Dab tsi yog qee qhov qis- nqi lwm cov khoom siv raw uas haum rau cov tshuab me me biomass pellet ua tshuab?

cov ntsiab lus

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov tshuab hluav taws xob ntoo pellet hauv kev tsim cov ntoo pellets yog lawv lub peev xwm los siv qis - cov khoom siv pov tseg. Dhau li ntawm cov sawdust thiab ntoo chips, ntau yam kev ua liaj ua teb pov tseg thiab cov khoom seem tuaj yeem siv los hloov, txo cov nqi thiab nthuav dav cov khoom siv raw. Ntawm cov khoom pov tseg ntawm kev ua liaj ua teb, straw (pob kws straw, nplej straw), txiv laum huab xeeb, thiab pob kws cobs yog tus nqi tshaj plaws - kev xaiv zoo. Cov ntaub ntawv no tau yooj yim muaj nyob rau hauv cov neeg nyob deb nroog, nrog tus nqi yuav tsuas yog 100-200 yuan / tuj, qis dua sawdust (300-400 yuan / tuj). Txawm li cas los xij, straw thiab peanut plhaub muaj cov ntsiab lus fiber ntau thiab xoob xoob, ua rau lawv nyuaj rau kev ua pellets ib leeg. Lawv yuav tsum tau tov nrog 20% -30% sawdust, thiab lub siab ntawm cov pellet zeb cov chais (nce mus rau 8-12MPa) thiab cov aperture tuag (xaiv li 8-10 hli) yuav tsum tau kho kom ntseeg tau tias pellet forming tus nqi thiab ceev raws li tus qauv.

Cov khoom siv hluav taws xob rau hluav taws xob ntoo pellet mills suav nrog cov rooj tog hauv tsev shavings, ntawv zeb pulp residue, thiab sawdust los ntawm board nroj tsuag. Cov ntaub ntawv no feem ntau yog kev lag luam pov tseg, nrog tus nqi qis qis, thiab qee qhov tuaj yeem tau txais dawb. Rooj tog Hoobkas shavings muaj siab purity thiab ruaj khov fiber ntau cov ntsiab lus, nrog compatibility zoo li ntoo chips, thiab yuav ua tiav ncaj qha los yog tov nyob rau hauv me me. Daim ntawv zeb pulp residue yuav tsum tau lub cev qhuav dej kom cov dej noo ntawm 12%-15% ua ntej muab sib xyaw nrog 15% ntoo chips kom tsis txhob muaj cov khoom xoob vim muaj fiber ntau zoo. Board cog sawdust yuav tsum tau kuaj xyuas kom tshem tawm cov kua nplaum- muaj cov impurities; ntshiab ntoo sawdust tuaj yeem ua tiav ncaj qha, muab cov nqi zoo heev.

Hauv nroog ntsuab pov tseg (pruned ceg thiab nplooj poob) kuj yog ib tug siab - zoo lwm yam raw khoom rau biofuel pellet tshuab. Nrog rau kev nthuav dav hauv nroog ntsuab, cov khoom pov tseg ntawm cov khoom pov tseg no tau nce, nrog cov nqi ua haujlwm tsawg thiab qhov chaw ruaj khov. Cov ceg yuav tsum tau crushed mus rau ib tug particle loj ntawm 2-5 hli, thiab poob nplooj yog tov nrog ntoo chips nyob rau hauv ib tug ratio ntawm 1: 2. Cov cellulose hauv nplooj poob txhim kho particle cohesion thaum txo cov nqi raw khoom. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khib nyiab ntsuab yuav tsum tau ntxuav kom huv si kom tshem tawm cov impurities, tiv thaiv cov pob zeb thiab cov hnab yas los ntawm kev sib kis ntawm cov ntoo pellet tshuab thiab ua rau nws puas.

Thaum siv cov khoom siv hluav taws xob tsawg- nqi qis, qhov tsis zoo ntawm biomass roj pellet tshuab yuav tsum tau hloov kho raws li cov yam ntxwv ntawm cov khoom siv raw. Yog tias tsim nyog, me me ntawm binder (xws li hmoov txhuv nplej siab los yog lignin hmoov) tuaj yeem ntxiv los txhim kho cov nyhuv pelleting. Nyob rau tib lub sijhawm, qhov kev faib ua feem ntawm lwm cov khoom siv raw yuav tsum tau tswj, tsis pub tshaj 70% ntawm tag nrho cov ntaub ntawv raw, kom ntseeg tau tias pellet tus nqi calorific thiab combustion kev ua tau zoo raws li cov qauv, ntsuas tus nqi thiab zoo.
