Inkqubo yokuhamba kwedesulfurization nkqo roller yokusilainkqubo igudileyo, utyalo-mali lugcinwe kwaye ulawulo lwemveliso lulula.Xa ukhetha isicwangciso senkqubo yokuvelisa kunye nokukhethwa kwezixhobo ze-desulfurization limestone powder, iinkqubo ezintsha ezivuthiweyo nezithembekileyo kunye nobuchwepheshe ziya kwamkelwa, ezinoqoqosho, ezinengqiqo, ezisebenzayo nezithembekileyo.I-HCMilling(Guilin Hongcheng), njengoyilo lwesikimu kunye nomvelisi wenkqubo yokusila ethe nkqo ye-desulfurization, iya kwazisa isiphumo se-desulfurization ye-roller yokusila ethe nkqo.

HLMdesulfurization nkqo roller yokusila

Izinto ezininzi eziphambili ezichaphazela ukusebenza kwe-desulfurization:

1. Ibakala likakalika

Umgangatho weLimestone umiselwa ngumxholo weCaO.Owona mxholo weCaO uphezulu welimestone esulungekileyo ngama-56%.Okukhona iphezulu ukucoceka limestone, ngcono desulfurization ukusebenza kakuhle.Njengomyili wenkqubo, xa uyila izithako, akufanele ubale kuphela ukubunjwa kweekhemikhali, kodwa uqonde iimpawu zayo ezibonakalayo.Umxholo we-calcium oxide we-limestone yebakala lokuqala yi-48% - 54%;I-Limestone ayifuni mxholo weCaO ephezulu.I-Limestone ene-CaO> 54% inobunyulu obuphezulu kwaye i-marmatised.Akulula ukugaya kwaye kunozinzo oluqinileyo lweekhemikhali, ngoko ke akufanelekanga ukusetyenziswa njenge-desulfurizer.

2. Ukulunga komgubo welimestone

Incinci isayizi yesuntswana le-limestone powder, inkulu indawo ethile.Njengoko ukunyibilika kwe-limestone kukusabela kwesigaba esomeleleyo solwelo, kwaye isantya sokusabela kwayo silingana nomhlaba othile wamasuntswana ekalika, amasuntswana ekalika acokisekileyo anokusebenza kakuhle kokunyibilika, amanqanaba aphezulu ahlukeneyo okusabela anxulumeneyo, ukusebenza okuphezulu kwe-desulfurization kunye Ukusetyenziswa kwe-limestone, kodwa incinci isayizi ye-limestone ye-limestone, iphezulu ukusetyenziswa kwamandla okutyumzayo.Ngokuqhelekileyo, izinga lokupasa kwe-limestone powder edlula i-325 mesh sieve (44 microns) yi-95%.

Ngelo xesha, ubungakanani be-particle ye-limestone powder ihambelana nomgangatho we-limestone.Ukuze kuqinisekiswe ukuba ukusebenza kakuhle kwe-desulfurization kunye nesantya sokusetyenziswa kwe-limestone kufikelela kwinqanaba elithile, xa umxholo wokungcola kwi-limestone uphezulu, i-limestone kufuneka icocwe.

Itekhnoloji yokulungiselela umgubo weLimestone usebenzisa desulfurization nkqo roller yokusilainkqubo:

