Kuyini "isihlungi somoya"?
Isihlungi somoya idivayisi ethwebula i-particle ngesenzo sezinto zokuhlunga ezinama-porous futhi ihlanze umoya. Ngemuva kokuhlanzwa komoya, kuthunyelwa ngaphakathi endlini ukuze kuqinisekiswe izidingo zenqubo yamakamelo ahlanzekile kanye nokuhlanzeka komoya emakamelweni ajwayelekile ane-air conditioning. Izindlela zokuhlunga ezaziwayo njengamanje zakhiwe ikakhulukazi imithelela emihlanu: umphumela wokucasha, umphumela ongasebenzi, umphumela wokusabalalisa, amandla adonsela phansi, kanye nomphumela we-electrostatic.
Ngokwezidingo zokusetshenziswa kwezimboni ezahlukene, izihlungi zomoya zingahlukaniswa zibe isihlungi esiyinhloko, isihlungi esiphakathi, isihlungi se-hepa nesihlungi se-ultra-hepa.
Indlela yokukhetha isihlungi somoya ngokufanele?
01. Nquma ngokunengqondo ukusebenza kahle kwezihlungi kuwo wonke amaleveli ngokusekelwe kuzimo zohlelo lokusebenza.
Izihlungi eziyinhloko nezimaphakathi: Zisetshenziswa kakhulu ekuhlanzeni umoya kanye nezinhlelo zokupholisa umoya. Umsebenzi wabo oyinhloko ukuvikela izihlungi ezansi nomfula kanye nepuleti lokushisisa elipholile leyunithi ye-air conditioning ukuze lingavaleki futhi andise impilo yazo yesevisi.
Isihlungi se-Hepa/ultra-hepa: silungele izimo zokufaka izicelo ezinezidingo zokuhlanzeka okuphezulu, njengezindawo ezinikezela ngendawo yokupholisa umoya endaweni yokusebenzela ehlanzekile engenalo izintuli esibhedlela, ukukhiqizwa kwe-electronic optics, ukukhiqizwa kwezinsimbi ezinembayo nezinye izimboni.
Ngokuvamile, isihlungi setheminali sinquma ukuthi umoya uhlanzeke kangakanani. Izihlungi ezikhuphukayo kuwo wonke amaleveli zidlala indima yokuvikela ukuze zandise impilo yazo yesevisi.
Ukusebenza kahle kwezihlungi esigabeni ngasinye kufanele kumiswe ngendlela efanele. Uma ukucaciswa kokusebenza kahle kwezigaba ezimbili ezincikene zezihlungi kuhluke kakhulu, isigaba sangaphambilini ngeke sikwazi ukuvikela isigaba esilandelayo; uma umehluko phakathi kwezigaba ezimbili ungahlukanga kakhulu, isigaba sokugcina sizoba nomthwalo.
Ukucushwa okunengqondo ukuthi uma usebenzisa ukuhlukaniswa kokucaciswa kokusebenza kahle kwe-"GMFEHU", setha isihlungi sezinga lokuqala njalo ngezinyathelo ezi-2 - 4.
Ngaphambi kwesihlungi se-hepa ekugcineni kwegumbi elihlanzekile, kufanele kube nesihlungi esinemininingwane esebenza kahle engekho ngaphansi kuka-F8 ukuze sisivikele.
Ukusebenza kwesihlungi sokugcina kufanele kube okuthembekile, ukusebenza kahle kanye nokucushwa kwesihlungi sangaphambili kufanele kube okunengqondo, futhi ukugcinwa kwesihlungi sokuqala kufanele kube lula.
02. Bheka imingcele eyinhloko yesihlungi
Ivolumu yomoya elinganiselwe: Ezihlungi ezinesakhiwo esifanayo kanye nezinto ezifanayo zokuhlunga, lapho ukumelana kokugcina kunqunywa, indawo yokuhlunga inyuka ngo-50%, futhi impilo yesevisi yesihlungi izonwetshwa ngo-70% -80%. Uma indawo yokuhlunga iphinda kabili, impilo yesevisi yesihlungi izoba yinde ngokuphindwe kathathu kuneyokuqala.
