Muaj nuj nqi ntawm Txhua feem ntawm Biomass Pellet Ua Kab, theem los ntawm theem
Txoj kab ua ib txoj saw ntawm kev vam khom theem
Biomass pellet ua kab yog ib qho kev ua haujlwm tas mus li uas compresses hav zoov thiab kev ua liaj ua teb residue rau hauv pellet roj. Txawm li cas los xij, nws ua raws li tib 6 theem: crushing, ziab, pelletizing, txias, tshuaj ntsuam thiab ntim. Lub ntsiab lus tseem ceeb ntawm engineering yog tias cov theem no nyob ntawm, tsis yog sib npaug. Lub tshuab ziab khaub ncaws uas xa cov khoom ntawm 20% noo noo ua rau cov xovxwm tsis ua haujlwm; ib lub xovxwm uas ua rau cov pellets mos ua rau qhov screener tsim cov kwj deg uas yuav tsum tau rov ua dua lossis muag ntawm luv nqi.
| Theem | Muaj nuj nqi | Tswj parameter |
|---|---|---|
| Sib tsoo | Txo cov khoom siv raw rau qhov loj me me | 3mm rau 5mm |
| Qhuav | Tshem tawm cov dej ntau dhau ua ntej nias | 12% mus rau 15% noo noo |
| Pelletizing | Densify rau hauv 6 hli los yog 8 hli pellets | Tuag piv, kub, load |
| Txias | Teem lub pellet thiab txo qhov kub thiab txias | Tshem tawm ze ambient |
| Kev tshuaj ntsuam | Tshem tawm cov nplua thiab oversize | Mesh aperture, nplua sib koom |
| Ntim | Nyhav, lub hnab los yog bulk load | Hnab hnyav, bulk ntom |
1. Crushing System
Lub crusher hloov cov cav, ceg, slabs thiab offcuts rau hauv cov khoom me me kom tsim tau. Lub rauj zeb nrog lub vijtsam yog qhov kev teeb tsa ntawm me me thiab nruab nrab, thiab lub nruas chipper ua raws li lub rauj zeb yog ib txwm nyob qhov twg tag nrho cov cav lossis cov slabs loj yog pub. Screen aperture teem particle loj, ib txwm 3 hli mus rau 5 hli: ntxhib hais choj nyob rau hauv xovxwm feeder, thiab zoo heev hmoov av slips ntawm cov menyuam thiab tuag es tsis txhob raug nias. Crushing kuj homogenises pub, uas yog dab tsi ua rau tus so ntawm kab kwv yees.
2. Tshuab ziab khaub ncaws
Lub tshuab ziab khaub ncaws tshem tawm cov dej kom coj cov khoom mus rau hauv 12% mus rau 15% qhov rais. Ob hom yog siv. Lub tshuab ziab khaub ncaws ua haujlwm ua haujlwm lub teeb, cov khoom zoo nyob rau lub sijhawm luv luv thiab haum rau cov kab me me; lub tshuab ziab khaub ncaws ua haujlwm chunky, ntub dej pub thiab suits nruab nrab thiab loj tej yaam num. Lub tshuab ziab khaub ncaws yog qhov zoo tshaj plaws los tswj cov dej noo ntawm qhov paug tawm, tsis yog los ntawm qhov kub thiab txias ib leeg, vim cov khoom ntub dej sib txawv ntawm ib teev mus rau ib teev. Cov dej noo yog txiav txim siab los ntawm qhov cub txoj kev ntawm ISO 18134-3, thiab lub hom phiaj qhov rais tseem ceeb vim tias cov khoom hauv qab li 12% yuav tsis tsim cov lignin txaus, thaum cov khoom siab tshaj li 15% yuav tsis ncav cuag qhov kub thiab txias.
3. Pelletizing System
Cov xovxwm pellet yog qhov tseem ceeb ntawm txoj kab. Nws muaj cov feeder, qhov chaw txias qhov twg siv, cov tuag thiab cov menyuam, riam uas txiav pellets kom ntev, thiab lub tsheb ciav hlau tsav. Cov khoom yog nias los ntawm tapered tuag qhov; phab ntsa kev sib txhuam ua kom sov thiab rov qab - siab, thiab cov lignin daim ntawv cog lus. Tuag qhov compression piv, qhov zoo qhov ntev muab faib los ntawm lub qhov taub, yog qhov parameter uas tunes lub tshuab: softwood feem ntau nias ntawm li 1:5 txog 1:6, hardwood ntawm 1:7 mus rau 1:8. Kev tswj cov hloov pauv yog feeder tus nqi, tuag kub, lub cev muaj zog load thiab pellet ntev. Lub xovxwm khiav ntawm qhov load tsis tu ncua ua kom muaj zog sib xws; ib tug xovxwm khiav los ntawm on thiab off batching tsis.
