Vim li cas cov ntsiab lus noo noo tseem ceeb thaum siv Biomass Shredder?

Biomass shredders yog cov tshuab tseem ceeb hauv lub zog tauj dua tshiab, kev tswj cov khoom pov tseg, thiab kev lag luam ua liaj ua teb.Lawv txo cov khoom siv organic ntau ntau -xws li ntoo chips, qoob loo residues, hav zoov slash, thiab pov tseg ntsuab hauv nroog - mus rau hauv me me, cov khoom sib xws rau kev ua haujlwm ntxiv xws li pelletizing, composting, tag nrho cov kev hloov pauv uas cuam tshuam rau kev ua haujlwm shredder, ib qho sawv tawm raws li kev sib cav tshaj plaws: cov ntsiab lus noo noo.Kev nkag siab thiab tswj cov dej noo ntawm cov khoom noj khoom haus tsis yog qhov yooj yim xwb; nws cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub tshuab, kev nyab xeeb kev ua haujlwm, cov khoom zoo, thiab tag nrho cov nqi -effectiveness.
1.Shredding Efficiency thiab throughput
Cov ntsiab lus noo noo hloov pauv tus cwj pwm ntawm biomass.Thaum cov khoom ntub dhau (feem ntau tshaj 50-60% noo noo ntawm lub hauv paus ntub), nws ua mos, fibrous, thiab nplaum. Tsis txhob ua kom huv si nyob rau hauv lub shredder lub hammers los yog riam, ntub biomass raplump thiab smearing ib ncig, shafts.Qhov no ua rau:
• Txo cov dej ntws: cov khoom ntub dej txav qeeb dua los ntawm lub chamber, yuav tsum tau rov ua dua thiab ua kom lub sijhawm voj voog.
•Kev siv hluav taws xob ntau ntxiv: xav tau lub zog ntau dua los tsim kua muag es tsis yog snap fibers, nce nqi hluav taws xob ib tuj.
• Kev thaiv tsis tu ncua: Cov nplua ntub dej tuaj yeem ua rau ntawm cov ntxaij vab tshaus thiab cov chutes tawm, yuam kom tsis tu ncua sijhawm rau kev tu.
Conversely, qhuav heev biomass (qis dua 10% noo noo) ua nkig thiab plua plav.Thaum nws shreds yooj yim, nws generates ntau nplua particles uas yuav khiav dim los ntawm qhov khoob, txo yield thiab tsim huab cua los ntawm plua plav.
Qhov zoo tshaj noo noo ntau rau feem ntau biomass shredders nyob nruab nrab ntawm 15% thiab 35%, nyob ntawm seb lub tshuab tsim thiab lub hom phiaj particle loj. Nyob rau hauv lub qhov rais no, cov ntaub ntawv khaws cia txaus toughness kom huv si tsis sticking, maximizing ob leeg throughput thiab zog efficiency.
2. Cov khoom siv hnav thiab tu cov nqi
Cov dej noo ua haujlwm raws li cov roj nplua nyeem thiab cov tshuaj abrasive.High-cov dej noo feedstock accelerates corrosion ntawm hlau nto, tshwj xeeb tshaj yog yog hais tias lub biomass muaj acidic compounds (xws li, ntoo thuv koob, txiv hmab txiv ntoo peels). xeb thiab pitting degrade txiav ntug, cov ntxaij vab tshaus, thiab sab hauv liners, shortening tivthaiv lub neej. Ntxiv rau, kev txhawb nqa, shredder, uas ua rau muaj kev ntxhov siab tsis sib xws ntawm bearings thiab tsav siv.
Ntawm qhov tod tes, cov ntaub ntawv qhuav heev tsim cov silica zoo- cov hmoov av nplua nuj uas ua rau abrasive, hnav cov hammers, riam, thiab tshuaj ntsuam qhov ntawm qhov nrawm nrawm. Cov neeg ua haujlwm feem ntau tshaj tawm tias cov pob txha qhuav - straw qhuav los yog sawdust yuav tsum tau hloov rauj ob zaug ntau zaus raws li cov khoom siv ntawm 20% moisture.
Kev tswj cov dej kom zoo yuav txo tau tag nrho cov nqi txij nkawm los ntawm kev ntsuas cov kev sib tw no.Ntau tus neeg tsim khoom pom zoo ua ntej - cua txias feedstock nrog dej los yog cia ntuj ziab kom ua tiav cov dej noo zoo ib yam ua ntej pub rau lub shredder.
