Njengoba sonke sazi, igumbi lokuhlanza imithi linezidingo eziphakeme kakhulu zokuhlanzeka nokuphepha. Uma kukhona uthuli ekamelweni lokuhlanza imithi, kuzobangela ukungcola, umonakalo empilweni kanye nezingozi zokuqhuma. Ngakho-ke, ukusetshenziswa kwezihlungi ze-hepa kubaluleke kakhulu. Yiziphi izindinganiso zokusebenzisa izihlungi ze-hepa, isikhathi sokushintsha, imingcele yokushintsha kanye nezinkomba? Igumbi lokuhlanza imithi elinezidingo eziphezulu zokuhlanzeka kufanele lizikhethe kanjani izihlungi ze-hepa?
Egumbini lokuhlanza imithi, izihlungi ze-hepa zisetshenziswa njengezihlungi zokugcina zokwelashwa nokuhlunga umoya ezindaweni zokukhiqiza. Ukukhiqizwa kwe-aseptic kudinga ukusetshenziswa okuphoqelekile kwezihlungi ze-hepa, futhi ngezinye izikhathi kusetshenziswa nokukhiqizwa kwezinhlobo zomthamo eziqinile neziqinile. Amakamelo ahlanzekile emithi ahlukile kwamanye amakamelo ahlanzekile ezimbonini. Umehluko ukuthi lapho kukhishwa amalungiselelo nezinto zokusetshenziswa ezingasenzi amagciwane, akuzona nje izinhlayiya ezilengisiwe emoyeni okumele zilawulwe, kodwa futhi nenani lama-microorganisms kumele lilawulwe. Ngakho-ke, uhlelo lokupholisa umoya esitshalweni semithi luphinde lube nokuhlanza, ukuhlanza, ukubulala amagciwane kanye nezinye izindlela zokulawula ama-microorganisms ngaphakathi kobubanzi bemithetho efanele. Isihlungi somoya sisebenzisa izinto zokuhlunga ezinezimbobo ukuze sibambe uthuli oluvela emoyeni, sihlanze umoya, futhi sihlanze umoya onothuli bese siwuthumela ekamelweni ukuqinisekisa ukuhlanzeka komoya ekamelweni elihlanzekile. Kumakamelo ahlanzekile emithi anezidingo eziphakeme, izihlungi ze-gel seal hepa zivame ukusetshenziselwa ukuhlunga. Isihlungi se-gel seal hepa sisetshenziswa kakhulu ukubamba izinhlayiya ezingaphansi kuka-0.3μm. Inokuvala okungcono, ukusebenza kahle kokuhlunga okuphezulu, ukumelana nokugeleza okuphansi, futhi ingasetshenziswa isikhathi eside ukunciphisa izindleko zezinto ezisetshenziswa kamuva, ihlinzeka ngomoya ohlanzekile we-workshop ehlanzekile yezinkampani zemithi. Izihlungi ze-Hepa ngokuvamile ziyahlolwa ngaphambi kokuphuma efektri, kodwa abangebona ochwepheshe kudingeka banake kakhulu ngesikhathi sokuphathwa nokufakwa. Ngezinye izikhathi kwenzeka ukuthi ukungcola kuvuza kusuka kufreyimu kuye egumbini elihlanzekile ngenxa yokufakwa okungafanele, ngakho-ke ukutholwa kokuvuza kuvame ukwenziwa ngemva kokufakwa ukuqinisekisa ukuthi izinto zokuhlunga zonakele; ukuthi ibhokisi liyavuza; ukuthi isihlungi sifakwe kahle yini. Ukuhlolwa okuvamile kufanele kwenziwe futhi ekusetshenzisweni kamuva ukuqinisekisa ukuthi ukusebenza kahle kokuhlunga kwesihlungi kuhlangabezana nezidingo zokukhiqiza. Izinqubo ezivame ukusetshenziswa zifaka phakathi izihlungi ze-hepa ezincane ze-pleat, izihlungi ze-hepa ezijulile ze-pleat, izihlungi ze-hepa ze-gel seal, njll., ezifeza injongo yokuhlanzeka ngokuhlunga komoya nokugeleza ukuze kuhlungwe izinhlayiya zothuli emoyeni. Umthwalo wesihlungi (ungqimba) kanye nomehluko wengcindezi ephezulu nephansi nakho kubalulekile. Uma umehluko wengcindezi ephezulu nephansi kwesihlungi ukhuphuka, isidingo samandla sohlelo lokuhambisa kanye nomoya wokukhipha umoya sizokhula, ukuze kulondolozwe inani elidingekayo lokushintsha komoya. Umehluko onjalo wengcindezi phakathi kwephezulu nephansi kwesihlungi ungandisa umkhawulo wokusebenza kohlelo lokungenisa umoya. Ngesikhathi sokusetshenziswa, ukuze kuvikelwe isihlungi se-hepa, kufanele kusetshenziswe isihlungi sangaphambili - ngokuvamile isihlungi esincane njenge-F5, F7 kanye nezihlungi ze-F9 (EN779). Isihlungi se-hepa kumele sishintshwe njalo ukuze kuvikelwe isihlungi se-hepa ekuvalekeni.
