Txoj Kev Ua Haujlwm
Ua kom cov kuab tshuaj laden cua (SLA) ntau dua qhov kub ntawm 750-800 ° C, cov txheej txheem no tso cai rau cov cua sov rov qab ua tsaug rau cov khoom siv ceramic.Txhua regenerative chamber muaj ib tug ceramic matrix, uas, nyob ntawm seb cov kev taw qhia ntawm ntws, absorbs tshav kub los ntawm cov pa khib nyiab tom qab combustion los yog preheats cov huab cua ua ntej combustion.Raws li cov pa paug paug, cov nroj tsuag tuaj yeem siv 3 lossis 5 tus yees.Cov txheej txheem ntws los ntawm lub txaj hauv ib lub chamber uas tau preheated thaum lub voj voog dhau los;Lub txaj preheats huab cua nyob ze rau qhov kub thiab txias, kwv yees li 800 ° C, thiab lub sijhawm no qhov kub ntawm lub txaj poob sai heev.Qhov kub combustion yog tswj los ntawm cov cua kub uas tsim los ntawm oxidation ntawm VOC's los yog, yog tias VOC concentration tsawg, los ntawm kev ntxiv roj.Cov roj khib nyiab los ntawm lub combustion chamber ntws los ntawm lub txaj hauv lwm chav uas cov ceramic matrix absorbs cua sov los ntawm cov roj, ua ntej tso tawm mus rau pawg.Lub tshav kub absorbed los ntawm lub txaj nyob rau hauv lub qhov hluav taws xob chamber yog ces siv los preheat cov cua tuaj nyob rau hauv lub tom ntej no voj voog.
Lub sijhawm nruab nrab ntawm lub voj voog sib txawv ntawm 60 mus rau 120 vib nas this nyob ntawm qhov xwm txheej thiab qhov xav tau ntawm tus kheej cov kab mob.Lub chamber thib peb tso cai rau kev kho ntxiv ntawm cov huab cua pov tseg, uas qhov ntws rov qab tiv thaiv kom tsis txhob nyob hauv chav combustion ntawm qhov kub thiab txias rau lub sijhawm tsim nyog.Txhawm rau kom tsis txhob muaj cua sov ntau dhau ntawm cov thermal oxidizer thaum muaj qhov siab ntawm cov kuab tshuaj tshwm sim, siv cov kub bypass tawm cov dej kub ncaj qha los ntawm combustion chamber.Cov kwj deg no ntawm 900 ° C tuaj yeem siv ua piv txwv los ua kom sov cov roj thermal, dej los yog tsim cov pa.
