Umtshintshi wobushushu oScraped Surface: Umgaqo, ukusetyenziswa kunye nophuhliso lwexesha elizayo

Isixhobo sokutshintshiselana ubushushu esikrwelwe ngumphezulu luhlobo lwezixhobo zokutshintshiselana ubushushu ezisebenzayo, ezidlala indima ebalulekileyo kushishino lokutya, iikhemikhali, amayeza kunye nezinye izimboni. Ngolwakhiwo olukhethekileyo loomatshini kunye nendlela yokusebenza, olu hlobo lwesixhobo sokutshintshiselana ubushushu lusombulula ingxaki yesixhobo sokutshintshiselana ubushushu sendabuko ekubhekaneni nokuxinana okuphezulu kunye nezinto ezilula ukuzilinganisa. Eli phepha liza kuhlalutya ngokupheleleyo isixhobo sokutshintshiselana ubushushu esikrwelwe, isixhobo esibalulekileyo semizi-mveliso, ukusuka kwimiba yomgaqo wokusebenza, iimpawu zesakhiwo, amasimi okusetyenziswa kunye neendlela zophuhliso zexesha elizayo.

 Okokuqala, umgaqo wokusebenza kunye nolwakhiwo lwesitshintshi sobushushu bomphezulu okhuhliweyo

Umgaqo oyintloko wokusebenza kwesitshintshi sobushushu esikrwelwe kukukrwela rhoqo umphezulu wotshintshiselwano lobushushu ngokujikelezisa isikrwela ukuze kufezekiswe ukudluliselwa kobushushu okusebenzayo. Ulwakhiwo olusisiseko luquka umzimba wesitshintshi sobushushu esisilinda, umngxuma ojikelezayo, indibano yesikrwela, isixhobo sokuqhuba kunye nenkqubo yokutywina. Umzimba wesitshintshi sobushushu uhlala unesakhiwo esiphindwe kabini, kwaye indawo yokufudumeza okanye yokupholisa idluliselwa embindini. Umngxuma ojikelezayo uxhotyiswe ngeeskra ezininzi, ezikufutshane nodonga lwangaphakathi lwesilinda phantsi kwesenzo samandla e-centrifugal kwaye zihlala zikrwela umphezulu wotshintshiselwano lobushushu ngokujikelezisa umngxuma.

 Ngexesha lokusebenza, izinto eziza kucocwa zingena kwi-heat exchanger ukusuka kwinxalenye ephezulu kwaye zigeleza phantsi kodonga lwangaphakathi lwesilinda phantsi kwesenzo somxhuzulane. I-rotary scraper ayidlali nje kuphela indima yokuxuba, kodwa okubaluleke ngakumbi, ihlaziya rhoqo ifilimu yezinto ezikumphezulu wokudlulisa ubushushu ukuthintela ukuba izinto zingabi shushu okanye zinyuke kumphezulu wobushushu obuphezulu. Le ndlela yokuvuselela ifilimu enamandla ivumela ii-scrape heat exchangers ukuba zifikelele ekusebenzeni kakuhle kokudlulisa ubushushu obuphezulu, ngokufuthi ukuya kuthi ga kwi-3-5 yee-heat exchangers eziqhelekileyo.

 Icandelo eliphambili lesitshintshi sobushushu esikrwelwe ngumphezulu yinkqubo yesikrwelwe, uyilo lwayo luchaphazela ngqo ukusebenza kwezixhobo. Izitshintshi zobushushu zomphezulu ezikrwelwe zanamhlanje zisebenzisa isikrwelwe esihlengahlengiswayo, ngokusebenzisa amandla entwasahlobo okanye e-centrifugal ukulungisa uxinzelelo loqhagamshelwano phakathi kwesikrwelwe kunye nodonga lwesilinda, kungekuphela nje ukuqinisekisa isiphumo esihle sokukrwelwa, kodwa nokuphepha ukuguguleka okugqithisileyo. Inkqubo yokutywina ikwayinxalenye ebalulekileyo, kokubini ukuthintela ukuvuza kwezinto, kodwa nokuqinisekisa ukusebenza kakuhle komngxuma ojikelezayo.

 

Okwesibini, iingenelo zobugcisa kunye nemida yesixhobo sokufudumeza umphezulu okhuhliweyo

Eyona nzuzo ibalulekileyo yesixhobo sokutshintsha ubushushu esikrazulayo kukukwazi kwaso ukuphatha izinto ezixineneyo nezinoburhabaxa kakhulu. Kwicandelo lokulungisa ukutya, njengokuvelisa i-puff pastry margarine, itshokholethi, ijam, itshizi kunye nezinye iimveliso, isixhobo sokutshintsha ubushushu sendabuko kunzima ukuhlangabezana neemfuno zenkqubo, kwaye isixhobo sokutshintsha ubushushu esikrazulayo sinokuzisombulula ngokugqibeleleyo ezi ngxaki. I-coefficient yayo yokudlulisa ubushushu inokufikelela kwi-2000-5000W/(m²·K), iphezulu kakhulu kunesixhobo sokutshintsha ubushushu seqokobhe kunye netyhubhu esiqhelekileyo.

