Hauv kev lag luam kua txiv hmab txiv ntoo, phaj evaporator muaj qhov zoo hauv qab no thiab siv dav:
1. Kev nkag tau zoo: Phaj cua sov exchanger muaj ib txheej ntawm cov phaj kub exchanger tsau rau ntawm ib lub thav duab, nrog cov phaj sib cais los ntawm ib tug gasket, los yog ob daim hlau brazed los ua ib hom ntawm lub thawv-hom tivthaiv, nrog ib tug vapor channel nyob rau hauv nruab nrab. Cov phaj tau yooj yim tshem tawm thiab tag nrho cov tshav kub hloov chaw tuaj yeem tshawb xyuas pom tau yooj yim. Yog tias muaj teeb meem xws li kev sib tw khiav thiab kev ntsuas, cov phiaj tuaj yeem raug tshem tawm thiab cov khoom siv hluav taws xob tuaj yeem raug ntxuav los ntawm tes. Daim phiaj tus kheej tuaj yeem hloov tau yog tias lawv puas lawm. Tus naj npawb ntawm daim hlau tuaj yeem yooj yim nce lossis txo.
2. Thaum cov khoom hloov pauv lossis hloov cov txheej txheem, yog tias tsim nyog, tus lej ntawm daim hlau tuaj yeem nce lossis txo qis los kho cov txheej txheem ua haujlwm ntawm cov khoom siv, kom tau txais txiaj ntsig zoo tshaj plaws. Nws tuaj yeem raug txo mus rau 40 feem pua ntawm cov peev txheej qub.
3. Nyob rau hauv tib lub tshav kub exchanger, qhov siab ntawm phaj kub exchanger yog npaum li cas me dua lub raj kub exchanger, phaj kub exchanger rau qhov siab ntawm chav tsev yog heev tsawg, txawm rau lub loj-scale evaporator, yuav ua tau rau tag nrho. qhov siab ntawm cov cuab yeej hauv 5 meters lossis tsawg dua, uas txhais tau hais tias cov qauv ntawm cov nroj tsuag yog yooj yim dua, tus nqi kuj tseem qis dua. Vim qhov txo qhov ntim, tag nrho cov txheej txheem ntawm cov cuab yeej siv tau yooj yim dua, tsis tas yuav siv lub tshuab hnyav lossis lwm yam khoom siv tshwj xeeb, cov khoom siv kev teeb tsa raug txo raws li.
4. Cov khoom nyob rau hauv lub evaporator rau ib lub sij hawm luv luv, ntau yam khoom yuav tsum tau evaporated yog kub-rhiab, thiab nyob twj ywm rau ib lub sij hawm ntawm qhov kub thiab txias yuav ua rau ib feem ntawm cov khoom xyaw puas, thiab cov khoom qab zib yuav txo tau thiab nws cov xim yuav tsaus. Phaj heat exchanger heat transfer coefficient yog tube heat exchanger 2-4 zaug, tib lub sij hawm, vim qhov chaw ntawm qhov chaw ntim me me, koj tuaj yeem tsim ib cheeb tsam loj ntawm cov cua sov hloov, kom cov kua yuav tsum tau evaporated hauv. lub sij hawm nyob rau hauv tshav kub exchanger yuav luv luv rau 1/3 ~ 1/4, zoo heev txhim kho cov khoom zoo.
5. Vim yog lub siab hloov pauv coefficient, cov kua tuaj yeem dhau los ntawm cov khoom siv hluav taws xob sai dua, thiab qhov ntim ntawm cov kua khaws cia hauv cov khoom siv hluav taws xob txo qis rau 1/2 ~ 1/4, kom tag nrho cov evaporator tuaj yeem ncav cuag. equilibrium xeev nyob rau hauv ib lub sij hawm luv luv thaum pib ntawm cov txheej txheem evaporation.
6. Rau siab viscosity kua, phaj kub exchanger yog tsim nyog, vim hais tias ntawm high heat transfer coefficient, cov kua yuav kis tau los ntawm lub phaj kub exchanger nrog ib tug ceev ceev, thiab nyob rau hauv qhov kev txiav txim ntawm tus qauv ntawm lub phaj. , muaj zog turbulence yuav tsim, kom nws tsis yooj yim rau adhered rau ntawm qhov chaw ntawm lub tshav kub exchanger, ntawm qhov tod tes, txawm rau lub siab viscosity kua, nws tseem muaj peev xwm mus cuag ib tug high tshav kub hloov coefficient. Lub phaj kub exchanger hom evaporator muaj qee qhov zoo hauv kev soj ntsuam nrog cov kua dej ntau dua viscosity.
7. Qhov siab ntawm kev kub ntxhov tshwm sim los ntawm cov qauv ntawm cov phaj tsis tsuas yog nyiam cov cua sov hloov mus, tab sis kuj ua rau hauv-situ tu sai thiab zoo dua. Cov phaj tseem tuaj yeem hloov tau thaum muaj qhov loj me uas tsis tuaj yeem ntxuav.
8. Qhov kub ntawm qhov sib txawv ntawm txhua qhov cuam tshuam yog me dua li ntawm lub plhaub thiab lub raj hom. Thaum ua ntau yam cuam tshuam evaporator, qhov kub ntawm thawj cov nyhuv tuaj yeem qis dua, thiab cov nyhuv tuaj yeem nce ntxiv lossis cov khoom tuaj yeem kho tau maj mam.
Hauv cov xwm txheej hauv qab no, lub phaj kub hloov pauv tsis siv tau, tab sis yuav tsum siv lub raj cua kub exchanger.
1. thaum lub siab ua hauj lwm siab tshaj 2 bar.
2. sealing rings yuav tsum tau nruab nrab ntawm cov phaj ntawm lub phaj kub exchanger, thaum lub nruab nrab ua hauj lwm yog li txwv.
3. rau cov kua yuav tsum tau concentrated nyob rau hauv cov ntaub ntawv ntawm cov khoom loj tshem tawm hais tias (particle loj ntawm 2mm thiab saum toj no), yuav tsum tau siv lub raj kub exchanger.
4. rau cov evaporator loj ntxiv, cov phaj loj ua haujlwm yog qhov nyuaj dua, feem ntau siv lub raj cua kub exchanger, tab sis nrog kev txhim kho ntawm cov phaj txheej txheem, tam sim no muaj 100 tonnes / teev evaporation muaj peev xwm ntawm phaj evaporation chav ua kom tiav.
