1 Ka hoʻāʻo ʻana i ke ʻano hoʻāʻo
Nui nā ʻano no ka ʻike ʻana i nā kānana ea HEPA, a he ʻokoʻa nā kūlana o nā ʻāina like ʻole. I ka makahiki 1956, ua hoʻomohala ke Komisina Koa o ʻAmelika i ka USMIL-STD282, kahi maʻamau hoʻāʻo kānana ea HEPA, a me ke ʻano DOP no ka hoʻāʻo ʻana. I ka makahiki 1965, ua hoʻokumu ʻia ke kūlana Pelekane ʻo BS3928, a ua hoʻohana ʻia ke ʻano ahi sodium no ka ʻike pono. I ka makahiki 1973, ua hoʻomohala ka European Ventilation Association i ka Eurovent 4/4 maʻamau, e hahai ana i ke ʻano o ka ʻike ʻana i ke ahi sodium. Ma hope mai, ua hōʻuluʻulu ka American Society for Environmental Testing and Filter Efficiency Science i ke ʻano o nā kūlana like no nā ʻano hana hoʻāʻo i manaʻo ʻia, me ka hoʻohana ʻana i ke ʻano helu DOP caliper. I ka makahiki 1999, ua hoʻokumu ʻo ʻEulopa i ka maʻamau BSEN1822, ka mea e hoʻohana ana i ka nui o ka nui o nā ʻāpana kikoʻī (MPPS) e ʻike i ka pono kānana [4]. Hoʻohana ke kūlana ʻike o Kina i ke ʻano o ka lapalapa sodium. Hoʻokumu ʻia ka ʻōnaehana ʻike hoʻokō o ka kānana ea HEPA i hoʻohana ʻia ma kēia hoʻokolohua ma muli o ka maʻamau US 52.2. Hoʻohana ke ʻano ʻike i ke ʻano helu caliper, a hoʻohana ka aerosol i nā ʻāpana PAO.
1. 1 mea hana nui
Ke hoʻohana nei kēia hoʻokolohua i ʻelua mau helu kikoʻī, maʻalahi, maʻalahi, wikiwiki a intuitive i hoʻohālikelike ʻia me nā mea hana hoʻāʻo ʻokoʻa ʻē aʻe [5]. ʻO nā mea maikaʻi o luna o ka pākuʻi particle e hoʻololi mālie i nā ʻano hana ʻē aʻe a lilo i kumu hoʻāʻo nui no ka ʻike ʻana o ka particle. Hiki iā lākou ke helu i ka helu o nā ʻāpana a me ka puʻunaue ʻana o ka nui o nā ʻāpana (ʻo ia hoʻi, helu helu), ʻo ia ka mea nui o kēia hoʻokolohua. ʻO 28.6 LPM ka helu kahe o ka laʻana, a ʻo kāna pahu pahu pahu kalapona ʻole nā ​​hiʻohiʻona o ka haʻahaʻa haʻahaʻa a me ka hana paʻa. Inā hoʻokomoʻia ka koho, hiki ke anaʻia ka mahana a me ka haʻahaʻa a me ka makani makani a hiki ke ho'āʻoʻia ka kānana.
Hoʻohana ka ʻōnaehana ʻike i nā aerosol me ka hoʻohana ʻana i nā ʻāpana PAO e like me ka lepo e kānana ʻia. Hoʻohana mākou i nā mea hana aerosol (Aerosol generations) o ke kumu hoʻohālike TDA-5B i hana ʻia ma ʻAmelika Hui Pū ʻIa. ʻO ka laulā o ka hanana he 500 - 65000 cfm (1 cfm = 28.6 LPM), a he 100 μg / L, 6500 cfm; 10 μg / L, 65000 cfm.
1. 2 lumi maemae
