Ukuvikela Okuqandayo Kwezakhiwo Ezipholile Ezivaliwe-zeCircuit Cooling Towers

Njengoba kubanda kakhulu kusondela, abantu abaningi enyakatho yeChina cishe baye babhekana nokuqhuma kwamapayipi amanzi okubangelwa amazinga okushisa aphansi. Abaphathi abaningi bezikhungo zefekthri bajwayelene-nemibhoshongo yokupholisa eyiziyingi evulekile kodwa banolwazi oluncane ngale{2}}evaliwe. Imibhoshongo yokupholisa{4}evaliwe yesekethe ivamise ukusetshenziselwa okokusebenza okudinga{5}amanzi okupholisa ekhwalithi ephezulu. Lesi sihloko sichaza ngokuyinhloko ukwakheka kwemibhoshongo epholile-yeziyingi ezipholile kanye nezinyathelo zayo zokuvikela iqhwa ebusika!

Isingeniso se-Closed-Circuit Cooling Towers

Isimiso Sokusebenza

Umbhoshongo wokupholisa-ovaliwe wesekethe uhlanganisa izihibe ezimbili zokujikeleza kwamanzi: enye ingeyamanzi afuthowe angaphakathi (amanzi ompompi) kanye neyokuhambisa nokubuyiswa kwamanzi okupholisa (RO water). Ipayipi elikhulu lokungena kwamanzi lombhoshongo wokupholisa lingena embhoshongweni futhi lihlukanise libe amashubhu ethusi amaningi okushintshanisa ukushisa, ahlelwe eduze nokupakishwa kwangaphakathi. Amashubhu ethusi ahamba esuka phansi aye phezulu abese ehlangana epayipini elikhulu lokuphuma kwamanzi. Amanzi aphumayo angena ezintweni zangaphandle zokushintsha ukushisa ukuze asetshenziswe ngaphambi kokuthi{4}}aphinde angene embhoshongweni wokupholisa, enze umjikelezo wamanzi okupholisa ovalwe ngokugcwele. Uhlelo lwamanzi lwesifutho lwangaphakathi luvuliwe, lwengezwe ngamanzi ampompi. Ku-sump engaphansi kombhoshongo, iphampu yesifutho iletha amanzi kumsabalalisi ongaphezulu kwendawo yokupakisha, efafaza amanzi ehlele phansi kumashubhu ethusi okupakisha nawokupholisa. Amanzi afuthwayo athola ukushintshaniswa kokushisa okuphoqelekile ngamanzi okupholisa ukuze ehlise izinga lokushisa lamanzi okupholisa ngaphakathi kwamashubhu ethusi. Phakathi naleso sikhathi, ngaphansi kwesenzo se-fan ephezulu, izinga lokushisa lamanzi e-spray liyancishiswa ngokusebenzisa ukuhwamuka kwamanzi.

Izingxenye Ezibalulekile Zemibhoshongo Yokupholisa Yesifunda Evaliwe-

Iphampu Yesifutho: Inikeza amandla amanzi okufutha angaphakathi, iwavumela ukuthi ageleze aye phansi ukuze ashintshisane ngokuphoqeleka ukushisa namanzi okupholisa, ngaleyo ndlela ehlise izinga lokushisa lamanzi okupholisa.

Ifeni: Ifakwe okuguquguqukayo-injini yefrequency, ifeni ilawula izinga lokuhwamuka kwamanzi okufuthwa ngokulungisa ukuvama kwawo, ngaleyo ndlela ilawule izinga lokushisa lamanzi okufuthwa.

I-Heat Exchange Copper Tubes: Ngenkathi iqinisekisa ikhwalithi yamanzi okupholisa, lawa mashubhu athuthukisa ngempumelelo ukushintshanisa ukushisa phakathi kwamanzi okupholisa kanye namanzi afuthayo (ngenxa yokusetshenziswa kwezinto eziphezulu zokushisa ezishisayo). Kodwa-ke, ukulahlekelwa kwengcindezi kuphezulu kakhulu ngenxa yezidingo zesakhiwo.

Ukupakisha: Kwenyusa isikhathi sokuthintana phakathi kwamanzi okufuthwa namashubhu ethusi, kuqinisekisa ukushintshaniswa kokushisa okwanele.

Izinyathelo Zokuvikela Zokuqanda Ebusika Zemibhoshongo Evaliwe-yeCircuit Cooling Towers

I-Anti-Ukubanda Ngokusebenzisa Umthwalo Wokushisa Wokugcina Wephrojekthi ngokwayo

Lena indlela{0}}eyonga kakhulu amandla. Umthwalo wokugcina uphakamisa izinga lokushisa lamanzi okupholisa abuyisiwe. Uma amanzi abuyisiwe ethunyelwa-embhoshongweni wokupholisa wesekhethi evaliwe, ifeni yenza kube lula ukushintshanisa ukushisa phakathi kwamashubhu ethusi nomoya obandayo, ehlise izinga lokushisa lamanzi kuyilapho ivimbela ukubanda kombhoshongo wokupholisa namapayipi angaphandle.

