Ikesi Lokusebenza Lesikhungo Samandla Ashisayo e-Shanghai

I-Shanghai Certain Thermal Power Co., Ltd. isebenza ngaphakathi kwendawo yebhizinisi ehlanganisa ukukhiqizwa nokudayiswa kwamandla ashisayo, ukuthuthukiswa kobuchwepheshe bokukhiqiza amandla ashisayo, kanye nokusetshenziswa okuphelele komlotha wezimpukane. Njengamanje le nkampani isebenzisa amabhoyela amathathu emvelo asebenza ngegesi enamandla angu-130 amathani ngehora kanye namasethi amathathu ajeneretha enjini yokucindezela anamandla angu-33 MW. Ihlinzeka ngesitimu esihlanzekile, esinobungani nemvelo, kanye nekhwalithi ephezulu kubasebenzisi bezimboni abangaphezu kuka-140 abasezindaweni ezifana ne-Jinshan Industrial Zone, i-Tinglin Industrial Zone, ne-Caojing Chemical Zone. Inethiwekhi yokusabalalisa ukushisa ihamba ngaphezu kwamakhilomitha angu-40, ihlangabezana ngempumelelo nezidingo zokushisisa ze-Jinshan Industrial Zone kanye nezindawo zezimboni ezizungezile.

Uhlelo lwamanzi nesitimu endaweni yokuphehla amandla ashisayo ludidiyelwe ezinqubweni eziningi zokukhiqiza, okwenza ukuqapha ikhwalithi yamanzi kubaluleke kakhulu ukuze kuqinisekiswe ukusebenza kwesistimu okuphephile nokuthembekile. Ukuqapha okuphumelelayo kunomthelela ekusebenzeni okuzinzile kwesistimu yamanzi nesitimu, kuthuthukisa ukusebenza kahle kwamandla, futhi kunciphisa ukuguga kwemishini. Njengethuluzi elibalulekile lokuqapha ku-inthanethi, isihlaziyi sekhwalithi yamanzi sidlala indima ebalulekile ekutholweni kwedatha ngesikhathi sangempela. Ngokunikeza impendulo ngesikhathi, kwenza abaqhubi bakwazi ukulungisa izinqubo zokuhlanza amanzi ngokushesha, ngaleyo ndlela kuvimbele ukulimala kwemishini kanye nobungozi bokuphepha, kanye nokuqinisekisa ukusebenza kahle nokuzinzile kohlelo lokuphehla ugesi.
Ukuqapha amazinga e-pH: Inani le-pH lamanzi okubhayela kanye ne-steam condensate kufanele igcinwe ngaphakathi kwebanga elifanele le-alkaline (ngokuvamile eliphakathi kuka-9 no-11). Ukuchezuka kusuka kulobu bubanzi—okune-asidi kakhulu noma i-alkaline ngokweqile—kungaholela epayipini lensimbi nokugqwala kwebhayela noma ukwakheka kwesikali, ikakhulukazi uma kukhona ukungcola. Ukwengeza, amazinga e-pH angavamile angase abeke engcupheni ukuhlanzeka kwesitimu, okubuye kuthinte ukusebenza kahle nempilo yesevisi yemishini ephansi yomfula njengama-turbines.

I-Monitoring conductivity: I-Conductivity isebenza njengenkomba yokuhlanzeka kwamanzi ngokubonisa ukugcwala kosawoti nama-ion ancibilikile. Ezitshalweni zamandla ashisayo, amanzi asetshenziswa ezinhlelweni ezifana namanzi okuphakelayo kubhayela kanye ne-condensate kufanele ahlangabezane nezindinganiso eziqinile zokuhlanzeka. Amazinga aphakeme okungcola angaholela ekukhulisweni, ukugqwala, ukunciphisa ukusebenza kahle kokushisa, kanye nezigameko ezingase zibe zimbi kakhulu njengokungasebenzi kwamapayipi.

