Txheej txheem cej luam
Thaum tshav kub kub exchanger(heat exchanger), yog cov kua dej kub ntawm cov cua kub hloov mus rau cov khoom siv dej txias, tseem hu ua cov khoom siv hluav taws xob. Lub tshav kub exchanger yog ib qho tseem ceeb nyob rau hauv tshuaj, roj av, hwj chim, khoom noj khoom haus, thiab ntau lwm yam kev lag luam, nws cov cua kub exchanger nyob rau hauv cov tshuaj siv tau los ua ib lub rhaub, txias, condenser, evaporator reboiler, thiab lwm yam., dav siv.
Kev faib tawm
Rau cov xov xwm sib txawv, cov kev ua haujlwm sib txawv, qhov sib txawv ntawm qhov kub thiab txias, qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv, cov qauv qauv kuj txawv, qhov tshwj xeeb ntawm cov khoom siv hluav taws xob sib txawv yog raws li hauv qab no:
1, Raws li kev faib tawm ntawm cov txheej txheem hloov hluav taws xob
Inter-wall kub exchanger
Lub inter-wall heat exchanger yog qhov kub ntawm qhov sib txawv ntawm ob cov kua hauv qhov chaw sib cais los ntawm cov phab ntsa ntws, los ntawm cov phab ntsa ntawm cov cua sov thiab cov kua dej convection nyob rau hauv cov phab ntsa nto, cov cua kub hloov ntawm ob lub kua. Muaj lub plhaub thiab lub raj, lub casing, thiab lwm yam khoom siv hluav taws xob. Phab ntsa-rau-wall heat exchanger yog tam sim no siv dav tshaj plaws.
Thermal cia kub exchangers
Thaum tshav kub kub cia kub exchanger los ntawm cov khoom siv tsim los ntawm lub tshav kub cia lub cev, cua sov los ntawm high-temperature kua mus rau lub low-temperature fluid, lub kub nruab nrab ua ntej los ntawm cov cua sov ntawm cov khoom kom ncav cuag ib tug tej yam kub thiab txias, qhov nruab nrab txias thiab tom qab ntawd los ntawm cov khoom siv yog rhuab, kom nws ua tiav lub hom phiaj ntawm kev hloov hluav taws xob. Lub tshav kub accumulator heat exchanger muaj hom teb, valve hloov hom, thiab lwm yam.
Fluid-connected indirect heat exchanger
Cov kua hluav taws xob txuas ncaj qha hluav taws xob yog lub tshuab hluav taws xob hluav taws xob uas muaj ob lub tshuab hluav taws xob sib txuas sib txuas los ntawm cov khoom siv hluav taws xob uas muaj nyob hauv lawv, cov khoom siv hluav taws xob sib txuas ntawm cov hluav taws xob hluav taws xob hluav taws xob kub thiab cov kua hluav taws xob tsawg, tau txais cov cua sov hauv qhov siab- cov kua dej kub, thiab tso cua sov rau cov kua dej uas tsis muaj qhov kub thiab txias hauv cov dej kub uas tsis tshua muaj hluav taws kub exchanger.
Tiv tauj ncaj qha tshav kub exchangers
Kuj tseem hu ua hybrid heat exchanger, hom kev sib hloov hluav taws xob no yog ib qho khoom siv uas ob lub kua dej nkag mus rau hauv kev sib cuag ncaj qha thiab sib tov rau kev sib hloov cua sov, piv txwv li, cov dej txias ntauwd, roj condenser, thiab lwm yam.
Compound tshav kub exchanger
Kev sib xyaw ua ke ntawm chav dej thiab dej saum npoo hom indirect heat exchange and water and water direct mix flow heat exchange is two types of heat exchange equipment. Piv nrog rau vapor-dej nto hom indirect tshav kub hloov, nrog ntau dua tshav kub hloov efficiency; nrog rau cov vapor-dej ncaj qha sib xyaw cov cua sov hloov pauv piv rau kev ruaj ntseg siab dua thiab qis dua lub suab nrov.
2, Kev faib tawm los ntawm kev siv
Lub tshuab cua sov
Lub tshuab cua sov yog ua kom sov cov kua dej mus rau qhov tsim nyog kub, tab sis cov kua cua sov tsis tshwm sim hauv theem hloov.
Preheater
Preheaters pre-kub kua dej los muab cov txheej txheem txheej txheem rau cov txheej txheem ua haujlwm.
Superheater
Lub superheater yog siv los ua kom sov cov kua dej (cov txheej txheem roj los yog chav dej) mus rau lub xeev superheated.
Evaporator
Cov evaporators yog siv los ua kom cov kua dej kub kom kub siab tshaj qhov kub ntawm qhov kub kom cov kua evaporates thiab feem ntau muaj cov theem hloov.
3, Kev faib tawm los ntawm cov qauv
Nws tuaj yeem muab faib ua cov khoom siv hluav taws xob hauv lub taub hau, cov khoom siv hluav taws xob ruaj khov, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam.
Kev lag luam xwm txheej
Thaum tshav kub kub exchangers nyob rau hauv roj av, tshuaj, lub teeb kev lag luam, tshuaj, lub zog, thiab lwm yam industrial ntau lawm, feem ntau yog siv rau low-temperature fluid heating los yog high-temperature fluid cooling, kua vaporization rau hauv chav, los yog chav condensation rau hauv cov kua.
Thaum tshav kub kub exchangers tuaj yeem yog ib chav tsev ntawm cov khoom siv, xws li cua sov, cua txias condensers, thiab lwm yam; tab sis kuj ua cov khoom siv, xws li ammonia synthesis ntauwd heat exchangers. Lub tshav kub exchanger yog ib qho tseem ceeb ntawm cov cuab yeej siv hauv kev tsim tshuaj, raws li kev txheeb cais, lub tonnage ntawm lub tshav kub exchanger account rau txog 20% ntawm tag nrho cov txheej txheem cov cuab yeej ib co mus txog rau 30%, yog li nws tseem ceeb yuav xav txog tej yam.
