Ezinqubweni zezimboni ezisukela ekukhiqizweni kwamakhemikhali kuya ekuphathweni kwamanzi amdaka, ukulinganiswa koketshezi kubhekene nezinselele ezingapheli. Ama-asidi agqwalisayo, ama-slurry aqinile, kanye nama-slurry abrasive anezinhlayiya eziqinile sekuyisikhathi eside ehlola imikhawulo yamamitha okugeleza avamile, okuholela ekuqhekekeni okuvamile, ukufundwa okungalungile, kanye nesikhathi sokungasebenzi esibizayo. Ngokuphikisana nalokhu, amamitha okugeleza kagesi (ama-EMF) avele njengesixazululo esinamandla, esenzelwe ukunqoba izimo zoketshezi ezinzima kakhulu. Ngokungafani namamitha omshini awela ekugugeni, ekuvalekeni, noma ekuhlaselweni ngamakhemikhali, ama-EMF ayachuma lapho amanye ehluleka khona—okubonisa ukuthi akukho ketshezi olunzima kakhulu ukulilinganisa ngokunemba nangokuthembeka.
Ubuchwepheshe bendabuko bokulinganisa ukugeleza buhluleka ukuhambisana noketshezi oludingayo. Amamitha e-turbine, isibonelo, athembele kuma-blades ajikelezayo aguguleka kalula yizinhlayiya ezihuquzelayo noma agcwaliswe uketshezi oluqinile njenge-molasses noma i-sludge. Ama-orifice plates nama-Venturi tubes athambekele ekuvalekeni lapho kuphathwa ama-slurry, kuyilapho izingxenye zawo zensimbi ziguguleka ngokushesha uma zithintana namakhemikhali afana ne-hydrochloric acid noma i-sodium hydroxide. Lokhu kulinganiselwa kuhumusha ukunemba okuphazamisekile: imitha evalekile noma egugile ingaphambuka ngo-10% noma ngaphezulu kusuka emazingeni okugeleza angempela, okuholela ekulinganisweni okungalungile ezinqubweni zamakhemikhali, ukukhokhisa ngokweqile ekuthuthweni koketshezi, noma ukungalandeli imithethonqubo yemvelo. Ezimbonini lapho izakhiwo zoketshezi zishintsha khona—njengokucubungula ukudla, lapho i-viscosity ishintsha khona ngokushisa—amamitha endabuko anikeza ukuguquguquka okuncane, adinga ukulinganiswa kabusha njalo noma ukushintshwa.
Amamitha okugeleza kagesi anqoba lezi zinselele ngomklamo ohlukile ngokuphelele: alinganisa ukugeleza ngaphandle kokuthintana ngqo nezingxenye ezihambayo, esebenzisa uMthetho kaFaraday Wokungenisa Amandla kagesi. Nansi indlela esebenza ngayo: ipayipi lemitha lifakwe izinto ezingamelana namakhemikhali (njenge-PTFE, irabha, noma i-ceramic), kuyilapho ama-electrode amabili afakwe ngaphakathi kwendwangu ekhiqiza insimu yamagnetic kulo lonke uketshezi. Njengoba uketshezi oluqhubayo lugeleza ensimini, lubangela i-voltage kagesi ehambisana nejubane layo—leli voltage lilinganiswa ngama-electrode futhi liguqulwa libe idatha yesilinganiso sokugeleza. Ukungabikho kwezingxenye ezihambayo kuqeda ukuguguleka okuvela ezintweni ezisusayo kanye nokuvaleka koketshezi oluqinile, kuyilapho ulwelwesi olungeyona insimbi lusebenza njengesivikelo ezintweni ezibolayo. Lo mklamo uqinisekisa ukuthi ama-EMF ahlala eqinile futhi enembile ngisho nalapho ephatha uketshezi oluzobhubhisa amamitha endabuko.
Okwenza ama-EMF aguquguquke ngempela yikhono lawo lokuzivumelanisa nezici zoketshezi eziyingozi kakhulu. Ngoketshezi oluqothulayo—kusukela kuma-acid ezimboni nama-alkali kuya emanzini olwandle kanye nezinyibilikisi zamakhemikhali—izinto zolwelwesi lwemitha zingenziwa ngokwezifiso ukuze zivumelane nohlelo lokusebenza. Izindwangu ze-PTFE zimelana namakhemikhali amaningi emvelo namakhemikhali angaphili, okwenza zibe zilungele izinqubo zemithi noma ze-petrochemical, kuyilapho izindwangu zerabha ziphumelela kakhulu ekuphatheni udaka oluqothulayo olunezinhlayiya ezinkulu, njengemigodi yemigodi noma amanzi angcolile ane-sediment. Uketshezi oluqinile, okuhlanganisa izinamathiselo, izinto zokugcoba, kanye nemikhiqizo yokudla efana noshokoledi noma isiraphu, lugeleza kahle ngepayipi elingavimbelwe le-EMF, ngaphandle kwezindlela ezincane ezibangela ukwakheka. Ngisho noketshezi oluqothulayo oluqukethe isihlabathi, amatshe ayigugu, noma izingcezu zensimbi ludlula ngaphandle kokulimaza imitha, njengoba kungekho zingxenye ezijikelezayo ezizoguga. Lokhu kuvumelana nezimo kusho ukuthi i-EMF eyodwa ingaphatha izinhlobo eziningi zoketshezi kuzo zonke izigaba zenqubo ezahlukene, kunciphisa isidingo samamitha akhethekile.
