Izinyathelo Zokunqanda Ubusika-Zokuqandisa Izinyathelo Zokuvalwa-Izinqaba Zokupholisa Zesifunda

Njengoba kusondela amakhaza ashubisa umnkantsha, abangani abaningi enyakatho yeChina kungenzeka bahlangabezane nokuqhuma kwamapayipi okubangelwa amazinga okushisa aphansi. Yize iningi labaphathi besikhungo bejwayelene-nemibhoshongo yokupholisa amasekhethi evulekile, bazi okuncane mayelana-nemibhoshongo evaliwe. Imibhoshongo yokupholisa{4}evaliwe yesekethe ivamise ukusetshenziselwa okokusebenza okudinga{5}amanzi okupholisa ekhwalithi ephezulu. Lesi sihloko sigxile esakhiweni semibhoshongo epholile-yeziyingi ezipholile kanye nezinyathelo zayo zokulwa{8}}neqhwa ebusika.

Isingeniso se-Closed-Circuit Cooling Towers

Isimiso Sokusebenza

Umbhoshongo wokupholisa-ovaliwe wesekethe uhlanganisa izinhlelo ezimbili zokujikeleza kwamanzi: eyodwa ngeyamanzi afuthwayo angaphakathi (amanzi ompompi) nenye eyokuhlinzeka ngamanzi okupholisa (RO water) nokubuya.

Ipayipi elikhulu lokupholisa lamanzi okupholisa lingena embhoshongweni bese lihlukana libe amashubhu ethusi amaningi okushintshanisa ukushisa. Lawa mashubhu ahlelwe eduze nokupakishwa kombhoshongo, asuka phansi aye phezulu ngaphambi kokuba ahlangane epayipini elikhulu lokuphuma. Amanzi apholile athunyelwa emishinini yokushintshanisa ukushisa yangaphandle bese egaywa kabusha abuyiselwe embhoshongweni, enze iluphu yamanzi okupholisa evalwe ngokugcwele.

Amanzi okufutha angaphakathi asebenza njengohlelo oluvulekile olulekelelwa ngamanzi ompompi. Egcinwe ku-sump engaphansi, amanzi afuthwayo ampontshelwa kumsabalalisi wamanzi phezulu kokupakisha ngepompo yesifutho. Igelezela phansi, ifutha amashubhu amanzi okupakisha kanye nensimbi engagqwali ukuze kube lula ukushintshaniswa kokushisa okuphoqelekile phakathi kwamanzi afuthozayo namanzi apholisayo ngaphakathi kwamashubhu, ngaleyo ndlela kwehlise izinga lokushisa lamanzi okupholisa. Khonamanjalo, iqhutshwa isiphephetha-moya esiphezulu, ukuhwamuka kwamanzi kunciphisa izinga lokushisa lamanzi afuthwayo.

Izingxenye Ezibalulekile

Futha Iphampu: Inikeza amandla amanzi okufutha angaphakathi ukuze avumele ukugeleza okuya phansi kanye nokushintshaniswa kokushisa okuphoqelelwe ngamanzi okupholisa, ukwehlisa izinga lokushisa lamanzi okupholisa.

Umlandeli: Ifakwe okuguquguqukayo-i-frequency motor, ilawula izinga lokushisa lamanzi esifutho ngokulungisa imvamisa yabalandeli ukuze ilawule ukuhwamuka kwamanzi.

I-Heat Exchange Copper Tubes: Qinisekisa izinga eliphezulu lamanzi okupholisa kuyilapho uthuthukisa ukusebenza kahle kokudluliswa kokushisa ngamanzi afuthayo (enziwe ngezinto ezinokuguquguquka okuhle kakhulu kokushisa). Kodwa-ke, ukwakheka kwabo kuholela ekulahlekelweni kwengcindezi ephezulu.

Ukupakisha: Inweba isikhathi sokuthintana phakathi kwamanzi okufuthwa namashubhu ethusi, iphromotha ukushintshaniswa kokushisa okuphelele kakhulu.

I-Winter Anti-Izinyathelo Zokubanda Zokuvalwa-I-Circuit Cooling Towers

Sebenzisa Umthwalo Wakho Wokushisa Wetheminali Yephrojekthi

Lena indlela esebenza kahle kakhulu-ephikisana{1}}nendlela yokuqandisa esebenza kahle kakhulu. Ukushisa kwetheminali kukhuphula izinga lokushisa lamanzi okupholisa abuyisiwe. Uma amanzi abuyayo engena endaweni epholile-yeyiyingi epholile, ifeni ishayela ukushintshana kokushisa phakathi kwamashubhu ekhopha nomoya obandayo. Lokhu akwehlisi nje kuphela izinga lokushisa lamanzi kodwa futhi kuvimbela ukubanda embhoshongweni namapayipi angaphandle.

