I. Cov kua dej- cuam tshuam nrog (cov ntsiab lus tseem ceeb ntawm kev hloov hluav taws xob hloov hluav taws xob)
Cov kua dej yog cov cab kuj ntawm cov cua kub hloov hauv lub tshav kub exchanger. Nws tus kheej cov yam ntxwv thiab lub xeev ntws ncaj qha txiav txim siab qhov kev hloov pauv hluav taws xob, uas yog qhov tseem ceeb uas yuav tsum tau lees paub thaum xaiv cov khoom siv hluav taws xob xa tawm.
1. Dej tshaj tawm: ib qho tseem ceeb sib txawv uas cuam tshuam rau lub tshav kub hloov coefficient
Flow velocity yog ib qho tseem ceeb tshaj plaws uas cuam tshuam rau lub tshav kub hloov coefficient; Qhov siab dua qhov nrawm dua, qhov ntau dua ntawm cov dej turbulence, lub thinner lub convective tshav kub hloov ciam txheej, thiab yog li ntawd, qhov siab dua qhov kub hloov coefficient thiab efficiency. Piv txwv li, nyob rau hauv lub turbulent flow regime-feem ntau ntawm kev nrawm li ntawm kwv yees li 0.1 mus rau 1.0 m / s- phaj kub exchangers tuaj yeem ua tiav cov coefficients siab. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev nce siab tshaj plaws ua rau muaj kev nce ntxiv hauv quadratic hauv kev poob siab. Yog li ntawd, qhov sib npaug yuav tsum raug ntaus ntawm kev hloov pauv hluav taws xob thiab kev siv hluav taws xob ua haujlwm; Thaum lub sij hawm xaiv txheej txheem, tus tsim yuav tsum tau optimized los ntawm kev coj mus rau hauv tus account qhov tseeb tso cai rau poob siab yuav tsum tau.
2. Dej lub cev muaj zog: txiav txim siab lub zog ntawm lub hauv paus kev sib hloov cua sov.
Lub cev lub cev ntawm cov kua dej-xws li thermal conductivity, tshwj xeeb tshav kub muaj peev xwm, viscosity, thiab ntom- ncaj qha cuam tshuam rau lub convective heat transfer coefficient. Tshwj xeeb, ntau dua thermal conductivity thiab tshwj xeeb tshav kub muaj peev xwm ua rau muaj peev xwm hloov tau ntau dua; Piv txwv li, dej, nrog rau cov thermal conductivity ntawm kwv yees li 0.6 W / (m·K) thiab ib tug tshwj xeeb tshav kub muaj peev xwm ntawm txog 4.2 kJ / (kg·K), nyob rau hauv qeb ntawm cov kua nrog superior kub hloov mus rau lwm yam xov xwm. Conversely, ntau dua viscosity ua rau kom cov kua ntws tsis kam, txo turbulence, thiab thiaj li txo cov tshav kub hloov efficiency; Piv txwv li, thaum cov tshuaj tiv thaiv kab mob xws li ethylene glycol ntxiv rau hauv dej, cov thermal conductivity txo qis thaum lub viscosity nce, uas ua rau txo qis ntawm tag nrho cov tshav kub hloov coefficient.
3. Cov kua dej kub sib txawv: cov tub ntxhais tsav tsheb ntawm cov cua sov hloov
Qhov kub thiab txias sib txawv ntawm cov kua dej kub thiab txias (tshwj xeeb tshaj yog logarithmic txhais tau tias qhov kub thiab txias sib txawv) yog lub zog tsav rau kev hloov cua sov. Qhov ntau dua qhov sib txawv ntawm qhov kub thiab txias, qhov kub hloov pauv sai dua thiab qhov ua tau zoo ntawm cov khoom siv hluav taws xob hloov pauv tau zoo dua.Muab cov txheej txheem yuav tsum tau ua tiav, tsim nyog nce qhov kub ntawm qhov kub ntawm qhov nruab nrab los yog txo qhov inlet kub ntawm qhov txias qhov nruab nrab tuaj yeem ua kom qhov kub thiab txias sib txawv; conversely, me me qhov sib txawv ntawm qhov kub thiab txias yuav ua rau tsis txaus hloov hluav taws xob hloov hluav taws xob thiab cuam tshuam rau kev sib pauv cua sov. Tsis tas li ntawd, qhov hluav taws xob qhov hluav taws xob sib txawv ntawm cov xov xwm kub thiab txias yuav tsum tau tswj nyob rau hauv qhov tsim nyog kom tsis txhob muaj qhov sib txawv ntawm qhov kub thiab txias ua rau muaj kev ntxhov siab ntau ntxiv ntawm cov khoom siv.
4. Kev huv huv: Kom tsis txhob muaj qhov txo qis hauv kev sib pauv cua sov.
Yog hais tias cov kua muaj impurities, roj, nplai, thiab lwm yam, ib txheej fouling yuav tsim rau ntawm tshav kub exchanger nto. Lub thermal conductivity ntawm fouling yog qis dua li ntawm cov hlau, uas yuav tsim cov thermal kuj tseem ceeb, uas ua rau txo qis hauv cov cua sov hloov coefficient thiab poob ntawm kev sib pauv cua sov.Piv txwv li, cov dej khib nyiab sab channel yog qhov ua rau muaj qhov tsim tawm vim qhov sib txuam ntawm impurities. Txawm tias ib txheej nyias ntawm nplai tuaj yeem cuam tshuam rau kev sib pauv cua sov. Nws yog tsim nyog los ntxuav cov kua impurities tsis tu ncua los yog optimize lub channel tsim kom ncua scale tsim.
