Uma uzwa 'i-denitrification nozzle', abantu abaningi ngokushesha bafanekisela ikhanda elifuthayo elilula, mhlawumbe indiza ewubukhazikhazi. Lowo umbono oyiphutha wokuqala. Ezinhlelweni ze-SCR, akukhona nje ngokufafaza i-urea; kumayelana nokudala i-spectrum yamaconsi afanele, ukusatshalaliswa, kanye nokungena endaweni eshisa kakhulu, enesivinini esiphezulu segesi yoflue. Kwenze kube okungalungile, futhi ubheke isiliphu se-ammonia, ukuhlambalaza, noma ukusabela okungaphelele. Ngike ngabona izitshalo zisebenzisa imali eshisiwe kuma-catalyst ukuze ukusebenza kuvinjwe ukuhlanganiswa komjovo oklanywe kabi noma owenziwe. I-nozzle iyisixhumi esibonakalayo esibalulekile phakathi kwe-ejenti yokunciphisa kanye nenqubo, futhi ukwethembeka kwayo kuvame ukuxhomeka ku-Foundry kanye nomshini ngemuva kwayo.
Inselele Eyinhloko: Impahla kanye Nejometri Ngaphansi Komlilo
Ake sikhulume ngemvelo. Ngokuvamile sibhekene namazinga okushisa akwazi ukushwibeka, kanye nengxube egqwalayo yezinto eziphuma ku-ammonia kanye nomlotha ondizayo. I-316 engagqwali evamile ingase iyisike isikhashana kwezinye izimo, kodwa ekusetheni okuqinile, ikakhulukazi ngothuli oluningi oluningi noma izinga lokushisa eliphakeme, ubona ukuguguleka okusheshayo noma ukugqwala kwengcindezi kuqhekeka imbobo. Yilapho ukukhetha kwezinto ezibonakalayo kuba ngokoqobo. Akukhona nje ukukhetha kukhathalogi; kumayelana nokuqonda ukwakheka kwegesi ewuketshezi. Ngikhumbula iphrojekthi yesikhungo sokulahla imfucuza kuya kumandla lapho amabhobhothi okuqala, enziwe nge-austenitic engagqwali evamile, enza imifantu emincane phakathi nezinyanga. Ukwehluleka kwakungeyona into emangalisayo; kwaba ukwanda kancane kancane kokushelela kanye nokusatshalaliswa okungalingani okwathatha isikhathi ukuxilonga kubuyele ku-nozzle material uqobo.
Yilapho izinkampani ezinokuhlangenwe nakho okujulile kwempahla ziba usizo olukhulu. Ngicabanga ngomphakeli onjengaye I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngamashumi amathathu eminyaka ekulingiseni nasekukhiqizeni imishini, abagcini nje ngokuthatha ama-oda. Isizinda sabo sesikhunta segobolondo kanye nokusakazwa kokutshalwa kwezimali kwama-alloys akhethekile afana nalawo asuselwa ku-nickel kanye nasekelwe ku-cobalt ahambisana ngqo. Ngombhobho we-denitrification, umzimba we-Inconel 625 wokutshala imali unganikeza umjikelezo wempilo ohluke ngokuphelele uma uqhathaniswa nocezu olufakwe ngomshini olusuka esitokisini sebha evamile, ikakhulukazi mayelana nesakhiwo sokusanhlamvu nokumelana nokushisa. Umehluko usemininingwaneni yenqubo.
I-geometry ingesinye isilo. Indlela yokugeleza yangaphakathi, i-engeli yesifutho, i-orifice finish—lezi akubona nje ubukhulu be-CAD. Ukuchezuka kancane ku-taper eholela ku-orifice kungabangela i-cavitation, kulimaze umlomo wombhobho futhi konakalise iphethini yesifutho. Ukubekezelelana ngomshini kuyinkosi. Kudinga ikhono le-CNC elinembayo eliphezulu, kodwa futhi nokuqonda ukuthi le ngxenye ayiwona umjaho othwalayo; idinga ukunemba lapho ibala khona (i-orifice, isihlalo) kanye nokuqina kwenye indawo. Ngike ngaba nama-prototypes abukeka kahle kakhulu emdwebeni kodwa, lapho ehlolwa ebhentshini lokugeleza okubandayo, abonisa isifutho se-asymmetric. Umlandu? Cishe uphawu lwethuluzi olungabonakali ngaphakathi kwesiteshi sokuphakelayo oluphazamise ukugeleza kwe-laminar. Kuthathe isikhathi nethimba lemishini ukulungisa indlela yamathuluzi nokuqedela ukulandelana.