I mea e hoʻomaikaʻi ai i ka pololei o ka hoʻokolohua, ua hoʻolālā ʻia a hoʻonani ʻia ka hale hana 10,000-level e like me ka US Federal Standard 209C. Hoʻohana ʻia ka papahele uhi, kahi i hōʻike ʻia e nā mea maikaʻi o terrazzo, ʻaʻahu i ke kūpaʻa, hoʻopaʻa maikaʻi, hoʻololi a me ka hana paʻakikī. ʻO ka mea he epoxy lacquer a ua hana ʻia ka paia me nā ʻāpana lumi maʻemaʻe i hui ʻia. Hoʻolako ʻia ka lumi me 220v, 2 × 40w hoʻomaʻemaʻe 6 mau kukui a hoʻonohonoho ʻia e like me nā koi o ka hoʻomālamalama a me nā lako kahua. ʻO ka lumi maʻemaʻe he 4 puka makani ma luna a he 4 puka hoʻihoʻi ea. Hoʻolālā ʻia ka lumi ʻauʻau ea no ka mana hoʻopā maʻamau hoʻokahi. ʻO 0-100s ka manawa ʻauʻau, a ʻoi aku ka nui o ka makani makani o kēlā me kēia nozzle leo ea hiki ke hoʻololi ʻia ma mua o 20ms. No ka mea he <50m2 ka lumi maʻemaʻe a ʻo nā limahana he <5 poʻe, hāʻawi ʻia kahi puka palekana no ka lumi maʻemaʻe. ʻO ka kānana HEPA i koho ʻia ʻo GB01 × 4, ʻo ka nui o ka ea he 1000m3/h, a ʻoi aku ka maikaʻi o ka kānana ma mua a i ʻole like me 0.5μm a me 99.995%.
1. 3 hōʻailona hoʻokolohua
ʻO nā hiʻohiʻona o ka kānana fiber aniani: 610 (L) × 610 (H) × 150 (W) mm, baffle type, 75 wrinkles, nui 610 (L) × 610 (H) × 90 (W) Mm, me 200 pleats, PTFE kānana nui 480 (L) (W) × 480 mm, me ka nui ʻole o ka kānana PTFE 480 (L) (L) × 480 mm. 100 wrinkles.
2 Nā loina kumu
ʻO ke kumu kumu o ka papa hoʻāʻo ʻo ia ka puhi ʻana o ka peʻahi i ka lewa. No ka mea ua lako pū ka HEPA/UEPA me kahi kānana ea HEPA, hiki ke noʻonoʻo ʻia ua lilo ka ea i ea maʻemaʻe ma mua o ka hiki ʻana i ka HEPA/UEPA i hoʻāʻo ʻia. Hoʻokuʻu ka mea hana i nā ʻāpana PAO i loko o ka pipeline e hana i kahi manaʻo i makemake ʻia o ke kinoea i loko o ka lepo a hoʻohana i kahi counter particle laser no ka hoʻoholo ʻana i ka manaʻo o ka particle. A laila, kahe ke kinoea i loko o ka lepo ma ka HEPA/UEPA i ho'āʻo ʻia, a ua ana pū ʻia ka neʻe ʻana o ka lepo i loko o ka ea i kānana ʻia e HEPA/UEPA me ka hoʻohana ʻana i ka counter particle laser, a ua hoʻohālikelike ʻia ka lepo lepo o ka lewa ma mua a ma hope o ka kānana, a laila e hoʻoholo ai i ka HEPA/UEPA. Hana kānana. Eia kekahi, ua hoʻonohonoho ʻia nā lua laʻana ma mua a ma hope o ka kānana, a ua hoʻāʻo ʻia ke kūʻē ʻana o kēlā me kēia makani makani ma o ka hoʻohana ʻana i kahi anana kaomi micro tilt ma aneʻi.

