Ukupholisa Tower

Umgomo Wokusebenza Wokupholisa Tower

Incazelo Yokupholisa Tower

Umbhoshongo wokupholisa idivayisi esebenzisa amanzi njengesipholisi esijikelezayo. Imunca ukushisa ohlelweni futhi ikukhiphele emkhathini ukuze yehlise izinga lokushisa lamanzi. Inqubo yakho yokupholisa incike ekuhwamukeni kwamanzi, okuvumela amanzi okupholisa ukuthi asetshenziswe kabusha futhi kuncishiswe ukumosheka kwezindleko ngokombono wezomnotho.

Ukupholisa Isimiso

Umbhoshongo wokupholisa ufutha amanzi ashisayo phezu kwezinto ezisusa ukushisa, okuwuvumela ukuthi uhlangane nomoya odlulayo. Ukushintshana kokushisa okunengqondo kwenzeka phakathi kwamanzi ashisayo nomoya obandayo, kuyilapho ingxenye yamanzi ashisayo ihwamuka futhi ikhiphe ukushisa okucashile kokuhwamuka emoyeni. Amanzi apholile awela ethangini lamanzi futhi aphonswa kwisishintshi sokushisa ukuze amunce ukushisa futhi.

Izinto Ezibalulekile Zokukhetha Umbhoshongo Wokupholisa

Imininingwane elandelayo enemininingwane iyadingeka lapho kukhethwa umbhoshongo wokupholisa:

Izinga lokugeleza kwamanzi elijikelezayo;

Ukushisa kwamanzi okungena (ashisayo) kombhoshongo wokupholisa;

Ukushisa kwamanzi okuphuma ngaphandle (okubandayo) kombhoshongo wokupholisa;

Ithempelesha yengilazi emanzi yomoya endaweni;

I-motor voltage kanye nemvamisa;

Ikhwalithi yamanzi ejikelezayo;

Izimo zemvelo zendawo kanye nendawo etholakalayo;

Uhlobo lombhoshongo oludingekayo.

Izici Zokupholisa Tower

Uhlolojikelele lwe-Counterflow Cooling Tower

Amanzi ageleza ezansi ngokwemvelo ngamandla adonsela phansi ezintweni ezisusa ukushisa, kuyilapho umoya udlula uvundlile ezintweni ezikhipha ukushisa, uhlangane nokugeleza kwamanzi nge-engeli elungile. Idizayini{1}}yokugeleza okuphambanayo yehlisa ukumelana komoya futhi inikeza umthamo womoya omkhulu uma uqhathaniswa nohlobo lokugeleza kwamanzi.

Izici

Idizayini-yokugeleza okuphambanayo inciphisa ukumelana komoya futhi yonga amandla;

Ingafaniswa nomklamo ongunxande wezakhiwo zesakhiwo sobuhle;

Yamukela idizayini{0}}yomsindo ophansi, ethobelana namazinga kazwelonke;

Izinto zokukhipha ukushisa zisebenzisa i-vacuum forming design, equkethe amandla aphezulu kanye nomphumela omuhle wokukhipha ukushisa;

Ama-fan blade asebenzisa umklamo obanzi wokulula, onejubane eliphansi lokuzungeza, umthamo womoya ophezulu nomsindo ophansi;

I-deflector yomoya ethule ifakwe ngaphansi kwediski ye-fan blade ukuvimbela ukubuyela emuva komoya, ukwandisa umthamo womoya nokunciphisa umsindo womoya;

Ifakwe iminyango yokuhlola ukuze ihlolwe kalula futhi ilungiswe;

Ingafakwa ngokuhambisana, inikeze ukusetshenziswa okuguquguqukayo nokonga amandla.

Ukupholisa Umbhoshongo Wokukhetha

Ukupholisa Izinyathelo Zokukhetha Umbhoshongo

1.1 Okokuqala, thola izinga lokushisa lamanzi angena endlini ombhoshongo wokupholisa ukuze ukhethe uhlobo olujwayelekile-lohlobo,{2}}lohlobo lwezinga lokushisa-elimaphakathi-noma{4}}lokushisa okuphezulu-lohlobo lombhoshongo wokupholisa.

