Mukamagula chowumitsira pamanja cha FEEGOO , nthawi zonse mumamva mawu oti "SEFA ya HEPA" yomwe amalonda amatchula, koma anthu ambiri sakudziwabe zambiri za fyuluta ya HEPA, ndipo kumvetsetsa kwawo kumakhalabe pamtunda wa "zosefera zapamwamba" .mlingo.

Kodi fyuluta ya HEPA ya Hand dryer ndi chiyani?

Fyuluta ya HEPA imatchedwanso HEPA high-efficiency particulate fyuluta, dzina lonse la Chingerezi ndi High-efficiency particulate arrestance.

Zosefera za HEPA nthawi zambiri zimapangidwa ndi polypropylene kapena zinthu zina zophatikizika, ndipo zambiri sizitha kutsuka.Zosefera zochepa za HEPA zopangidwa ndi PET zimatha kutsukidwa ndi madzi, koma kusefa kwa zosefera zotere ndizochepa.

Zosefera zambiri za HEPA zomwe zimagwiritsidwa ntchito mumpweya wabwino zili pansipa.Kuti awonjezere mphamvu yogwira fumbi, mapindikidwe ambiri amapindika, ndipo mawonekedwe ake amamveka ngati pepala lochindikala.

Kodi fyuluta ya HEPA ya Jet Hand dryer imagwira ntchito bwanji?

Zosefera za HEPA zimasefa m'mitundu inayi: kulowera, mphamvu yokoka, kuyenda kwa mpweya ndi mphamvu za van der Waals

1 Njira yolowera ndi sefa yomwe aliyense amamvetsetsa.Nthawi zambiri, tinthu tating'onoting'ono ta 5 μm ndi 10 μm timalandidwa ndi "sefe".

2. Potengera mphamvu yokoka, tinthu tating'onoting'ono tokhala ndi kachulukidwe kakang'ono komanso kachulukidwe kakang'ono timachepetsa liwiro lawo podutsa HEPA, ndipo mwachilengedwe zimakhazikika pa fyuluta ya HEPA ngati sediment ikumira pansi pa mtsinje.

3 Chophimba cha fyuluta chimalukidwa mosagwirizana kuti chipangitse kuchuluka kwa ma vortices a mpweya, ndipo tinthu tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono ta HEPA fyuluta yopangidwa ndi mphepo yamkuntho.

4 Tinthu tating'onoting'ono tating'onoting'ono timapanga kusuntha kwa Brownian kugunda gawo la HEPA fiber, ndipo amayeretsedwa ndi mphamvu ya van der Waals.Mwachitsanzo, onyamula ma virus omwe ali pansi pa 0,3 μm amayeretsedwa mothandizidwa ndi mphamvu iyi.

Mphamvu ya Van der Waals: mphamvu ya intermolecular, yomwe imatanthawuza mphamvu yomwe ilipo pakati pa mamolekyu (mamolekyu) ndi mamolekyu kapena pakati pa mpweya wabwino (gasi wabwino) ndi maatomu (maatomu).

Zosefera za HEPA

Nthawi zonse ndimamva wina akunena "sefa yomwe ndimagwiritsa ntchito ndi H12", ndiye "H12" muyeso wowunika pano ndi wotani?

Malinga ndi muyezo wa EU EN1882, molingana ndi kusefera bwino, timagawa fyuluta ya HEPAl m'makalasi 5: fyuluta yowoneka bwino, zosefera zapakatikati, zosefera zocheperako, zosefera za HEPA komanso zosefera zapamwamba kwambiri.

Sefa yokhala ndi kusefera bwino kwambiri kuposa 99.9% ya tinthu tating'onoting'ono tokhala ndi tinthu tating'ono 0.3 μm imatchedwa H12.

Kusamvetsetsana Kwachilendo kwa Zosefera Zamanja za HEPA Zosefera

Bodza loyamba: Kuchulukitsitsa kwa tinthu tating'onoting'ono, ndikosavuta kuchotsa ndi HEPA?

Kusanthula: Mfundo yoyeretsera fyuluta ya HEPA sikungosefa tinthu tokulirapo kuposa mauna ngati sieve kuti muyeretse mpweya.M'malo mwake, imadalira mphamvu ya van der Waals pakati pa tinthu tating'onoting'ono ndi fyuluta kuti ipange mawonekedwe a adsorption, ndipo imakhala ndi kusefera bwino kwa tinthu tating'onoting'ono toposa 0.5 μm ndi pansi pa 0.1 μm.

