Ukugeleza kwenqubo ye-desulfurization mpo roller isigayouhlelo lubushelelezi, ukutshalwa kwezimali kugcinwa futhi nokuphathwa kokukhiqiza kulula.Lapho kukhethwa uhlelo lwenqubo yokukhiqiza kanye nokukhethwa kwemishini ye-desulfurization limestone powder, izinqubo ezintsha ezivuthiwe nezithembekile zizokwamukelwa, okongayo, okunengqondo, okusebenzayo futhi okuthembekile.I-HCMilling(Guilin Hongcheng), njengomklamo wohlelo kanye nomkhiqizi wesistimu yokugaya i-roller eqondile ye-desulfurization, izokwethula umphumela we-desulfurization we-vertical roller mill.
I-HLMdesulfurization mpo roller isigayo
Izinto ezimbalwa eziyinhloko ezithinta ukusebenza kahle kwe-desulfurization:
1. Ibanga le-Limestone
Ibanga le-Limestone linqunywa okuqukethwe kwe-CaO.Okuqukethwe okuphezulu kwe-CaO ye-limestone ehlanzekile ngu-56%.Ukuphakama kwe-limestone ukuhlanzeka, kungcono ukusebenza kahle kwe-desulfurization.Njengomklami wenqubo, lapho uklama izithako, akufanele nje ubale ukwakheka kwamakhemikhali ayo, kodwa futhi uqonde izici zayo ezibonakalayo.Okuqukethwe kwe-calcium oxide ye-limestone yebanga lokuqala yi-48% - 54%;I-Limestone ayidingi okuqukethwe kwe-CaO ephezulu.I-Limestone ene-CaO>54% inokuhlanzeka okuphezulu futhi i-marmated.Akulula ukugaya futhi kunokuqina kwamakhemikhali okuqinile, ngakho-ke akufanelekile ukusetshenziswa njenge-desulfurizer.
2. Ubuhle bempushana ye-limestone
Ubukhulu bezinhlayiyana zempushana ye-limestone buba nkulu, indawo ethile engaphezulu iyanda.Njengoba ukuncibilika kwe-limestone kuwuketshezi oluqinile lwezigaba ezimbili, futhi izinga layo lokusabela lilingana nendawo ethile yezinhlayiya ze-limestone, izinhlayiya ze-limestone ezicolekile zinokusebenza okuhle kokuncibilika, amazinga okusabela ahlukahlukene ahlobene aphezulu, ukusebenza kahle okuphezulu kwe-desulfurization kanye ukusetshenziswa kwe-limestone, kodwa uma usayizi wezinhlayiya ze-limestone uncane, uyanda ukusetshenziswa kwamandla okucindezelayo.Ngokuvamile, izinga lokudlula kwempushana ye-limestone edlula isisefo semeshi engama-325 (ama-microns angama-44) singama-95%.
Ngesikhathi esifanayo, ubukhulu bezinhlayiya ze-limestone powder buhlobene nekhwalithi ye-limestone.Ukuze kuqinisekiswe ukuthi ukusebenza kahle kwe-desulfurization kanye nezinga lokusebenzisa i-limestone lifinyelela izinga elithile, lapho okuqukethwe kokungcola kwe-limestone kuphezulu, i-limestone kufanele icoliswe kahle.
