Indawo yokusila yamalahle yinxalenye ebalulekileyo yenkqubo yokucola kunye nesixhobo esibalulekileyo esincedisayo kwiplanti yombane.Umsebenzi walo oyintloko kukuphula kunye nokugaya amalahle kumalahle atyunyuziweyo ukubonelela ngezixhobo zebhoyili, ukucwangciswa kwayo kuya kuchaphazela ngokuthe ngqo ukhuseleko kunye noqoqosho lweyunithi.Ngenxa yokuba ukulungelelaniswa kwezixhobo zamalahle ezahlukeneyo kwiintlobo ezahlukeneyo zamalahle kwahluke kakhulu, kudityaniswa nemeko yokwenyani yokusasazwa ngokungalinganiyo kweemveliso zamalahle e-China, umgangatho weemveliso zamalahle uya kuchaphazela ngokuthe ngqo uqoqosho lwenkqubo yokucola.Ke, kufuneka kukhethwe njani izixhobo zokusila amalahle?HCM oomatshininjengomvelisi welitye lokusila, uya kwazisa isiseko sokhetho lwesisila samalahle.Kukho iintlobo ezininzi zelitye lokusila, ngokwesantya samacandelo asebenzayo okusila kuluhlu lokukhetha izixhobo zokusila zingahlulwa zibe ziindidi ezintathu, ezizezi: ilitye lokusila eliphantsi kwesantya esiphantsi, i-medium-speed coal mill kunye ne-high-speed coal mill. .Oku kulandelayo kuya kwazisa ukukhethwa kwezi zixhobo zintathu zokusila amalahle ngokulandelelanayo.
Ukukhetha izixhobo zokusila amalahle 1: isisila samalahle esinesantya esiphantsi
Ummeli oqhelekileyo wesantya esisezantsi sokugaya amalahle yibhola lebhola.Umgaqo osebenzayo ngulo: i-motor enamandla kakhulu ngebhokisi yegiya ukuqhuba oku kujikeleziswa kwepleyiti engqukuva, ibhola yentsimbi kwindlela elula ijikeleziswa ukuya kumphakamo othile ize iwe phantsi, ngenxa yempembelelo yebhola yentsimbi kumalahle naphakathi. ibhola yensimbi, phakathi kwebhola yentsimbi kunye nepleyiti yokulinda, amalahle aphantsi.Ilahle elirhabaxa elingenasiphako liyahlulwa xa liqukuqela kwisahluli somgubo orhabaxa ngasemva kwelitye lokusila, lize lithunyelwe kwipleyiti ejikelezayo ukusuka kwityhubhu yomgubo wokubuya ukuze ugaye kwakhona.Ukongeza ekuthuthweni komgubo wamalahle, umoya oshushu nawo udlala indima yokomisa amalahle.Ngoko ke, umoya oshushu ubizwa ngokuba yi-desiccant kwi-powder system.Imveliso ineempawu zexesha elide eliqhubekayo lokusebenza, ukugcinwa lula, ukuveliswa okuzinzile kunye nokulunga, umthamo omkhulu wokugcina, ukuphendula ngokukhawuleza, ukuguquguquka okukhulu kokusebenza, umlinganiselo ophantsi wamalahle, ukugcinwa komatshini wamalahle, uluhlu olubanzi lokusila amalahle njalo njalo.Ikakhulu isetyenziselwa amalahle aqinileyo naphakathi, ngakumbi amalahle anomthamo oguquguqukayo ophezulu kunye nepropathi eyomeleleyo yokurhawuka.Nangona kunjalo, eli litye lokusila lebhola elinesantya esiphantsi lininzi, lisebenzisa isinyithi esikhulu, lithatha umhlaba omninzi, kwaye linotyalo-mali oluphezulu.Ngoko ke ilitye lokusila lilungele ukusebenza komthwalo opheleleyo.