Ukumelana kokuqala nokumelana kokugcina kwesihlungi: Isihlungi sakha ukumelana nokugeleza komoya, futhi ukunqwabelana kothuli kusihlungi kuyanda ngesikhathi sokusebenzisa. Lapho ukumelana nesihlungi kukhula kunani elithile elishiwo, isihlungi siyachithwa.
Ukumelana nesihlungi esisha kubizwa ngokuthi "ukumelana kokuqala", futhi inani lokumelana elihambisana nesikhathi lapho isihlungi sichithwa sibizwa ngokuthi "ukumelana kokugcina". Amanye amasampula okuhlunga anemingcele "yokugcina ukumelana", futhi onjiniyela bezinto zomoya bangashintsha umkhiqizo ngokuya ngezimo zesayithi. Inani lokugcina lokumelana lomklamo wokuqala. Ezimweni eziningi, ukumelana kokugcina kwesihlungi esisetshenziswe kusayithi izikhathi ezingu-2-4 zokumelana kokuqala.
Ukumelana kokugcina okunconyiwe (Pa)
I-G3-G4 (isihlungi esiyinhloko) 100-120
I-F5-F6 (isihlungi esimaphakathi) 250-300
F7-F8 (high-medium filter) 300-400
I-F9-E11 (isihlungi se-sub-hepa) 400-450
I-H13-U17 (isihlungi se-hepa, isihlungi se-ultra-hepa) 400-600
Ukusebenza kahle kokuhlunga: "Ukusebenza kahle kokuhlunga" kwesihlungi somoya kubhekisela esilinganisweni senani lothuli oluthathwe isihlungi nothuli lomoya wokuqala. Ukunqunywa kokusebenza kahle kokuhlunga akuhlukaniseki endleleni yokuhlola. Uma isihlungi esifanayo sihlolwa kusetshenziswa izindlela zokuhlola ezihlukene, amanani okusebenza kahle atholakele azohluka. Ngakho-ke, ngaphandle kwezindlela zokuhlola, ukusebenza kahle kokuhlunga akunakwenzeka ukukhuluma ngakho.
Umthamo wokubamba uthuli: Umthamo wokubamba uthuli wesihlungi ubhekisela enanini eliphakeme elivumelekile lokunqwabelana kothuli lesihlungi. Uma inani lokuqoqwa kothuli lidlula leli nani, ukumelana nesihlungi kuzokwanda futhi ukusebenza kahle kokuhlunga kuzokwehla. Ngakho-ke, ngokuvamile kushiwo ukuthi umthamo wokubamba uthuli wesihlungi ubhekisela enanini lothuli oluqoqwe lapho ukumelana ngenxa yokuqoqwa kothuli kufinyelela inani elishiwo (ngokuvamile kabili ukumelana kokuqala) ngaphansi komthamo othile womoya.
03. Buka ukuhlolwa kwesihlungi
Ziningi izindlela zokuhlola ukusebenza kahle kokuhlunga kwesihlungi: indlela ye-gravimetric, indlela yokubala uthuli lwasemkhathini, indlela yokubala, ukuskena kwe-photometer, indlela yokubala yokuskena, njll.
Ukubala Indlela Yeskena (Indlela ye-MPPS) Usayizi Wezinhlayiyana Ongeneka Kakhulu
Indlela ye-MPPS okwamanje iyindlela yokuhlola evamile yezihlungi ze-hepa emhlabeni, futhi iyindlela eqinile kakhulu yokuhlola izihlungi ze-hepa.
Sebenzisa ikhawunta ukuze uskene ngokuqhubekayo futhi uhlole yonke indawo yokukhipha umoya yesihlungi. Ikhawunta inikeza inombolo kanye nosayizi wezinhlayiyana zothuli endaweni ngayinye. Le ndlela ayikwazi nje ukulinganisa ukusebenza kahle okumaphakathi kwesihlungi, kodwa futhi iqhathanise ukusebenza kahle kwendawo kwephuzu ngalinye.