Kwinkqubo ye-FGD kusetyenziswa umgubo welimestone njenge-desulfurizer, umgubo welimestone kufuneka utyhutyhe ulwelo oluluqilima olunezigaba ezibini, kwaye izinga lokusabela lilungile kumphezulu othile wamasuntswana ekalika.Ubungakanani besuntswana lomgubo wamasuntswana omgubo welimestone, kokukhona umkhulu indawo ethile ngokobunzima.Amasuntswana e-limestone anokunyibilika okuhle, kunye nemigangatho eyahlukeneyo yokusabela ehambelanayo aphezulu.Nangona kunjalo, incinci isayizi ye-limestone, iphezulu ukusetyenziswa kwamandla okutyumza.Ngokuqhelekileyo, izinga lokupasa kwe-limestone powder edlula i-325 mesh sieve (44 microns) yi-95%.Ngelo xesha, ubungakanani be-particle ye-limestone powder ihambelana nomgangatho we-limestone.Ukuqinisekisa ukuba i-desulfurization esebenzayo kunye nesantya sokusetyenziswa kwe-limestone ifikelela kwinqanaba elithile, xa umxholo wokungcola kwi-limestone uphezulu, i-limestone iya kucolwa ngakumbi.Itekhnoloji yemveli yokusila ityhubhu isetyenziselwa ukulungisa umgubo welimestone, osetyenziswa ngamandla amakhulu, ukukhutshwa okuphantsi, ukuhamba kwenkqubo entsonkothileyo, kwaye kunzima ukulawula ukucoleka kunye nokuhlelwa kwamasuntswana.Ngophuhliso lwetekhnoloji yokugaya, itekhnoloji yokugaya i-roller ethe nkqo yamkelwa.Ngenxa yomgaqo-siseko wokugaya, ukusetyenziswa kwamandla kuphantsi (20-30% ngaphantsi kokusetyenziswa kwamandla e-tube mill), ukwakheka kweekhemikhali zemveliso kuzinzile, i-particle gradation ifana, kwaye inkqubo yokuhamba ilula. .

I-limestone engena kwisityalo ikhutshwe kwi-hopper ngelori okanye i-forklift, kwaye i-limestone ichithwa kwinqanaba elinye.Iibhloko ze-limestone zithunyelwa kwi-crusher ngokusebenzisa i-plate feeder.Ubungakanani beqhekeza lokutya ngokuqhelekileyo bulawulwa kwi-400-500mm, kwaye ubungakanani beengqungquthela zokukhupha zilawulwa malunga ne-15mm.I-limestone etyumkileyo ithunyelwa kwisisele se-limestone ngesixhobo sokuhambisa, kwaye umphezulu wesisele uxhotyiswe ngomqokeleli wothuli omnye wokususwa kothuli.I-limestone etyunyuziweyo ibalwa kwaye ihlanganiswe ngesantya esilawula ibhanti esezantsi kwe-silo, kwaye ifakwe kwi-roller yokusila ethe nkqo yi-conveyor yebhanti yokusila.Imveliso egqityiweyo i-limestone powder kunye ne-fineness ye-250 meshes.Ipowder ye-limestone emva kokugaya ithunyelwa kwindawo yokugcina imveliso egqityiweyo yokugcina.Umphezulu wendawo yokugcina impahla uxhotyiswe ngomqokeleli wothuli omnye wokususa uthuli.Iimveliso ezigqityiweyo zihanjiswa kwilori yetanki yesambuku ukuze zihanjiswe ngomatshini omninzi ezantsi kwendawo yokugcina impahla.

Isiphumo se-Desulfurization yeilitye lokusila elithe nkqo:

Inkqubo yokusila yeHLMilitye lokusila elithe nkqo ithatha umgaqo wokusila wezinto eziphathekayo, kunye noxinzelelo oluguquguqukayo lokusila, ingxolo ephantsi, ukusetyenziswa kwamandla aphantsi, ukunxiba okuphantsi, ukuguquguquka okunamandla kwizinto eziphathekayo, ukuhamba kwenkqubo elula kunye nokusebenza kakuhle kwenkqubo.Inkqubo yonke iqhutywa phantsi koxinzelelo olubi kunye nongcoliseko lothuli oluncinci.Inkqubo yokusila ye-vertical roller mill inokulinganisa okuziinkozo okufanayo, ukulungiswa kwemveliso eguquguqukayo (ubuhle bemveliso bunokufikelela kwii-meshes ezingama-600 okanye ngaphezulu), kwaye ukucolwa kwemveliso kunokulinganiswa ngokukhawuleza kwaye kulungiswe.
