Ngaphandle kwexabiso eliphezulu, iitanki zesifudumezi samanzi zentsimbi engenastainless zixabisa kakhulu xa kuthelekiswa neendleko zomjikelo wobomi kwaye kufuneka zinikezelwe ngolo hlobo.
Izifudumezi zamanzi zasekhaya ziintsana zangempela zehlabathi lomatshini.Bahlala bevezwa kwiindawo ezinzima kakhulu kwaye umsebenzi wabo onzima awuhoywa kakhulu.Ecaleni lamanzi le-heater, iiminerali, ioksijini, iikhemikhali kunye nentlenga zonke zihlaselwa.Xa kufikwa ekutshiseni, ukushisa okuphezulu, uxinzelelo lwe-thermal, kunye ne-flue gas condensate inokonakalisa zonke izinto.
Xa kufikwa kulondolozo, izifudumezi zamanzi ashushu zasekhaya (DHW) zonke azihoywanga.Abaninimzi abaninzi bazithatha kancinci izifudumezi zabo kwaye baziqaphela kuphela xa zingasebenzi okanye zivuza.Jonga intonga ye-anode?Sula intlenga?Ngaba sikho isicwangciso sokulondoloza?Yilibale, asikhathali.Akumangalisi ukuba uninzi lwezixhobo zeDHW zinobomi obufutshane.
Ngaba obu bomi bufutshane bunokuphuculwa?Ukusebenzisa izifudumezi ze-DHW ezenziwe ngensimbi engenasici yindlela enye yokwandisa ubude bokuphila.Insimbi engenasici yinto eyomeleleyo kunye neyomeleleyo enika ukuchasana okungcono emanzini kunye nokuhlaselwa komlilo, ukunika i-heater ithuba lokubonelela ubomi benkonzo ende.Ukuphela kokwenyani kwinsimbi engenasici yixabiso eliphezulu lezinto eziphathekayo kunye nokuveliswa.Kwixabiso eliphezulu lokukhuphisana kwe-DHW, i-DHW ixabisa kakhulu i-heater.
Intsimbi engatyiwayo ligama eliqhelekileyo lealloyi ezibolileyo kunye nomxholo wechromium ubuncinane we-10.5%.Ezinye izinto ezifana nenickel, molybdenum, titanium kunye nekhabhoni nazo zingongezwa ukunika ukuxhathisa umhlwa, ukomelela kunye nokwakheka. Kukho indibaniselwano ezininzi ezahlukeneyo zezi ngxubevange zentsimbi zahlukeneyo ezivelisa "iintlobo" ezithile kunye nokuthi "into engatshintshiyo yentsimbi ayithethi ngentsimbi engatyiwayo."
Ukuba umntu uthe "ndinike imibhobho yeplastiki" ubuya kuzisa ntoni? I-PEX, i-CPVC, i-polyethylene? Zonke ezi ziyimibhobho "yeplastiki", kodwa zonke zineepropati ezihluke kakhulu, amandla kunye nezicelo. Okufanayo kuya kwi-stainless steel. Kukho ngaphezu kwe-150 amabakala ensimbi engenasici, zonke zineepropati ezahlukeneyo kunye nezicelo. , 316Ti kunye ne-444.
Umahluko phakathi kwala mabanga kukugxininiswa kwe-alloy kuwo.Zonke "i-300" ze-stainless steels zebakala ziqulethe malunga ne-18% yechromium kunye ne-10% ye-nickel.Amabakala amabini angama-316 nawo aqulethe i-2% ye-molybdenum, ngelixa i-316Ti ibakala ine-1% ye-titanium eyongeziweyo kumxube. ukuxhathisa kwimingxuma kunye nokuhlwa kwemingxuma kwindawo yekhloride.316Titanium yodidi lwe-316Ti iyenza ikwazi ukumila kakuhle nokomelela.Ibanga lama-444 linayo ichromium kunye nemolybdenum, kodwa ayinayo nickel. Ngokuqhelekileyo, okukhona nickel, imolybdenum, kunye netitanium kumxube, kokukhona iba ngcono kwaye inamandla okumelana nesixhobo sokufudumeza amanzi, kodwa i-heater iyayixabisa kakhulu. , wajonge ngenyameko amabanga njengoko engengawo umgangatho ofanayo
Insimbi engenasici isetyenziswe kuzo zonke iintlobo ezahlukeneyo zokufudumala kwamanzi.Isetyenziswa ngokuqhelekileyo kwii-heaters ze-DHW ezingathanga ngqo kunye ne-condensing water heaters.Izifudumezi zamanzi ezingenasiphelo ziqulethe i-coil yokudlulisa ukushisa yangaphakathi edibeneyo kwibhoyili okanye i-solar collector loop.Zixhaphake kakhulu eYurophu kunaseCanada ngenxa yolawulo lwe-European hydro kunye neenkqubo zokufudumeza kwamanzi elanga.
