Amakhasimende amaningi asebenzisaizihlungi zokuhlanza umoyaingase ibe nombuzo mayelana nokuthi isihlungi sokuhlanza umoya kufanele sishintshwe nini, ngokuvamile kunezindlela ezintathu esingazikhetha ukubhekana nenkinga.
Isiphakamiso 1: Ngokombala wezinto zokuhlunga
Imidiya yesihlungi se-HEPAbabe nezinhlangothi ezimbili, uhlangothi lapho umoya ogeleza khona lubizwa ngokuthi uhlangothi olungaphambili noma olubheke ngasemoyeni, kanti uhlangothi lapho umoya uphuma khona lubizwa ngokuthi i-leeward noma uhlangothi olungemuva.Uma uhlangothi olungemuva lwesihlungi luba mpunga ngokumnyama noma lube mnyama, isihlungi sidinga ukushintshwa.Ngokuvamile, umbala wezinto zokuhlunga umhlophe noma umhlophe phuzi ngaphambi kokusetshenziswa (eminye imikhiqizo yengeza ungqimba lwefilimu elwa namagciwane eluhlaza okwesibhakabhaka noma esiliva ohlangothini olungaphambili lwesihlungi, kodwa okokuhlunga ngokwako kusemhlophe noma kuphuzi kancane), ukusetshenziswa okuqhubekayo kwezihlanzi zomoya, umbala wezinto zokuhlunga kancane kancane uba mnyama, okubangelwa ikakhulukazi izinhlayiya ezishumekwe emiculweni yezinto zokuhlunga.Lokhu kubangelwa ikakhulukazi izinhlayiya ezifakwe emicu yento yokuhlunga.Indawo yezinhlayiya ezihlala kusihlungi izohluka ngamaleveli ahlukene okuhlunga.Uma izinga lokuhlunga liphakeme, mancane amathuba okuthi ingemuva lesihlungi libe mnyama, kuyanciphaIqiniso H13(ukuhlunga kahle kwama-microns angu-0.3 noma izinhlayiya eziningi ezinkulu noma ezilingana nezihlungi ezingu-99.97%), ngisho noma ukusetshenziswa okuqhubekayo emahoreni angama-24 ngosuku iminyaka engu-1-2, ingemuva lesihlungi limhlophe njengento entsha kuyilapho ingaphambili lizoba kakhulu. mnyama.
Isiphakamiso sesi-2: Ngokwephunga elikhishwa isisefo
Ngokuvamile isihlanzi somoya asisusi i-PM2.5 kuphela, kodwa futhi siyakwazi ukubhekana ne-formaldehyde, i-toluene, i-TVOC, i-ammonia, i-hydrogen sulfide, i-sulphur dioxide nezinye iphunga.Futhi iyunithi yekhabhoni ecushiwe noma yokuqeda iphunga enekhabhoni ecushiwe njengesiphathi kuyisixazululo esiphephile nesisebenza kangcono sokususa amagesi ayingozi.Kodwa-ke, i-carbon activated izogcwala ngemva kwesikhathi esithile, lapho amandla ayo okubhekana namagesi ayingozi encipha kakhulu, futhi ngisho negesi ekhangisiwe esikhathini esidlule izophunyuka.Ngaleso sikhathi ukuhlanzwa komoya cishe kuzokhipha iphunga elibi, okusho ukuthi isihlungi sidinga ukushintshwa.
Isiphakamiso 3: Ngokuvumelana ne-PM2.5
Uma unomtshina we-PM2.5, ungaqhathanisa izinga lokukhishwa komshini esimweni esisha esivuliwe futhi esisetshenziswe isikhathi esithile, lapho izinga lokususa lehla ngo-50% ungakwazi ukufaka isihlungi.Leli zinga lisebenza kuphela kuIzihlungi ze-HEPA.
