Yuav ua li cas siv lub tshuab xovxwm briquette los hloov sawdust rau hauv charcoal?

cov ntsiab lus

Hloov cov ntoo chips rau hauv charcoal siv lub tshuab briquette xovxwm yuav tsum nruj ua raws li peb kauj ruam tseem ceeb: pretreatment, molding, thiab carbonization. Kev tswj tsis tau ntawm txhua theem ncaj qha txiav txim siab qhov zoo ntawm cov charcoal. Thaum lub logic ntawm pretreatment thiab molding cov kauj ruam zoo ib yam li cov ntoo pellet mills ua pellet roj, cov qauv txawv.

Thawj kauj ruam yog ntoo nti pretreatment, uas yuav tsum tau ib txhij ua tau raws li qhov yuav tsum tau ntawm ob lub tshuab briquette molding thiab tom qab carbonization: cov ntoo chips yog thawj zaug crushed mus rau ib tug particle loj ntawm 2-8 hli, me ntsis ntau lenient tshaj 2-5 hli yuav tsum tau ntawm ib tug ntoo chip pellet zeb, tab sis loj hais yuav tsum tau zam kom tsis txhob sib txawv pwm. Cov dej noo yog tswj ntawm 8% -12%, qis dua 12% -15% haum rau cov ntoo pellet zeb. Cov dej noo ntau dhau tuaj yeem ua rau tawg tom qab molding thiab teeb meem xws li hlawv tsis tiav thiab charring thaum carbonization. Cov dej noo tuaj yeem hloov kho los ntawm huab cua kom qhuav lossis lub tshuab ziab me me. Ib txhij, impurities xws li pob zeb thiab hlau yuav tsum raug tshem tawm los ntawm kev tshuaj ntsuam xyuas kom tsis txhob muaj kev puas tsuaj rau lub tshuab briquette lub rollers thiab pwm.

Qhov thib ob kauj ruam yog briquetting, uas yog ib qho tseem ceeb nyob rau hauv bridging pretreatment thiab carbonization. Siv cov ntsia hlau extrusion xovxwm los yog hydraulic sawdust briquette xovxwm, preheat lub forming kab noj hniav rau 160-200℃ua ntej pib. Tom qab qhov kub thiab txias ruaj khov, pub cov khoom noj ua ntej- kho sawdust ntawm qhov sib txawv ceev rau hauv cov khoom noj. Nyob rau hauv kev kub siab (10-30MPa) los ntawm cov chais thiab tuag, cov lignin nyob rau hauv sawdust softens thiab melts, tsim ib tug natural binder, extruding nws mus rau hauv tuab lumps roj nrog ib txoj kab uas hla ntawm 20-50mm thiab ib tug ntev ntawm 5-20cm. Thaum lub sij hawm tsim, xyuas kom meej qhov ntom ntawm cov pob tiav tiav mus txog 1.1-1.3g / cm³. Tsis txaus yuav ua rau kom yooj yim tawg thaum lub sij hawm carbonization, txo cov yield. Cov kauj ruam no zoo ib yam li txoj hauv kev tsim cov ntoo pellet zeb, ob leeg tso siab rau lignin nws tus kheej khi; Txawm li cas los xij, lub siab thiab kub tswj ntawm lub tshuab briquetting yog nruj dua, thiab cov khoom tiav tiav yog siab dua li ntawm cov roj pellet.

Qhov thib peb kauj ruam yog carbonization, lub hauv paus ntawm hloov sawdust lumps rau hauv charcoal. Cov sawdust zoo li tus tau muab tso rau hauv qhov cub carbonization thiab carbonized nyob rau hauv peb theem: Qhuav theem (100-200 degree) tshem tawm cov seem seem kom tsis txhob tawg thaum lub sij hawm carbonization; pyrolysis theem (200-400 degree) decomposes volatiles (xws li methane thiab tar) nyob rau hauv sawdust, yuav tsum tau tswj cua sov npaum li cas los mus tiv thaiv ntau volatile tso tawm thiab ua rau overly ntxeem tau charcoal; carbonization theem (400-600 degree) tswj qhov kub thiab txias rau 2-4 teev kom ua tiav cov pa roj carbonization, tsim cov hluav taws kub nrog cov ntsiab lus siab ruaj khov. Tom qab carbonization, lub tshav kub qhov chaw raug muab tua, thiab cov charcoal raug tso cai kom txias ib txwm nyob rau hauv chav tsev kub los tiv thaiv high-temperature tiv tauj huab cua thiab tom qab combustion poob.

Tom qab ntawd, cov khoom siv hluav taws xob tuaj yeem raug crushed, tshuaj ntsuam xyuas, qib, ntim, thiab muag. High-kawg charcoal tuaj yeem ua polished ntxiv thiab zoo li tus nqi ntxiv. Piv rau cov ntoo pellet mills, charcoal briquette presses koom nrog ntau cov txheej txheem, tab sis tsim hluav taws xob nrog tus nqi calorific ntau dua (txog 6000-7000 kcal / kg), kev siv dav dua, thiab cov txiaj ntsig tseem ceeb dua.