Isixhobo sokusila samalahle uhlobo 2:isantya esiphakathi sokusila amalahle
Indawo yokusila yamalahle esantya esiphakathi ikwabizwa ngokuba sisisila sokusila esithe nkqo, esiphawulwa ngamalungu okusila ahlanganiswe ngamaqela amabini entshukumo enxulumene nomzimba wokusila.Amalahle ayacudiswa aze acolwe phakathi kweendawo ezimbini zokusila aze atyunyuzwe.Kwangaxeshanye, umoya oshushu ngomsila womisa amalahle kwaye uthumela amalahle acoliweyo kwisahlukanisi kwindawo engasentla yendawo yokusila.Emva kokwahlula, amalahle ahlanjululweyo obungakanani obuthile athathwe kwi-mill kunye nokuhamba komoya, kwaye amalahle acolile aphindiweyo abuyiselwa kwindawo yokugaya ukuze aphinde agaywe.Isixhobo sokusila samalahle esinesantya esiphakathi sineengenelo zezixhobo ezixineneyo, unyawo oluncinci, ukonga ukusetyenziswa kwamandla (malunga ne-50% ~ 75% yelitye lokusila), ingxolo ephantsi, ukukhanya kunye nolawulo lokusebenza olubuthathaka.Kodwa ayifanelanga ukucola amalahle aqina ngakumbi.
Ukukhetha izixhobo zokusila amalahle 3: ilitye lokusila elinesantya esiphezulu
Isantya se-high-speed coal mill yi-500 ~ 1500 r/min, eyona nto ihlanganiswe ne-rotor ephezulu kunye negobolondo lokugaya.Ukusila kwefeni eqhelekileyo kunye nesando sokugaya njalo njalo.Kwilitye lokusila, amalahle atyunyuzwa kukungqubana phakathi kwempembelelo yesantya esiphezulu kunye negobolondo lokusila kunye nokungqubana kwamalahle.Olu hlobo lwelitye lokusila kunye ne-pulverized coal separator luphela, isakhiwo silula, sihlangene, utyalo-mali lokuqala luphantsi, lufanelekile ngokukhethekileyo ukugaya i-lignite ephezulu yokufuma kunye nomxholo oguquguqukayo ophezulu, kulula ukugaya amalahle e-bituminous.Nangona kunjalo, ngenxa yokuba ipleyiti yempembelelo ikhukuliswe ngokuthe ngqo kwaye inxitywe ukuhamba komoya, ubomi bayo benkonzo ngokuqhelekileyo bumalunga ne-1000h kuphela xa ukugaya i-lignite, ukutshintshwa rhoqo, kwaye umxholo wamanzi wamalahle omhlaba akufanele ube phezulu kakhulu, osetyenziswa ngokubanzi iibhoyila ezivuthelwe ngokuthe ngqo kwizixhobo zombane, kwaye akufanelekanga ukuba zisetyenziselwe iindibano zocweyo zokutofa ngesitofu somlilo.
Ezi ntlobo zintathu zingentla zokukhethwa kwezixhobo zokugaya amalahle zineenzuzo kunye nokungonakali, ekukhethweni kwezixhobo zokugaya amalahle, kuyimfuneko ukuqwalasela ukhetho olupheleleyo lwenkqubo yokugaya.Inkqubo yomgubo inokohlulwa ibe ziindidi ezimbini: uhlobo oluvuthela ngokuthe ngqo kunye nohlobo logcino oluphakathi (okubhekiselwa kulo njengohlobo logcino).Kwinkqubo yokuvuthuza ngokuthe ngqo, amalahle agutyungelwa abe lilahle elicoliweyo ngesisila samalahle aze avuthelwe ngqo kwiziko ukuze avuthe.Kwinkqubo yokugcinwa kwe-pulverization, amalahle ahlanjululweyo agcinwa kuqala kwi-bin yamalahle ehlanjululweyo, kwaye ngoko ngokweemfuno zomthwalo webhoyila, amalahle ahlanjululweyo athunyelwa ukusuka kumgqomo wamalahle ocoliweyo ukuya eziko ukuze atshiswe yi-pulverizer.Iinkqubo ezahlukeneyo zokucola ii-pulverizing nazo zifanelekile kwiindidi ezahlukeneyo zokukhethwa kwezixhobo zamalahle kunye namalahle.Ngokwenkqubo yokucoca, sishwankathele esi siseko silandelayo sokukhetha isisila samalahle:
(1) Intsimbi yentsimbi yokusila kumgqomo wogcino oluphakathi uhlobo lwenkqubo yomgubo womoya oshushu: ingasetyenziselwa i-anthracite (Vsr<9%) kwaye inxibe kwindawo eqinile ngaphezu kwamalahle.
