I. Kev Sib Piv Ntawm Kev Sib Pauv Thaum Tshav Kub Kub: Plate Heat Exchangers Muaj Qhov Zoo Tshaj Plaws
1. Phaj Thaum tshav kub kub Exchanger: Siab kub Exchanger Efficiency
Lub phaj kub hloov pauv siv cov qauv phaj corrugated, tso cai rau cov kua dej hauv cov kab nqaim kom tsim tau siab - siv turbulence txawm tias tsawg Reynolds tus lej, yog li tshem tawm tag nrho cov teeb meem cuam tshuam txog cov dej hla dhau thiab stagnation.Nws cov hluav taws xob hloov pauv tuaj yeem ncav cuag 1,500–5,500 th tsib npaug ntawm W / (ree) cov pa plhaub-thiab- raj kub exchangers. Tsis tas li ntawd, cov xov xwm txias thiab kub ntws hauv qhov nruj nruj- tam sim no nyob rau hauv tag nrho cov txheej txheem, uas ua rau muaj kev siv siab heev ntawm qhov sib txawv ntawm qhov kub thiab txias; Qhov ntsuas kub ntawm qhov sib txawv tuaj yeem ua rau qis li 1 degree, kom ntseeg tau tias kev sib pauv cua sov ntau dua. Raws li kev khiav hauj lwm sib npaug, qhov no txhais tau tias txo qis kev siv hluav taws xob thiab txo qis hluav taws xob tsawg.
2. Plhaub-thiab-Tube Thaum tshav kub kub Exchanger: Thaum tshav kub kub exchanger efficiency yog nruab nrab mus rau qis.
Hauv lub plhaub - thiab - raj kub exchangers, cov kua dej sib cais los ntawm lub raj sab thiab lub plhaub sab; yog li ntawd, kev sib xyaw ua ke tsis muaj zog, ua rau muaj cov kua dej tuag aav thiab bypass channel. Yog li ntawd, lub tshav kub hloov pauv coefficient feem ntau yog li ntawm 300 txog 1000 W / (m²·℃). Kev siv kev ua haujlwm ntawm qhov kub thiab txias sib txawv ntawm cov xov xwm kub thiab txias yog txwv, nrog cov pa ya davhlau ya nyob twg kub qhov sib txawv tshaj 5 degree. Yuav kom ua tau raws li cov kev xav tau sib npaug, qhov loj dua qhov kub hloov qhov chaw yog qhov tsim nyog, uas ua rau muaj kev siv hluav taws xob ntau dua piv rau cov phaj kub hloov pauv.
II. Kev sib piv ntawm cov qauv thiab cov hneev taw: Plate Heat Exchangers muaj ntau dua thiab sib dua
1. Phaj Thaum tshav kub kub Exchanger: compact loj, hnav, thiab tsawg hneev taw.
Plate heat exchangers feature a highly compact structure, with a heat exchange surface area per unit volume range of 200 mus rau 1000 m² / m³-ntau tshaj ntawm lub plhaub- thiab- cov khoom siv raj. Nrog cov phaj tuab ntawm tsuas yog 0.4 txog 0.8 hli, lawv qhov hnyav tag nrho yog kwv yees li ib -tsib tsib ntawm lub plhaub- thiab- raj kub exchanger ntawm sib npaug specifications. Yuav tsum tsis muaj qhov chaw dav dav, lawv zoo tagnrho rau cov chaw tsim khoom, cov tsev, thiab cov haujlwm me me - nplai kev lag luam uas qhov chaw txwv; Tsis tas li ntawd, lawv ua rau txo qis kev thauj mus los thiab kev teeb tsa tus nqi, muab qhov zoo sib xws rau kev xa khoom txawv teb chaws.
2. Plhaub-thiab-Tube Thaum tshav kub kub Exchanger: Cov ntim loj, loj, thiab nyob hauv qhov loj.
Plhaub-thiab-tube heat exchangers muaj hnyav-cov haujlwm ua haujlwm-xws li lub plhaub, lub hnab ntim, cov ntawv raj, thiab cov baffles- ua rau muaj cov qauv loj thiab loj nrog lub tshav kub pauv qhov ntom ntom ntawm tsuas yog 50–150 m² / m³ Raws li qhov sib txawv ntawm kev sib pauv cua sov, lawv lub cev ntim thiab hneev taw yog ob peb zaug ntau dua li cov phaj- hom hloov hluav taws xob; Tsis tas li ntawd, lawv xav tau kev teeb tsa loj, ruaj ruaj, ua rau cov nqi ntau dua rau kev thauj mus los, hoisting, thiab kev teeb tsa. Yog li ntawd, lawv tsis tsim nyog rau qhov project scenarios nrog txwv los yog compact spatial txwv.
III. Kev sib piv ntawm kev khiav hauj lwm qhov kev hloov kho: Plhaub-thiab-Tube Thaum tshav kub kub Exchangers yog haum rau kev khiav hauj lwm heev
1. Phaj Heat Exchanger: Haum rau cov qauv, kev ua haujlwm me me.
Vim muaj kev txwv los ntawm lawv cov gaskets thiab cov qauv phaj, phaj kub exchangers muaj kev txwv tsis pub muaj qhov kub thiab txias. Lawv cov txheej txheem kev khiav hauj lwm tsis yog feem ntau txwv rau qhov ntsuas kub tsawg dua lossis sib npaug li 180℃thiab siab dua los yog sib npaug li 2.5 MPa. Yog li ntawd, lawv tsuas yog tsim nyog rau cov kua dej huv xwb- xws li cov dej tshiab, roj, thiab cov qauv tsis yog - cov tshuaj lom neeg muaj zog corrosive- thiab yog qhov zoo tshaj plaws rau cov kev ua haujlwm me me uas pom hauv HVAC systems, dej siv cua sov, kev lag luam teeb, khoom noj khoom haus, thiab kev lag luam kev lag luam. Lawv tsis haum rau qhov chaw huab cua uas muaj qhov kub thiab txias, kub siab, lossis cov khoom muaj corrosive heev. Tsis tas li ntawd, lawv cov dej ntws nqaim tuaj yeem ua rau txhaws; Yog li ntawd, kev siv xov xwm uas muaj cov khoom loj lossis cov khoom tsis zoo yog txwv nruj heev.
2. Plhaub-thiab-Tube Heat Exchanger: Haum rau kev ua haujlwm nyuaj uas muaj qhov kub thiab txias.
Lub plhaub-thiab- raj kub exchanger nta lub zog thiab ruaj khov tag nrho- steel qauv, boasting tshwj xeeb tsis kam rau ob qho tib si kub siab thiab kub; Nws muaj peev xwm tiv taus kev ua haujlwm siab tshaj 400℃thiab 10 MPa. Yog li ntawd, nws yog qhov kev xaiv zoo tshaj plaws rau kev lag luam hnyav xws li roj av, chemical engineering, hluav taws xob fais fab, metallurgy, thiab nuclear zog. Cov cuab yeej yog tus cwj pwm los ntawm qhov dav dav ntawm cov dej ntws thiab kev ua siab ntev rau ntau yam xov xwm, ua rau nws sib haum nrog cov kua dej uas muaj sediment, particulates, siab viscosity, los yog impurities tseem ceeb. Nws tsis kam mus fouling thiab clogging yog deb tshaj ntawm cov phaj kub exchangers, qhia tshwj xeeb adaptability rau ntau yam kev khiav hauj lwm tej yam kev mob.
