Umehluko Oyinhloko Phakathi kwe-Counterflow Closed Cooling Towers kanye-ne-counterflow Cooling Towers
I-Counterflow ivale imibhoshongo yokupholisa futhi imibhoshongo yokupholisa{{0}i-counterflowziyizinhlobo ezimbili ezisetshenziswa kabanzi zemishini yokupholisa evaliwe emkhakheni wokupholisa wezimboni. Kukhona umehluko omkhulu phakathi kwabo ekwakhiweni kwesakhiwo, izimiso zokushintshanisa ukushisa, izici zokusebenza kanye nezimo zohlelo lokusebenza. Okulandelayo ukuhlaziya okuqhathanisayo kusuka kubukhulu obuyinhloko.
Mayelanaukwakheka kwesakhiwo kanye nesiqondiso sokugeleza kokushintshana kokushisa, isici esiyinhloko se-counterflow evaliwe yokupholisa umbhoshongo yi-ukugeleza okuphambenephakathi kwendawo yokupholisa nomoya. Ingaphakathi layo lifakwe amakhoyili okushintshanisa ukushisa ahlelwe ame mpo. Amanzi okupholisa azungeza phakathi kwamakhoyili, kuyilapho amanzi efafaza ngokulinganayo phezu kwekhoyili ukusuka phezulu ukuya phansi.
Umoya obandayo ungena nge-air inlet engaphansi kombhoshongo, udlulele phezulu ngamakhoyili kanye nongqimba lwamanzi afuthayo, futhi ekugcineni ukhiphe ukushisa kusuka phezulu kombhoshongo. Lo mklamo unweba indlela yokuxhumana phakathi komoya, isifutho samanzi namakhoyili. Ngokwesakhiwo, ngokuvamile ithatha{2}}uhlangothi olulodwa noma olukabili{3}}ukuthatha komoya oseceleni, okunomzimba wombhoshongo ophakeme kanye nendawo encane ephansi.
Umbhoshongo wokupholisa{{0}we-counterflow ophambanayo uhlanganisa izici zesakhiwo sakho kokubili counterflow kanye crossflow, futhi yaziwa nangokuthi "umbhoshongo wokupholisa-we-counterflow hybrid". Umzimba wombhoshongo uvame ukuhlukaniswa ube izingxenye ezingaphezulu nezingezansi.
Ingxenye engezansi yamukela isakhiwo sokugeleza kwe-crossflow, lapho umoya udlula khona ngokuvundlile phakathi kwamakhoyili ngokusebenzisa ama-air inlets aseceleni omzimba wombhoshongo; ingxenye engenhla iyisakhiwo esiphikisayo, lapho umoya ugeleza ubheke phezulu ngokuthintana okuphambene namanzi okufuthwa. Amakhoyili awo okushintshanisa ukushisa ahlukaniswe abe izingxenye ze-crossflow kanye ne-counterflow.
Amanzi afuthayo aqale ageleze phakathi kwamakhoyili e-counterflow engxenyeni engenhla bese ewela kumakhoyili awelayo engxenyeni engezansi. Umzimba wombhoshongo uwonke unobubanzi obukhudlwana nobude obuphansi uma kuqhathaniswa nombhoshongo wokugeleza ophikisayo wokucaciswa okufanayo.
Mayelanaukusebenza kahle kokushintshaniswa kokushisa nokusebenza kokusetshenziswa kwamandla, idizayini yeshaneli yokugeleza ephikisanayo yombhoshongo wokupholisa ovaliwe we-counterflow ithuthukisa kakhulu ukushisa nokusebenza kahle kokudlulisa okukhulu phakathi kwegesi noketshezi.
Umoya ungena usuka-endaweni enezinga lokushisa eliphansi, kancane kancane umunca ukushisa emanzini okufuthwayo namakhoyili, futhi izinga lokushisa lomoya ophumayo lisondele kunomkhawulo ophezulu wezinga lokushisa lamanzi afuthwayo, okuholela kumehluko omkhulu wokushintshana kokushisa.
Inezinzuzo ezisobala zokonga amandla uma uphatha-umthwalo wokushisa ophezulu. Kodwa-ke, ngenxa yokuthi ukugeleza komoya kufanele kunqobe amandla adonsela phansi amanzi okufuthwa kanye nokumelana nesigcwalisi, ifeni isebenza ngomfutho womoya ophakeme uma kuqhathaniswa, okuholela ekusetshenzisweni kwamandla okuphezulu kancane.
Ngokuthembela esakhiweni sayo esiyingxubevange secrossflow + counterflow,-umbhoshongo wokupholisa we-counterflow ufinyelela ibhalansi phakathi kokusebenza kahle kokushintshisana kokushisa nokusetshenziswa kwamandla. Isakhiwo se-crossflow esigabeni esiphansi sinokumelana nokugeleza komoya okuphansi, ngakho-ke ukusetshenziswa kwamandla kwabalandeli kuphansi kakhulu;
isakhiwo esiphikisayo esisesigabeni esingaphezulu sigcwalisa ukujula kokushintshana kokushisa, futhi ukusebenza kahle kwamandla sekukonke kuphakathi kwalokho kombhoshongo wokugeleza omsulwa kanye nombhoshongo ohlanzekile wokugeleza. Ngesikhathi esifanayo, amanzi afuthayo wesiphambano{1}}sombhoshongo wokugeleza we-counterflow asabalaliswa ngokulinganayo, angajwayelene nezinto zekhoyili eyomile, anciphisa ubungozi bokukalwa kwamakhoyili, futhi agcina ngokungaqondile{2}}ukushintshaniswa kokushisa kwesikhathi eside.
Kusukela ekuhlaziyeni kweizimo zohlelo lokusebenza nokuzinza kokusebenza, ngenxa yendawo yayo encane yaphansi kanye nokusebenza kahle kokushintshaniswa kokushisa okuphezulu, umbhoshongo wokupholisa ovaliwe ophikisanayo ufanelekile kakhuluizimo zokusebenza ezinendawo elinganiselwe kanye nomthwalo wokupholisa ophezulu, njengokupholisa-inqubo yezinga lokushisa eliphezulu ku-metallurgy, embonini yamakhemikhali, ama-compressor amakhulu omoya nezinye izinkambu. Nokho, inezidingo eziphezulu zekhwalithi yamanzi.
Uma amanzi okufutha equkethe ukungcola okuningi, kulula ukwenza isikali endaweni yekhoyili, okuthinta umphumela wokushintshanisa ukushisa. Ngaphezu kwalokho, kufanele kuqashelwe ukunqanda-iqhwa ngesikhathi sokusebenza kwasebusika ukuze kugwenywe ukunqwabelana kwamanzi kanye noqweqwe ngaphakathi kombhoshongo.
I-cross{0}counterflow cooling tower inezinzuzo zeukusebenza okuzinzile nokugcinwa okulula, futhi ifanele izimo ezinemithwalo yokupholisa eshintshashintshayo nezimo zekhwalithi zamanzi ezivamile, njengamasistimu omoya ophakathi nendawo kanye nokupholisa{0}} okokusebenza kwezimboni ezincane neziphakathi.
Amakhoyili esigaba se-crossflow angagcinwa ngaphandle kokungena emzimbeni wombhoshongo, ngakho-ke ubunzima bokulondoloza buphansi kunalowo we-counterflow tower; ngaphezu kwalokho, umzimba wombhoshongo unokuphakama okuphansi nokumelana nomoya ongcono, okwenza uzinze ekusebenzeni ezindaweni ezinomoya.
