Esithombeni esikhulu sokukhiqiza kwezimboni, kuhlale kukhona ezinye izinto ezincane ezenza imisebenzi ebalulekile buthule. I-nozzle ye-silicon carbide desulfurization "iqhawe elingemuva kwezigcawu" - ifihla embhoshongweni we-desulfurization wezitshalo zikagesi nezitshalo zensimbi, usuku nosuku "ihlanza" igesi yomoya yezimboni, ibambe i-sulfur dioxide eyingozi ngaphambi kokukhipha. Iyini isici esikhethekile sale divayisi enembile eyenziwe ngezinto ze-silicon carbide?
1, Kungani kufanele i-silicon carbide? 'Amathambo aqinile' ezintweni
Ukuqonda izinzuzo zeama-nozzles e-silicon carbide desulfurization, sidinga ukuqala “ngokwakheka” kwabo. I-Silicon carbide iyinto engaphili eyenziwe ngokwenziwa, enama-athomu ahlanganiswe yizibopho ze-covalent eziqine kakhulu ukuze kwakhiwe isakhiwo esizinzile esifana nedayimane. Lesi sakhiwo siyinika “amandla amakhulu” amathathu:
Imelana nokugqwala: Igesi yomoya ongcolile yezimboni ixutshwa nezinto ezigqwalisayo njenge-acid inkungu kanye ne-limestone slurry, futhi ama-nozzle ensimbi ajwayelekile maduze azogqwala futhi agcwale imigodi. I-silicon carbide inokumelana okuphezulu kakhulu ne-acid kanye ne-alkali kunezinsimbi, futhi ingagcina ubuqotho besakhiwo ngisho nangemva kokucwiliswa isikhathi eside ezindaweni ezigqwalayo kakhulu.
Ingamelana namazinga okushisa aphezulu: Izinga lokushisa legesi yomoya ngaphakathi kombhoshongo wokususa i-sulfurization livame ukufinyelela amakhulu ama-degree Celsius, futhi ngezinye izikhathi kungaba nomehluko omkhulu wokushisa ngenxa yokuqalisa nokuvala kwemishini. Ukuqina kokushisa kwe-silicon carbide kunamandla kakhulu, futhi akulula ukuqhekeka ngisho noma kwenzeka umthelela wokushisa okuphezulu ngokushesha. Isethembekile ngaphansi kwezimo zokushisa eziphakeme kakhulu.
Ingamelana nokuguguleka: Lapho i-slurry ye-desulfurization egeleza ngesivinini esikhulu idlula embotsheni, izoqhubeka nokuguguleka udonga lwangaphakathi. Ubulukhuni be-silicon carbide bulandela idayimane kuphela, futhi ingamelana kalula nalolu hlobo lokuguguleka. Isikhathi sayo sokusebenza siphindwe kaningana kune-nozzles ejwayelekile yepulasitiki noma yensimbi.
2, Akugcini nje ngokuthi 'kuqinile', kodwa futhi 'kuyi-booster' yokusebenza kahle kwe-desulfurization
Inani lama-nozzles e-silicon carbide desulfurization lidlula kakhulu “isikhathi eside”. Umklamo walo ufihla imfihlakalo: iziteshi zangaphakathi ezijikelezayo zivumela i-desulfurization slurry ukuthi ihlangane futhi ishayisane ngokuqhubekayo ekugelezeni, ekugcineni ibe amaconsi amancane nafanayo - lapho indawo yokuxhumana phakathi kwala maconsi negesi yomoya iba nkulu, kulapho ukusebenza kahle kokumuncwa kwe-sulfur dioxide kuba phezulu.
Okubaluleke kakhulu, ayivaleki kalula. Izinhlayiya ezincane ngokungenakugwenywa zixutshwe zibe yizibi zezimboni, futhi imigudu emincane yama-nozzle avamile ivaleka kalula, okuholela ekufuthweni okungalingani kanye nokunciphisa ukusebenza kahle kokukhipha i-sulfurization. Umklamo wesiteshi sokugeleza kwe-nozzle ye-silicon carbide ubanzi, uvumela izinhlayiya ukuba zidlule kahle, okunciphisa kakhulu isikhathi sokungasebenzi kanye nokugcinwa okubangelwa ukuvaleka.
3, 'Ukukhetha okubalulekile' ngaphansi kwezinqubomgomo zokuvikela imvelo
Njengoba kunezindinganiso zemvelo eziqinile, amabhizinisi anezidingo eziphakeme zemishini yokususa i-sulfur. Isibonelo, umkhawulo wokuhlushwa kwe-sulfur dioxide kugesi ophumayo okhishwa yizitshalo zamandla uqiniswe kakhulu. Lokhu kusho ukuthi uhlelo lokususa i-sulfur kumele lusebenze kahle futhi luzinze - futhi ukusebenza kwe-nozzle kuthinta ngqo umphumela wokugcina wokuhlanza.
Nakuba izindleko zokuqala zokuthenga ama-nozzle e-silicon carbide desulfurization ziphakeme kunezama-nozzle avamile, empeleni azonga kakhulu ngokuhamba kwesikhathi. Impilo yayo yesevisi iphindwe kaningana kuneyama-nozzle epulasitiki, okunganciphisa kakhulu imvamisa yokushintsha kanye nokulahlekelwa yisikhathi sokuphumula. Kumabhizinisi aphishekela ukukhiqizwa okusimeme, isici "sokutshalwa kwezimali kanye kuphela, okungenakukhathazeka isikhathi eside" sibaluleke kakhulu.
4, Akuyona nje i-desulfurization, izinhlelo zokusebenza zesikhathi esizayo ziyabonakala
Ngaphezu kokwelashwa kwegesi yoketshezi lwezimboni, amandla ezinto ze-silicon carbide ayavela emikhakheni eminingi. Ukumelana kwayo nokushisa okuphezulu kanye nokumelana nemisebe kwenza ivelele emikhakheni ephezulu njengamandla enuzi kanye nezindiza; Embonini yamandla amasha, isetshenziswa futhi emishinini yokushisa ephezulu yezinto zebhethri le-lithium. Njenge-nozzle yokususa i-sulfurization, isalokhu iyingxenye ebalulekile yokuphathwa kwemvelo kwamanje.
Le ngxenye encane 'efihliwe embhoshongweni wokususwa kwesibabule empeleni iyibhuloho phakathi kwempucuko yezimboni nokuvikelwa kwemvelo. Isebenzisa ukuhlakanipha kwesayensi yezinto ezibonakalayo ukuze yenze kube nokwenzeka ukuthi ukukhiqizwa kwezimboni kuhambisane nesibhakabhaka esiluhlaza okwesibhakabhaka namafu amhlophe - mhlawumbe incazelo engcono kakhulu yobuchwepheshe obuvikela imvelo.
