Boiler ya mafakitale nthawi zambiri amagwiritsidwa ntchito pamagetsi amagetsi, mankhwala, makampani opepuka ndi mafakitale ena, ndipo amagwiritsidwa ntchito kwambiri m'miyoyo ndi mabungwe. Pamene owonera sakugwiritsa ntchito, mpweya wambiri umayenda m'madzi a boiler's. Ngakhale obowola amene amatulutsa madzi, pali filimu yamadzi pachitsulo, ndipo mpweya wake udzasungunuka mkati mwake, zomwe zimapangitsa kuti mpweya wa oxygen ukhale. Pakakhala pamlingo wamchere pachitsulo cha boaleler, chomwe chingasungunuke mu filimu yamadzi, kuphukira kumeneku kudzakhala kwakukulu. Kuchita kumawonetsa kuti kutukula kwakukulu mu boilers kumapangidwa kwambiri panthawi yotseka ndikupitilizabe pakugwiritsa ntchito. Chifukwa chake, kutenga njira zoyenera zotchinga panthawi yotsekereza ndikofunikira kwambiri kuti mupewe kuwonongedwa kwa boiler, onetsetsani kuti ntchito yotetezeka, ndikuwonjezera moyo wa boiler.
Pali njira zambiri zopewera kutsekeka kwa boilerdown, komwe kumatha kugawidwa m'magulu awiri: njira yowuma komanso njira yonyowa.
1. Njira yowuma
1. Njira ya Desiccant
Tekinolojeni ya desiccant imatanthawuza kuti pambuyo pa boiler yayimitsidwa, pomwe kutentha kwamadzi kumatsika 100 ~ 12 ° Ch, madzi onse adzachotsedwa, ndipo kutentha kwa chivundikiro mu ng'anjoyo kudzaugwiritsa ntchito kuti muume yachitsulo; Nthawi yomweyo, sikelo yokhazikika mu kayendedwe kamadzi kwa boiler idzachotsedwa, slag ya madzi ndi zinthu zina zimatulutsidwa. Kutayika kumalowetsedwa mu boiler kuti ikhale yopuma kuti isawonongeke. Zodziwika bwino zimaphatikizira: CACL2, CAO, ndi silika gel.
Kuyika kwa Desiccant: Gawani mankhwalawo m'madzi angapo ndikuwayika pama boilers osiyanasiyana. Pakadali pano, mavuvu onse ndi mavu amadzi ayenera kutsekedwa kuti aletse mpweya wakunja.
Zoyipa: Njira iyi ndi ya hygroscopic yokha. Iyenera kuyesedwa mutatha kuwonjezera deta. Nthawi zonse samalani ndi ma dechiquesnce a mankhwalawo. Ngati chinyengo chimachitika, m'malo mwake.
2. Njira yowuma
Njirayi ndikukhetsa madzi pomwe kutentha kwa madzi kumadontho mpaka 100 ~ 120 ° C pomwe boiler C pomwe boiler watseka. Madzi athetsedwa, gwiritsani ntchito yotsalira mu ng'anjo kuphika kapena kuyambitsa mpweya wotentha mu ng'anjo kuti uume zamkati mwa boiler.
Zovuta: Njira iyi ndiyoyenera kuteteza ma boiler kwakanthawi kokonzanso.
3. Njira ya hydrogen yolipira
Njira yolipirira nitrogen ndikulipiritsa hydrogen kulowa m'madzi a boiler ndikukhalabe ndi nkhawa zina kuti mpweya usalowe. Popeza hydrogen ndi yosagwira komanso yopanda mphamvu, imatha kupewa kutsekeka kwa borelerdown.
