Izimo zezimboni ezinokhahlo azithetheleli izingxenye ezibuthakathaka. Ezimbonini zokucubungula amakhemikhali, amayunithi e-flue gas desulfurization, noma izindawo zokuhluza ezisogwini, izifeni ezijwayelekile ze-carbon-steel ziyehluleka phakathi nezinyanga—ukubhoboza, ukuqhekeka, ukudonsa ngaphansi komoya ogcwele i-chloride noma umhwamuko one-asidi. Umbuzo wangempela awukho uma ukugqwala kuzoshaya-kunjalo nini, kanye nokuthi kuzoletha isikhathi esingakanani ukuphumula, izindleko zokulungisa, kanye nobungozi bokuphepha. Yingakho onjiniyela e-Zibo Hongcheng Fan Co., Ltd. bayeka ukuklama abalandeli "abamelana nokugqwala ngokwanele". Bakha amafeni ensimbi engagqwali elwa nokugqwala aklanyelwe ukuyekethisa: 316L izindlu zensimbi engagqwali, shafts, ama-impeller, nezinsimbi; ama-seams ahlanganiswe ngokugcwele; izindawo ezingenalutho; kanye nokulinganisa okuguquguqukayo okugunyazwe ku-ISO 1940 G2.5. Hhayi njengenketho-kodwa njengesisekelo.
Kungani Insimbi Engagqwali Ingeyona Nje “Ingcono”—Ayikuxoxiswana ngayo Ezicelweni Ezibucayi
Sibone amaphethini amathathu okuhluleka ajwayelekile kuzilungiselelo ezigqwalile: okokuqala, ukugqwala kwe-galvanic lapho amafreyimu ensimbi ye-carbon athintana nama-impellers angenasici—akha ama-micro-currents adla amajoyinti e-weld. Okwesibili, ukugqwala kwemifantu ngaphakathi kwama-flange aboshiwe achayeke ku-condensate ne-sulphur dioxide. Okwesithathu, ukubola kwe-stress-corrosion ku-fan shafts ngaphansi komthwalo oshisayo ojikelezayo kanye nokuchayeka kwe-H₂S. Abalandeli abajwayelekile abane-epoxy-coated bavala lezi zinkinga—kuze kube yilapho bemboza ama-chips ngesikhathi sokulungiswa noma ukuhamba ngebhayisikili okushisayo, kuveza insimbi eluhlaza ngaphansi. Ifeni yensimbi engagqwali elwa nokugqwala iqeda imbangela: akukho ukumboza okonakaliswa, azikho izinsimbi ezingafani nezithandani, azikho izingibe zokugqwala ezifihliwe. E-Zibo Hongcheng, wonke amafeni we-FBD-Ⅱ ochungechunge olumiselwe isevisi yegesi yamalahle isebenzisa ama-ducting angu-316L angenamthungo kanye nama-impeller blades anobuncane bodonga obungu-2.5 mm—hhayi nje ukumelana nenkungu ye-asidi, kodwa ukumelana nezinhlayiya ezihugayo ngaphandle kokuncipha ngaphansi kokubekezela kwesakhiwo.
Ukusebenza Komhlaba Wangempela Kudinga Ukulolongwa Sonke Isinqumo Sedizayini
Abanye bangase baphikise insimbi engagqwali idlula umswakama opholile. Kodwa idatha yasensimini isitshela enye indaba. Embonini yamakhemikhali yaseShandong esebenza ngokuqhubekayo okungama-24/7, isiphephetha-moya esimbozwe nge-centrifugal sathatha izinyanga eziyi-14 ngaphambi kokuquleka okubangelwe yinhlekelele kusuka ekufudukeni kwe-chloride kugrisi. Indawo yayo yensimbi engagqwali elwa nokugqwala—ukugeleza komoya okufanayo (28,000 m³/h), ukucindezela okufanayo okumile (3,200 Pa), ukulinganisa kwemoto okufanayo (55 kW)—kusebenze izinyanga ezingu-47 ngokuvalwa okungahleliwe okungahleliwe. Kungani? Ngoba uZibo Hongcheng akashintshi nje ngezinto zokwakha. Bakha kabusha: izindlu ezinwetshiwe ezinezindebe ezimbili ezilinganiselwe zika-IP68; ama-labyrinth angathinteki ekwandisweni kwe-shaft; kanye namaphrofayili e-impeller blade alungiselelwe isivinini sethiphu ephansi-ukunciphisa ukuguguleka ngenkathi kugcinwa ukusebenza kahle. I-9-19 high-pressure Stainless Stainless blower yabo, esetshenziswa kabanzi njengabalandeli abaphambili be-boiler ezitshalweni ezishiswa nge-biomass, iletha ukusebenza kahle okuphezulu okungama-84.3% ku-1,450 rpm-hhayi naphezu kokumelana nokugqwala, kodwa ngenxa yesiyalo sokuklama okushisayo nemishini.
