Ivaliwe-I-Circuit Cooling Tower for High-IFrequency Furnace

 

 

 

Iuvaliwe{0}umbhoshongo wokupholisa oyisekhethiokuhlinzekelwe-iziko eliphezulu{1}}izisetshenziswa zokupholisa ezisebenza kahle eziklanyelwe ngokukhethekile-ukushisisa okungeniswa imvamisa, ukuncibilika, ukucisha nezinye izinto zokusebenza. Umongo wayo ukuzivumelanisa nomthwalo wokushisa ophezulu kanye nezidingo eziqinile zekhwalithi yamanzi ngesikhathi sokusebenza-kweziko eliphezulu. Ngedizayini evaliwe yokushintsha ukushisa kwe-loop, ixazulula izindawo ezibuhlungu zemibhoshongo evamile yokupholisa njengokukala okulula nokugqwala kwemishini, iqinisekisa{7}}ukusebenza okuzinzile kwesikhathi eside kwezingxenye ezibalulekile{8}}zezifudumezi zefrikhwensi ephezulu, futhi iyisisetshenziswa esibalulekile esisekelayo{9}}ilayini yokukhiqiza ifrikhwensi ephezulu. Inzuzo yayo eyinhloko isekujikelezweni kwendilinga{11}}okuvaliwe kwendawo yokupholisa ngaphakathi kwepayipi, okungathinti ngokuqondile umoya wangaphandle. Ayikwazi nje ukususa ukushisa kahle, kodwa futhi igweme ukungcoliswa kwamanzi futhi yandise impilo yesevisi{13}}yeziko lamaza aphezulu.

 

 

 

 

 

Uma-isithando somlilo esiphezulu sisebenza, izingxenye ezibalulekile ezifana namakhoyili angeniswayo, amamojula wamandla e-IGBT, ama-thyristors, nama-capacitor bank azophehla ukushisa okuningi khona manjalo. Uma ukupholisa kungenasikhathi, izinga lokushisa elidlulele lizoholela ekugugeni kwengxenye, isifunda esifushane noma ngisho nokutubeka, okuthinta ngokuqondile ukusebenza kahle kokukhiqiza nokuphepha kwemishini. Ngenxa yokuthi indawo yokupholisa yezakhiwo zokupholisa ezivamile ezivulekile ithintana ngqo nomoya, kulula ukuyixuba nothuli nokungcola, ukwenza isikali ukuze kuvinjwe amapayipi futhi kugqwese izingxenye ezinembayo{3}}zeziko lamafrikhwensi aphezulu. Umbhoshongo wokupholisa wesekhethi ovaliwe-uxazulula le nkinga ewumongo futhi ulungele izimo zokusebenza zokusebenza okuqhubekayo kanye{6}}nokusebenza kwezinga lokushisa okuphezulu{6}}kweziko{7}}zemvamisa ephezulu.

 

 

 

Umgomo wayo wokusebenza wamukela imodi yokushintshanisa ukushisa okubili "yokujikeleza kwangaphakathi okuvaliwe + ukujikeleza kwangaphandle kokufutha", okucabangela kokubili ukusebenza kahle kokupholisa kanye nokuvikelwa kwekhwalithi yamanzi. Kusekhethi yangaphakathi evaliwe, amanzi athambile noma ingxube ye-ethylene glycol (i-anti-iqhwa kanye ne-anti{3}}i-corrosion) ithunyelwa ezingxenyeni zokushisisa zesithando somlilo{4}}semvamisa ngephampu ejikelezayo, ifudunyezwe ngemva kokumunca ukushisa, bese igelezela kukhoyili yokushintsha ukushisa kombhoshongo wokupholisa; kusifutho sangaphandle nesekhethi yokupholisa umoya, isiphephetha-moya sidonsa umoya wokushisa ovamile ngenkani, ogeleza ebusweni bekhoyili ukuze uthole ukushintshaniswa kokushisa okuyisisekelo. Ku-izinkathi zokushisa eziphezulu noma umthamo ophakeme kakhulu, isistimu yokufutha iqala ngokuzenzakalelayo, ifafaze amanzi ngokulinganayo odongeni olungaphandle lwekhoyili, futhi isebenzisa ukushisa okucashile kokuhwamuka kwamanzi ukuze kuthuthukiswe umphumela wokushintshanisa ukushisa futhi kuthuthukise kakhulu ukusebenza kahle kokupholisa. Umoya oshisayo noswakeme uyaphuma ngemva kokuhlukanisa amaconsi amanzi ngomqoqi wamanzi, futhi amanzi afuthwayo ageleza abuyele ku-sump ukuze agaywe kabusha, adinga kuphela inani elincane lamanzi angeziwe ukuze ahwamuke kanye nokulahlekelwa ukukhukhuleka, okunomphumela wokulondoloza amanzi{1}}obalulekile. Ngesikhathi esifanayo, imishini ifakwe uhlelo lokulawula oluhlakaniphile, olungashintsha ngokuzenzakalelayo phakathi kwezindlela ezomile nezimanzi ngokuvumelana nezinga lokushisa elizungezile kanye nezinga lokushisa eliphakathi nendawo, ukuqapha izinga lokushisa, ingcindezi kanye nezinga lamanzi ngesikhathi sangempela, kanye ne-alamu uma kwenzeka izinto ezingavamile, ukunciphisa ukusebenza ngesandla kanye nezindleko zokunakekelwa.

