Peat yog ib qho khoom muaj nqis uas tsis muaj nuj nqis uas xwm tau muab rau tib neeg. Tib neeg tau siv peat ua biofuel txij thaum ub los. Nyob rau hauv lub ntiaj teb niaj hnub no, nws tau siv ntau yam, xws li tshuaj, biochemistry, kev ua liaj ua teb, tsiaj txhu, thiab lwm yam. Kab lus no piav qhia txog milled peat thiab nws cov thev naus laus zis extraction.

milled peat yog dab tsi?

Peat yog tsim los ntawm kev decomposition ntawm cov nroj tsuag nyob rau hauv tej yam kev mob ntawm tsawg cua nkag. Raws li txoj cai, nws tsim hauv thaj chaw swampy.

Milled peat yog cov pob zeb qhuav ntawm ntau cov duab thiab ntau thiab tsawg, tau los ntawm milling extraction. Qhov loj ntawm xws li peat ranges ntawm 5 mus rau 60 mm.

Cov muaj pes tsawg leeg ntawm milled peat suav nrog cov nroj tsuag fibers uas pab tswj qhov xav tau ntawm cov dej-cua sib npaug. Nws kuj muaj ntau cov as-ham thiab kab kawm (humic acids, poov tshuaj, magnesium, phosphorus, calcium, hlau, nitrogen), uas pab txoj kev loj hlob ntawm cov nroj tsuag.

Milled peat extraction technology

Txoj kev milling ntawm peat extraction yog txheej txheej los ntawm txheej txheej ntawm peat deposits. Cov txheej txheem thev naus laus zis yuav siv sijhawm luv luv thiab muaj cov kauj ruam hauv qab no:

• milling ntawm txheej txheej sab saud ntawm cov array - qhov no, nws yuav tsum tau txais cov khoom siv raw, qhov ziab ntawm qhov yuav tshwm sim feem ntau hauv cov huab cua tshwj xeeb;
• tedding ntawm txheej kho - muab loosening thiab qhov cua ntawm fossils, uas yog tsim nyog los txhim kho cov evaporation ntawm cov dej noo ntau dhau;
• dov qhuav raw cov ntaub ntawv - txheej txheem peat chips yog twisted rau hauv rollers;
• raw khoom sau thiab xa khoom xa tuaj;
• stacking rollers - koom nrog kev tshem tawm peat los ntawm lub tshuab sau qoob loo;
• cais ntawm peat - txheej txheem no yog xaiv tau thiab tsuas yog ua thaum tsim nyog.

Tom qab sau cov chais rau ntawm qhov chaw ntawm kev rho tawm cov thorium deposits, milling tshiab tau pib thiab lub voj voog thev naus laus zis tau rov ua dua raws li cov txheej txheem piav qhia. Rau ib lub caij tsim khoom, nyob ntawm cov huab cua puag ncig thiab cov yam ntxwv zoo ntawm cov txheej txheem dej, los ntawm 10 mus rau 50 lub voj voog tuaj yeem nqa tawm.

Ua ntej milling, cov chaw ua haujlwm yuav tsum tau npaj. Ua li no, cov array yog drained, nws yog ntxuav los ntawm woody thiab grassy zaub.

Kev rho tawm ntawm peat chips los ntawm milling txawv los ntawm lwm txoj hauv kev hauv kev ziab kom qhuav ntawm qhov tso nyiaj, tus nqi qis thiab kev siv zog ua haujlwm, lub voj voog siv tshuab luv luv thiab qib siab ntawm kev siv tshuab.

Nyob milled peat

nyob ntawm qhov tobtshwm sim qhov txawv ntawm high-moor thiab low-moor peat. Raws li qhov kev ntsuas no, milled peat yog cais. Txhua hom sib txawv ntawm qhov muaj pes tsawg leeg, cov khoom thiab cov yam ntxwv zoo. Cia peb nyob ntawm lawv txhua tus kom ntxaws ntxiv.

High milled peat

roob-hom peat raw cov ntaub ntawv yog tsim los ntawm cov seem ntawm cov nroj tsuag. Nws yog tsim los ntawm conifers thiab moss. Hom peat no yog tus cwj pwm los ntawm qhov muaj peev xwm ntawm cov dej noo siab, uas yuav pab tswj tau qhov zoo ntawm huab cua thiab dej hauv av. Qhov no tseem ceeb heev rau kev loj hlob ntawm cov nroj tsuag. Tab sis vim tsis muaj cov ntxhia muaj txiaj ntsig zoo thiab cov ntsiab lus tsis tshua muaj tshauv, high-moor milled peat yog cov chiv tsis muaj zog. Tsis tas li ntawd, nws yog tus cwj pwm los ntawm qhov qis qis ntawm decomposition, uas tsis muaj qhov tseem ceeb tsawg rau cov khoom noj cog qoob loo nrog cov khoom muaj txiaj ntsig.

