Gxininisa ku-LIKE—— Guodian Changyuan Jingmen 2 × 640mw 640mw yenkqubo yamanzi yekhemikhali yokwandisa umthamo kunye neprojekthi yokwakhiwa kwakhona

Ngenxa yokuba ezinye izixhobo ze-thermal kwiplanti yamandla zinokuchatshazelwa zizinto ezithile emanzini, okukhokelela kumalungu anobungozi kunye nokubola kwezixhobo, ukusebenza ngokukhuselekileyo kwendawo yombane kuhambelana ngqo nenkqubo yokucoca amanzi ngemichiza. Umonakalo wokungcola emanzini kwisixhobo umisela ukuba amanzi akwiplanti yombane kufuneka acocwe phambi kokuba asetyenziswe. Olu nyango yinkqubo yokucoca amanzi ngemichiza kwindawo yombane. Ubume bophuhliso lwetekhnoloji yokucocwa kwamanzi ngemichiza kwiplanti yombane Kukho iindlela ezintathu eziphambili zokuba umzi-mveliso wombane ufumane amanzi asulungekileyo adityanisiweyo: (1) Ukucaciswa kwendabuko, ukuhluzwa + indlela yokutshintshiselana nge-ion yamkelwe, kwaye inkqubo imi ngolu hlobo lulandelayo: Amanzi akrwada → Isicacisi seflocculation → isihluzi semidiya eninzi → isihluzo sekhabhoni esisebenzayo → ibhedi yokutshintshiselana ngekharbon diokside (2) Umva i-osmosis + indlela yokuvelisa amanzi ebhedi exutyiweyo yamkelwe, kwaye inkqubo imi ngolu hlobo lulandelayo: Amanzi akrwada → isicacisi se-flocculation → isihluzi semithombo yeendaba ezininzi → isihluzo sekhabhoni esisebenzayo → isihluzo esichanekileyo → isihluzo sokhuseleko → impompo yoxinzelelo oluphezulu → umva isixhobo se-osmosis → itanki yamanzi ephakathi → isixhobo sebhedi esixubeneyo → isibambi sentlaka → itanki yamanzi ethotyiweyo. (3) Unyango lwangaphambili, umva i-osmosis + indlela yokuvelisa amanzi ye-EDI yamkelwe, kwaye inkqubo imi ngolu hlobo lulandelayo: Amanzi akrwada → isicacisi se-flocculation → isihluzo semidiya eninzi → isihluzo sekhabhoni esisebenzayo → isixhobo sokucoca ulwelo → umva isixhobo se-osmosis → umva itanki yamanzi ye-osmosis → EDI isixhobo → isihluzi semicroporous → itanki yamanzi edityanisiwe. Inkqubo yamanzi ekhemikhali yesityalo samandla inzima kwaye ineemfuno eziphezulu ze-asidi, i-alkali kunye nokumelana nokubola kweevalvu. Inkampani yethu inceda abathengi ukuba bakhethe iimodeli kunye ngokuhambelana neemeko zokusebenza kwindawo kwaye ibonelela ngezikimu ezihlangabezana neemeko zokusebenza kunye nokugcina uhlahlo lwabiwo-mali. Iimveliso kunye neenkonzo ziye zanconywa kakhulu ngabathengi! NJENGEZIVAVA ikakhulu zibonelela ngeevalvu zebhabhathane, iivalvu zediaphragm, iivalvu zeglowubhu, iivalvu zokujonga ibhabhathane, njl. njl. Intsimbi estainless Umgangatho wokuxhathisa i-ion ye-chloride yentsimbi engatyiwayo unokuvunywa ngokucacileyo ngokubhekisele kunyango lwamanzi ajikelezayo kwiplanti yamandla ashushu: (1) Inkonzo Ubume be-T304 yensimbi engenasici: umxholo we-chloride ion ngu-0-200mg / L (2) Ubume benkonzo ye-t316 yensimbi engenasici: umxholo we-ion ye-chloride ngu-＜ 1000mg / L (3) Indawo yenkonzo ye-t317 insimbi engenasici: umxholo we-chloride ion ngu-＜ 5000mg L Ngokutsho kwe-GB 50235-2010 ikhowudi yokwakhiwa kobunjineli bemibhobho yesinyithi kunye ne-GB 50184-2011 ikhowudi yokwamkelwa komgangatho wokwakhiwa kobunjineli bemibhobho