I-Scraped Surface exchanger ubushushu: Umgaqo, isicelo kunye nophuhliso lwexesha elizayo

I-scraped surface heat exchanger luhlobo lwezixhobo ezisebenzayo zokutshintshiselana kobushushu, ezidlala indima ebalulekileyo ekutyeni, kwiikhemikhali, kumayeza kunye namanye amashishini. Ngokusebenzisa umatshini okhethekileyo wesakhiwo kunye nemodi yokusebenza, olu hlobo lokutshintsha ubushushu lusombulula ingxaki yokutshintsha ubushushu bendabuko ekujonganeni ne-viscosity ephezulu kunye nokulula ukulinganisa izinto. Eli phepha liza kuhlalutya ngokubanzi i-scraper heat exchanger, isixhobo esibalulekileyo soshishino, ukusuka kwimiba yomgaqo-siseko wokusebenza, iimpawu zesakhiwo, imimandla yesicelo kunye neendlela zokuphuhliswa kwexesha elizayo.

 Okokuqala, umgaqo wokusebenza kunye nesakhiwo se-scraped surface heat exchanger

Umgaqo-siseko osebenzayo we-scraper surface heat exchanger kukuqhuba ngokuqhubekayo indawo yokutshintsha ubushushu ngokujikeleza i-scraper ukuphumeza ukuhanjiswa kobushushu obusebenzayo. Isakhiwo esisisiseko siquka umzimba wokutshintsha ubushushu be-cylindrical, i-shaft ejikelezayo, indibano ye-scraper, isixhobo sokuqhuba kunye nenkqubo yokutywinwa. Umzimba wokutshintsha ubushushu udla ngokuba yi-double-layer structure, kwaye indawo yokufudumeza okanye yokupholisa idluliselwe phakathi. I-shaft ejikelezayo ixhotywe ngobuninzi be-scrapers, ekufutshane nodonga lwangaphakathi lwe-cylinder phantsi kwesenzo samandla e-centrifugal kwaye iqhube ngokuqhubekayo indawo yokudlulisa ukushisa ngokujikeleza kwe-shaft.

 Ngethuba lenkqubo yokusebenza, izinto eziza kuphathwa zingena kwi-heat exchanger ukusuka kwindawo ephezulu kwaye zigeleza phantsi kodonga lwangaphakathi lwe-cylinder phantsi kwesenzo sobunzima. I-scraper ejikelezayo ayidlali kuphela indima yokuxuba, kodwa ngokubaluleke ngakumbi, ihlaziya rhoqo ifilimu yezinto eziphathekayo kwindawo yokudlulisa ukushisa ukukhusela izinto ezivela kwi-coking okanye ukulinganisa kwindawo yokushisa ephezulu. Le ndlela yokuhlaziya ifilimu ivumela utshintshiselwano lobushushu olukhutshiweyo ukuba lufezekise ukusebenza kakuhle kokugqithisela ubushushu, ngokufuthi ukuya kuthi ga kwi-3-5 amaxesha obushushu obuqhelekileyo.

 Icandelo eliphambili le-scraped surface heat exchanger yinkqubo ye-scraper, i-design yayo ichaphazela ngokuthe ngqo ukusebenza kwezixhobo. Abatshintshi bobushushu bomphezulu banamhlanje basebenzisa i-scraper ehlengahlengiswayo, ngokusebenzisa intwasahlobo okanye amandla e-centrifugal ukulungisa uxinzelelo lonxibelelwano phakathi kwe-scraper kunye nodonga lwesilinda, kungekuphela nje ukuqinisekisa isiphumo esihle sokukhuhla, kodwa nokuphepha ukunxiba okugqithisileyo. Inkqubo yokutywina nayo iyinxalenye ebalulekileyo, zombini ukukhusela ukuvuza kwezinto, kodwa kunye nokuqinisekisa ukusebenza kakuhle kwe-shaft ejikelezayo.

 

Okwesibini, iingenelo zobugcisa kunye nokunciphisa i-scraped surface heat exchanger

Inzuzo ebaluleke kakhulu ye-scraper exchanger heat exchanger yikhono layo lokuphatha izinto ezibonakalayo ezibonakalayo, ezinobushushu. Kwintsimi yokulungiswa kokutya, njengokuveliswa kwe-majarini ye-puff pastry, itshokolethi, i-jam, itshizi kunye nezinye iimveliso, ukutshintshwa kobushushu bendabuko kunzima ukuhlangabezana neemfuno zenkqubo, kwaye i-scraper heat exchanger inokusombulula ngokugqibeleleyo ezi ngxaki. I-coefficient yokudlulisa ubushushu inokufikelela kwi-2000-5000W/(m²·K), iphezulu kakhulu kuneqokobhe eliqhelekileyo kunye nesitshintshisi sobushushu setyhubhu.