Tinthu tating'onoting'ono ta 0.1 μm timagwira ntchito ya Brownian.Tinthu tating'onoting'ono tating'onoting'ono, kusuntha kwa Brownian kumakhala kolimba, ndipo nthawi zambiri kumenyedwa, kumapangitsanso bwino kutsatsa.

Ndipo tinthu tating'onoting'ono ta 0.5μm timachita kuyenda mopanda mphamvu, kuchulukirachulukira, kuchuluka kwa inertia, komanso kusefa bwino.

Mosiyana ndi izi, tinthu tating'onoting'ono ta 0.1-0.3 μm zakhala zovuta kuchotsa HEPA.Ichi ndichifukwa chake makampani amatanthauzira kalasi ya HEPA yosefera ndi kusefera kwa tinthu tating'onoting'ono ta 0.3μm.

Kusamvetsetsa 2: The kuyeretsedwa dzuwa kwa HEPA kwa 0.3μm microparticles akhoza kufika oposa 99.97%, kotero kuyeretsedwa kwake pa 0.1μm microparticles si wotsimikizika, chabwino?

Kusanthula: Mofanana ndi kusamvetsetsana, PM0.3 ndiyosavuta kudutsa chitetezo cha HEPA fyuluta, chifukwa sichikhudzidwa kwambiri ndi mphamvu ya van der Waals.Choncho, fyuluta yokhala ndi zotsatira za 99.97% pa PM0.3 ikhoza kukhala yothandiza kwambiri pa PM0.1.Chabwino, ngakhale 99.99%.

Bodza lachitatu: Kukwera kwa kusefera kwa HEPA, kuli bwino?

Kusanthula: Chilichonse chachuluka.Kukwera kwa HEPA kusefera bwino, kumapangitsa kukana kwambiri, komanso kuchuluka kwa mpweya weniweniwo kumachepetsedwa.Kuchuluka kwa mpweya kumachepa, chiwerengero cha kuyeretsedwa pa nthawi ya unit chidzachepanso, ndipo kuyeretsa bwino kudzachepa.

Chifukwa chake, kuphatikiza koyenera kwambiri kwa fan, fyuluta ndi kapangidwe ka kayendedwe ka mpweya kumatha kukhala ndi chitsanzo chabwino kwambiri.

Kodi fyuluta ya HEPA iyenera kusinthidwa kangati?

Pomaliza, kubwerera ku funso lomwe aliyense akuda nkhawa nalo, ndi kangati fyuluta ya HEPA ikufunika kusinthidwa?

Chizindikiro chachikulu choweruza moyo wautumiki wa fyuluta ndi mphamvu yogwira fumbi.Deta yapakati yomwe imakhudza mphamvu yogwira fumbi ndi malo owonjezera a zenera la fyuluta.Kukula kokulirapo kwa zosefera kumapangitsa kuti fumbi likhale lokwera kwambiri komanso mawonekedwe a fyuluta amakhala olimba.

Fumbi kugwira mphamvu amatanthauza kuchuluka kwa fumbi kudzikundikira pamene kukana chifukwa fumbi kudzikundikira kufika pa mtengo wapadera (nthawi zambiri 2 kukana koyamba) pansi pa zochita za voliyumu ya mpweya.

Koma kwa ogwiritsa ntchito wamba, maziko oweruza m'malo mwa fyuluta ndikuwonera ndi maso.

Ndizosagwirizana ndi sayansi kuweruza ngati fyulutayo iyenera kusinthidwa ndi njira yowonera maso.Ikhoza kugwiritsira ntchito mopitirira muyeso, kubweretsa kuipitsidwa kwachiwiri, ndipo ikhoza "kuchotsa" fyuluta pasadakhale popanda kukulitsa mtengo wake wogwiritsa ntchito.

FEEGOO imagwiritsa ntchito algorithm ya Gaussian yosokonekera kuwerengera kuchulukana kwafumbi kuchotsedwa kwa fyuluta, ndipo imalimbikitsa makasitomala kuti asinthe fyuluta yowumitsira m'manja yogwira ntchito kwambiri kamodzi miyezi isanu ndi umodzi iliyonse.