Ukwenza Ngokwezifiso Okusebenzayo-Hhayi Izimangalo Zokuthengisa Kuphela
“Ukwenziwa ngendlela oyifisayo” kusho okuncane ngaphandle kokuthi ithunyelwe ngesikhathi, ihlangabezana ne-spec, futhi isinde ekuthunyelweni. E-Zibo Hongcheng, ukwenza ngokwezifiso kuqala ngobunjiniyela bohlelo lokusebenza—hhayi amashidi okuthengisa. Lapho indawo yokuncibilikisa i-titanium idinga amafeni angaqhumi amelana nomhwamuko kasawoti oncibilikisiwe ongu-450°C, ithimba labo alizange lishintshe ngokuzenzakalelayo emibhalweni ejwayelekile. Babuyekeze imibiko yangempela yokwakhiwa kwegesi ephuma kugesi, ama-gradients afakwe kumephu ashisayo kuzo zonke izindlu zabalandeli, bakhetha i-Inconel 625 yamakhoni angenayo, bengeza izisekelo ezinejakhethi yamanzi, kanye nokusebenza okuqinisekisiwe kumshini wabo wokuhlola wangaphakathi ongu-1,200 kW—ukudlidliza kokulinganisa, ukukhuphuka kwezinga lokushisa, kanye nokuwohloka kwengcindezi ngaphezu kwamahora angu-72 ngaphansi komthwalo ofanisiwe. Ayikho inombolo yekhathalogi engaphandle kweshelufu. Cha "kungaphansi kokubuyekezwa konjiniyela." Okusanda kubhalwe phansi, okuphindaphindwayo, ukubulawa okufakazelwe yinkambu. Iphothifoliyo yabo yensimbi engagqwali ye-anti-corrosion fan ihlanganisa okuhlukile okungu-17 okunesitifiketi se-ATEX, i-IECEx, noma i-CCC-Mine—futhi iyunithi ngayinye ithunyelwa ngemibiko yokuhlolwa kwezinto ezilandelekayo (ama-MTR), izitifiketi zebhalansi eguqukayo, namajika okusebenza anomthwalo ogcwele osayinwe unjiniyela oyimishini obhalisiwe.
Ukuthembeka Ongakuqinisekisa—Ngaphambi Kokufakwa
Ukwethemba kuvela obala—hhayi izincwajana. Wonke umlandeli wensimbi engagqwali oqeda ukugqwala ovela eZibo Hongcheng udlula ezindaweni zokuhlola ezine eziyisibopho: ukuqinisekiswa kwempahla eluhlaza nge-spectrometer ye-XRF ephathwa ngesandla (iqinisekisa i-Mo ≥ 2.5%, Cr ≥ 16.5%, Ni ≥ 10.5%); ukuhlolwa kwe-dimensional kusetshenziswa izinto eziqinisekisiwe ze-CMM; ukuhlolwa okusebenzayo ku-110% isivinini esilinganiselwe imizuzu engu-30 ngokuqapha kokudlidliza kwesikhathi sangempela (<0.71 mm/s RMS ngesivinini sokusebenza); kanye nokuhlola kokuvuza kokugcina nge-helium mass spectrometry kuwo wonke ama-seams ashiselwe. Akukho okuthunyelwa ngaphandle kwedosi ledijithali elinekhodi ye-QR elixhumanisa namavidiyo okuhlola, izikena ze-MTR, namalogi okulinganisa. Yileyo ndlela ogwema ngayo iphutha lika-$120,000: ukufaka ifeni “engenasici” ukuze uthole i-baseplate ingu-304—hhayi u-316L—futhi kwehluleka ezinyangeni eziyisithupha eduze kwesikrufu se-chlorine.
Ukugeleza komoya ezimbonini akukhona okumayelana nokunyakaza komoya—kumayelana nokusekela ukuqhubeka kwenqubo, ukuvikela izisebenzi, nokugwema ukwehluleka okwehlayo. I-stainless steel anti-corrosion fan ayisona isikhungo sezindleko. Iwumugqa wokuqala wokuzivikela engcupheni yesistimu. I-Zibo Hongcheng Fan Co., Ltd. izakhela ukuze zingafinyeleli izindinganiso eziphansi—kodwa ukuze ziphile kunezisetshenziswa ezizihlinzekayo. Ngoba ezimweni ezinzima, ukuqina akuyona inketho. Iwukuphela kokucaciswa okubalulekile.