4. Txias, kuaj thiab ntim
Cov pellets tawm hauv qhov tuag ntawm 70 C rau 90 C thiab mos. Lub txee-flow cooler coj lawv mus rau ambient cua kub nyob rau hauv lub sij hawm ntawm ob peb feeb; Yog hais tias pellets tau ntim nrog kub, lawv tawm hws hauv lub hnab, thiab cov condensate rhuav tshem cov kav ntev. Tus neeg tshuaj ntsuam ces cais cov nplua, uas tau muab rov qab rau hauv xovxwm, thiab ib qho loj dua. Ntim ua raws li qhov kawg kev ua lag luam: 15 kg lossis 20 kg hnab rau cov roj hauv tsev, lossis thauj khoom ntau rau hauv tipper lossis taug kev-cov tsheb hauv pem teb.
5. Kev Ntsuas thiab Kev Tswj Xyuas Zoo
Qhov zoo yuav tsum tau ntsuas, tsis xav. Cov txheej txheem ua haujlwm tau zoo ntawm cov kab pellet muaj cov dej noo ntawm cov khoom noj thiab cov pellet tiav rau ISO 18134-3, mechanical durability to ISO 17831-1, and the graded limits of EN ISO 17225-2, in which grade A1 wood pellets need not more than 10%. MJ / kg net calorific tus nqi, tsawg kawg yog 600 kg / m3 bulk ntom thiab tsawg kawg yog 97.5% mechanical durability. Cov ntaub ntawv xovxwm thauj khoom, sijhawm tuag thiab kav ntev ua ke yog qhov tso cai rau kev ua txhaum rau kev tuag, lub tshuab ziab khaub ncaws lossis cov khoom noj.
Cov lus nug nquag
Q:Lub sijhawm twg hauv kab pellet ua rau lub sijhawm poob qis tshaj?
A: Hauv kev xyaum, lub tshuab ziab khaub ncaws. Cov khoom ntub dej ntub dej sib txawv ntau dua li cov neeg muab khoom cog lus, thiab lub tshuab ziab khaub ncaws uas tsis zoo rau qhov phem tshaj - cov ntaub ntawv noo noo yuav txwv tsis pub tawm lossis dhau cov khoom ntub rau cov xovxwm, uas tom qab ntawd tsim cov pellets mos thiab nplua nyiaj siab.
Q:Lub crusher puas tuaj yeem tshem tawm?
A: Tsuas yog tias cov khoom nkag tau zoo ib yam nyob rau hauv 3 hli mus rau 5 hli, uas tsis tshua muaj sab nraum lub sawmill lossis cov rooj tog ntoo uas twb tau tsim cov sawdust. Chips thiab offcuts yuav tsum tau txo ua ntej nias.
Q:Dab tsi yog qhov haujlwm ntawm riam ntawm qhov tuag?
A: Lub riam teem pellet ntev los ntawm kev txiav cov extruded strand raws li nws tawm hauv qhov tuag. Ntev yog ib txwm khaws cia li ntawm 10 mm thiab 40 mm; ib tug blunt los yog phem teeb riam tsim ntev, curled pellets uas tawg nyob rau hauv tuav thiab nce nplua.
Q:Vim li cas cov pellets kub yog qhov teeb meem?
A: Cov pellets tawm ntawm qhov tuag mos ntawm 70 C rau 90 C. Yog tias lawv tau ntim ua ntej txias, noo noo condenses hauv lub hnab, durability tee thiab pwm tuaj yeem txhim kho hauv kev cia. Kev txias yog ib theem txheej txheem, tsis yog ncua sijhawm.
Q:Yuav tsum qhia tag nrho cov kab peev xwm li cas?
A: Qhia meej rau txhua theem rau tib qhov kev tsim tawm raws li cov dej noo tau hais tseg, feem ntau cov khoom tiav pellet tso tawm hauv tonnes ib teev ntxiv rau lub tshuab ziab khaub ncaws ntawm qhov phem tshaj - rooj plaub inlet noo. Ib kab tsuas yog ua tau raws li nws qhov tsawg tshaj plaws theem.
