Njengoko imigangatho yokukhutshwa kwemizi-mveliso iqina kwihlabathi jikelele, abaqhubi bajongana nombuzo onzima: ubonisa njani ukuba isityalo sakho sihlala sithobela xa imida evunyelweyo iphantse isezantsi ngokungenakubonwa? Impendulo ithi
Ukukhutshwa kwe-ultra-low eqhubekayo yokubeka iliso kwigesi yomkhuhlane -Itekhnoloji ekuvumela ukuba ulinganise izinto ezikhutshwayo ngokuchanekileyo, ngokuqhubekayo, kwaye kufutshane nexesha lokwenyani.
Esi sikhokelo sichaza ukuba yintoni ukukhutshwa kwe-ultra-low eqhubekayo yokubeka iliso kwi-flue gas, kutheni ibalulekile, isebenza njani, kwaye yintoni ekufuneka uyiqwalasele xa uhambisa inkqubo.
Yintoni i-Ultra-Low Emissions eqhubekayo yokuJonga iGesi yeFlue?
Ukukhutshwa kwegesi ephantsi kakhulu okuphantsi kakhulu kubhekiselele kumlinganiselo oqhubekayo wokugxininiswa kongcoliseko kwirhasi yokukhupha evela kwimfumba yemizi-mveliso, iibhoyila, kunye neenkqubo zokutsha, kuluhlu loxinaniso oluphantsi kakhulu olufunwa yimigaqo yale mihla yokusingqongileyo.
Igama elithi "i-ultra-low emissions" lichaza amanqanaba ongcoliseko olungqingqwa - rhoqo kwiindawo ezinedijithi enye kwisigidi (ppm) okanye iinxalenye kwibhiliyoni nganye (ppb) - ekufuneka izityalo kumazwe amaninzi ngoku zihlangane. Ukulinganisa ngokuchanekileyo kwezi ngxiloniso ziphantsi kufuna ngaphezulu komhlalutyi osisiseko; ifuna ukuzinikela inkqubo yokubeka iliso eqhubekayo (CEMS) iyilwe ngovakalelo olwaneleyo, uzinzo, kunye nolungiso oluphambukayo.
Ngokwezinto ezisebenzayo, inkqubo isampula igesi ephumayo kwi-stack, ilinganisa ungcoliseko oluphambili ngokuqhubekayo, irekhoda idatha, kwaye ihlala iyithumela kubalawuli okanye kwigumbi lolawulo lokunika ingxelo yokuthotyelwa.
Kutheni iMiba yokuBeka esweni iMicimbi ephantsi kakhulu
Kukho abaqhubi ababini abaphambili emva kwemfuno ekhulayo yobu buchwepheshe:
- Ukuthotyelwa kwemigaqo. Imimandla emininzi yazise imida engqongqo yokukhupha initrogen oxides (NOx), sulfur dioxide (SO2), particulate matter, kunye necarbon monoxide. Abanini-zithuthi kufuneka babonise ukuthobela ngomlinganiselo othembekileyo, oqhubekayo - hayi iisampulu ezenziwa ngesandla.
- Uxanduva lokusingqongileyo kunye nodumo. Ukubeka iliso okuchanekileyo kuxhasa ulawulo olungcono lokutsha, ukusetyenziswa kwepetroli okuphantsi, kunye nomsebenzi ococekileyo obonakalayo, obalulekileyo kuluntu, abathengi kunye nabatyali-mali ngokufanayo.
Ngaphandle kokuthotyelwa, idatha eqhubekayo yokubeka iliso inceda iinjineli ukuba zikhulise ukusebenza kakuhle kokutsha, zibone iimpazamo kwangethuba, kwaye zinciphise iindleko zokusebenza.
Njani Umsebenzi wokuJonga iGesi yeFlue ngokuNgaphantsi kakhulu?
Isixokelelwano esiqhubekayo sokuhlola irhasi ye-flue yakhiwe kwiindawo ezininzi ezilungelelanisiweyo:
| Icandelo | Indima |
| Inkqubo yesampulu | Ikhupha isampuli yegesi emele kwi-stack kunye nemeko yayo (ukucoca, ukomisa, ukulawula ukushisa). |
| Abahlalutyi begesi | Yenza umlinganiselo wokugxila kungcoliseko usebenzisa imigaqo yomlinganiselo ozinikeleyo. |
| Inkqubo yokufunyanwa kwedatha | Urekhoda ufundo, ubala i-avareji kunye neetotali ezikhutshwayo, kunye nokugcina idatha yokunika ingxelo. |
| Ulungelelwaniso / ukuqinisekiswa | Ukuhlolwa kwe-zero rhoqo kunye ne-span kuqinisekisa ukuba abahlalutyi bahlala bechanekile ngokuhamba kwexesha. |
Iindlela ezimbini zesampulu ezibanzi ziqhelekileyo:
- Ukujongwa kwe-extractive (in-situ okanye dilution). - isampuli ithathwa kwi-stack kwaye ihanjiswe kwi-analyzer yokulinganisa. Oku kusetyenziswa ngokubanzi kwi-ultra-low concentration applications kuba ivumela ukulungiswa ngononophelo kunye nokulinganisa.
- Ukubeka iliso kwi-situ / cross-duct - abahlalutyi balinganisa ngokuthe ngqo ngaphakathi okanye ngapha kwe-stack, ngokufuthi besebenzisa iindlela zamehlo. Oku kunika impendulo ekhawulezayo kunye nokuphathwa kwesampulu encinci.
Ukhetho luxhomekeke kuhlobo lwegesi, uluhlu loxinaniso, iimeko zemfumba, kunye nemeko yokugcinwa kwenkunkuma kwindawo nganye.
Zeziphi Izinto Ezingcolisayo Ezilinganiswayo?
Inkqubo yokujonga izinto ezikhutshwayo ezisezantsi kakhulu ilandelela iiparamitha ezininzi eziphambili:
| Ipharamitha | Kutheni ibekwe esweni |
| NOx (nitrogen oxides) | Ungcoliseko oluphambili olulawulwayo lokutsha kunye nonegalelo kwimvula yomsi neasidi. |
| I-SO2 (i-sulphur dioxide) | Ukukhutshwa kumafutha anesalfure; ilawulwa ngokuqinileyo kumashishini amaninzi. |
| I-CO (carbon monoxide) | Isalathisi sokutsha okungaphelelanga kunye nesiphawuli sokhuseleko kunye nokusebenza kakuhle. |
| I-particle / dust | Amasuntswana aqinileyo kwigesi yombane; ngokuphantsi kwemida engqongqo yoxinaniso lobunzima. |
| O2 (ioksijini) | Isetyenziselwa ukulungisa ufundo kunye nokuvavanya ukusebenza kakuhle kokutsha. |
| CO2 | Iya ihambelana kakhulu ne-greenhouse-gas accounting kunye nohlalutyo olusebenzayo. |
Uluhlu olukhethekileyo lweeparamitha ezilawulwayo ziyohluka ngokwelizwe, uhlobo lwepetroli, kunye necandelo leshishini, ngoko ke iimfuno kufuneka ziqinisekiswe ngokuchasene nommiselo osebenzayo wendawo wofakelo ngalunye.
ITekhnoloji yoMlinganiso yeeNxibelelwano eziPhantsi kakhulu
Ukufikelela kufundo oluthembekileyo kwiindawo eziphantsi kakhulu kufuna abahlalutyi abanovakalelo oluphezulu kunye nokuphazamiseka okuphantsi. Ubuchule obuqhelekileyo bubandakanya:
- I-non-dispersive infrared (NDIR) - isetyenziswa ngokubanzi kwi-CO, CO2, kunye ne-SO2 yokulinganisa.
- I-Chemiluminescence - ubuchule obuqhelekileyo be-NOx kwiindawo eziphantsi.
- I-UV / DOAS (i-spectroscopy eyahluka-hlukileyo yokufunxwa kwamehlo) - esebenzayo kwinqanaba eliphantsi le-NOx, i-SO2, kunye nezinye iigesi ezinamabhendi e-UV absorption.
- I-Laser-based (TDLAS) abahlalutyi -Nika impendulo ekhawulezayo kunye nokuhamba okuncinci, okuya kusetyenziselwa umlinganiselo wokuxinana okuphantsi.
- I-Beta-ray okanye iimitha zothuli lwe-triboelectric - ixhaphakile ekubekeni iliso rhoqo kwimiba ethile.