1.2 Thola izidingo zomsindo ngokusekelwe kumathuluzi asetshenziswayo noma{1}}ezimeni zesayithi, bese ukhetha noma umbhoshongo wokupholisa-ogelezayo ophambanayo noma ogelezayo ophikisayo.

1.3 Khetha izinga lokugeleza kombhoshongo wokupholisa ngokwezinga lokugeleza kwamanzi okupholisa le-chiller noma umshini wesiqandisi. Ngokuvamile, izinga lokugeleza kombhoshongo wokupholisa kufanele libe likhulu kunelomshini wesiqandisi (ngokuvamile izikhathi ezingu-1.2-1.25).

1.4 Uma imibhoshongo eminingi ifakwe ngokuhambisana, zama ukukhetha imodeli efanayo yombhoshongo wokupholisa.

Amanothi Okukhethwa Kwemibhoshongo Yokupholisa

2.1 Impahla yesakhiwo sombhoshongo wombhoshongo wokupholisa kufanele izinze, iqine, ingagqwali-imelane futhi ihlanganiswe ngokunembile.

2.2 Ukusatshalaliswa kwamanzi okulinganayo, ukugeleza okuncane kodonga, ukukhetha okunengqondo kwemishini yokufutha engajwayele ukuvaleka.

2.3 Uhlobo lokugcwalisa umbhoshongo wokupholisa kufanele luhlangabezane nezidingo zekhwalithi yamanzi kanye nezinga lokushisa lamanzi.

2.4 Ifeni kufanele ifaniswe kahle ukuze kuqinisekiswe{1}}ukusebenza okujwayelekile kwesikhathi eside ngaphandle kokudlidliza noma umsindo ongajwayelekile. Ama-blade kufanele abe nokumelana nokuguguleka kwamanzi okuhle namandla anele. I-engeli yokufaka yama-fan blades iyalungiseka, kodwa ama-engeli kufanele ahambisane, futhi i-motor current akufanele idlule i-current rated.

2.5 Ukusetshenziswa kwamandla okuphansi kanye nezindleko eziphansi. Imibhoshongo yokupholisa ingilazi yohlaka lwensimbi emincane namaphakathi kufanele futhi ibe lula.

2.6 Umbhoshongo wokupholisa kufanele ugwenywe ngangokunokwenzeka eduze nemithombo yokushisa, igesi engcolile kanye nezindawo zokuphehla igesi ewuketshezi, izindawo zokugcina amakhemikhali kanye nezinqwaba zamalahle.

2.7 Ibanga eliphakathi kwemibhoshongo yokupholisa noma phakathi kwemibhoshongo nezinye izakhiwo akufanele licabangele kuphela izidingo zokungenisa umoya zemibhoshongo kanye nomthelela ofanayo phakathi kwemibhoshongo namabhilidi kodwa futhi nebanga lokuphepha komlilo nokuqhuma{1}}kwezakhiwo ezinobufakazi bokuphepha kwezakhiwo kanye nezidingo zokwakha nezokunakekelwa kwemibhoshongo yokupholisa.

2.8 Isiqondiso sepayipi lokungena lombhoshongo wokupholisa lingazungezwa ngo - 90℃, 180℃noma 270 degree.

2.9 Impahla yombhoshongo wokupholisa ingamelana nezinga lokushisa eliphansi elingu--50℃, kodwa ezindaweni lapho izinga lokushisa elijwayelekile enyangeni ebanda kakhulu lingaphansi kuka- -10℃, kufanele licaciswe lapho kufakwa i-oda lokuthatha izinyathelo zokunqanda ukuqhwala. Izindleko zombhoshongo wokupholisa zizokwenyuka cishe ngo-3%.

2.10 Ubunzima bamanzi ajikelezayo akufanele budlule ku-50mg/l, futhi bungeqi ku-100mg/l esikhathini esifushane. Akufanele ibe namabala kawoyela noma ukungcola kwemishini. Uma kunesidingo, ukususwa kwe-algae kanye nezinyathelo zokuzinzisa izinga lamanzi kufanele kuthathwe.

