Xaiv qhov nruab nrab ntws hauv fluoroplastic heat exchangers

Hauv kev tsim cov fluoroplastic heat exchangers, peb thawj zaug yuav tsum tau txiav txim siab cov ntaub ntawv uas yuav tsum tau siv los ua qhov nruab nrab, thiab txiav txim siab seb qhov nruab nrab twg yuav tsum tau siv rau hauv cov txheej txheem ntawm lub plhaub thiab lub raj. Cov hauv paus ntsiab lus uas yuav tsum tau ua raws li hauv kev xaiv yog raws li hauv qab no:

Ua ntej, txhim kho cov hluav taws xob hloov hluav taws xob me me ntawm ob sab ntawm fluoroplastic tshav kub exchanger, kom cov cua sov hloov coefficients ntawm ob sab ntawm lub tshav kub hloov chaw nyob ze.

Qhov thib ob, rau cov tshuaj lom los yog gaseous xov xwm, fluoroplastic tshav kub exchangers yuav tsum tsis txhob xau thiab tshwj xeeb yuav tsum tau them rau lawv sealing. Lub sealing tsis yog tsuas yog txhim khu kev qha, tab sis kuj yooj yim thiab yooj yim. Seb puas siv fluoroplastic heat exchangers yog ib rooj plaub tshwj xeeb.

Thib peb, kev ntsuas cov kav dej thiab cov plhaub yuav tsum tau ntxuav, descaled, corrosion-resistant, tswj, thiab kho kom ntau li ntau tau kom ntseeg tau tias kev ua haujlwm.

Fourthly, for the medium of fluoroplastic heat exchangers, if the flow rate is small and the fluid viscosity in the shell is generally appropriate, as turbulence can be achieved when Re>100 nyob rau hauv lub plhaub. Tab sis qhov no tsis yog qhov tseeb, vim tias qhov kev poob qis tso cai rau cov kua dej ntws mus rau hauv cov kav dej, thiab kev siv cov yeeb nkab ntau yam kuj tuaj yeem ua rau cov coefficients ntawm qhov kub siab dua.

Thib tsib: Vim muaj ntau hom cua sov, qhov thermal stress ntawm cov hlab thiab cov plhaub ntawm fluoroplastic heat exchangers yuav tsum raug txo. Los ntawm qhov kev xav no, downstream yog ntau dua countercurrent vim tias qhov hluav taws xob kub siab tshaj qhov nruab nrab countercurrent. Cov dej txias txias thiab cov dej kub kub yog concentrated thaum kawg, thiab qhov qis dua yog concentrated ntawm lwm qhov kawg, uas yog qhov sib txawv thermal stresses tshwm sim los ntawm contraction ntawm ob qho kawg.

Thib rau: Hauv cov ntaub ntawv ntawm fluoroplastic heat exchangers, cov hlau muaj txiaj ntsig yuav tsum raug zam kom txo cov nqi.

Cov yam ntxwv ntawm phaj kub exchangers

Nyob rau hauv xyoo tas los no, cov yam ntxwv ntawm cov phaj kub exchangers yog lub teeb yuag, me me hneev taw, tsis tshua muaj peev txheej, siab kub pauv efficiency, hloov tau yooj yim sib dhos, yooj yim expansion thiab contraction, thiab yooj yim disassembly. Maj mam nrov nyob rau hauv ntau yam kev lag luam thiab cov txheej txheem. Tab sis vim qhov me me ntws hla ntu ntawm lub phaj kub exchanger. Tom qab scaling, nws yog ib qho yooj yim los thaiv thiab txo lub tshav kub hloov efficiency ntawm lub phaj kub exchanger, yog li cuam tshuam rau kev ruaj ntseg ntawm cov khoom thiab cov kev siv ntawm cov neeg siv. Yog li ntawd, kev ntxuav ntawm lub phaj kub exchanger tau daws los tiv thaiv kev tsim ntawm nplai. 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 xyuas dej zoo suav nrog qhov tsis ua haujlwm ntawm cov dej muag muag, calcium thiab magnesium carbonate. Tom qab lub thermal decomposition ntawm calcium carbonate thiab magnesium hydroxide, dej 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. Qhov no cuam tshuam rau kev ua tau zoo ntawm kev hloov hluav taws xob.