Cov xim ntawm milled high-moor peat yuav hloov nrog nce decomposition feem pua ntawm lub teeb daj mus rau xim av.

Peat lowland milling muaj xim av tsaus lossis xim dub. Nws yog tus cwj pwm los ntawm qib siab ntawm decomposition thiab muaj ntau yam tseem ceeb. Tsis tas li ntawd, cov chaw qis qis yog moistened los ntawm dej nyab thiab dej hauv av, uas yog qhov chaw ntawm calcium.

Av peat muaj qhov nruab nrab lossis me ntsis acid alkaline cov tshuaj tiv thaiv.

Zoo-decomposed peat ntawm cov khaubncaws sab nraud povtseg yog tsaus xim thiab muaj cov organic teeb meem tseem ceeb - humus. Nws muaj txiaj ntsig zoo nyob rau lub sijhawm ntev ntawm cov qauv ntawm cov av, ua kom nws cov qoob loo.

Qhov twgPuas yog milling hom peat siv?

High milled peat yog lub hauv paus zoo rau tsev cog khoom av. Nws cov yam ntxwv piv ntawm huab cua thiab noo noo muaj peev xwm pab tsim kom muaj dej siab nyob rau hauv cov hauv paus hniav txheej txheej hauv av kaw. Vim li no, high-moor peat yog siv rau kev loj hlob strawberries, ntau yam seedlings, thiab paj. Nws tsis muaj cov noob nroj tsuag, kab tsuag thiab ntau yam kab mob, uas pab txhawb kev siv peat hauv tsev cog khoom thiab tsev cog khoom. Tsis tas li ntawd, nws yog siv rau hauv kev ua liaj ua teb ua cov ntaub pua chaw pw hauv qhov chaw uas cov nqaij qaib thiab tsiaj khaws cia. Qhov tseeb yog tias cov peat zoo kawg nkaus ntxuav cov huab cua ib puag ncig thiab pab tiv thaiv ntau yam kab mob txaus ntshai. Yog li, peat sab saum toj tsis yog tsuas yog siv tau, tab sis kuj muaj kev nyab xeeb heev.

Tsis tas li, caij-hom peat tau pom nws daim ntawv thov hauv kev lag luam. Yog li, nws feem ntau yog siv los ua lim dej hauv cov nroj tsuag kho.

hom peat tsawg tau pom daim ntawv thov dav. Yog li, nws cov kev taw qhia rau hauv cov av tau txhim kho cov yam ntxwv ntawm cov av xws li ntom, porosity, muaj peev xwm noo noo, khoom noj khoom haus thiab microbiological muaj pes tsawg leeg. Kev siv cov peat no pab txo cov nitrates hauv cov qoob loo cog qoob loo 2-3 zaug.

Feem ntau, lowland peat yog siv los fertilize marginal xau kom saturate lawv nrog cov khoom muaj txiaj ntsig. Nws tseem tso cai rau koj los khi cov xuab zeb xoob av thiab loosen ntom av nplaum av. Vim nws cov khoomlowland peat tiv thaiv cov av los ntawm ziab tawm thiab khaws cia ib theem txaus ntawm noo noo, uas ua rau kom cov qoob loo ntawm cov nroj tsuag zus. Kev sau qoob loo zoo tuaj yeem tau txais los ntawm kev loj hlob qos yaj ywm, ntau yam zaub thiab berries hauv peat av.

Cov av qis yog lub hauv paus zoo heev rau kev ua compost. Txhawm rau ua qhov no, sib tov straw, quav, khib nyiab hauv tsev, potash thiab phosphorus chiv nrog peat crumbs.

Milling peat yog siv dav heev rau kev tsim cov briquettes. Peat qiv nws tus kheej zoo rau cov txheej txheem no thiab tsis xav tau kev khi ntxiv. Cov briquettes no yog siv rau cov cua sov hauv tsev thiab chaw ua haujlwm.

Tus nqi ntawm milled peat

Nyob rau hauv cov xwm txheej niaj hnub no, ntau lub lag luam yuav milled peat. Tus nqi rau nws nyob ntawm lub cev thiab tshuaj lom neeg ntawm cov array thiab cov txheej txheem nyuaj. Yog li, nees peat yog pheej yig dua. Cov nyiaj khaws cia nyob rau hauv qhov tob zoo yog suav tias muaj nuj nqis heev thiab muaj ntau yam haujlwm. Qhov taw qhia tseem ceeb uas txiav txim siab seb qhov chaw qis milling peat yuav raug muag li cas yog tus nqi. Kev siv peat rau ntau lub hom phiaj ncaj qha cuam tshuam qhov nce hauv kev tsim khoom. Qhov no txhawb txoj kev loj hlob ntawm peat kev lag luam thiab kev lag luam tag nrho.
