Yuav ua li cas kho cov thermal zog ntawm cov kua nyob rau hauv ib tug tubular tshav kub exchanger?

Kho cov thermal zog ntawm cov kua hauv lub tubular kub exchanger tuaj yeem ua tau los ntawm cov hauv qab no:
1. Xaiv cov kua dej uas tsim nyog: Thaum xaiv cov kua dej, cov khoom siv thermal xws li thermal conductivity, muaj peev xwm kub, thiab viscosity yuav tsum tau txiav txim siab. Feem ntau hais lus, cov kua dej uas muaj cov thermal conductivity siab, muaj peev xwm ua kom muaj cua sov siab, thiab cov viscosity tsawg muaj qhov ua tau zoo dua cov cua sov.
2. Kho qhov kub ntawm cov kua: Qhov kub ntawm cov kua muaj qhov cuam tshuam loj rau nws cov khoom thermal. Feem ntau hais lus, nce qhov kub ntawm cov kua yuav txo tau nws cov viscosity, txhim khu nws fluidity, thiab yog li txhim kho cov tshav kub hloov efficiency. Txawm li cas los xij, qhov kub thiab txias heev kuj tuaj yeem ua rau thermal stress thiab corrosion teeb meem hauv cov khoom siv, yog li yuav tsum pom qhov sib npaug.
3. Ntxiv cov khoom siv hluav taws xob hloov hluav taws xob: Ntxiv cov khoom siv hluav taws xob hloov mus rau cov kua dej tuaj yeem txhim kho lawv cov thermal conductivity. Txoj kev no tuaj yeem txhim kho kev hloov pauv ntawm cov cua sov ntawm tubular heat exchangers yam tsis tau hloov cov kua hom thiab kub.
4. Hloov lub xeev ntws ntawm cov kua dej: Los ntawm kev hloov lub xeev ntws ntawm cov kua dej (xws li nce ntws nrawm, hloov cov kev taw qhia, thiab lwm yam), nws cov convective heat transfer coefficient tuaj yeem cuam tshuam. Kev nce tus nqi ntws tuaj yeem txhim kho qhov hloov pauv cua sov, tab sis nws kuj ua rau kom lub zog noj ntawm lub twj tso kua mis; Hloov cov kev taw qhia ntws tuaj yeem cuam tshuam rau kev xa tawm hluav taws xob thiab ua kom zoo dua cov nyhuv hloov hluav taws xob.
5. Tsis txhob siv cov kua dej scaling thiab corrosion: Scaling thiab corrosion tsis tsuas yog cuam tshuam cov thermal zog ntawm cov kua, tab sis kuj ua rau cov khoom puas. Yog li ntawd, kev ntsuas tsim nyog yuav tsum tau ua kom tsis txhob muaj dej scaling thiab corrosion, xws li siv cov tshuaj tiv thaiv scaling, preservatives, thiab lwm yam.
6. Kev tu thiab tu tsis tu ncua: kev tu thiab tu cov tubular cua sov hloov pauv tuaj yeem tswj tau lawv cov kev ua haujlwm zoo ntawm cov cua sov. Kev ntxuav tuaj yeem tshem tawm cov av thiab cov khib nyiab los ntawm qhov chaw ntawm cov khoom siv, rov ua kom nws cov cua sov hloov pauv; Kev saib xyuas tuaj yeem tshawb xyuas thiab kho cov cuab yeej siv rau kev puas tsuaj thiab xau, kom ntseeg tau tias nws ua haujlwm li qub.
