Ukuhlanzwa kwe-flue gas ngokumiswa kwe-lime
Ukuze i-desulphurisation emanzi ye-flue gas, idluliswa nge-absorber (scrubber). Ukumiswa kwe-lime okunikezwa ku-absorber (i-limestone noma ubisi lwe-lime) kuhlangana ne-sulphur dioxide ephuma ku-flue gas. Uma kungcono ukudluliswa kwenqwaba, i-desulphurisation iphumelela kakhulu.
Ngesikhathi esifanayo nokumuncwa, igesi ye-flue igcwala umhwamuko wamanzi. Okubizwa ngokuthi "igesi ehlanzekile" ngokuvamile ikhishwa ngoshimula omanzi noma umbhoshongo wokupholisa. Amanzi alahlekile ngaleyo ndlela kumele ashintshwe. I-lime slurry empontshelwa ekujikelezeni igcinwa isebenza ngamakhemikhali ngokukhipha ngokuphindaphindiwe ukugeleza okugcwele okugcwele futhi esikhundleni sako kufakwe ukumiswa okusha okusebenzayo. Ukugeleza kwengxenye ekhishiwe kuqukethe i-gypsum, - eyenziwe lula - iwumkhiqizo wokusabela we-lime nesibabule futhi ingathengiswa ngemva kokukhipha amanzi (isib. izindonga ze-gypsum embonini yokwakha).
Ama-nozzles e-ceramic akhethekile asetshenziselwa ukujova ukumiswa kwe-lime ku-absorber. Lawa mabhomu enza amaconsi amaningi amancane asuka ekumisweni okumponthiwe futhi ngaleyo ndlela abe indawo yokusabela enkulu ngokuhambisanayo ukuze kudluliswe isisindo esihle. Izinto ze-ceramic zivumela impilo ende yesevisi naphezu kweqiniso lokuthi ukumiswa kwe-lime nokuqukethwe kwe-gypsum kunezinto ezilimazayo. Kumklamo sinamathisela ukubaluleka okukhulu ezigabeni eziphambanayo zamahhala, ukuze ukungcola okuncane ekumisweni kungakwazi ukusetha imibhobho. Ukuze usebenze ngendlela eyongayo, lawa ma-nozzle angashintshwa abe yibanga eliphakeme kakhulu lephampu. Umbhobho ungacaciswa (cishe) yonke inselele yobunjiniyela benqubo. Ukwengeza imibhobho yekhoni egcwele kanye ne-hollow-cone kuma-engeli ahlukene wokufutha kanye namazinga okugeleza, umlomo wombhobho we-ZPC onesinxephezelo se-twist esinelungelo lobunikazi nawo uyatholakala.
Indawo yokumunca iqukethe amaleveli amaningana emibhobho kanye nesistimu yokuhlukanisa amaconsi efakwe ngokuvundlile, ukuze kubuyiselwe amaconsi amahle athwalwa emfudlaneni wegesi kunqubo. Ngezihlukanisi zethu ezisezingeni eliphezulu ze-droplet ungakwazi ukwandisa ukusebenza kahle kwesitshalo sakho.
Okuqinile ekumisweni kungaholela ekufakweni kwemali, isb kusihlukanisi samaconsi, epayipini lokungena noma kumapayipi, okungaholela ezinkingeni ekusebenzeni. Njengoba amanzi ehlala ehoxiswa kumjikelezo ngokusebenzisa ukuhwamuka, amanzi kufanele afakwe ku-absorber, engasetshenziselwa futhi kufanele isetshenziselwe ukuhlanza. Imibhobho yolimi ye-ZPC isizibonakalise ukuthi iyahlanza i-flue gas inlet. Imibhobho ye-ZPC egcwele i-cone ngokuvamile isetshenziselwa ukuhlanza izihlukanisi zamaconsi.
Amapulastiki (isb. amapayipi) kanye nerabha (isb. ama-gaskets, amalayini enjoloba, njll.) avame ukusetshenziswa kusixhumi esimelana nezinga lokushisa eliphansi kunezinga lokushisa legesi ephuma umoya epholile. Ngokuvamile, ukumiswa okupompelwa kusekethe kupholisa igesi ye-flue ngokwanele, kodwa uma, isibonelo, iphampu yokuphakelayo imisiwe, amapulasitiki namarabha angabhujiswa. Imibhobho yensimbi eyisipesheli eyisipesheli ifakazele ukubaluleka kwayo lapha, ethatha indawo yokupholisa ngalesi sikhathi futhi ngaleyo ndlela ivikele ukutshalwa kwezimali kwesikhungo se-flue gas desulphurisation.
I-Reaction bonded silicon carbide (SiSiC): Ubulukhuni be-Moh bungu-9.2, bukwazi ukumelana kahle nokuguguleka nokugqwala, ukumelana okuhle kakhulu nokuhuzuka kanye ne-anti-oxidation. Inamandla izikhathi ezi-4 kuya kwezi-5 kune-nitride eboshiwe i-silicon carbide. Impilo yesevisi yinde izikhathi eziyisi-7 kuye kweziyi-10 kunempahla ye-alumina. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi.
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.
