I-Plate heat exchanger iwuhlobo lwemishini yokushintshanisa ukushisa, enezinzuzo ezinye izisetshenziswa zokushintshanisa ukushisa ezingakwazi ukufana nayo: ine-coefficient yokudlulisa ukushisa okuphezulu, ukulahlekelwa ukushisa okuphansi, indawo encane, ukwakheka okuhlangene nokukhanya, ukugcinwa okulula nokuhlanza, Abashintshi bokushisa bamapuleti banezinhlobonhlobo zezinhlelo zokusebenza nempilo ende yesevisi. Kodwa-ke, ziphinde zibe nobubi obuthile, njengokuthi ukucindezela akukwazi ukudlula ku-2.5Mpa, izinga lokushisa alikwazi ukudlula ama-degree Celsius angu-250, azikwazi ukushintshanisa ukushisa ukuze zibe izinhlayiya ezinkulu nemicu emide, azikwazi ukusetshenziswa ezimweni zokusebenza ezigqwala kakhulu, futhi zivame ukucinana. Okulandelayo ukuhlaziya ezinye zezimo ezingavamile ezivamile zeizishintshi zokushisa:
Izizathu ezibalulekile:
Ukukala/ukuvala amapuleti okushintshanisa ukushisa: I-calcium ne-magnesium ion kanye nokungcola oketshezini kufakwa phezu kwamapuleti, okwenza ungqimba lwesikali olunokushisa okuphansi kakhulu; umjikelezo omfushane owuketshezi: ama-gasket avala amapuleti ayaguga noma awahambelani kahle,Lokhu kubangela ukuthi uketshezi olubandayo nolushisayo luhlangane ngqo ngaphandle kokushintshaniswa nokushisa; ukuvinjelwa kwesiteshi sepuleti: izinhlayiya eziqinile nemicu (njengamapayipi endle nodaka) oketshezini kunamathele endaweni yomhlahlandlela wamapuleti noma kumzila wokugeleza, kunciphisa indawo esebenzayo yokushintshanisa ukushisa.
Isixazululo:
01
Ukwehliswa kwamakhemikhali (ukukala):
Misa okokusebenza, khipha uketshezi, futhi ugeze nge-ejenti yokuhlanza ene-asidi ebuthaka (njengesisombululo se-citric acid esingu-5% -8% ukugwema ukugqwala kwamapuleti ensimbi engagqwali) amahora angu-2-4,
02
bese uhlanza ngamanzi ahlanzekile kuze kube yilapho ungathathi hlangothi;Uma ungqimba lwesikali luqinile (njenge-calcium carbonate hard scale), lucwilise ihora elingu-1 ngaphambi kokujikeleza kabusha.
03
Ungasebenzisi izixazululo ezonakalisa kakhulu njenge-hydrochloric acid (engase ilimaze kalula ifilimu ye-plate passivation).
04
Ukuhlanza umzimba (ukuvinjelwa):
Hlukanisa isishintshi sokushisa, khipha amapuleti, futhi ushaye umzila wokugeleza -ngesibhamu samanzi sokucindezela okuphezulu (cindezela Ngaphansi noma okulingana no-0.8MPa ukuze ugweme ukonakala kwamapuleti);
Izizathu ezibalulekile:Ukuguga/ukulimala kwe-gasket: izinga lokushisa eliphezulu-lesikhathi eside kanye nokuguquguquka kwengcindezi kubangela ukuba i-gasket ilahlekelwe ukunwebeka, noma ukugqwala okuwuketshezi (okufana noketshezi olune-asidi) kubangela ukuthi i-gasket ivuvuke futhi iqhekeke; Ukuguqulwa kwepuleti/ukungalungi kahle: Ukuqiniswa okungalingani kwamabhawodi ngesikhathi sokuhlanganisa Noma{1}}ukusebenza kwesikhathi eside kokucindezela ngokweqile kubangela ukungqubuzana kwamapuleti kanye nezindawo zokuvala ezixegayo; ukwehluleka kophawu lwe-flange: ubudala be-flange flange gaskets, noma amabhawodi ayaxega (ukushintshashintsha kokushisa nokubanda kubangela ukuba amabhawodi ande futhi anciphe). Ukuvuza kokucisha kubangelwa ikakhulukazi ukuqala{3}}ukuvalwa nokuvalwa kwesishintshi sokushisa, futhi ukubuyiselwa kwezimo zokusebenza ezivamile kungenzeka; ukuvuza kwangaphakathi kubangelwa ikakhulukazi ama-gaskets alimele kanye nokugqwala kwamapuleti kanye nokubhoboza;Izizathu eziyinhloko zokuvuza kwangaphandle ukungaboni ngaso linye, ukukhishwa, ukulimala kwe-gasket evala, ukugqwala kanye nokuguqulwa kwepuleti, kanye nokwehluleka ukuqina kusayizi oshiwo wokubamba; isizathu esiyinhloko sokuvuza phakathi kwepuleti eliyimpumputhe kanye ne-clamping plate ukuthi ipuleti eliyimpumputhe libhobozwa izinto eziqinile.
