Icala Lokusetshenziswa Kwesitshalo Sikagesi Esishisayo eShanghai

I-Shanghai Certain Thermal Power Co., Ltd. isebenza ngaphakathi kobubanzi bebhizinisi obuhlanganisa ukukhiqizwa nokuthengiswa kwamandla okushisa, ukuthuthukiswa kobuchwepheshe bokukhiqiza amandla okushisa, kanye nokusetshenziswa okuphelele komlotha ompukane. Le nkampani okwamanje isebenzisa ama-boiler amathathu asebenzisa igesi yemvelo anomthamo wamathani ayi-130 ngehora kanye namasethi amathathu ejeneretha ye-turbine yomusi ocindezelayo emuva anomthamo ofakiwe ongama-MW angu-33. Ihlinzeka ngomusi ohlanzekile, onobungani nemvelo, kanye nekhwalithi ephezulu kubasebenzisi bezimboni abangaphezu kuka-140 abasezindaweni ezifana ne-Jinshan Industrial Zone, i-Tinglin Industrial Zone, kanye ne-Caojing Chemical Zone. Inethiwekhi yokusabalalisa ukushisa idlula amakhilomitha angaphezu kwama-40, ihlangabezana ngempumelelo nezidingo zokushisa ze-Jinshan Industrial Zone kanye nezindawo zezimboni ezizungezile.

Uhlelo lwamanzi nomusi esiteshini samandla esishisayo luhlanganiswe kuzo zonke izinqubo zokukhiqiza eziningi, okwenza ukuqapha ikhwalithi yamanzi kube yinto ebalulekile ukuqinisekisa ukusebenza okuphephile nokuthembekile kohlelo. Ukuqapha okuphumelelayo kunegalelo ekusebenzeni okuzinzile kohlelo lwamanzi nomusi, kuthuthukisa ukusebenza kahle kwamandla, futhi kunciphisa ukuguguleka kwemishini. Njengethuluzi elibalulekile lokuqapha ku-inthanethi, i-analyzer yekhwalithi yamanzi idlala indima ebalulekile ekutholeni idatha ngesikhathi sangempela. Ngokunikeza impendulo ngesikhathi esifanele, kwenza abaqhubi bakwazi ukulungisa izinqubo zokwelashwa kwamanzi ngokushesha, ngaleyo ndlela bavimbele ukulimala kwemishini kanye nezingozi zokuphepha, futhi baqinisekise ukusebenza okuphumelelayo nokuzinzile kohlelo lokukhiqizwa kwamandla.
Ukuqapha amazinga e-pH: Inani le-pH lamanzi ebhoyila kanye ne-steam condensate kumele ligcinwe ngaphakathi kobubanzi be-alkaline obufanele (ngokuvamile phakathi kuka-9 no-11). Ukuphambuka kulolu bubanzi—kungaba yi-acidic kakhulu noma i-alkaline kakhulu—kungaholela ekugqwaleni kwepayipi lensimbi kanye nebhoyila noma ukwakheka kwesikali, ikakhulukazi lapho kukhona ukungcola. Ngaphezu kwalokho, amazinga e-pH angajwayelekile angase aphazamise ubumsulwa bomusi, okuthi kamuva kuthinte ukusebenza kahle kanye nokuphila kwenkonzo yemishini engezansi njengama-turbine e-steam.

Ukuqapha ukuhanjiswa kwegesi: Ukuhanjiswa kwegesi kusebenza njengesibonakaliso sokuhlanzeka kwamanzi ngokukhombisa ukuhlushwa kukasawoti nama-ion ancibilikisiwe. Ezitshalweni zamandla ezishisayo, amanzi asetshenziswa ezinhlelweni ezifana namanzi okuphakelwa kwegesi kanye ne-condensate kumele ahlangabezane nezindinganiso zokuhlanzeka eziqinile. Amazinga aphezulu okungcola angabangela ukukala, ukugqwala, ukwehla kokusebenza kahle kokushisa, kanye nezehlakalo ezingaba zimbi njengokwehluleka kwamapayipi.

