Yuav Ua Li Cas Teeb Qhov Kub Zoo rau Biomass Wood Pellet Tshuab Raws Li Cov Khoom Siv Raw?

Dec 25, 2025

Ua ntej, cia peb qhia meej lub hauv paus ntsiab lus: lub hom phiaj ntawm kev kho qhov kub ntawm atsev siv pellet zeb ntoo pelletizeryog kom tag nrho soften lignin nyob rau hauv cov ntaub ntawv raw, tsim ib tug binder thiab xyuas kom meej pellet tsim.

Qhov ntsuas kub rau lignin softening feem ntau yog 70-110 degree. Cov ntaub ntawv nyoos sib txawv muaj cov ntsiab lus sib txawv lignin thiab hardness, yuav tsum tau hloov kho qhov kub thiab txias. Cia peb saib cov feem ntau softwood chips (pine, cedar). Cov ntaub ntawv nyoos no muaj cov ntsiab lus lignin siab thiab zoo adhesion, ua rau lawv yooj yim tshaj rau txheej txheem. Qhov kub ntawm 75-85℃yog txaus. Thaum kho, ua ntej teem qhov kub thiab txias rau 80℃thiab kuaj cov txheej txheem rau 10 feeb. Yog hais tias pellet nto yog du thiab hardness yog nruab nrab, tswj qhov kub thiab txias; Yog hais tias cov pellets yog xoob, nce qhov kub ntawm 5℃kom txog thaum lub pellets xav tau tiav.

Particle hom kev faib tawm

1. Cov ntaub ntawv nyoos no muaj qhov nyuaj siab thiab cov ntsiab lus ntawm lignin tsawg, yuav tsum muaj qhov kub thiab txias dua kom soften lignin. Nws raug nquahu kom kho qhov kub ntawm lub tshuab ntoo pellet rau 90-105 degree. Thaum ua cov ntoo tawv, qhov kub qis dhau yuav ua rau cov pellets xoob thiab ua rau tawg, thaum kub dhau heev yuav ua rau cov khoom siv raw rau carbonize, cuam tshuam rau kev ua haujlwm combustion. Tswv yim tswv yim: Ua ntej, teem qhov kub rau 95℃thiab soj ntsuam cov pellet tsim. Yog tias cov kab nrib pleb tshwm, qhov kub tsis txaus. Nce qhov kub ntawm 3℃txhua zaus kom txog thaum cov kab nrib pleb ploj. Tib lub sijhawm, ua kom cov menyuam ceev ceev kom paub meej tias cov khoom siv raw yog siab rhuab nyob rau hauv lub pressing chamber. Piv txwv li, thaum ua cov ntoo qhib sawdust, qhov kub thiab txias rau 98℃ua tiav qhov yuav tsum tau pellet hardness, thiab tus nqi calorific tuaj yeem ncav cuag ntau dua 4500 kcal / kg.

2. Rau straw raw cov ntaub ntawv (pob kws stalks, nplej straw), cov ntaub ntawv no muaj fiber ntau cov ntsiab lus thiab fluctuate ho nyob rau hauv cov ntsiab lus ntawm noo noo, yuav tsum tau ntau meej kub tswj. Nws raug nquahu kom tswj qhov kub ntawm 85-95℃. Thaum cov straw cov ntsiab lus noo noo siab (ze li 15%), qhov kub thiab txias tuaj yeem tsim nyog nce mus txog 95℃los pab cov dej noo sai sai. Thaum cov dej noo tsawg (qis dua 12%), Wood Chip Fuel Pellet Machine kub yuav tsum tau tswj ntawm 85-90℃kom tsis txhob kub siab ua rau fiber ntau embrittlement thiab cuam tshuam rau kev tsim pellet. Thaum hloov kho, xyuam xim rau kev pub mis ceev, tswj cov khoom noj qis qis kom tso cai rau lub sijhawm txaus kom muag muag hauv lub tshuab nias.

3. Kev tswj kub ntawm cov khoom sib xyaw ua ke: Yog tias ua tiav ntau yam khoom raw ib txhij, teeb qhov kub raws li cov khoom siv raw nrog qhov sib piv siab tshaj plaws, thiab tom qab ntawd zoo - kho nws raws li qhov xwm txheej molding. Piv txwv li, yog hais tias cov ntoo chips suav txog 70% thiab cov tawv ntoo chips account rau 30%, thawj zaug siv 80℃rau cov ntoo softwood ua lub hauv paus. Yog tias cov khoom me ntsis xoob tom qab kev sim ua tiav, nce qhov kub ntawm 5 degree. Cov lus ceeb toom tseem ceeb: Thaum hloov cov ntaub ntawv raw, ua ntej kho qhov kub ntawm lub tshuab hluav taws xob ca tuag pellet zeb rau qhov sib thooj, khiav nws rau 5 feeb kom tso cai rau qhov kub thiab txias kom ruaj khov ua ntej pub khoom noj, kom tsis txhob muaj qhov kub thiab txias uas yuav ua rau tsis ruaj tsis khov.