yesinyithi, umxholo we-chloride ion emanzini awuyi kudlula i-25mg / L (25ppm). Uvavanyo lwehydraulic luya kuhambelana nezi zibonelelo zilandelayo, kwaye amanzi acocekileyo aya kusetyenziselwa uvavanyo lwehydraulic. Xa uvavanya intsimbi engatyiwayo, i-nickel kunye nemibhobho yealloyi yenikeli okanye imibhobho edityaniswe nentsimbi engatyiwa, nickel kunye nemibhobho ye-nickel alloy okanye izixhobo, umxholo we-ion yechloride emanzini awuyi kuba ngaphezu kwe-25mg / L (25ppm) Kunjani malunga ne-chloride ion ukumelana nokugqwala kwe-duplex yensimbi engenasici. ? Injani intsebenzo? I-corrosion resistance tendency ye-duplex steel stainless 2101, 2304, 2205 kunye ne-2507 inkulu kuneyesiqhelo ye-316L yensimbi engenasici, kwaye ezinye izinto zilingana nentsimbi ephezulu. Ngokomzekelo, ukunyanzeliswa kwe-corrosion ye-pitting ye-2507 insimbi engenasici ifaniswa ne-254SMO yensimbi engenasici, kunye ne-chloride ion pitting resistance corrosion resistance ye-2205 insimbi engenasici ilingana ne-904L yensimbi engenasici. Kutheni iivalvu ze-diaphragm zikhetha irabha enemigca epheleleyo? 1. Ivalve yerabha ethambileyo ye-diaphragm inokunqumla i-medium ngaphandle kokuvuza. 2. Ngenxa yokuba irabha inoxhathiso oluthile lokutya, ngaphambi kweminyaka yee-1960, kwakungekho nto ingcono ukumelana nokudleka. Iivalvu ze-diaphragm zihlala zikhuthazwa kwaye zisetyenziswe njengezinto ezinganyangekiyo kwi-corrosion, kwaye ziqhubekile ukuza kuthi ga ngoku. 3. Umzila wokuhamba ulula kwaye unomsebenzi "wokuzihlambulula", ongasetyenziselwa imidiya engcolileyo. 4. I-diaphragm eyenziwe ngokutywinwa okuthambileyo okufana nerabha okanye iplastiki inomsebenzi wokutywina kakuhle Ingxelo yomsebenzisi Indawo yomthengi ngokwakhe iphezulu kwaye ineemfuno eziphezulu zomgangatho weevalvu ezithengiweyo. Umthengi waneliseke kakhulu ngonikezelo lwe-LIKE valves. Le ntsebenziswano iye yadunyiswa kakhulu ngumthengi kwaye intsebenziswano imnandi kakhulu. Uzimisele ukugcina intsebenziswano yexesha elide kunye ne-LIKE valves. Ukubaluleka kwesivalo Ngenkqubela phambili eqhubekayo yoqoqosho lwentlalo, umzi-mveliso wamandla udlala indima ebalulekileyo kuphuhliso lwentlalo. Ke ngoko, kuphela ngokusetyenziswa ngokufanelekileyo kwenkqubo yokucocwa kwamanzi ngemichiza kunye nokuqinisekisa ngokufanelekileyo umgangatho wamanzi, inokuphuculwa indlela yokucocwa kwamanzi kwiplanti yamandla kunye neenzuzo zoqoqosho zeplanti yamandla ziyafezekiswa. Unyango lwamanzi lwekhemikhali lungundoqo ekuphuculeni ukusebenza kakuhle kokuveliswa kombane kwiziko lamandla. Idlala indima ebaluleke kakhulu ekuqinisekiseni uzinzo lokusebenza kwezixhobo ezishushu. Yinkqubo ebalulekileyo ithetha ukuphepha isikali okanye ukuqokelela ityuwa kwinkqubo yokujikeleza kwamanzi. Injongo yokuhlalutya kunye nokufunda itekhnoloji yokucocwa kwamanzi ngemichiza kwiplanti yombane kukuphucula ukusebenza kakuhle kokucocwa kwamanzi, ukunciphisa iindleko zemveliso yeziko lombane, kunye nokuphucula izibonelelo zoqoqosho nezentlalo. Iivalvu zidlala indima ebalulekileyo kumbhobho wenkqubo yokucoca amanzi ngemichiza. Khusela kwaye Gcina, NJENGEVALUVA Nceda wena!
