Ukugeleza kwenqubo yeisigayo se-roller esiqondile se-desulfurizationuhlelo lubushelelezi, ukutshalwa kwezimali kuyalondolozwa futhi ukuphathwa kokukhiqiza kulula. Lapho ukhetha uhlelo lwenqubo yokukhiqiza kanye nokukhethwa kwemishini yempuphu ye-limestone yoku-desulfurization, izinqubo ezintsha ezivuthiwe nezithembekile kanye nobuchwepheshe kuzosetshenziswa, ezingabizi, ezinengqondo, ezisebenzayo nezithembekile. I-HCMilling (Guilin Hongcheng), njengomklamo wohlelo kanye nomkhiqizi wohlelo lwe-desulfurization vertical roller mill, izokwethula umphumela we-desulfurization we-vertical roller mill.

I-HLMisigayo se-roller esiqondile se-desulfurization

Izici eziningana eziyinhloko ezithinta ukusebenza kahle kwe-desulfurization:

1. Ibanga le-limestone

Izinga le-limestone linqunywa okuqukethwe yi-CaO. Okuqukethwe kwe-CaO okuphezulu kakhulu kwe-limestone emsulwa kungu-56%. Uma ubumsulwa be-limestone buphakeme, kungcono ukusebenza kahle kwe-desulfurization. Njengomklami wenqubo, lapho uklama izithako, akufanele nje ubale ukwakheka kwamakhemikhali ayo, kodwa futhi uqonde izakhiwo zayo zomzimba. Okuqukethwe kwe-calcium oxide kwe-limestone yebanga lokuqala kungu-48% - 54%; I-limestone ayidingi ngempela okuqukethwe kwe-CaO okuphezulu. I-limestone ene-CaO>54% ihlanzekile kakhulu futhi i-marmatized. Akulula ukuyigaya futhi inamandla aqinile okuzinza kwamakhemikhali, ngakho-ke ayifanele ukusetshenziswa njenge-desulfurizer.

2. Ubuncane bempuphu ye-limestone

Uma usayizi wezinhlayiya zempuphu ye-limestone uncane, kulapho indawo ethile yobuso inkulu khona. Njengoba ukusabela kokuncibilika kwe-limestone kuyimpendulo eqinile-ewuketshezi enezigaba ezimbili, futhi izinga lokusabela kwayo lilingana nendawo ethile yobuso bezinhlayiya ze-limestone, izinhlayiya ze-limestone ezicolekile zisebenza kahle ekuncibilikeni, amazinga aphezulu okusabela ahlobene, ukusebenza kahle okuphezulu kokukhipha i-sulfurization kanye nokusetshenziswa kwe-limestone, kodwa uma usayizi wezinhlayiya ze-limestone uncane, kulapho ukusetshenziswa kwamandla okuchotshozwa kukhuphuka khona. Ngokuvamile, izinga lokudlula kwempuphu ye-limestone edlula isihlungi se-mesh esingu-325 (44 microns) lingu-95%.

Ngesikhathi esifanayo, ubukhulu bezinhlayiya zempuphu ye-limestone buhlobene nekhwalithi ye-limestone. Ukuze kuqinisekiswe ukuthi ukusebenza kahle kwe-desulfurization kanye nezinga lokusetshenziswa kwe-limestone kufinyelela ezingeni elithile, lapho okuqukethwe kokungcola ku-limestone kuphezulu, i-limestone kufanele igaywe kahle.

Ubuchwepheshe bokulungiselela i-lime powder kusetshenziswa isigayo se-roller esiqondile se-desulfurizationuhlelo:

Ngenqubo ye-FGD esebenzisa i-limestone powder njenge-desulfurizer, i-limestone powder idinga ukusabela okuqinile kokuncibilika kwezigaba ezimbili, futhi izinga lokusabela lihle endaweni ethile yobuso bezinhlayiya ze-limestone. Uma ubukhulu bezinhlayiya ze-limestone powder buncane, indawo ethile yobuso ikhulu ngobuningi. Izinhlayiya ze-limestone zinokuncibilika okuhle, futhi amazinga ahlukahlukene okusabela ahlobene aphezulu. Kodwa-ke, uma ubukhulu bezinhlayiya ze-limestone buncane, ukusetshenziswa kwamandla okuphezulu kokuchotshozwa. Ngokuvamile, izinga lokudlula kwe-limestone powder edlula isihlungi se-mesh esingu-325 (44 microns) lingu-95%. Ngesikhathi esifanayo, ubukhulu bezinhlayiya ze-limestone powder buhlobene nekhwalithi ye-limestone. Ukuze kuqinisekiswe ukuthi ukusebenza kahle kwe-desulfurization kanye nezinga lokusetshenziswa kwe-limestone kufinyelela ezingeni elithile, lapho okuqukethwe kokungcola ku-limestone kuphezulu, i-limestone kufanele icwebe kakhulu. Ubuchwepheshe bendabuko bokugaya amashubhu busetshenziselwa ukulungiselela i-limestone powder, esetshenziswa kakhulu, ekhipha amandla amancane, i-process flow eyinkimbinkimbi, futhi kunzima ukulawula ubuncane kanye nokuhlelwa kwezinhlayiya. Ngokuthuthuka kobuchwepheshe bokugaya, kusetshenziswa ubuchwepheshe bokugaya be-roller mill obuqondile. Ngenxa yesimiso sokugaya ungqimba lwezinto ezibonakalayo, ukusetshenziswa kwamandla kuphansi (kungaphansi ngo-20-30% kunokusetshenziswa kwamandla kwe-tube mill), ukwakheka kwamakhemikhali komkhiqizo kuzinzile, ukwakheka kwezinhlayiya kuyafana, futhi ukugeleza kwenqubo kulula.

I-limestone engena esitshalweni ikhishwa iyiswe kwi-hopper ngeloli noma i-forklift, bese i-limestone ichotshozwa ngesigaba esisodwa. Amabhulokhi e-limestone athunyelwa ku-crusher nge-plate feeder. Usayizi wezinhlayiya zokudla ngokuvamile ulawulwa ku-400-500mm, kanti usayizi wezinhlayiya ezikhiphayo ulawulwa cishe ku-15mm. I-limestone echotshoziwe ithunyelwa kwi-limestone silo ngemishini yokuthutha, kanti phezulu kwe-silo kufakwe umqoqi wothuli olulodwa lokususa uthuli. I-limestone echotshoziwe ilinganiswa futhi ihlanganiswe nge-speed regulation belt weigher phansi kwe-silo, bese ifakwa ku-vertical roller mill yi-belt conveyor ukuze igaywe. Umkhiqizo oqediwe uyi-limestone powder enobukhulu obungama-meshes angu-250. I-limestone powder ngemva kokugaya ithuthwa iye e-finished product warehouse ukuze igcinwe. Ingxenye ephezulu ye-warehouse ifakwe umqoqi wothuli olulodwa lokususa uthuli. Imikhiqizo eqediwe ilethwa elolini le-bulk tank ukuze ithunyelwe ngomshini we-bulk phansi kwe-warehouse.

Umphumela wokususa i-sulfurizationumshini wokugaya oqondile:

Inqubo yokugayaI-HLMumshini wokugaya oqondile yamukela isimiso sokugaya ungqimba lwezinto ezibonakalayo, ngokucindezela kokugaya okulungisekayo, umsindo ophansi, ukusetshenziswa kwamandla aphansi, ukuguguleka okuphansi, ukuzivumelanisa nezimo kakhulu nezinto zokwakha, ukugeleza kwenqubo okulula kanye nokusebenza kahle kwesistimu ephezulu. Lonke uhlelo lusebenza ngaphansi kwengcindezi engemihle enokungcola okuncane kothuli. Inqubo yokugaya ye-vertical roller mill inokulinganisa okusanhlamvu okufanayo, ukucwebezela komkhiqizo okulungisekayo (ukucwebezela komkhiqizo kungafinyelela kuma-meshes angu-600 noma ngaphezulu), futhi ukucwebezela komkhiqizo kungalinganiswa ngokushesha futhi kulungiswe.

Uma unezidingo ezihlobene, sicela usithinte ukuze uthole imininingwane ngemishini bese usinike ulwazi olulandelayo:
