Kev ua tau zoo ntawm cov tshuaj tsuag cua sov exchanger:

Kev ua tau zoo ntawm cov tshuaj tsuag cua sov exchanger:

Cov khoom siv hluav taws xob zoo li no kho cov khoom siv hluav taws xob sib hloov hauv cov kab ntawm cov ncej steel, cov kua dej kub ntws hauv cov raj, thiab cov dej txias yog sib npaug los ntawm cov khoom siv tshuaj tsuag los ntawm saum toj no, yog li nws tseem hu ua spray cooler. Sab nraud ntawm cov tshuaj tsuag cua kub exchanger raj yog ib txheej ntawm cov kua zaj duab xis nrog ib tug ntau dua degree ntawm turbulence, thiab cov cua sov coefficient sab nraum lub raj yog loj npaum li cas ntawm cov immersion hom.
Tsis tas li ntawd, feem ntau ntawm cov khoom siv hluav taws xob no tau muab tso rau hauv qhov chaw uas cov huab cua ncig, thiab cov evaporation ntawm cov dej txias kuj tshem tawm ib feem ntawm cov cua sov, uas tuaj yeem txo qhov kub ntawm cov dej txias thiab ua kom lub zog tsav rau cov cua sov. hloov. Yog li ntawd, piv nrog rau hom immersed, lub tshav kub hloov cov nyhuv ntawm cov tshuaj tsuag kub exchanger yog zoo heev.

(1) Kev ua haujlwm siab kub hloov pauv (kev ua haujlwm zoo)
Nws yog feem ntau ntseeg hais tias lub tshav kub hloov efficiency ntawm kauv phaj kub exchanger yog 1 mus rau 3 npaug ntawm lub tubular tshav kub exchanger. Tsis muaj qhov chaw tuag nyob rau hauv ib qho kev sib tshuam ntawm ib qho channel, thiab kev cuam tshuam ntawm cov kab ke ruaj khov thiab cov kauv channel txo qhov tseem ceeb ntawm Reynolds cov kua dej. Thaum dej-dej tshav kub pauv, qhov siab tshaj plaws hloov pauv coefficient ntawm kauv phaj kub exchanger tuaj yeem ncav cuag 3000W / (㎡·K).
(2) Muaj txiaj ntsig zoo rov qab los ntawm cov cua kub tsis tshua muaj zog
Lub kauv phaj kub exchanger yog ua los ntawm ob lub yob, uas rov qab cov cua sov khib nyiab thiab ua kom tag nrho cov cua kub uas tsis muaj zog.
(3) Muaj kev ntseeg siab ua haujlwm
Qhov kawg ntawm cov kauv channel ntawm cov uas tsis yog-detachable kauv phaj kub exchanger yog welded thiab kaw, yog li nws muaj siab sealing kev ua tau zoo thiab xyuas kom meej tias ob tug ua hauj lwm xov xwm tsis sib tov.
(4) Tsawg tsis kam
Cov yeeb nkab txuas ntawm lub plhaub tau txais cov qauv tangential. Tsawg siab poob, ua cov ntim loj los yog roj; kev tu tus kheej muaj peev xwm, vim hais tias qhov nruab nrab ntws hauv cov kauv, av tsis yooj yim rau kev tso nyiaj; yooj yim los ntxuav, tuaj yeem ntxuav nrog chav lossis lye, yooj yim thiab yooj yim, haum rau kev txhim kho cov khoom siv tu; Qhov nruab nrab mus los ntawm ib qho channel, tso cai rau tus nqi ntws siab dua li lwm cov khoom siv hluav taws xob.
(5) Ntau chav nyob tuaj yeem siv ua ke
Thaum ib qho khoom siv tsis tuaj yeem ua tau raws li qhov yuav tsum tau siv, ntau yam khoom siv tuaj yeem siv ua ke. Tab sis kev sib xyaw ua ke yuav tsum ua raws li cov cai hauv qab no: kev sib xyaw ua ke, kev sib xyaw ua ke, sib nrug ntawm cov khoom siv thiab cov channel. Kev sib xyaw ua ke: Ib qho channel txuas nrog nyob rau hauv parallel thiab ib channel txuas nrog hauv series.
