Rau cov phaj kub exchangers, nyob rau hauv kev tsim thiab siv cov txheej txheem yuav ib txwm ntsib cov teeb meem ntawm tsis tshua muaj efficiency ntawm phaj tshav kub exchangers, uas muaj xws li ib tug xov tooj ntawm yam tseem ceeb, los mus txiav txim, los txhim kho lub tshav kub hloov efficiency ntawm phaj kub exchangers, los ntawm lub tsim kev pom, plaub lub ntsiab lus hauv qab no yog qhov tseem ceeb tshaj plaws:
1, Txhim kho lub tshav kub hloov coefficient ntawm lub phaj
Raws li cov phaj kub exchanger corrugation tuaj yeem ua rau cov kua hauv qhov me me khiav nrawm (Reynolds tus naj npawb ntawm 150), yog li koj tuaj yeem tau txais qhov siab dua qhov kub hloov coefficient, qhov kub hloov pauv coefficient thiab cov qauv geometric ntawm cov phaj corrugation thiab cov flow xeev ntawm qhov nruab nrab. Lub waveform ntawm lub phaj muaj xws li herringbone, tiaj tus, kheej kheej, thiab lwm yam.
2, Txo cov thermal tsis kam ntawm cov av txheej
Tus yuam sij kom txo cov thermal tsis kam ntawm cov cua kub exchanger fouling txheej yog los tiv thaiv phaj fouling. Phaj fouling thickness ntawm 1 hli, lub tshav kub hloov coefficient yog txo los ntawm 10 feem pua. Yog li ntawd, yuav tsum tau ua tib zoo saib xyuas cov dej zoo ntawm ob sab ntawm cov khoom siv hluav taws xob kub thiab txias kom tiv thaiv cov phaj scaling, thiab tiv thaiv kev sib txuas ntawm cov khib nyiab hauv dej ntawm lub phaj.
3, Kev siv lub siab thermal conductivity phaj
Cov khoom siv phaj tuaj yeem xaiv los ntawm austenitic stainless hlau, titanium alloy, tooj liab alloy, thiab lwm yam. Stainless hlau muaj cov thermal conductivity zoo, thermal conductivity ntawm li 14.4 W / (m - K), siab zog, zoo stamping kev ua tau zoo, tsis yooj yim rau oxidized. , tus nqi qis dua titanium alloy thiab tooj liab alloy, feem ntau siv rau hauv cov cua sov engineering, tab sis nws lub peev xwm los tiv thaiv corrosion ntawm chloride ions tsis zoo.
4, Txo cov thickness ntawm lub phaj
Tus tsim thickness ntawm lub phaj tsis muaj dab tsi ua nrog nws cov corrosion kuj, thiab lub siab-bearing peev xwm ntawm lub tshav kub exchanger. Phaj thickness, tuaj yeem txhim kho lub peev xwm ntawm cov khoom siv hluav taws xob. Kev siv herringbone phaj ua ke, daim hlau nyob ib sab yog inverted rau ib leeg, corrugated kev sib cuag nrog ib leeg, tsim ib tug loj ceev, uniformly faib fulcrum, phaj kaum sab xis solitaire L thiab ntug sealing qauv tau maj mam txhim kho, kom lub phaj kub exchanger muaj. ib tug zoo siab-bearing muaj peev xwm.
