Qhov ntau ntawm kev siv phaj kub exchangers yog dav heev, yog li yuav ua li cas los txhim kho kev ua tau zoo ntawm cov phaj kub exchangers hauv kev siv? Cia peb saib luv luv hauv qab no.
1. Vim yog lub ripple ntawm lub phaj kub exchanger, cov kua yuav tsim turbulence ntawm ib tug me me khiav tus nqi, uas ua rau ib tug ntau dua nto tshav kub hloov coefficient. Qhov chaw tshav kub hloov pauv coefficient yog cuam tshuam nrog cov qauv geometric ntawm lub phaj ripple thiab lub xeev ntws ntawm qhov nruab nrab. Lub waveform ntawm lub phaj muaj xws li herringbone, ncaj, kheej kheej, thiab lwm yam. Tom qab xyoo ntawm kev tshawb fawb thiab kev sim, nws tau pom tias herringbone daim hlau nrog ib daim duab peb sab corrugated cross-section muaj ib tug ntau dua nto tshav kub hloov coefficient, thiab lub kaum sab xis loj ntawm lub corrugations, qhov siab dua qhov ntws tawm ntawm qhov nruab nrab hauv qhov sib txuas phaj ntws channel, thiab qhov ntau dua qhov kub hloov pauv coefficient.
Tus yuam sij kom txo cov thermal tsis kam ntawm fouling txheej nyob rau hauv lub tshav kub exchanger yog los tiv thaiv phaj fouling. Thaum lub thickness ntawm lub phaj fouling yog 1 hli, lub tshav kub hloov coefficient txo los ntawm 10%. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas cov dej zoo ntawm ob sab kub thiab txias ntawm cov khoom siv hluav taws xob los tiv thaiv phaj fouling thiab tiv thaiv impurities los ntawm adhering rau daim hlau hauv dej. Qee chav cua sov ntxiv cov tshuaj rau cov cua sov nruab nrab los tiv thaiv dej tub sab thiab corrosion ntawm cov khoom hlau. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau cov dej zoo thiab cov nplaum uas tuaj yeem ua rau impurities kom paug cov phaj kub exchanger. Yog tias muaj cov kua dej tsis huv hauv dej, yuav tsum siv lub lim dej tshwj xeeb rau kev kho mob. Thaum xaiv tus neeg sawv cev, nws raug nquahu kom xaiv cov tsis muaj kuab tshuaj.
3. Cov khoom siv ntawm lub phaj tuaj yeem yog stainless hlau, titanium alloy, tooj liab alloy, thiab lwm yam. Stainless hlau muaj thermal conductivity zoo, nrog rau thermal conductivity ntawm li 14.4 W / (m • K), siab zog, zoo stamping kev ua tau zoo, thiab tsis yooj yim oxidized. Nws tus nqi qis dua li titanium thiab tooj liab alloys, thiab nws feem ntau yog siv rau hauv cov cua sov engineering, tab sis nws lub peev xwm los tiv thaiv chloride ion corrosion tsis zoo.