Ubuchwepheshe bokulungisa i-limestone powder usebenzisa desulfurization mpo roller isigayouhlelo:
Ngenqubo ye-FGD kusetshenziswa impushana ye-limestone njenge-desulfurizer, impushana ye-limestone idinga ukusabela koketshezi oluqinile lwezigaba ezimbili, futhi izinga lokusabela lihle endaweni ethile yezinhlayiya ze-limestone.Ubukhulu bezinhlayiyana zezinhlayiya zempushana ye-limestone buba nkulu, indawo ethile ngobuningi iba nkulu.Izinhlayiya ze-limestone zinokuncibilika okuhle, futhi amazinga okusabela ahlobene ahlukahlukene aphezulu.Kodwa-ke, lapho usayizi wezinhlayiyana ze-limestone uba mncane, uyanda ukusetshenziswa kwamandla okuchotshozwa.Ngokuvamile, izinga lokudlula kwempushana ye-limestone edlula isisefo semeshi engama-325 (ama-microns angama-44) singama-95%.Ngesikhathi esifanayo, ubukhulu bezinhlayiya ze-limestone powder buhlobene nekhwalithi ye-limestone.Ukuze kuqinisekiswe ukuthi ukusebenza kahle kwe-desulfurization kanye nezinga lokusebenzisa i-limestone lifinyelela izinga elithile, lapho okuqukethwe kokungcola kwe-limestone kuphezulu, i-limestone izocoliswa kancane kancane.Ubuchwepheshe bokugaya amashubhu bendabuko busetshenziselwa ukulungisa impushana ye-limestone, esebenzisa amandla amakhulu, okukhiphayo okuphansi, ukugeleza kwenqubo eyinkimbinkimbi, futhi okunzima ukulawula ukucoleka kanye nokugreda kwezinhlayiyana.Ngokuthuthukiswa kobuchwepheshe bokugaya, kwamukelwa ubuchwepheshe bokugaya i-roller mpo.Ngenxa yesimiso sokugaya ungqimba lwempahla, ukusetshenziswa kwamandla kuphansi (20-30% ngaphansi kokusetshenziswa kwamandla kwesigayo se-tube), ukwakheka kwamakhemikhali omkhiqizo kuzinzile, ukuhlukaniswa kwezinhlayiyana kufana, futhi ukugeleza kwenqubo kulula. .
I-limestone engena esitshalweni ikhishwa ku-hopper ngeloli noma i-forklift, futhi i-limestone igaywe esigabeni esisodwa.Amabhulokhi e-limestone athunyelwa ku-crusher ngesiphakeli sepuleti.Usayizi wezinhlayiyana zokudla ngokuvamile ulawulwa ku-400-500mm, futhi usayizi wezinhlayiyana ezikhiphayo ulawulwa cishe ku-15mm.I-limestone echotshoziwe ithunyelwa esiseleni se-limestone ngempahla yokuthutha, futhi indawo engaphezulu yesisele ifakwe umqoqi owodwa wokukhipha uthuli.I-limestone echotshoziwe ilinganiswa futhi ihlanganiswe nesisindo sebhande elilawula isivinini esingaphansi kwesisele, bese ifakwa emshinini wokugaya ome mpo ngomthumeli webhande ukuze igaywe.Umkhiqizo oqediwe uyimpushana ye-limestone enobunono obungamameshe angama-250.Impushana ye-limestone ngemva kokugaya ithuthelwa endaweni yokugcina impahla eqediwe ukuze igcinwe.Phezulu kwendawo yokugcina impahla ifakwe umqoqi owodwa wothuli wokukhipha uthuli.Imikhiqizo eqediwe ilethwa elolini lethangi lenqwaba ukuze ilethwe ngomshini wenqwaba ezansi kwendawo yokugcina impahla.
Umphumela we-Desulfurization wempo roller mill:
Inqubo yokugaya yeI-HLMmpo roller mill yamukela isimiso sokugaya ungqimba wezinto ezibonakalayo, ngokucindezela kokugaya okulungisekayo, umsindo ophansi, ukusetshenziswa kwamandla aphansi, ukuguga okuphansi, ukuguquguquka okuqinile ezintweni, ukugeleza kwenqubo elula nokusebenza kahle kwesistimu ephezulu.Lonke uhlelo lusebenza ngaphansi kwengcindezi engemihle ngokungcola okuncane kothuli.Inqubo yokugaya yesigayo se-roller mpo inokulinganisa okusanhlamvu okufanayo, ukucoleka komkhiqizo okulungisekayo (ukulunga komkhiqizo kufinyelela kumameshi angama-600 noma ngaphezulu), futhi ukucoleka komkhiqizo kungakalwa ngokushesha futhi kulungiswe.
Uma unezidingo ezihlobene, sicela usithinte ukuze uthole imininingwane yesisetshenziswa futhi usinikeze imininingwane elandelayo:
