Njira yoyeretsera fin heat exchanger

Kuyeretsa zotenthetsera zotenthetsera ndi zida zina kwakhala chinthu chofunikira komanso chofunikira kwambiri pakupangira mafakitale, makamaka m'mafakitale amafuta amafuta ndi mafuta.Kodi zifukwa ndi njira zofunika zogwirira ntchito zotsuka zotenthetsera kutentha ndi ziti?Ndiroleni ndikufotokozereni.

Popanga mafakitale oyeretsera mankhwala, pazifukwa zambiri, kupaka mafuta ambiri, dothi lamafuta, sikelo, matope, zinthu zowononga, polima, bowa, ndi zina zambiri zidzapangidwa mu fin heat exchanger zida ndi payipi.,smonga algae ndi matope.Dothi lotsatila lidzapangitsa kuti zida ndi mapaipi alephereke, ndipo zokolola za chipangizocho zidzachepa, ndipo kugwiritsa ntchito mphamvu ndi ndalama zakuthupi kudzakwera.Kuwonongeka kwachuma, ngakhale ngozi zopanga zopanga zitha kuchitika.

Nthawi zambiri pamakhala njira ziwiri zoyeretsera m'mafakitale poyeretsa zotenthetsera zotenthetsera: kuyeretsa mankhwala ndi kuyeretsa jeti lamadzi mothamanga kwambiri.Koma kwa nthawi yayitali, njira zoyeretsera zachikhalidwe ndi njira zochizira, monga njira zamakina, madzi othamanga kwambiri, kuyeretsa mankhwala (pickling), kuletsa mamba, ndi zina zotere, sizingathetse vutoli ndipo zitha kuwononga kwambiri zida zokha, thupi la munthu ndi chilengedwe.Ndi chitukuko chofulumira chamakampani amakono, kugwiritsa ntchito madzi ozizira sikungowonjezera, komanso kuchuluka komwe kulipo pazida zazikulu zosinthira zozungulira sikungathe kutsukidwa mwasayansi, zomwe zimapangitsa kugwiritsa ntchito mphamvu komanso kuwonongeka kwa chilengedwe, ndikuchepetsa magwiridwe antchito.Popanga mafakitale oyeretsera mankhwala, pazifukwa zambiri, kupaka mafuta ambiri, dothi lamafuta, sikelo, matope, zinthu zowononga, polima, bowa, ndi zina zambiri zidzapangidwa mu fin heat exchanger zida ndi payipi.,monga algae ndi matope.Dothi lotsatila lidzapangitsa kuti zida ndi mapaipi alephereke, ndipo zokolola za chipangizocho zidzachepa, ndipo kugwiritsa ntchito mphamvu ndi ndalama zakuthupi kudzakwera.Kuwonongeka kwachuma, ngakhale ngozi zopanga zopanga zitha kuchitika.

Njira zofunika kwambiri zoyeretsera kutentha kwa fin ndi:

1. Kutsitsa ndi kuyeretsa.Onjezani chotsitsa chokonzekera ndi choyeretsera molingana ndi madzi ozungulira mu thanki yoyeretsera poyeretsa ndi kutsitsa.Dziwani kuchuluka kwa mankhwala molingana ndi nthawi yoyeretsa komanso kuchuluka kwa sikelo.Mukaonetsetsa kuti masikelo onse ayeretsedwa, pitirizani ku njira yotsatira yoyeretsera.
2. Muzimutsuka ndi madzi oyera.Mukalumikiza zida zoyeretsera ku boiler, yeretsani ndi madzi oyera kwa mphindi 10, yang'anani momwe dongosololi lilili, fufuzani ngati pali kutayikira, ndikutsuka dzimbiri loyandama nthawi imodzi.
3. Kuyeretsa anti-corrosion.Onjezani chovulira pamwamba ndi chotulutsa pang'onopang'ono molingana ndi madzi ozungulira a thanki yoyeretsera ndikuyeretsani kwa mphindi 20 kuti mulekanitse sikelo ku magawo oyeretsedwa.
4. Kuchiza ❖ kuyanika mankhwala.Onjezani passivation ❖ ❖ ❖ ❖ ❖ ❖ ❖ Onjezani ❖ kuyanika (passivation coating agent) kuti muchepetse dzimbiri komanso dzimbiri la mapaipi ndi zinthu zina.
