Izihlungi ze-Hepa okwamanje ziyimishini ehlanzekile ethandwayo futhi ziyingxenye ebalulekile yokuvikelwa kwemvelo yezimboni. Njengohlobo olusha lwemishini ehlanzekile, isici sayo ukuthi ingabamba izinhlayiya ezincane ezisukela ku-0.1 kuya ku-0.5um, futhi inomphumela omuhle wokuhlunga kwezinye izinto ezingcolisayo, ngaleyo ndlela iqinisekise ukuthuthukiswa kwekhwalithi yomoya futhi inikeze indawo efanele yokuphila kwabantu kanye nokukhiqizwa kwezimboni.
Isendlalelo sokuhlunga sezihlungi ze-hepa sinemisebenzi emine eyinhloko yokubamba izinhlayiya:
1. Umphumela wokuvalela: Lapho inhlayiya yobukhulu obuthile isondela ebusweni be-fiber, ibanga ukusuka emugqeni ophakathi kuya ebusweni be-fiber lingaphansi kwe-radius yezinhlayiya, futhi inhlayiya izovinjelwa yi-fiber yezinto zokuhlunga bese ifakwa.
2. Umphumela we-Inertia: Uma izinhlayiya zinesisindo esikhulu noma ijubane, zishayisana nobuso be-fiber ngenxa ye-inertia kanye ne-deposit.
3. Umphumela we-electrostatic: Zombili imicu nezinhlayiya zingathwala amashaja, zidale umphumela we-electrostatic odonsela izinhlayiya futhi uzimunce.
4. Ukunyakaza kokusabalalisa: isibonelo sosayizi wezinhlayiya ezincane Ukunyakaza kwe-Brownian kunamandla futhi kulula ukushayisana nobuso befayibha kanye nediphozithi.
Isihlungi se-hepa esincane se-pleat
Kunezinhlobo eziningi zezihlungi ze-hepa, futhi izihlungi ze-hepa ezahlukene zinemiphumela ehlukene yokusetshenziswa. Phakathi kwazo, izihlungi ze-hepa ezincane ezithambile zivame ukusetshenziswa njengemishini yokuhlunga, ngokuvamile zisebenza njengokuphela kohlelo lwemishini yokuhlunga ukuze kuhlungwe kahle futhi kunembile. Kodwa-ke, isici esiyinhloko sezihlungi ze-hepa ezingenazo izihlukanisi ukungabikho komklamo wokuhlukanisa, lapho iphepha lokuhlunga ligoqwa khona futhi lenziwe ngokuqondile, okuphambene nezihlungi ezinezihlukanisi, kodwa kungafinyelela imiphumela emihle yokuhlunga. Umehluko phakathi kwezihlungi ze-hepa ezincane nezithambile: Kungani umklamo ongenazo izihlukanisi ubizwa ngokuthi isihlungi se-hepa esithambile esithambile? Isici sawo esihle ukungabikho kwezihlukanisi. Lapho kuklanywa, kwakukhona izinhlobo ezimbili zezihlungi, esinye esinezihlukanisi kanti esinye asinazo izihlukanisi. Kodwa-ke, kwatholakala ukuthi zombili izinhlobo zinemiphumela efanayo yokuhlunga futhi zingahlanza izindawo ezahlukene. Ngakho-ke, izihlungi ze-hepa ezincane ezithambile zazisetshenziswa kabanzi.
Umklamo wesihlungi se-mini pleat hepa awugcini nje ngokuhlukanisa eminye imishini yokuhlunga, kodwa futhi waklanywa ngokwezidingo zokusetshenziswa, okungafeza imiphumela eminye imishini engenakuyifinyelela. Nakuba izihlungi zinemiphumela emihle yokuhlunga, azikho imishini eminingi engahlangabezana nezidingo zokuhlanza nokuhlunga kwezinye izindawo, ngakho-ke ukukhiqizwa kwezihlungi ze-mini pleat hepa kuyadingeka kakhulu. Isihlungi se-mini pleat hepa singahlunga izinhlayiya ezincane ezilengayo futhi sihlanze ukungcola komoya ngangokunokwenzeka. Ngokuvamile sisetshenziswa ekugcineni kwamadivayisi ohlelo lwemishini ukuhlangabezana nezidingo zabantu zokuhlanza ngokuhlanzwa okuphumelelayo. Okungenhla umehluko phakathi kwezihlungi ze-mini pleat hepa. Eqinisweni, lapho kuklanywa izihlungi, ukugxila akugcini nje ekwandiseni ukusebenza kwazo, kodwa futhi nasekuhlangabezaneni nezidingo zokusetshenziswa. Ngakho-ke, isihlungi se-mini pleat hepa saklanywa ekugcineni. Ukusetshenziswa kwezihlungi ze-mini pleat hepa kuvamile kakhulu futhi sekuyinto yokuhlunga ezindaweni eziningi.
Isihlungi se-hepa esijulile
Njengoba inani lezinhlayiya ezihlungiwe landa, ukusebenza kahle kokuhlunga kwesendlalelo sesihlungi kuzoncipha, kuyilapho ukumelana kuzokwanda. Uma sifinyelela inani elithile, kufanele sishintshwe ngesikhathi esifanele ukuqinisekisa ukuhlanzeka kokuhlanzwa. Isihlungi se-hepa esijulile sisebenzisa i-Hot-melt adhesive esikhundleni se-aluminium foil ene-separator filter ukuze sihlukanise izinto zesihlungi. Ngenxa yokungabikho kwezingxenye, isihlungi se-hepa esincane esingu-50mm ubukhulu singafeza ukusebenza kwesihlungi se-hepa esijulile esingu-150mm ubukhulu. Singahlangabezana nezidingo eziqinile zesikhala, isisindo, kanye nokusetshenziswa kwamandla okuhlukahlukene kokuhlanza umoya namuhla.
Ezihlungini zomoya, imisebenzi eyinhloko edlalwayo isakhiwo sesakhi sesihlungi kanye nezinto zokuhlunga, ezinokusebenza kokuhlunga futhi ezihlala zithinta ukusebenza kwesihlungi somoya. Ngokombono othile, izinto ziyisici esiyinhloko esinquma ukusebenza kwezihlungi. Isibonelo, izihlungi ezine-activated carbon njengenhloko yesihlungi kanye nezihlungi ezinephepha lesihlungi se-glass fiber njengenhloko yesihlungi esiyinhloko zizoba nomehluko omkhulu ekusebenzeni.
Uma sikhuluma ngokufana, ezinye izinto ezinobubanzi obuncane besakhiwo zisebenza kahle ekuhlungeni, njengezakhiwo zephepha le-fiber yengilazi, ezakhiwe ngemicu yengilazi emincane kakhulu futhi zamukela izinqubo ezikhethekile zokwakha isakhiwo esifana nokuluka okunezingqimba eziningi, okungathuthukisa kakhulu ukusebenza kahle kokumuncwa. Ngakho-ke, isakhiwo sephepha le-fiberglass esinembile kangaka ngokuvamile sisetshenziswa njengesici sokuhlunga sezihlungi ze-hepa, kuyilapho esakhiweni sesici sokuhlunga sezihlungi eziyinhloko, izakhiwo zikakotini zokuhlunga ezinobubanzi obukhulu nezinto ezilula zivame ukusetshenziswa.
