Yuav ua li cas los daws qhov poob ntawm graphite tshav kub exchanger ntawm qhov kub thiab txias

Cov khoom siv hluav taws xob graphite yog ua los ntawm cov khoom siv graphite. Vim tias graphite muaj cov kua qaub tiv thaiv corrosion thiab zoo thermal conductivity, graphite core yog tsim los rau hauv cov qauv thaiv-qhov sib cais vertically thiab horizontally. Thaum ob lub xov xwm dhau los ntawm ib leeg, qhov kub thiab txias Qhov nruab nrab tsis tu ncua hloov cov cua sov mus rau graphite tshav kub exchanger, thiab qhov nruab nrab kub nruab nrab tsis tu ncua tau txais cua sov los ntawm graphite tshav kub exchanger, yog li ntse realizing tshav kub exchanger. Cov khoom siv hluav taws xob graphite yog tsim rau cov khoom siv tsis muaj oxidizing lossis tsis muaj zog oxidizing muaj zog acids, alkalis, ntsev tov, organic Acid feem ntau cov kuab tshuaj organic thiab cov xov xwm nyuaj. Lub thermal conductivity yog siab dua li ntawm ntau cov hlau, cov linear expansion coefficient yog me me, kub tsis kam, thermal shock resistance, nto tsis yooj yim rau scale, tsis muaj kuab paug, thiab machining kev ua tau zoo. Tsawg ceev thiab lub teeb yuag.

Ua ntej siv, xyuas seb qhov kev sib txuas thiab kev rwb thaiv tsev ntawm cov kav dej txias ntawm cov khoom siv hluav taws xob graphite yog qhov zoo. Thaum siv, ua ntej qhib lub qhov dej txias qhov hluav taws xob ntawm cov khoom siv hluav taws xob graphite, thiab tom qab ntawd maj mam qhib lub qhov dej txias hauv lub valve los xyuas seb lub ntsuas qhov ntsuas siab puas nyob hauv qhov qub. Tom qab ntawd raws li cov txheej txheem yuav tsum tau, siv cov dej txias inlet valve los kho qhov ntws ntawm cov dej txias kom ua tiav cov txiaj ntsig zoo tshaj plaws. Hauv kev siv, qhov sib txawv ntawm qhov kub thiab txias (5 degrees) yuav tsum tau tswj raws li cov yam ntxwv ntawm cov dej txias kom tiv thaiv qhov ntsuas kub ntawm graphite heat exchanger. Yog tias cov dej txias ntawm graphite heat exchanger qis dua 0 degrees, lwm qhov nruab nrab ntawm cov khoom siv hluav taws xob yuav tsum raug cais tawm ntawm lub ntiaj teb sab nraud kom tiv thaiv cov dej hauv qhov nqus cua los ntawm kev khov. Thaum yuav tsum tau nres tsheb mus ntev, thov siv nitrogen los yog compressed cua los nias tawm cov dej txias hauv lub raj cua kub exchanger los tiv thaiv kev nthuav dav. Los yog kaw cov dej txias hauv qhov hluav taws xob thiab qhov hluav taws xob, thiab qhib qhov chaw nres nkoj kom tsis txhob ntim ntim. Yog tias cov khoom siv hluav taws xob graphite tau siv rau kev sib pauv kua-kua, lwm qhov kawg ntawm cov kua nruab nrab yuav tsum tau nias tib lub sijhawm, thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob yuav tsum tau npaj zoo tib lub sijhawm. Kev cais tawm sab nraud thiab lwm yam kev ua haujlwm tiv thaiv corrosion. Yog tias qhov kev sib pauv cua sov ntawm cov khoom siv hluav taws xob graphite tsis zoo, thov qhib qhov chaw nres nkoj kom tshem tawm cov roj uas tsis yog condensable ua ntej siv lossis ntxuav. Tom qab siv, thov kaw lub qhov dej txias hauv lub valve, ntxuav cov khoom siv hluav taws xob graphite thiab qhov system hauv lub sijhawm, thiab ua kom huv si.