2.11 Uhlelo lokusatshalaliswa kwamanzi luklanywe ngokuhambisana nomthamo wamanzi okuzisholo wona. Uma umthamo wangempela wamanzi uhluka ngaphezu kuka-±15% kumthamo wamanzi ovamile, kufanele ucaciswe lapho kufakwa i-oda lokushintsha umklamo.

2.12 Ngesikhathi sokugcinwa nokuthutha, azikho izinto ezisindayo okufanele zibekwe ezingxenyeni zombhoshongo wokupholisa, futhi akufanele zivezwe elangeni eliqondile. Ukuvimbela umlilo kufanele futhi kuqashelwe. Ngesikhathi sokufakwa, ukuthuthwa nokunakekelwa kombhoshongo wokupholisa, amalangabi avulekile njengokushisela ugesi nokushisela igesi akufanele kusetshenziswe, futhi iziqhumane neziqhumane akufanele zicishwe eduze.

2.13 Ngokuklanywa kwemibhoshongo eyindilinga eminingi, ibanga lenethi phakathi kwemibhoshongo kufanele libe okungenani izikhathi ezingu-0.5 kunobubanzi bombhoshongo. Imibhoshongo-egelezayo ne-counterflow square towers ingahlelwa ngokuhambisana.

2.14 Iphampu yamanzi ekhethiwe kufanele ihambisane nombhoshongo wokupholisa ukuze kuqinisekiswe izidingo zenqubo ezifana nezinga lokugeleza nokuphakamisa.

2.15 Lapho ukhetha imibhoshongo yokupholisa eminingi, khetha imodeli efanayo ngangokunokwenzeka.

Isondlo

Amanzi amaningi okupholisa aqukethe i-calcium ions, i-magnesium ion nama-bicarbonates. Lapho amanzi okupholisa egeleza endaweni yensimbi, kwakheka isikali se-carbonate. Ngaphezu kwalokho, i-oxygen encibilika emanzini apholisayo nayo ingabangela ukugqwala kwensimbi futhi kubangele ukugqwala. Ngenxa yokwakheka kokugqwala nesikali, ukusebenza kahle kokushintshaniswa kokushisa kombhoshongo wokupholisa kuncipha. Ezimweni ezimbi kakhulu, kuyadingeka ukufafaza amanzi okupholisa ngaphandle kwegobolondo. Ukukala okunzima kungavimba amapayipi futhi kwenze umphumela wokushintshanisa ukushisa ungasebenzi. Idatha yocwaningo ibonisa ukuthi amadiphozithi esikali anomthelela omkhulu ekulahlekeni kokudluliswa kokushisa. Ukwenyuka kwamadiphozithi kuzoholela ezindlekweni zamandla aphezulu. Ngisho nongqimba oluncane lwesikali lungakhuphula izindleko zokusebenza zengxenye elinganiselwe yezinto zokusebenza ezingaphezu kuka-40%. Ukugcina iziteshi zokupholisa zingenawo amadiphozithi amaminerali kungathuthukisa ukusebenza kahle, konga amandla, kunwebe isikhathi sokusebenza kwezinto zokusebenza, futhi konge isikhathi sokukhiqiza nezindleko. Isikhathi eside, izindlela zokuhlanza ezivamile ezifana nezindlela zemishini (ukuklwebha, ukuxubha),{11}}amanzi anengcindezi ephezulu, nokuhlanza amakhemikhali (ukuvuna) ziye zahlangabezana nezinkinga eziningi lapho zihlanza izinto zokusebenza: azikwazi ukususa ngokuphelele isikali nezinye izinto ezifakwayo, isixazululo se-asidi sigqwalisa okokusebenza ukuze kwakhe izimbobo, futhi i-asidi esele ibangela ukugqwala kwesibili noma ngaphansi{12} kokugqwala kuya esikalini sokushintshwa. Ngaphezu kwalokho, uketshezi lwemfucuza yokuhlanza lunobuthi futhi ludinga imali eningi yokuhlanza amanzi angcolile.
