Yuav ua li cas qhov zoo ntawm cov khoom tiav yuav txhim kho los ntawm kev siv ntoo shavings briquette txiag?

cov ntsiab lus

Tom qab briquetting, cov chips ntoo yuav tsum tau carbonization meej kom hloov mus rau hauv siab - zoo charcoal. Tus yuam sij yog tswj qhov kub, cua sov, tuav lub sij hawm, thiab cov ntsiab lus oxygen ntawm biomass briquette xovxwm, ua tiav cov txheej txheem ntawm "tsawg- kub kom qhuav, nruab nrab- kub pyrolysis, thiab siab -kub carbonization," uas txawv kiag li ntawm cov ncej- ua cov ntoo pellet tsuas yog yuav tsum tau ua kom txias thiab tshuaj ntsuam xyuas. Kev tswj qhov kub thiab txias yog qhov tseem ceeb thiab yuav tsum muaj kev tswj xyuas meej nyob rau theem: Hauv theem ziab, qhov kub tau nce los ntawm chav tsev kub mus rau 100-200℃thiab khaws cia rau 1-2 teev kom tshem tawm 8% -12% ntawm cov dej seem ntawm cov ntoo chips. Cov cua sov tuaj yeem nrawm dua me ntsis hauv theem no (50-80℃ib teev), tab sis nws yog ib qho tsim nyog kom tsis txhob muaj cua sov hauv cheeb tsam uas tuaj yeem ua rau saum npoo ntawm cov ntoo kom qhuav thiab tiv thaiv kom tsis txhob ya raws sab hauv.

Thaum lub sij hawm pyrolysis, qhov kub nce mus rau 200-400 degree. Qhov no yog lub sijhawm tseem ceeb rau kev tso tawm cov teeb meem tsis hloov pauv (suav txog 60% -70% ntawm cov khoom hnyav, suav nrog methane, ethane, thiab tar) los ntawm sawdust. Cov cua kub yuav tsum tau qeeb mus rau 30-50℃ib teev, thiab cov teeb meem tsis haum xeeb yuav tsum tau muab tshem tawm tam sim ntawd kom tsis txhob muaj qhov sib txuam hauv cov pa roj carbonization, uas tuaj yeem ua rau combustion lossis tawg. Yog tias qhov kub thiab txias siab dhau lawm, qhov kev tso tawm sai sai ntawm cov teeb meem tsis zoo yuav tsim ntau qhov pores hauv cov hluav taws kub, txo nws lub zog; yog tias qhov kub nce qeeb qeeb, nws yuav ua rau lub voj voog ntau lawm thiab nce nqi zog. Thaum lub sij hawm no, lub cub tawg siab yuav tsum tau ua tib zoo saib xyuas thiab tswj ntawm ib tug me ntsis tsis zoo siab los txhawb kev tshem tawm ntawm volatile teeb meem.

Nyob rau theem carbonization, qhov kub nce mus rau 400-600℃thiab khaws cia ntawm qhov kub thiab txias rau 2-4 teev. Qhov no tso cai rau cov cellulose thiab hemicellulose nyob rau hauv sawdust kom tag nrho hloov mus rau hauv cov pa roj carbon monoxide. Qhov siab dua qhov kub ntawm lub sijhawm no, qhov siab dua cov ntsiab lus ntawm cov pa roj carbon monoxide thiab cov calorific nqi ntawm cov charcoal ntau dua. Txawm li cas los xij, qhov kub siab tshaj 600℃yuav ua rau kom cov hlwv ntawm cov hluav taws kub, ua rau nws yooj yim dua rau kev tawg. Lub sijhawm tuav yuav tsum tau hloov kho raws li qhov loj ntawm cov sawdust blocks; qhov loj ntawm txoj kab uas hla thiab qhov ntev ntawm qhov ntev, qhov ntev ntawm lub sijhawm tuav yuav tsum tau ua kom paub meej cov pa roj carbonization hauv lub cev thiab zam qhov "hlawv sab nraud, raw sab hauv" qhov xwm txheej. Piv nrog rau kev tsim cov roj pellet siv lub tshuab pellet ntoo, cov txheej txheem carbonization yuav tsum tau nqis peev ntxiv rau hauv qhov cub carbonization, uas ua rau muaj kev siv zog ntau dua thiab cov teeb meem kev lag luam, tab sis kuj tseem muaj txiaj ntsig ntxiv ntawm cov khoom tiav.

Tom qab carbonization, txias yog tsim nyog. Cov cua kub yuav tsum raug muab tua, cov roj carbonization cub tawg kaw, thiab cov hluav taws xob tso cai kom txias rau hauv chav tsev kub (kwv yees li 8-12 teev). Qhib lub qhov rooj rau lub qhov cub thaum txias yog nruj me ntsis txwv tsis pub huab cua nkag mus thiab ua rau cov hluav taws kub combustion poob. Tom qab txias, cov charcoal raug tshem tawm, deg impurities thiab khib nyiab raug tshem tawm, thiab nws raug tshuaj xyuas thiab muab qhab nia. Charcoal nrog cov ntsiab lus carbon ntawm 70% lossis siab dua yog suav tias yog siab-cov pa roj carbon zoo thiab tuaj yeem siv rau hauv siab-kawg daim ntawv thov xws li barbecues, metallurgy, thiab tshuaj. Cov hluav taws xob qis qis tuaj yeem ua rau pulverized thiab siv los ua cov roj ntxiv los txhim kho kev siv cov peev txheej.