 

Xa ujongene nezinto ezilula ukulinganisa, iingenelo ze-scraper exchanger heat exchanger ziyabonakala ngakumbi. Kwishishini le-petrochemical, i-oyile enzima, i-asphalt kunye nezinye izinto zilula ukupheka kwindawo yokudlulisa ubushushu ngexesha lenkqubo yokufudumeza, kwaye abatshintshi bobushushu bendabuko bafuna ixesha lokucoca rhoqo. I-scraper heat exchanger ngokusebenzisa i-scraping effect eqhubekayo, ukukhusela ngokufanelekileyo i-coking phenomenon, ukwandisa kakhulu ixesha eliqhubekayo lokuhamba.

 

Nangona kunjalo, abatshintshi bobushushu bomhlaba okhutshiweyo nabo banemida ethile. Eyokuqala yindleko ephezulu yezixhobo, ngenxa yesakhiwo sayo esiyinkimbinkimbi kunye neemfuno zokulungiswa ngokuchanekileyo, utyalo-mali lokuqala lukhulu kakhulu kunokutshintshana kobushushu obuqhelekileyo. Okwesibini, iindleko zokugcinwa ziphezulu, kwaye i-scraper kunye ne-seal zizinto ezisengozini kwaye kufuneka zitshintshwe rhoqo. Ukongezelela, xa ujongene nezixhobo eziphantsi kwe-viscosity, izibonelelo zayo azibonakali, kodwa zinokunyusa ukusetyenziswa kwamandla ngenxa yokuxuba oomatshini.

 

Okwesithathu, indawo yesicelo kunye nophuhliso lwexesha elizayo lomtshintshi wobushushu okhutshiweyo

Kwishishini lokutya, i-scraped over heat exchangers isetyenziswa ngokubanzi kwi-chocolate tempering, i-jam sterilization, i-crystallization yebhotolo kunye nezinye iinkqubo. Ngokomzekelo, ekuveliseni i-tshokoleta, izinto eziphathekayo kufuneka zilawulwe ngokuchanekileyo kwiqondo lokushisa elithile lonyango lokulawula ubushushu, kwaye i-scraper exchanger heat exchanger inokufikelela kulawulo oluchanekileyo lokushisa kunye nokutshintshwa kobushushu obufanayo ukuqinisekisa umgangatho wemveliso.

 

Kwinkalo yoshishino lweekhemikhali, i-scraped surface heat exchangers isetyenziswa kakhulu kwimveliso ye-polymer, ukufudumeza kweoli enzima kunye nezinye iinkqubo. Kwimveliso ye-polymer, i-viscosity yezinto eziphathekayo iyatshintsha kunye nenkqubo yokuphendula, okunzima ukuyiqhelanisa nobushushu bendabuko, kodwa i-scraper heat exchanger inokuhlala igcina ukuhanjiswa kobushushu obusebenzayo. Kwinkqubo yokucoca i-petroleum, i-scraper exchanger heat exchanger isetyenziselwa ukutshisa ioli enzima, i-asphalt kunye nezinye izinto, ezisombulula ingxaki yokupheka.

 

Kwixesha elizayo, ukuphuhliswa kokutshintsha kobushushu bomhlaba okhutshiweyo kuya kuphuhlisa kwicala lobukrelekrele, ukusebenza kakuhle okuphezulu kunye nemisebenzi emininzi. Ngokumalunga nobukrelekrele, ii-sensor ezininzi kunye neenkqubo zokulawula ziya kuhlanganiswa ukuphumeza ukubeka iliso ngexesha langempela kunye nokulungiswa ngokuzenzekelayo kweeparamitha zokusebenza. Ukuphuhliswa kwenzululwazi yezixhobo kuya kuzisa izinto ezintsha ezingagugiyo kunye ne-corrosion-resistant kunye nokwandisa ubomi benkonzo yezixhobo. Ukongeza, uyilo lweemodyuli luya kuba ngumkhwa wokuququzelela ukugcinwa nokuphuculwa kwezixhobo.

 

Njengohlobo olusebenzayo lwezixhobo zokutshintshiselana kobushushu, i-scraper exchanger heat exchanger idlala indima engenakuthathelwa indawo kwimveliso yale mihla. Ngenkqubela phambili eqhubekayo yeteknoloji, intsimi yesicelo sayo iya kwandiswa ngakumbi, kwaye ukusebenza kwayo kuya kuqhubeka nokuphucula. Kwixesha elizayo, i-heat exchanger ye-scraper iya kwenza igalelo elikhulu ekugcinweni kwamandla kunye nokunciphisa ukukhutshwa, ukuphucula ukusebenza kwemveliso, kunye nokubonelela ngenkxaso eqinile yophuhliso oluzinzileyo lwemveliso yezoshishino.
