Kev ua haujlwm zoo ntawm biogas generators cia siab rau txoj kev siv cov txheej txheem uas suav nrog tag nrho cov saw hlau los ntawm cov khoom siv raw khoom mus rau cov khoom siv hluav taws xob. Lub hauv paus tseem ceeb ntawm txoj kev no yog nyob rau hauv kev sib txuas ntawm cov txheej txheem ntws, kev sib txuam ntawm kev xaiv cov khoom siv, thiab kev ua qauv ntawm kev ua haujlwm thiab kev tswj hwm. Tsuas yog nrog cov txheej txheem tsim nyog ntawm txhua theem tuaj yeem ua tiav qhov kev hloov pauv thiab siv lub zog biomass kom muaj kev nyab xeeb, ruaj khov, thiab muaj txiaj ntsig zoo.
Kev sau cov khoom nyoos thiab pretreatment yog thawj kauj ruam hauv kev siv. Cov khoom pov tseg uas tsim nyog, xws li cov tsiaj txhu thiab cov nqaij qaib, cov khib nyiab hauv chav ua noj, cov sludge hauv nroog, los yog cov qoob loo straw, yuav tsum tau txiav txim siab raws li cov peev txheej hauv cheeb tsam, thiab tsim kom muaj kev sib sau ua ke, kev thauj mus los, thiab kev khaws cia ib ntus. Ua ntej nkag mus rau hauv anaerobic digester, cov khoom siv raw yuav tsum tau ua raws li qhov tsim nyog ua ntej: cov khoom sib cais - kua sib cais tuaj yeem txhim kho slurry fluidity, crushing thiab homogenization tuaj yeem ua rau muaj kev sib cuag ntawm cov kab mob, thiab kev tshem tawm impurity thiab homogenization tuaj yeem tiv thaiv impurities los ntawm kev puas tsuaj rau cov khoom siv los yog cuam tshuam rau cov khoom siv roj. Rau siab-nitrogen lossis siab- cov khoom siv ntsev, cov pa roj carbon- nitrogen piv yuav tsum tau hloov kho los ntawm kev sib xyaw lossis kev faib ua feem kom ntseeg tau tias kev ua haujlwm ntawm lub zej zog microbial thiab tus nqi methanogenesis.
Tus yuam sij rau lub anaerobic digestion thiab cov roj sau cov theem yog tswj kom haum cov tshuaj tiv thaiv. Raws li cov yam ntxwv ntawm cov khoom siv raw, xaiv qhov nruab nrab- kub (35-38 degree) lossis siab- kub (55{10}}58 degree) txoj kev zom zaub mov, thiab muab nws nrog lub tshuab cua sov thiab ntsuas kub kom ntseeg tau tias qhov kub thiab txias hloov tau tswj nyob rau hauv ± 1 degree. Stirring txoj kev tuaj yeem suav nrog cov neeg kho tshuab nplawm, biogas recirculation, lossis dav hlau nplawm kom tswj cov khoom sib xws thiab tiv thaiv cov khib nyiab. Tus qauv tsim ntawm lub tshuab nqus tsev yuav tsum xav txog ob qho tib si lub sijhawm nyob hauv hydraulic thiab cov khoom siv thauj khoom kom tsis txhob muaj luv luv lossis thaiv. Cov biogas generated yog thauj mus rau lub purification chav tsev ntawm ib tug gas-kua separator thiab gas sau pipeline. Lub siab thiab ntws tus nqi yuav tsum tau tswj thaum lub sij hawm tus txheej txheem no kom txo tau cov roj to thiab ya raws condensation.
