Ngokuhambela phambili kwemizi-mveliso kunye nokukhula kwezixeko, ulawulo lwee-volatious organic compounds (ii-VOC) aluzange lube lukhulu kangako. Ii-VOCs ngokupheleleyo zivela kwimizi-mveliso, kwizakhiwo ze-petrochemical, kwii-paint booths, nakwii-printers azinabungozi kwimpilo yabantu kuphela kodwa nakwindalo esingqongileyo. Ngoko ke amashishini asebenzisa indlela esebenzayo.Iinkqubo zokucoca i-VOCnjengenkqubo ebalulekileyo ekususweni kongcoliseko lomoya olubi kunye nokungenelela kwemithetho ekupheliseni loo ngxaki.

Ukufunda ngee-VOC kunye neempembelelo zazo

Ii-VOC zizinto eziphilayo eziguquguqukayo ezinoxinzelelo lomphunga ophezulu kubushushu obuqhelekileyo begumbi kwaye ngenxa yoko ziyaphela ngokulula emoyeni. Eminye yemizekelo edumileyo yee-VOC ibandakanya izinto zokugquma, izincamathelisi, izinyibilikisi, kunye namafutha. Ukuvezwa ixesha elide kwii-VOC kunokubangela isifo sokuphefumla, intloko ebuhlungu, kunye nemiphumo yexesha elide efana nomonakalo wesibindi kunye nezintso. Ngaphandle koku, ii-VOC zikwavelisa i-ozone kunye ne-smog esezantsi komhlaba kwaye ngaloo ndlela zikhokelela ekonakaleni kokusingqongileyo.

Ezi mpembelelo kufuneka zincitshiswe ngezisombululo ezifanelekileyo zegesi yenkunkuma ye-VOC kumashishini, ukuze ukukhutshwa komoya kuphathwe ngokufanelekileyo xa kuveliswa ukuze kuthintelwe umkhondo wazo kwindalo esingqongileyo.

Iinkqubo zokuCoca i-VOC: Isishwankathelo sobuGcisa

Iinkqubo ezahlukeneyo zokucoca i-VOC zinokunyanga iintlobo ezahlukeneyo ze-VOC kunye namanqanaba oxinzelelo lwegesi. Ezi nkqubo ngokubanzi ziya kuquka ezi teknoloji zilandelayo:

1. Ii-oxidizers ezishushu

Ezi nkqubo zitshisa ii-VOC kumaqondo obushushu aphezulu, zize ziwachithe zibe ngumphunga wamanzi ongenabungozi kunye ne-carbon dioxide. Ii-oxidizers ezisebenzisa ubushushu zisetyenziswa kakuhle kwi-VOC emissions ephezulu kwaye zaziwa ngokuthembeka kwazo nokusebenza kwazo kakuhle.

2. Ii-Catalytic Oxidizers

Ngokusebenzisa ithuba lokusetyenziswa kwe-catalyst ukukhuthaza i-oxidation kumaqondo obushushu aphantsi, ii-catalytic oxidizers ziyilo ezonga amandla xa kuthelekiswa neenkqubo zobushushu. Zifanelekile ukusetyenziswa kwizicelo ezibandakanya amanqanaba aphantsi oxinzelelo lwe-VOCs.

3. Iinkqubo zokufunxa ikhabhoni esebenzayo

Ii-activated carbon filters zisetyenziswa rhoqo kwiIzicoci zegesi yenkunkuma ye-VOC, ingakumbi kwiingxolo ezikhutshwayo ezinoxinzelelo oluphantsi. Ikhabhoni esebenzayo iyasebenza ekufunxeni iimolekyuli ze-VOC ngenxa yendalo yayo yokuba neembobo kwaye yindlela engabizi kakhulu kwaye ayidingi kulungiswa kakhulu.

4. IiYunithi zokuFunxa kunye nokuFunxa

Ezi yunithi zisusa ii-VOC kwimithombo yegesi ngokusebenzisa utshintsho lobushushu okanye izinyibilikisi zeekhemikhali. Zisetyenziswa rhoqo xa zidibene nezinye iiteknoloji zokucoca ukongeza ubuchwepheshe.