Ukusuka ekudwebeni kuya ku-Duct: I-Integration Headache
Ngisho nombhobho owenziwe ngokuphelele muhle kuphela njengokufakwa kwawo. I-flange ekhuphukayo, ukunwetshwa kokushisa okushisayo kungahambisani nodonga lwamapayipi, ukuvala - lezi izinto ezingokoqobo zensimu. Ukwengamela okukodwa okujwayelekile akubalwa ngokukhula okushisayo kwe-lance noma i-multifold. Ukufakwa okuqinile kungaholela ekucindezelekeni okukhulu emzimbeni we-nozzle, ukuqhekeka ama-welds noma ukuhlanekezela ukuqondanisa. Lokhu sikufunde kanzima ekubuyiseleni imali kusenesikhathi. Imibhobho yayilungile, kodwa abakaki abaqinile esibaklamile babengakuvumeli ukunyakaza kwamapayipi phakathi nemijikelezo yokushisa. Umphumela: izinwele ziyaqhekeka ezintanyeni zokushisela ngemva kokuqala okumbalwa. Ukulungiswa kwaba ushintsho olulula kodwa olubalulekile ekwakhiweni kosekelo oluntantayo.
Omunye umniningwane osebenzayo ukufinyeleleka. Emgudwini ominyene, uwuhlola kanjani noma uwushintsha kanjani umlomo wombhobho? Ukuxhumanisa okunqamula ngokushesha kuzwakala kukuhle ngokombono, kodwa engeza amaphuzu avuzayo angaba mkhulu. Ngezinye izikhathi uxhumano olulula olunezintambo ezine-high-temperature thread sealant lunokwethenjelwa kakhulu, uma uklama isikhala se-wrench. Ngincamela amadizayini avumela ukususwa ngaphandle kwepayipi ngaphandle kokuvala sonke isigaba, kodwa lokho akwenzeki ngaso sonke isikhathi. Kuwukuhwebelana phakathi kokulungiswa kalula nokuba yinkimbinkimbi kwesistimu.
Bese kuba nombuzo wemidiya ye-atomization. Isizwa umoya noma i-hydraulic? Kumasistimu amancane noma lapho umoya ocindezelwe utholakala kalula, ukusizwa komoya kunganikeza i-atomization kakhudlwana. Kodwa wengeza olunye uhlelo—imigqa yomoya, izihlungi, abalawuli. Ezitshalweni ezinkulu zamandla, i-hydraulic (usebenzisa isisombululo se-urea enengcindezi ephezulu ngokwayo) ivame ukuba lula. Inketho ithinta ngokuqondile umklamo wangaphakathi wombhobho. Umbhobho osizwa umoya unejiyomethri yangaphakathi ehluke ngokuphelele yokuxuba uketshezi olubili. Awukwazi ukuvele ushintshe uhlobo olulodwa ulufake kolunye ngaphandle kokwenza kabusha igridi yomjovo.
I-Case in Point: I-Alloy Shift
Isibonelo esiphathekayo esinginamathelayo sibandakanya ukuthuthukiswa kwebhoyela ebaselwa ngamalahle. Owokuqala ama-nozzles we-denitrification bekuyi-310S ejwayelekile engenabala. Ukusebenza bekulungile, kodwa izikhawu zokunakekela bezimfushane kunalokho obekulindelekile ngenxa yokuguguleka kwethiphu. Iklayenti belifuna ukunweba isikhathi sokusebenza. Sibheke idatha: izinga lokushisa endaweni yomjovo lalihlala lisezingeni eliphezulu lika-310S, futhi umlotha wempukane wawuqhuma ngokulingene.
Sisebenze ne-Foundry—QSY efika engqondweni njengoba bephethe lezi zinguquko ezibonakalayo—ukwenza isibonelo sesethi yamabhomu kusetshenziswa ingxubevange esekelwe ku-nickel ngokufaka utshalomali. Umgomo wawungekhona nje ukushintsha izinto; sithathe ithuba lokulungisa i-geometry yangaphakathi ngokusekelwe ekulingiseni kokugeleza ukuze sinciphise izindawo zokucindezela okuphansi lapho i-cavitation ingaqala khona. Ukukhishwa kwemishini kwangemuva komshini kwakubalulekile ukuze kugcinwe ukuphela kwendawo esiteshini sokuphakela kwe-capillary.
Umphumela awubanga ukweqa kokusebenza okuyisimangaliso, kodwa ukuthuthuka okuqinile, okuthembekile. Ama-nozzles amasha akhombisa ukuguga okungatheni ngemuva kwesikhathi amadala azodinga ukubhekwa. I-ROI yayisesikhathini esincishisiwe kanye nengozi ephansi yokwehluleka okungahleliwe. Okubalulekile kwaba indlela edidiyelwe: isayensi yezinto ezibonakalayo (ukukhetha ingxubevange efanele yendawo ethile), ukukhiqizwa okunembayo (ukufeza inhloso yokuklama), nolwazi lokufaka olusebenzayo. Ungathola abahlinzeki abasebenzisa izingxenye zomshini nje, kodwa ezingxenyeni ezingaphansi kwalolu hlobo lokucindezeleka okushisayo namakhemikhali, umlando we-Foundry ubalulekile. Isipiliyoni sesikhathi eside senkampani sokusakaza ama-alloys asebenza kahle kakhulu, njengalokhu okuphawulwe kukho https://www.tsingtaocnc.com, ngokuvamile ihumusha izeluleko ezingcono mayelana nokuziphatha okubonakalayo kanye nokuba nokwenzeka kokukhiqiza kwalezi zingxenye ezibalulekile.
