I-carbon monoxide, ama-nitrogen oxide, ama-organic compounds aguquguqukayo, i-sulfur dioxide, kanye nama-particulate avame ukubizwa ngokuthi “ama-comteria pollution” ngenxa yeqhaza lawo ekwakhiweni kwentuthu yasemadolobheni. Lokhu futhi kunomthelela esimweni sezulu somhlaba wonke, yize umthelela wawo ulinganiselwe ngoba imiphumela yawo yokushiswa ayiqondile, njengoba engasebenzi ngqo njengamagesi okushisa kodwa asabela namanye amakhemikhali amakhemikhali asemkhathini. Ukushiswa kwamafutha emvelo, njenge-coal kanye namafutha aqinile (i-HFO), kukhulula ezintathu zezindawo ezingcolisa umoya, njenge-sulfur dioxide (SO2), i-nitrogen oxides (NOX), kanye nama-particulate. Ama-particulate angasuswa ngendlela eyanelisayo ngama-electrostatic precipitators noma ama-cyclone, kanti ukukhishwa kwama-nitrogen oxides kungancishiswa ngokusebenzisa ama-low NOX burners. Ukukhishwa kwe-sulfur dioxide kungancishiswa ngokususwa kwe-sulfur ku-fuel ngaphambi kokushisa, ngokususwa kwe-sulfur dioxide ngesikhathi senqubo yokushisa, noma ngokususwa kwe-sulfur dioxide kuma-flue gases ngemva kokushisa. Ukulawulwa kwangaphambi kokushisa kuhlanganisa ukukhethwa kwamafutha e-sulfur aphansi kanye nokususwa kwe-fuel desulfurization. Izilawuli zokusha zenzelwe ikakhulukazi izitshalo ezivamile ezisebenzisa amalahle futhi zifaka ama-sorbents okujova esithandweni somlilo. Izilawuli zangemuva kokusha yizinqubo zokususa i-flue gas desulfurization (FGD).
Ama-nozzle e-RBSC (SiSiC) desulphurization ayizingxenye ezibalulekile zesistimu ye-flue gas desulphurization ezitshalweni zamandla ezishisayo kanye nama-boiler amakhulu. Afakwe kabanzi ohlelweni lwe-flue gas desulphurization lwezitshalo eziningi zamandla ezishisayo kanye nama-boiler amakhulu. Ezimbonini zekhulu lama-21 emhlabeni wonke zizobhekana nezidingo ezikhulayo zokusebenza okuhlanzekile nokusebenza kahle.
Inkampani i-ZPC (www.rbsic-sisic.com) izibophezele ekwenzeni ingxenye yethu yokuvikela imvelo. I-ZPC facory igxile ekwakhiweni kwe-spray nozzle kanye nokusungula izinto ezintsha kwezobuchwepheshe embonini yokulawula ukungcola. Ngokusebenza kahle kakhulu kwe-spray nozzle kanye nokuthembeka, ukukhishwa okunobuthi okuphansi emoyeni nasemanzini ethu manje sekufezwa. Imiklamo ye-BETE ye-nozzle ephakeme ifaka ukuvalwa kwe-nozzle okuncishisiwe, ukusatshalaliswa kwephethini yokufafaza okuthuthukisiwe, impilo ye-nozzle ende, kanye nokuthembeka nokusebenza kahle okwandisiwe. Le nozzle esebenza kahle kakhulu ikhiqiza ububanzi obuncane kakhulu be-droplet ngengcindezi ephansi okuholela ekunciphiseni izidingo zamandla zokupompa.
Inkampani i-ZPC ine: Umugqa obanzi kakhulu wama-nozzle ajikelezayo okuhlanganisa imiklamo ethuthukisiwe engavimbeli ukuvaleka, ama-engeli abanzi, kanye nohlu oluphelele lokugeleza. Uhlu oluphelele lwemiklamo ejwayelekile yama-nozzle: i-tangential inlet, ama-nozzle e-whirl disk, kanye nama-nozzle abalandeli, kanye nama-nozzle akhipha umoya aphansi naphezulu okusebenzisa izinhlelo zokucima nokuhlanza okomile. Ikhono elingenakuqhathaniswa lokuklama, ukukhiqiza nokuletha ama-nozzle enziwe ngokwezifiso. Sisebenzisana nawe ukuze sihlangabezane nemithetho kahulumeni eqinile. Singahlangabezana nezidingo zakho ezikhethekile, sikusize ukuthi ufinyelele ukusebenza kahle kwesistimu.
Izinhlobo ze-nozzle – Ububanzi obufanele kanye nokuhlakazeka kwamaconsi
I-ZPC ikhulisa ukusebenza kahle kokumuncwa kwe-SO2 ngomklamo ofanele kanye nendawo ebhange lokufafaza lama-nozzle okufafaza. I-cone yethu engenalutho kanye nama-nozzle aqondiswe kabili abekwe ngemodeli yekhompyutha ukuze kufezwe ukuxhumana okuhle kwegesi noketshezi, ukusebenza kahle kokuhlafuna nokunciphisa ukucwila kwegesi.
Incazelo emfushane yezindawo ze-FGD Scrubber
Cima:
Kulesi sigaba se-scrubber, amagesi ashisayo ancishisiwe izinga lokushisa ngaphambi kokungena kwi-pre-scrubber noma i-absorber. Lokhu kuzovikela noma yiziphi izingxenye ezizwela ukushisa kwi-absorber futhi kunciphise umthamo wegesi, ngaleyo ndlela kwandiswe isikhathi sokuhlala kwi-absorber.
I-Pre-Scrubber:
Lesi sigaba sisetshenziselwa ukususa izinhlayiya, ama-chloride, noma kokubili kugesi yoketshezi.
Isifunxi:
Lokhu ngokuvamile kuyinqaba yokufutha evulekile eletha i-slurry ye-scrubber ukuthi ihlangane negesi yomoya ongcolile, okuvumela ukusabela kwamakhemikhali okubopha i-SO2 ukuthi kwenzeke e-sump.
ukupakisha:
Eminye imibhoshongo inesigaba sokupakisha. Kulesi sigaba, i-slurry isakazwa ekupakisheni okuxekethile noma okuhlelekile ukuze kwandiswe indawo ethintana negesi yomoya ongcolile.
Ithreyi Yebhamuza:
Eminye imibhoshongo inepuleti elinezimbobo ngaphezu kwesigaba sokumunca. I-slurry ibekwa ngokulinganayo kuleli puleti, okulinganisa ukugeleza kwegesi futhi kuhlinzeke indawo engaphezulu ethintana negesi.
Umqedi Wezinkungu:
Zonke izinhlelo ze-FGD ezimanzi zikhiqiza iphesenti elithile lamaconsi amancane kakhulu athwalwa ukuhamba kwegesi yomoya ophumayo eya endaweni yokuphuma yombhoshongo. I-mist eliminator iwuchungechunge lwama-vane ahlanganisiwe abamba futhi ahlanganise amaconsi, avumela ukuthi abuyiselwe ohlelweni. Ukuze kugcinwe ukusebenza kahle kokususa amaconsi aphezulu, ama-vane e-mist eliminator kumele ahlanzwe njalo.
