Dab tsi yog cov thev naus laus zis tseem ceeb ntawm biomass pellet tshuab?

1. Raw khoom ua tshuab
Sau thiab pretreatment: Ua ntej ntawm tag nrho cov, lub tshuab biomass pellet yuav tsum tau sau ntau yam kev ua liaj ua teb thiab hav zoov pov tseg raws li raw cov ntaub ntawv, xws li ntoo chips, straw, mov husks, bark, thiab lwm yam. Cov ntaub ntawv raw feem ntau yuav tsum tau pretreated ua ntej nkag mus rau molding. cov khoom siv, xws li tshem tawm impurities, crushing, ziab, thiab lwm yam, kom ntseeg tau tias lub purity thiab tsim nyog lub cev ntawm cov ntaub ntawv raw.
Crushing thiab ziab: Cov khoom siv raw yog crushed rau hauv qhov loj me me los ntawm lub crusher, thiab tom qab ntawd cov ntsiab lus noo noo yog txo los ntawm cov khoom siv ziab, feem ntau xav tau cov ntsiab lus noo noo tsis pub tshaj 15%. Cov kauj ruam no yog qhov tseem ceeb rau cov txheej txheem molding tom ntej, vim tias cov dej noo ntau dhau yuav cuam tshuam rau molding zoo thiab combustion kev ua tau zoo ntawm cov khoom.
2. Moulding txheej txheem tshuab
Extrusion molding: Lub tshuab biomass pellet siv cov menyuam thiab lub nplhaib tuag rau extrude cov ntaub ntawv raw pretreated. Nyob rau hauv ib txwm kub kub, cov ntaub ntawv raw yog compressed rau hauv high-density pellet roj los ntawm kev kub siab. Hauv cov txheej txheem no, lub zog sib txuas ntawm cov khoom siv raw khoom tau txhim kho zoo heev los tsim cov khoom nrog lub zog tshwj xeeb.
Kev kho kub kub: Qee lub tshuab biomass pellet tseem yuav ua haujlwm kub kub ntawm cov pellets tom qab extrusion molding. Nyob rau hauv qhov kub thiab txias ib puag ncig, lignin thiab lwm yam khoom siv hauv cov khoom siv raw yuav tau txais cov tshuaj pyrolysis thiab polymerization, ntxiv dag zog rau cov pellets thiab txhim kho lawv cov nqi calorific thiab combustion efficiency.

3. Cov cuab yeej siv tshuab
Cov khoom tseem ceeb: Biomass pellet tshuab feem ntau yog tsim los ntawm kev pub mis, nplawm system, nias kaw lus thiab hluav taws xob tswj qhov system. Ntawm lawv, cov txheej txheem pub mis yog lub luag haujlwm rau kev sib npaug ntawm cov khoom siv raw pretreated rau hauv lub tshuab nias; lub tshuab nplawm yog siv los kho cov av noo thiab kub ntawm cov ntaub ntawv raw; cov txheej txheem nias yog qhov tseem ceeb, uas tsim cov ntaub ntawv raw rau hauv pellets los ntawm extrusion ntawm cov menyuam nias thiab lub nplhaib tuag; lub tshuab hluav taws xob tswj yog lub luag haujlwm rau kev tswj tsis siv neeg thiab kev saib xyuas tag nrho cov khoom siv.
Cov khoom siv ntawm cov khoom tseem ceeb: Lub nplhaib tuag thiab cov xovxwm cov menyuam yog cov khoom tseem ceeb ntawm lub tshuab biomass pellet, feem ntau yog ua los ntawm cov hlau zoo hlau lossis stainless hlau los xyuas kom meej nws hnav tsis kam, kub tsis kam thiab lwm yam khoom. Nyob rau tib lub sijhawm, kev tsim cov khoom siv no tseem yuav tsum xav txog lawv cov qauv kev tsim qauv thiab kev yooj yim ntawm kev saib xyuas.