 

 

 

 

 

 

Isakhiwo esiyinhloko siklanywe ngendlela efanele eduze nezimo zokusebenza-zezithando zefrikhwensi eziphezulu, ikakhulukazi ezihlanganisa igobolondo lenjini eyinhloko, ikhoyili yokushintsha ukushisa, ifeni, isistimu yesifutho, isiqoqi samanzi, iphampu ejikelezayo kanye nesistimu yokulawula ehlakaniphile. Igobolondo lenjini eyinhloko lenziwe ngensimbi engagqwali noma ishidi likathayela, elingangenwa amanzi, -elingagqwali futhi limelane nezinga lokushisa eliphezulu{3}}elivumelana nemvelo eyinkimbinkimbi yezindawo zokusebenzela zezimboni; ikhoyili yokushintshanisa ukushisa yenziwe ngethusi noma ngensimbi engagqwali engu-316, ene-conductivity ephezulu yokushisa kanyeukumelana nokugqwala,okungamelana ngempumelelo-nokuguguleka kwesikhathi eside kwendawo epholile futhi kugweme ukuvuza okuphakathi okubangelwa ukulimala kwamakhoyili; ifeni ithatha{1}}imodeli ephansi yomsindo kanye{2}}esebenza kahle kakhulu, icabangela kokubili umphumela wokupholisa kanye nendawo yokusebenzela; umqoqi wamanzi wenziwa-ngezinto eziphezulu ze-hydrophilic, ezingakhulisa ukutholakala kwamaconsi amanzi okufuthwa, ukunciphisa ukungcola kwamanzi kanye nomthelela emvelweni; iphampu ezungezayo iyimodeli ephezulu-emelana nengcindezi futhi iphansi-imodeli yomsindo ophansi, eqinisekisa ukuzungeza okushelelayo kwendawo epholile futhi ehlangabezana nezidingo zokupholisa zomthwalo osheshayo wokushisa okuphezulu{6}}kweziko eliphezulu{6}}.

 

 

 

 

 

 

Uma kuqhathaniswa nemibhoshongo yokupholisa evamile, iuvaliwe{0}umbhoshongo wokupholisa oyindilinga onikezelwekumafurnace{0}emvamisa ephezulu kunezinzuzo ezine ezibalulekile: okokuqala, ikhwalithi yamanzi ahlanzekile. Ukujikeleza okuvaliwe kugwema ukuxutshwa kokungcola, kuqede ukukala nokuvinjwa, kuvikela izingxenye ezinembayo zesithando somlilo{2}}esivamile, futhi kunciphisa ukuhluleka kwemishini; okwesibili, ukusebenza kahle kokupholisa okuphezulu. Imodi yokushintshanisa ukushisa okukabili ijwayela ukushintsha komthwalo ophezulu kanye nokuphansi kwesithando somlilo{4} esinemvamisa ephezulu, enesivinini sokupholisa esisheshayo, okuqinisekisa ukuthi okokusebenza kusebenza ezingeni lokushisa elilinganiselwe isikhathi eside; okwesithathu, ukonga amandla kanye nokuvikelwa kwemvelo. Izinga lokonga amanzi lingafinyelela ngaphezu kuka-80%, idizayini yomsindo ephansi-ihlangabezana nezindinganiso zokuvikela indawo yemboni, futhi ukulawula izinga lokushisa okuhlakaniphile kunciphisa ukusetshenziswa kwamandla; okwesine, impilo ende yesevisi. Izingxenye eziyinhloko zenziwe{9}ngezinto ezikwazi ukumelana nokugqwala{10}}zekhwalithi ephezulu, ezinomklamo ophusile wesakhiwo kanye nokusebenza okulula nokunakekelwa, futhi impilo yesevisi yinde ngeminyaka emi-3-5 kunemibhoshongo yokupholisa evamile.

 

 

 

 

 

 

Lesi sisetshenziswa sisetshenziswa kakhulu ezintweni ezihlukene zokushisisa{0}}ezijwayelekile, okuhlanganisa{1}}iziko ezincibilika imvamisa,{2}}iziko ezicisha imvamisa,{3}}imishini yokushisisa imvamisa, njll., futhi ifanele ukwenziwa kwensimbi, ukukhiqizwa kwemishini, ukucutshungulwa kwehardware, izingxenye zemishini yezimoto nokunye. Lapho ukhetha amamodeli, kuyadingeka ukukhetha ngokunengqondo amamodeli ngokuya ngamandla, umthwalo wokushisa kanye nezinga lokushisa lendawo yokusebenza yesithando somlilo esikhulu{6}}sefrikhwensi, kuhlanganiswe nevolumu yamanzi okupholisa kanyeukupholisa isidingo, ukuqinisekisa ukuthi umthamo wokupholisa ufana nempahla, futhi ugweme ukuthikameza umphumela wokupholisa kanye nokuphepha kwemishini ngenxa yokukhetha okungafanele kwemodeli. Ukusebenza nokugcinwa kwansuku zonke kudinga kuphela ukuhlola njalo isistimu yesifutho, ukuhlanza isihlungi kanye nokwengeza indawo yokupholisa ukuze kuqinisekiswe ukusebenza okuzinzile kwesisetshenziswa kanye nokuphelezela{1}}ulayini wokukhiqiza isithando somlilo omningi.
