Plhaub thiab raj kub exchangersyog dav siv nyob rau hauv tshuaj, roj av, fais fab kev lag luam, thiab HVAC industries rau lawv cov kev cia siab rau siab, loj tshav kub hloov chaw, thiab adaptability rau siab thiab kub tej yam kev mob. Txawm li cas los xij, yam xws li fouling, kev faib tsis raug, thiab cov qauv tsim tsis tsim nyog feem ntau ua rau txo qis kev hloov pauv hluav taws xob, nce kev siv hluav taws xob thiab cov nqi ua haujlwm. Raws li cov kws tshaj lij kev tsim khoom ntawm cov khoom siv hluav taws xob sib pauv, GNEE nthuav qhia cov tswv yim los txhim kho cov cua kub hloov pauv ntawm lub plhaub thiab lub raj cua kub exchangers, pab cov tuam txhab ua haujlwm kom zoo dua qub thiab txo cov nqi.
1. Txhim kho cov kua dej ntws zoo
Lub tshav kub hloov efficiency ntawm lub plhaub thiab lub raj kub exchangers yog ze ze rau lub xeev ntws ntawm cov kua. Turbulent flow tuaj yeem txhim kho cov cua sov hloov pauv piv rau laminar ntws, vim nws txo qhov tuab ntawm cov ciam teb txheej thiab txhawb kev sib xyaw ua kua.
Ib txoj hauv kev zoo yog los kho tus nqi ntws hauv qhov tsim nyog. Kev nce tus nqi ntawm lub plhaub- sab lossis lub raj - sab dej tuaj yeem hloov cov dej laminar ntws mus rau turbulent flow, tab sis nws yog ib qho tsim nyog kom tsis txhob muaj kev poob siab ntau uas yuav ua rau muaj zog siv zog. Lwm txoj hauv kev yog txhawm rau txhim kho cov khoom ua kom zoo. Rau lub raj sab, ntxig cov ntaub nplaum, cov hlua khi, lossis cov khoom sib xyaw zoo li qub tuaj yeem cuam tshuam cov ciam teb txheej thiab txhim kho cov dej turbulence. Rau lub plhaub sab, ntxiv baffle daim hlau (xws li segmental baffles, helical baffles) tuaj yeem ua kom zoo dua cov dej ntws, tiv thaiv qhov chaw tuag, thiab txhim kho cov dej sib xws. Helical baffles, tshwj xeeb tshaj yog, tuaj yeem txo lub plhaub- sab siab poob thaum txhim kho cov cua sov, ua rau lawv haum rau siab - kev ua haujlwm tau zoo.
2. Tswj Fouling thiab khaws cov khoom tsis tu ncua
Fouling yog ib qho tseem ceeb ntawm kev cuam tshuam kev hloov hluav taws xob. Thaum lub sijhawm ua haujlwm, impurities, nplai, thiab cov khoom siv corrosion hauv cov kua dej yuav tso rau ntawm phab ntsa ntawm lub raj thiab lub plhaub- sab saum toj, tsim cov txheej txheem thermal uas thaiv cov cua sov. Raws li kev lag luam cov ntaub ntawv, fouling tuaj yeem txo cov kev hloov pauv hluav taws xob los ntawm 10-30% lossis ntau dua lub sijhawm.
Txhawm rau tswj fouling, ua ntej, ua ntej - kho cov kua dej (xws li pom, muag muag, lossis ntxiv cov tshuaj tiv thaiv- cov tshuaj tua kab) kom txo cov ntsiab lus ntawm impurities thiab scaling Cheebtsam. Qhov thib ob, ua haujlwm tu thiab tu tsis tu ncua. Rau lub teeb fouling, tshuaj ntxuav (siv cov kua qaub los yog alkali daws) tuaj yeem txais yuav; rau qhov hnyav fouling, kev tu txhua yam (xws li siab - lub tshuab nqus dej twj tso kua mis, lub raj txhuam txhuam) yog qhov zoo dua. Tsis tas li ntawd, kev saib xyuas qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab qhov kub ntawm lub sijhawm tuaj yeem pab tshawb xyuas cov teeb meem fouling thaum ntxov thiab ntsuas raws sijhawm. GNEE pom zoo kom tsim ib txoj kev npaj kho tus kheej raws li kev ua haujlwm tiag tiag ntawm cov khoom siv hluav taws xob kom ntseeg tau tias kev ua haujlwm tau zoo ntev -.
3. Xaiv cov khoom siv hluav taws xob hloov hluav taws xob uas tsim nyog
Cov khoom ntawm lub cev ntawm cov khoom siv hluav taws xob hloov hluav taws xob (xws li thermal conductivity, lub peev xwm tshwj xeeb, thiab viscosity) ncaj qha cuam tshuam rau kev hloov hluav taws xob. Xaiv qhov nruab nrab nrog cov thermal conductivity thiab cov peev txheej tshwj xeeb tuaj yeem txhim kho cov cua sov hloov. Piv txwv li, hauv cov txheej txheem kev lag luam, hloov qis - cov xov xwm ua haujlwm tau zoo nrog siab - cov roj hloov hluav taws xob los yog cov khoom ua kom txias tuaj yeem txhim kho cov txiaj ntsig kev sib hloov cua sov.
