Izinto Ezikhethwayo Zezakhiwo Ezipholile Ezivaliwe-zeCircuit Cooling Towers

Isici esiyinhloko se-counterflow evaliwe-imibhoshongo yokupholisa eyisekhethi ukugeleza okuphikisayo koketshezi olupholisayo nomoya, okuholela ekusebenzeni kahle kokushintshaniswa kokushisa. Zifanele ikakhulukazi-izimo zokupholisa umehluko wezinga lokushisa eliphezulu, njengokupholisa{3}}inqubo yezinga lokushisa eliphezulu ku-metallurgy, casting, chemical, nezinye izimboni. Izinzuzo zabo zihlanganisa usayizi wemishini encane, indawo encane yaphansi, isisindo esincane, indawo enkulu yokupholisa yamashubhu ethusi angenalutho, impilo ende yesevisi, kanye nokuvumelana nezimo zokusebenza-eziphezulu. Ububi ukuthi banezidingo eziphezulu zokufana kwesifutho; ukusatshalaliswa kwamanzi okungalingani kungaholela kalula ekunciphiseni ukusebenza kahle kokushintshaniswa kokushisa kwendawo. Imibhoshongo yokupholisa ye-Crossflow evaliwe{8}}yeziyingi isebenzisa idizayini lapho uketshezi olupholisayo nomoya ugeleza ngokunqamulayo. Amanzi{10}}asezingeni lokushisa eliphezulu afuthwayo aqale apholiswe ngesendlalelo sokugcwalisa bese eshintshanisa ukushisa ngekhoyili, okuwenza afaneleke kakhulu{11}}ezidingweni zokupholisa{11}}ezinomehluko wezinga lokushisa ophakathi nendawo. Lolu hlobo lomkhiqizo lunesakhiwo esilula futhi lulungele ukufakwa nokunakekelwa, kodwa luthatha indawo enkulu, ludinga{13}}ukuhlanganiswa kwesayithi, futhi kunzima ukuthuthwa.

 

 

 

Ukugeleza kwenhlanganisela kuvaliwe-imibhoshongo yokupholisa eyiziyingi ihlanganisa izinzuzo zedizayini ze-counterflow nezinhlobo ze-crossflow. Basebenzisa amashubhu ekhopha njengesiphathi esiyinhloko sokudlulisa ukushisa futhi zengezwe ngenani elincane lokugcwaliswa kwe-PVC ukuze kuthuthukiswe imiphumela yokupholisa, ephinde ifanele izimo zokuhluka{2}}ezimaphakathi neziphansi. Izici zabo zihlanganisa ukusebenza kahle kokupholisa okulinganiselwe, ukumelana nokugqwala okuqinile, kanye nomklamo ohlangene wamapaneli angaphandle ensimbi kanye nezingubo ezikhethekile ezingakwazi ukuzivumelanisa nezimo eziyinkimbinkimbi, kodwa ivolumu yemishini inkulu kancane kunemikhiqizo ephikisanayo. Umehluko ekusebenzeni okubalulekile kwezinhlobo ezintathu zemikhiqizo uhlinzeka ngezikimu zokukhetha eziqondiwe ezimweni ezihlukene zezimboni.

 

 

 

Ezisetshenziswa ezingokoqobo, izinhlobo ezihlukene zemibhoshongo yokupholisa zinezigaba ezihambisanayo zokulawula ze-COC, ezidinga ukusethwa ngokunembile ngokuya ngohlobo lwemishini, ikhwalithi yamanzi, nendawo yokupholisa. Okwasetshenziswa kakhulucounter-geleza vula-imibhoshongo yokupholisa eyisekhethi, ngenxa yokuxhumana okuqondile phakathi kwamanzi ajikelezayo nomoya, ikhwalithi yamanzi ishintshashintsha kakhulu, futhi uhla lokulawula i-COC olunengqondo3-5 imijikelezo. Ngoba-ukugeleza kuvaliwe-imibhoshongo yokupholisa eyindilinga, idizayini yabo evaliwe-yokuzungeza umjikelezo wehlisa ukungcoliswa kwekhwalithi yamanzi, ngakho inani le-COC linganyuswa ngokufanelekile ukuze libe5-8 imijikelezo. Ezimweni ezinezidingo zekhwalithi ephezulu yamanzi, njengamasistimu omoya ophakathi{1}}okugcina ukushisa, inani le-COC livamise ukulawulwa ngaphakathi.3-4 imijikelezoukugwema ukukala okuthinta ukusebenza kahle kwesiqandisi. Ngaphezu kwalokho, ubulukhuni bamanzi okwakheka kuzophinde kuthinte ukumiswa kwenani le-COC. Lapho ubulukhuni bamanzi ezimonyo buphezulu, inani le-COC kufanele lehliswe ngokufanelekile ukuze kuncishiswe ingozi yokukala.

 

 

Amabhizinisi adinga ukugxila kulawa maphuzu abalulekile alandelayo lapho ekhetha amamodeli: Okokuqala, cacisa imingcele yenqubo, okuhlanganisa izinga lokugeleza, izinga lokushisa le-inlet ne-outlet, ukucindezela, nokwakheka okuphakathi koketshezi oluzopholiswa, ukuze kunqunywe umthamo wokupholisa kanye nezinto zamakhoyili wombhoshongo wokupholisa. Okwesibili, cabanga ngezimo zemvelo: ezindaweni-ezisezingeni eliphezulu nezinomswakama ophezulu{2}}ezindaweni ezinomswakama ophezulu, kufanele kubekwe kuqala ekuqinisekiseni ukusebenza kahle kokukhipha ukushisa okuhwamukayo; ezifundeni ezibandayo ezisenyakatho, kufanele kuqashelwe ngokukhethekile{3}}ekuklanyweni okuqandayo ukuze kugwenywe ukubanda kwamakhoyili nokuqhekeka. Okwesithathu, naka izinkomba zokonga ugesi: beka phambili imikhiqizo efakwe abalandeli abashintshashintshayo kanye nezigcwalisi{5}}ezisebenza kahle kakhulu, futhi uhlole izindleko zokusebenza zesikhathi eside{6}}ngokususela esilinganisweni saminyaka yonke sokusebenza kahle kwesizini (SEER). Okwesine, imboni yokufanisa{8}}izimfuneko ezithile: imboni yezemithi idinga ukukhetha izinto ezihlanzekile-zebanga nemiklamo evaliwe, imboni yamakhemikhali idinga ukumelana nokugqwala okuthuthukisiwe, futhi izikhungo zedatha zidinga ukugxila{10}}emsindweni ophansi nemisebenzi yokulawula ehlakaniphile. Ngaphezu kwalokho, kuyadingeka ukuhlola ngokucophelela izici ezifana nokutshalwa kwezimali kokuqala, izindleko zokunakekela, kanye nendawo yaphansi yezinto zokusebenza. Uma kunesidingo, idizayini ye-modular ingamukelwa ukuze ihlangabezane nezidingo zokunwetshwa kwamandla okukhiqiza esikhathini esizayo.