Ukuqapha umoya-mpilo oncibilikisiwe: Ukuqapha okuqhubekayo komoya-mpilo oncibilikisiwe kubalulekile ekuvimbeleni ukugqwala okubangelwa umoya-mpilo. Umoya-mpilo oncibilikisiwe emanzini ungasabela ngamakhemikhali nezingxenye zensimbi, okuhlanganisa amapayipi kanye nezindawo zokushisa zebhoyila, okuholela ekuwohlokeni kwezinto, ukuncipha kodonga, kanye nokuvuza. Ukuze kuncishiswe le ngozi, izitshalo zamandla okushisa zivame ukusebenzisa ama-deaerators, futhi abahlaziyi be-oxygen abancibilikisiwe basetshenziswa ukuqapha inqubo yokuncipha komoya-mpilo ngesikhathi sangempela, ukuqinisekisa ukuthi amazinga omoya-mpilo oncibilikisiwe ahlala ngaphakathi kwemingcele eyamukelekayo (isb., ≤ 7 μg/L emanzini okuhambisa amanzi ebhoyila).

Uhlu Lomkhiqizo:
I-pHG-2081Pro I-Analyzer ye-pH eku-inthanethi
Isihlaziyi Sokuqhuba Oku-inthanethi se-ECG-2080Pro
Isihlaziyi Se-Oxygen Esincibilikisiwe Esiku-inthanethi se-DOG-2082Pro

Lolu cwaningo lugxile kuphrojekthi yokuvuselela i-sampling rack esiteshini esithile samandla okushisa eShanghai. Ngaphambilini, i-sampling rack yayinezinsimbi namamitha avela kumkhiqizo ongenisiwe; noma kunjalo, ukusebenza kwasendaweni kwakungagculisi, futhi ukwesekwa ngemuva kokuthengisa akuzange kuhlangabezane nokulindelwe. Ngenxa yalokho, inkampani yanquma ukuhlola ezinye izindlela zasekhaya. I-Botu Instruments yakhethwa njengomkhiqizo wokufaka esikhundleni futhi yenza ukuhlolwa okuningiliziwe kwasendaweni. Ngenkathi uhlelo lokuqala lwaluhlanganisa ama-electrode angenisiwe, izinkomishi zokugeleza, kanye namakholomu okushintshana kwama-ion, konke okwakwenziwe ngokwezifiso, uhlelo lokulungisa lwaluhilela hhayi nje ukufaka esikhundleni izinsimbi nama-electrode kodwa futhi nokuthuthukisa izinkomishi zokugeleza kanye namakholomu okushintshana kwama-ion.

Ekuqaleni, isiphakamiso sokuklama sasikisela izinguquko ezincane ezinkomishini zokugeleza ngaphandle kokushintsha isakhiwo sendlela yamanzi esikhona. Kodwa-ke, ngesikhathi sokuvakasha okulandelayo kwesiza, kwatholakala ukuthi izinguquko ezinjalo zingase zibe nomthelela ekunembileni kokulinganisa. Ngemva kokubonisana nethimba lobunjiniyela, kwavunyelwana ukuthi kusetshenziswe ngokugcwele uhlelo lokulungisa oluphelele olunconywe yi-BOQU Instruments ukuze kuqedwe noma yiziphi izingozi ezingaba khona emisebenzini yesikhathi esizayo. Ngemizamo yokubambisana ye-BOQU Instruments kanye nethimba lobunjiniyela elisendaweni, iphrojekthi yokulungisa yaqedwa ngempumelelo, okwenza uphawu lwe-BOQU lukwazi ukufaka esikhundleni ngempumelelo imishini esetshenziswe ngaphambilini engenisiwe.

Lo msebenzi wokulungisa uhlukile kumaphrojekthi wangaphambilini wezitshalo zamandla ngenxa yokubambisana kwethu nomkhiqizi wohlaka lwesampula kanye nokulungiselela kusengaphambili okwenziwe. Azikho izinselelo ezibalulekile ezihlobene nokusebenza noma ukunemba kwezinsimbi lapho kufakwa esikhundleni semishini engenisiwe. Inselelo eyinhloko yayikukuguqula uhlelo lwamanzi lwe-electrode. Ukuqaliswa okuphumelelayo kwakudinga ukuqonda okujulile indebe yokugeleza kwe-electrode kanye nokucushwa komzila wamanzi, kanye nokuxhumana okuseduze nosonkontileka wobunjiniyela, ikakhulukazi emisebenzini yokushisela amapayipi. Ngaphezu kwalokho, sithole ithuba lokuncintisana enkonzweni yangemva kokuthengisa, njengoba sinikeze izikhathi eziningi zokuqeqesha kubasebenzi bendawo maqondana nokusebenza kwemishini kanye nokusetshenziswa okufanele.
