Cov yam ntxwv ntawm electrothermal tube phaj kub exchangers

Cov yam ntxwv ntawm electrothermal tube phaj kub exchangers

Nyob rau hauv xyoo tas los no, cov yam ntxwv ntawm phaj kub exchangers yog lub teeb yuag, me me hneev taw, tsis tshua muaj peev xwm, siab kub exchanger efficiency, hloov tau yooj yim sib dhos, yooj yim expansion, thiab yooj yim disassembly. Nws yog maj mam nrov nyob rau hauv ntau yam kev lag luam thiab cov txheej txheem. Txawm li cas los xij, vim qhov me me ntws hla ntu ntawm phaj kub exchangers. Tom qab scaling, nws yog ib qho yooj yim los thaiv thiab txo cov tshav kub hloov efficiency ntawm lub phaj kub exchanger, yog li cuam tshuam rau kev nyab xeeb ntawm cov khoom thiab cov kev siv ntawm cov neeg siv. Yog li ntawd, kev ntxuav ntawm lub phaj kub exchanger yog daws thiab qhov tsim ntawm nplai yog tiv thaiv. Nws yuav dhau los ua qhov teeb meem tseem ceeb los xyuas kom muaj kev nyab xeeb ntawm kev tsim khoom thiab kev lag luam kev lag luam. Kev siv cov phaj kub exchangers. Vim kev ua haujlwm tsis raug ntawm cov khoom siv kho dej. Cov txheej txheem tswj dej zoo, softened dej txhaj tshuaj tsis ua hauj lwm, calcium thiab magnesium carbonate, dej tom qab thermal decomposition ntawm calcium carbonate thiab magnesium hydroxide, tsim ib daim ntawv cog lus ntawm lub tshav kub ntawm lub tshav kub exchanger, tsim scale. Vim tsis zoo thermal conductivity, cov cua kub hloov efficiency ntawm lub tshav kub exchanger txo, uas ua rau muaj kev puas tsuaj loj ntawm tshav kub zog. Li no cuam tshuam cov nyhuv ntawm cov cua sov hloov.

Nyob rau hauv lub tshav kub exchanger, feem ntau muaj ob hom kev txheeb ze ntawm cov kua: pem hauv ntej ntws thiab rov qab ntws. Thaum qis qis, qhov kub ntawm qhov sib txawv ntawm ob cov kua dej ntawm qhov nkag yog qhov loj tshaj plaws, maj mam txo qis raws cov cua kub hloov mus rau qhov chaw, thiab qhov kub qis tshaj ntawm qhov hluav taws xob. Nyob rau ntawm lub tshav kub hloov lwm lub tsev, qhov kub thiab txias faib ntawm ob lub kua yog zoo li qub. Thaum lub qhov hluav taws xob thiab qhov hluav taws xob ntsuas kub ntawm cov dej txias thiab kub tau txiav txim siab, thiab tsis muaj qhov hloov pauv ntawm ob cov kua dej, qhov nruab nrab kub qhov sib txawv ntawm cov dej ntws ntws qis yog qhov tsawg kawg nkaus tus nqi, thiab qhov nruab nrab kub qhov sib txawv ntawm cov dej ntws ntws yog tus nqi siab tshaj plaws.

Nyob rau hauv tib lub tshav kub hloov lwm lub tsev, qhov rov qab tam sim no tuaj yeem nce qhov sib txawv ntawm qhov nruab nrab kub thiab txo qhov kub ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob; Yog tias qhov chaw hloov hluav taws xob tsis tu ncua, kev siv cov cua sov lossis cov kua dej txias tuaj yeem txo qis thaum siv cov dej ntws tawm. Cov qub tuaj yeem txuag cov nqi khoom siv, thaum tom kawg tuaj yeem txuag cov nqi khiav lag luam, yog li kev sib pauv cua sov yuav tsum tau siv ntau li ntau tau hauv kev tsim lossis siv ntau lawm. Nyob rau hauv cov txheej txheem ntawm kev hloov hluav taws xob, txo qhov thermal tsis kam ntawm phab ntsa kub exchanger yog ib qho teeb meem tseem ceeb los txhim kho cov cua sov coefficient. Cov kua dej ua yeeb yaj kiab feem ntau yog los ntawm phab ntsa daig ntawm ob sab ntawm lub tshav kub hloov chaw (hu ua ciam txheej), uas tsim cov txheej av ntawm ob sab ntawm phab ntsa. Lub tshav kub exchanger siv rau hlau phab ntsa thermal kuj yog me me.
