Uyini Umehluko Phakathi Kwezinqaba Zokupholisa Ze-Cross-Flow Cooling and Counter-Flow Cooling Towers?

 

Ngokwephethini yokugeleza, ku-aikhawunta-umbhoshongo wokupholisa ogelezayo,Amanzi okupholisa awela aqonde phezulu ukusuka ohlelweni lokusatshalaliswa kwamanzi angaphezulu, kuyilapho umoya ugeleza ubheke phezulu usuka emazingeni omoya angaphansi kombhoshongo. Imidiya emibili ithintana ngezindlela eziphambene ngokuphelele, okuholela endleleni ende nenele ngokwanele yokushintsha ukushisa. Phakathi kucross-umbhoshongo wokupholisa ogelezayo, amanzi okupholisa nawo awela aqonde phezulu, kodwa umoya ungena ngokuvundlile usuka ezinhlangothini zombili zombhoshongo bese uthinta ukugeleza kwamanzi ngendlela enqamula mpo. Inqubo yokushintshanisa ukushisa ifana "nokushanela okuvundlile" ngaphezulu kokugcwalisa.

 

 

Ngokomklamo wesakhiwo, isistimu yokusabalalisa amanzi yesibali-sombhoshongo wokupholisa ogelezayo itholakala phezulu kombhoshongo, nesitsha sokuqoqa ngokuqondile ngaphansi kwesendlalelo sokugcwalisa. Asikho isidingo sokufaka ama-deflectors amanzi omoya we-cylinder ekhethekile, okwenza isakhiwo sihlangane futhi sithathe indawo encane yaphansi. Kodwa-ke, ukugcwaliswa kwayo kufanele kumelane nomthelela okabili wokugeleza kwamanzi nokugeleza komoya, okubeka izidingo eziphakeme kumandla wezinto ezibonakalayo. Isistimu yokusabalalisa amanzi yombhoshongo wokupholisa-okugeleza okuphambanayo iklanywe kakhulu njengohlobo lomkhombe oseceleni, nosendlalelo sokugcwalisa sihlelwe ekuthambekeni. Lo mklamo ubangela ukungezwani kokugeleza komoya okuphansi, futhi{6}}amafasitela amakhulu endawo angafakwa emaceleni ombhoshongo, okuphumelelisa ukusebenza kahle komoya okuphezulu. Noma kunjalo, ukuvimbela amaconsi amanzi ukuthi angaphumi ngokugeleza komoya ovundlile, izingqimba eziningi zeziphambukisi zamanzi kufanele zengezwe, okuholela ekuphakameni okuphelele kanye nendawo enkulu yaphansi.

 

 

 

Mayelana nokusebenza nezimo zohlelo lokusebenza, imibhoshongo yokupholisa-egelezayo inikezela ngokusebenza kahle kakhulu kokushintshisana kokushisa. Ngaphansi komthwalo ofanayo wokupholisa, banevolumu encane, futhi umehluko wokushisa wamanzi okupholisa ungafinyelela ku-5 ~ 10 degree. Zifanele izimo zezimboni ezinezidingo eziphezulu zokunemba kokupholisa kanye nesikhala sokufakwa esilinganiselwe, njengokucutshungulwa kwemishini okunembayo, amasistimu omoya ophakathi nendawo, namasethi amancane okuphehla ugesi. Imibhoshongo yokupholisa i-Cross-flow flow ifaka ukumelana komoya omncane kanye nokusetshenziswa kwamandla okuphansi kwabalandeli. Ukwengeza, ukugcwaliswa kwabo akujwayele ukuvala, futhi ukulungiswa nokuhlanza kulula kakhulu. Afanele amasistimu amanzi amakhulu okupholisa-agelezayo,{10}}aphakeme kakhulu, njengamasistimu okupholisa ajikelezayo ezitshalo zensimbi, izitshalo zamakhemikhali, nezitshalo ezinkulu zamandla ashisayo.

 

 

Ngaphezu kwalokho, kunomehluko ezindlekweni ze-O&M zalezi zinhlobo ezimbili. Abasabalalisi bamanzi bekhawunta-yemibhoshongo yokupholisa egelezayo bajwayele ukuvaleka futhi badinga ukuhlakazwa nokuhlanza njalo, futhi izindleko zokushintshwa kokugcwalisa ziphezulu uma kuqhathaniswa. Amafasitela asemaceleni afaka umoya kanye nokugcwaliswa kwemibhoshongo{3}}epholisa amanzi ephambanayo inganakekelwa ngokuqondile kusukela ngaphandle, okuholela ebunzimeni bokukhanda obuphansi futhi ibenze ifaneleke{4}}izimo zokusebenza eziqhubekayo zesikhathi eside.

 

 

Kafushane, lapho kukhethwa uhlobo, okubalulekile kufanele kunikezwe umthwalo wokupholisa, indawo yokufaka, izimo zekhwalithi yamanzi, kanye nezindleko ze-O&M:khetha isibali-uhlobo lokugeleza kwesikhala esincane-, nezidingo zokupholisa ezinemba okuphezulu{2}; khetha -uhlobo lokugeleza oluphambanayo ukuze uthole-ukugeleza okukhulu,{5}}okuphezulu{5}}nezimfuneko zokusetshenziswa{6}}zamandla aphansi{7}}.
