I: Kub exchanger classification
1, cais raws li kev siv cov khoom siv hluav taws xob
(1) Lub rhaub dej kub: Lub rhaub dej kub yog siv los ua kom sov cov kua dej mus rau qhov xav tau qhov kub thiab txias ntawm cov kua dej tsis hloov pauv thaum lub sijhawm cua sov.
(2) Preheater: Preheater yog siv los preheat cov kua los txhim kho kev ua haujlwm ntawm tag nrho cov txheej txheem.
(3) Superheater: Lub superheater yog siv los ua kom sov lub vapor saturated mus rau lub xeev superheated.
(4) Evaporator: Cov evaporator yog siv los ua kom sov cov kua kom evaporate thiab vaporise nws.
(5) reboiler: reboiler yog cov txheej txheem distillation ntawm cov cuab yeej tshwj xeeb, siv los ua kom sov cov kua uas tau condensed kom nws rov ua kom sov thiab vaporised.
(6) Cooler: lub cooler yog siv los ua kom cov dej txias kom nws ncav cuag qhov kub thiab txias.
(7) condenser: condenser siv rau condense saturated vapor thiaj li tso tawm ntawm latent cua sov thiab condensation liquefaction.
2, raws li lub tshav kub exchanger tshav kub hloov qhov chaw zoo thiab cov qauv kev faib tawm
(1) Tubular tshav kub exchanger: Tubular tshav kub exchanger tshav kub hloov mus los ntawm lub phab ntsa ntawm lub raj, raws li cov qauv ntawm lub tshav kub hloov tube yog txawv, yuav muab faib ua kem tube tshav kub exchanger, casing hom kub exchanger, nab raj kub exchanger thiab finned tube cua sov exchanger thiab thiaj li nyob rau ntau yam ntawm tshav kub exchanger. Lub raj kub exchanger yog siv dav tshaj plaws.
(2) phaj kub exchanger: phaj kub exchanger tshav kub hloov los ntawm lub phaj, raws li cov qauv qauv ntawm lub tshav kub hloov phaj, yuav muab faib ua pav ca phaj kub exchanger, kauv phaj kub exchanger, phaj-fin hom kub exchanger thiab kub phaj kub exchanger.
(3) Daim ntawv tshwj xeeb ntawm cov khoom siv hluav taws xob: cov khoom siv hluav taws xob no yog tsim los ntawm cov txheej txheem tshwj xeeb ntawm cov txheej txheem nrog cov qauv tshwj xeeb ntawm cov khoom siv hluav taws xob. Xws li cov khoom siv hluav taws xob hloov hluav taws xob, thiab cov khoom siv hluav taws xob cua sov.
3, cais raws li cov khoom siv hauv cov khoom siv hluav taws xob
(1) Hlau cov ntaub ntawv kub exchanger: Cov ntaub ntawv hlau kub exchanger yog ua los ntawm cov ntaub ntawv hlau, feem ntau siv cov ntaub ntawv hlau yog carbon steel, alloy steel, tooj liab thiab tooj liab alloy, txhuas thiab txhuas alloy, thiab titanium thiab titanium alloy. Vim tias cov thermal conductivity ntawm cov ntaub ntawv hlau, cov khoom siv hluav taws xob hloov hluav taws xob ntawm cov khoom siv hluav taws xob no siab dua, cov khoom siv feem ntau yog siv rau hauv cov khoom siv hlau kub exchangers.
(2) Cov ntaub ntawv tsis yog xim hlau kub exchanger: cov ntaub ntawv uas tsis yog xim hlau kub exchanger ua los ntawm cov ntaub ntawv uas tsis yog xim hlau, feem ntau siv cov ntaub ntawv uas tsis yog kub xws li graphite, iav, yas thiab ceramics. Hom kev sib hloov cua sov no feem ntau yog siv rau cov ntaub ntawv corrosive vim thermal conductivity ntawm cov ntaub ntawv tsis yog xim hlau yog me me, yog li nws cov kev hloov pauv hluav taws xob tsawg.
Phaj kub exchangerqauv thiab cov yam ntxwv ua haujlwm
1. Phaj kub exchanger
Pav ca phaj kub exchanger hu ua phaj kub exchanger, nws cov qauv yog qhia nyob rau hauv daim duab 4-46. Nws yog ib txheej ntawm cov duab plaub nyias hlau daim hlau teem nyob rau hauv parallel, clamped los ua ke nyob rau hauv lub bracket saum toj no muaj pes tsawg leeg. Lub ntug ntawm ob daim hlau nyob sib ze yog hlua nrog gaskets thiab nias ntawm daim hlau los tsim cov kua dej sib txuas, thiab lub thickness ntawm lub gasket tuaj yeem siv los kho qhov loj ntawm cov channel. Plaub lub kaum sab xis ntawm txhua lub phaj, txhua qhov qhib ib puag ncig lub qhov, ntawm ob lub qhov puag ncig thiab cov dej ntws ntws ntawm lub phaj, lwm qhov ob qhov sib txuas tsis txuas nrog. Lawv txoj haujlwm yog staggered ntawm cov phiaj nyob sib ze los tsim cov kev sib cais rau ob lub kua dej. Cov kua dej txias thiab kub ntws sib hloov ntawm ob sab ntawm daim hlau, thiab cov cua sov yog pauv los ntawm cov hlau phaj.
Lub phaj yog cov tseem ceeb ntawm cov phaj kub exchanger. Txhawm rau ua kom cov kua dej ntws tsis sib xws los ntawm cov phaj saum npoo, ua kom cov cua sov hloov chaw, thiab txhawb cov dej turbulence, feem ntau cov phaj saum npoo yog stamped rau hauv concave-convex corrugated, corrugated duab muaj ntau ntau hom kev siv corrugated duab yog kab rov tav corrugated, herringbone corrugated thiab arched corrugated thiab lwm yam.
Phaj tshav kub exchanger muaj qhov zoo ntawm cov qauv compact, chav tsev ntim ntawm cov khoom siv los muab thaj tsam loj ntawm cov cua sov hloov; kev sib dhos yooj yim, raws li qhov yuav tsum tau ua kom nce lossis txo tus naj npawb ntawm daim hlau los tswj qhov kub hloov chaw; phaj ripples ua rau kev hloov pauv ntawm ntu ntu hauv qhov nyuaj ntawm cov kua dej los txhim kho cov nyhuv perturbation, nrog rau kev ua kom sov siab; yooj yim rau disassemble, conducive rau tu thiab tu. Qhov tsis zoo yog tias lub peev xwm ua tau me me; kev khiav hauj lwm siab thiab kub los ntawm cov sealing gasket cov ntaub ntawv kev ua tau zoo txwv thiab yuav tsum tsis txhob siab dhau. Lub phaj kub exchanger yog haum rau kev tu ntau zaus, qhov chaw ua hauj lwm yog compact heev, kev ua hauj lwm siab yog qis dua 2.5 MPa, thiab qhov kub yog -35 degree ~ 200 degree zaus.
