Izinhlobo zokushisa ukushisa. Isimiso sokusebenza kokushisa kokushisa

Kungekudala, cishe wonke ama-exchange exchanges aphethe ukwakhiwa kwegobolondo ne-tube, lapho isikhulu sasigijimelana komunye nomunye, sihamba ngezintambo. Izakhi zokugcina zibekwe omunye komunye. Kodwa ngisho nanamuhla isisetshenziswa esinjalo sokushisa ukushisa into yesikhathi esidlule. Amadivaysi anjalo ahlukumezeka, kodwa asebenza kahle. Phakathi kokungaphumeleli kwabo kungabonakala ukusetshenziswa okukhulu kwesidingo esishisayo. Uma ucabangela izinhlobo zokushisa ukushisa, kufanele uqaphele ukuthi namuhla amadivaysi amasha ashintshwa yizinyathelo eziphezulu ezichazwe ngenhla.

Isimiso sokusebenza kwe-plate heat exchanger

Uma ucabangela izinhlobo zokushisa ukushisa, kubalulekile ukukhokha ngokukhethekile uhlobo lweplate lamadivaysi anjalo. Ngokwemvelo, la madivaysi ahluke ku-precursor we-shell-and-tube. Esikhathini esilandelayo, indawo yendawo yokushintshaniswa kwamandla yanda ikhuliswa ngenxa yobude obuhlaba umxhwele bekhoyili, okuyiwona owabangela ukulingana okuthakazelisayo kwedivayisi. Uma sikhuluma ngomthengisi omusha wokushisa, umgomo uthola ngokukhulisa inani lamapuleti anendawo efanayo. Izinhlobo zanamuhla zokushisa ukushisa zinamandla afanayo, kodwa ngesayizi ziphindwe kathathu kunamamodeli we-shell-and-tube. Amadivaysi amasha anika izinga lokugeleza elimangalisayo lomthombo oshisayo, osetshenziselwa izidingo zamanzi ashisayo. Lokhu kwaholela eqinisweni lokuthi leyunithi yathola igama lesibili - libizwa ngokuthi umthengisi wokushisa okusheshayo. Amadivaysi afanayo analo ekubunjweni kokubuyisela nokuhlinzeka ngamapayipi, asetshenziselwa ukuxhuma isikhala sokushisa, njengoba izenzo zokugcina zipholile.

Izici zedivayisi nedivayisi

Idivayisi inokungena kanye nesilwane semidiya evuthayo. Ungabona ekwakheni i-plate fixed, ekhonjisiwe. Kukhona izimbobo zamanzi kudivayisi. Umthengisi wokushisa ngeke futhi asebenze ngaphandle kwe-gasket, emelelwa ngendandatho, kanye nekhabetheni lokushisa lokushisa lokushisa. Kukhona ipulethi elihambayo elihambayo kanye neziqondiso ezingaphezulu kumklamo. Idivayisi ifakwe ukwesekwa kwangemuva, i-hairpin ne-gasket, etholakala emgqeni weplate.

Izinhlobo ezichazwayo zokushintshisa ukushisa zisetshenziselwa Ukushisa umklamo olula ngamacubula, atholakala ezinhlangothini eziphambene nedivayisi. Phakathi kwamacwecwe asezikhombini ezimbili, inani lamapuleti anompawu phakathi kwabo ahlungwa. Emaceleni, ukwandisa ubuso bezokushintshanisa, kukhona ukuphumula okukhululekile. Kwamanye amamodeli, amapayipi egatsha asehlangothini olulodwa lwamadivaysi, ayeseceleni ephambili, okuyinto, okwamanje, engathinti ukusebenza kwedivaysi yeplate. Ama-exchange exchange exchangers asebenza ngokuvumelana nesimiso esihilela ukugcwalisa isikhala esiphakathi kwezibhebhe ezinezikhala ezifudumele.

Ulwazi olungeziwe ngomsebenzi

Amafomu e-gaskets anquma umyalelo wokugcwalisa: emnyangweni owodwa bavula indlela yokuhambisa amanzi, kwesinye isigaba ukushisa kufakwa. Ngenkambiso yokusebenza kwamadivayisi wesigaba ngasinye, ngaphezu kokugcina neyokuqala, umuntu angaqaphela ukushintshaniswa okushisa kunalokho okunamandla ngokusebenzisa ipuleti ezinhlangothini zombili. Ama-mediums ageleza ezigabeni, eqondana komunye nomunye. Umshini wokushisa uvela phezulu, kodwa uphuma ngepayipi elingaphansi legatsha. Ngokuqondene nokufutheka, kulandela isiqondiso esibhekene nendawo yokushisa.