Njira ndi iyi:Musanatseketse ng'anjoyo, kulumikiza mapaipi a nayitrogeni. Kupanikizika kwa ng'anjo kumatsikira mpaka 0,5, chitoliro cha hydrogen chimayamba kutumiza nayitrogeni kupita ku dorm ndi chuma kudzera m'mapaipisi osakhalitsa. Zofunikira: (1) Kuyera kwa nayitrogeni kuyenera kukhala pamwamba 99%. (2) Ng'ombe yopanda kanthu ikadzazidwa ndi nayitrogeni; Kupanikizika kwa nayitrogeni mu ng'anjo kuyenera kukhala pamwamba pa 0,5 kupanikizika. . . Ngati kumwa kwa nayitrogeni kumapezeka, kutayikira kuyenera kupezeka ndikuchotsedwa nthawi yomweyo.
Zovuta:Muyenera kulipira chisamaliro cha hydrogen chopanda ntchito, fufuzani nthawi tsiku lililonse, komanso kuthana ndi mavuto munthawi yake. Njirayi ndiyoyenera kuteteza boolers zomwe sizikugwira ntchito kwakanthawi kochepa.
4. Njira ya Ammoniam
Njira yodzaza ndi Ammonia ndikudzaza voliyumu yonse ya boiler ndi mpweya wa ammonia pambuyo pa boiler atatsekera ndipo madzi amasulidwa. Amoni amasungunuka mu kanema wamadzi pachachitsulo, ndikupanga filimu yoteteza kuvunda pachitsulo. Ammonia amathanso kuchepetsa kusungunuka kwa okosijeni m'mafilimu amadzi ndikupewa kutungunuka ndi mpweya wosungunuka.
Zovuta: Mukamagwiritsa ntchito njira yodzaza ammonia, zigawo zamkuwa ziyenera kuchotsedwa kuti zizikhala ndi ma ammonia mu boiler mu boiler.
5. Njira yokulunga
Pambuyo pa boiler yachoka mu ntchito, kukhetsa madzi, chotsani dothi, ndikuwumitsa chitsulo. Kenako ikani utoto wosanjikiza wotsutsa-corossion pa chitsulo kuti mupewe kututa kwa boiler. Utoto wotsutsa-corluon nthawi zambiri umapangidwa ndi ufa wakuda ndi mafuta injini mu gawo lina. Mukamakula, pamafunika kuti ziwalo zonse zomwe zitha kulumikizana ziyenera kunenedwa.
Zoyipa: Njirayi ndiyothandiza komanso yoyenera kukonza kwa nthawi yayitali kukonza; Komabe, zimakhala zovuta kugwira ntchito ndipo sikophweka kupaka makona, ma welld, ndi makoma owoneka bwino omwe amakonda kuwononga, chifukwa chake ndi koyenera kutetezedwa mwamphamvu.
2. Njira yonyowa
1. Njira ya Alkalinene Yalkaline:
Njirayi imagwiritsa ntchito njira yowonjezera alkali kuti mudzaze boiler ndi madzi omwe ali ndi kaphikidwe kazipatso. The Alkali yankho lomwe limagwiritsidwa ntchito ndi Naoh, Na3po4 kapena osakaniza awiriwa.
Zovuta: Chisamaliro chikuyenera kuthandizidwa kuti lizikhala yunifolomu lalkali ndende mu njira yothetsera, pokhazikitsa mtengo wa boiler, ndipo samalani ndi kuchuluka kwa kuchuluka kwa sikelo yochokera.
2. Njira yoteteza sodium sulfite
Sodium Sulfate ndi wopulumutsa wogwirizira yemwe amachita ndi mpweya wosungunuka m'madzi kuti apange sodium sulfate. Izi zimalepheretsa mawonekedwe achitsulo kuti asamuwonongedwe ndi mpweya wosungunuka. Kuphatikiza apo, njira yodzitetezera yothetsera vuto la ma trisdium phosphate ndi sodium nitrite ikhoza kugwiritsidwanso ntchito. Njirayi imatengera kuti madzi osakanizidwa awa amatha kupanga filimu yoteteza pa chitsulo kuti mupewe chilala chachitsulo.