(2) I-Mill Mill yogcino lwebhola uhlobo lokukhupha i-gas powder inkqubo yokuhanjiswa kwe-powder: ikakhulu isetyenziselwa amalahle ngokunxiba okunamandla kunye nokuguquguquka okuphakathi (Var-19% ~ 27%) amalahle e-bituminous.
.
(4) I-Medium-speed Medium-speed amalahle inkqubo yokuvuthela ngokuthe ngqo: ilungele ukusila amalahle e-bituminous kunye nomxholo ophezulu oguquguqukayo (Vanr-27% ~ 40%), umthamo ophezulu wokufuma (ukufuma kwangaphandle Mp≤15%) kunye nokunxiba okunamandla, kunye namalahle. ilahleko yobuxoki engaphantsi kokuqina, ukusebenza kokutsha kwamalahle kunokutsha, kwaye ukucolwa kwamalahle okucoliweyo kuhlangabezana neemfuno zomngqusho wamalahle.
(5) Inkqubo yokuvuthela ngokuthe ngqo kwesixhobo sokusila: ilungele ukhukuliseko lwe-lignite isalathiso sokunxiba i-Ke≤3.5 kunye ne-50 MW nangaphantsi kwebhoyila yeyunithi yamalahle ebhituminous
Ekukhethweni kwesixhobo sokugaya amalahle, kufuneka kuthathelwe ingqalelo ngokweempawu zokutsha, ukunxiba kunye neempawu zokuqhuma kwamalahle, iimpawu zokucolwa kwelitye lokusila kunye neemfuno zokucolwa kwamalahle, kudityaniswe nesakhiwo seziko kunye nesakhiwo somlilo webhoyila. , kwaye kuqwalaselwe utyalo-mali, ugcino kunye nenqanaba lokusebenza kweziko lombane kunye nezixhobo ezixhasayo, ukunikezelwa kweendawo ezisecaleni, umthombo wamalahle kunye nobutyobo kumalahle nezinye izinto.Ukuze kuphunyezwe umdlalo ofanelekileyo phakathi kwenkqubo yokucoca, isixhobo sokutsha kunye nesithando somlilo, ukuqinisekisa ukusebenza ngokukhuselekileyo kunye noqoqosho lweyunithi.Uomatshini be-HCM bukhethekileyo kwimveliso yabenzi bendawo yokusila ye-medium-speed, sivelisa uthotho lwe-HLM ye-medium-speed coal coal eneempawu ezilandelayo:
(1) Ukusetyenziswa kwe-roller enkulu kunye nediski, ukuxhathisa ukuqengqeleka kuncinci, iimeko zokungena kwamalahle zilungile, ngaloo ndlela kuphuculwe umthamo wemveliso, ukunciphisa ukusetyenziswa kwamandla.
(2) ukusebenza kokunciphisa kulungile, kukhuselekile kwaye kuthembekile;Ingxolo ehamba phantsi kunye nokungcangcazela;Ukusebenza kokutywinwa kulungile ukuqinisekisa ukuba umgubo wamalahle awungeni kuzo zonke iindawo ezijikelezayo zomatshini.
(3) Ilungele ukugawula amalahle aqinileyo, amandla okusila afanayo, ukusebenza kakuhle kokugaya.Ukusebenza okuzinzileyo nokuthembekileyo.
(4) Ukusila kwe-MPS akukho kwiindawo ezingasebenziyo, kwaye ukunxiba kwentsimbi kuncinci.Ukuba unengxaki yokukhetha izixhobo zokugaya amalahle, wamkelekile ukuba uqhagamshelaneHCM oomatshini for the basis of coal mill selection, contact information:hcmkt@hcmilling.com
