu to rise and damage so attract mechanism 11 to be sealed in the hollow space 10h of airtight container 10.
Above-mentioned pipe arrangement 3p, airtight container 10, to attract mechanism 11 and pipe arrangement 4p be so-called displace air mechanism in the technical scheme book, and pipe arrangement 3p is a so-called intake channel in the technical scheme book, and pipe arrangement 4p is a so-called exhaust channel in the technical scheme book.
In addition, in above-mentioned xegregating unit, constitute the air entry Ra of ambient atmos from isolation ward RA imported in the isolation ward RA, make from attracting the part of air that mechanism 11 supplies with or all get back to peripheral passage 4c in the isolation ward RA if the ventilation path 3c that the hollow space 10h of airtight container 10 is communicated with space outside the isolation ward RA is set in suction unit 3 and in discharge portion 4, is provided with, then can be with ambient atmos with importing in the isolation ward RA by purifying the air that mechanism 12 purified.So, because it is also passable that the air entry Ra of isolation ward RA is not set, so can further improve the air-tightness of isolation ward RA.
And, if the flow regulator Fc of the amount of regulating the air that flows through peripheral passage 4c is set in the 4c of peripheral passage, in other words the flow regulator Fc that regulates the amount of getting back to the air in the isolation ward RA is set, make from the part of air that attracts mechanism 11 to supply with, particularly make from the air that attracts mechanism 11 to supply with and get back in the isolation ward RA, so that the quantitative change of getting back in the isolation ward RA from peripheral passage 4c must be lacked than the amount of the air that attracts in isolation ward RA, when then can also in isolation ward RA, remain negative pressure, will take a breath in the isolation ward RA by the outer gas the hollow space 10h that imports to airtight container 10 from ventilation path 3c.
In addition, if make from attract air that mechanism 11 supplies with all or part of, particularly make from the air that attracts mechanism 11 to supply with and get back in the isolation ward RA, so that the quantitative change of getting back in the isolation ward RA from peripheral passage 4c must be more than the amount of the air that attracts in isolation ward RA, then can will remain malleation in the isolation ward RA, thus can with in the isolation ward RA as desinfection chamber.In the case, invade in the isolation ward RA in order to prevent to be included in assorted bacterium in the ambient atmos etc., ventilation path 3c and peripheral passage 4c both or the mechanism that has with the same air cleaning ability of purification mechanism 12 is set in any.
In addition, be under the situation of malleation in making isolation ward RA, need and the air in the isolation ward RA can be discharged to the outside, if and make isolation ward RA as described above with air entry Ra, then both the air in the isolation ward RA can be discharged to the outside from air entry Ra, air outside can be attracted in the isolation ward RA from air entry Ra again, can both use so in making isolation ward RA, become under any situation of malleation or negative pressure, so be preferred.
