Cov Khoom Siv Khoom thiab Cov Txheej Txheem Ntau Lawm: Los ntawm Kev Tsim Nyog Ntuj Tsim Nyog rau Kev Kho Tshuab
Qhov tshwj xeeb ua tau zoo ntawm calcined anthracite stems los ntawm nws cov cim muaj pes tsawg leeg thiab cov txheej txheem ua kom zoo. Raws li cov pa roj carbon ntau tshaj plaws, anthracite inherently muaj cov txiaj ntsig zoo: ntau dua 90% cov ntsiab lus ruaj khov thiab tsawg dua 10% cov teeb meem tsis haum. Calcination ntxiv dag zog rau cov khoom no: cov ntsiab lus carbon ruaj khov nce mus rau ntau dua 92%, cov ntsiab lus tshauv tswj qis dua 6.5%, thiab cov ntsiab lus sulfur raug txo kom qis dua 0.3%, uas ua rau muaj siab -purity, ruaj khov carbon cov khoom nrog tsawg impurities. Nws qhov tseeb qhov ceev ncav cuag 1.82 ± 0.02, nrog hluav taws xob tiv thaiv ruaj khov ntawm 650 ± 30Ω・ hli. Cov kev ntsuas tseem ceeb no ua rau muaj kev ua tau zoo hauv hluav taws xob conductivity, thermal conductivity, thiab tshuaj stability.
Lub tshuab hluav taws xob calcination rauv yog cov khoom siv tseem ceeb rau kev ua tiav cov khoom siv hloov pauv no. Cov khoom siv thermal ua no siv cov khoom siv hluav taws xob los ua kom sov. Kev khiav hauj lwm ntawm kwv yees li 2000 degree, nws tshem tawm cov dej noo thiab cov khoom tsis zoo ntawm cov thee anthracite, muab cov khoom semi-graphitized rau cov khoom kawg. Nws cov qauv ntsug muaj xws li preheating, calcination, thiab txias zones. Ib qho hluav taws xob tam sim no tsim los ntawm sab sauv thiab qis electrodes pab txhawb kev txav mus los ntawm cov khoom siv raw hauv lawv qhov hnyav, ua tiav tag nrho cov txheej txheem calcination. Niaj hnub nimno hluav taws xob calcination furnaces feature automated tswj systems. Kev sib txawv - ceev tsav tswj tus nqi tso tawm, thaum lub tshuab tawm tswv yim tam sim no tswj hwm kev siv calcination, ua kom cov khoom zoo ib yam. Piv rau cov tsoos tank-hom calcination furnaces, hluav taws xob rauv muaj kev tswj qhov kub thiab txias, siab dua cov khoom purity, thiab yooj yim dua nruam ntau lawm, ua rau lawv lub ntsiab kev xaiv rau kev tsim high{11}} zoo calcined anthracite.
Raw khoom zoo decisively cuam tshuam cov khoom ua tau zoo kawg. Tuam Tshoj tus hwm anthracite cov peev txheej feem ntau faib hauv Shanxi, Henan, thiab Guizhou xeev, nrog Shanxi tuav 53.4% ntawm lub teb chaws reserves. Ntawm cov no, cov anthracite los ntawm Jincheng thiab Yangquan mining koog tsev kawm ntawv yog qhov zoo tshaj plaws. Ningxia's Taixi anthracite, nrog nws cov ultra- zoo tshaj plaws uas muaj cov hmoov tshauv hauv qab 5%, tau dhau los ua cov khoom siv tsis tshua muaj rau kev tsim cov hwm calcined anthracite. Cov pa roj carbon additives tsim los ntawm nws nthuav tawm cov nqi sib txawv hauv kev ua lag luam- cov khoom lag luam nrog 92% cov ntsiab lus carbon cov lus txib kwv yees li 100 yuan / ton tus nqi siab dua cov uas muaj 90% cov ntsiab lus carbon. Raw khoom pretreatment yog qhov tseem ceeb sib npaug. Ib ob-theem crushing thiab tshuaj ntsuam xyuas yuav tsum tau tswj cov thee particle loj nyob rau hauv lub 20-50mm ntau yam, kom ntseeg tau ib tug tsim nyog tus nqi siab tshaj 90% los lav qhov cub permeability thiab uniform combustion.
