Evaporator los ua ke txoj kev xa mus rau cov organic kev koom ua ke ntawm cov tub ntxhais xws li hloov tshav kub, sib cais, ntws, thiab kev tswj raws li cov txheej txheem yuav tsum tau thiab kev khiav hauj lwm tej yam kev mob, tsim ib tug tag nrho haumxeeb thiab ruaj khov thaum tshav kub kub pauv khoom. Nws txoj kev tsim kho tsis yog tsuas yog xaiv cov qauv qauv xwb tab sis kuj tseem ceeb xws li kev sib hloov ntawm qhov chaw tshav kub, lub koom haum khiav tawm, kev sib koom ua ke, thiab cov khoom sib txuam, ncaj qha txiav txim siab cov khoom siv hluav taws xob hloov hluav taws xob, kev hloov pauv, thiab kev ntseeg tau.
Nyob rau hauv cov nqe lus ntawm cov yam ntxwv tseem ceeb, cov evaporator feem ntau muaj lub plhaub, cov khoom siv hluav taws xob sib txuas (los yog cov phaj kub sib txawv), cov khoom siv faib ua kua, vapor -kua qhov chaw sib cais, thiab cov khoom siv hluav taws xob / qhov hluav taws xob. Lub plhaub muab lub siab bearing thiab sealing ciam teb; nws cov duab thiab qhov ntev yuav tsum sib npaug ntawm qhov sib npaug ntawm qhov sib npaug thiab kev tsim khoom. Lub tshav kub exchanger raj pob yog lub hauv paus ntawm cov cua kub hloov, feem ntau yog siv puag ncig, elliptical, los yog irregularly zoo li lub raj. Nyob ntawm qhov nruab nrab viscosity thiab scaling nyiam, nws tuaj yeem tsim raws li cov raj ncaj, U- cov raj zoo li tus, los yog cov kav raj, muab tso rau hauv daim duab peb sab lossis squares kom ua kom zoo dua qhov chaw hloov hluav taws xob thiab qhov sib npaug ntawm qhov sib npaug. Phaj evaporators, nrog rau lawv cov corrugated daim hlau stacked los ua cov ntws raws, yog compact thiab muaj ib tug high heat transfer coefficient, ua rau lawv haum rau cua sov -rhiab heev los yog qhov chaw- txwv tsis pub siv.
Cov khoom faib ua kua yog tsim los ua kom tiav cov kua sib txawv ntawm cov khoom siv hluav taws xob sib txawv, tiv thaiv kev sib txawv ntawm qhov sib txawv thiab qhov chaw qhuav. Poob zaj duab xis evaporators feem ntau siv cov tshuaj tsuag los yog cov dej ntws tawm kom ntseeg tau tias cov yeeb yaj kiab ua kua ntws sib npaug ntawm lub raj phab ntsa lossis phaj nto; nce zaj duab xis evaporators cia siab rau ib tug distributor coj cov kua mus rau hauv lub cua sov cheeb tsam, qhov twg lub chav nqa nqa lub tsim ntawm ib tug nyias zaj duab xis boiling. Ib lub qhov dej zoo- tsim cov kua xa tawm tuaj yeem txo qhov kev pheej hmoo ntawm cov cua sov hauv zos thiab ntsuas qhov ntsuas, txhim kho evaporation stability.
Kev tsim cov vapor- qhov chaw sib cais kua yog ib qho tseem ceeb ntawm qhov system. Lub chamber sib cais feem ntau yog nyob rau saum toj ntawm thaj chaw cua sov, siv nws qhov loj hla -section kom txo qhov nrawm nrawm, tso cai rau cov tee dej poob rov qab rau hauv lub ntiajteb txawj nqus lossis inertia, kom ntseeg tau qhov purity ntawm qhov hluav taws xob qhov hluav taws xob. Rau cov ntaub ntawv uas ua rau foaming los yog nrog rau qhov tseem ceeb entrainment, ib tug hlau mesh demister los yog cyclone separator yuav muab ntxiv los txhim kho kev sib cais efficiency.
Lub koom haum pabcuam muaj xws li cua sov nruab nrab ntawm lub tshuab nqus tsev, lub tshuab nqus tsev, pub thiab tso cov twj tso kua mis, cov khoom siv rov ua kom rov zoo, thiab cov cuab yeej saib xyuas thiab tswj. Cov cua sov nruab nrab ntawm lub voj voog yuav tsum tau sib phim nrog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib hloov kom ruaj khov; lub tshuab nqus tsev tswj lub teeb siab kom txo qhov kub ntawm qhov kub thiab ua kom zoo dua qhov kub hloov pauv kub sib txawv; cov cuab yeej saib xyuas thiab tswj tau ua kom muaj tseeb- lub sijhawm saib xyuas thiab tawm tswv yim tswj qhov kub, siab, qib kua, thiab tus nqi ntws.
Cov khoom sib txuam yog ib qho tseem ceeb ntawm txoj kev sib dhos no. Lub plhaub tsim nyog thiab cov khoom siv hluav taws xob hloov hluav taws xob yuav tsum raug xaiv raws li qhov corrosiveness ntawm qhov nruab nrab, qhov kub thiab txias kom ntseeg tau tias muaj kev ruaj ntseg thiab ruaj khov.
Hauv cov ntsiab lus, cov txheej txheem evaporator sib dhos, nrog rau kev faib tawm thiab kev sib koom ua ke ntawm cov haujlwm ua haujlwm raws li nws cov tub ntxhais kawm, ua tiav cov txheej txheem evaporation zoo thiab txhim khu kev qha los ntawm kev ua kom zoo dua ntawm cov qauv, ntws, thiab tswj, muab lub platform muaj zog rau ntau yam kev siv.
