Zipinda zoyera zimatchedwanso zipinda zopanda fumbi. Zimagwiritsidwa ntchito kutulutsa zinthu zoipitsa monga tinthu ta fumbi, mpweya woipa, ndi mabakiteriya mumlengalenga mkati mwa malo enaake, komanso kuwongolera kutentha kwa mkati, ukhondo, kuthamanga kwa mkati, liwiro la mpweya ndi kufalikira kwa mpweya, kugwedezeka kwa phokoso, kuunikira, ndi magetsi osasinthasintha mkati mwa malo enaake. Zotsatirazi zikufotokoza makamaka zinthu zinayi zofunika kuti ukhondo ukwaniritsidwe mu njira zoyeretsera zipinda zoyera.
1. Ukhondo wa mpweya
Kuti muwonetsetse kuti ukhondo wa mpweya ukukwaniritsa zofunikira, chofunikira kwambiri ndi momwe fyuluta yomaliza ya makina oyeretsera mpweya imagwirira ntchito komanso momwe imayikidwira. Fyuluta yomaliza ya makina oyeretsera mpweya nthawi zambiri imagwiritsa ntchito fyuluta ya hepa kapena fyuluta ya sub-hepa. Malinga ndi miyezo ya dziko, magwiridwe antchito a mafyuluta a hepa amagawidwa m'magulu anayi: Kalasi A ndi ≥99.9%, Kalasi B ndi ≥99.99%, Kalasi C ndi ≥99.999%, Kalasi D ndi (ya tinthu ≥0.1μm) ≥99.999% (yomwe imadziwikanso kuti mafyuluta a ultra-hepa); mafyuluta a sub-hepa ndi (ya tinthu ≥0.5μm) 95~99.9%.
2. Kapangidwe ka kayendedwe ka mpweya
Kapangidwe ka mpweya m'chipinda choyera n'kosiyana ndi ka chipinda chokhala ndi mpweya woziziritsa. Zimafunika kuti mpweya woyera kwambiri uperekedwe kaye kumalo ogwirira ntchito. Ntchito yake ndikuchepetsa ndikuchepetsa kuipitsidwa kwa zinthu zomwe zakonzedwa. Mabungwe osiyanasiyana oyendera mpweya ali ndi mawonekedwe awoawo ndi miyeso yawo: Kuyenda kolunjika kolunjika: Onsewa amatha kupeza mpweya wofanana pansi, kuthandizira kukonza zida zogwirira ntchito, kukhala ndi mphamvu yodziyeretsa yokha, komanso kungathandize malo wamba monga zipinda zoyera zaumwini. Njira zinayi zoperekera mpweya zilinso ndi zabwino ndi zoyipa zake: zosefera za hepa zophimbidwa bwino zili ndi zabwino zochepa komanso nthawi yayitali yosinthira zosefera, koma kapangidwe ka denga ndi kovuta ndipo mtengo wake ndi wokwera; zabwino ndi zoyipa zotumizira pamwamba pa zosefera za hepa zophimbidwa mbali ndi zotumizira pamwamba pa beseni lodzaza ndi mabowo ndi zosiyana ndi zotumizira pamwamba pa zosefera za hepa zophimbidwa bwino. Pakati pawo, kutumizira pamwamba pa beseni lodzaza ndi mabowo kumakhala ndi fumbi lochuluka mkati mwa beseni lotseguka pamene dongosolo silikugwira ntchito nthawi zonse, ndipo kusakonza bwino kudzakhudza ukhondo; Kutumiza pamwamba pa dense diffuser kumafuna wosanjikiza wosakaniza, kotero ndikoyenera zipinda zazitali zoyera zopitirira 4m, ndipo makhalidwe ake ndi ofanana ndi a kutumizira pamwamba pa mbale yodzaza mabowo; njira yobwezera mpweya ya mbale zokhala ndi ma grilles mbali zonse ziwiri ndi malo obwezera mpweya okonzedwa mofanana pansi pa makoma mbali zonse ziwiri ndi yoyenera zipinda zoyera zokhala ndi mtunda wochepera 6m mbali zonse ziwiri; malo obwezera mpweya pansi pa khoma la mbali imodzi ndi oyenera zipinda zoyera zokhala ndi mtunda wochepa pakati pa makoma (monga ≤2~3m). Kuyenda kolunjika kolunjika: malo oyamba ogwirira ntchito okha ndi omwe amafika pa ukhondo wa magawo 100. Mpweya ukayenda mbali inayo, kuchuluka kwa fumbi kumawonjezeka pang'onopang'ono. Chifukwa chake, ndikoyenera zipinda zoyera zokhala ndi zofunikira zosiyanasiyana za ukhondo panjira yomweyo. Kugawa kwa ma filter a hepa pakhoma lopereka mpweya kumatha kuchepetsa kugwiritsa ntchito ma filter a hepa ndikusunga ndalama zoyambira, koma pali ma eddies m'madera am'deralo. Kuyenda kwa mpweya wovuta: Makhalidwe a kutumizira pamwamba kwa ma orifice plates ndi kutumizira pamwamba kwa ma diffuser okhuthala ndi ofanana ndi omwe atchulidwa pamwambapa. Ubwino wopereka zinthu m'mbali ndi wosavuta kukonza mapaipi, wopanda ukadaulo, wotsika mtengo, komanso wothandiza kukonzanso mafakitale akale. Zoyipa zake ndi zakuti liwiro la mphepo pamalo ogwirira ntchito ndi lalikulu, ndipo kuchuluka kwa fumbi kumbali ya mphepo ndi kwakukulu kuposa kumbali ya mphepo. Kupereka kwapamwamba kwa malo otulutsira zinthu za hepa kuli ndi ubwino wa dongosolo losavuta, palibe mapaipi kumbuyo kwa fyuluta ya hepa, komanso mpweya woyera womwe umaperekedwa mwachindunji kumalo ogwirira ntchito, koma mpweya woyera umafalikira pang'onopang'ono ndipo mpweya womwe uli pamalo ogwirira ntchito umakhala wofanana. Komabe, pamene malo ambiri otulutsira mpweya amakonzedwa mofanana kapena malo otulutsira zinthu za hepa okhala ndi ma diffuser agwiritsidwa ntchito, mpweya womwe uli pamalo ogwirira ntchito ungapangidwenso kukhala wofanana. Komabe, pamene dongosolo silikuyenda mosalekeza, diffuser imakhala ndi fumbi lochuluka.
