Reactor los tsim cov roj av (Pyrolysis)

 

1) Cov yam ntxwv ntawm cov tshuaj tiv thaiv pyrolysis

Pyrolysis cov tshuaj tiv thaiv yog cov txheej txheem nyuaj uas cuam tshuam nrog cov khoom tawg ntawm cov khoom organic ntawm qhov kub thiab txias thaum tsis muaj oxygen. Cov tshuaj tiv thaiv no tuaj yeem ua tau nyob rau hauv ntau hom reactors, xws li fluidized txaj reactors, rotary kilns, thiab lub tshuab nqus tsev pyrolysis. Kev xaiv ntawm hom reactor nyob ntawm cov khoom noj tshwj xeeb thiab cov khoom xav tau.

 

Thaum lub sij hawm cov txheej txheem pyrolysis, cov khoom siv organic dhau los ntawm thermal degradation, ua rau tsim cov pa roj carbon monoxide, kua, thiab khoom char. Cov khoom no tuaj yeem ua tiav ntxiv kom tau txais cov tshuaj muaj txiaj ntsig, roj, lossis lub zog.

 

Ntxiv nrog rau qhov kub thiab txias siab, cov tshuaj tiv thaiv pyrolysis kuj tseem yuav xav tau cov huab cua tshwj xeeb los tswj cov theem ntawm cov pa roj thiab tiv thaiv cov kev xav tsis zoo. Tsis tas li ntawd, cov xov xwm corrosive tuaj yeem koom nrog hauv qee cov txheej txheem pyrolysis vim qhov xwm txheej ntawm cov khoom noj lossis cov tshuaj tiv thaiv ib puag ncig.

 

Cov kev ua haujlwm hnyav uas cuam tshuam nrog cov tshuaj tiv thaiv pyrolysis ua rau muaj teeb meem rau kev tsim khoom thiab xaiv cov khoom siv. Kub-kub corrosion kuj tseem ceeb heev rau kev tswj cov reactor kev ncaj ncees thiab ntev cov khoom siv lifespan. Tsis tas li ntawd, kev ntsuas kev nyab xeeb yuav tsum tau siv los txo cov kev phom sij uas cuam tshuam nrog kev tuav cov xov xwm corrosive thiab ua haujlwm nyob rau hauv ib puag ncig muaj kev kub ntxhov.

 

Zuag qhia tag nrho, kev nkag siab thiab kev tswj hwm cov yam tseem ceeb no yog qhov tseem ceeb rau kev txhim kho cov txheej txheem pyrolysis thiab ua kom muaj kev nyab xeeb hauv kev lag luam.

 

2) Cov khoom xaiv ntawm lub reactor

Kev kub siab ua haujlwm: Txij li cov tshuaj tiv thaiv pyrolysis yuav tsum tau ua ntawm qhov kub thiab txias, cov khoom siv reactor yuav tsum muaj qhov kub thiab txias. Stainless hlau, superalloy thiab lwm yam ntaub ntawv yog cov khoom siv kub resistant, uas tuaj yeem ua tau raws li qhov kub thiab txias ntawm cov tshuaj tiv thaiv pyrolysis.

 

Corrosion resistance: Corrosive media tej zaum yuav koom nrog cov tshuaj tiv thaiv pyrolysis, yog li cov khoom siv reactor yuav tsum muaj kev tiv thaiv corrosion zoo. Cov ntaub ntawv xws li stainless hlau thiab npib tsib xee-raws li alloys muaj corrosion kuj zoo heev thiab muaj peev xwm tiv taus corrosion ntawm corrosive xov xwm uas tej zaum yuav tsim nyob rau hauv cov tshuaj tiv thaiv pyrolysis.

 

Lub zog thiab ruaj khov: Pyrolysis cov tshuaj tiv thaiv tuaj yeem cuam tshuam nrog kev kub siab ib puag ncig, yog li cov khoom siv reactor yuav tsum muaj lub zog txaus thiab ruaj khov. Stainless hlau, siab alloy steel thiab lwm yam ntaub ntawv muaj lub zog thiab ruaj khov, thiab tuaj yeem tiv taus qhov kub siab ib puag ncig hauv cov tshuaj tiv thaiv pyrolysis.

 

3) Cov ntaub ntawv pom zoo thiab cov laj thawj

Xav txog cov yam ntxwv ntawm cov tshuaj tiv thaiv pyrolysis thiab cov khoom siv ntawm lub reactor, nws raug nquahu kom xaiv stainless hlau los yog superalloy ua cov khoom ntawm lub reactor. Nov yog vim li cas:

 

Stainless hlau: Stainless hlau muaj qhov kub thiab txias tsis kam, siab tiv taus thiab corrosion kuj, uas tuaj yeem ua tau raws li qhov kub thiab txias, siab siab thiab corrosive ib puag ncig yuav tsum tau ntawm cov tshuaj tiv thaiv pyrolysis. Nyob rau tib lub sijhawm, cov hlau tsis muaj steel kuj muaj cov khoom siv hluav taws xob siab, uas tuaj yeem xa tawm sai thiab sib npaug hauv cov txheej txheem tshuaj tiv thaiv.

