Ukuhamba kwenkquboi-desulfurization ethe nkqo roller millInkqubo igudileyo, utyalo-mali luyagcinwa kwaye ulawulo lwemveliso lulula. Xa ukhetha isicwangciso senkqubo yemveliso kunye nokukhethwa kwezixhobo ze-desulfurization limestone powder, kuya kusetyenziswa iinkqubo ezintsha kunye netekhnoloji ezivuthiweyo nezithembekileyo, ezingabizi kakhulu, ezifanelekileyo, ezisebenzayo nezithembekileyo. I-HCMilling (Guilin Hongcheng), njengoyilo lweskimu kunye nomenzi wenkqubo ye-desulfurization vertical roller mill, iya kwazisa isiphumo se-desulfurization se-vertical roller mill.

I-HLMi-desulfurization ethe nkqo roller mill

Izinto eziphambili ezininzi ezichaphazela ukusebenza kakuhle kwe-desulfurization:

1. Udidi lweLimestone

Udidi lweLimestone lumiselwa ngumxholo weCaO. Umxholo ophezulu weCaO kwilimestone ecocekileyo yi-56%. Okukhona ubumsulwa belimestone buphezulu, kokukhona ukusebenza kakuhle kwe-desulfurization. Njengomyili wenkqubo, xa uyila izithako, akufuneki ubale kuphela ukwakheka kwayo kweekhemikhali, kodwa nokuqonda iimpawu zayo zomzimba. Umxholo wecalcium oxide kwilimestone yodidi lokuqala yi-48% - 54%; Ilimestone ayifuni mfuneko yokuba ibe nomxholo ophezulu weCaO. Ilimestone eneCaO>54% icocekile kakhulu kwaye i-marmatized. Akulula ukuyigaya kwaye izinzile kakhulu kwiikhemikhali, ngoko ke ayifanelekanga ukusetyenziswa njenge-desulfurizer.

2. Ubunzima bomgubo welitye lekalika

Okukhona ubukhulu besuntswana lomgubo welimestone buncinci, kokukhona indawo ethile yomphezulu inkulu. Njengoko impendulo yokunyibilika kwelimestone iyimpendulo yesigaba esiqinileyo-solid-phase-two, kwaye izinga layo lokusabela lihambelana nendawo ethile yomphezulu wesuntswana welimestone, amasuntswana elimestone acolekileyo asebenza kakuhle ekunyibilikeni, amazinga aphezulu okusabela ahambelanayo, ukusebenza kakuhle kwe-desulfurization kunye nokusetyenziswa kwesuntswana lelimestone, kodwa okukhona ubukhulu besuntswana lelimestone buncinci, kokukhona ukusetyenziswa kwamandla okutyumza kuphezulu. Ngokubanzi, izinga lokudlula komgubo welimestone odlula isihluzo se-325 mesh (44 microns) yi-95%.

Kwangaxeshanye, ubungakanani bamasuntswana e-limestone powder bunxulumene nomgangatho we-limestone. Ukuze kuqinisekiswe ukuba ukusebenza kakuhle kwe-desulfurization kunye nesantya sokusetyenziswa kwe-limestone sifikelela kwinqanaba elithile, xa umxholo wokungcola kwi-limestone uphezulu, i-limestone kufuneka icolwe kakuhle.

Iteknoloji yokulungiselela umgubo welimestone kusetyenziswa i-desulfurization ethe nkqo roller millinkqubo:

