Yuav ua li cas yog txoj kev uas cuam tshuam rau lub sij hawm ntev ntawm cov khib nyiab incinerator, cia peb saib cov lus teb peb muaj rau koj hnub no.
1 feature ntawm incineration technology
Incineration yog ib qho cuab yeej siv rau cov tshuaj tiv thaiv ntawm cov khoom pov tseg hauv nroog ntawm qhov kub thiab txias, thiab tus nqi calorific ntawm pov tseg yog qhov tseem ceeb heev. Thaum ib tug txheej txheem tau mus txog, cov pov tseg yuav spontaneously combust thiab txuag lub zog, vim hais tias nyob rau hauv high kub, thaum lub combustible Cheebtsam nyob rau hauv cov khib nyiab reacts nrog huab cua, thaum lub calorific nqi mus txog ib tug tej yam nqi, tsis tas yuav ntxiv los yog. ntxiv ib qho me me ntawm cov roj pab. Qhov zoo dua ntawm MSW tom qab incineration yog txo, cov seem tom qab incineration tsuas yog 5% ~ 20% ntawm tus nqi qub, thiab cov khoom tsis zoo thiab tshuaj lom hauv cov khib nyiab yuav raug puas tsuaj thaum kub kub. Cov pa phem thiab cov khoom me me uas ua tom qab incineration tuaj yeem tso tawm tom qab raug kho los ntawm ib puag ncig purification cov cuab yeej, nrog kev ua kom tsis zoo, thiab cov roj flue uas tsim los ntawm incineration yuav ua rau kub kub lub zog thiab nqus B. Y boilers, uas tuaj yeem hloov mus rau hauv chav rau cua sov thiab tsim hluav taws xob, tuaj yeem rov siv lub zog.
2. Cov xwm txheej quo ntawm cov khib nyiab incineration
Nyob rau hauv cov ntsiab lus ntawm kev loj hlob hauv nroog, cov khoom khib nyiab hauv nroog feem ntau yog ua los ntawm cov tshuab grate incinerators thiab fluidized txaj incinerators. Kev tshawb fawb pom tias 90% ntawm cov teb chaws Europe yuav siv cov tshuab grate ntawm incineration nroj tsuag, khib nyiab incineration nroj tsuag. Nyob rau hauv txoj kev loj hlob ntawm peb lub teb chaws, 178 lub nroog cov khoom khib nyiab incineration fais fab nroj tsuag tau tsim nyob rau hauv 2014, siv cov cuab yeej siv tshuab pa. Muaj 67 lub chaw tsim hluav taws xob siv cov tshuab hluav taws xob fluidized, thiab cov nroj tsuag khib nyiab incineration nrog circulating fluidized txaj tshuab yog feem ntau faib nyob rau hauv cheeb tsam sab hnub tuaj, thiab feem ntau ntawm cov khib nyiab incineration nroj tsuag siv mechanical exhaust technology yog faib nyob rau hauv sab hnub tuaj ntug dej hiav txwv. Nyob rau tib lub sijhawm, nrog kev txhim kho me ntsis ntawm tib neeg lub tswv yim ib puag ncig, pyrolysis gasification tshuab tau siv dav hauv kev tiv thaiv ib puag ncig hauv xyoo tas los. Nws cov thev naus laus zis feem ntau suav nrog ob txheej txheem: pyrolysis thiab gasification. Pyrolysis tshuab yog feem ntau nyob rau hauv daim ntawv ntawm anaerobic los yog anoxic, los ntawm kev kub siab, siv cov organic teeb meem decompose nyob rau hauv daim ntawv ntawm pov tseg. Khoom coke txheej txheem ntawm volatile yam. Gasification feem ntau yog cov tshuaj tiv thaiv ntawm reactants nrog gasification nyob rau hauv lawv cov thawj lub xeev. Cationic cov neeg ua haujlwm, raws li lub hauv paus uas nws muaj peev xwm tsim cov txheej txheem ntawm kev hloov pauv thermal nrog cov pa roj.