Ulwakhiwo lwentsimbi estainless lubandakanya inxalenye enkulu yezi marike zaseYurophu ezingathanga ngqo.ECanada, iitanki zentsimbi engenanto kunye neglasi-efakwe ngeglasi yentsimbi engathanga ngqo ziyafumaneka, iitanki zetsimbi yentsimbi zihlala zinexabiso eliphezulu. Kwizifudumezi zamanzi ezingenatanki ezingacondensing, umtshintshisi wobushushu udla ngokwenziwa ngobhedu. izifudumezi zamanzi zihlala zingukumkani kwimarike yesifudumezi samanzi saseKhanada.Intsimbi yekhabhoni eneglasi yentsimbi ilawula le segment.Intsimbi engasebenziyo iqhele ukusetyenziswa kwitanki engenatanki okanye ethe ngqo efakwa kwitanki ejingisa amanzi.
Ukwandisa ukusebenza kakuhle kwezi zixhobo, irhasi yeflue kufuneka ipholiswe ngaphantsi kwendawo yombethe ukukhulula ubushushu obufihlakeleyo bamafutha.Isiphumo secondensate ngumphunga wamanzi adiyiweyo osuka kwiimveliso zokutsha zegesi, ezinepH ephantsi kakhulu kunye nobumuncu obuphezulu.
Abatshintshi bokushisa okwenziwe ngentsimbi eqhelekileyo okanye ubhedu kunzima ukujamelana nale gesi ye-condensate ixesha elide.Insimbi engenasici yinto efanelekileyo yokukhetha izinto eziphathekayo ngenxa yokumelana nokunyuka kwe-corrosion kunye nokuguquguquka, ukuvumela ukuba yenze imilo enzima yokutshintshiselana kobushushu.Kukho iintlobo ezininzi ze-condensing tankless water heaters ezisebenzisa insimbi engenasici kunye ne-gardeneration ye-stainless steel stainless kunye ne-gardeneration ye-EF evumela ukuba bakhuthaze ukufudumala kwe-EF. ukuya kuthi ga kwi-0.97.
Izifudumezi zamanzi zetanki ezinobuchwephesha bokudibanisa nazo ngoku ziqala ukusetyenziswa rhoqo, ngakumbi ngolunye utshintsho lwekhowudi yokwakha efuna ukusebenza kakuhle kwesifudumezi samanzi. Kukho iindidi ezimbini zokwakha eziqhelekileyo kule marike.Iitanki ezifakwe ngeglasi zakha ngokupheleleyo ukuntywiliselwa kwesibini okutshintshiselana kobushushu.Ngaphandle (icala lamanzi) kunye nangaphakathi (icala lomlilo) leekhoyili zokutshintsha ubushushu zifakwe kwiglasi-ezifakwe kwiglasi-ezineglasi-zifakwe kwi-ganne-lined ngaphakathi kweglasi-i-Galasi efakwe kwiglasi ngaphakathi. itanki yensimbi engenasiphelo kunye nokwakhiwa kweekhoyili azixhaphakanga, kodwa kukho ulwakhiwo oluninzi olunjalo lwensimbi engenasici.
Iindleko zokuqala zetanki eneglasi ziphantsi ngokwenene, kwaye lixesha kuphela eliya kuxela ukuba ukumelana nobushushu kuya kuba njani kwiimeko ezixinzelelekileyo.Ezi zifudumezi zamanzi zetanki ezintsha ze-condensate ziyakwazi ukuphumeza ukusebenza okuphezulu kunezifudumezi zamanzi ezitshisiweyo ezithe ngqo, kunye nokuphumelela kwe-thermal ukusuka kwi-90% ukuya kwi-96%. .
Jonga ngononophelo izifudumezi zamanzi zetanki kwaye uya kufumanisa ukuba uninzi lweentlobo zokutshiselwa ngokuthe ngqo, iikhoyili zangaphakathi ezingathanga ngqo, kunye neetanki zokugcina ezithe tye zineglasi-ezineglasi kunye nolwakhiwo lwentsimbi engenasici.
Ngoko ke, ziziphi iingenelo zensimbi engenasici phezu kweglasi efakwe? Uqinisekisa njani abathengi ukuba batyale imali ngakumbi kwiitanki zentsimbi? Eyona nzuzo inkulu yensimbi engenasici kukumelana kwayo kwendalo kwi-corrosion yamanzi ahlaziyekileyo, okwandisa ubomi benkonzo.Ngenxa yokubunjwa kwayo kwe-alloys yentsimbi enganyangekiyo, iitanki zensimbi ezingenasici zinamandla kwaye zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zikhuselekile. umbono.
