Cov lus qhia tseem ceeb rau Compressing Ntoo Chips nrog Lub Tshuab Me Me Biomass Briquette

Jan 23, 2026

Me ntoo chip briquette xovxwm tshuabtuaj yeem khov kho cov ntoo chips, tab sis cov kev hloov kho tshwj xeeb thiab kev kho kom zoo yuav tsum tau ua. Qhov no yog qhov yuav tsum tau ua ua ntej kom ntseeg tau tias kev ua tau zoo compression thiab qhov sib txawv tseem ceeb los ntawm cov txheej txheem ua ntej ntawm cov tshuab ntoo loj briquette.

Kev cuam tshuam

1. Hais txog particle me me adaptation, vim qhov me me tuag loj thiab tsis tshua muaj siab kis tau tus mob ntau yam ntawm cov khoom me me, cov ntoo nti particle loj yuav tsum tau tswj ntawm 2-8mm, nrog rau 3-5mm yog qhov zoo compression particle loj. Qhov no ua kom pom tseeb txaus thiab softening ntawm lignin thaum tsis txhob jamming thiab uneven molding tshwm sim los ntawm ntau particle loj. Yog hais tias cov ntoo chips loj dhau (tshaj 8 hli), qhov thib ob crushing nrog lub pulverizer me me yog tsim nyog; Yog hais tias cov khoom zoo dhau lawm (hauv qab 1 hli), nws yuav ua rau kom compression tsis kam, ceev cov khoom siv, thiab txo cov huab cua permeability ntawm briquettes.

2. Cov ntsiab lus noo noo yog qhov taw qhia tseem ceeb cuam tshuam rau compression efficiency. Qhov zoo tshaj plaws wood chip noo noo cov ntsiab lus ntau raume me ntoo shavings briquette txiag tshuabyog 8%-15%, nrog rau qhov zoo tshaj tus nqi ntawm ib ncig ntawm 12%. Thaum cov dej noo siab dhau lawm, cov sawdust yooj yim lo rau ntawm cov khoom noj thiab qhov tuag qhov, ua rau tawg, loosening, thiab txawm clogging ntawm cov cuab yeej thaum compression. Thaum cov dej noo tsawg dhau, cov lignin nyuaj rau soften txaus, uas ua rau briquette cohesion tsis zoo thiab yooj yim tawg. Thaum lub sij hawm pretreatment, ntub sawdust tuaj yeem ua rau huab cua qhuav lossis ziab hauv lub tshuab ziab me me. Rau qhuav sawdust, ib lub teeb tsuag dej tuaj yeem siv los kho cov dej noo; Cov txheej txheem yog tias "cov sawdust tuaj yeem clumped thaum nyem rau ntawm tes, tab sis yooj yim crumbles thaum tso tawm nrog lub teeb kov, tsis muaj qhov pom tseeb dej seem."

3. Lub purity ntawm sawdust yuav tsum nruj me ntsis tswj. Ua ntej compression, tawv impurities xws li pob zeb, hlau tawg, thiab iav yuav tsum tau muab tshem tawm. Cov impurities no yuav ua rau hnyav rau lub siab chais, qhov tuag qhov, thiab lwm yam tsis zoo ntawm qhov chawme me khib nyiab briquette tshuab, thiab tej zaum yuav ua rau lub ntsiab ncej khoov, cuam tshuam cov khoom siv lub neej. Nyob rau tib lub sijhawm, moldy thiab rotten sawdust yuav tsum tau muab tshem tawm. Hom sawdust no tsis tsuas yog txo cov nqi calorific ntawm briquettes tab sis kuj tseem tuaj yeem tsim cov ntxhiab tsw thaum lub sij hawm compression thiab cuam tshuam rau kev ua haujlwm combustion. Sawdust uas muaj me me ntawm cov tawv ntoo tuaj yeem raug compressed ncaj qha, tab sis cov ntsiab lus ntawm cov tawv ntoo yuav tsum tsis pub tshaj 10%, vim tias cov tawv ntoo ntau dhau yuav txo cov briquette ntom.

Tsis tas li ntawd, cov ntsiab lus fiber ntau ntawm cov ntoo chips kuj cuam tshuam cov nyhuv compression. Softwood (pine, fir) ntoo chips muaj cov ntsiab lus fiber ntau thiab zoo compressibility, ua rau lawv haum rau cov ntoo me me plua plav briquetting tshuab. Cov ntoo tawv ntoo muaj cov ntsiab lus qis dua me ntsis thiab tuaj yeem sib xyaw nrog 10% -20% sawdust los txhim kho cov khoom sib txuas. Pre-kho ntoo chips yuav tsum tau compressed kom sai li sai tau thiab khaws cia tsis pub dhau 24 teev kom tsis txhob muaj qhov nqus noo noo thiab ua kom cov compression efficiency thiab cov khoom zoo.me me ntoo chip briquetting tshuabnyob ruaj khov.