3. Kuchuluka kwa mpweya kapena liwiro la mpweya
Kuchuluka kokwanira kwa mpweya wopumira ndiko kuchepetsa ndikuchotsa mpweya wodetsedwa m'nyumba. Malinga ndi zofunikira zosiyanasiyana zaukhondo, kutalika konse kwa chipinda choyera kuli kokwera, kuchuluka kwa mpweya wopumira kuyenera kuwonjezeredwa moyenera. Pakati pawo, kuchuluka kwa mpweya wopumira m'chipinda choyera cha 1 miliyoni kumaganiziridwa malinga ndi dongosolo la chipinda choyera choyera kwambiri, ndipo zina zonse zimaganiziridwa malinga ndi dongosolo la chipinda choyera choyera kwambiri; pamene zosefera za hepa za chipinda choyera cha kalasi 100,000 zili m'chipinda cha makina kapena zosefera za sub-hepa zikugwiritsidwa ntchito kumapeto kwa dongosolo, kuchuluka kwa mpweya wopumira kumatha kuwonjezeredwa moyenera ndi 10% mpaka 20%.
4. Kusiyana kwa kuthamanga kwa mpweya
Kusunga mphamvu inayake yabwino m'chipinda choyera ndi chimodzi mwa zinthu zofunika kwambiri kuti chipinda choyera chisadetsedwe kapena kuchepetsedwa kuti chikhale ndi ukhondo wokonzedwa. Ngakhale m'chipinda choyera chopanda mphamvu, chiyenera kukhala ndi chipinda chapafupi kapena chipinda chokhala ndi ukhondo wosachepera mlingo wake kuti chikhale ndi mphamvu inayake yabwino, kuti ukhondo wa chipinda choyera chopanda mphamvu ukhalebe wabwino. Mphamvu yabwino ya chipinda choyera imatanthauza mtengo pamene mphamvu yamkati yosasunthika imakhala yayikulu kuposa mphamvu yakunja yosasunthika pamene zitseko ndi mawindo onse atsekedwa. Izi zimachitika mwa njira yomwe mphamvu ya mpweya yoyeretsera imakhala yayikulu kuposa mphamvu ya mpweya wobwerera ndi mphamvu ya mpweya wotuluka. Pofuna kutsimikizira mphamvu yabwino ya mpweya m'chipinda choyera, ndi bwino kulumikiza mpweya wobwerera, mpweya wobwerera ndi mafani otulutsa utsi. Dongosolo likayatsidwa, fan yoperekera imayatsidwa kaye, kenako fan yobwezera ndi fan yoperekera utsi imayatsidwa; dongosolo likayatsidwa, fan yoperekera utsi imazimitsidwa kaye, kenako fan yobwezera ndi fan yoperekera utsi imazimitsidwa kuti chipinda choyera chisadetsedwe pamene dongosolo likuyatsidwa ndi kuzimitsidwa. Kuchuluka kwa mpweya wofunikira kuti chipinda choyera chikhale ndi mphamvu yokwanira kumatsimikiziridwa makamaka ndi kulimba kwa kapangidwe kosamalira. Poyamba kumanga zipinda zoyera ku China, chifukwa cha kulimba kochepa kwa kapangidwe kotchingira, zidatenga nthawi 2-6 pa ola limodzi kuti mpweya ukhale ndi mphamvu yokwanira ya ≥5Pa; pakadali pano, kulimba kwa kapangidwe kosamalira kwasintha kwambiri, ndipo zimangotenga nthawi 1-2 pa ola limodzi kuti mpweya ukhale ndi mphamvu yofanana; zimangotenga nthawi 2-3 pa ola limodzi kuti mpweya ukhale ndi mphamvu yokwanira ya ≥10Pa. Mafotokozedwe a kapangidwe ka dziko lonse amanena kuti kusiyana kwa kuthamanga kwa mpweya pakati pa zipinda zoyera za milingo yosiyanasiyana komanso pakati pa malo oyera ndi malo osayera sikuyenera kukhala kochepera 0.5mmH2O (~5Pa), ndipo kusiyana kwa kuthamanga kwa mpweya pakati pa malo oyera ndi akunja sikuyenera kukhala kochepera 1.0mmH2O (~10Pa).
