Uma uzwa ‘ukusimama’ emgqeni wethu womsebenzi, umcabango osheshayo uvame ukugxumela kumaphaneli elanga noma kuma-wind turbines. Kodwa ezimbonini ezisindayo—izitshalo zamakhemikhali, izindawo ezihluzwayo, uhlobo lwamandla—kunesiqephu sekhithi ebesilokhu siphakamisa amashumi eminyaka buthule: isishintshi sokushisa esipholile emoyeni (ACHE). Ngibone izethulo eziningi kakhulu lapho kucwebezeliswe khona njengokuthi nje ‘inqwaba ye-fan and fin tube bundle,’ egeja yonke iphuzu. Indaba yangempela ayikho emsebenzini wayo oyisisekelo; kuyindlela ifilosofi yayo yokuklama engokwemvelo inqamula ngayo uhlamvu lokupholisa olusebenzisa izinsiza. Ayidingi amanzi amaningi ukuze isebenze. Lelo qiniso elilodwa lishintsha ukubala kokusimama ngokuphelele, ikakhulukazi ezindaweni ezingenawo amanzi. Kodwa akuyona inhlamvu yomlingo. Ngike ngaba kumasayithi lapho iyunithi engacaciswanga kahle noma enakekelwa kahle iba ingulube yamandla, ibukela phansi ngokuphelele ukucabanga kwayo kwemvelo. Ngakho-ke, bakuthuthukisa kanjani ukusimama kweqiniso? Kuyinhlanganisela yomthelela oqondile kanye nezinzuzo ezicashile, zesistimu owazisa kuphela ngemva kokuzibona ensimini, kukho kokubili impumelelo nokwehluleka okukhungathekisayo.
I-Equation Yamanzi: Ngaphezu Kokongiwa Nje
Isiqalo esisobala kakhulu ukusetshenziswa kwamanzi. Igobolondo lendabuko kanye nezishintshisi zokushisa zamashubhu zithembele ekugelezeni okuqhubekayo kwamanzi okupholisa, ngokuvamile asuka emfuleni, echibini, noma eseketheni enkulu yokupholisa. Lokho kusho ukuhoxiswa kwamanzi, amakhemikhali okwelapha ukuvimbela ukukala nokungcoliswa kwemvelo, kanye nokuphuma okushisayo kubuyele emthonjeni. I-ACHE iqeda yonke leyo logi. Ngikhumbula iphrojekthi endaweni ethandwa isomiso yaseTexas yesikhungo sokukhiqiza igesi. Umklamo wokuqala weklayenti wawufuna uhlelo lokupholisa olumanzi, kodwa imvume yokudonsa amanzi kwakuyiphupho elibi. Sivotele i-cooler bank yabalandeli. Izindleko zangaphambili zaziphezulu, kodwa inkululeko yokusebenza yayisheshayo. Akusekho ukuxoxisana ngamalungelo amanzi, akukho mingcele yokushisa yokuqapha yokukhishwa. Ukuphumelela kokusimama lapha kuphelele: kunciphisa indawo yezimboni ku-hydrology yasendaweni icishe ibe yiqanda. Okomkhiqizi ofana I-Shanghai SHENGLIN M&E Technology Co., Ltd, iphothifoliyo yakhe iku https://www.shenglincoolers.com yakhelwe eduze kwalobu buchwepheshe, lesi isiphakamiso senani eliwumongo abasisungulela—ukunikeza ukupholisa kwezimboni okuvimbela inkinga yamanzi ngokuphelele.