Kwinkqubo ye-FGD esebenzisa umgubo welimestone njenge-desulfurizer, umgubo welimestone kufuneka ungene kwi-solid liquid dissolving reaction yezigaba ezimbini, kwaye izinga lokusabela lilungile kwindawo ethile yomphezulu wee-limestone particles. Okukhona ubukhulu bee-particles ze-limestone powder buncinci, kokukhona indawo ethile yomphezulu ikhulu ngobunzima. Ii-limestone particles zinyibilika kakuhle, kwaye amazinga okusabela ahlukeneyo ahambelanayo aphezulu. Nangona kunjalo, ubukhulu bee-particles ze-limestone buncinci, kokukhona ukusetyenziswa kwamandla aphezulu kokutyumza. Ngokubanzi, izinga lokudlula komgubo welimestone odlula kwi-325 mesh sieve (44 microns) yi-95%. Kwangaxeshanye, ubungakanani bee-particles ze-limestone powder buhambelana nomgangatho we-limestone. Ukuqinisekisa ukuba ukusebenza kakuhle kwe-desulfurization kunye nezinga lokusetyenziswa kwe-limestone kufikelela kwinqanaba elithile, xa umxholo wokungcola kwi-limestone uphezulu, i-limestone kufuneka icolwe ngakumbi. Itekhnoloji yendabuko ye-tube mill isetyenziselwa ukulungiselela umgubo welimestone, osetyenziswa kakhulu, imveliso ephantsi, ukuhamba kweenkqubo ezinzima, kwaye kunzima ukulawula ubuncinci kunye nokuhlelwa kwee-particles. Ngophuhliso lwetekhnoloji yokugaya, kusetyenziswa itekhnoloji yokugaya i-vertical roller mill. Ngenxa yomgaqo wokusila umaleko wezinto, ukusetyenziswa kwamandla kuphantsi (ngama-20-30% ngaphantsi kokusetyenziswa kwamandla kwi-tube mill), ukwakheka kweekhemikhali kwimveliso kuzinzile, ukuhlelwa kwamasuntswana kuyafana, kwaye ukuhamba kwenkqubo kulula.

Ilitye lekalika elingena kwisityalo likhutshwa kwi-hopper ngelori okanye ngefolokhwe, kwaye ilitye lekalika licoliwe kwinqanaba elinye. Iibhloko zelitye lekalika zithunyelwa kwi-crusher nge-plate feeder. Ubungakanani bezinto zokutya bulawulwa ngokubanzi kwi-400-500mm, kwaye ubungakanani bezinto ezikhuphayo bulawulwa malunga ne-15mm. Ilitye lekalika elicoliweyo lithunyelwa kwi-limestone silo ngezixhobo zokuhambisa, kwaye umphezulu wesilo uxhotyiswe ngesixhobo esinye sokuqokelela uthuli sokususa uthuli. Ilitye lekalika elicoliweyo lilinganiswa kwaye lixutywe yi-speed regulating belt weiger ezantsi kwesilo, kwaye emva koko lifakwe kwi-vertical roller mill yi-belt conveyor ukuze lisilwe. Imveliso egqityiweyo yi-limestone powder enobuncinci be-250 meshes. I-limestone powder emva kokusilwa ithuthwa iye kwindawo yokugcina imveliso egqityiweyo ukuze igcinwe. Umphezulu wendawo yokugcina impahla uxhotyiswe ngesixhobo esinye sokuqokelela uthuli sokususa uthuli. Iimveliso ezigqityiweyo zithunyelwa kwilori yetanki enkulu ukuze zihanjiswe ngumatshini we-bulk ezantsi kwendawo yokugcina impahla.

Isiphumo sokususa i-sulfurizationi-roller mill ethe nkqo:

Inkqubo yokugayaI-HLMi-roller mill ethe nkqo yamkela umgaqo wokusila womaleko wezinto, ngoxinzelelo lokusila oluhlengahlengiswayo, ingxolo ephantsi, ukusetyenziswa kwamandla aphantsi, ukuguguleka okuphantsi, ukuzivumelanisa nezimo kakhulu nezixhobo, ukuhamba kweenkqubo okulula kunye nokusebenza kakuhle kwenkqubo. Yonke inkqubo isebenza phantsi koxinzelelo olubi kunye nongcoliseko oluncinci lothuli. Inkqubo yokusila ye-vertical roller mill inomgangatho ofanayo weenkozo, ulungelelwaniso lwemveliso (ulungelelwaniso lwemveliso lunokufikelela kwi-600 meshes nangaphezulu), kwaye ulungelelwaniso lwemveliso lunokulinganiswa ngokukhawuleza kwaye lulungiswe.