Itekhnoloji efanelekileyo ixhomekeke kwigesi ekujoliswe kuyo, uluhlu olulindelekileyo loxinaniso, kunye nokuphazamiseka okukhoyo kwi-matrix yegesi ye-flue ethile.
Iingqwalaselo eziPhambili Xa uFaka iNkqubo
Ukufakela i-ultra-low emissions monitoring system kubandakanya okungaphezulu kunokuthenga i-analyzer. Ukufumana idatha ethembekileyo, ekhuselekayo, qaphela:
- Ukutshatisa i-analyzer kuluhlu. I-analyzer enoluhlu olugqithileyo kwi-ultra-low concentrations ayiyi kuzisa ukuchaneka okudingayo.
- Umgangatho wokulungisa isampuli. Kwiindawo eziphantsi, umswakama, ubushushu, kunye nokungcola kwisampulu kunokuphazamisa ukufundwa; inkqubo yesampulu eyilwe kakuhle ibalulekile.
- Ulawulo lokuphambana. Ezinye iigesi ezikhoyo kwi-flue gas zinokuphazamisa ukulinganisa; khetha abahlalutyi ngokulungiswa kokuphazamiseka okuqinisekisiweyo.
- Ulungelelwaniso lwesiqhelo. Ukuhlolwa okuziro kunye nobude bexesha kubalulekile ukugcina ukuchaneka nokuhlangabezana nokulindelweyo kuphicotho.
- Ukuthembeka kwedatha kunye nokunika ingxelo. Inkqubo eyomeleleyo yokufunyanwa kwedatha iqinisekisa ukuba iirekhodi zigqityiwe, zifakwe isitampu sexesha, kwaye zilungele ukuphononongwa komlawuli.
Iingcebiso zoLondolozo lweeNkqubo zokuBeka iliso eziqhubekayo
- Ukulinganisa abahlalutyi kwishedyuli efunwa ngumsebenzi wakho kunye nommiselo.
- Hlola kwaye ucoce iiprobe zesampulu kunye nezihluzo rhoqo.
- Ukubeka iliso kwisampulu yokumisela imeko yokuvala okanye ukujiya.
- Landelela i-analyzer drift kwaye uphendule xa isondela kunyamezelo olwamkelekileyo.

Imibuzo Ebuzwa Rhoqo
Uthini umahluko phakathi kokubeka iliso kwirhasi yeflue kunye neCEMS? Ukujongwa kwerhasi yomkhuhlane sisenzo esiqhelekileyo sokulinganisa ukukhutshwa kwezinto ezikhutshwayo. I-CEMS (inkqubo yokubeka iliso eqhubekayo) yinkqubo edibeneyo, ezenzekelayo - isampuli, abahlalutyi, kunye nokufumana idatha - eyenza lo mlinganiso ngokuqhubekayo ngenjongo yokuthotyelwa.
Kutheni le nto izinto ezikhutshwayo eziphantsi kakhulu kunzima ukuzilinganisa? Kwiindawo ezisezantsi kakhulu, imiqondiso incinci, ke ngoko ubuntununtunu be-analyzer, uzinzo, kunye nokukwazi ukulungisa iigesi eziphazamisayo zibaluleke kakhulu. Isixhobo esisebenza kakuhle kugxininiso oluphezulu sinokungachaneki ngokwaneleyo kumanqanaba asezantsi kakhulu.
Kufuneka kulinganiswe kangaphi inkqubo yokubeka iliso kwirhasi yombane? Ukuphindaphinda kolungelelwaniso kuyahluka ngokommiselo kunye nokusebenza kwendawo. Iisistim ezininzi zisebenza ngokuzenzekela u-zero kunye nokutshekishwa kwe-span yonke imihla kwaye zenze ulungelelwaniso olupheleleyo kwishedyuli yolondolozo echaziweyo. Ngalo lonke ixesha ulandela iimfuno zasekuhlaleni ezifanelekileyo.
Ngaba inkqubo enye inokubek' esweni izingcolisi ezininzi? Ewe. Uninzi lweenkqubo zanamhlanje zidibanisa abahlalutyi abaninzi okanye abahlalutyi begesi eninzi ukulinganisa iiparitha ezininzi (ezifana ne-NOx, i-SO2, i-CO, kunye ne-O2) ukusuka kwisampuli efanayo.