Ukuqapha i-oxygen encibilikile: Ukuqapha okuqhubekayo komoya-mpilo oncibilikile kubalulekile ekuvimbeleni ukugqwala okubangelwa umoya-mpilo. I-oxygen encibilikisiwe emanzini ingasabela ngokwekhemikhali nezingxenye zensimbi, okuhlanganisa amapayipi nezindawo zokushisisa ubhayela, okuholela ekonakaleni kwempahla, ukucekelwa phansi kodonga, nokuvuza. Ukuze kuncishiswe le ngozi, izitshalo zamandla ashisayo ngokuvamile zisebenzisa ama-deaerator, futhi izihlaziyi komoya-mpilo ezincibilikisiwe zisetshenziselwa ukuqapha inqubo ye-deaeration ngesikhathi sangempela, ukuqinisekisa ukuthi amazinga omoya-mpilo ancibilikisiwe ahlala ngaphakathi kwemikhawulo eyamukelekayo (isb, ≤ 7 μg/L emanzini okuphakelayo okubhayela).

Uhlu Lomkhiqizo:

Lolu cwaningo lwesibonelo lugxile kuphrojekthi yokulungiswa kwamasampula embonini yamandla ashisayo e-Shanghai. Ngaphambilini, irekhi yamasampula yayifakwe amathuluzi namamitha avela kumkhiqizo ongenisiwe; Nokho, ukusebenza endaweni kwakunganelisi, futhi ukusekelwa ngemva kokuthengisa akuzange kuhlangabezane nalokho okwakulindelwe. Ngenxa yalokho, inkampani yanquma ukuhlola ezinye izindlela zasekhaya. I-Botu Instruments yakhethwa njengophawu olushintshayo futhi yenza ukuhlola okunemininingwane esizeni. Nakuba isistimu yasekuqaleni yayihlanganisa ama-electrode angenisiwe, izinkomishi zokugeleza, namakholomu okushintshanisa i-ion, konke okwakwenziwe ngokwezifiso, uhlelo lokulungisa aluhileli nje ukufaka esikhundleni sezinsimbi nama-electrode kodwa futhi nokuthuthukisa izinkomishi zokugeleza namakholomu okushintshanisa ion.

Ekuqaleni, isiphakamiso sokuklama saphakamisa ukuguqulwa okuncane ezinkomishini zokugeleza ngaphandle kokuguqula isakhiwo esikhona somzila wamanzi. Kodwa-ke, phakathi nokuvakasha kwesayithi okwalandela, kwanqunywa ukuthi ukuguqulwa okunjalo kungase kubeke engcupheni ukunemba kokulinganisa. Ngemva kokubonisana nethimba lonjiniyela, kwavunyelwana ngokuthi kusetshenziswe ngokugcwele uhlelo olubanzi lokulungisa olunconyiwe lwe-BOQU Instruments ukuze kuqedwe noma yiziphi izingozi ezingaba khona ekusebenzeni okuzayo. Ngemizamo yokubambisana ye-BOQU Instruments kanye nethimba lonjiniyela elisendaweni, iphrojekthi yokulungisa yaqedwa ngempumelelo, okwenza uphawu lwe-BOQU lwakwazi ukuthatha indawo ngempumelelo yemishini eyayisetshenziswa ngaphambilini.

Le phrojekthi yokulungisa ihlukile kumaphrojekthi wangaphambilini wesikhungo sikagesi ngenxa yokusebenzisana kwethu nomkhiqizi wohlaka lwamasampula kanye namalungiselelo asenziwe kusengaphambili. Azikho izinselele ezibalulekile ezihlobene nokusebenza noma ukunemba kwamathuluzi lapho kushintshwa okokusebenza ezingenisiwe. Inselele enkulu yayikukulungisa uhlelo lomzila wamanzi we-electrode. Ukuqaliswa ngempumelelo kwakudinga ukuqonda okuphelele kwenkomishi ye-electrode flow cup kanye nokulungiswa komzila wamanzi, kanye nokuxhumana okuseduze nosonkontileka wobunjiniyela, ikakhulukazi imisebenzi yokushisela amapayipi. Ukwengeza, sibe nenzuzo yokuncintisana kusevisi yangemva kokuthengisa, sinikeze izikhathi zokuqeqesha eziningi kubasebenzi abasendaweni mayelana nokusebenza kwemishini nokusetshenziswa okufanele.