3 kānana hoʻohālikelike hana hoʻohālikelike
ʻO ka hiʻohiʻona kū'ē o HEPA kekahi o nā hiʻohiʻona nui o ka HEPA. Ma lalo o ka manaʻo o ka hālāwaiʻana i ka pono o ka noi o nā kānaka, pili nāʻano kū'ē i ke kumukūʻai o ka hoʻohanaʻana, heʻuʻuku ke kū'ē, he liʻiliʻi ka ikehu, a mālamaʻia ke kumukūʻai. No laila, ua lilo ka hana kū'ē o ka kānana i mea hopohopo. ʻO kekahi o nā hōʻailona koʻikoʻi.
Wahi a ka ʻikepili ana hoʻokolohua, loaʻa ka pilina ma waena o ka māmā makani maʻamau o nā kānana hoʻolālā like ʻole o ke aniani aniani a me ka kānana PTFE a me ka ʻokoʻa kaomi kānana.Hōʻike ʻia ka pilina ma ke Kiʻi 2:

Hiki ke ʻike ʻia mai ka ʻikepili hoʻokolohua e like me ka piʻi ʻana o ka makani, piʻi ke kūʻē o ka kānana ma ka laina laina mai ka haʻahaʻa a i ke kiʻekiʻe, a ʻo nā laina pololei ʻelua o nā kānana ʻelua o ke aniani aniani e kū like. He mea maʻalahi ke ʻike i ka wā o ka filtration wind speed he 1 m / s, ʻo ke kūpaʻa ʻana o ka kānana fiber aniani ma kahi o ʻehā mau manawa o ka kānana PTFE.

Ma ka ʻike ʻana i ka ʻāpana o ka kānana, hiki ke loaʻa ka pilina ma waena o ka wikiwiki o ke alo a me ka ʻokoʻa o ke kaomi kānana:
Hiki ke ʻike ʻia mai ka ʻikepili hoʻokolohua e like me ka piʻi ʻana o ka makani, piʻi ke kūʻē o ka kānana ma ka laina laina mai ka haʻahaʻa a i ke kiʻekiʻe, a ʻo nā laina pololei ʻelua o nā kānana ʻelua o ke aniani aniani e kū like. He mea maʻalahi ke ʻike i ka wā ʻo 1 m / s ka wikiwiki o ka makani kānana, ʻo ke kūpaʻa ʻana o ka kānana fiber aniani he ʻehā mau manawa o ka PTFE kānana.

Ma ka ʻike ʻana i ka ʻāpana o ka kānana, hiki ke loaʻa ka pilina ma waena o ka wikiwiki o ke alo a me ka ʻokoʻa o ke kaomi kānana:

Ma muli o ka ʻokoʻa ma waena o ka wikiwiki o ka ʻili o nā ʻano kānana kānana ʻelua a me ka ʻokoʻa o ke kaomi kānana o nā pepa kānana ʻelua, ʻoi aku ka kiʻekiʻe o ke kūpaʻa o ka kānana me ka kikoʻī o 610 × 610 × 90mm ma ka wikiwiki o ka ʻili like ma mua o ka kikoʻī 610 ×. Kū'ē o ka kānana 610 x 150mm.

Eia nō naʻe, ua maopopo ma ka wikiwiki o ka ili like, ʻoi aku ka kiʻekiʻe o ke kū'ē o ka kānana fiber aniani ma mua o ke kū'ē o ka PTFE. Hōʻike ia he ʻoi aku ka maikaʻi o ka PTFE ma mua o ke kānana fiber glass ma ke ʻano o ka hana kūʻē. I mea e hoʻomaopopo hou aku ai i nā ʻano o ka kānana fiber glass a me ke kūpaʻa PTFE, ua hoʻokō ʻia nā hoʻokolohua hou aʻe. E noʻonoʻo pono i ke kūʻē ʻana o nā pepa kānana ʻelua i ka loli ʻana o ka makani kānana, hōʻike ʻia nā hopena hoʻokolohua ma lalo nei.

Hōʻoia hou kēia i ka hopena mua i ʻoi aku ka kiʻekiʻe o ke kūpaʻa o ka pepa kānana fiber glass ma mua o ka PTFE ma lalo o ka wikiwiki makani like [6].
4 kānana kānana hoʻohālikelike hana
E like me nā kūlana hoʻokolohua, hiki ke ana ʻia ka pono kānana o ka kānana no nā ʻāpana me ka nui o 0.3 μm, 0.5 μm, a me 1.0 μm ma nā ʻano makani makani ʻokoʻa, a loaʻa ka pakuhi aʻe:

ʻIke loa, ʻo ka filtration efficiency o nā kānana fiber glass ʻelua no 1.0 μm particle ma nā ʻano makani makani ʻokoʻa he 100%, a ke emi nei ka filtration efficiency o 0.3 μm a me 0.5 μm me ka piʻi ʻana o ka wikiwiki o ka makani. Hiki keʻikeʻia heʻoi aku ka kiʻekiʻe o ka pono kānana o ka kānana i nā mea nui ma mua o nā'āpana liʻiliʻi, aʻo ka hana kānana o ka 610 × 610 × 150 mm kānana iʻoi aku ka maikaʻi ma mua o ka kānana o ka kiko'ī 610 × 610 × 90 mm.
Ke hoʻohana nei i ke ʻano like, loaʻa kahi pakuhi e hōʻike ana i ka pilina ma waena o ka pono kānana o ka kānana PTFE 480 × 480 × 70 mm ma ke ʻano he hana o ka wikiwiki o ka makani.