Sebenzisa ama-Antifreeze Agents

Ama-antifreeze agents ayinketho efanelekile yokuvimbela ukuqanda kwamapayipi futhi asetshenziswa kakhulu ezimbonini zezimoto, zikagesi, nezinye ezinemiphumela emihle kakhulu yokunqanda{0}}iqhwa.

Ama-Antifreeze Asemzimbeni: Nikeza ukusebenza okulula, okuphephile, nokuthembekile nokugcinwa.

Amasistimu okulawula ama-elekthronikhi: Bandakanya izici ezingalawuleki ezingaba khona, okuholela ekunakekeleni okungalungile kanye nezindleko eziphakeme.

Amanothi Okusebenza: Ngesikhathi sokusebenza kwasebusika, lungisa izinyathelo ngokuya ngezimo zezulu zangempela. Emazingeni okushisa aphezulu kakhulu noma kungazelelwe, uma umbhoshongo wokupholisa ungasetshenziswa, khipha amanzi ngokushesha kumakhoyili noma uwagcine egijima nomthwalo wokushisa ukuze ugcine ukugeleza kwamanzi ajikelezayo okwanele kanye nokudlulisa ukushisa{1}}ugweme ukuqhwa kwamanzi phakathi kwamakhoyili.

Umbono Oyiphutha Ovamile: Abanye o-opharetha bakholelwa ngephutha ukuthi ukunciphisa ukugeleza kwamanzi ukuze kwandiswe umehluko wezinga lokushisa kuvimbela ukubanda. Nokho, imibhoshongo{1}}evaliwe yokupholisa imibuthano iqukethe amakhoyili amaningi. Ukugeleza kwesistimu okuncishisiwe kubangela ukungalingani kwengcindezi, okuholela ekugelezeni kwamanzi kancane noma amile kwamanye amakhoyili, okuholela kalula emakhazeni kanye nokuqhuma kwamapayipi. Ngakho-ke, ngokufanelekile ukwandisa ukugeleza kwamanzi ajikelezayo ebusika ukuze uqinisekise ukuhamba kwamanzi kuwo wonke amaqembu amakhoyili.

Indlela Yokudonsa Ngempoqo

Lapho izinqaba zokupholisa zingadingeki ebusika, vula amavalvu okudonsa ikhoyili bese uvuthela umoya ocindezelwe kumakhoyili ukuze ukhiphe amanzi ngokuphelele ngaphambi kokuba izinga lokushisa lehle libe ngaphansi kuka-0 degree. Qaphela: Lawula umfutho womoya ocindezelwe phakathi kuka-0.3–1MPa. Ukucindezela okuphansi kakhulu kungase kushiye amanzi ayinsalela, kuyilapho ukucindezela okuphezulu kakhulu kungase kudlule umthamo wamakhoyili{5}wokuthwala.

Insulate Spray Pumps kanye Piping

Uma ukushintshana kokushisa phakathi komoya obandayo namashubhu ethusi (ngefeni egcwele imvamisa) kwehluleka ukuhlangabezana nezinga lokushisa elidingekayo lamanzi, faka amanzi afuthwe bese uqala iphampu yokufutha. Kodwa-ke, ukuguquguquka komthwalo kungase kubangele ukubanda kwamanzi okufuthwayo kanye nepompo. Ezimweni ezinjalo:

Faka i-insulate futhi ushise{0}}landelela amapayipi okufuthwa kanye nephampu, futhi ugcine iphampu yesifutho isebenza ukuze ulondoloze ukuhamba kwamanzi futhi uvimbele ukubanda.

Vimbela ukwakheka kweqhwa endaweni yokupakisha, engavimba ukungena komoya futhi kunciphise ukusebenza kahle kokukhipha ukushisa.

Noma, sebenzisa isistimu yokulawula ehlakaniphile: ifeni igijimela phambili isikhathi esimisiwe, ima, bese ihlehla isikhathi esimisiwe ukuze ivuthele umoya oshisayo embhoshongweni futhi incibilikise iqhwa.
