Kev soj ntsuam ntawm cov ntoo pellet tshuab Ntau Lawm Kab Kev Lag Luam
Cov txheej txheem tseem ceeb Flow ntawm Pellet Tshuab Ntau Lawm Kab
Lub tshuab pellet ua tiav cov kab ntau lawm feem ntau suav nrog rau rau theem tseem ceeb hauv qab no, txhua qhov sib txuas thiab ua haujlwm sib koom tes:
1.Raw khoom pretreatment (slicing/crushing).
Cov khoom siv raw yuav tsum tau ua tiav los ntawm chipper lossis pulverizer rau qhov loj me ntawm 3-5mm, uas yooj yim rau kev molding tom ntej. Piv txwv li, cov cav yuav tsum tau muab hlais thiab tom qab ntawd crushed, thaum straw yuav tsum tau txiav thiab tshem tawm ntawm impurities.
2. Kev kho kom qhuav
Cov dej noo ntawm cov ntaub ntawv raw yuav tsum tswj ntawm 10%-15%, siab dhau yuav ua rau cov khoom tsis tsim, thiab qis dhau yuav tawg. Nruas cua kub tshuab ziab khaub ncaws feem ntau yog siv rau lub cev qhuav dej, thiab qee qhov siab - kawg cov kab ntau lawm siv peb-theem kom qhuav txoj kev los txhim kho thermal efficiency los ntawm 28%.
3.Granulation molding (tub ntxhais txuas).
Lub pellet zeb yog "lub plawv" ntawm tag nrho cov kab ntau lawm, thiab lub ntsiab yog lub nplhaib tuag pellet zeb thiab tiaj tus tuag pellet zeb:
Lub nplhaib tuag tshuab yog tsim rau loj - teev tas mus li ntau lawm, nrog rau cov zis ntau txog 1-10 tons ib teev, siab particle ntom thiab du nto;
Lub tshuab pwm tiaj tiaj yog tsim rau me me thiab nruab nrab- qhov loj me lossis tsev neeg kev cob qhia, nrog kev nqis peev tsawg thiab kev saib xyuas yooj yim.
Thaum lub sij hawm pelletizing txheej txheem, cov khoom siv lub cev denaturation nyob rau hauv kev kub siab thiab kub, thiab tuaj yeem tsim tsis tau ntxiv cov binders.
4.Qhov txias thiab tshuaj ntsuam
Qhov kub ntawm cov pellets tshiab uas tsim tawm yog siab li 70-90 degree, thiab nws yuav tsum tau txias mus rau chav sov ± 5℃los ntawm counterflow txias kom tiv thaiv agglomeration. Tom qab ntawd, nws tau muab qhab nia los ntawm vibrating npo los cais cov khoom tsim nyog thiab cov hmoov los txhim kho cov txiaj ntsig.
5. Tsis siv neeg ntim
Cov khoom tiav tiav raug xa mus rau cov khoom tiav silo los ntawm lub thoob of elevator, thiab lub tshuab ntim tsis siv neeg ua tiav qhov hnyav, ntim, thiab sealing, txhawb nqa 25kg sachet lossis ton hnab ntim, uas txo cov nqi zog.
6. Kev tshem tawm plua plav thiab kev tiv thaiv ib puag ncig
Tag nrho cov kab yog nruab nrog cov khoom siv hluav taws xob cua daj cua dub, lub hnab tshem tawm cov plua plav thiab cov khoom siv txo suab nrov kom ua tau raws li "Kev Tshaj Lij Tshaj Lij Tshaj Lij rau Huab Cua" (GB 16297-1996) thiab ua tau raws li qhov yuav tsum tau ua ntawm kev ntsuas ib puag ncig.