Zovuta: Mukamagwiritsa ntchito njira yonyowa iyi iyenera kuthiridwa bwino ndipo kutsukidwa bwino musanayambe ng'anjo ya peonayo, ndipo madzi ayenera kuwonjezeredwanso.
3. Njira Yamoto
Njirayi imagwiritsidwa ntchito ngati nthawi yotseka ili mkati mwa masiku 10. Njira ndikuyika thanki yamadzi pamwamba pa Drum Smiy ndikulumikizani ndi chipongwe cha Steam ndi chitoliro. Wofatsa atayatsidwa, imadzaza madzi olakwika, ndipo thanki yambiri yamadzi imadzaza ndi madzi. Tanki yamadzi imayendetsedwa ndi nthunzi yakunja, kotero kuti madzi mu thanki yamadzi nthawi zonse amakhala ndi maboma.
Zovuta: Kuyambitsa njirayi ndikuti zimafunikira gwero lamphamvu lakunja kuti lizipereka nthunzi.
4. Njira yoteteza (yosunga) kugwiritsa ntchito majekiti opanga mafilimu
Njira iyi ndikuwonjezera othandizira a amine omwe amapangira matenthedwe opangira matenthedwe pomwe kupanikizika kwa boaler ndi kutentha kutsika koyenera panthawi yotseka yaint. Othandizira amazungulira ndi nthunzi ndi madzi, ndi mamolekyulu othandizira ali ndi ma adsorbed olimba pa chitsulo ndi omangika motsatizana. Makonzedwe amapangika moleclar osanjikiza ndi "chotchinga" kuti mupewe kusamuka kwa milandu ndi zinthu zowononga (mpweya) pachitsulo kuti mukwaniritse cholinga chopewa chitsulo.
Zovuta: Gawo lalikulu la wothandizirayo ndi loyera kwambiri la ma Alkanes ndi ma amting opanga mafilimu ozikidwa pa ocdecylamine. Poyerekeza ndi othandizira ena, ndizokwera mtengo kwambiri komanso kuvutitsa kuwongolera.
Njira zomwe zili pamwambazi ndizosavuta kugwira ntchito tsiku ndi tsiku ndipo zimagwiritsidwa ntchito ndi mafakitale ambiri ndi mabizinesi. Komabe, pochita opareshoni yeniyeni, kusankha njira yokonzanso njira mosiyananso chifukwa cha zifukwa zosiyanasiyana zosanjana ndi ng'anjoyo. Mukugwira ntchito yeniyeni, kusankha njira zoyenera kumatsata mfundo zotsatirazi:
1. Ng'ngayo ikatseka kwa miyezi yopitilira itatu, njira yopanda tanthauzo mu njira yowuma iyenera kugwiritsidwa ntchito.
2. Ng'ngayo ikatseka kwa miyezi 1-3, njira ya alkali ya alkali kapena njira ya sodium nitrium instiri ingagwiritsidwe ntchito.
3. Pambuyo pa boiler imayima kuthamanga, ngati zingayambike mkati mwa maola 24, njira yokhazikika ingagwiritsidwe ntchito. Njira iyi imatha kugwiritsidwanso ntchito kwa boilers yomwe imagwira ntchito pang'onopang'ono kapena osagwira ntchito mkati mwa sabata limodzi. Koma kupsinjika m'ng'anjo kuyenera kukhala kwakukulu kuposa kupanikizika kwa m'mlengalenga. Ngati kupsinjika kwapezeka kuti zitsike pang'ono, moto uyenera kuyamba kuwonjezera kukakamizidwa panthawi.
4. Pamene ogula asiya chifukwa chokonza, njira youma ingagwiritsidwe ntchito. Ngati palibe chifukwa kumasula madzi, njira yogwirira ntchito imagwiritsidwa ntchito. Ngati boiler mutatha kukonza sizingagwiritsidwe ntchito nthawi. Njira zovomerezeka zimayenera kutengedwa malinga ndi kutalika kwa ngongole.