Kungakhathaliseki ukuthi kuyisihlungi se-hepa esifakwe ekugcineni kweyunithi yokupholisa umoya yokuhlanza noma isihlungi somoya se-hepa esifakwe ebhokisini le-hepa, lezi kumele zibe namarekhodi esikhathi sokusebenza anembile kanye nokuhlanzeka kanye nomthamo womoya njengesisekelo sokushintsha. Isibonelo, ngaphansi kokusetshenziswa okuvamile, impilo yesevisi yesihlungi se-hepa ingaba ngaphezu konyaka owodwa. Uma isivikelo sangaphambili sihle, impilo yesevisi yesihlungi se-hepa ingaba ngaphezu kweminyaka emibili ngaphandle kwenkinga. Vele, lokhu kuncike futhi kwikhwalithi yesihlungi somoya se-hepa, noma ngisho nangaphezulu. Izihlungi ze-hepa ezifakwe emishinini yegumbi elihlanzekile, njengezihlungi ze-hepa egumbini lokugeza umoya, zingaba nempilo yesevisi engaphezu kweminyaka emibili uma isihlungi esiyinhloko sangaphambili sivikelwe kahle; isibonelo, izihlungi ze-hepa ebhentshini lokuhlanza zingashintshwa ngokushesha kwegeyiji yomehluko wokucindezela ebhentshini lokuhlanza. Izihlungi ze-hepa eshedini elihlanzekile zinganquma isikhathi esingcono kakhulu sokushintsha izihlungi zomoya ngokuthola isivinini somoya sezihlungi zomoya ze-hepa. Isibonelo, izihlungi zomoya ze-hepa kuyunithi yesihlungi se-FFU fan zingashintshwa yizixwayiso ohlelweni lokulawula lwe-PLC noma i-gauge yomehluko wokucindezela. Izimo zokufaka esikhundleni izihlungi ze-hepa ezimbonini zemithi ezichazwe ezinhlotsheni zomklamo wegumbi elihlanzekile yilezi: ijubane lokugeleza komoya lincishiswa libe umkhawulo omncane, ngokuvamile lingaphansi kuka-0.35m/s; ukumelana kufinyelela izikhathi eziphindwe kabili kunenani lokuqala lokumelana, futhi ngokuvamile kubekwa izikhathi eziyi-1.5 yizinkampani; uma kukhona ukuvuza okungalungiseki, izindawo zokulungisa akufanele zidlule amaphuzu ama-3, futhi indawo yokulungisa iyonke akufanele idlule u-3%. Endaweni yokulungisa iphuzu elilodwa, akufanele ibe nkulu kune-2*2cm. Abanye babafaki bethu bezihlungi zomoya abanolwazi bafingqe ulwazi olubalulekile. Lapha singathanda ukwethula izihlungi ze-hepa zezimboni zemithi. Sithemba ukuthi lokhu kuzokusiza ukuthi uqonde isikhathi esingcono kakhulu sokushintsha izihlungi zomoya ngokunembe kakhudlwana. Kuyunithi yokupholisa umoya, lapho i-gauge yomehluko wokucindezela ibonisa ukuthi ukumelana kwesihlungi somoya kufinyelela izikhathi eziphindwe kabili kuya kwezithathu ukumelana kokuqala, isihlungi somoya kufanele sigcinwe noma sishintshwe. Uma kungekho gauge yokuhlukanisa ingcindezi, ungasebenzisa ifomethi elandelayo elula yemizimba emibili ukuze unqume ukuthi idinga ukushintshwa yini: qaphela umbala wezinto zokuhlunga ezinhlangothini zomoya eziphezulu nezingezansi zesihlungi somoya. Uma umbala wezinto zokuhlunga endaweni yokukhipha umoya uqala ukuba mnyama, kufanele ulungiselele ukuzishintsha; thinta izinto zokuhlunga ohlangothini lokukhipha umoya lwesihlungi somoya ngesandla sakho. Uma kunothuli oluningi esandleni sakho, kufanele ulungiselele