Ngale kokuqina, ama-EMF aletha ukunemba okubalulekile ezicelweni ezibalulekile. Agcina ukunemba ngaphakathi kuka-±0.5% wesilinganiso esigcwele (futhi ngokuvamile kungcono) ebangeni elibanzi lokugeleza, kusukela esivinini esiphansi (esiphansi njengo-0.01 m/s) kuya emazingeni aphezulu okugeleza afanele amapayipi ezimboni. Lokhu kunemba kubalulekile ekucubungulweni kwamakhemikhali, lapho ukukala okunembile kwezinto zokusetshenziswa kuqinisekisa ikhwalithi nokuphepha komkhiqizo, kanye nokwelashwa kwamanzi amdaka, lapho idatha yokugeleza enembile isekela ukuhambisana nemikhawulo yokukhipha. Ama-EMF aphinde avelele ekulinganiseni uketshezi olungenawo ugesi ofanayo, njenge-slurry enokuqukethwe okuqinile okuhlukahlukene, okudida amamitha endabuko. Ikhono lawo lokunikeza idatha ehambisanayo nethembekile ngisho nasezimweni zoketshezi ezingazinzile kuwenza abe yinto ebalulekile ezimbonini lapho ukulawulwa kwenqubo kubaluleke kakhulu khona.
Izinzuzo ezingokoqobo zama-EMF zidlulela ekusebenzeni kahle kanye nokonga izindleko. Njengoba zingenazo izingxenye ezinyakazayo zokunakekelwa noma zokushintsha, zidinga ukunakekelwa okuncane—ngokuvamile ukulinganiswa okuvamile njalo eminyakeni eyi-1-3, uma kuqhathaniswa nokulungiswa kwekota yamamitha omshini. Lokhu kunciphisa isikhathi sokungasebenzi kanye nezindleko zokulungisa, ikakhulukazi ezindaweni okunzima ukuzifinyelela njengemipayipi engaphansi komhlaba noma izilungiselelo zezimboni ezishisa kakhulu. Ama-EMF nawo kulula ukuwafaka, anezinketho ze-flange, i-wafer, noma ukufakwa okuhambisana namapayipi akhona ngaphandle kokuguqulwa okukhulu. Ama-EMF amaningi anamuhla ahlanganisa ukuxhumana kwe-IoT, okuvumela ukuqapha kwangempela amazinga okugeleza, izexwayiso zokuxilonga ukuguguleka kwe-lining noma i-electrode fouling, kanye nokulinganiswa okukude. Lokhu kuhlakanipha kwedijithali kwenza ukulungiswa okusebenzayo, kuvimbele ukwehluleka okungalindelekile futhi kuqinisekise ukusebenza okuqhubekayo.
Kusukela ezimayini, uwoyela negesi kuya ekucutshungulweni kokudla kanye nemithi, ama-EMF abe yisinqumo esithandwayo sezimboni ezilwa noketshezi oluqinile. Ezitshalweni zamakhemikhali, alinganisa ama-reagent aqothulayo ngokunemba okuqondile, aqinisekisa ukusabela okuphephile nokusebenza kahle. Ezindaweni zokwelashwa kwamanzi amdaka, aphatha udaka oluqothulayo kanye nezinto zokuhlanza eziqothulayo, ahlinzeka ngemininingwane yokuthuthukisa izinqubo zokwelashwa. Embonini yokudla neziphuzo, alinganisa imikhiqizo eqinile njengoju noma utamatisi ngaphandle kokungcolisa uketshezi noma ukunambitheka okulimazayo. Ngisho nasezindaweni ezimbi kakhulu—njengemipayipi yokucindezela okuphezulu noma izinhlelo zokusebenza ze-cryogenic—ama-EMF ahlinzeka ngokusebenza okuqhubekayo, efakazela ukuguquguquka kwawo kuyo yonke imikhakha.
Njengoba izinqubo zezimboni zikhula zibe yinkimbinkimbi futhi izinselele zoketshezi ziba zimbi kakhulu, isidingo sokulinganisa ukugeleza okuthembekile nokuguquguqukayo sizokhula kuphela. Amamitha okugeleza kagesi avelele njengesixazululo esingagcini nje ngokulinganisa uketshezi—siyawanqoba. Ngokuphatha uketshezi oluqothulayo, oluqinile, nolukhuhlayo kalula, aqeda ukuhwebelana phakathi kokuqina nokunemba okuhlupha amamitha avamile. Kumabhizinisi, lokhu kusho ukunciphisa izindleko, ukulawulwa kwenqubo okuthuthukisiwe, kanye nokuthula kwengqondo ngokwazi ukuthi ukulinganisa kwawo ukugeleza kufanelana nanoma iyiphi inselele.
Ezweni lapho uketshezi luyigazi lokuphila kwemboni, amamitha okugeleza kagesi angamaqhawe angadumile agcina izinqubo zihamba kahle. Afakazela ukuthi kungakhathaliseki ukuthi uketshezi lunzima kangakanani, ukulinganisa ngokunemba akugcini nje ngokuba yinto engenzeka—kuyasebenza. Njengoba ubuchwepheshe buthuthuka, ama-EMF azoqhubeka nokukhula, enikeza ukuqina okukhulu nobuhlakani. Kodwa okwamanje, ahlala eyindinganiso yegolide yokusingatha uketshezi oludinga kakhulu, echaza kabusha lokho okungenzeka ekulinganisweni kokugeleza kwezimboni.
