Iyunithi yokususa ama-hydrocarbon anzima egesi yemvelo kanye neyunithi yokususa i-mercury yimishini emibili evamile ku ukucutshungulwa kwegesi yemvelo.
Iyunithi yokususa igesi esindayo yokuhambisa i-hydrocarbon
1（Umsebenzi wesistimu
Ama-hydrocarbon asindayo kanye nama-hydrocarbon anuka kamnandi kugesi yemvelo nawo azoqina emazingeni okushisa aphansi, ngakho-ke kumele asuswe. Le yunithi isebenzisa indlela yokumunca i-carbon esebenzayo ukuze isuse ama-hydrocarbon asindayo kanye nama-hydrocarbon anuka kamnandi.
Kule yunithi, kusetshenziswa imibhoshongo emibili efanayo yokumunca ama-hydrocarbon asindayo nama-hydrocarbon anuka kamnandi. Indlela ye-TSA isetshenziselwa ukuhlaziya ama-hydrocarbon asindayo nama-hydrocarbon anuka kamnandi ku-activated carbon. Ngesikhathi esifanayo, indlela yokumunca isetshenziswa ukuhlanganisa nokuhlukanisa ama-hydrocarbon asindayo nama-hydrocarbon anuka kamnandi akhishwe ku-adsorbent.
2） Amapharamitha okuklama
Umthamo wokucubungula igesi yokuphakelayo: 5 mmscfd
Ingcindezi yokumuncwa kwe-Adsorption 4.4MPa.G
Iphuzu lokuklama le-hydrocarbon esindayo kugesi yokuphakelayo ≤ 1000ppmv
Izinga lokushisa lokumunca ~ 40 ℃
Ingcindezi yokuvuselela kabusha engu-4.2MPa.G
Izinga lokushisa lokuvuselela kabusha 180 ~ 280 ℃
Uwoyela wokudlulisa ukushisa ovuselelayo womthombo wokushisa ophakeme
Okuqukethwe kwe-hydrocarbon esindayo kanye ne-aromatic hydrocarbon kugesi ehlanziwe kufanele kube ngu-≤ 10ppm ngokulandelana
3） Ububanzi bokuzivumelanisa nezimo
Ububanzi bokulawulwa komthwalo buyi-50 ~ 110%.
4） Incazelo yokugeleza kwenqubo
Igesi yemvelo evela ku- iyunithi yokomisa igesi yokondla kuqala ingena isuka phezulu kombhoshongo wokususa ama-hydrocarbon asindayo nge-valve yokulawula ingcindezi ehlukile. Ngemva kokususa i-hydrocarbon esindayo ngokumuncwa kombhede wekhabhoni osebenzayo, iphuma phansi kombhoshongo wokususa ama-hydrocarbon asindayo. Ngemva kokususa i-hydrocarbon esindayo, okuqukethwe yi-aromatic hydrocarbon kugesi yemvelo kungu-≤ 10ppmv, bese ingena kuyunithi yokususa i-mercury kanye nokuhlunga uthuli.
Iyunithi yokususa ama-hydrocarbon anzima ifakwe imibhoshongo emibili yokususa ama-hydrocarbon anzima. Ngaphakathi komjikelezo othile wokususa, eyodwa isesimweni sokususa ama-hydrocarbon anzima kugesi yokudla, kanti eyesibili isesimweni sokuvuselela (ukushisa nokufutha okubandayo) ukuze isuse ama-hydrocarbon anuka kamnandi ku-activated carbon. Lapho umbhoshongo wokususa ama-hydrocarbon anzima esimweni sokususa usugcwele, shintshela embhoshongweni wokususa ama-hydrocarbon anzima oqeda ukuvuselelwa. Umbhoshongo wokususa ama-hydrocarbon anzima usugcwele ulandelwa umjikelezo wokuvuselela ukufudumala bese uphola.
Igesi yokuvuselela itholakala ngaphambili kwevalvu yokulawula ingcindezi ehlukile. Igesi yokuvuselela ingena esithandweni sokushisa segesi yokuvuselela futhi ishiswa ku-220 ~ 280 ℃. Igesi eshisayo neyomile ikhipha ama-hydrocarbon anuka kamnandi ku-activated carbon kusukela phezulu kuya phansi ngombhoshongo wokususa ama-hydrocarbon asindayo. Igesi yokuvuselela equkethe ama-hydrocarbon anuka kamnandi kusuka embhoshongweni wokususa ama-hydrocarbon asindayo esimweni sokuvuselela (ukushisa) ingena esiqandisini segesi yokuvuselela ukuze iphole njalo, bese ihlukanisa ama-hydrocarbon anuka kamnandi angaba khona ku-separator, bese uketshezi oluhlanganisiwe lungena ku-separator yegesi kaphethiloli.
Igesi evela phezulu kwesihlukanisi segesi sokuvuselela ingena embhoshongweni wokumunca esimweni sokumunca kanye negesi yemvelo ephakelayo ngemuva kwevalvu yokulawula ingcindezi ehlukile.
Igesi yokuphakelayoiyunithi yokususa i-mercury kanye nokuhlunga
1） Incazelo yenqubo
Igesi yemvelo evela kuyunithi yokomisa igesi yokudla kanye nokususwa kwe-hydrocarbon esindayo ingena ku-sulfur impregnated activated carbon adsorber. I-Mercury isabela ne-sulfur ku-sulfur impregnated activated carbon ukuze ikhiqize i-mercury sulfide, efakwe ku-activated carbon, ukuze kufezwe injongo yokususwa kwe-mercury. Okuqukethwe kwe-mercury kwegesi yemvelo evela ku-mercury remover kungaphansi kuka-0.01μg/Nm3。
Kusethwa i-mercury remover eyodwa, bese kuthi i-activated carbon efakwe i-sulfur ithathelwe indawo ngokuya ngokutholakala.
Iyunithi yokuhlunga ifakwe isihlungi, esingashintshwa ngokwedatha yokumelana ukuze kufezwe injongo yokuhlunga isihlungi sama-molecule kanye nothuli lwe-carbon olusebenzayo.
Ngemva kokususwa kothuli, izinhlayiya zothuli kugesi yokuphakelayo zingaphansi kuka-10μm.
Imishini eyinhloko i-mercury remover kanye ne-dust filter.
