I-tube yokushintshanisa yokushisa yinto yokushintshanisa ukushisa kwe-exchanger yokushisa. Izici zekhwalithi nezindlela zokusebenza zeshubhu lokushintshanisa ukushisa zizothinta umsebenzi wokushintshanisa ukushisa nokusebenza kokushisa kokushisa. Ngakho-ke, ukuze usebenzise kangcono ishubhu lokushintshanisa ukushisa, kuyadingeka ukukhetha ngokucophelela futhi ubhekane nakho kahle. Ngaphansi kwezimo ezijwayelekile, sincoma ukuthi ukhethe ishubhu lensimbi engenasici ngemuva ngoba linokumelana kahle nokugqwala; Futhi ukwelashwa kweshubhu lokushisa lokushisa insimbi elingagqwali kubandakanya ikakhulukazi: Ukwelashwa kokushisa, ukwelashwa okugaya, ukujikeleza kokukhamba, njll. Ngakho-ke, uyazi yini ukuthi ukwelashwa kokushisa kwensimbi yokushisa insimbi engagqwali kwenziwa kanjani? Okulandelayo, imishini yaseSeko izokukhombisa nonke.
Ukwakheka kwe-tube yensimbi engenasici kungashintshwa ngokushisa ukwelashwa, futhi imishini ingashintshwa. Isibonelo, i-06CRCR19NI10 I-Stainless Steach Eate Exchange Tube inokuqukethwe okuphansi kwekhabhoni. Noma ngabe kusetshenziswa ngokwejwayelekile, kunzima ukufeza ubulukhuni obudingekayo bendawo yokushaywa izinyo, futhi impilo ithuluzi liyancishiswa. Isakhiwo esiphansi sekhabhoni kanye ne-Ferrite sitholakala ngemuva kokuqothuka okungaphelele, kanye nobulukhuni (i-HRC20 ~ 25) kuyathuthukiswa. Hhayi kuphela ubulukhuni bendawo ehlangabezana nezidingo, kepha impilo ye-tube yokushisa yokushisa insimbi engagqwali inyuke ngezikhathi ezi-3 kuye kwezine, ngakho-ke ukuze kusetshenziswe kangcono amashubhu okushisa okushisa okushisa okushisa insimbi adinga ukwelashwa kwamashubhu wensimbi engagqwali.
Ukukhetha okulungile kwenqubo yokwelashwa kokushisa yifektri yepayipi yensimbi engenasici kungathuthukisa ukusebenza kahle kwensimbi. Isibonelo, elawula ngokuqinile nengxenyana ye-carbon engxenyeni ebekiwe (hhayi eyeqiwe w = 1.10%), ukuqeda i-carbides yenethiwekhi, njll., Kungathuthukisa ukusebenza kokugaya kokushisa kweshubhu.
Ukwelashwa kokushisa kwamashubhu okushisa okushisa okushisa okungagqwali emazweni aphesheya ngokuvamile kusebenzisa i-non-oxidation ukwelashwa okuqhubekayo kokushisa okushisa ngegesi evikelayo. Ukwelashwa okushisa okuphakathi kwenqubo yokukhiqiza kanye nokwelashwa kokugcina komkhiqizo oqediwe kwenziwa. Njengendawo ekhanyayo ngaphandle kwe-oxidation ingatholakala, i-acid yendabuko iyasuswa. Inqubo yokugeza, ukusetshenziswa kwale nqubo yokwelashwa kokushisa akugcini nje ngokuthuthukisa ikhwalithi yamapayipi ensimbi, kepha futhi kuyanqoba ukungcoliswa kwemvelo okubangelwa ukukha.
Ngokwenkanyezi yamanje yokuthuthukiswa komhlaba, izinyanga eziqhubekayo ezihlangene zihlukaniswe ngezinhlobo ezintathu:
. Igesi evikelayo engasetshenziselwa lolu hlobo lomfanekiso lwe-hydrogen oluhlangene, olubolile i-ammonia namanye amagesi avikelayo. Ingafakwa ngohlelo lokupholisa ukuxhumanisa ukupholisa ipayipi lensimbi ngokushesha. Ilungele ukwelashwa okushisa kosayizi omkhulu namapayipi ensimbi amakhulu. Ukukhishwa ngehora kungamathani ayi-1,0. ephezulu. I-Hanao Tech (Seko Tech (Seko Imishini) ikhethekile kakhulu emkhakheni walokhu I-Roller-Hearture eqhubekayo yekhoyili ekhanyayo yomlilo . Ngaphezu kokuvumelanisa kwesivinini sangaphambi nangemuva somugqa wonke, senze umsebenzi omuhle kakhulu ekulinganiseni ukulawulwa kokushisa nokuqina komoya. Umkhiqizi we-Tube Owangenile Ongenazinsimbi Wokushisa Obungemuva Wokushisa Obungemuva Wokushisa uphenduke umsebenzisi othembekile womkhiqizo wethu.
. Ukukhishwa ngehora kucishe kube ngu-0.3-1.0 amathani, futhi ubude bepayipi lensimbi bungafinyelela kumamitha angama-40, futhi bungacubungula namashubhu we-capillary kumakhoyili.
(3) Uhlobo lwe-muffle hlobo lokushisa ukushisa okukhanyayo. Ukufaka ipayipi lensimbi kwi-rack eqhubekayo futhi kugijime ukufudumala ku-muffle tube. Le ndlela yokwelashwa kokushisa ingacubungula amapayipi ensimbi amancane asezingeni eliphakeme ngezindleko eziphansi, kanti ukuphuma ngehora cishe amathani angama-0,3 noma ngaphezulu.
