I-Silicon Carbide FGD Nozzle ohlelweni lwe-Limestone wet desulfurization

I-Flue Gas Desulfurization (FGD) Absorber Nozzles
Ukususwa kwama-sulphur oxides, avame ukubizwa ngokuthi i-SOx, kusuka kumagesi akhipha umoya usebenzisa i-alkali reagent, njenge-limestone slurry emanzi.

Uma izibaseli ezimbiwa phansi zisetshenziswa ezinqubweni zomlilo ukuze kuqhutshwe amabhayela, izithando zomlilo, noma ezinye izinto zokusebenza zinamandla okukhulula i-SO2 noma i-SO3 njengengxenye yegesi ephumayo. Lawa ma-sulfur oxides asabela kalula nezinye izakhi ukuze akhe isakhi esiyingozi njenge-sulfuric acid futhi anamandla okuba nomthelela omubi empilweni yomuntu kanye nemvelo. Ngenxa yale miphumela engaba khona, ukulawulwa kwalesi sithako kumagesi aphuma ku-flue kuyingxenye ebalulekile yezitshalo zokuphehla amandla ngamalahle nezinye izinhlelo zokusebenza zezimboni.

Ngenxa yokuguguleka komhlabathi, ukuxhunywa, nokukhathazeka ngokwakha, enye yezinhlelo ezinokwethenjelwa kakhulu zokulawula lokhu kukhishelwa yinqubo evulekile yomthombo we-wet flue gas desulfurization (FGD) esebenzisa i-limestone, i-hydrated lime, amanzi olwandle, noma esinye isixazululo se-alkaline. Iziduli zokufutha ziyakwazi ukusabalalisa ngempumelelo nangokuthembekile la ma-slurries emibhoshongweni yokumunca. Ngokwenza amaphethini afanayo amaconsi anosayizi ofanele, lawa mabhomu ayakwazi ukudala ngempumelelo indawo engaphezulu edingekayo ukuze amunce kahle kuyilapho enciphisa ukugxiliswa kwesisombululo sokukhuhla kugesi ephuma amanzi.

Ukukhetha i-FGD Absorber Nozzle:
Izici ezibalulekile okufanele zicatshangelwe:

Ukuxubha ukuminyana kwemidiya kanye ne-viscosity
Usayizi weconsi odingekayo
Usayizi wamaconsi ofanele ubalulekile ukuze kuqinisekiswe amazinga afanele wokumunca
Izinto zeNozzle
Njengoba i-flue gas ivame ukugqwala futhi uketshezi lokukhuhla kuvame ukuba wudaka olunokuqukethwe okuqinile okuphezulu kanye nezinto ezilimazayo, ukukhetha ukugqwala okufanele kanye nezinto ezimelana nokugqoka kubalulekile.
Ukumelana ne-Nozzle clog
Njengoba uketshezi lokukhuhla kuvame ukuba ludaka olunokuqukethwe okuqinile okuphezulu, ukukhethwa kwembobo maqondana nokumelana nokuvala kubalulekile.
Iphethini ye-nozzle spray kanye nokubekwa
Ukuze kuqinisekiswe ukumuncwa okufanele okuphelele kokugeleza kwegesi ngaphandle kokudlula futhi isikhathi esanele sokuhlala sibalulekile.
Usayizi woxhumano lwe-Nozzle nohlobo
Amazinga okugeleza kwamanzi okukhuhla adingekayo
Ukwehla kwengcindezi okutholakalayo (∆P) ku-nozzle
∆P = nikeza ingcindezi endaweni yokungena emlonyeni – cindezela ingcindezi ngaphandle kwenozzle
Onjiniyela bethu abanolwazi bangasiza ekunqumeni ukuthi iyiphi i-nozzle ezosebenza njengoba kudingekile ngemininingwane yedizayini yakho
Ukusetshenziswa Okujwayelekile KweNozzle ye-FGD Absorber Nezimboni:
Amalahle nezinye izimboni zamandla kaphethiloli
Izihlungi ze-Petroleum
Izishisi zemfucuza zikamasipala
Iziko likasimende
Izincibilikisi zensimbi

I-SiC Material Datasheet

Imibhobho ye-SNBSC ne-RBSC:

I-Silicon Nitride Bonded Silicon Carbide (SNBSC):
Impahla ye-ceramic enokumelana okuhle kakhulu nokuguguleka nokugqwala. Imoduli ephansi yokuqhekeka (MOR) nokungamelani kahle nomthelela kukhawulela okokusebenza kumadizayini alula anesakhiwo esinezingxenye ezisindayo zodonga. I-SNBSC ivamise ukusetshenziselwa ikhoni engenalutho, imibhobho ye-whirl tangential.
I-Reaction Bonded Silicon Carbide (RBSC/SiSiC):
Impahla ye-ceramic enokumelana okuhle kakhulu nokuguguleka nokugqwala. Ngoba i-MOR ye-RBSC iyizikhathi ezingu-5-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi.
I-RBSC isengozini yokwehluleka, ngoba zenziwe nge-ceramic brittle. Lapho ama-nozzles ehluleka, cishe azohluleka ngenxa yokuphuka. Lokhu kuphuka kungabangelwa izinqubo zokufaka ezinephutha, ama-pressure spikes (isando samanzi) ngesikhathi sokuqalisa, ukuzama ukuhlanza imibhobho exhunyiwe noma eminye imisebenzi yokulungisa evamile.

I-Shandong Zhongpeng Special Ceramics Co., Ltd ingesinye sezixazululo ezintsha ze-silicon carbide zobumba eChina. I-ceramic yobuchwepheshe ye-SiC: Ubulukhuni be-Moh buyi-9 (ukuqina kwe-Moh entsha yi-13), enokumelana okuhle nokuguguleka nokugqwala, ukuhuzuka okuhle kakhulu – ukumelana ne-oxidation. Impilo yesevisi yomkhiqizo we-SiC iyinde izikhathi ezi-4 kuya kwezi-5 kune-alumina material engu-92%. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi. Inqubo yekhotheshini iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ingeyesibili. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisele izinhliziyo zethu emphakathini.
