A plhaub-thiab- raj kub exchangeryog ib hom cua kub exchanger muaj li ntawm ib tug series ntawm raj. Ib txheej ntawm cov hlab nqa cov kua dej kub, thiab lwm lub teeb yog cov dej txias.
Cov hlab yog nyob rau hauv ib lub plhaub cylindrical. Thaum tshav kub kub yog kis los ntawm cov kua dej kub mus rau cov kua dej txias los ntawm cov phab ntsa ntawm lub raj, ua kom muaj kev sib hloov pauv tau zoo.
Lub plhaub-thiab- raj kub exchanger yog ib qho ntawm cov khoom siv hluav taws xob uas nrov tshaj plaws vim nws tso cai rau cov neeg tsim qauv hloov kho kom haum rau ntau yam kev kub ntxhov thiab kub.
Plhaub-thiab-tube heat exchangers feem ntau muab faib ua ob pawg:
Cov khoom siv hauv kev lag luam petrochemical, uas feem ntau ua raws li cov qauv ntawm TEMA (Tubular Exchanger Manufacturers Association)
Pub dej rhaub, hluav taws xob cog condensers, thiab lwm yam., siv hauv kev lag luam fais fab
Tsis hais txog ntawm kev lag luam uas siv cov khoom siv sib txawv, nws muaj qee yam zoo sib xws.
Cov Cheebtsam tseem ceeb ntawm Plhaub-thiab-Tube Heat Exchangers
Pem hauv ntej Header - Cov kua dej nkag mus rau hauv lub raj sab ntawm lub tshav kub exchanger ntawm no. Nws yog qee zaum hu ua lub taub hau ruaj khov. Nws coj cov kua dej nkag mus rau sab raj thiab ua kom muaj kev faib tawm tsim nyog.
Tsheb Header -- Qhov no yog qhov uas cov kua dej sab hauv lub raj tawm ntawm lub tshuab hluav taws xob, lossis rov qab mus rau pem hauv ntej header hauv cov khoom siv hluav taws xob nrog ntau lub raj xa mus. Nws sau cov kua dej ntws tawm thiab ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas cov kua dej kom zoo, tshwj xeeb tshaj yog nyob rau hauv ntau qhov kev tsim qauv.
Tube Bundle - Ua los ntawm cov raj, raj ntawv, baffles, khi pas nrig, thiab lwm yam., nws yog siv los tuav lub raj ntim ua ke. Qhov no yog lub hauv paus ntawm lub tshav kub exchanger qhov twg thaum tshav kub kub hloov mus rau qhov chaw. Baffles tuaj yeem txhim kho kev ntws thiab txhim kho kev sib pauv cua sov.
Plhaub -- Nws muaj cov hlua khi thiab tso cai rau cov cua sov hloov ntawm lub plhaub-sab thiab lub raj-sab kua.
Hom Plhaub tseem ceeb-thiab-Tube Heat Exchangers
Tsau Tube Sheet Thaum tshav kub kub Exchanger
Lub raj xa hluav taws xob ruaj ruaj yog hais txog lub plhaub - thiab - lub raj cua kub exchanger qhov twg cov ntawv raj ntawm ob qho kawg ntawm lub raj txuas txuas txuas nrog lub plhaub los ntawm vuam.
Tom qab lub raj xa ntawv yog welded rau lub plhaub, nws kuj tseem tuaj yeem ua lub flange, uas txuas nrog lub flange channel nrog bolts.
Nws qhov zoo dua yog cov qauv yooj yim, thiab qhov xav tau sab hauv txoj kab uas hla ntawm lub plhaub yog qhov tsawg tshaj plaws nyob rau hauv cov xwm txheej ntawm kev ua kom muaj vaj huam sib luag hloov chaw.
Txawm li cas los xij, nws muaj qhov tsis zoo: thaum muaj qhov sib txawv ntawm qhov kub thiab txias ntawm lub plhaub - sab thiab raj - sab xov xwm, thermal stress loj yuav raug tsim, uas yuav ua rau kev sib koom ua ke ntawm cov hlab thiab cov ntawv raj rub tawm thiab tawg, ua rau cov dej xau lossis cov raj tsis ruaj khov.