Ke hoʻohālikelike nei i ka Fig. 5 a me ka Fig. 6, ʻoi aku ka maikaʻi o ka hopena kānana o ka kānana aniani 0.3 μm, 0.5 μm, ʻoi aku ka maikaʻi no ka hopena o ka lepo 0.3 μm. ʻO ka hopena kānana o nā ʻāpana ʻekolu ma nā ʻāpana 1 μm he 100%.
I mea e oi intuitively hoohalike ai i ka filtration hana o ke aniani puluniu kānana a me ka PTFE kānana mea, nā kānana hana ho'āʻo i pololei hana ma luna o na pepa kānana elua, a ua loaa ka palapala ma lalo:

Loaʻa ka pakuhi ma luna ma ke ana ʻana i ka hopena kānana o PTFE a me ka pepa kānana fiber glass ma nā ʻāpana 0.3 μm ma nā ʻano makani ʻokoʻa [7-8]. ʻIke ʻia ʻoi aku ka haʻahaʻa o ka pono kānana o ka pepa kānana PTFE ma mua o ka pepa kānana aniani.
Ma ka noʻonoʻo ʻana i nā waiwai kū'ē a me nā waiwai kānana o ka mea kānana, he mea maʻalahi ke ʻike ʻoi aku ka kūpono o ka mea kānana PTFE no ka hana ʻana i nā kānana koʻikoʻi a i ʻole sub-HEPA, a ʻoi aku ka maikaʻi o ke aniani fiber filter no ka hana ʻana i nā kānana HEPA a i ʻole ultra-HEPA.
5 Ka hopena
ʻIke ʻia nā manaʻo no nā noi kānana like ʻole ma ka hoʻohālikelike ʻana i nā waiwai kū'ē a me nā waiwai kānana o nā kānana PTFE me nā kānana fiber glass. Mai ka hoʻokolohua hiki iā mākou ke huki i ka hopena he mea koʻikoʻi ka wikiwiki o ka makani e pili ana i ka hopena kānana o ka kānana ea HEPA. ʻO ke kiʻekiʻe o ka wikiwiki o ka makani, ʻoi aku ka haʻahaʻa o ka kānana kānana, ʻoi aku ka maopopo o ka hopena ma ka kānana PTFE, a me ka holoʻokoʻa ʻO ka kānana PTFE he haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka kānana fiberglass, akā ʻoi aku ka haʻahaʻa o kona kūpaʻa ma mua o ka kānana fiber glass. No laila, ʻoi aku ka maikaʻi o ka mea kānana PTFE no ka hana ʻana i kahi kānana maikaʻi a i ʻole sub-kiʻekiʻe, a ʻoi aku ka maikaʻi o ke aniani fiber filter no ka hana ʻana. He kānana maikaʻi a ʻoi loa paha. ʻO ke aniani fiber HEPA kānana me kahi kikoʻī o 610 × 610 × 150mm ka haʻahaʻa ma mua o ka kānana 610 × 610 × 90mm aniani fiber HEPA, a ʻoi aku ka maikaʻi o ka hana kānana ma mua o ka kānana 610 × 610 × 90mm aniani fiber HEPA. I kēia manawa, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā mea kānana PTFE maʻemaʻe ma mua o ke aniani fiber. Eia nō naʻe, ke hoʻohālikelike ʻia me ke aniani fiber, ʻoi aku ka maikaʻi o ka PTFE i ke kūpaʻa wela, ke kūpaʻa corrosion a me ka hydrolysis ma mua o ke aniani fiber. No laila, pono e noʻonoʻo ʻia nā mea like ʻole i ka wā e hana ana i kāna kānana. Hoʻohui i ka hana ʻenehana a me ka hana waiwai.
