Ngaba uyazi ukuba zeziphi iivalvu ezisetyenziswa rhoqo kwiiprojekthi zokunyanga amanzi?

Injongo yokucocwa kwamanzi kukuphucula umgangatho wamanzi nokwenza ukuba ahlangabezane nemigangatho ethile yomgangatho wamanzi.
Ngokweendlela ezahlukeneyo zonyango, kukho unyango lwamanzi ngokwasemzimbeni, unyango lwamanzi ngamakhemikhali, unyango lwamanzi ngokwebhayoloji njalo njalo.
Ngokweenjongo ezahlukeneyo zonyango, kukho iintlobo ezimbini zokunyanga amanzi kunye nokunyanga amanzi amdaka. Ukunyanga unikezelo lwamanzi kuquka ukunyanga amanzi okusela ekhaya kunye nokunyanga amanzi emizi-mveliso; ukunyanga amanzi amdaka kwahlulwe ngonyango lwamanzi amdaka ekhaya kunye nokunyanga amanzi amdaka kwimizi-mveliso. Phakathi kwazo, ukunyanga amanzi okutya ngebhoyila, ukunyanga amanzi okuzilungisa, ukunyanga amanzi e-condensate aphambili kwi-turbine kunye nokunyanga amanzi ajikelezayo, njl.njl., zinxulumene kakhulu netekhnoloji yobushushu. Ukunyanga amanzi kubaluleke kakhulu kuphuhliso lwemveliso yemizi-mveliso, ukuphuculwa komgangatho wemveliso, ukukhuselwa kokusingqongileyo kwabantu kunye nokugcinwa kolungelelwaniso lwendalo.
Ubunjineli bonyango lwamanzi yiprojekthi yokucoca, ukuthambisa, ukubulala iintsholongwane, ukususa isinyithi kunye ne-manganese, ukususa ii-ion zesinyithi ezinzima, kunye nokucoca amanzi angahlangabezani neemfuno. Ngamafutshane, "ubunjineli bonyango lwamanzi" yiprojekthi yokususa ezinye izinto ezingafunekiyo kwimveliso kunye nobomi emanzini ngeendlela zomzimba nezekhemikhali. Kukuhlalisa nokucoca amanzi ngeenjongo ezithile. , ukujiya, ukuqunjelwa, kunye neprojekthi yokulungisa umgangatho wamanzi njengokuthintela ukugqwala kunye nokuthintela isikali.
Zithini iivalvu zobunjineli bokucoca amanzi?
Ivalvu yesango: Umsebenzi wayo kukunqumla ukuhamba kwamanzi, kwaye ivalvu yesango lesiqu esinyukayo ikwabona ukuvuleka kwevalvu ukusuka kubude bokuphakamisa besiqu sevalvu.
Ivalvu yebhola: isetyenziselwa ukusika, ukusasaza nokutshintsha indlela yokuhamba okuphakathi. Ngenjongo eqhelekileyo iivalvu zokuvula/ukuvala. Ayifanelekanga ukusetyenziswa njengevalvu yokuthomalalisa, kodwa ingasetyenziselwa ukunciphisa uxinzelelo olungena okanye oluphuma kwinkqubo kwimeko evulekileyo kancinci.
Ivalvu yeglobe: Umsebenzi ophambili kumbhobho wokucoca amanzi kukunqumla okanye ukudibanisa ulwelo. Ukulawula ukuhamba kweglobeivalvuingcono kuneyevalvu yesango, kodwa ivalvu yeglobhu ayinakusetyenziswa ukulungisa uxinzelelo kunye nokuhamba kwexesha elide, kungenjalo, umphezulu wokutywina wevalvu yeglobhu unokuhlanjwa yi-medium Corrosion, oko konakalise ukusebenza kokutywina.
Ivalvu yokujonga: isetyenziselwa ukuthintela ukubuya kwe-media kwiunyango lwamanziimibhobho nezixhobo.
Ivalvu yebhabhathane: ukunqunyulwa kunye nokuqhoboshelwa. Xaivalvu yebhabhathaneisetyenziselwa ukusika, izitywini ze-elastic zisetyenziswa kakhulu, kwaye izinto ezisetyenzisiweyo zerabha, iplastiki, njl. Xa zisetyenziselwa ukuqhobosha, izitywini zesinyithi eziqinileyo zisetyenziswa kakhulu.