Nyob rau tib lub sijhawm, kev saib xyuas thiab lub plhaub- kev tu sab hauv yog tsis yooj yim. Nws yog dav siv nyob rau hauv dav dav tab sis yog txwv los ntawm qhov kub thiab txias sib txawv.
U-tube Thaum tshav kub kub Exchanger
AU-tube heat exchanger yog ib hom plhaub- thiab- raj kub exchanger, feem ntau yog tsim los ntawm cov ntawv raj, lub plhaub, lub raj ntim thiab lwm yam khoom.
Nws cov qauv tsuas muaj ib daim ntawv raj xwb, thiab ob qho kawg ntawm cov khoom siv hluav taws xob sib txuas yog tsau rau ntawm tib lub raj ntawv, uas tuaj yeem nthuav dav thiab cog lus dawb kom tsis txhob muaj kev ntxhov siab thermal.
Lub raj sab ntawm lub tshuab hluav taws xob no siv ob lub- raj- dhau kev tsim, nrog rau txoj kev khiav ntev thiab siab txaus, uas ua rau muaj kev hloov pauv tau zoo.
Lub plhaub sab tuaj yeem kuaj xyuas thiab ntxuav los ntawm rub tawm lub raj ntim.
Txawm li cas los xij, vim qhov kev txwv ntawm cov leeg khoov, qhov kev siv ntawm cov ntawv raj yog qhov tsawg, lub plhaub - sab dej yog qhov luv luv -circuiting, thiab sab hauv - txheej kub pauv cov raj tsis tuaj yeem hloov tau ib zaug puas.
Nws yog qhov tsim nyog rau qee lub sijhawm uas muaj qhov sib txawv ntawm qhov kub thiab txias ntawm lub raj thiab lub plhaub, lossis qhov chaw ntawm lub plhaub sab yog qhov yooj yim rau scaling thiab xav tau kev tu, thiab tshwj xeeb tshaj yog haum rau hauv - raj kho ntawm siab - kub, siab - siab thiab corrosive cov ntaub ntawv.
Floating Head Heat Exchanger
Lub tshuab hluav taws xob lub taub hau ntab muaj tsuas yog ib qho ntawm cov ntawv raj ntawm ob qhov kawg tsau rau lub plhaub, thaum lwm qhov kawg tuaj yeem txav mus los ntawm lub plhaub, uas yog hu ua lub taub hau ntab.
Lub taub hau ntab yog tsim los ntawm cov ntawv ntab ntab ntab, lub nplhaib sib cais, thiab lub taub hau ntab saum taub hau, thiab nws yog qhov sib txuas ua ke. Lub hnab ntim lub raj tuaj yeem rub tawm ntawm lub plhaub.
Lub thermal deformation ntawm lub raj ntim thiab lub plhaub tsis txwv ib leeg, yog li tsis muaj thermal stress yuav raug tsim.
Nws qhov zoo yog tias kev ntxuav ntawm cov hlab thiab hauv cov hlab yog yooj yim, thiab tsis muaj kev ntxhov siab thermal yuav tshwm sim.
Txawm li cas los xij, nws muaj qhov tsis zoo: nws cov qauv yog qhov nyuaj, tus nqi siab dua li cov khoom siv hluav taws xob ruaj khov, cov khoom siv yog loj, thiab cov khoom siv loj. Tsis tas li ntawd, lub hau me me ntawm lub taub hau ntab kawg tsis tuaj yeem kuaj xyuas thaum lub sijhawm ua haujlwm, thiab kev sib khi siab yog xav tau hauv kev tsim khoom.
Nws yog qhov tsim nyog rau qee lub sijhawm uas muaj qhov sib txawv ntawm phab ntsa loj ntawm lub plhaub thiab lub raj ntim, los yog qhov chaw ntawm lub plhaub - sab nruab nrab yog qhov ua rau scaling.