Lub caij no, xaiv cov khoom siv raj zoo yog qhov tseem ceeb heev. Cov raj ua los ntawm cov ntaub ntawv uas muaj thermal conductivity (xws li tooj liab, txhuas, los yog titanium alloys) muaj kev ua tau zoo ntawm cov cua kub zoo dua li cov pa roj carbon steel. Rau corrosive ua hauj lwm tej yam kev mob, titanium alloy los yog stainless hlau hlab yuav tsis tsuas tiv thaiv corrosion, tab sis kuj muaj zoo thermal conductivity, tsis txhob ua hauj lwm degradation los ntawm corrosion. GNEE muab cov kev pabcuam xaiv cov khoom siv raws li qhov nruab nrab cov yam ntxwv thiab kev ua haujlwm ntawm cov neeg siv khoom kom ua kom cov cua sov ua haujlwm zoo tshaj plaws.
4. Txhim kho tus qauv tsim
Tsim nyog tus qauv tsim yog lub hauv paus rau kev ua kom muaj cua sov hloov mus rau qhov zoo. Ua ntej, optimize lub raj pob layout. Qhov kev npaj ntawm cov hlab ntsha (xws li daim duab peb sab, square, lossis rotated square layout) cuam tshuam rau qhov khiav ceev thiab qhov chaw tshav kub. Daim duab peb sab layout muaj ib lub raj me me thiab loj dua tshav kub hloov chaw rau ib chav tsev ntim, uas yog haum rau siab - efficiency tshav kub hloov scenarios. Qhov thib ob, kho lub raj ntev thiab txoj kab uas hla. Kev ua kom lub raj ntev tuaj yeem ua rau thaj tsam hloov pauv cua sov, tab sis nws yuav tsum sib npaug ntawm qhov siab poob; txo lub raj txoj kab uas hla tuaj yeem txhim kho qhov khiav nrawm thiab txhim kho cov cua sov hloov coefficient, tab sis nws yuav tsum xav txog qhov kev pheej hmoo ntawm fouling thiab blockage.
Tsis tas li ntawd, kev ua kom zoo ntawm lub plhaub- sab hauv thiab qhov hluav taws xob cov qauv, xws li ntxiv cov khoom xa tawm los yog cov khoom ntim khoom, tuaj yeem zam qhov tsis sib xws thiab txhim kho kev siv tus nqi ntawm qhov chaw hloov hluav taws xob. GNEE's R & D pab pawg sib koom ua ke kev simulation thev naus laus zis los muab cov txheej txheem tsim qauv tsim rau tus kheej rau cov neeg siv khoom, kom ntseeg tau tias cov khoom siv hluav taws xob ua kom tiav qhov zoo tshaj plaws ntawm kev hloov hluav taws xob thiab kev siv hluav taws xob.
5. Txais cov thev naus laus zis thev naus laus zis thev naus laus zis
Nrog rau txoj kev loj hlob ntawm tshav kub hloov tshuab, ntau yam kev txhim kho thev naus laus zis tau siv rau lub plhaub thiab lub raj cua kub exchangers. Piv txwv li, siv cov raj finned (xws li qis- finned tubes, siab - finned tubes) tuaj yeem ua rau thaj chaw hloov hluav taws xob ntau ntxiv, tshwj xeeb tshaj yog tsim rau cov xwm txheej uas qhov kub hloov pauv coefficient ntawm ib sab dej qis dua li lwm qhov. Laser nto texturing thev naus laus zis tuaj yeem ua cov micro-grooves lossis micro-protrusions ntawm lub raj nplaim, txo cov ciam txheej tuab thiab txhim kho cov cua sov.
Tsis tas li ntawd, daim ntawv thov ntawm theem hloov pauv hloov hluav taws xob los yog cov yeeb nkab cua sov thev naus laus zis hauv lub plhaub thiab lub raj cua kub exchangers tuaj yeem txhim kho kev hloov hluav taws xob ntxiv. Cov thev naus laus zis siab tshaj no pab cov lag luam ua tiav kev txuag hluav taws xob thiab txo qis emission thaum txhim kho kev tsim khoom.

Kev txhim kho cov hluav taws xob hloov hluav taws xob ntawm lub plhaub thiab lub raj xa hluav taws xob yuav tsum tau ua ke ntawm kev ua haujlwm zoo, kev saib xyuas tsis tu ncua, tsim qauv tsim nyog, thiab kev siv tshuab siab heev. Los ntawm kev ua raws li cov txheej txheem saum toj no, cov tuam txhab tuaj yeem txo cov kev siv hluav taws xob zoo, txo cov nqi ua haujlwm, thiab txhim kho kev tsim khoom. Raws li tus kws tshaj lij kev lag luam ntawm lub plhaub thiab lub raj xa hluav taws xob, GNEE muaj kev paub dhau los hauv R & D, ntau lawm, thiab kev hloov kho.
