Chithandizo cha ma VOC ndi kuyaka kochititsa chidwi

Ukadaulo woyaka catalytic ngati imodzi mwazinthu zopangira ma VOCs zinyalala za gasi, chifukwa cha kuyeretsa kwake kwakukulu, kutentha kocheperako (<350 ° C), kuyaka popanda lawi lotseguka, sipadzakhala zoipitsa yachiwiri monga m'badwo NOx, chitetezo, kupulumutsa mphamvu ndi kuteteza chilengedwe ndi makhalidwe ena, mu msika chitetezo ntchito ali ndi chiyembekezo chabwino chitukuko.Monga ulalo wofunikira waukadaulo wamakina othandizira kuyaka, ukadaulo wa catalyst synthesis ndi malamulo ogwiritsira ntchito ndizofunikira kwambiri.

1. Mfundo ya catalytic combustion reaction

Mfundo ya catalytic kuyaka anachita ndi kuti organic zinyalala mpweya kwathunthu oxidized ndi decomposed pansi pa zochita za chothandizira pa kutentha m'munsi kukwaniritsa cholinga kuyeretsa mpweya.Kuyaka kwa Catalytic ndikofanana ndi mpweya wokhazikika wa gawo lothandizira, ndipo mfundo yake ndi yoti mitundu ya okosijeni yokhazikika imatenga nawo gawo pakupanga okosijeni wakuya.

Mu chothandizira kuyaka ndondomeko, ntchito ya chothandizira ndi kuchepetsa kutsegula mphamvu zimene, pamene mamolekyu reactant ndi wolemera pa chothandizira padziko kuonjezera anachita mlingo.Mothandizidwa ndi chothandizira, mpweya wa zinyalala wachilengedwe ukhoza kuyaka wopanda lawi pa kutentha kocheperako ndikutulutsa kutentha kochulukirapo kwinaku oxidizing ndikuwola kukhala CO2 ndi H2O.

3. Udindo ndi chikoka cha VOCs chothandizira mu dongosolo kuyaka catalytic

Nthawi zambiri, kutentha kwamoto kwa VOC kumakhala kwakukulu, ndipo mphamvu yoyatsa ya VOC imatha kuchepetsedwa kudzera pakuyambitsa chothandizira, kuti muchepetse kutentha, kuchepetsa kugwiritsa ntchito mphamvu ndikusunga ndalama.

Kuonjezera apo, kutentha kwa moto kwa ambiri (palibe chothandizira) kudzakhala pamwamba pa 600 ° C, ndipo kuyaka kotereku kudzatulutsa ma oxide a nayitrogeni, omwe nthawi zambiri amanenedwa kuti ndi NOx, omwenso ndi oipitsidwa kuti aziyendetsedwa mosamalitsa.Kuyaka kothandizira ndi kuyaka popanda lawi lotseguka, nthawi zambiri pansi pa 350 ° C, sipadzakhala m'badwo wa NOx, chifukwa chake ndi otetezeka komanso okonda zachilengedwe.

4. Kodi liwiro la ndege ndi chiyani?Ndi zinthu ziti zomwe zimakhudza kuthamanga kwa ndege

Mu VOCs catalytic combustion system, kuthamanga kwa danga nthawi zambiri kumatanthawuza kuthamanga kwa voliyumu (GHSV), kuwonetsa mphamvu yogwiritsira ntchito chothandizira: kuthamanga kwa danga kumatanthawuza kuchuluka kwa mpweya wokonzedwa pa nthawi ya unit pa voliyumu ya chothandizira. Pazifukwa zina, chipangizocho ndi m³/(m³ chothandizira •h), chomwe chingathe kuphweka ngati h-1.Mwachitsanzo, mankhwala chizindikiro ndi danga liwiro 30000h-1: zikutanthauza kuti aliyense kiyubiki chothandizira angathe kupirira 30000m³ utsi mpweya pa ola limodzi.Kuthamanga kwa mpweya kumasonyeza mphamvu ya VOCs yopangira chothandizira, choncho imagwirizana kwambiri ndi ntchito ya chothandizira.

5. Ubale pakati pa katundu wamtengo wapatali wachitsulo ndi liwiro la mpweya, kodi zitsulo zamtengo wapatali zimakhala zapamwamba kwambiri?

Kuchita kwa chothandizira zitsulo zamtengo wapatali kumakhudzana ndi zomwe zili muzitsulo zamtengo wapatali, kukula kwa tinthu ndi kubalalitsidwa.Momwemo, chitsulo chamtengo wapatali chimabalalitsidwa kwambiri, ndipo chitsulo chamtengo wapatali chilipo pa chonyamuliracho mu tinthu tating'onoting'ono (nanometers angapo) panthawiyi, ndipo chitsulo chamtengo wapatali chimagwiritsidwa ntchito kwambiri, ndipo mphamvu yogwiritsira ntchito chothandizira ndi yabwino. zogwirizana ndi zitsulo zamtengo wapatali.Komabe, zitsulo zamtengo wapatali zikafika pamlingo wina, zitsulo zachitsulo zimakhala zosavuta kusonkhanitsa ndikukula kukhala tinthu tating'onoting'ono tokulirapo, kukhudzana ndi zitsulo zamtengo wapatali ndi VOCs kumachepa, ndipo zitsulo zambiri zamtengo wapatali zimakutidwa mkati. panthawiyi, kuonjezera zomwe zili muzitsulo zamtengo wapatali sikuthandiza kupititsa patsogolo ntchito zothandizira.