Daim ntawv thov Domains: Los ntawm Industrial Foundation rau Innovation Frontier
Daim ntawv thov toj roob hauv pes ntawm calcined anthracite txuas ntxiv txuas ntxiv nrog rau kev txhim kho kev lag luam, ua kom pom muaj txiaj ntsig ntau yam los ntawm kev sib sib zog nqus kev koom tes hauv cov khoom lag luam ib txwm muaj thiab kev ua tiav hauv cov xwm txheej tshwm sim. Kev lag luam steel tseem yog nws txoj kev lag luam loj tshaj plaws. Raws li lub tshuab hluav taws xob txhaj tshuaj roj thiab cov pa roj carbon ntxiv, calcined anthracite leverages nws cov pa roj carbon monoxide siab thiab tsis muaj impurity yam ntxwv tsis tsuas yog nce cov hlau kub kub tab sis kuj txo cov ntsiab lus sulfur, yog li txhim kho cov hlau zoo. Cov ntaub ntawv qhia tau hais tias thaum calcined anthracite tso nyiaj rau tsuas yog 3-5% ntawm raw khoom ib tuj ntawm steel tsim, nws boosts steel zog los ntawm 10-15%. Hauv kev lag luam tshuaj, nws ua haujlwm zoo rau cov khoom lag luam tsim khoom xws li calcium carbide thiab silicon carbide. Nws cov khoom siv tshuaj ruaj khov txhim kho cov tshuaj tiv thaiv yields thiab txo qis cov khoom tsim tawm.
Kev hloov pauv ntsuab hauv kev lag luam khoom siv hauv tsev tau tsim kev thov tshiab rau calcined anthracite. Hauv kev tsim cov txiv qaub kiln, calcined anthracite, nrog nws cov nqi calorific siab ntawm 5500-6500 kcal / kg thiab cov yam ntxwv ruaj khov combustion, tau hloov cov tsoos bituminous thee raws li cov roj nyiam. Nws ib puag ncig kom zoo dua ntawm cov ntsiab lus sulfur hauv qab 0.5% txo cov haujlwm ua haujlwm ntawm cov chaw desulfurization thaum txo cov sulfur impurity paug hauv cov khoom txiv qaub. Hauv kev tsim cov cement, "limestone-anthracite-limestone" txheej txheej pub noj tshuab optimizes kiln combustion efficiency, txo thermal noj los ntawm 8-12%.
Hla- cov ntawv thov kev lag luam hauv lub zog tshiab thiab kev tiv thaiv ib puag ncig tau tshwm sim los ua tus tsav tsheb loj hlob tshiab. Hauv kev tsim cov hydrogen, cov ntsiab lus carbon siab thiab cov yam ntxwv tsis zoo ntawm calcined anthracite ua rau nws zoo tagnrho gasification feedstock. Advanced thee gasification technologies tau txais txiaj ntsig zoo hloov nws mus rau hauv cov roj hluavtaws, ua kom muaj kev tsim cov siab -purity hydrogen. Hauv kev kho ib puag ncig, nws cov qauv pore ntau thiab thaj chaw loj tshwj xeeb ua rau nws ua tus neeg nqa khoom adsorbent zoo, ua kom pom cov pa phem tshem tawm hauv flue gas desulfurization thiab denitrification systems. Qhov tseem ceeb tshaj, nyob rau hauv biomedical teb, tshwj xeeb tshaj yog kho cov khoom siv roj carbon monoxide tau los ntawm calcined anthracite tau raug tshawb nrhiav siv los ua cov neeg nqa tshuaj thiab hauv cov ntawv thov kev lim ntshav, qhia txog kev hloov pauv zoo kawg li los ntawm cov khoom siv rau cov khoom siv.