3.Safety Risks: Hluav taws kub thiab plua plav tawg
Tej zaum qhov kev xav txog kev nyab xeeb tseem ceeb tshaj plaws suav nrog kev sib raug zoo ntawm cov av noo thiab plua plav.Biomass plua plav yog combustible, thiab thaum tshem tawm hauv huab cua ntawm qee qhov kev xav, nws tuaj yeem ua rau tawg tawg. Cov khoom qhuav (cov dej noo qis dua 12%) ua rau cov plua plav ua pa ntau dua thaum lub sij hawm shredding, elevating qhov kev pheej hmoo ntawm hluav taws kub hauv lub tshuab los yog explosions.
Cov khoom ntub dej, thaum tsis muaj plua plav, qhia txog nws qhov kev phom sij: cov dej noo siab tuaj yeem ua rau lub zog tsim hauv lub shredder, ua rau lub siab tsim yog tias qhov cua tsis txaus. Tsis tas li ntawd, ntub biomass uas zaum hauv hoppers lossis conveyors rau lub sijhawm ntev tuaj yeem ua rau nws tus kheej - cua sov vim kev ua haujlwm ntawm microbial, muaj peev xwm ua rau muaj kev sib txuam.
Kev tuav cov dej noo siab tshaj 20% yog dav lees paub tias yog ib txoj hauv kev zoo los tiv thaiv cov plua plav thiab ua kom cov txheej txheem tsis pub dhau qhov txwv tsis pub muaj kev nyab xeeb.Ntau cov chaw tsim khoom nruab nrog cov ntsuas dej noo ntawm cov khoom noj thiab txiav txim siab kho cov tshuaj tsuag dej los yog sib tov kom nyob twj ywm saum toj no.
4.Downstream khoom zoo
Rau cov haujlwm uas siv shredded biomass li feedstock rau pellets, briquettes, los yog biogas digesters, cov ntsiab lus noo noo yog ib qho tsis yog -negotiable zoo parameter.
• Pelletizing: Pellet mills yuav tsum tau pub noo noo ntawm 8% thiab 14%.
•Combustion: Boilers thiab gasifiers ua tau zoo tshaj plaws nrog roj noo noo qis dua 30%.
• Composting: Aerobic decomposition ua hauj lwm zoo ntawm 40-60% noo noo.Yog hais tias cov shredder tso zis yog qhuav dhau lawm, lub compost pawg yuav tsis sov; ntub heev, thiab anaerobic hnab tshos daim ntawv, tsim odors.
Yog li, lub shredder yuav tsum xa ib tug zoo ib yam ntawm noo noo profile kom tau raws li downstream specifications.Variable feedstock ya raws quab yuam cov tswv rau tog twg los muab cov ntaub ntawv los yog ua lag luam nyob rau hauv ntxiv ziab / hydrating khoom, ntxiv nqi thiab complexity.
5. Kev cuam tshuam nyiaj txiag
Los ntawm kev xav txog nyiaj txiag, tsis quav ntsej cov ntsiab lus noo noo ua rau poob poob:
• Lub txim hluav taws xob: Txhua qhov feem pua ​​​​ntawm cov dej noo tshaj qhov zoo tshaj plaws ua rau muaj zog siv zog los ntawm kwv yees li 1-2%.
• Cov nqi qis qis: Cov tshuab txhaws thiab kho thaum muaj xwm txheej ceev tuaj yeem ua haujlwm ib nrab hnub.
• Tsis lees paub tus nqi: Tawm- cov khoom tshwj xeeb yuav tsum tau rov ua dua lossis muag ntawm tus nqi luv.
Ib qho kev nqis peev yooj yim hauv lub ntsuas dej ntim tau yooj yim thiab cov txheej txheem tswj cov dej noo yooj yim feem ntau them rau nws tus kheej hauv lub lis piam los ntawm kev txo qis hnav thiab txhim kho cov khoom siv.
Cov ntsiab lus noo noo tsis yog ib yam khoom ntawm cov khoom noj khoom noj xwb- nws yog cov txheej txheem sib txawv uas tswj xyuas seb biomass shredder coj li cas.Los ntawm kev siv tshuab thiab cov cuab yeej siv tau ntev mus rau kev nyab xeeb thiab cov khoom zoo kawg nkaus, txhua yam ntawm kev ua haujlwm yog cuam tshuam los ntawm ntau npaum li cas cov dej biomass tuav.Operators uas nquag saib xyuas thiab tswj kom zoo dua ntawm cov khoom lag luam, thiab kev pheej hmoo ntawm cov khoom lag luam decisive. tab tom khiav ua liaj ua teb me me- nplai chipper lossis cov kab kev lag luam shredding, kho cov dej noo raws li qhov tseem ceeb ntawm kev tswj xyuas yog thawj kauj ruam mus rau kev txhim khu kev qha, tau txais txiaj ntsig biomass.