Iitanki ezineglasi, kwelinye icala, zithembele kwiglasi-ezifakwe kwiglasi ukubonelela umqobo phakathi kwe-carbon steel kunye namanzi.Ukunika ithuba, i-oksijini kunye neekhemikhali ezisemanzini ziya kuhlasela intsimbi kwaye ziyidle ngokukhawuleza.Kuba phantse akunakwenzeka ukusebenzisa nayiphi na i-coating yokukhusela ngokugqibeleleyo (akukho kuphazamiseka kwe-microscopic okanye iziphene ze-pinhole kwi-tank yokukhusela i-tank ye-tank yokukhusela i-tank ye-tank ekhuselweyo ngaphakathi kwe-tank ye-rocridline ye-glass-sacrid.
Izibonda ze-anode zedini ziya kuguga ngokuhamba kwexesha, kwaye xa inkqubo igqityiwe, i-electrolysis iya kuqala ukutshabalalisa iindawo zetsimbi eziveziweyo ngaphakathi kwetanki.Izinga apho i-anode iyancipha ixhomekeke kumgangatho wamanzi kunye nomthamo wamanzi asetyenzisiweyo.I-anodes yombingelelo ngokuqhelekileyo ihlala iminyaka emithathu ukuya kwemihlanu, kwaye i-anode inokutshintshwa ukuze ithintele umonakalo omkhulu.
Enyanisweni, ukuhlolwa rhoqo kunye nokutshintshwa kwe-anodes kudla ngokungahoywa, kwaye itanki ivuza, ibangela ukuba yonke iyunithi ithathelwe indawo.Ngokungafaniyo neetanki ezifakwe kwiglasi, iitanki zensimbi ezingenasici azidingi "i-anodes yedini" ukukhusela ukubola kwiindawo zabo.Oku kuthetha ukuba akukho mfuneko yokuhlola okanye ukubuyisela indawo ye-anode, ukugcina ixesha lokugcinwa kwamanzi kunye neendleko zokushisa kwamanzi phezu kobomi.
Ngenxa yokonyuka kokuqina kunye nokumelana nomhlwa, uya kuhlala ufumana iitanki zentsimbi engenaziqinisekiso zinewaranti ende, kunye nabavelisi abathile banikezela ngeziqinisekiso zobomi beetanki.
Iitanki zensimbi ezingenasici nazo zinenzuzo yokuba zikhaphukhaphu xa zithelekiswa neitanki ezifakwe kwiglasi, okwenza kube lula ukuthuthwa, ukuphatha kunye nokufaka.Ubukhulu bodonga lwentsimbi engenasici esetyenziswe kwiitanki ngokuqhelekileyo buncinci kakhulu kuneetanki zetsimbi ezifanayo kunye neglasi.
Ngokungafani neengqayi ezifakwe kwiglasi, izimbiza zetsimbi ezingenasici zifuna ingqalelo encinci xa zithunyelwa, kwaye i-glass lining inokonakala ngexesha lokuthutha.Ukuba iglasi yeglasi yetanki yonakaliswe okanye iqhekezwe ngenxa yokuphathwa kakubi ngexesha lokuthunyelwa okanye ukufakela, akuyi kwaziwa de itanki iphumelele ngaphambi kwexesha.
Iitanki zensimbi ezingenasici ngokuqhelekileyo ziyakwazi ukumelana nokushisa kwamanzi aphezulu kunamatanki afakwe kwiglasi, kwaye amaqondo okushisa angaphezu kwe-180F akayi kunika nayiphi na ingxaki.Amanye amatanki afakwe ngeglasi axhomekeke ekugxininiseni kwiqondo lokushisa eliphezulu, okubangelwa umngcipheko ophezulu womonakalo owenziwe ngeglasi.Iiqondo lokushisa elingaphezulu kwe-160F linokuba yingxaki kwezinye iilayini zeglasi.Izicelo zokushisa zamanzi eziphakamileyo ezifana nezixhobo zokugcina amanzi zorhwebo ziyakwazi ukubona i-solar water heaters.
Kucetyiswa ukuba udibane nomenzi wetanki eneglasi yeqondo lokushisa eliphezulu elicetyiswayo.Iitanki zetsimbi ezingenasici zidla ngokukhetha ukhetho olungcono kwizicelo zokushisa okuphezulu.
Akungabazeki ukuba iindleko zokuqala zetanki zensimbi ezingenasici ziphezulu kunetanki ene-glass-lined.Kodwa ngenxa yezizathu ezikhankanywe apha, iindleko zomjikelo wobomi betanki ene-glass-lined zingaba phezulu.Xa uthelekisa ezi ndleko zomjikelo wobomi, iitanki zensimbi ezingenasici ngokuqhelekileyo zineendleko eziphezulu kwixesha elide kwaye kufuneka ziboniswe kubathengi.