Iindlela ezahlukeneyo zokucoca ziyafumaneka, nganye ineenzuzo ezikhethekileyo ezisekelwe kushishino, indlela yokukhupha ukungcola, kunye nemigaqo.

Ukukhetha ii-VOC Waste Gas Purifiers ezifanelekileyo

Ukukhetha izicoci zegesi yenkunkuma ze-VOC ezifanelekileyo kubalulekile ekusebenzeni kakuhle nangokuhambelana nokusingqongileyo. Nazi izinto ekufuneka ziqwalaselwe:

1. Uhlobo kunye noxinzelelo lwe-VOC

I-thermal oxidation ingasetyenziselwa ukukhupha ubushushu obuphezulu, kunye neenkqubo zokufunxa ubushushu obuphantsi.

2. Umthamo womoya

Izixhobo zoshishino zifuna izixhobo ezinzima ezinomthamo ophezulu.

3. Ukusebenza kakuhle kwamandla

Ukusetyenziswa kwamandla yindleko enkulu yokusebenza; ngoko ke, iiyunithi zokubuyisa ubushushu okanye iiyunithi ezincediswa yi-catalyst ziya kunciphisa iindleko zokusebenza.

4. Iindleko zolondolozo kunye nokusebenza

Izixhobo ezifudukayo ezincinci kunye neeyunithi ezizicocayo zinganciphisa ixesha lokungasebenzi kunye neendleko zokulungisa.

Ngokuphonononga ngononophelo ezi ndlela, iimfuno zesibonelelo zinokudityaniswaIzisombululo zegesi yenkunkuma ye-VOC.

Ukuhlanganiswa kwiiNkqubo zoLondolozo oluLungileyo

Kwaye enye indlela entsha yokulawula ukukhutshwa kwe-VOC kwimizi-mveliso kukudibanisa iinkqubo zokucoca i-VOC kunye netekhnoloji yokubeka esweni ngobuchule. Ezi nkqubo ziquka izinzwa kunye nokucubungula ukujonga ukukhutshwa kwe-VOC ngexesha langempela, ukulungisa ngokuzenzekelayo iiparameter zokusebenza, kunye nokubonelela ngokusebenza kokucoca rhoqo. Oku akupheleli nje ekwandiseni ukusebenza kakuhle kodwa kukwabonelela ngamaxwebhu okuhlolwa kwendalo kunye nokuthotyelwa kwemithetho.

Ukuthotyelwa kweeMfuno zoLawulo kunye neeNjongo zoZinzo lweShishini

Imithetho kwihlabathi liphela, kwimeko yamazwe afana ne-US Environmental Protection Agency (EPA), i-European Union, kunye noorhulumente bamazwe ase-Asia, iya isiba yimithetho eqinileyo yokukhupha i-VOC. Ukungathobeli imithetho kukwatsala izigwebo ezinkulu kunye nomonakalo wegama. Utyalo-mali kwizixhobo zokucoca igesi ze-VOC zokwenyani alukhuseli nje kuphela iinkampani kuxanduva kodwa lukwanceda ekuxhaseni amaphulo okuzinza kwenkampani.

Ngaphezu koko, uninzi lweenkampani zisebenzisa iindlela zokulawula i-VOC njengecebo lokuthengisa kunye nokubonisa. Ukuze zixhalabele umoya ococekileyo, ubomi obusempilweni, kunye neenkqubo zemveliso ezinobuhlobo nokusingqongileyo.

Isiphelo

Kwihlabathi lemveliso elinobuhlobo nokusingqongileyo, izicoci zegesi yenkunkuma ze-VOC aziseyonto yokuziyolisa, kodwa ziyimfuneko. Xa imveliso ifunwa ngokusebenzisa uluhlaza, iinkqubo zegesi yenkunkuma ze-VOC ezisebenzayo zezona ndlela zifanelekileyo. Ngokusebenzisa izicoci zegesi yenkunkuma ezishushu, iinkqubo ze-catalytic, okanye iinkqubo ze-adsorption, izicoci zegesi yenkunkuma ze-VOC ezifanelekileyo zinokunciphisa ukukhutshwa komoya okunokuphepheka ngokukhawuleza, ziphucule umgangatho weendawo zokusebenza, kwaye zibe yinxalenye yamaphulo okugcina uzinzo ixesha elide.