Gas purification thiab ruaj khov siab txaus yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev lag luam ntawm chav tsev. Cov biogas crude yuav tsum tau desulfurization (qhuav los yog ntub dej), lub cev qhuav dej, tshem tawm plua plav, thiab desiloxane tshem tawm cov txheej txheem kom ntseeg tau tias cov hydrogen sulfide concentration, dej cov ntsiab lus, thiab cov teeb meem me me ua tau raws li cov qauv ntawm cov roj nkag. Kev xaiv cov khoom siv purification yuav tsum xav txog cov pa roj ntws thiab cov pa phem kom txiav txim siab qhov chaw tsim nyog thiab lub sijhawm sib cuag. Cov biogas purified yog pressurized los ntawm ib tug compressor los yog blower thiab ces muab nyob rau hauv ib tug ruaj khov Circuit Court los ntawm lub siab regulating valve, flow meter, thiab kev nyab xeeb kaw -off valve, xyuas kom meej tas mus li thiab tswj combustion.
Kev tsim hluav taws xob thiab cov txheej txheem pov tseg hluav taws xob rov qab hais txog kev sib koom ua ke ntawm lub zog hluav taws xob thiab lub zog rov qab. Raws li qhov ntsuas thiab cov yam ntxwv thauj khoom, xaiv cov roj- hluav taws xob hluav taws xob sab hauv hluav taws xob, roj turbine, lossis lub tshuab hluav taws xob sab nraud, thiab muab nws nrog cov hluav taws kub, tswj ceev, thiab tawg- cov khoom pov thawj. Internal combustion engines yuav tsum tau ua tib zoo ua ke nrog siab -kub exchangers kom rov qab lub tog raj kheej liner cov dej thiab tso cov khib nyiab pov tseg thaum tshav kub kub digester cua sov los yog hauv cheeb tsam cua sov, tsim ib tug ua ke cua sov thiab lub hwj chim (CHP) qauv los txhim kho thawj lub zog siv. Lub kaw lus yuav tsum tau nruab nrog tsis siv neeg voltage tswj thiab daim phiaj kev sib txuas tswj cov cuab yeej los xyuas kom meej lub zog zoo thiab daim phiaj kev ruaj ntseg.
Cov kev saib xyuas kev ua haujlwm thiab kev tswj hwm txoj hauv kev hais txog cov ntaub ntawv - tau tsav kev ua kom zoo dua qub. Tsim kom muaj lub hauv paus saib xyuas qhov nruab nrab ntawm PLC lossis lub khoos phis tawj muaj peev xwm los sau thiab txheeb xyuas qhov kub thiab txias, siab, ntws tus nqi, roj muaj pes tsawg leeg, cov zis hluav taws xob, thiab cov ntsuas hluav taws xob hauv lub sijhawm. Tsim kev tshuaj xyuas, tu, thiab kho cov txheej txheem, tsom rau kev tiv thaiv corrosion, carbon buildup, thiab leakage txaus ntshai. Tsis tu ncua calibrate sensors thiab xyuas kom huv si efficiency los xyuas kom meej ntev - lub sij hawm ruaj khov system ua hauj lwm.
Kev nyab xeeb thiab kev tswj hwm ib puag ncig yuav tsum tau koom ua ke thoob plaws hauv tag nrho cov txheej txheem. Qhov no suav nrog kev teeb tsa cov pa hluav taws xob kom pom, kev saib xyuas nplaim taws, kaw thaum muaj xwm txheej ceev, thiab lub tshuab ua pa; tsim cov phiaj xwm xwm txheej ceev; thiab xyaum xyaum. Cov khoom tsim tawm biogas residue thiab slurry yuav tsum tau muab pov tseg tsis muaj teeb meem lossis siv los ua cov peev txheej, xws li los ntawm kev tsim cov organic chiv rau daim ntawv thov teb, yog li ua tiav qhov kaw - cov khoom siv kaw.
Hauv cov ntsiab lus, txoj kev siv cov tshuab hluav taws xob biogas yog ib qho kev qhia dav dav uas suav nrog cov khoom siv raw pretreatment, anaerobic digestion, roj purification, ua ke tsim hluav taws xob, kev soj ntsuam ntse, thiab kev ruaj ntseg. Tsuas yog los ntawm kev sib koom tes ntawm txhua theem tuaj yeem ua tiav cov hom phiaj ntawm kev siv hluav taws xob zoo thiab ua kom huv ntawm cov organic pov tseg.
