Ngokuqhubela phambili kweshishini kunye nokufudukela ezidolophini, ulawulo lwe-volatile organic compounds (VOCs) aluzange lube lukhulu kakhulu. Ii-VOC zizonke ezisuka kwiifektri, amaziko epetrochemical, amaziko epeyinti, kunye nabashicileli abayingozi nje kwimpilo yabantu kodwa nakwindalo esingqongileyo. Imizi-mveliso ke ngoko yamkela ngokufanelekileyoIinkqubo zokucoca i-VOCnjengenkqubo ebalulekileyo ekususeni izingcolisi zomoya ezingcolileyo kunye nongenelelo lolawulo ekupheliseni umcimbi onjalo.

Ukufunda malunga nee-VOCs kunye neempembelelo zazo

Ii-VOC zizinto eziphilayo eziguquguqukayo ezinoxinzelelo oluphezulu lomphunga kwiqondo lobushushu eliqhelekileyo legumbi kwaye ngenxa yoko ziphuma lula emoyeni. Eminye yeyona mizekelo idumileyo yee-VOCs ibandakanya iingubo, izinto zokuncamathelisa, izinyibilikisi, kunye namafutha. Ukuvezwa ixesha elide kwii-VOC kunokubangela ukugula kokuphefumla, intloko ebuhlungu, kunye neziphumo zexesha elide ezinjengomonakalo wesibindi kunye nezintso. Ngaphandle koku, ii-VOCs zikwavelisa i-ozone ekumgangatho ophantsi kunye nomsi kwaye oko kukhokelela ekuthotyweni kwendalo.

Ezi mpembelelo kufuneka zithotywe zizisombululo ezifanelekileyo zerhasi yenkunkuma ye-VOC kumashishini, ukuze izinto ezikhutshwayo ziphathwe ngokufanelekileyo kwindawo yokuvelisa ukucutha iinyawo zazo kokusingqongileyo.

Iinkqubo zokuCoca i-VOC: Isishwankathelo seTekhnoloji

Iinkqubo ezahlukeneyo zokucoca i-VOC zinokunyanga iintlobo ezahlukeneyo ze-VOC kunye namanqanaba oxinzelelo lwegesi. Iisistim ngokubanzi ziya kubandakanya obu buchwepheshe bulandelayo:

1. I-Thermal Oxidizers

Ezi nkqubo zitshisa ii-VOCs kumaqondo obushushu aphezulu, ziwaqhawule zibe ngumphunga wamanzi ongenabungozi kunye necarbon dioxide. I-oxidizers ye-Thermal isetyenziswe ngokufanelekileyo kwi-VOC ekhutshwayo ephezulu kwaye iyaziwa ngokuthembeka kwayo kunye nokusebenza kakuhle.

2. Catalytic Oxidizers

Ngokuthatha inzuzo yokusetyenziswa kwe-catalyst ukukhuthaza i-oxidation kumaqondo aphantsi aphantsi, i-catalytic oxidizers ziyilo ezisebenza ngamandla ngokumalunga neenkqubo ze-thermal. Zifaneleke kakuhle kwizicelo ezibandakanya amanqanaba asezantsi oxinzelelo lwee-VOCs.

3. IiNkqubo zeCarbon Adsorption ezisebenzayo

Izihluzi zekhabhoni ezisebenzayo zisetyenziswa rhoqo kwiIzicoci zegesi yenkunkuma ye-VOC, ngakumbi kwizinto ezikhutshwayo ezikwiqondo eliphantsi. Ikhabhoni esebenzayo iyasebenza ekubhengezeni iimolekyuli zeVOC ngenxa yobume bayo obunoburharha kwaye yindleko ephantsi kakhulu, enye indlela yogcino oluphantsi.

4. IiYunithi zokuNinga kunye nokufunxa

Ezi yunithi zisusa ii-VOC kwimijelo yegesi ngokusebenzisa ukuhluka kweqondo lokushisa okanye izinyibilikisi zeekhemikhali. Zisetyenziswa rhoqo ngokudityaniswa nobunye ubuchwephesha bokucoca ukukhulisa itekhnoloji.

Iindlela ezahlukeneyo zokucoca ziyafumaneka, nganye ineengenelo ezikhethekileyo ezisekelwe kushishino, ipateni yokukhutshwa, kunye nemimiselo.

Ukukhetha i-VOC eyiNkunkuma yeGesi yoMcoci

Ukukhetha i-VOC efanelekileyo yokucoca igesi yenkunkuma kubalulekile ekusebenzeni ngokufanelekileyo kunye nokuthotyelwa kokusingqongileyo. Oku kulandelayo yingqwalasela:

1. Uhlobo kunye nogxininiso lwe-VOC

I-oxidation ye-thermal ingasetyenziselwa ukukhutshwa koxinzelelo oluphezulu, kunye neenkqubo ze-adsorption zoxinzelelo oluphantsi.

2. Umthamo womoya

Izicelo zemizi-mveliso zifuna izixhobo ezinobunzima obuphezulu.

3. Ukusebenza kakuhle kwamandla

Ukusetyenziswa kwamandla yindleko ebalulekileyo yokusebenza; ngoko, iiyunithi zokubuyisela ubushushu okanye iiyunithi ezincediswa yi-catalyst ziya kunciphisa iindleko zokusebenza.

4. Ukugcinwa kunye neendleko zokusebenza

Ubuncinci beendawo ezihambayo kunye neeyunithi zokuzicoca zinokucutha ixesha lokuphumla kunye neendleko zokuzigcina.

Ngokuphononongwa ngononophelo kwezi khrayitheriya, iimfuno zoncedo zinokudityaniswa nazoIzisombululo zegesi yenkunkuma ye-VOC.

Ukudityaniswa kwiiSmart Monitoring Systems

Kwaye omnye umkhwa ovelayo kulawulo lokukhutshwa kwe-VOC kushishino kukudibanisa iinkqubo zokucoca i-VOC kunye netekhnoloji yokuhlola ekrelekrele. Ezi nkqubo zibandakanya abenzi boluvo kunye nokucubungula ukujonga ngokuqhubekayo ukukhutshwa ngexesha langempela, ukulungelelanisa ngokuzenzekelayo iiparamitha zokusebenza, kunye nokuhambisa ukusebenza ngokucokisekileyo. Oku akukhuphi nje ukusebenza kakuhle kodwa kukwabonelela ngamaxwebhu ophicotho lwemo engqongileyo kunye nokuthotyelwa kwemithetho.

Ukuthotyelwa kweeMfuno zoLawulo kunye neeThagethi zokuZinzisa kwiShishini

Imigaqo kwihlabathi jikelele, kumxholo wezizwe ezifana ne-US Environmental Protection Agency (EPA), i-European Union, kunye noorhulumente bamazwe aseAsia, iya isiba yimithetho engqongqo yokukhupha iVOC. Ukungahambelani nako kutsala izohlwayo eziqatha kunye nomonakalo wegama. Utyalo-mali kwizicoci zegesi yenkunkuma ye-VOC zokwenyani azikhuseli iinkampani kuphela kuxanduva kodwa zikwanceda ekuxhaseni amalinge ozinzo lweshishini.

Ngaphezu koko, uninzi lweenkampani zisebenzisa iindlela zolawulo lwe-VOC njengesicwangciso sokuthengisa kunye nokubonisa. Ukuze baxhalabele umoya ococekileyo, ukuphila okunempilo, kunye neenkqubo zokuvelisa ezihambelana nokusingqongileyo.

Ukuqukumbela

Kwilizwe lemveliso elandayo eco-friendly, izicoci zegesi yenkunkuma ye-VOC ayiseyonto yokuzonwabisa, kodwa iyafuneka. Xa imveliso ifunwa ngokuluhlaza, iinkqubo ezifanelekileyo zerhasi yenkunkuma yeVOC yindlela ekufuneka ithathwe. Ngokusetyenziswa kwe-oxidizers ezishisayo, iinkqubo ze-catalytic, okanye iinkqubo ze-adsorption, i-VOC efanelekileyo yokucoca igesi yenkunkuma inokunciphisa ukukhutshwa okuphephekayo ngokukhawuleza, ukuphucula umgangatho weendawo zokusebenza, kwaye ibe yinxalenye yamaphulo okuzinza kwexesha elide.