Isixazululo:Ukwelashwa kwezimo eziphuthumayo: nciphisa ngokushesha ingcindezi yesistimu, vala indawo yokushintshanisa ukushisa namavalvu okukhipha (vala uhlangothi olushisayo kuqala, bese kuba olubandayo), khipha uketshezi bese uvala; buyisela ama-seal: qaqa isishintshi sokushisa, susa wonke ama-gaskets,Hlola umsele wokuvala amapuleti ukuze uthole imihuzuko (uma ikhona, bushelelezi nge-sandpaper enhle); buyisela i-gasket evalayo ngohlobo olufanayo (kunconywa ukuthi usebenzise ukushisa-okumelana nokubola{1}}okuqinile, njengenjoloba ye-nitrile kawoyela kanye ne-EPDM yamanzi/i-alkali ebuthakathaka); Hlanganisa kabusha futhi uqinise: beka amapuleti ngohlelo lwangempela (izinombolo zamapuleti kufanele ziqondaniswe ukuze ugweme ukuhlehla kwezinyathelo zasendaweni), futhi uqinise ukufakwa kwe-boa ingcindezi);
Umehluko phakathi kwamageji engcindezi yokungena nokuphumayo yesishintshi sokushisa idlula inani lokuklama (isibonelo, ingcindezi yokuklama yehla ngo-0.1MPa, kodwa ingcindezi yangempela yehla ibe ngu-0.3MPa); ingcindezi yokuphuma kwephampu iyanda, kodwa iisishintshi sokushisaizinga lokugeleza kwe-inlet liyancipha (ipompo igcwele ngokweqile futhi umsindo uyanda).
Izizathu ezibalulekile:Ukuvinjwa kwesiteshi esigelezayo: ukungcola oketshezini (okufana nesihlabathi nokugqwala) kufakwe kushaneli yokugeleza kwepuleti, kunciphisa ukugeleza-indawo yesigaba;Inombolo engalungile noma uhlobo lwamapuleti: Izinga lokugeleza langempela lidlula kude inani lomklamo, noma ishaneli yokugeleza kwepuleti lincane kakhulu (isibonelo, ipuleti elincane lesiteshi lisetshenziselwa ukucubungula izinga lokugeleza okukhulu kwe-viscob: i-viscob uketshezi oluphansi kakhulu); i-viscosity yamafutha iyanda emazingeni okushisa aphansi), noma uketshezi luqukethe inani elikhulu lezinto ezimisiwe (ezifana ne-slurry), okuholela ekwandeni kokuphikiswa kokugeleza.
Isixazululo: Hlanza ishaneli yokugeleza: Ngemva kokuvala, qaqa isishintshi sokushisa futhi usule isiteshi sokugeleza kwepuleti ngesibhamu samanzi somfutho ophezulu-, noma sebenzisa ibhola elikhethekile (elinobubanzi obuncane kancane kunobubanzi besiteshi sokugeleza) ukuze usule ukuvaleka; lungisa imingcele yokusebenza: uma izinga lokugeleza likhulu kakhulu, nciphisa ngokufanelekile imvamisa yepompo (yilawule ngaphakathi kwebanga elingu-± 10% lokugeleza kokuklama); uma i-viscosity yoketshezi iphezulu, nyusa izinga lokushisa lokungena uketshezi (njengokushisa uwoyela ebangeni elifanele le-viscosity), noma faka i-preheater endaweni yokungena.
a: Izinga lokushisa eliseceleni elishisayo lingaphezulu kwenani lokuklama. Izizathu eziyinhloko yilezi: inkinga yokukhetha, izinga lokugeleza ohlangothini olushisayo likhulu kunenani lokuklama, ipuleti ivinjiwe noma izinga lokugeleza ohlangothini olubandayo lincane;
b:Izinga lokushisa eliseceleni elibandayo liphansi kakhulu. Izizathu eziyinhloko ukugeleza okuncane okushisayo ohlangothini noma izinga lokushisa eliphansi kunenani lokuklama, ukuvinjelwa kwepuleti, njll.
