Scraped Surface heat exchanger: Molao-motheo, ts'ebeliso le nts'etsopele ea nako e tlang

Mocheso oa mocheso oa holim'a metsi ke mofuta oa lisebelisoa tse sebetsang hantle tsa ho fapanyetsana mocheso, tse phethang karolo ea bohlokoa liindastering tsa lijo, lik'hemik'hale, tsa meriana le tse ling. Ka sebopeho se ikhethileng sa mochini le mokhoa oa ts'ebetso, mofuta ona oa mocheso oa mocheso o rarolla bothata ba mochini oa mocheso oa setso ha o sebetsana le viscosity e phahameng le lisebelisoa tse bonolo tsa ho lekanya. Pampiri ena e tla sekaseka ka botlalo mochini oa mocheso oa scraper, lisebelisoa tsa bohlokoa tsa indasteri, ho tloha lintlheng tsa molao-motheo oa ts'ebetso, litšobotsi tsa sebopeho, masimo a kopo le mekhoa ea ntlafatso ea nako e tlang.

 Ntlha ea pele, molao-motheo oa ho sebetsa le sebopeho sa mocheso o chesang holim'a metsi

Molao-motheo oa ts'ebetso oa mochini o futhumatsang mocheso ke ho tsoela pele ho senya sebaka sa phapanyetsano ea mocheso ka ho potoloha scraper ho finyella mocheso o sebetsang hantle. Sebopeho sa motheo se kenyelletsa 'mele oa mocheso oa cylindrical, shaft e potolohang, kopano ea scraper, sesebelisoa sa ho khanna le mokhoa oa ho tiisa. 'Mele oa mocheso oa mocheso hangata o na le mohaho o nang le likarolo tse peli,' me mochine oa ho futhumatsa kapa o pholileng o fetisetsoa bohareng. Mokotla o potolohang o na le li-scrapers tse ngata, tse haufi le lerako le ka hare la cylinder tlas'a ketso ea matla a centrifugal le ho tsoela pele ho senya sebaka sa ho fetisa mocheso ka ho potoloha ha sefate.

 Nakong ea ts'ebetso ea ho sebetsa, thepa e lokelang ho phekoloa e kena mocheso oa mocheso ho tloha karolong e ka holimo 'me e phalla ho theosa le lerako le ka hare la silinda tlas'a ketso ea matla a khoheli. The rotating scraper ha e bapale karolo ea ho kopanya feela, empa ho bohlokoa le ho feta, e lula e nchafatsa filimi ea lintho tse bonahalang holim'a mocheso o fetisang mocheso ho thibela thepa hore e se ke ea pheha kapa ea fokotseha holim'a mocheso o phahameng oa mocheso. Mokhoa ona o matla oa ho nchafatsa lifilimi o lumella li-exchanger tsa mocheso tse chekiloeng ho fihlela katleho e phahameng haholo ea ho fetisa mocheso, hangata ho fihlela makhetlo a 3-5 ho feta a li-exchangers tse tloaelehileng tsa mocheso.

 Karolo e ka sehloohong ea mocheso o chesang holim'a metsi ke tsamaiso ea scraper, eo moqapi oa eona o amang ka ho toba ts'ebetsong ea lisebelisoa. Lisebelisoa tsa morao-rao tsa mocheso oa mocheso oa metsi hangata li sebelisa scraper e fetolehang, ka nako ea selemo kapa matla a centrifugal ho lokisa khatello ea ho kopana pakeng tsa scraper le lerako la cylinder, eseng feela ho etsa bonnete ba hore ho na le phello e ntle ea ho senya, empa hape le ho qoba ho apara ho feteletseng. Sistimi ea ho tiisa hape ke karolo ea bohlokoa, ka bobeli ho thibela ho tsoa ha thepa, empa hape le ho netefatsa ts'ebetso e boreleli ea shaft e potolohang.

 

Taba ea bobeli, melemo ea tekheniki le mefokolo ea mochini o futhumatsang mocheso o pharalletseng

Molemo o moholo ka ho fetisisa oa mochine oa mocheso oa scraper ke bokhoni ba oona ba ho sebetsana le lisebelisoa tse nang le li-viscous tse ngata haholo, tse nang le mocheso. Sebakeng sa ho lokisa lijo, joalo ka tlhahiso ea margarine ea puff pastry, chokolete, jeme, chisi le lihlahisoa tse ling, mochini oa mocheso oa setso o thata ho fihlela litlhoko tsa ts'ebetso, 'me mochini oa mocheso oa scraper o ka rarolla mathata ana ka ho phethahetseng. Coefficient ea eona ea ho fetisa mocheso e ka fihla ho 2000-5000W/(m²·K), e phahame haholo ho feta khetla e tloaelehileng le mochini o futhumatsang mocheso.

