Rationality thiab efficiency ntawm thermal zog siv nyob rau hauv kev lag luam kev lag luam tuaj yeem suav nrog cov ntsiab lus tseem ceeb uas muaj kev cuam tshuam ncaj qha rau kev txiav txim siab lub tswv yim ntawm cov cuab yeej siv thev naus laus zis thiab cov khoom siv rov ua dua tshiab ntawm txhua lub lag luam. Kev ntseeg tau, kev ua tau zoo, muaj kev lees paub thiab kev pabcuam niaj hnub no yog cov ntsiab lus tseem ceeb ntawm kev lag luam kev vam meej thiab kev vam meej ntawm txhua tus neeg koom nrog kev lag luam kev sib raug zoo.
Thaum yuav cov khoom siv tshiab, txhua lub koom haum raug coj los ntawm cov txheej txheem saum toj no. Lub plhaub zoo thiab lub raj cua kub exchangers yog ib yam khoom siv tau zoo thiab kev lag luam. Niaj hnub no, qhov tseem ceeb ntawm cov khoom siv no rau kev lag luam ntawm ib qho profile thiab kev taw qhia tsis yog qhov tsis ntseeg. Tam sim no, plhaub-thiab-tube kub exchangers feem ntau yog siv nyob rau hauv petrochemical, tshuaj thiab zaub mov industries, vaj tse thiab cov kev pab cuam nyob rau hauv lub zej zog thiab lub zog kev lag luam.
Pom pom, ci ntsa iab ntawm cov kev daws teeb meem tshiab thiab kev lag luam, uas muaj ntau yam zoo dua li cov khoom siv tsis siv neeg, tsis ntev los no tau nyiam ntau thiab ntau cov lag luam los ntawm ntau yam kev lag luam hauv lub tebchaws. Tom qab tag nrho, lub plhaub-thiab-lub raj cua kub exchangers tuaj yeem txo qhov kev siv ntawm cov khoom siv cua sov, uas muaj txiaj ntsig zoo rau cov nqi tsim khoom thiab, yog li ntawd, ntawm nws tus nqi kawg. Thiab qhov no yog qhov tseem ceeb heev hauv kev lag luam niaj hnub no nrog lawv cov xwm txheej ntawm kev sib tw hnyav.
Shell-and-tube heat exchangers yog cov khoom siv uas cov txheej txheem ntawm kev sib pauv cua sov ntawm ntau yam kev tshaj tawm ua haujlwm tshwm sim (tsis hais txog lawv cov kev qhia tshwj xeeb thiab lub zog lub zog). Raws li txoj cai, cov khoom siv no ua haujlwm ntawm cov cua sov, evaporators, condensers, pasteurizers, deaerators, economizers, thiab lwm yam.
Shell-and-tube heat exchangers tuaj yeem muaj lub hom phiaj thev naus laus zis sib txawv thiab siv los tsim ntau yam ntawm cov profiles. Qhov ntau ntawm lawv daim ntawv thov niaj hnub no yog txawv txawv. Lub plhaub-thiab-lub raj cua kub exchanger, lub ntsiab yam ntxwv ntawm uas yog bundles ntawm cov hlab nrog daim phiaj, ib tug casing, ceg kav dej thiab npog, yuav siv tau raws li ib tug chav tsev nyob rau hauv uas hloov thermal zog yog lub ntsiab technologies txheej txheem, los yog raws li ib tug reactor nyob rau hauv uas sib pauv cua sov yog tshwj xeeb tshaj yog ib tug auxiliary xwm.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub plhaub thiab lub raj kub hloov pauv yog ua raws li cov txheej txheemKev hloov hluav taws xob los ntawm qhov nruab nrab txav ntawm kev kub ceev hauv cov kav dej me me mus rau qhov nruab nrab circulating hauv lub plhaub. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kom sov, cov khoom siv no feem ntau nruab nrog cov baffles tshwj xeeb hauv cov raj thiab lub plhaub qhov chaw.
Plhaub thiab lub raj cua kub exchangers muaj nyob rau hauv ntsug, kab rov tav los yog inclined spatial orientation (nyob ntawm cov txheej txheem yuav tsum tau thiab yooj yim ntawm installation). Xws li cov chav nyob yog ib qho kev hloov pauv tag nrho rau cov phaj kub hloov pauv, piv nrog cov uas, txawm hais tias lawv muaj kev ua haujlwm qis dua ntawm kev hloov hluav taws xob, lawv muaj cov txheeb ze ntawm kev tsim qauv, nrog rau cov nqi qis, uas tuaj yeem yog qhov kev txiav txim siab thaum xaiv. cov khoom ntawd.