II. Khoom yam ntxwv yam ntxwv (txiav txim siab lub tshav kub exchanger foundation peev)
Cov qauv tsim ntawm lub tshuab hluav taws xob hluav taws xob ncaj qha cuam tshuam rau cov dej ntws hauv lub xeev thiab kev siv tus nqi ntawm qhov chaw hloov hluav taws xob. Nws yog qhov tseem ceeb ntawm kev txiav txim siab ntawm cov cuab yeej ua haujlwm ua ntej nws tawm hauv lub Hoobkas thiab tseem yog tus yuam sij rau kev sib tw sib txawv ntawm cov khoom lag luam txawv teb chaws.
1. Thaum tshav kub kub hloov chaw: lub hauv paus guarantee ntawm tshav kub exchanger muaj peev xwm
Qhov loj dua qhov chaw hloov hluav taws xob, qhov ua tiav ntau dua ntawm kev sib cuag ntawm cov kua kub thiab txias, qhov siab dua tag nrho cov hloov hluav taws xob, thiab qhov muaj zog ntawm cov khoom siv hluav taws xob sib txawv. Qhov chaw hloov hluav taws xob tsim hluav taws xob sib txawv heev ntawm ntau hom hluav taws xob sib txawv. Piv txwv li, thaj chaw hloov hluav taws xob hauv ib chav tsev ntim ntawm lub phaj kub hloov pauv tuaj yeem ncav cuag 250-1000㎡/m³, nrog cov qauv compact thiab siab kub hloov chaw siv.Shell- thiab-tube heat exchangers muaj me me tshav kub hloov chaw rau ib chav tsev ntim, ua rau lawv haum rau tsawg -flow-rate kub exchangers scen Thaum xaiv ib tus qauv, qhov chaw hloov hluav taws xob yuav tsum tau ua kom haum raws li qhov xav tau ntawm cov khoom siv cua sov.
2. Thaum tshav kub kub hloov lwm lub tsev qauv: cuam tshuam turbulence siv thiab tshav kub hloov efficiency
Kev tsim cov geometry ntawm lub tshav kub pauv qhov chaw ncaj qha cuam tshuam rau lub xeev ntws thiab turbulence siv ntawm cov kua, thiab yog li lub tshav kub hloov efficiency. Kev siv phaj kub exchangers ua piv txwv, qhov tob corrugation, corrugation lub kaum sab xis, suab, thiab lwm yam tsis muaj corrugated phaj yog qhov tseem ceeb. Herringbone corrugations yog ib qho piv txwv ntawm kev hloov hluav taws xob zoo. Lub corrugations ntawm daim hlau uas nyob ib sab yog nyob rau hauv cov lus qhia, tsim ib tug loj tus naj npawb ntawm cov ntsiab lus sib cuag, uas ob leeg dais siab thiab txhawb turbulence. Qhov tob corrugation feem ntau yog 3-5 mm. Qhov ntau dua qhov tob, qhov muaj zog muaj zog, tab sis lub siab poob ntau dua.Cov fin hom (ncaj fins, corrugated fins) thiab qhov sib txawv ntawm finned tube heat exchangers kuj cuam tshuam rau huab cua-sab tshav kub hloov chaw thiab turbulence. Serrated fins yog tsim nyog rau kev khiav ceev ceev scenarios los txhim kho cua sov hloov.
3. Flow channel tsim: txiav txim siab qhov sib npaug ntawm cov kua dej ntws.
Cov duab, qhov loj me, thiab kev teeb tsa ntawm cov ntws ntws txiav txim siab txoj kev ntws thiab qhov sib xws ntawm cov kua dej hauv cov khoom siv hluav taws xob. Yog hais tias cov dej ntws yog nqaim dhau lawm, kev thaiv thiab kev poob siab ntau yuav zoo li qub; Yog hais tias lawv dav dhau lawm, kev khiav ceev yuav txo qis, turbulence yuav tsis muaj zog, thiab kub pauv efficiency yuav cuam tshuam; Cov dej tsis sib xws yuav ua rau cov kua dej tsis sib xws, uas ua rau tsis sib xws. Tsis tas li ntawd, kev tsim cov naj npawb ntawm cov dej ntws (tube dhau, plhaub dhau) yuav tsum tau ua kom zoo dua qub nrog rau cov kua dej ntws thiab cov kev xav tau poob siab. Hauv kev tsim cov khoom lag luam xa tawm, ob qho tib si kev sib pauv hluav taws xob thiab kev siv hluav taws xob yuav tsum tau txiav txim siab.
4. Kev xaiv cov khoom siv: cuam tshuam rau kev hloov pauv cua sov thiab cov khoom siv lub neej.
Lub thermal conductivity thiab corrosion kuj ntawm cov khoom siv hluav taws xob sib txuas ncaj qha cuam tshuam rau kev hloov hluav taws xob thiab cov khoom siv ruaj khov. Cov thermal conductivity zoo dua ua rau kev hloov pauv sai dua. Cov ntaub ntawv xws li tooj liab, stainless hlau, thiab titanium alloys feem ntau yog siv siab -cov ntaub ntawv thermal conductive. Tooj liab muaj qhov zoo tshaj plaws thermal conductivity tab sis tsis zoo corrosion kuj; titanium alloys muaj zog corrosion kuj thiab tsim nyog rau corrosive media ib puag ncig, tab sis lawv kim dua.Cov khoom tsim nyog yuav tsum tau xaiv raws li cov yam ntxwv ntawm qhov nruab nrab (xws li seb nws puas muaj cov khoom siv corrosive), kev khiav hauj lwm kub thiab siab, kom tsis txhob kub pauv attenuation los yog cov khoom puas vim cov khoom siv tsis zoo.