Kodwa-ke, isimangalo 'samanzi ayiziro' sidinga ukufaneleka okuncane. Ungase ube nesistimu encane yokugeza amanzi yokuhlanza amashubhu amaphiko uma umoya ungcole kakhulu, kodwa lokho kuphakathi nendawo kanye nengxenye encane yalokho okusetshenziswa umbhoshongo wokupholisa. I-nuance yangempela yokusebenza ibhekene nokusebenza okomile. Lapho ususa amanzi amaningi ashisayo, usala nomthamo wokushisa ompofu womoya. Lokhu kuphoqa uhlobo oluhlukile lokucabanga kwedizayini—ukukhulisa indawo engaphezulu ngamaphiko, kuthuthukisa ukugeleza komoya. Kuwukuhwebelana okuphusha ukusebenza kahle kwamandla kwabalandeli ukuya phambili, okuholela kungqimba olulandelayo, olungacacile lokusimama.
Amandla kanye Nenkinga yabalandeli
Yilapho inkulumo iba muncu. Abagxeki baveza kahle ukuthi ukugijima kwabalandeli abakhulu kudla ugesi obalulekile. Ngike ngadlula amayunithi lapho umsindo wabalandeli uvala izindlebe, uphawu oluqinisekile lwesistimu engasebenzi kahle noma osebenza kanzima kakhulu ngenxa yamashubhu awonakele. Isixhumanisi sokusimama sisemininingwaneni yokuthi uphatha kanjani lokho kufakwa kwamandla. Ekuqaleni komsebenzi wami, sasibalula abalandeli besivinini esimisiwe yonke indawo. Ilula, iqinile. Kodwa-ke usemseni wezinga lokushisa lomoya elizungezile. Ekuseni okupholile, ubanda kakhulu futhi uchitha amandla abalandeli; ntambama eshisayo, inqubo ingase ikhubeke ngoba awukwazi ukuphusha umoya owengeziwe. Lokho akuwona umsebenzi oqhubekayo.
Ukushintshela kuma-variable frequency drives (VFDs) kuma-fan motors kwakuwukushintsha umdlalo. Manje, isivinini sabalandeli siyashintsha ngokuya ngezinga lokushisa eliphumayo lenqubo noma izimo ze-ambient. Ukudonswa kwamandla kwefeni kuhambisana nekhyubhu yejubane layo. Yehlisa isivinini ngo-20%, futhi ucishe wehlise ngohhafu ukusetshenziswa kwamandla. Ngike ngabona amaphrojekthi e-retrofit lapho ukungeza ama-VFD akhokhwa eminyakeni engaphansi kwemibili kuphela ekongeni ugesi. Lokhu kuyinzuzo esebenzayo, eqhubekayo eshintsha i-ACHE isuke ekubeni ingxenye yesenzo sokwenziwa ibe yinto eyenziwe ngokugcwele. Abakhiqizi babambe iqhaza, baklama ama-fan blade alula, ama-aerodynamic kakhudlwana nama-gearbox asebenza kahle kakhulu ukuze bakhiphe wonke amaphesenti okusebenza kahle.
Kukhona futhi ukonga amandla okungaqondile okuvame ukunganakwa: akukho ukupompa amanzi. Uhlelo olukhulu lwamanzi okupholisa ludinga amaphampu amakhulu ukuze ajikeleze izinkulungwane zamalitha ngomzuzu. Lokho kuwumthwalo ongashintshi, omkhulu kagesi ongekho nje ngesistimu yokupholisa umoya. Uma wenza ibhalansi egcwele yensiza yezitshalo, isithombe samandla esiphelele se-ACHE singaba sivuna ngokumangalisayo, ikakhulukazi ezifundeni ezinesimo sezulu esimaphakathi.
I-Material Longevity kanye ne-Lifecycle Thinking
Ukusimama akukhona nje okokufaka kokusebenza; imayelana nomjikelezo wempilo wehadiwe. I-ACHE eyakhiwe kahle iyingqalasizinda enonya. I-core bundle-amashubhu afakwe ohlakeni lwensimbi ye-carbon-ingahlala iminyaka engu-25-30 ngokunakekelwa okuyisisekelo. Ngiye ngahlola amayunithi kusukela ngeminyaka yawo-80s asasebenza ngenxa yokuthi indawo engaphakathi kwamashubhu (uhlangothi lwenqubo) iyalawulwa, futhi amaphiko angaphandle, kuyilapho ethonywa ukugqwala, ngokuvamile enziwa ngensimbi e-aluminium noma ezinye izimbobo zokuzivikela. Lokhu kuphila isikhathi eside kugwema imijikelezo evamisile yokushintshaniswa kanye nokukhishwa kokukhiqizwa okuhlobene kwezinto zokusebenza ezihlala isikhathi eside.
Izindlela zokwehluleka ziyafundisa. Ukuvuza kwamashubhu kwenzeka, ngokuvamile kubhondi ye-fin-to-tube noma lapho amashubhu egingqika ebhokisini likanhlokweni. Ukulungisa kwenziwa okwasendaweni—uxhuma ishubhu noma ushintsha ingxenye. Qhathanisa lokho nokushintshisana kwegobolondo neshubhu lapho ukuvuza okukhulu kungase kusho ukudonsa yonke inyanda, umsebenzi omkhulu. Ukulungiseka kwandisa impilo yempahla ngokuphawulekayo. Sake saba nenqwaba elinyazwe ukushwibeka kwe-crane esizeni. Esikhundleni sokuyichitha, ithimba elivela kumkhiqizi, njengalokho ongakulindela enkampanini enolwazi efana ne-SHENGLIN, lihlongoze ukusika indawo eyonakele kanye nokushisela kumojula entsha. Iyunithi ibibuyile ku-inthanethi emavikini, hhayi izinyanga. Lokho ukuphathwa kwempahla okuzinzile.
Nokho, ukukhetha impahla kubalulekile. Ezindaweni ezisogwini, isifutho sikasawoti singadla ngamafreyimu ensimbi ye-carbon. Ngiye ngabona amaphrojekthi lapho ukucacisa i-hot-dip galvanizing kusukela ekuqaleni kwengeza u-15% ezindlekweni kodwa kuphindwe kabili impilo yesevisi elindelekile. Lokho kutshalwa kwezimali kwangaphambili kuyisinqumo esiqondile sokusimama, esinciphisa ukumoshwa kwesikhathi eside kanye nokusetshenziswa kwezinsiza zokwakha kabusha.
Ukuhlanganiswa Kwesistimu kanye Nokubuyiselwa Kokushisa Kwemfucuza
Nansi i-engeli ethuthuke kakhudlwana: ukusebenzisa ama-ACHE hhayi nje njengesiphetho sokwenqaba ukushisa, kodwa njengento elawulekayo esikimini sokuthola ukushisa okulahliwe. Kuzwakala kungenangqondo—kungani ungafuna ukwenqaba ukushisa ngendlela ephumelela kakhudlwana? Okubalulekile ukulawula izinga lokushisa. Ake sithi unenqubo yokusakaza enokushisa kukadoti okusezingeni eliphansi kakhulu ukusebenzisa i-steam turbine, kodwa ungayisebenzisela ukushisisa amanzi okuphakelayo kusengaphambili noma ukushisa kwebhilidi. Uma okuwukuphela kwesipholile sakho kuyi-ACHE engahluziwe, enkulu kakhulu, ilahla konke lokho kushisa emkhathini ngaphambi kokuthi ukusebenzise.
Imiklamo yesimanje ivumela ukuba yinkimbinkimbi okwengeziwe. Ngokuhlukanisa inqwaba ibe yizigaba (okuvame ukubizwa ngokuthi amatheku) nokulawula abalandeli ngokuzimela, ungakwazi ukulawula ngokunembile izinga lokushisa lokuphumayo. Ungakwazi ukupholisa ukusakaza ngokwanele ukuze uhlangabezane nezidingo zenqubo, bese udlulisela ukusakaza okusafudumele uye kuluphu yesibili yokutakula. Ngaba nengxenye emsebenzini wokuhlola embonini kasimende lapho senza khona kanye lokhu. Sisebenzise i-ACHE eguquliwe ukuze sigcine izinga lokushisa elilungile leyunithi yomjikelezo we-organic Rankine (ORC) engezansi ekhiqize amandla asizayo. I-ACHE bekungeyona inkanyezi yombukiso, kodwa ukulawula kwayo okunembayo kwenza yonke loop yokutakula yasebenza. Lokhu kuliguqula lisuke ethuluzini lokusimama ngokukhipha (ukonga amanzi) liye kwelinye ngokunika amandla (ukwenza lula ukutholwa kwamandla).
