Icala Lokusetshenziswa Kwesitshalo Sikagesi Esizimele Embonini Yephepha Ethile eFujian

Inkampani ethile yesibopho esilinganiselwe embonini yephepha etholakala eSifundazweni saseFujian ingenye yamabhizinisi amakhulu okukhiqiza iphepha esifundazweni futhi iyinkampani ebalulekile yesifundazwe ehlanganisa ukwenziwa kwephepha okukhulu nokukhiqizwa kokushisa namandla okuhlangene. Isikali sokwakha esiphelele sale phrojekthi sihlanganisa amasethi amane “ama-boiler ombhede agcwele uketshezi angu-630 t/h asebenza ngokushisa okuphezulu kanye nokucindezela okuphezulu kwamafutha amaningi + ama-turbine omusi we-back-pressure angu-80 MW + amajeneretha angu-80 MW,” kanye nebhoyili eyodwa esebenza njengeyunithi yokusekela. Le phrojekthi iqaliswa ngezigaba ezimbili: isigaba sokuqala siqukethe amasethi amathathu okucushwa kwemishini okukhulunywe ngayo ngenhla, kanti isigaba sesibili sengeza isethi eyodwa eyengeziwe.

Ukuhlaziywa kwekhwalithi yamanzi kudlala indima ebalulekile ekuhlolweni kwebhoyila, njengoba ikhwalithi yamanzi ithinta ngqo ukusebenza kwebhoyila. Ikhwalithi yamanzi engeyinhle ingaholela ekungasebenzi kahle kokusebenza, ekulimaleni kwemishini, kanye nezingozi zokuphepha ezingaba khona kubasebenzi. Ukusetshenziswa kwezinsimbi zokuqapha ikhwalithi yamanzi eziku-inthanethi kunciphisa kakhulu ingozi yezehlakalo zokuphepha ezihlobene nebhoyila, ngaleyo ndlela kuqinisekiswe ukusebenza okuphephile nokuzinzile kohlelo lwebhoyila.

Le nkampani isebenzise amathuluzi okuhlaziya ikhwalithi yamanzi kanye nezinzwa zokufanisa ezikhiqizwe yi-BI-OQUNgokuqapha amapharamitha anjenge-pH, ukuhanjiswa kwamandla kagesi, i-oxygen encibilikisiwe, i-silicate, i-phosphate, kanye nama-ion e-sodium, kuqinisekisa ukusebenza okuphephile nokuzinzile kwebhoyila, kwandise impilo yesevisi yemishini, futhi kuqinisekisa ikhwalithi yomusi.

Imikhiqizo Esetshenzisiwe:
I-pHG-2081Pro I-Analyzer ye-pH eku-inthanethi
I-DDG-2080Pro Online Conductivity Analyzer
INJA-2I-082Pro Online Dissolved Oxygen Analyser
I-GSGG-5089Pro I-Silicate Analyzer eku-inthanethi
I-LSGG-5090Pro Online Phosphate Analyzer
I-DWG-5088Pro I-Sodium Ion Analyzer eku-inthanethi

Inani le-pH: I-pH yamanzi ebhoyila idinga ukugcinwa ngaphakathi kobubanzi obuthile (ngokuvamile 9-11). Uma iphansi kakhulu (ine-asidi), izogqwala izingxenye zensimbi zebhoyila (njengemibhobho yensimbi kanye nezigubhu zomusi). Uma iphakeme kakhulu (ine-alkaline kakhulu), ingabangela ukuthi ifilimu evikelayo ebusweni bensimbi iwe, okuholela ekugqwaleni kwe-alkaline. I-pH efanele ingavimbela nomphumela wokugqwala kwe-carbon dioxide yamahhala emanzini futhi inciphise ingozi yokukhuphuka kwamapayipi.

Ukuqhuba: Ukuqhuba kubonisa okuqukethwe okuphelele kwama-ion ancibilikisiwe emanzini. Uma inani liphakeme, kulapho ukungcola okuningi (njengosawoti) kuba khona emanzini. Ukuqhuba okuphezulu kakhulu kungaholela ekukhuleni kwebhoyila, ukugqwala okusheshayo, futhi kungathinta nekhwalithi yomusi (njengokuthwala usawoti), kunciphise ukusebenza kahle kokushisa, futhi kubangele ngisho nezehlakalo zokuphepha njengokuqhuma kwamapayipi.

I-oxygen encibilikisiwe: I-oxygen encibilikisiwe emanzini iyimbangela eyinhloko yokugqwala kwe-oxygen kwezinsimbi ze-boiler, ikakhulukazi kuma-economizer kanye nezindonga ezipholiswe ngamanzi. Kungaholela ekuqhekekeni nasekuncipheni kobuso bensimbi, futhi ezimweni ezimbi kakhulu, ukuvuza kwemishini. Kuyadingeka ukulawula i-oxygen encibilikisiwe ezingeni eliphansi kakhulu (ngokuvamile ≤ 0.05 mg/L) ngokwelashwa kokuncipha komoya (njengokuncipha komoya oshisayo kanye nokuncipha kwamakhemikhali).

I-Silicate: I-Silicate ithambekele ekuguquguqukeni komoya ngenxa yomusi ngaphansi kokushisa okuphezulu kanye nengcindezi, ifakwa ezinsikeni ze-turbine ukuze yakhe isikali se-silicate, okunciphisa ukusebenza kahle kwe-turbine futhi kuthinte nokusebenza kwayo okuphephile. Ukuqapha i-silicate kungalawula okuqukethwe kwe-silicate emanzini e-boiler, kuqinisekise ikhwalithi yomusi, futhi kuvimbele ukukhushulwa kwe-turbine.

Impande ye-phosphate: Ukwengeza usawoti we-phosphate (njenge-trisodium phosphate) emanzini abilayo kungasabela nama-ion e-calcium ne-magnesium ukwakha ama-phosphate precipitates athambile, kuvimbele ukwakheka kwe-hard scale (okungukuthi, "ukwelashwa kokuvimbela i-phosphate scale"). Ukuqapha ukuhlushwa kwempande ye-phosphate kuqinisekisa ukuthi ihlala ngaphakathi kwebanga elifanele (ngokuvamile 5-15 mg/L). Amazinga aphezulu kakhulu angaholela ekutheni izimpande ze-phosphate zithwalwe umusi, kanti amazinga aphansi kakhulu azohluleka ukuvimbela ngempumelelo ukwakheka kwe-scale.

Ama-ion e-Sodium: Ama-ion e-Sodium angama-ion avamile ahlukaniswe usawoti emanzini, futhi okuqukethwe kwawo kungabonisa ngokungaqondile izinga lokuhlushwa kwamanzi e-boiler kanye nesimo sikasawoti esithwalwa umusi. Uma ukuhlushwa kwama-ion e-sodium kuphezulu kakhulu, kubonisa ukuthi amanzi e-boiler agxile kakhulu, okuyinto evame ukubangela ukukhuhla nokugqwala; ama-ion e-sodium amaningi umusi azophinde aholele ekuqongeleleni usawoti ku-turbine yesimusi, okuthinta ukusebenza kwemishini.