Ngale KweNozzle: Ukucabanga Kwesistimu
Kuyalinga ukugxila ku-nozzle njengengxenye ezimele, kodwa akusizi ngaphandle kokucabangela lonke uhlaka lwegridi yomjovo. Isikhala, i-engeli ehlobene nokugeleza kwegesi, ibanga lokuya ebusweni be-catalyst—le mingcele ibeka ukuxubana kokuqala. Umbhobho omuhle endaweni engalungile uwukumosha. Sivame ukusebenzisa ukumodela kwe-CFD njengomhlahlandlela, kodwa akukho okungathatha indawo yokushuna kwenkambu ngesikhathi sokusebenza. Ulungisa amazinga okugeleza nezingcindezi ngenkathi ukala ukusatshalaliswa kwe-ammonia endaweni yokufaka i-catalyst. Kwesinye isikhathi, uthola ukuthi ukulungiswa okuncane kokugeleza kwenozi eyodwa kunomthelela wokwehla ekusabalaleni kukonke.
Yilapho i-modularity kumklamo ohlukahlukene we-nozzle kusiza khona. Uma i-nozzle ngayinye ikulayini wokuphakelayo olungisekayo ngamunye (ngaphakathi kwesizathu), inikeza onjiniyela benkundla ithuluzi elinamandla lokuthuthukisa. Ngibone amasistimu lapho avale khona yonke into phansi ngokuqinile ukuze wonge ezindlekweni zokufaka, bese ngichitha izikhathi eziyishumi kamuva ngizama ukulungisa izinkinga zokusabalalisa ngokulungiswa kwe-catalyst layer noma ngokugijima ngaphezu kwezilinganiso ezidingekayo ze-ammonia-to-NOx.
Okokugcina, ungakunaki okujwayelekile: ukuhlunga. Isixazululo se-urea, ngisho noma sisezingeni eliphezulu, singaba nezinhlayiya noma zicwebezele. Ucezu oluncane lwemfucumfucu lungavimba imbobo yomlomo. Ukuhlunga okuqinile, okunezigaba eziningi ukuya phezulu kwegridi yomjovo akuxoxiswana ngakho. Inqubomgomo yomshwalense eshibhile yalo lonke uhlelo lwe-SCR. Bhangqa lokho nombhobho oklanywe kahle onekhono lokuzihlanza (njengendlela ethile yokugeleza yangaphakathi evimbela ukwakheka kwediphozithi), futhi uthuthukisa kakhulu ukuthembeka kokusebenza.
Ukuyigoqa: Ingxenye Yomphumela
Ngakho, i i-denitrification nozzle. Kuyingxenye encane enomthwalo wemfanelo omkhulu. Ukuyicacisa kudinga ukudlulela ngale kwento elula bese ufutha i-angle call-out. Idinga ingxoxo mayelana nemvilophu yangempela yokusebenza, uphethiloli, ukulayishwa kothuli, izinsiza ezitholakalayo ze-atomization, kanye nefilosofi yokulungisa. Ukukhethwa kozakwethu bokukhiqiza kubaluleke ngokufanayo—udinga othile okuqondayo kokubili i-metallurgy ukuze uqine kanye nokunemba komshini wokusebenza.
Kulo mkhakha, ukwehluleka akuvamile ukuqhuma okuyinhlekelele; ziwukushiswa kancane kokungasebenzi kahle - ukwanda kokusetshenziswa kwe-ammonia, ubuthi obangela ubuthi, izinkinga zokwehla kwengcindezi. Babiza imali nsuku zonke. Ukuthola umjovo ngendlela efanele, kuqala ngombhobho oqinile, okhule kahle, kusetha isisekelo sakho konke ukusabela kwe-SCR. Ingenye yalezo zingxenye lapho ukutshalwa kwezimali kwangaphambili ekwakhiweni okufanele nokukhiqizwa kwekhwalithi kubuyisela buthule kodwa ngokungaguquki phakathi neminyaka yokusebenza. Uyeka ukucabanga ngakho, futhi lokho ukuncoma okungcono kakhulu ucezu lwemishini yenqubo engaluthola.
Uma sibheka emuva, amaphrojekthi ahamba kahle kakhulu yilawo lapho singaphathi khona uhlelo lomjovo njengokuthengwa kwempahla, kodwa njengohlelo oluncane oludidiyelwe. Lokho bekusho ukubandakanya abahlinzeki abanokufakwa kwezicelo kanye nokujula kokukhiqiza ekuqaleni kwesigaba sokuklama, hhayi nje ukuthumela imidwebo eqediwe ukuze icaphune. Kwenza umehluko.