Lokhu kudinga izinga eliphezulu lokucabanga komklamo wesistimu. Akukhona nje ukuthenga into epholile ngaphandle kweshalofu; ukuyihlanganisa nezilawuli namanye amayunithi enqubo. Lapho isebenza, i-synergy ikhulisa kakhulu ukusebenza kahle kwesitshalo okushisayo.
Izinselelo ze-Pragmatic kanye nokuhwebelana
Ukubhala ngalokhu ngaphandle kokukhuluma ngekhanda elibuhlungu kungaba ukungathembeki. Ukupholisa umoya akuhlali kuyimpendulo efanele. Okukhulu izinga lokushisa lomoya we-ambient. Ngosuku olungu-45°C (113°F) eMpumalanga Ephakathi, i-delta T epholile incipha kakhulu. Udinga indawo engaphezulu kakhulu, okusho ukuthi impahla eyengeziwe (ikhabhoni efakwe ngaphezulu), indawo yesakhiwo esiningi, namafeni amakhulu. Kwesinye isikhathi, isistimu exubile (emanzi/eyomile) iyindlela enhle eqhubekayo, isebenzisa ingxenye encane ehwamukayo ukupholisa indawo engenisa umoya ngezinsuku ezishisa kakhulu, inqamula umkhondo. Ngike ngabona amaphrojekthi lapho ukugcizelela kusistimu eyomile engu-100% ngenxa yezizathu zombono kwaholela esilwaneni esikhulukazi, esingasebenzi kahle esasibi kakhulu ekuhloleni okugcwele komjikelezo wempilo kunomklamo we-hybrid ohlakaniphile.
Enye inkinga yomhlaba wangempela ukungcoliswa kwe-air-side. Endaweni enothuli noma eduze kwesitshalo sikamanyolo, izimpiko ziyavaleka ngokushesha. Ukugeleza komoya kuyehla, amathangi okusebenza, namandla efeni ayakhuphuka. Udinga isu lokuhlanza elisebenzayo—ngokuvamile amasistimu okuhlanza aku-inthanethi azenzakalelayo anamabhomu ajikelezayo. Uma ukudebeselela lokhu, izinzuzo zokusimama ziyahwamuka njengoba iyunithi idonsa amandla okuphusha umoya ku-matrix evalekile. Kuyinkinga yesiko lokunakekela njengelobunjiniyela.
Ngakho-ke, ingabe zithuthukisa ukusimama? Nakanjani, kodwa ngokwemibandela. Banikeza indlela eqinile yokuqeda ukupholisa kwezimboni kusuka ekucindezelekeni kwamanzi futhi banikeze ukonga okujulile kwamandla ngokulawula okuhlakaniphile. Ukuqina kwazo kunciphisa ukumosheka komjikelezo wempilo. Kodwa ukuthuthukiswa akuzenzeki. Ivela ekucacisweni okucatshangelwayo—usayizi olungile, ukukhetha izinto, isu lokulawula abalandeli—kanye nokugcinwa kokusebenza okuzibophezele. Ezandleni zomqhubi onolwazi futhi esekelwe ubunjiniyela obuqinile obuvela kochwepheshe, isishintshi sokushisa esipholile emoyeni siba ngaphezu nje kocezu lwamapayipi anamaphiko; kuyingxenye eyisisekelo yokwakha imboni yezimboni eqinile, eqaphela izinsiza. Lokho kuyiqiniso elingokoqobo, elikude kakhulu nenkulumo yencwajana ecwebezelayo.