 

Xa kusetyenzwa ngezinto ezilula ukuzilinganisa, iingenelo ze-scraper heat exchanger zicacile ngakumbi. Kwishishini le-petrochemical, ioyile enzima, i-asphalt kunye nezinye izinto kulula ukuzicola kumphezulu wokudlulisa ubushushu ngexesha lenkqubo yokufudumeza, kwaye ii-heat exchangers zendabuko zifuna ixesha lokuphumla rhoqo ukuze zicoceke. I-scraper heat exchanger ngokusebenzisa isiphumo sokucola esiqhubekayo, ithintela ngempumelelo isiganeko sokucola, yandisa kakhulu ixesha lokusebenza eliqhubekayo.

 

Nangona kunjalo, izixhobo zokutshintshiselana ubushushu ezikhutshiweyo nazo zinemida ethile. Eyokuqala yindleko ephezulu yezixhobo, ngenxa yesakhiwo sazo esintsonkothileyo soomatshini kunye neemfuno zokucubungula ngokuchanekileyo, utyalo-mali lokuqala lukhulu kakhulu kunezixhobo zokutshintshiselana ubushushu eziqhelekileyo. Okwesibini, iindleko zokugcina ziphezulu, kwaye isixhobo sokukhuhla kunye nesitywini zizinto ezibuthathaka kwaye kufuneka zitshintshwe rhoqo. Ukongeza, xa kusetyenzwa ngezinto ezinobungqingqwa obuphantsi, izibonelelo zazo azibonakali, kodwa zinokunyusa ukusetyenziswa kwamandla ngenxa yokuxubana koomatshini.

 

Okwesithathu, intsimi yesicelo kunye nophuhliso lwexesha elizayo lwesitshintshi sobushushu esikhuhliweyo

Kwishishini lokutya, izixhobo zokutshintshiselana ubushushu obuphezulu ezikhutshiweyo zisetyenziswa kakhulu ekuthambiseni itshokolethi, ekubulaleni i-jam, ekunyibilikiseni ibhotolo nakwezinye iinkqubo. Umzekelo, ekuvelisweni kwetshokolethi, izinto kufuneka zilawulwe ngokuchanekileyo kuluhlu oluthile lobushushu ukuze kulawulwe ubushushu, kwaye isixhobo sokutshintshiselana ubushushu esikhutshiweyo sinokufikelela kulawulo lobushushu oluchanekileyo kunye nokutshintshiselana kobushushu okufanayo ukuqinisekisa umgangatho wemveliso.

 

Kwicandelo leekhemikhali, ii-scraped heat exchangers ezikhutshiweyo zisetyenziswa kakhulu kwimveliso ye-polymer, ukufudumeza ioyile enzima kunye nezinye iinkqubo. Kwimveliso ye-polymer, i-viscosity yezinto ziyatshintsha ngenkqubo yokusabela, ekunzima ukuyiqhelanisa ne-heat exchanger yendabuko, kodwa i-scraper heat exchanger inokuhlala igcina ukudluliselwa kobushushu okusebenzayo. Kwinkqubo yokucocwa kwepetroliyam, i-scraper heat exchanger isetyenziselwa ukufudumeza ioyile enzima, i-asphalt kunye nezinye izinto, nto leyo esombulula ingxaki yokucola.

 

Kwixesha elizayo, uphuhliso lwezixhobo zokutshintshiselana ubushushu bomphezulu ezikhutshiweyo luya kuphuhliswa kwicala lobukrelekrele, ukusebenza kakuhle okuphezulu kunye nemisebenzi emininzi. Ngokuphathelele ubukrelekrele, izinzwa ezingaphezulu kunye neenkqubo zolawulo ziya kuhlanganiswa ukuze kufezekiswe ukujonga ngexesha langempela kunye nokulungiswa ngokuzenzekelayo kweeparamitha zokusebenza. Uphuhliso lwesayensi yezinto luya kuzisa izinto ezintsha ezinganyangekiyo kwaye zinganyangekiyo kwaye zandise ubomi benkonzo yezixhobo. Ukongeza, uyilo lwemodyuli luya kuba ngumkhwa wokwenza lula ukugcinwa kunye nokuphuculwa kwezixhobo.

 

Njengohlobo lwezixhobo zokutshintshiselana ubushushu ezisebenzayo, isixhobo sokutshintshiselana ubushushu esikrazulayo sidlala indima engenakutshintshwa kwimveliso yemizi-mveliso yanamhlanje. Ngokuqhubeka kweteknoloji, intsimi yaso yokusetyenziswa iya kwandiswa ngakumbi, kwaye ukusebenza kwaso kuya kuqhubeka kuphucuka. Kwixesha elizayo, isixhobo sokutshintshiselana ubushushu esikrazulayo siya kwenza igalelo elikhulu ekongeni amandla nasekunciphiseni ukukhutshwa komoya, siphucule ukusebenza kakuhle kwemveliso, kwaye sinike inkxaso enamandla kuphuhliso oluzinzileyo lwemveliso yemizi-mveliso.