 

Superalloys: Superalloys yog cov khoom siv tshwj xeeb tsim rau qhov kub thiab txias ib puag ncig thiab muaj qhov kub thiab txias tsis kam. Superalloys yog qhov kev xaiv zoo tshaj plaws rau cov tshuaj tiv thaiv pyrolysis ntawm qhov kub siab heev.

 

1. Raw khoom npaj

1) Cov ntaub ntawv raw khoom: Cov kev xaiv tseem ceeb ntawm cov khoom siv polyolefin, xws li polyethylene (PE), polypropylene (PP), thiab lwm yam, vim tias cov yas no yog tsim los ntawm olefins hauv roj av los ntawm cov tshuaj tiv thaiv polymerization, muaj peev xwm hloov tau siab.

 

2) Pretreatment: pretreatment ntawm yas raw cov ntaub ntawv, nrog rau kev tu, crushing, ziab thiab lwm yam kauj ruam kom tshem tawm impurities, txhim kho cov efficiency ntawm cov tshuaj tiv thaiv tom qab thiab cov khoom zoo.

 

2. Pyrolysis cov tshuaj tiv thaiv

1) Reaction txoj cai: Yas yuav rhuav tshem cov saw molecular ntawm qhov kub thiab txias, los ntawm cov molecules loj mus rau me me molecules, kom ua tiav qhov kev hloov ntawm cov khoom mus rau cov kua, thiab nrog rau cov tiam ntawm qee cov khoom gaseous. Ntawm lawv, C5H12-C11H24 thiab lwm yam khoom siv yog cov khoom tseem ceeb ntawm cov roj av.

 

2) Cov kev mob tshwm sim: Cov khoom siv yas yog muab tso rau hauv lub reactor, uas feem ntau yuav tsum tau ua nyob rau hauv ib qho chaw anaerobic lossis qis-oxygen ib puag ncig kom tsis txhob combustion ntawm cov yas. Cov tshuaj tiv thaiv kub yog feem ntau siab, feem ntau nyob rau hauv ntau pua pua degrees Celsius. Lub sij hawm cov tshuaj tiv thaiv nyob ntawm hom raw khoom, cov tshuaj tiv thaiv kab mob, thiab qhov zoo ntawm cov khoom yuav tsum tau.

 

3) Reactor xaiv: Vim qhov yuav tsum tau ua kom muaj qhov kub thiab txias thiab muaj peev xwm ua tau thaum lub sij hawm cov txheej txheem tshuaj tiv thaiv, lub reactor yuav tsum tau xaiv nrog kub thiab corrosion resistant cov ntaub ntawv, xws li stainless hlau, superalloy, thiab lwm yam. Tsis tas li ntawd, lub reactor yuav tsum muaj. zoo sealing thiab nplawm muaj nuj nqi los xyuas kom meej lub uniformity thiab efficiency ntawm cov tshuaj tiv thaiv.

 

3. Kev sib cais thiab kev huv

1) Gas-kua sib cais: Tom qab cov tshuaj tiv thaiv pyrolysis, cov khoom muaj xws li ob feem: roj thiab kua. Cov roj thiab kua yog sib cais los ntawm cov kauj ruam xws li condensation.

 

2) Distillation thiab rectification: Distillation thiab rectification ntawm cov khoom ua kua kom cais cov khoom sib txawv nrog cov ntsiab lus kub kub los tsim cov roj av thiab lwm yam khoom muaj txiaj ntsig (xws li, diesel, av wax, thiab lwm yam).

 

3) Lim thiab purification: Cov roj av tau lim thiab lim dej kom tshem tawm cov impurities thiab cov khoom tsis zoo thiab txhim kho qhov zoo thiab purity ntawm roj av.

 

4. Cov yam ntxwv ntawm cov khoom

1) Cov roj av zoo: Cov roj av tau los ntawm kev hloov pauv ntawm cov yas yuav qis dua qhov zoo dua li cov roj av uas tau los ntawm cov roj av ib txwm muaj, tab sis nws tuaj yeem siv los ua roj. Cov cim tseem ceeb xws li tus lej octane tuaj yeem ua kom zoo dua los ntawm kev kho cov tshuaj tiv thaiv kab mob thiab cov txheej txheem kho tom ntej.

 

2) Kev lag luam tus nqi: Cov txheej txheem ntawm kev hloov cov khoom pov tseg rau hauv cov roj av paub txog cov khoom siv rov ua dua tshiab, thiab muaj txiaj ntsig zoo. Tib lub sijhawm, cov txheej txheem kuj tseem pab txo cov pa phem ntawm cov pov tseg yas rau ib puag ncig.

 

Cov hauv qab no yog ib qho kev nug los ntawm cov neeg siv khoom hauv Asmeskas.

 

Kauj Ruam 1: Nws cov lus nug txog cov ntsiav tshuaj xovxwm: (Cov ntawv xiav yog peb cov lus teb).

 

Q1: Kuv xav tau lub reactor uas ua cov yas thiab hloov nws mus rau hauv roj av.

 

Stainless hlau reactor haum rau koj.
