Ngaba uyazi ukuba zeziphi iivalvu ezisetyenziswa ngokuqhelekileyo kwiiprojekthi zokucoca amanzi?

Injongo yokucocwa kwamanzi kukuphucula umgangatho wamanzi nokwenza ukuba ahlangabezane nemigangatho ethile yobulunga bamanzi.
Ngokweendlela ezahlukeneyo zonyango, kukho unyango lwamanzi ngokwasemzimbeni, unyango lwamanzi amachiza, unyango lwamanzi ebhayoloji njalo njalo.
Ngokwezinto ezahlukeneyo zonyango okanye iinjongo, kukho iindidi ezimbini zokunyanga kwamanzi kunye nokunyangwa kwamanzi amdaka. Unyango lonikezelo lwamanzi lubandakanya ukucocwa kwamanzi okusela asekhaya kunye nokucocwa kwamanzi akwimizi-mveliso; ukucocwa kwamanzi amdaka kwahlulahlulwe kukucoca ugutyulo lwasekhaya kunye nokucocwa kwamanzi amdaka kwimizi-mveliso. Phakathi kwazo, unyango lwe-boiler feed water treatment, make-up water treatment, i-steam turbine main condensate water treatment kunye nokunyangwa kwamanzi ajikelezayo, njl. njl., zihambelana ngokusondeleyo neteknoloji ye-thermal. Ukucocwa kwamanzi kubaluleke kakhulu kuphuhliso lwemveliso yemizi-mveliso, ukuphuculwa komgangatho wemveliso, ukukhuselwa kokusingqongileyo kwabantu kunye nokugcinwa kolungelelwaniso lwendalo.
Ubunjineli bokucoca amanzi yiprojekthi yokucoca, ukuthambisa, ukubulala iintsholongwane, ukususa intsimbi kunye nemanganese, ukususa iiyoni zesinyithi esinzima, kunye nokucoca amanzi angahlangabezani neemfuno. Ukuyibeka ngokulula, "ubunjineli bonyango lwamanzi" yiprojekthi yokususa ezinye izinto ezingafunekiyo kwimveliso kunye nobomi emanzini ngeendlela zomzimba kunye neekhemikhali. Kukuzinzisa kunye nokuhluza amanzi ngeenjongo ezithile. , i-coagulation, i-flocculation, kunye neprojekthi yokulungiswa komgangatho wamanzi njengothintelo lwe-corrosion kunye nokuthintela isikali.
Ziziphi iivalvu zobunjineli bokucoca amanzi?
Ivalve yesango: Umsebenzi kukunqumla ukuhamba kwamanzi, kunye nevalve yesango enyukayo inokubona ukuvuleka kwevalve ukusuka kumphakamo wokuphakama kwesikhondo sevalve.
Ivalve yebhola: isetyenziselwa ukusika, ukusasaza kunye nokutshintsha indlela yokuhamba okuphakathi. Ngenjongo eqhelekileyo yokuvula/yokuvala iivalvu. Ayifanelekanga ukusetyenziswa njengevalve ye-throttle, kodwa ingasetyenziselwa ukunciphisa uxinzelelo olungena okanye oluphuma kwinkqubo kwindawo evulekileyo.
Ivalve yeglowubhu: Umsebenzi ophambili kumbhobho wokucoca amanzi kukunqumla okanye ukudibanisa ulwelo. Ukulawulwa kokuhamba kweglowubhuivalveingcono kunaleyo yevalve yesango, kodwa ivalve yeglowubhu ayinakusetyenziselwa ukulungisa uxinzelelo kunye nokuhamba ixesha elide, ngaphandle koko, indawo yokutywina yevalve yeglowubhu inokuhlanjwa yiCorrosion ephakathi, yonakalise ukusebenza kokutywina.
Ivalve yokujonga: isetyenziselwa ukuthintela ukuphuma ngasemva kwemidiya ngaphakathiunyango lwamanziimibhobho kunye nezixhobo.
Ivalve yebhabhathane: ukunqunyulwa kunye nokubetha. Xa iivelufa butterflyisetyenziselwa ukusika, izitywina ezilastiki zisetyenziswa kakhulu, kwaye i-material yirabha, iplastiki, njl. njl.