Izinhlobo zokushisa ukushisa

Kuthengiswa namuhla ungathola umshini wokushisa wokushisa-iron, kodwa kukhona amanye amadivaysi ezenziwe ezinye izinto. Izinhlobo zamadivaysi afanayo zihanjiswa ngendlela ehlukahlukene. Ukusetshenziswa kwabo akukhawulelwanga endaweni eyodwa yomkhakha, ama-unit manje asetshenziselwa yonke indawo: ku-metallurgy, imboni yamakhemikhali, ubuchwepheshe bamandla, amaphuzu okushisa, ukushisa, ukushisa umoya kanye nezinhlelo zokuphumula.

Umehluko endleleni yokudlulisa ukushisa

Uma ufuna ukufaka isithando somlilo ngomthengisi wokushisa, kufanele uqale uqonde izinhlobo zamadivayisi achazwe kulesi sihloko. Ngakho-ke, zingahle zihlukaniswe nendlela yokudlulisa ukufudumala, kule ndaba zingaba phezulu nokuxuba. Esikhathini sokuqala, ukushintshanisa ukushisa kwenzeka phakathi kwemidiya ehlukene ngokusebenzisa izindonga ezenziwe ngendaba ekhethekile yokuqhuba ukushisa. Kule nkinga, lo mdlalo uhlale uphelele ngokuphelele. Uma unesithakazelo kumshini wohlobo oluphezulu, kufanele uqaphele ukuthi kukhona amadivaysi okuvuselela nokuvuselela. Esikhathini esilandelayo, ukushintshaniswa kwamazinga okushisa phakathi kwezingxenye zokushisa kwenzeka ngezindonga ezincane zemizila, kanti ukugeleza kwesikhulumi kunendlela efanayo. Esimweni sesibili, ukuqondiswa kokugeleza kungahluka. Uma unquma ukufaka umthengisi wokushisa kwegesi, kufanele uqaphele izinguqulo zokuxuba zamadivayisi. Ukudlulisa ukushisa kuzo kwenzeka ngokuxuba abezindaba ababili, kodwa amadivaysi alolu hlobo asetshenziswa kaningi kunalokho okukhulunywe ngenhla.

Izinhlobo zokushintshisa ukushisa emkhakheni wokusetshenziswa

Uma umnikazi wendlu yangasese noma yendawo yasemadolobheni enquma ukufaka isithando somlilo nge-exchanger yokushisa, uvame ukukhetha uhlelo lwe-shell-and-tube elinomthwalo wamathebhu axhunyiwe komunye igridi nge-welding kanye ne-soldering. Olunye uhlobo yi-plate exchange exchangers, okukhulunywe ngaye ngenhla, banendawo yokushintshanisa ukushisa, ekhonjiswe ngendlela yamacwecwe. Lezi zinsuku zihlanganiswa ndawonye ngamasimbali angenakushisa. Amakhoyili agqamile asetshenziselwa ukukhuphula ukushintshana kokushisa, ukusebenza okuphakathi kwawo kudluliselwa emaphepheni ajika, kanye nendawo phakathi kwamapayipi.

Awukwazi ukuphuthelwa kumadivayisi okuvunguza, amele amashidi ensimbi amancane. Zihlanganiswe ngokuvutha ngesikhathi sokukhiqiza. Uhlu olwethulwe aluphelelanga, phakathi kwezinto ezivame kakhulu singakwazi ukugqamisa umoya, kanye namadivayisi amanzi.

Umthengisi wokushisa, amanani akhe angaba ngama-ruble angu-7000, anikezwe namuhla ngezinhlobonhlobo. Kulula nje ukuhlunga zonke izinhlobo zama-aggregates, ngakho-ke kuphela okuthandwa kakhulu okwethulwa ngenhla. Umholi phakathi kwabo ngu-lamellar.

Izinhlobo zamadivayisi epuleti

Ama-exchange exchange exchangers ahlinzekwa ngokudayiswa ngezindlela ezihlukahlukene, angahle ahlaziyeke, ahlaziyeke, ahlangene futhi aphethwe yi-welded. Izinhlobonhlobo zokuqala zaxoxwa ngenhla, kepha ngokuqondene ne-soldered version, inezinsimbi zensimbi ezonakele ezenziwe ngensimbi engagqwali. Lezi zakhi zixhunyaniswe ndawonye ngokugaya izimo eziphuthumayo usebenzisa i-nickel noma i-solder yethusi.

Isiphetho

Umthengisi wokushisa (intengo ekhonjiswe ngenhla) nayo ingasuswa. Amadivaysi anjalo ahloselwe ukusebenza ezimweni zokushisa okuphezulu nokucindezela okukhulu. Zisetshenziswe ekufakweni okungekho imingcele engavumeli ukusetshenziswa kwezakhi zokufaka uphawu.
