Paunenge uchitenga FEEGOO yekuomesa ruoko, unogara uchinzwa izwi rekuti "HEPA sefa" richitaurwa nevatengesi, asi vanhu vazhinji havasati vaziva zvakawanda nezve HEPA sefa, uye manzwisisiro avo pamusoro payo anoramba ari padanho repamusoro re "advanced filter" .level.

Chii chinonzi Hand dryer HEPA sefa?

HEPA sefa inodaidzwa zvakare kuti HEPA yakakwira-inoshanda particulate sefa, iro zita rakazara rechirungu ndiro High-effective particulate arrestance.

HEPA mafirita anowanzo kugadzirwa nepolypropylene kana zvimwe zvinhu zvinoumbwa, uye mazhinji acho haagezeke.Nhamba shoma yemafirita eHEPA akagadzirwa nePET anogona kugezwa nemvura, asi kusefa kwemasefa akadaro kwakadzikira.

Mazhinji eHEPA mafirita anoshandiswa mumhepo nyowani sisitimu anoratidzwa pazasi.Kuti vawedzere simba ravo rekubata guruva, mapete akawanda anopetwa, uye magadzirirwo acho anonzwa kunge bepa gobvu.

Jet Hand dryer HEPA sefa inoshanda sei?

HEPA mafirita anosefa kuburikidza ne4 mafomu: kupindira, giravhiti, kuyerera kwemhepo uye van der Waals masimba

1 Mucheno wekucheka ndiyo sefa inowanzonzwisiswa nemunhu wese.Kazhinji, zvikamu zvakakura zve 5 μm uye 10 μm zvinogamuchirwa uye "seved".

2. Pasi pesimba regiravhiti, zvimedu zveguruva zvine vhoriyamu diki uye density yakakwira zvinoderedza kukurumidza kwadzo pazvinopfuura nemuHEPA, uye zvinogara zviri paHEPA sefa sediment inonyura pasi perwizi.

3 Chidzitiro chesefa chakarukwa zvisina kuenzana kuti chigadzire huwandu hukuru hwemhepo, uye zvidimbu zvidiki zvakashambadzirwa paHEPA sefa skrini pasi pekuita kwechamupupuri chemhepo.

4 Iwo ma ultrafine particles anoita Brownian motion kurova HEPA faibha layer, uye anocheneswa nesimba revan der Waals force.Semuenzaniso, vatakuri vehutachiona pazasi 0.3 μm vanocheneswa pasi pesimba resimba iri.

Van der Waals force: the intermolecular force, zvinoreva simba riripo pakati pemamorekuru (morekuru) nemamorekuru kana pakati pemagasi akanaka (noble gas) nemaatomu (atomu).

HEPA sefa chiyero

Ndinogara ndichinzwa mumwe munhu achiti "sefa yandinoshandisa iH12", saka "H12" chiyero chekuongorora pano chii?

Zvinoenderana neEU EN1882 yakajairwa, zvinoenderana nekusefa kwakanaka, isu tinokamura HEPAl sefa kuita 5 mamakisi: coarse sefa, yepakati-inoshanda sefa, sub-yakakwirira-inoshanda sefa, HEPA yakakwirira-inoshanda sefa uye yekupedzisira-yepamusoro-inoshanda sefa.

Sefa ine kusefa inoshanda yakakwira kupfuura 99.9% yezvimedu zvine saizi ye0.3 μm inonzi H12.

Kusanzwisisana kwakajairika kweHand dryer HEPA Mafirita

Nhema 1: Iyo yakakura huwandu hwezvinhu, zviri nyore kubviswa neHEPA?

Ongororo: Nheyo yekuchenesa yeHEPA sefa haisi yekusefa kunze zvidimbu zvakakura kupfuura mesh sesefa yekuchenesa mweya.Panzvimbo iyoyo, inotsamira pane van der Waals simba pakati pezvakanaka zvimedu uye sefa kuti igadzire iyo adsorption mhedzisiro, uye ine yakanaka kusefa inoshanda kune zvimedu zviri pamusoro pe0.5 μm uye pazasi 0.1 μm.