 

Ha u sebetsana le lisebelisoa tse bonolo ho lekanya, melemo ea mocheso oa mocheso oa scraper e totobetse haholoanyane. Indasteri ea petrochemical, oli e boima, asphalt le lisebelisoa tse ling li bonolo ho li pheha holim'a mocheso oa mocheso nakong ea mocheso, 'me lihlahisoa tsa mocheso tse tloaelehileng li hloka nako ea ho phomola khafetsa bakeng sa ho hloekisa. Mocheso oa mocheso oa scraper ka phello e tsoelang pele ea ho senya, ka katleho e thibela ketsahalo ea coking, e eketsa haholo nako e tsoelang pele ea ho sebetsa.

 

Leha ho le joalo, li-exchanger tsa mocheso tse chekiloeng le tsona li na le mefokolo e itseng. Ea pele ke litšenyehelo tse phahameng tsa thepa, ka lebaka la sebopeho sa eona se rarahaneng sa mechine le litlhoko tsa ho sebetsa ka mokhoa o nepahetseng, letsete la pele le leholo ho feta li-exchangers tse tloaelehileng tsa mocheso. Ea bobeli, litšenyehelo tsa tlhokomelo li phahame, 'me scraper le seal ke likarolo tse tlokotsing' me li hloka ho nkeloa sebaka khafetsa. Ho phaella moo, ha u sebetsana le lisebelisoa tse tlaase tsa viscosity, melemo ea eona ha e totobetse, empa e ka eketsa tšebeliso ea matla ka lebaka la ho kopanya mechine.

 

Ntlha ea boraro, sebaka sa ts'ebeliso le nts'etsopele ea nako e tlang ea mochini o futhumatsang o chesang holim'a metsi

Indastering ea lijo, li-exchanger tsa mocheso tse chekiloeng li sebelisoa haholo ho futhumatsa chokolete, ho etsa jeme, crystallization ea botoro le lits'ebetso tse ling. Ka mohlala, ha ho etsoa tsokolate, thepa e lokela ho laoloa ka mokhoa o nepahetseng ka har'a mocheso o itseng oa mocheso bakeng sa phekolo ea ho laola mocheso, 'me mochine oa mocheso oa scraper o ka finyella taolo e nepahetseng ea mocheso le phapanyetsano ea mocheso o tšoanang ho netefatsa boleng ba sehlahisoa.

 

Lefapheng la indasteri ea lik'hemik'hale, lihlahisoa tsa mocheso o chesang holim'a metsi li sebelisoa haholo-holo tlhahiso ea polymer, ho futhumatsa oli e boima le mekhoa e meng. Ka tlhahiso ea polymer, viscosity ea thepa e fetoha ka mokhoa oa ho itšoara, oo ho leng thata ho ikamahanya le mocheso o tloaelehileng oa mocheso, empa mocheso oa mocheso oa scraper o ka lula o boloka mocheso o sebetsang hantle. Nakong ea ho hloekisa peterole, mochine oa mocheso oa scraper o sebelisetsoa ho futhumatsa oli e boima, asphalt le lisebelisoa tse ling, tse rarollang bothata ba ho pheha.

 

Nakong e tlang, nts'etsopele ea li-exchangers tsa mocheso oa holim'a metsi li tla ntlafala ka tataiso ea bohlale, bokhoni bo phahameng le mesebetsi e mengata. Mabapi le bohlale, li-sensor tse ngata le litsamaiso tsa taolo li tla kopanngoa ho fihlela tlhahlobo ea nako ea nnete le tokiso ea othomathike ea li-parameter tsa ts'ebetso. Nts'etsopele ea mahlale a thepa e tla tlisa lisebelisoa tse ncha tse sa senyeheng le tse thibelang ho bola le ho lelefatsa bophelo ba ts'ebeletso ea lisebelisoa. Ntle le moo, moralo oa modular o tla fetoha mokhoa oa ho tsamaisa tlhokomelo le ntlafatso ea lisebelisoa.

 

Joalo ka mofuta oa sesebelisoa se sebetsang hantle sa phapanyetsano ea mocheso, mochini oa mocheso oa scraper o bapala karolo e ke keng ea nkeloa sebaka tlhahisong ea sejoale-joale ea indasteri. Ka tsoelo-pele e tsoelang pele ea thekenoloji, tšimo ea eona ea ts'ebeliso e tla atolosoa le ho feta, 'me ts'ebetso ea eona e tla tsoela pele ho ntlafala. Nakong e tlang, mochine oa mocheso oa scraper o tla fana ka menehelo e kholo ea ho boloka matla le ho fokotsa mocheso, ho ntlafatsa katleho ea tlhahiso, le ho fana ka tšehetso e matla bakeng sa tsoelo-pele e tsitsitseng ea tlhahiso ea indasteri.