ukuzishintsha; bhala phansi isimo sokufaka isihlungi somoya izikhathi eziningi bese ufingqa umjikelezo omuhle kakhulu wokufaka esikhundleni; uma umehluko wokucindezela phakathi kwegumbi elihlanzekile negumbi eliseduze wehla kakhulu ngaphambi kokuba isihlungi somoya se-hepa sifinyelele ekumelaneni kokugcina, kungenzeka ukuthi ukumelana kwezihlungi zokusebenza eziphambili nezesibili kukhulu kakhulu, futhi kufanele ulungiselele ukuzishintsha; uma ukuhlanzeka ekamelweni elihlanzekile kungahlangabezani nezidingo zomklamo, noma kukhona ingcindezi engemihle, futhi izihlungi zomoya zokusebenza eziphambili nezesibili zingakafiki esikhathini sokufaka esikhundleni, kungenzeka ukuthi ukumelana kwesihlungi somoya se-hepa kukhulu kakhulu, futhi kufanele ulungiselele ukuzishintsha.
Ngaphansi kokusetshenziswa okuvamile, isihlungi se-hepa siyashintshwa kanye njalo eminyakeni eyi-1 kuya kwemibili (kuye ngokuthi ikhwalithi yomoya ezindaweni ezahlukene), futhi le datha iyahlukahluka kakhulu. Idatha ye-empirical ingatholakala kuphela kuphrojekthi ethile ngemuva kokuqinisekiswa kokusebenza kwegumbi elihlanzekile, futhi idatha ye-empirical efanele igumbi elihlanzekile inganikezwa kuphela ekamelweni lokugeza umoya legumbi elihlanzekile. Izici ezithinta impilo yesevisi yesihlungi se-hepa:
1. Izici zangaphandle:
1. Indawo engaphandle. Uma kunomgwaqo omkhulu noma umgwaqo ongaphandle kwegumbi elihlanzekile, kunothuli oluningi, oluzothinta ngqo ukusetshenziswa kwesihlungi se-hepa futhi impilo izoncipha kakhulu. (Ngakho-ke, ukukhetha indawo kubaluleke kakhulu)
2. Iziphetho zangaphambili neziphakathi zomsele wokungenisa umoya zivame ukuhlonyiswa ngezihlungi eziyinhloko nezisebenzayo kahle emaphethelweni angaphambili naphakathi omsele wokungenisa umoya. Inhloso ukuvikela nokusebenzisa kangcono isihlungi se-hepa, ukunciphisa inani lokufaka esikhundleni, nokunciphisa izindleko zokusebenzisa. Uma ukuhlunga okungaphambili kungaphathwa kahle, impilo yesevisi yesihlungi se-hepa nayo izofinyezwa. Uma izihlungi eziyinhloko nezisebenzayo kahle zisuswa ngqo, isikhathi sokusetshenziswa kwesihlungi se-hepa sizofinyezwa kakhulu.
2. Izici zangaphakathi: Njengoba sonke sazi, indawo yokuhlunga esebenza kahle yesihlungi se-hepa, okungukuthi, amandla ayo okugcina uthuli, ithinta ngqo ukusetshenziswa kwesihlungi se-hepa. Ukusetshenziswa kwayo kuhambelana nendawo yokuhlunga esebenza kahle. Uma indawo esebenza kahle inkulu, ukumelana kwayo kuncane futhi isikhathi sayo sokuyisebenzisa side. Kunconywa ukuthi unake kakhulu indawo yayo yokuhlunga esebenza kahle kanye nokumelana lapho ukhetha isihlungi somoya se-hepa. Ukuphambuka kwesihlungi se-Hepa akunakugwenywa. Ukuthi sidinga ukushintshwa noma ngabe sidinga ukusatshalaliswa kuncike ekuhlolweni nasekuhlolweni kwendawo. Uma izinga lokufaka esikhundleni selifinyelelwe, sidinga ukuhlolwa futhi sishintshwa. Ngakho-ke, inani elibonakalayo lempilo yesihlungi alikwazi ukukhuliswa ngokungahleliwe.