I-Anti-I-Antifreeze Fluid

Uketshezi lwe-Antifreeze luyisinqumo esilungile sokuvikela izingozi zokuqandisa kwamapayipi. Isetshenziswa kakhulu ezimbonini zezimoto, zikagesi, nezinye, inikeza ukusebenza okuhle kakhulu kwe-antifreeze. Uketshezi lwe-antifreeze olubonakalayo lufanelekile, luphephile, futhi lunokwethenjelwa ukuze lusetshenziswe futhi lulungiswe.

Uhlelo lokulawula ugesi lunezici ezingalawuleki ezingaba khona, okwenza ukusebenza nokugcinwa kungabi lula kakhulu ngezindleko eziphakeme uma kuqhathaniswa. Ngesikhathi sokusebenza kwasebusika, kuyadingeka ukucabangela izimo zezulu zangempela. Uma isimo sezulu sishintsha kakhulu noma ngokuzumayo, imibhoshongo yokupholisa engasetshenziswanga kufanele ibe namanzi asemakhoyili akhishwe ngenkani kusenesikhathi noma ngesikhathi esifanele, noma isebenze ngomthwalo wokushisa ukuze kugcinwe ukugeleza kwamanzi ajikelezayo okwanele kanye nokujikeleza komthwalo wokushisa, ukuvimbela amanzi kumakhoyili ukuthi angabandi. Ukungaqondi kahle okuvamile phakathi kwama-opharetha ukuthi umehluko omncane wezinga lokushisa ubangela ukubanda, ngakho behlisa imvamisa yepompo ukuze banciphise ukugeleza futhi bakhulise umehluko wezinga lokushisa lokunqanda ukuqhwa. Kodwa-ke, imibhoshongo{4}}evaliwe yokupholisa isekethe iqukethe amaqembu amakhoyili amaningi. Lapho ukugeleza kwesistimu kuncipha, ukungalingani kwengcindezi phakathi kwamakhoyili kuholela ekugelezeni kancane noma ukungagelezi kwamanzi kwamanye amakhoyili, okungenzeka kakhulu kubangele ukubanda kanye nokuqhuma kwamapayipi. Ngakho-ke, lapho usebenzisa{7}}imibhoshongo evaliwe ebusika, ukugeleza kwamanzi ajikelezayo kufanele kukhuliswe ngokufanelekile ukuze kuqinisekiswe ukugeleza kwamanzi eqenjini ngalinye lamakhoyili.

Ukukhipha Okuphoqiwe Kokuvimbela-Ukubanda

Lapho kungekho sidingo semibhoshongo yokupholisa ebusika, ngaphambi kokuba izinga lokushisa lenze libe ngaphansi kuka-0℃, vula ivalve yokukhipha ikhoyili bese uphoqa umoya ocindezelwe ukuba ungene kumakhoyili ukuze ukhiphe wonke amanzi. Qaphela ukuthi ukucindezela komoya ocindezelwe akufanele kube phezulu kakhulu noma kube phansi kakhulu: kuphansi kakhulu kungase kuhluleke ukomisa amanzi kumakhoyili, kuyilapho ukuphakama kakhulu kungase kudlule umfutho{2}}umthamo wokuthwala wamakhoyili. Ibanga lengcindezi elilungile lingu-0.3-1MPa.

I-Thermal Insulation yamaphampu e-spray kanye namapayipi

Uma ukushintshaniswa kokushisa phakathi komoya obandayo namashubhu ethusi wamanzi okupholisa (ngefeni egijima kakhulu) engakwazi ukuhlangabezana nezinga lokushisa elidingekayo lamanzi, kuyadingeka ukwengeza amanzi okufutha bese uqalisa iphampu yokufutha. Kodwa-ke, ngenxa yokuguquguquka komthwalo, amanzi afuthwayo kanye nepompo kungase kube yiqhwa. Kulesi simo, ukufakwa kwe-thermal kanye nokulandela ukushisa kufanele kufakwe kumapayipi okufutha kanye nepompo. Qala iphampu yokufutha ukuze ugcine amanzi okufutha ezungeza, uvimbela ukubanda kwamapayipi nepompo. Ngaleso sikhathi, vimbela ukwakheka kweqhwa endaweni yokupakisha, okungase kuvimbele ukungena komoya futhi kuthinte ukuchithwa kokushisa. Noma, sebenzisa isistimu yokulawula ehlakaniphile lapho ifeni igijimela phambili isikhathi esimisiwe, ima, bese igijima ibuyela emuva imizuzu embalwa ngemva kokulibaziseka. Ukuzungezisa okuphambene kwefeni kuphephezela umoya oshisayo ngaphakathi kombhoshongo ngaphandle ukuze kuncibilike iqhwa.