Zvimedu pazasi 0.1 μm zvinoita Brownian kufamba.Iyo diki diki iri, iyo yakasimba iyo Brownian motion iri, uye nguva zhinji yainorohwa, zviri nani iyo adsorption mhedzisiro.

Uye zvimedu zviri pamusoro pe 0.5μm zvinoita inertial motion, iyo yakakura kuwanda, yakakura inertia, uye zviri nani kusefa mhedzisiro.

Kusiyana neizvi, zvimedu zvine dhayamita ye0.1-0.3 μm zvave zvakaoma kubvisa HEPA.Ichi ndicho chikonzero indasitiri ichitsanangura HEPA sefa giredhi ine filtration rate ye 0.3μm zvimedu.

Kusanzwisisa 2: Kucheneswa kweHEPA kwe 0.3μm microparticles kunogona kusvika kupfuura 99.97%, saka kucheneswa kwayo pa 0.1μm microparticles hakuna chokwadi, handiti?

Kuongorora: Nenzira imwecheteyo nekusanzwisisana, PM0.3 iri nyore kupaza nekuchengetedzwa kweHEPA sefa, nokuti hainyanyi kubatwa nechisimba chevan der Waals simba.Naizvozvo, sefa ine 99.97% mhedzisiro paPM0.3 inogona kushanda zvakanyanya paPM0.1.Zvakanaka, kunyange 99.99%.

Nhema 3: Iyo yakakwirira iyo HEPA kusefa kunyatsoita, zviri nani?

Ongororo: Chero chinhu chakawandisa.Iyo yakakwirira iyo HEPA kusefa kunyatsoita, iyo yakakura kuramba, uye iyo chaiyo yemhepo vhoriyamu ichaderedzwa.Kana huwandu hwemhepo huchidzikira, huwandu hwekucheneswa pane imwe nguva yeyuniti huchadzikirawo, uye kushanda kwekuchenesa kunoderera.

Naizvozvo, iyo chete inonzwisisika musanganiswa wefani, sefa uye kutenderera kwemhepo dhizaini inogona kuwana yakanakisa modhi.

Kangani iyo Hand dryer HEPA sefa inofanira kutsiviwa?

Pakupedzisira, kudzokera kumubvunzo uyo munhu wese ane hanya nawo, kangani iyo HEPA sefa inoda kutsiviwa?

Chiratidzo chepakati chekutonga hupenyu hwesevhisi yehupfu inobata simba.Iyo yepakati data inobata guruva inobata simba inzvimbo yekuwedzera yefirita skrini.Iyo yakakura nzvimbo yekuwedzera yesefa skrini, iyo inokwirisa guruva inobata simba uye inosimba yakasimba sefa skrini.

Dust holding capacity inoreva kuwanda kwehuruva kuunganidza kana kushorwa nekuda kwekuunganidzwa kweguruva kunosvika pamutengo wakatarwa (kazhinji 2 times the first resistance) pasi pekuita kwehumwe huwandu hwemhepo.

Asi kune vashandisiwo zvavo, hwaro hwekutonga kutsiva kwesefa ndeyekutarisa neziso rakashama.

Hazvisi zvesainzi kutonga kana sefa ichifanirwa kutsiviwa nenzira yekuona maziso asina kupfeka.Inogona kushandisa zvakanyanya sefa, zvichikonzera kusvibiswa kwechipiri, uye inogona zvakare "kuregedza" sefa pamberi pasina kuwedzera kukosha kwayo kwekushandisa.

FEEGOO inoshandisa iyo Gaussian fuzzy algorithm kuverenga iyo yakawedzera guruva kubviswa kwesefa, uye inokurudzira kuti vatengi vatsive yakakwirira-inoshanda sefa yeoomesa ruoko kamwe chete mwedzi mitanhatu yega yega.
